The invention relates to a parking control method and device, vehicle-mounted equipment and a vehicle. According to the method, the vehicle speed and the caliper state are obtained, if the vehicle speed is smaller than a static judgment threshold value and the caliper state is a clamping state, timing is started, the timing result is compared with the preset parking duration, and if the timing result is larger than the preset parking duration, the parking control is started. If yes, the wheel speed pulse of the wheel is calculated so as to judge that the vehicle slides according to the calculation result, the control motor is triggered to change the caliper state into the re-clamping state, and the working state of the control motor is controlled according to the working time when the control motor enters the load applying stage; the problem of inaccurate wheel speed pulse detection caused by poor robustness of a wheel speed sensor in working conditions such as the initial stage of vehicle electrification can be avoided, and the accuracy of vehicle sliding judgment is improved, so that a sliding slope re-clamping function is effectively prevented from being triggered by mistake, and the situation that due to the fact that the sliding slope re-clamping function is triggered by mistake, a motor transiently acts, and the service life of the vehicle is prolonged is reduced. And harsh noise is generated.
本发明涉及一种驻车控制方法、装置、车载设备及车辆,该方法通过获取车辆速度和卡钳状态,若车辆速度小于静止判断阈值且卡钳状态为夹紧状态,则启动计时,并将计时结果与预设驻车时长进行比较,若计时结果大于预设驻车时长,则计算车轮的轮速脉冲,以根据计算结果判定车辆溜车,并触发控制电机将卡钳状态变为再次夹紧状态,根据控制电机进入载荷施加阶段的工作时间控制控制电机的工作状态;本发明不仅可以避免车辆上电初期等工况时轮速传感器鲁棒性差,导致车轮的轮速脉冲检测不准确的问题,提高车辆溜车判定的准确性,从而有效防止误触发溜坡再夹紧功能,减少由于误触发溜坡再夹紧功能导致电机短暂动作,产生刺耳噪声的情形。
