The invention relates to the technical field of motor vehicles, particularly provides a control method of a load control circuit, the load control circuit and a motor vehicle, and aims to solve the problem that no power supply is provided for a circuit at the rear end of a fuse after the fuse is fused or breaks down. In order to achieve the purpose, the invention discloses the control method of the load control circuit, and the load control circuit comprises an overload protection unit and a load element electrically connected with the output end of the overload protection unit; the control method comprises the following steps: acquiring a first temperature Temp1 of the overload protection unit, and acquiring a preset temperature Temp0 of the overload protection unit; comparing the relationship between the Temp1 and the Temp0; and selectively adjusting the working state of the load element according to the comparison result. According to the control method of the load control circuit, the temperature condition of the overload protection unit can be obtained by detecting the first temperature Temp1 of the overload protection unit, the working state of the load element is controlled according to the temperature condition of the overload protection unit, and the reliability of system power supply is guaranteed.

    本发明涉及机动车技术领域,具体提供一种负载控制电路的控制方法、负载控制电路以及机动车,旨在解决保险丝熔断或发生故障后,保险丝后端电路没有电源供给的问题。为此目的,本发明的公开了一种负载控制电路的控制方法,负载控制电路包括:过载保护单元以及与过载保护单元的输出端电连接的负载元件;控制方法包括以下步骤:获取过载保护单元的第一温度Temp1、获取过载保护单元的预设温度Temp0;比较Temp1与Temp0的关系;根据比较结果,选择性地调节负载元件的工作状态。本发明的负载控制电路的控制方法,通过检测过载保护单元的第一温度Temp1,可获得过载保护单元的温度情况,并根据过载保护单元的温度情况,控制负载元件的工作状态,保证系统供电的可靠性。
