In order to improve the performance of Body Control Module (BCM) for economy cars,the specialized automotive controller (MC9S08AW32) which has strong ability of anti-electromagnetic interference is used into BCM design.The SCADE software is introduced into the control logic applications.With remote control and anti-burglar through RKE (Remote Keyless Entry) technology,a low-cost high performance centralized BCM design is presented.The real application and test in economy cars verifies the reliable performance with preferable cost of the proposed BCM system.
