The invention relates to a diagnostic system, a vehicle, a diagnostic method, and a computer readable storage medium. A diagnostic system diagnoses a rotating part of a rotating electric machine provided in a vehicle while the vehicle is traveling. The diagnostic system is provided with: a measurement unit that, when diagnosing the rotating unit, stops charging from the rotating electric machine to a battery provided in the vehicle, and measures the induced voltage of the rotating electric machine generated by the rotation of the rotating unit; and a determination unit that determines that the rotating unit is abnormal when the magnitude of the induced voltage is equal to or greater than a predetermined value. The method includes: a step of stopping charging from the rotating electric machine to a battery provided in the vehicle and measuring an induced voltage of the rotating electric machine generated by rotation of the rotating part when diagnosis of the rotating part is performed; and a step of determining that the rotating part is abnormal when the magnitude of the induced voltage is equal to or greater than a predetermined value.

    本发明涉及诊断系统、车辆、诊断方法和计算机可读存储介质。诊断系统在车辆的行驶中进行所述车辆所具备的旋转电机的旋转部的诊断。诊断系统具备计测部,该计测部在进行旋转部的诊断的情况下,使从旋转电机向车辆所具备的蓄电池的充电停止,并计测由旋转部的旋转产生的旋转电机的感应电压;以及在感应电压的大小为预定值以上的情况下,判断为旋转部异常的判断部。方法具有:在进行旋转部的诊断的情况下,使从所述旋转电机向所述车辆所具备的蓄电池的充电停止,并计测由旋转部的旋转产生的旋转电机的感应电压的步骤;以及在感应电压的大小为预定值以上的情况下,判断为旋转部异常的步骤。
