The invention discloses a redundancy control method for a brake-by-wire system. The redundancy control method comprises the following conditions: S1, normal braking-redundancy control is not started; S2, a redundancy control working condition-EHB displacement sensor has a fault; S3, the redundancy control working condition-EHB pressure sensor has a fault; from the perspective of a brake system, the invention provides a redundancy control method, that is, aiming at various failure conditions of the EHB, different post-processing strategies are formulated, the active pressurization function of the ESC is called, and the brake performance is improved; the method can be realized without replacing or adding extra hardware equipment, and no extra cost is increased.

    本发明公开了一种用于线控制动系统的冗余控制方法,包括以下情况:S1正常制动‑冗余控制不启用,S2冗余控制工况‑EHB位移传感器故障,S3冗余控制工况‑EHB压力传感器故障,S4冗余控制工况‑EHB助力电机故障,S5冗余控制工况‑EHB建压异常。本发明从制动系统角度,提出一种冗余控制方法,即针对EHB的各种失效情况,制定不同的后处理策略,调用ESC的主动增压功能,改善制动性能;本发明不需要更换或增加额外的硬件设备即可实现,没有额外的成本增加。
