VEHICLE CONTROL DEVICE
20230098578 · 2023-03-30 ·

A control device for a vehicle is provided, which includes a power source that generates torque for driving or braking the vehicle, an accelerator pedal sensor that detects an operating amount of an accelerator pedal, and a control unit that controls the power source. The control unit sets a target acceleration based on the accelerator pedal operating amount detected by the accelerator pedal sensor. The control unit sets a target jerk based on the target acceleration, and when the target acceleration decreases toward 0 from a value above 0, sets the target jerk so that an absolute value of the target jerk becomes smaller as the target acceleration approaches 0. The control unit sets torque to be outputted or regenerated by the power source, based on the target acceleration and the target jerk.

20220348087 · 2022-11-03 ·

Braking of a vehicle and a trailer can be balanced when regenerative braking of the vehicle is activated. The activation of regenerative braking of the vehicle can be detected. Responsive to detecting that regenerative braking of the vehicle is activated, one or more brakes of the trailer can be caused to be activated. Thus, the braking effectiveness of the vehicle and the braking effectiveness of the trailer can be substantially balanced. As a result, a possible push force from a trailer to the vehicle towing the trailer can be reduced, which, in turn, can help to avoid unwanted movements of the trailer (e.g., swaying or jackknifing).
