The invention relates to an automatic transmission vehicle and a slope starting auxiliary device and method for the automatic transmission vehicle, and the method comprises the following steps: S1, a vehicle speed sensor collects a vehicle speed signal and sends the vehicle speed signal to a CAN network, and a gearbox TCU recognizes the state of the vehicle according to the vehicle speed signal and judges whether slope starting needs to be carried out or not; s2, if hill starting needs to be carried out, a brake pedal provides brake pre-relieving signal data to the CAN network; the gearbox TCU reads braking pre-relieving signal data from the CAN network, and slope resistance logic judgment of the wheel edge driving force and the gravity downward along the slope face is carried out; s3, after the logic judgment in the step S2 is met, the gearbox TCU controls an electric control clutch to be in a semi-linkage state to transmit torque to a wheel edge, and meanwhile, braking releasing signal data are sent to an ABS controller; and S4, after the ABS controller receives the brake release signal data, the parking electromagnetic valve is controlled to release the wheel side brake force, and ramp starting is completed.

    本发明涉及一种自动挡车辆及自动挡车辆坡起辅助装置和方法,所述的方法包括以下步骤:步骤S1:车速传感器采集车速信号发送至CAN网络,变速箱TCU据此识别车辆状态,判断是否需进行坡道起步;步骤S2:如需进行坡道起步,制动踏板提供制动预解除信号数据至所述CAN网络;变速箱TCU从CAN网络上读取制动预解除信号数据,进行所述轮边驱动力与重力沿斜坡面向下的坡道阻力逻辑判断;步骤S3:符合步骤S2中的逻辑判断后,变速箱TCU控制电控离合器处于半联动状态向轮边传递扭矩,同时向ABS控制器发送制动解除信号数据;步骤S4:ABS控制器接收到制动解除信号数据后,控制停车电磁阀解除轮边制动力坡道起步完成。
