The invention provides a vehicle control method and system. The method comprises the steps that a vehicle body electronic stabilization system on a target vehicle obtains the whole vehicle speed and transverse acceleration information of the target vehicle; the vehicle body electronic stabilization system determines the current motion working condition of the target vehicle according to the whole vehicle speed and the transverse acceleration information; when the current motion working condition is the low-dynamic working condition and a motor controller on the target vehicle detects that the target vehicle slips, torque reduction control is carried out to restrain slipping of the target vehicle; when the current motion working condition is the high-dynamic working condition, a vehicle control unit on the target vehicle obtains torque required by a driver and ESP torque reduction torque calculated by a vehicle body electronic stability system; and corresponding control operation is carried out according to the driver demand torque and the ESP torque reduction torque. Therefore, the method and the device can reduce the response delay, so that the rapidity of torque response is improved, and the slip degree of the vehicle is reduced.
本申请提供一种车辆控制方法及系统,该方法包括:目标车辆上的车身电子稳定系统获取目标车辆的整车车速和横向加速度信息;车身电子稳定系统根据整车车速和横向加速度信息,确定目标车辆的当前运动工况;当当前运动工况为低动态工况时,目标车辆上的电机控制器在检测到目标车辆打滑时,进行降扭控制,以抑制目标车辆的打滑;当当前运动工况为高动态工况时,目标车辆上的整车控制器获取驾驶员需求扭矩和车身电子稳定系统计算的ESP降扭扭矩;以及根据驾驶员需求扭矩和ESP降扭扭矩进行相应的控制操作。可见,该方法及装置能够降低响应延迟,从而提高扭矩响应的快速性,减少车辆打滑程度。
