The invention provides a power supply control method and device for a vehicle body controller and a power-saving control circuit, relates to the field of vehicle power supply, and can solve the problem of how to enable the vehicle body controller to carry out effective energy-saving control on power supply through a specific circuit when a vehicle is switched between a sleep mode and a driving mode. Comprises: determining whether a vehicle body controller has a load power supply demand; under the condition that it is determined that the vehicle body controller has the load power supply requirement, a circuit between a whole vehicle power inlet port and a power supply port is controlled to be in a conducting state according to the power-saving control circuit, and a circuit between the whole vehicle power inlet port and a grounding port is controlled to be in a conducting state; and under the condition of determining that the vehicle body controller does not have the load power supply requirement, controlling a circuit between the whole vehicle power inlet port and the power supply port to be in a disconnected state and a circuit between the whole vehicle power inlet port and the grounding port to be in a disconnected state according to the power-saving control circuit. The invention is used for controlling the load power supply of the vehicle.

    本发明提供了一种一种车身控制器供电控制方法、装置及节电控制电路,涉及车辆供电领域,能够解决在车辆进行休眠模式和行驶模式的转换时,如何通过具体电路来使得车身控制器对供电进行有效的节能控制的问题,包括:确定车身控制器是否存在负载供电需求;在确定车身控制器存在负载供电需求的情况下,根据节电控制电路来控制整车进电端口与供电端口之间的电路为导通状态,且整车进电端口与接地端口之间的电路为导通状态;在确定车身控制器没有负载供电需求的情况下,根据节电控制电路来控制整车进电端口与供电端口之间的电路为断开状态,且整车进电端口与接地端口之间的电路为断开状态。本发明用于对车辆的负载供电进行控制。
