The invention discloses a control method of a vehicle, an overcurrent detection system of a vehicle battery and the vehicle. The method comprises the steps that bus current of the battery of the vehicle is acquired; the branch current of each electric appliance in a plurality of electric appliances powered by the battery is obtained, and the branch current of each electric appliance is a branch current of the bus current; and judging whether the battery is over-current or not based on the bus current and the branch current of each electric appliance so as to obtain an over-current detection result, and controlling the vehicle according to the over-current detection result. According to the invention, the technical problem of low over-current detection accuracy of the battery is solved.
本发明公开了一种车辆的控制方法、车辆电池的过流检测系统及车辆,该方法包括:获取车辆的电池的母线电流;获取由电池供电的多个用电器中每个用电器的支线电流,其中,每个用电器的支线电流为母线电流的一个分支电流;基于母线电流和每个用电器的支线电流判断电池是否过流,以得到过流检测结果,并根据过流检测结果控制车辆。通过本发明解决了电池的过流检测准确性低的技术问题。
