Abstract

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.

Description

technical field [0001] The invention relates to the field of automobile electronic information, in particular to a vehicle power distribution method, system and automobile. Background technique [0002] With the progress of society, various practical electronic modules in automobiles have been developed. Each electronic module has a corresponding controller, and all controllers are uniformly controlled by the driving computer. [0003] There are many electronic modules on the car. Due to the error or disorder of the electronic module program on the car, the electronic module may sleep abnormally after the car is powered off. The electronic module will keep working normally for a long time. The abnormal sleep of the electronic module will consume a certain amount of battery power. In the case of continuous output of the battery, the low battery power will cause the battery to lose power, which will make it difficult to start the car the next time it is started.
