Claim Rejections - 35 USC § 103
The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action:
A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made.
Claim(s) 4 and 14 are rejected under 35 U.S.C. 103 as being unpatentable over Krueger et al. (U.S. 2018/0056960A1) in view of Strengert et al. (U.S. 2010/0198473A1). Strengert discloses “If a wheel actuator device 30a or 30b detects that its associated brake control device 28a or 28b has failed, it no longer performs the braking operation on its wheel as a function of the control signal of its own brake control device 28a or 28b. Instead, wheel actuator device 30a or 30b begins with the evaluation of the sensor signals 18a, 18b, 24a, 24b, 26a and 26b transmitted directly to it. On the basis of these sensor signals 18a, 18b, 24a, 24b, 26a and 26b, wheel actuator device 30a or 30b ascertains what braking torque it should exert on its associated wheel” (¶0052; Fig. 3) and “If a situation occurs in brake system 80 such that both brake control devices 28a and 28b fail, then in this case it is also still possible to perform a braking operation controlled by sensor signals 18a, 18b, 24a, 24b, 26a and 26b. This may be ensured because, after a failure of the two brake control devices 28a and 28b, the respective sensor signals 18a, 18b, 24a, 24b, 26a and 26b are transmitted to wheel actuator devices 30a and 30b. “ (¶0062).
Regarding Claims 4 and 14, Krueger teaches all the elements of Claims 1 and 11 as indicated above. Krueger does not explicitly teach: wherein: the first drive is configured to receive the output of the first pedal sensor and control the current driving the first motor to brake the first wheel based on the output of the first pedal sensor in response to a state that the first and second processors are in a failure state; and the second drive is configured to receive the output of the second pedal sensor and control the current driving the second motor to brake the second wheel based on the output of the second pedal sensor in response to the state that the first and second processors are in the failure state or receiving, by the first drive integrated with the first processor, the output of the first pedal sensor; controlling, by the first drive, the current driving the first motor to brake the first wheel based on the output of the first pedal sensor in response to a state that the first and second processors are in a failure state; receiving, by the second drive integrated with the second processor, the output of the second pedal sensor; controlling, by the second drive, the current driving the second motor to brake the second wheel based on the output of the second pedal sensor in response to the state that the first and second processors are in the failure state
Strengert teaches: wherein: the first drive is configured to receive the output of the first pedal sensor (“wheel actuator device 30a or 30b begins with the evaluation of the sensor signals 18a, 18b, 24a, 24b, 26a and 26b transmitted directly to it”) and control the current driving the first motor to brake the first wheel based on the output of the first pedal sensor in response to a state that the first and second processors are in a failure state (¶0052; Fig. 3; ¶0062; “If a situation occurs in brake system 80 such that both brake control devices 28a and 28b fail”); and the second drive is configured to receive the output of the second pedal sensor (“wheel actuator device 30a or 30b begins with the evaluation of the sensor signals 18a, 18b, 24a, 24b, 26a and 26b transmitted directly to it”) and control the current driving the second motor to brake the second wheel based on the output of the second pedal sensor in response to the state that the first and second processors are in the failure state (¶0052; Fig. 3; ¶0062) in order to “ensure that, following a failure of several components of its brake system, a vehicle is braked either automatically or a braking operation of the vehicle initiated by the driver is performed.” (¶0020) and receiving, by the first drive integrated with the first processor, the output of the first pedal sensor (“wheel actuator device 30a or 30b begins with the evaluation of the sensor signals 18a, 18b, 24a, 24b, 26a and 26b transmitted directly to it”); controlling, by the first drive, the current driving the first motor to brake the first wheel based on the output of the first pedal sensor in response to a state that the first and second processors are in a failure state (¶0052; Fig. 3; ¶0062); receiving, by the second drive integrated with the second processor, the output of the second pedal sensor (“wheel actuator device 30a or 30b begins with the evaluation of the sensor signals 18a, 18b, 24a, 24b, 26a and 26b transmitted directly to it”); controlling, by the second drive, the current driving the second motor to brake the second wheel based on the output of the second pedal sensor in response to the state that the first and second processors are in the failure state (¶0052; Fig. 3; ¶0062) in order to “ensure that, following a failure of several components of its brake system, a vehicle is braked either automatically or a braking operation of the vehicle initiated by the driver is performed.” (¶0020)
