DETAILED ACTION
Notice of Pre-AIA or AIA Status
The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA .
Claim Rejections - 35 USC § 103
In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status.
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.
The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows:
1. Determining the scope and contents of the prior art.
2. Ascertaining the differences between the prior art and the claims at issue.
3. Resolving the level of ordinary skill in the pertinent art.
4. Considering objective evidence present in the application indicating obviousness or nonobviousness.
Claim(s) 1-4,6-10 is/are rejected under 35 U.S.C. 103 as being unpatentable over Yamashita et al US 20200047764 in view of Meyer et al US 2022/0340118.
In Re 1, Yamashita teaches
1. A steering system (title) comprising:
a control unit (ECU_C/A,C/B) including at least one feedback actuator (102 fig 1) configured to generate a steering resistance (“reaction force applying device” abstract) and/or a restoring torque (optional) to a steering handle (60 fig 1) and at least one feedback control unit (110A/B) configured to control operation of the at least one feedback actuator (abstract);
at least one wheel steering angle adjuster (64 steering device para 98 and items 96ab,68b108ab) mechanically separated (fig 1 steer by wire abstract) from an operating unit (steering wheel) the at least one wheel steering angle adjuster including at least one steering actuator (68) configured to change a wheel steering angle of at least one vehicle wheel (12)and at least one steering control unit (108A, 108B) configured to control operation of the at least one steering actuator; and
a transfer unit (bus abstract, fig 3 the connecting wires/buses, e.g. 120a) configured to at least communicatively connect the operating unit and the at least one wheel steering angle adjuster to each other (figs 3,4e,5f),
wherein the at least one feedback control unit is configured, in at least one fault operating state (figs 4e,5f, abstract) in which a fault (optional) and/or failure (“failure” paras 3-4) of the at least one steering control unit occurs, the at least one steering actuator.
Yamashita does not teach however Meyer teaches a control unit (24) is configured to control another control unit (26), when one of the two control units fail (not explicitly claimed but presented for clarity of rejection)(see Meyer paras 47-58,101,102, abstract, especially para 52). Meyer further teaches redundancy of control units for reliability during failure, paras 7-8. It would have been obvious to a person having ordinary skill in the art at the time of the invention (pre-AIA ) or before the effective filing date of the invention (AIA ) to modify Yamashita’s system with Meyer’s redundant electronic control unit operation embodied that Yamashita’s feedback control unit can control the steering actuator in case of failure of steering control unit, in order to make a desirably reliable system.
In Re 2-4,6-7, Yamashita further teaches:
2. The steering system according to claim 1, wherein the at least one feedback control unit is configured to control (Markush/one of two alternatives) the at least one feedback actuator in a reduced power fault operating state (taken as optional) or to adjust a control of the at least one feedback actuator (controlling the actuator is adjusting it).
3. The steering system according to claim 1 further comprising: at least one switching unit (para 15 switches) configured to electrically connect the at least one feedback control unit to the at least one steering actuator, wherein the switching unit is integrated ( Yamashita para 15) into the operating unit and is arranged in terms of circuitry (control units are circuitry) between a power electronic system (power supply unit para 15) of the at least one feedback control unit and a transmission unit (wires/bus/wires connected to bus/electrical connections).
4. The steering system according to claim 1, wherein: the at least one wheel steering angle adjuster includes at least one detection sensor system (R_SA, R_SB) configured to detect at least one operating variable (theta 98) of the at least one steering actuator; the at least one detection sensor system is configured to transmit the at least one operating variable at least in the fault operating state to the at least one feedback control unit (110A,B); and the at least one feedback control unit is configured to control the at least one steering actuator (see in re 1 Yamashita as modified by Meyer) in the fault operating state as a function of the at least one operating variable.
6. The steering system according to claim 1, wherein: the at least one steering actuator includes at least two independent steering sub-machines (68A and 68B) and the at least one steering control unit includes at least two independent steering control electronic systems (108A and 108B), one of the at least two independent steering control electronic systems being associated with each of the at least two independent steering sub-machines; and
the at least one feedback control unit is configured, in the fault operating state, to replace at least one of the at least two independent steering control electronic systems or both of the at least two independent steering control electronic systems (see in re 1 Yamashita in view of Meyer).
7. The steering system according to claim 1, wherein: the at least one feedback actuator includes at least two independent feedback sub-machines (102A and 102B) and the at least one feedback control unit includes at least two independent feedback control electronic systems (110A and 110B), one of the at least two independent feedback control electronic systems being assigned to each of the at least two independent feedback sub-machines; and at least one of the at least two independent feedback control electronic systems is configured, in the fault operating state, to replace at least one portion of the at least one steering control unit or an entirety of the at least one steering control unit (see in re 1 Yamashita in view of Meyer).
In Re 8, the motor vehicle of claim 8 rejected over in re 1 as taught by Yamashita in view of Meyer as described above, note both prior art inventions are motor vehicles.
In Re 9,10 the method of claims 9,10 rejected over in re 1 as taught by Yamashita in view of Meyer as described above, Yamashita fig 1 abstract “steer by wire”.
Claim(s) 5 is/are rejected under 35 U.S.C. 103 as being unpatentable over Yamashita et al US 20200047764 in view of Meyer et al US 2022/0340118 and Zhao et al US 2021/0269087.
In Re 5, Yamashita in view of Meyer teaches wherein the at least one feedback control unit is configured to take control of the at least one steering actuator in the fault operating state (in re 1).
Yamashita does not teach although Zhao teaches within a predefined fault tolerance time (fault diagnosis unit in real time, paras 1,7,9,35-37,62,70-72,93).
