在汽車發動機起動時，若發動機起動后起動機不能及時斷電，將會燒毀起動機或損壞飛輪齒環；若變速器不在空檔位置起動，則起動機的瞬間動力將使汽車位移，還可能引起交通事故和人身安全。為此介紹一種利用NXP P89LPC901單片機控制的汽車起動保護控制器，通過檢測汽車起動開關、變速箱檔位、發動機轉速，實現對汽車發動機起動過程檢測和保護。起動保護控制器在發動機起動過程中通過采用逐個關閉打開負載系統，解決汽車發動機過程中因起動電流大而對汽車電源的沖擊影響,延長了電瓶壽命。
Abstract:
When the automotive engine is started, the engine start motor and flywheel gear may be damaged， even traffic accidents and personal safeties may be caused by wrong operation or other factors.In order to ensure the automotive engine can be started normally and safely,it is necessary that the protecting measures and methods are considered in the automotive electrical control system.This paper introduces a kind of the automotive engine starting protect controller based on NXP P89LPC901 MCU.The controller can protect the engine starting process by detecting the starter key switch,transmission stall and engine speed.Through the use of close and open load system,the controller can solve the impact on automotive power because of the high-current load in the process of the automobile engine starting, and extend battery life.