It would have been obvious to one with ordinary skill in the art at the time of filing of the invention to have modified the braking control system of Krueger to incorporate the teachings of Strengert to include wherein: the first drive is configured to receive the output of the first pedal sensor and control the current driving the first motor to brake the first wheel based on the output of the first pedal sensor in response to a state that the first and second processors are in a failure state; and the second drive is configured to receive the output of the second pedal sensor and control the current driving the second motor to brake the second wheel based on the output of the second pedal sensor in response to the state that the first and second processors are in the failure state and receiving, by the first drive integrated with the first processor, the output of the first pedal sensor; controlling, by the first drive, the current driving the first motor to brake the first wheel based on the output of the first pedal sensor in response to a state that the first and second processors are in a failure state; receiving, by the second drive integrated with the second processor, the output of the second pedal sensor; controlling, by the second drive, the current driving the second motor to brake the second wheel based on the output of the second pedal sensor in response to the state that the first and second processors are in the failure state in order to “ensure that, following a failure of several components of its brake system, a vehicle is braked either automatically or a braking operation of the vehicle initiated by the driver is performed.” (¶0020)
Claim(s) 5-7 and 15-17 are rejected under 35 U.S.C. 103 as being unpatentable over Krueger et al. (U.S. 2018/0056960A1) in view of Hwang (U.S. 2021/0370895A1). Hwang discloses “The first wheel speed sensor 10 and the second wheel speed sensor 20 are disposed on each of the vehicle wheels and used to calculate the wheel speed of each wheel. The first wheel speed sensor 10 transmits a wheel speed-related signal to the main controller 50. The second wheel speed sensor transmits a wheel speed detection signal to the auxiliary controller 60.” (Fig. 1-2; ¶0017) and “When the main controller 50 loses the driving function or the braking function of the vehicle, the auxiliary controller 60 may take the place of those functions. The main controller 50 and the auxiliary controller 60 may be physically disposed adjacent to each other or may be separated and disposed at separate locations inside the vehicle. The braking unit 70 is arranged to receive a braking signal from the main controller 50 or the auxiliary controller 60 and distribute the braking force to the respective vehicle wheels.” (¶0030-0031)
Regarding Claims 5 and 15, Krueger further discloses the first processor (Fig. 2c, 200a) is communicationally connected with a first wheel speed sensor (¶0022, 122a) configured to measure a rotational speed of the first wheel; and the second processor (Fig. 2c, 200b) is communicationally connected with a fourth wheel speed sensor(Fig. 2c, 122b, ¶0022) configured to measure the rotational speed of the second wheel
And
receiving, by the first processor (Fig. 2c, 200a), an output of the first wheel speed sensor (¶0022, 122a) configured to measure a rotational speed of the first wheel and an output of the second wheel speed sensor (Fig. 2c, 122b, ¶0022) configured to measure a rotational speed of the second wheel; and receiving, by the second processor (Fig. 2c, 200b), an output of the third wheel speed sensor configured to measure the rotational speed of the first wheel and an output of the fourth wheel speed sensor (Fig. 2c, 122b, ¶0022) configured to measure the rotational speed of the second wheel
Krueger does not explicitly teach the first processor is communicationally connected with a first wheel speed sensor configured to measure a rotational speed of the first wheel and a second wheel speed sensor configured to measure a rotational speed of the second wheel; and the second processor is communicationally connected with a third wheel speed sensor configured to measure the rotational speed of the first wheel and a fourth wheel speed sensor configured to measure the rotational speed of the second wheel or receiving, by the first processor, an output of the first wheel speed sensor configured to measure a rotational speed of the first wheel and an output of the second wheel speed sensor configured to measure a rotational speed of the second wheel; and receiving, by the second processor, an output of the third wheel speed sensor configured to measure the rotational speed of the first wheel and an output of the fourth wheel speed sensor configured to measure the rotational speed of the second wheel.
