The invention discloses a vehicle torque control method and system, a whole vehicle domain controller and a vehicle, and the method comprises the steps: detecting whether a torque request instruction sent by a chassis domain control module is received or not according to a bus transmission priority sequence in the process that the vehicle runs in an automatic driving mode; when the torque request instruction is not received, a communication fault identifier is sent to an ADAS domain control module, so that the ADAS domain control module responds to the communication fault identifier and feeds back a parking instruction; and when a parking instruction is received, the vehicle is controlled to exit the automatic driving mode, and a torque reduction instruction is sent to the motor, so that the motor responds to the torque reduction instruction, and the output torque is reduced. When the vehicle runs in the automatic driving mode and the torque request instruction sent by the chassis domain control module is not received, the vehicle can be controlled to quit the automatic driving mode in time, and the motor is controlled to reduce the output torque, so that the vehicle can stably decelerate until parking.
本发明公开一种车辆扭矩控制方法、系统、整车域控制器及车辆,该方法包括:在车辆运行自动驾驶模式的过程中,按照总线传输优先级顺序检测是否接收到底盘域控制模块发送的扭矩请求指令;当未接收到扭矩请求指令时,向ADAS域控制模块发送通讯故障标识,以使ADAS域控制模块响应通讯故障标识,反馈停车指令;当接收到停车指令时,控制车辆退出自动驾驶模式,并向电机发送扭矩降低指令,以使电机响应扭矩降低指令,降低输出扭矩。本发明在车辆运行自动驾驶模式的过程中,且未接收到底盘域控制模块发送的扭矩请求指令时,能够及时控制车辆退出自动驾驶模式,并控制电机降低输出扭矩,从而使得车辆能够平稳减速,直至停车。
