Abstract: A control device for an electric vehicle including a traveling motor which is configured to transmit a driving force to driving wheels, includes: a control unit having a suppression mode function for suppressing a traveling state amount of the vehicle when an abnormality occurs in an electrically driven system of the vehicle. The suppression mode function includes a first suppression state and a second suppression state, and a suppression degree in the second suppression state is smaller than a suppression degree in the first suppression state. In accordance with a kind of the abnormality in the electrically driven system, the control unit is configured to cause the vehicle to be in the first suppression state or is configured to cause the vehicle to be in the first suppression state after causing the vehicle to be in the second suppression state.

Abstract: A fault diagnostic device of a vehicle includes a starting circuit which causes a charger mounted on the vehicle to output a charging start signal and thereby activate a control unit for controlling charging of a battery mounted on the vehicle when a charging gun is connected to the charger. The control unit causes the charger to output the charging start signal when the charger is activated in response to turning on of an ignition switch, and has a fault determination function whereby, if the control unit is not input with the charging start signal, it is judged that a disconnection or power-supply short circuit has occurred in a charging start signal circuit of the starting circuit.