Hwang teaches: the first processor (Fig. 2, 50) is communicationally connected with a first wheel speed sensor (10a) configured to measure a rotational speed of the first wheel and a second wheel speed sensor(10b) configured to measure a rotational speed of the second wheel; and the second processor (60) is communicationally connected with a third wheel speed sensor(20a) configured to measure the rotational speed of the first wheel and a fourth wheel speed sensor (20b) configured to measure the rotational speed of the second wheel in order to ensure stability of the vehicle based on ability to calculate wheel speed from a secondary wheel speed sensor in response to determining presence or abnormality of a primary wheel speed sensor on each wheel. (¶0038)
And
receiving, by the first processor(Fig. 2, 50), an output of the first wheel speed sensor (10a) configured to measure a rotational speed of the first wheel and an output of the second wheel speed sensor(10b) configured to measure a rotational speed of the second wheel; and receiving, by the second processor(60), an output of the third wheel speed sensor (20a) configured to measure the rotational speed of the first wheel and an output of the fourth wheel speed sensor (20b) configured to measure the rotational speed of the second wheel in order to ensure stability of the vehicle based on ability to calculate wheel speed from a secondary wheel speed sensor in response to determining presence or abnormality of a primary wheel speed sensor on each wheel. (¶0038)
It would have been obvious to one with ordinary skill in the art at the time of filing of the invention to have modified the brake control system of Krueger to incorporate the teachings of Hwang to include the first processor is communicationally connected with a first wheel speed sensor configured to measure a rotational speed of the first wheel and a second wheel speed sensor configured to measure a rotational speed of the second wheel; and the second processor is communicationally connected with a third wheel speed sensor configured to measure the rotational speed of the first wheel and a fourth wheel speed sensor configured to measure the rotational speed of the second wheel and receiving, by the first processor, an output of the first wheel speed sensor configured to measure a rotational speed of the first wheel and an output of the second wheel speed sensor configured to measure a rotational speed of the second wheel; and receiving, by the second processor, an output of the third wheel speed sensor configured to measure the rotational speed of the first wheel and an output of the fourth wheel speed sensor configured to measure the rotational speed of the second wheel in order to ensure stability of the vehicle based on ability to calculate wheel speed from a secondary wheel speed sensor in response to determining presence or abnormality of a primary wheel speed sensor on each wheel. (¶0038).
Regarding Claims 6 and 16, the combination of Krueger and Hwang teaches all the elements of Claims 5 and 15 as indicated above. Krueger further discloses “The EBS controller 200 is also configured to calculate, select, and/or otherwise determine a corresponding braking request or braking event in response to the detected and recorded measurements or readings output from the wheel sensors 122a and 122b. Based on the determined braking request or braking event, the EBS controller 200 outputs a low voltage data command signal that invokes a braking action to slow down the vehicle 100 as discussed in greater detail herein.” (¶0021; in other words, the controllers are configured to selectively (i.e. intermittently) apply a braking action to respective wheels based on the readings or outputs from the respective wheel speed sensors.)
