The invention provides a hill-holding control system and method, electronic equipment and a medium. In the control system provided by the invention, when the vehicle is in the hill-holding control mode and in the static state on the ramp, the current hill-holding torque of the vehicle is attenuated based on the preset attenuation rate. And when the motion state of the vehicle is changed into a non-static state, the attenuation process of the first hill-holding torque is stopped at the moment, and the first hill-holding torque is adjusted through a second hill-holding control module based on a preset vehicle speed control strategy to a second hill-holding torque capable of keeping the vehicle in the static state. At the moment, the upward static friction force of the vehicle along the ramp and the second hill-holding torque are jointly used for maintaining the static state of the vehicle on the ramp, so that the problem that when the vehicle is subjected to hill-holding control on the ramp, the parking torque of the vehicle is too large, so that the controller triggers overload or the locked-rotor power is reduced, and the vehicle sliding risk exists when the vehicle is started is effectively solved; and the safety of vehicle slope parking control is improved.

    本申请提供了一种驻坡控制系统、方法、电子设备及介质。在本申请提供的控制系统中,当车辆在坡道上处于驻坡控制模式且处于静止状态时,会基于预设衰减速率对车辆的当前驻坡扭矩进行衰减处理。当车辆的运动状态变为非静止状态时,此时会停止第一驻坡扭矩的衰减过程,并通过第二驻坡控制模块基于预设车速控制策略对第一驻坡扭矩进行调整,调整至能让车辆维持静止状态的的第二驻坡扭矩。此时车辆沿坡道向上的静摩擦力与第二驻坡扭矩共同用于维持车辆在坡道上的静止状态,从而有效避免车辆在坡道上进行驻坡控制时,其驻停扭矩过大使得控制器触发过载或堵转功率下降导致车辆在启动时存在溜车风险的问题,提高了车辆驻坡控制的安全性。
