The embodiment of the invention discloses an automobile torque control method and system. The automobile torque control method comprises the steps that whether a driver has a driving demand or not is judged; when the driver does not have the driving requirement, the whole vehicle control assembly executes sliding energy recovery; when a driver has a braking demand, the integrated braking control system obtains braking energy recovery torque according to the brake pedal stroke and sends the braking energy recovery torque to the whole vehicle control assembly; the whole vehicle control assembly recovers braking energy; when the vehicle is in a locked state, the integrated brake control system sends a torque rising request value to the whole vehicle control assembly; the whole vehicle control assembly controls the output torque to be increased by the torque increasing request value until the locking state is stopped; the torque-up request value is the sum of the engine torque control torque and the braking energy recovery torque. By means of the method, the locking problem of the vehicle can be rapidly solved, the sliding energy recovery efficiency and the braking energy recovery efficiency are improved, and the comfort level, the stability and the safety of vehicle longitudinal control are improved.

    本发明实施例公开了一种汽车扭矩控制方法及系统,该汽车扭矩控制方法包括:判断驾驶员是否有驱动需求;当驾驶员无驱动需求时,整车控制总成执行滑行能量回收;当驾驶员有制动需求时,集成式制动控制系统根据刹车踏板行程获取制动能量回收扭矩并发送至整车控制总成;整车控制总成进行制动能量回收;当车辆出现抱死状态时,集成式制动控制系统发送升扭请求值至整车控制总成;整车控制总成控制输出扭矩提升升扭请求值,直至抱死状态停止;升扭请求值为发动机转矩控制扭矩与制动能量回收扭矩的加和。利用上述方法,可以快速消除车辆的抱死问题,提高了滑行能量回收和制动能量回收的效率,提升了车辆纵向控制的舒适度、稳定性及安全性。