Therefore Krueger further discloses:
wherein: the first processor (Fig. 2c, 200a) is configured to transmit a fifth control signal (Fig. 2c, ‘low voltage data command signal that invokes braking action; ¶0021-0022)to the first drive(202a), configured to control the current driving the first motor, to intermittently brake the first wheel based on an output of the first wheel speed sensor configured to measure the rotational speed of the first wheel (¶0021-0022); and the second processor (200b)is configured to transmit a sixth control signal(Fig. 2c, ‘low voltage data command signal that invokes braking action; ¶0021-0022) to the second drive (202b), configured to control the current driving the second motor, to intermittently brake the second wheel based on an output of the second wheel speed sensor (Fig. 2c, 122b; ¶0021-0022) configured to measure the rotational speed of the second wheel

Regarding Claims 7 and 17, the combination of Krueger and Hwang teaches all the elements of Claims 6 and 16 as indicated above. Krueger further discloses wherein: the first processor is configured to transmit a seventh control signal to the first and second drives, configured to control the currents driving the first and second motors respectively, to intermittently brake the first and second wheels based on the output of the first wheel speed sensor configured to measure the rotational speed of the first wheel and an output of the second wheel speed sensor configured to measure the rotational speed of the second wheel when the second processor is in a failure state, the second processor is configured to transmit an eighth control signal to the first and second drives, configured to control the currents driving the first and second motors respectively, to intermittently brake the first and second wheels based on the output of the third wheel speed sensor configured to measure the rotational speed of the first wheel and an output of the fourth wheel speed sensor configured to measure the rotational speed of the second wheel when the first processor is in the failure state (¶0047; Fig. 4; “Referring back to operation 406, a scenario may occur where the braking event data monitored and generated by the first EBS controller does not match or substantially match the braking event data monitored and generated by the second EBS controller.

And
transmitting, by the first processor, a seventh control signal to the first and second drives, configured to control the current driving the first and second motors respectively, to intermittently brake the first and second wheels based on the outputs of the first and second wheel speed sensors, configured to measure the rotational speeds of the first and second wheels respectively, in response to a state that the second processor is in a failure state; and transmitting, by the second processor, an eighth control signal to the first and second drives, configured to control the current driving the first and second motors respectively, to intermittently brake the first and second wheels based on the outputs of the third and fourth wheel speed sensors, configured to measure the rotational speeds of the first and second wheels respectively, in response to a state that the first processor is in the failure state (¶0047; Fig. 4; “Referring back to operation 406, a scenario may occur where the braking event data monitored and generated by the first EBS controller does not match or substantially match the braking event data monitored and generated by the second EBS controller. In this case, the method proceeds to operation 416 where one of the first EBS controller and the second EBS controller outputs a data command signal to both the first power circuit and the second power circuit. “; also ¶0041 “in this manner, if the first EBS controller 200a is unable to properly control the first power circuit 202a, the second EBS controller 200b may provide the braking event data signal necessary to command the first power circuit 202a to output the high-frequency switched high-current signal for driving the first actuator 118a in addition to continuing to provide braking event data singal to command the second power circuit 202b to output the high-frequency switched high-current signal for driving the first actuator 118b.

Claim(s) 8-9 and 18-19 are rejected under 35 U.S.C. 103 as being unpatentable over Krueger et al. (U.S. 2018/0056960A1) in view of Hwang (U.S. 2021/0370895A1) in view of Strengert et al. (U.S. 2010/0198473A1). Strengert discloses “If a wheel actuator device 30a or 30b detects that its associated brake control device 28a or 28b has failed, it no longer performs the braking operation on its wheel as a function of the control signal of its own brake control device 28a or 28b. Instead, wheel actuator device 30a or 30b begins with the evaluation of the sensor signals 18a, 18b, 24a, 24b, 26a and 26b transmitted directly to it. On the basis of these sensor signals 18a, 18b, 24a, 24b, 26a and 26b, wheel actuator device 30a or 30b ascertains what braking torque it should exert on its associated wheel” (¶0052; Fig. 3) and “If a situation occurs in brake system 80 such that both brake control devices 28a and 28b fail, then in this case it is also still possible to perform a braking operation controlled by sensor signals 18a, 18b, 24a, 24b, 26a and 26b. This may be ensured because, after a failure of the two brake control devices 28a and 28b, the respective sensor signals 18a, 18b, 24a, 24b, 26a and 26b are transmitted to wheel actuator devices 30a and 30b. “ (¶0062).
