一种功率电路包括电源和将电源连接到车辆子系统的多个部件。故障检测模块接收电源输出端处和子系统输入端处的电压以及子系统汲取的电流,并基于对电压和电流的分析来在电源故障、部件中的一者与电源的永久和间歇性断开、以及功率电路和子系统之间的松动连接或部件中的一者的腐蚀之间进行区分。故障缓解模块通过切换到车辆中的不同电源以向子系统供应功率来缓解前两个故障,并通过减少子系统消耗的功率以及通过生成关于间歇性断开或松动连接的警告来缓解第三和第四故障。

    A power circuit includes a power source and a plurality components that connect the power source to a subsystem of a vehicle. A fault detection module receives voltages at an output of the power source and at an input of the subsystem and current drawn by the subsystem, and distinguishes between a power source failure, a permanent and an intermittent disconnection of one of the components from the power source, and a loose connection between the power circuit and the subsystem or corrosion of one of the components, based on analyses of the voltages and the current. A fault mitigation module mitigates the first two faults by switching to a different power source in the vehicle to supply power to the subsystem, and mitigates the third and fourth faults by reducing the power consumed by the subsystem and by generating a warning regarding the intermittent disconnection or loose connection.
