The invention relates to a method for enhancing the slope-holding stability of a corner module distributed chassis, which comprises a chassis, a direction accelerator brake pedal assembly, a vehicle management unit VCU, a battery, a battery management unit and four corner modules arranged on the chassis, and comprises the following steps: S1, when the vehicle management unit VCU receives a brake signal, setting a target vehicle speed to be zero, the speed is compared with the actual speed in real time to form rotating speed closed-loop control of the vehicle; s2, the vehicle management unit VCU performs real-time adjustment until the vehicle speed is zero, then the acceleration of the vehicle is detected, and if the acceleration is not zero, the step S3 is performed; and S3, the vehicle management unit VCU sends a wheel turning angle control signal, and the included angle value of the left wheel and the right wheel needing to be controlled is input to four corner modules of the vehicle, so that the acceleration of the vehicle is zero. The method is easy and reliable to implement, and heat loss of motor stalling cannot be generated; the hill-holding load on a mechanical device is reduced, and the reliability of the system is further improved.

    本发明涉及一种增强角模块分布式底盘驻坡稳定性的方法,包括底盘、方向油门刹车踏板组件、车辆管理单元VCU、电池及电池管理单元以及设置在底盘上的四个角模块,步骤如下:S1、当车辆管理单元VCU接收到刹车信号时,将目标车速设定为零,并与实际车速实时比较,形成车辆的转速闭环控制;S2、车辆管理单元VCU实时调节,直至车速为零,然后对车辆的加速度进行检测,若加速度不为零则进行步骤S3;S3、车辆管理单元VCU发出的车轮转角控制信号,将需要控制的左右车轮的夹角值输入给车辆的四个角模块,使得车辆的加速度为零。本发明的方法实现简单可靠,不会产生电机堵转的热损耗;减少对机械装置的驻坡载荷,进一步提高了系统的可靠性。
