The embodiment of the invention provides an automobile brake system and an automobile brake method. The brake system comprises a brake pedal device and a front wheel end brake system. The brake pedal device is connected with the front wheel end brake system through an electrical and pressure pipeline; the front wheel end braking system comprises a mechanical backup device and a braking execution device; the mechanical backup device comprises an axial driving device; the axial driving device is movably connected with the brake execution device; and the axial driving device is connected with the brake pedal device through a pressure pipeline. The mechanical backup device is additionally arranged in the front wheel end brake system, when an automobile has electrical failure, the brake pedal device is used for generating brake pressure, and the brake pressure is transmitted to the mechanical backup device through the pressure pipeline, so that the mechanical backup device is driven, and electronic auxiliary brake control or mechanical brake control is achieved. Compared with the prior art, an electronic and mechanical dual-backup device is added, so that the robustness of automatic driving and brake-by-wire of the whole vehicle and the safety and reliability of the whole vehicle are greatly improved.
本申请实施例提供了一种汽车制动系统及汽车制动方法,制动系统包括制动踏板装置和前轮轮端制动系统;制动踏板装置和前轮轮端制动系统通过电气、压力管道连接;前轮轮端制动系统包括机械备份装置和制动执行装置;机械备份装置包括轴向驱动装置;轴向驱动装置与制动执行装置活动连接;轴向驱动装置和制动踏板装置通过压力管道连接。通过在前轮轮端制动系统中增加了机械备份装置,在汽车存在电气失效时,利用制动踏板装置产生制动压力,通过压力管道传递至机械备份装置,从而驱动机械备份装置,实现电子辅助制动控制或者机械制动控制。与现有技术相比,增加电子与机械的双备份装置,大大提高整车自动驾驶、线控制动的鲁棒性与整车的安全可靠性。
