The invention is suitable for the technical field of automobile stability control systems, and provides a commercial vehicle stability control system which comprises an MCU central processor unit, a signal acquisition part, a power supply part, a communication part and a driving part. According to the stability control system for the commercial vehicle, the MCU central processor unit, the signal acquisition part, the power supply part, the communication part and the driving part are arranged, the system establishes a vehicle dynamics model and estimates the vehicle posture through data such as a gyroscope sensor and a wheel speed signal, and when the vehicle is about to have dangerous understeering, oversteering or rollover working conditions, the vehicle can be driven to move back and forth. Torque control is carried out on an engine, braking control is carried out on one or more wheels, the posture of the vehicle is corrected, and load output is controlled, so that the effects of good anti-lock smoothness and short braking distance are achieved, in the braking process, the vehicle speed is reduced stably, the deceleration fluctuation is small, and the braking distance becomes shorter; therefore, the overall safety performance of the vehicle in the running process is improved.
本发明适用于汽车稳定性控制系统技术领域,提供了一种商用车稳定性控制系统,包括MCU中央处理器单元、信号采集部分、电源部分、通信部分和驱动部分。该商用车稳定性控制系统,通过设置MCU中央处理器单元、信号采集部分、电源部分、通信部分和驱动部分,系统通过陀螺仪传感器和轮速信号等数据,建立车辆动力学模型,预估车辆姿态,当车辆即将出现危险的转向不足、转向过度或者侧翻工况时,对发动机实施扭矩控制,对某个或者多个车轮实施制动控制,纠正车辆姿态,控制负载输出,从而达到防抱死平顺性好,制动距离短的效果,并且在制动过程中,车速下降平稳,减速度波动小,制动距离也会变得更短,从而提高车辆行驶过程中的整体安全性能。
