The invention provides a PEPS system and a communication method thereof, a vehicle body controller and a vehicle body control method. Before, the vehicle body controller wakes up the whole external CAN network, whether the external CAN network is awakened or not is determined through pre-judged premise information (namely the state information (effective or invalid) of an intelligent key close toa zone bit), so that the network where the whole BCM is located is not awakened under the abnormal false triggering working condition (namely approaching of the intelligent key to the zone bit is invalid), and the standby power consumption of a whole vehicle system is reduced.
本发明提供了一种PEPS系统及其通讯方法、车身控制器及车身控制方法,车身控制器唤醒整个外部CAN网络之前,通过预判的前提信息(即智能钥匙靠近标志位的状态信息(有效或无效)),来决定是否唤醒外部CAN网络,从而实现在异常误触发的工况下(即智能钥匙靠近标志位无效)不会唤醒整个BCM所在网络,从而降低整车系统的的待机功耗。
