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 in a case where a running speed is equal to or less than a predetermined speed, the processor limits the 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 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 stopped, 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 a state where the vehicle is stopped.

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.
