The invention relates to the technical field of vehicle brake control, and provides a vehicle brake anti-nodding system and a control method.The vehicle brake anti-nodding system comprises a virtual quantity brake pedal connected to an actual brake pedal of a vehicle and used for obtaining the brake opening degree of the actual brake pedal and sending the brake opening degree to an ESC brake control module; the electronic dampers are arranged in front wheels and rear wheels of the vehicle, the compression and rebound speed adjustment of the dampers is achieved by changing the opening degree of the flow suppression valve, and therefore damping force is provided for the wheels; the ESC brake control module is integrated with a built-in acceleration sensor and is configured to execute the brake control method, receive the brake opening degree of the virtual quantity brake pedal and control the opening degree of a flow suppression valve of the electronic damper according to the vehicle body state monitored by the built-in acceleration sensor and the acceleration value of the vehicle. According to the invention, automatic stable control of the vehicle body during braking of the passenger car is realized, the phenomena of nodding and shaking of the vehicle body during braking of the passenger car are solved, and good braking stability and riding comfort are ensured.
本公开涉及车辆制动控制技术领域,提出了一种车辆用刹车防点头系统及控制方法,包括虚拟量制动踏板,连接至车辆的实际制动踏板,用于获取实际制动踏板的制动开度并发送至ESC制动控制模块;电子阻尼器,设置在车辆前轮和后轮内,通过改变抑流阀开度实现阻尼器的压缩和回弹速度调整,从而为车轮提供阻尼力;ESC制动控制模块集成内置加速度传感器,被配置为执行制动控制方法,接收虚拟量制动踏板的制动开度,根据内置加速度传感器监测的车身状态以及车辆的加速度值,控制电子阻尼器的抑流阀开度。本公开实现客车制动时车身的自动稳定控制,解决客车制动时车身出现点头和车身晃动的现象,保证良好的制动稳定性和乘坐舒适性。
