The invention discloses a vehicle body control system and method matched with different wire diameters. The vehicle body control system comprises a storage battery, a vehicle body controller and a load. Wherein the storage battery is connected with the vehicle body controller, and the vehicle body controller is connected with the load; a vehicle body control module and a current detection element are arranged in the vehicle body controller, the vehicle body control module is used for distributing power to a load and detecting the current value of the load during working, and when the current value of the load during working exceeds a set threshold value, the load is judged to be short-circuited, and then the current detection element is controlled to be disconnected with the storage battery. According to the invention, a semiconductor device is matched with software to realize power distribution of the load, relatively accurate sampling of the load current, current sampling with the precision of 1-15%, improvement of the current sampling precision and more accurate control and management of the load current, so that the short-circuit current of the wire harness can reserve a safety margin smaller than that of a traditional mode, and the safety of the wire harness is improved. And a smaller and more appropriate load wire diameter is selected on the wire diameter.

    本发明公开了一种匹配不同线径的车身控制系统及方法,包括电瓶、车身控制器和负载;其中,电瓶与车身控制器相连,车身控制器与负载相连;在车身控制器内设有车身控制模块和电流检测元件,车身控制模块用于对负载进行配电,并检测负载工作时的电流值,当负载工作时的电流值超过设定阈值时,则将其判定为短路,然后控制电流检测元件断开与电瓶的连接。本发明采用半导体器件与软件相配合,实现对负载的配电,并对负载电流的相对精确采样,实现精度1%~15%的电流采样,提高电流采样的精度,对负载电流进行更精确的控制和管理,这样线束的短路电流就可以预留比传统方式更小的安全裕量,体现在线径上选择更小更合适的负载线径。
