The invention provides a vehicle power distribution method, a system and a vehicle, and relates to the field of vehicle electronic information.The vehicle power distribution method comprises the steps that when a vehicle is in a power-off state, first-time countdown is started within a first preset time period, and whether message transmission exists on a bus or not is traversed after the first-time countdown is finished; if yes, according to the type of the message, determining that at least one electronic module is abnormal in dormancy to cause that a bus is not dormant; and the fault information of the electronic module is recorded, and the power distribution gateway controls the electronic module to be powered off, so that the bus enters a dormant state. The technical problems that in the prior art, abnormal dormancy of the electronic module consumes electric quantity of the storage battery, and the vehicle is difficult to start next time due to insufficient electricity of the storage battery can be solved.
本发明提供一种车辆配电方法、系统及汽车,涉及汽车电子信息领域,该车辆配电方法包括:在车辆处于下电状态时,以第一预设时间段开始第一次倒计时,在第一次倒计时结束后遍历总线上是否有报文传输;若是,根据所述报文的类型确定至少存在一电子模块休眠异常以导致总线不休眠;记录所述电子模块的故障信息,所述配电网关控制所述电子模块断电,以使所述总线进入休眠状态。本发明能够解决现有技术中电子模块休眠异常将耗费蓄电池电量,蓄电池亏电导致汽车下一次启动困难的技术问题。
