The present disclosure provides "Single Pedal Driving Filtering and Rate Limiting of Powertrain Torque". A vehicle includes: a powertrain having an electric machine configured to provide power to a driven wheel; an accelerator pedal; and a brake pedal. The controller is programmed to: selectively brake the vehicle via operation of the electric machine in response to a torque required by a driver corresponding to a position of the accelerator pedal; further in response to a speed of the vehicle being greater than a threshold, limiting a rate of change of the driver-requested torque commanded to the powertrain based on a first rate limit; and further in response to the speed being less than another threshold, limiting a rate of change of the driver-requested torque commanded to the powertrain based on a second rate limit that is higher than the first rate limit such that for a given driver-requested torque, the speed is less than the other threshold. Acceleration and deceleration of the vehicle are more sensitive than when the first rate limit is applied.
本公开提供了“动力传动系统扭矩的单踏板驾驶滤波和速率限制”。一种车辆包括:动力传动系统,其具有被配置成向从动轮提供动力的电机;加速踏板;以及制动踏板。控制器被编程为:响应于与所述加速踏板的位置相对应的驾驶员要求的扭矩,经由所述电机的操作选择性地制动所述车辆;进一步响应于所述车辆的速度大于阈值,基于第一速率限制来限制向所述动力传动系统命令的所述驾驶员要求的扭矩的变化率;并且进一步响应于所述速度小于另一阈值,基于高于所述第一速率限制的第二速率限制来限制向所述动力传动系统命令的所述驾驶员要求的扭矩的变化率,使得对于给定的驾驶员要求的扭矩,所述车辆的加速和减速比施加所述第一速率限制时更灵敏。
