Office Action

§102
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 . 1. This action is responsive to application filed Oct. 3, 2024. Claim Rejections - 35 USC § 102 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 the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action: A person shall be entitled to a patent unless – (a)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention. 2. Claims 1-19 are rejected under 35 U.S.C. 102(a)(2) as being anticipated by Naserian et al., U.S. Patent Application Publication No. 2022/0105925 (referred to hereafter as Naserian). As to claims 1, 11-12, and 14, Naserian teaches a method, system and vehicle for dynamic regenerating braking of a vehicle, comprising: sensing one or more parameters associated with a driving environment of the vehicle (see para. 15 and 29, upcoming deceleration event is detected); adjusting by an electronic device a dynamic regenerative braking level prior to initiation of braking in response to the one or more parameters (see para. 29, amount of braking is determined prior to applying the brakes); and resetting the dynamic regenerative braking level by the electronic device (see para. 60). As to claim 2, Naserian teaches the method of claim 1 wherein the resetting the dynamic regenerative braking level by the electronic device occurs when an accelerator interface is re-engaged (see para. 60). As to claim 3, Naserian teaches the method of claim 2 wherein the accelerator interface comprises at least one of an accelerator pedal, a throttle grip, and a machine interface (see para. 60). As to claim 4, Naserian teaches the method of claim 2 wherein the accelerator interface comprises an accelerator pedal and wherein the accelerator pedal is re-engaged when a vehicle operator applies pressure to the accelerator pedal (see para. 60). As to claim 5, Naserian teaches the method of claim 1 further comprising applying regenerative braking at the dynamic regenerative braking level and prior to resetting the dynamic regenerative braking level by the electronic device (see para. 59-60). As to claim 6, Naserian teaches the method of claim 1 wherein the one or more parameters associated with a driving environment are indicative of a potential collision (see para. 17 and 54). As to claim 7, Naserian teaches the method of claim 1 wherein the sensing the one or more parameters associated with the driving environment is performed using a vision system (see para. 17 and 54). As to claim 8, Naserian teaches the method of claim 1 wherein the one or more parameters associated with the driving environment of the vehicle are associated with the driving environment in a forward direction of the vehicle, the vehicle traveling in the forward direction (see para. 17 and 54). As to claim 9, Naserian teaches the method of claim 1 wherein the adjusting the dynamic regenerative braking level comprises adjusting the dynamic regenerative braking level a plurality of times prior to initiation of the braking (see para. 29 and 55). As to claim 10, Naserian teaches the method of claim 1 wherein the electronic device is associated with a crash avoidance system of the vehicle (see para. 17 and 54). As to claim 13. The vehicle of claim 12 wherein the vehicle is an autonomous vehicle (see para. 35). As to claim 15. The system of claim 14 wherein the electronic device is further configured for controlling applying of regenerative braking at the dynamic regenerative braking level prior to resetting the dynamic regenerative braking level. As to claim 16. The system of claim 14 wherein the plurality of sensors include sensors associated with a vision system (see para. 17 and 54). As to claim 17. A method for dynamic regenerative braking of a vehicle operated by a vehicle operator, the method comprising steps of: sensing one or more parameters associated with a driving environment of the vehicle, the one or more parameters including parameters determined using a vision system of a vehicle position to capture the driving environment in a forward direction(see para. 15 and 29, upcoming deceleration event is detected); adjusting by an electronic device a dynamic regenerative braking level prior to initiation of braking in response to the one or more parameters (see para. 29, amount of braking is determined prior to applying the brakes); and resetting the dynamic regenerative braking level by the electronic device when the vehicle operator applies pressure to an accelerator interface (see para. 60). As to claim 18, Naserian teaches the method of claim 17 wherein the accelerator interface comprises an accelerator pedal (see para. 60). As to claim 19, Naserian teaches the method of claim 17 further comprising applying regenerative braking at the dynamic regenerative braking level and prior to resetting the dynamic regenerative braking level by the electronic device (see para. 29 and 60). 3.
