本發明涉(she)及(ji)(ji)制(zhi)動控制(zhi),具體涉(she)及(ji)(ji)一種應用(yong)于駐(zhu)車制(zhi)動的備份制(zhi)動電(dian)路及(ji)(ji)其(qi)制(zhi)動方(fang)法。
背景技術:
1、駐(zhu)車(che)(che)制(zhi)動(dong)(dong)失效(xiao)指的(de)是車(che)(che)輛的(de)駐(zhu)車(che)(che)制(zhi)動(dong)(dong)系統失去或部分失去了其應有的(de)制(zhi)動(dong)(dong)效(xiao)能(neng),這可能(neng)導致車(che)(che)輛在靜止(zhi)時無(wu)法保(bao)持穩定(ding),尤其是在斜坡上。駐(zhu)車(che)(che)制(zhi)動(dong)(dong)系統通(tong)常包括手(shou)剎(手(shou)動(dong)(dong)駐(zhu)車(che)(che)制(zhi)動(dong)(dong)器)或腳踏式駐(zhu)車(che)(che)制(zhi)動(dong)(dong)器,以及現代汽(qi)車(che)(che)中越來越多見的(de)電子駐(zhu)車(che)(che)制(zhi)動(dong)(dong)器(epb)。
2、ecu(電子控制(zhi)(zhi)(zhi)單元(yuan))在現代汽車(che)(che)中扮(ban)演著至(zhi)關重要的(de)(de)角色,尤其是對(dui)于那些采用電子駐(zhu)車(che)(che)制(zhi)(zhi)(zhi)動(dong)系(xi)統(epb,electrical?park?brake)的(de)(de)車(che)(che)輛。電子駐(zhu)車(che)(che)制(zhi)(zhi)(zhi)動(dong)系(xi)統依賴于ecu來控制(zhi)(zhi)(zhi)制(zhi)(zhi)(zhi)動(dong)卡鉗(qian)的(de)(de)電動(dong)馬達或電磁裝置,從而實現駐(zhu)車(che)(che)制(zhi)(zhi)(zhi)動(dong)功能。如果ecu失(shi)效,這將對(dui)車(che)(che)輛的(de)(de)駐(zhu)車(che)(che)制(zhi)(zhi)(zhi)動(dong)功能產生直接且嚴(yan)重的(de)(de)影響(xiang)。因此,如何在ecu失(shi)效的(de)(de)情況下緊(jin)急對(dui)車(che)(che)輛進行駐(zhu)車(che)(che)制(zhi)(zhi)(zhi)動(dong),避(bi)免次生危害(hai)的(de)(de)產生,就是本方案所(suo)需要解決的(de)(de)技(ji)術問題(ti)。
