摘要
为提高汽车电动助力转向系统(EPS)的可靠性与故障容错性,提出了将闪存应用到EPS电动助力转向系统中,以提高EPS助力系统可靠性的问题。传感器正常工作时,在闪存中存储了汽车运行状态的传感器数据;传感器失效时,则从闪存中的数据库中得出与当前汽车运行状态相近的数据,提供给ECU,实现EPS系统性能不因传感器失效而丢失,以此提高EPS系统的可靠性。
To enhance the reliability and Malfunction Concession of Electric Power Steering System, bring forward the Flash Memory into Electric Power Steering System, The programme store the dada into Flash Memory when all sensors are normal. The Flash Memory supply the analogical data when some sensors are malfunction, offer to the ECU. Make the Electric Power Steering System still work as some sensors are malfunction, to enhance the reliability of EPS system.
