The invention provides an uphill vehicle launch in a single pedal driving mode. A vehicle includes: a powertrain having an electric machine configured to provide power to a driven wheel; and a friction brake. A vehicle controller is programmed to, while the vehicle is in a single pedal driving mode and the friction brake is automatically engaged to maintain the vehicle stationary, in response to an estimated torque of the driven wheel exceeding a grade compensation torque threshold based on a road grade. The friction brake is released without input from a brake pedal to launch the vehicle without rollback.

    本公开提供了“单踏板驾驶模式下的上坡车辆起步”。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;以及摩擦制动器。车辆控制器被编程为在所述车辆处于单踏板驾驶模式并且所述摩擦制动器自动地接合以保持所述车辆静止的情况下,响应于所述从动轮的估计扭矩超过基于道路坡度的坡度补偿扭矩阈值,在没有来自制动踏板的输入的情况下释放所述摩擦制动器,以在没有回滚的情况下使所述车辆起步。
