The invention provides a longitudinal control method of a vehicle, a torque controller and the vehicle, and the longitudinal control method comprises the steps: receiving a target acceleration sent by an ADAS when a VLC function in the torque controller is in an activated state; determining a wheel end demand torque of the vehicle according to the target acceleration; according to the wheel end demand torque and a preset torque distribution condition, a motor demand torque and an auxiliary braking demand torque are determined; and the motor demand torque is sent to the motor, and/or the auxiliary braking demand torque is sent to the auxiliary braking mechanism. The VLC function is integrated in the torque controller, so that the torque controller can calculate and distribute the torque, the target acceleration only needs to be received from the ADAS, torque switching between the ADAS and the torque controller is avoided, and the drivability of the whole vehicle is improved.
本申请提供了一种车辆的纵向控制方法、扭矩控制器及车辆,其中纵向控制方法包括:在扭矩控制器中的VLC功能处于激活状态时,接收ADAS发送的目标加速度;根据目标加速度,确定车辆的轮端需求扭矩;根据轮端需求扭矩以及预设扭矩分配条件,确定电机需求扭矩和辅助制动需求扭矩;将电机需求扭矩发送至电机,和/或将辅助制动需扭矩发送至辅助制动机构。本申请通过将VLC功能集成于扭矩控制器中,使得扭矩控制器可进行扭矩计算和分配,从而仅需要从ADAS中接收目标加速度,避免了ADAS和扭矩控制器之间的扭矩切换,进而有利于提高整车的驾驶性。
