The invention discloses a multi-mode electronic hydraulic brake boosting system and a control method. When the power assisting system fails, an emergency mechanical braking mode is achieved through structural redundancy, under the normal power assisting mode, common braking and emergency braking are divided according to the strength requirement of a brake, and the common braking power assisting mode and the emergency active pressurizing mode are controlled respectively. Accurate assistance can be provided during general braking so that the pressure of the brake master cylinder can accurately follow the target pressure, pressure buildup of the brake master cylinder can be completed more quickly during emergency braking, braking force is output to the maximum extent, the system response timeof the emergency braking working condition is shortened, the braking capacity is improved, and traffic accidents are avoided. The design of the multi-mode power assisting system can accurately trackthe braking intention of a driver, the intelligent degree of switching between different power assisting modes is high, the rapidity and accuracy of braking response and the safety of a vehicle are improved, and the multi-mode power assisting system has very high practical application value.

    本发明公开了一种多模式电子液压制动器助力系统及控制方法,在助力系统失效时通过结构冗余实现应急机械制动模式,正常助力模式下根据制动器强度需求分为一般制动和紧急制动,分别进行一般制动助力模式和紧急主动增压模式控制;一般制动时能够提供准确的助力使制动主缸压力精确跟随目标压力,紧急制动时能够更快的完成制动主缸建压,最大程度的输出制动力,减少紧急制动工况的系统反应时间,提升制动能力,避免交通事故。多模式助力系统设计能够准确的跟踪驾驶员制动意图,不同助力模式切换智能化程度高,提升了制动响应的快速性、准确性和车辆安全性,具有很高的实际应用价值。
