The invention relates to electrical distribution system monitoring for electric and autonomous vehicles. The disclosed systems and methods monitor power distribution systems for autonomous and drive-by-wire vehicles. The system can monitor input voltage, current, and other power signals, and reporting the input voltages and currents to a diagnostic engine control unit (ECU). The ECU compares the power signals with real-time (or substantially real-time) waveforms associated with vibrations, acceleration, road bumps, and other phenomena normally encountered in on-road operation, and evaluates any determined correlation between inertial events (e.g., bumps or acceleration, etc.) and changes in the power signals. If the diagnostic ECU determines a correlation between the inertial waveform, the diagnostic ECU map perform mitigating steps, such as issuing a vehicle health warning, generate instructions that cause the vehicle to navigate to a service center, or perform other mitigating actions.

    本公开提供了“用于电动车辆和自主车辆的配电系统监测”。所公开的系统和方法监测自主车辆和线控驱动车辆的配电系统。所述系统可监测输入电压、电流和其他功率信号,并且可将所述输入电压和电流报告给诊断发动机控制单元(ECU)。所述ECU将所述功率信号与和振动、加速度、道路颠簸和在道路上操作中通常遇到的其他现象相关联的实时(或基本上实时)波形进行比较,并且评估惯性事件(例如,颠簸或加速度等)与所述功率信号的变化之间的任何确定的相关性。如果所述诊断ECU确定了所述惯性波形之间的相关性,则所述诊断ECU可执行缓解步骤(诸如发出车辆健康警告)、生成使所述车辆导航到维修中心的指令或执行其他缓解动作。
