The invention provides a hydraulic control system, a control method thereof, and a vehicle. The hydraulic control system comprises an oil pump, a first oil cylinder connected to the oil pump and a motor used for driving the oil pump to supply oil to the first oil cylinder, and a telescopic rod of the first oil cylinder is connected to the first load part. The hydraulic control system further comprises a controller connected to the motor and a buffer switch connected to the controller, the controller is used for controlling the motor, and the buffer switch is used for generating a buffer signal and sending the buffer signal to the controller when the telescopic rod of the first oil cylinder drives the first load part to move to a preset stroke in the extending direction. And the controller controls the motor to reduce from the first rotating speed to the second rotating speed based on the buffer signal, so that the telescopic rod of the first oil cylinder drives the first load piece to move at the second speed from the first speed. In the invention, the controller controls the motor to reduce the rotating speed and even stop slowly based on the buffer signal, so that the impact generated by inertia when the mechanical stroke of the first oil cylinder reaches the bottom can be eliminated, and the first load piece is prevented from shaking.

    本发明提供液压控制系统及其控制方法、以及车辆。该液压控制系统包括油泵、连接于油泵的第一油缸以及用于驱动油泵给第一油缸供油的电机,第一油缸的伸缩杆连接于第一负载件。液压控制系统还包括连接于电机的控制器及连接于控制器的缓冲开关,控制器用于控制电机,缓冲开关用于在第一油缸的伸缩杆带动第一负载件沿伸出方向移动至预设行程时生成缓冲信号并发送至控制器;控制器基于缓冲信号控制电机由第一转速减小至第二转速,使得第一油缸的伸缩杆带动第一负载件移动的速度由第一速度减小至第二速度。本发明中,控制器基于缓冲信号控制电机的转速减小甚至缓慢停下来,可以消除第一油缸机械行程到底时因惯性产生的冲击,防止第一负载件发生晃动。
