Abstract

A vehicle includes a collision determination ECU determining whether a possibility of collision is present, based on a detection result of a detection sensor detecting outside of the vehicle, a motor, a boosting circuit and a battery supplying a high voltage to the motor, and an electric suspension control ECU controlling the boosting circuit and the motor, and in a case where the collision determination ECU determines that the possibility of collision is present, the electric suspension control ECU limits the supply of the high voltage to the motor.

First claim

What is claimed is:

1. A vehicle comprising:
a collision determination device having a first processor that determines whether a possibility of collision between the vehicle and an obstacle is present, based on a detection result of a detection sensor detecting the obstacle outside of the vehicle;
a high voltage component which is a motor for driving an electric actuator in an electric suspension apparatus;
a power source device for supplying a high voltage to the high voltage component, the high voltage being used for driving the high voltage component; and
a control device having a second processor that controls the power source device and the high voltage component, wherein
the power source device includes a battery and a boosting circuit that boosts a voltage supplied from the battery to the high voltage component, and
in a case where the first processor of the collision determination device determines that the possibility of collision is present, the second processor of the control device limits the supply of the high voltage to the high voltage component by controlling the boosting circuit to set the voltage to be supplied to the high voltage component to a predetermined voltage or lower.

2. The vehicle according to claim 1 , wherein
the second processor of the control device short-circuits the motor, after supply of the high voltage to the motor is limited.

3. The vehicle according to claim 1 , wherein the second processor of the control device releases limitation of the supply of the high voltage to the high voltage component, in a case where the supply of the high voltage to the high voltage component is limited, and then a predetermined condition is satisfied.

4. The vehicle according to claim 3 , wherein the predetermined condition includes at least one of a condition that the vehicle runs at a predetermined vehicle speed or more for a predetermined time and a condition that the vehicle runs a predetermined distance.

5. The vehicle according to claim 1 , wherein the high voltage is 33V to 37V.

6. The vehicle according to claim 1 , wherein the voltage supplied from the battery is 12V to 16V.

7. The vehicle according to claim 1 , wherein the predetermined voltage is 20V to 30V.
