The invention discloses a redundant brake pedal stroke signal implementation method and system, and relates to the field of double-loop air pressure braking, the method comprises the following steps:establishing a corresponding relation between air pressure of an air outlet of an electric control foot brake valve and a brake pedal stroke, and generating a relation mapping table; acquiring the airpressure of an air outlet of the current electric control foot brake valve, and inquiring the relation mapping table to obtain the current brake pedal stroke; generating a brake pedal stroke signal based on the obtained current brake pedal stroke; and sending the generated brake pedal travel signal to a brake execution system. Vehicle driving safety can be effectively guaranteed.
本发明公开了一种冗余制动踏板行程信号实现方法及系统,涉及双回路气压制动领域,该方法包括建立电控脚制动阀出气口气压与制动踏板行程之间的对应关系,并生成关系映射表;获取当前电控脚制动阀出气口的气压,查询关系映射表,得到当前制动踏板行程;基于得到的当前制动踏板行程,生成制动踏板行程信号;将生成的制动踏板行程信号发送给制动执行系统。本发明能够有效保证车辆行驶安全。
