Abstract

A vehicle includes an electric actuator disposed outside a vehicle body, a battery 16 and a boosting circuit which supply a high voltage to the electric actuator, and an electric suspension control ECU which controls the boosting circuit and the electric actuator, and in a case where a running speed is equal to or less than a first speed, the electric suspension control ECU limits the supply of the high voltage to the electric actuator.

First claim

What is claimed is:

1. A vehicle comprising:
a high voltage component disposed outside a vehicle body,
a power source device which has a battery and a boosting circuit and which supplies a high voltage from the battery to the high voltage component, and
a processor which controls the power source device and the high voltage component, wherein
the processor, in a case where a running speed of the vehicle is equal to or less than a predetermined first speed, limits the supply of the high voltage to the high voltage component, and then determines whether or not the vehicle is in a stopped state, and in a case the processor determines that the vehicle is not in the stopped state and the running speed is equal to or more than a predetermined second speed that is a speed equal to or more than the predetermined first speed, releases limitation of supply of the high voltage to the high voltage component.

2. The vehicle according to claim 1 , wherein in a case where the running speed is equal to or less than the predetermined first speed, the processor limits a voltage supplied to the high voltage component to a predetermined voltage or less.

3. The vehicle according to claim 1 , wherein in a case where the vehicle is moving back, the processor limits a voltage supplied to the high voltage component to a predetermined voltage or less.

4. The vehicle according to claim 1 , wherein the high voltage component comprises a motor, and in a case where the vehicle is in the stopped state, the processor short-circuits the motor.

5. The vehicle according to claim 4 , wherein the high voltage component is an electric actuator of an electric suspension apparatus, and
the processor releases limitation of supply of the high voltage to the electric actuator, in a case where the vehicle starts running from the stopped state.

6. The vehicle according to claim 5 , wherein the processor determines whether the vehicle starts running, based on at least one of a depression position of a brake pedal and a depression position of an accelerator pedal.

7. The vehicle according to claim 4 , wherein
the processor, in the case where the running speed of the vehicle is equal to or less than the predetermined first speed and the vehicle is not in the stopped state, limits the supply of the high voltage to the motor without short-circuiting the motor, and then determines whether or not the vehicle is in the stopped state, and in the case the processor determines that the vehicle is not in the stopped state and the running speed is equal to or more than the predetermined second speed, releases limitation of supply of the high voltage to the motor.

8. The vehicle according to claim 1 , wherein
the predetermined first speed is 5 km/hr and the predetermined second speed is 10 km/hr.

9. The vehicle according to claim 1 , wherein
the processor, in the case where the running speed of the vehicle is equal to or less than the predetermined first speed and the vehicle is not in the stopped state, limits the supply of the high voltage to the high voltage component without short-circuiting the high voltage component, and then determines whether or not the vehicle is in the stopped state, and in the case the processor determines that the vehicle is not in the stopped state and the running speed is equal to or more than the predetermined second speed, releases limitation of supply of the high voltage to the high voltage component.
