The invention relates to a vehicle control method and a vehicle control unit of a vehicle. The vehicle control method is used for controlling start or stop of a vehicle power module and a brake energy regeneration system based on signals of a sensor, the vehicle power module provides power for a vacuum pump of a vacuum booster of a vehicle, and the vehicle control method comprises the steps that step one, a detection signal of brake torque is obtained, whether the vehicle is in a brake state or not is judged; if so, subsequent steps are continued; step two, judging whether the vehicle is in a stopped state or a moving state; step three, if the vehicle is in the stop state in the step two, whether enough vacuum exists in the vacuum booster or not is judged according to the obtained braking torque; and a first control step is executed: a control signal for controlling the state of the vehicle power module is outputted according to the judgment result of the step three, so that the engine stops running or runs.

    本发明涉及一种车辆的车辆控制方法和车辆控制单元。车辆控制方法,用以基于传感器的信号控制车辆动力模块和制动能量再生系统的启停,其中车辆动力模块为车辆的真空助力器的真空泵提供动力,包括:第一步骤,获取制动扭矩的检测信号,判断车辆是否处于制动状态,若判断车辆处于制动状态,则继续后续步骤;第二步骤,判断车辆是处于停止状态还是运动状态;第三步骤,若所述第二步骤中判断为车辆处于停止状态,则根据所获取的制动扭矩大小,来判断真空助力器中是否存有足够的真空度;以及,第一控制步骤,根据所述第三步骤的判断结果,输出用于控制车辆动力模块状态的控制信号,使发动机停止运行或运行。
