The present disclosure provides for aggregating braking torque during a single pedal driving mode. A vehicle includes: a powertrain having an electric machine configured to provide power to a driven wheel; an accelerator pedal; and a friction brake. The vehicle controller is programmed to, with the vehicle in a single pedal driving mode, command a torque from the powertrain equal to a target braking torque based on a position of an accelerator pedal in response to a braking torque capacity of the powertrain exceeding the target braking torque, such that the vehicle is decelerated using the powertrain without applying the friction brake; and in response to the braking torque capacity of the powertrain being less than the target braking torque, commanding torque from the powertrain and the friction brake such that the target braking torque is satisfied and the vehicle is decelerated using the powertrain and the friction brake.
本公开提供“在单踏板驾驶模式期间聚合制动转矩”。一种车辆包括:动力传动系统,所述动力传动系统具有被配置为向从动轮提供动力的电机;加速踏板;以及摩擦制动器。车辆控制器被编程为在车辆处于单踏板驾驶模式的情况下:响应于动力传动系统的制动转矩容量超过基于加速踏板的位置的目标制动转矩,命令来自动力传动系统的等于所述目标制动转矩的转矩,使得在不应用所述摩擦制动器的情况下使用所述动力传动系统使所述车辆减速;并且响应于所述动力传动系统的所述制动转矩容量小于所述目标制动转矩,命令来自所述动力传动系统和所述摩擦制动器的转矩,使得满足所述目标制动转矩并且使用所述动力传动系统和所述摩擦制动器使所述车辆减速。
