The invention discloses a method for achieving slope sliding and re-clamping of an electronic parking system, and the method comprises a vehicle slope sliding judgment logic and a slope sliding and re-clamping execution logic. The vehicle slope sliding judgment logic comprises vehicle slope sliding judgment, whether the EPB is in a clamping state or not, whether the vehicle has a driving-away intention, a rear wheel speed pulse exceeds a limit value, whether the voltage is normal, and whether the ECU is awakened. Whether the vehicle slips on the slope is judged by monitoring pulse signals of the wheel speed sensor, if the vehicle slips on the slope, the vehicle slips on the slope and then is clamped in time through a parking braking force compensation strategy, the vehicle is prevented from slipping on the slope, and safety is ensured.
本发明公开了一种电子驻车系统实现溜坡再夹紧的方法,所述方法包括车辆溜坡判断逻辑与执行溜坡再夹紧逻辑,所述车辆溜坡判断逻辑包括车辆溜坡判断、EPB是否夹紧状态、车辆是否有驶离意图、后轮速脉冲超过限值、电压是否正常、ECU是否唤醒、结束。本发明通过监测轮速传感器脉冲信号,对车辆是否溜坡进行判断,如发现溜坡,通过驻车制动力的补偿策略及时进行溜坡再夹紧,阻止车辆溜坡确保安全。
