Abstract
本发明涉及车辆控制系统技术领域,特别涉及一种大坡道攀爬防溜的控制方法、装置、存储介质及车辆,其中,方法包括:根据实际坡度计算松开油门时车辆即将停止后所需要的驻车力矩;根据驻车力矩计算电机所需堵转力矩;获取当前车辆滚动趋势,并根据其和预设门限值计算补偿力矩;根据驻车力矩、堵转力矩和补偿力矩辅助车辆在坡道上平稳驶离;在电机温度处于预设状况下,向驾驶员发出故障提醒和接管请求,并向制动控制器发出液压补偿指令,以辅助车辆在预设状况下的紧急临时驻车、电机恢复正常之前的液压制动、坡道行驶中静止并平稳驶离。由此,解决了相关技术中的坡中短暂停车并驶离存在驻车力矩不足、过热后的功能安全失效、反复频繁需要切换踏板等问题。

The invention relates to the technical field of vehicle control systems, in particular to a control method, a device, a storage medium and a vehicle for climbing and anti-slip on a large ramp, wherein the method comprises the steps of calculating parking torque required by the vehicle when an accelerator is released and the vehicle is about to stop according to an actual gradient; the method comprises the steps of calculating a required locked rotor torque of a motor according to a parking torque, obtaining a current rolling trend of the vehicle, calculating a compensation torque according to the current rolling trend and a preset threshold value, assisting the vehicle to stably drive away on a slope according to the parking torque, the locked rotor torque and the compensation torque, sending a fault reminding and taking over request to a driver when the temperature of the motor is in a preset condition, and sending a hydraulic compensation command to a brake controller so as to assist the emergency temporary parking of the vehicle under the preset condition, hydraulic braking before the motor returns to normal, and stationary and stable driving away in the slope driving. Therefore, the problems of insufficient parking torque, functional safety failure after overheat, repeated frequent pedal switching and the like existing in short parking and driving away in a slope in the related technology are solved.
