Abstract

A vehicle includes an acceleration sensor detecting collision, an electric actuator disposed outside a vehicle body, a battery and a boosting circuit supplying a high voltage to the electric actuator, and an electric suspension control ECU controlling the boosting circuit and the electric actuator, and in a case where the acceleration sensor detects the collision, 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 collision sensor detecting collision of the vehicle;
an electrical suspension apparatus that is coupled to a wheel of the vehicle through a coupling part;
a battery that supplies power to an electrical actuator of the electrical suspension apparatus; and
a processor which controls the electrical suspension apparatus and the battery,
wherein
the collision sensor is an acceleration sensor that is disposed on the electrical actuator and that detects an acceleration applied to the coupling part from the wheel side, and
the processor, in a case where the acceleration detected by the acceleration sensor is equal to or greater than a predetermined value, detects the collision, and reduces a voltage of the power supplied to the electrical actuator.

2. The vehicle according to claim 1 , wherein
in the case where the collision is detected, the processor short-circuits the electrical actuator.

3. The vehicle according to claim 2 , wherein the processor maintains the short circuit of the electrical actuator from when the collision is detected until the vehicle stops.

4. The vehicle according to claim 1 , wherein
the processor controls the electric actuator based on a detection result of the acceleration sensor.

5. The vehicle according to claim 1 , wherein
the acceleration sensor is disposed to tilt by a predetermined angle in a front-rear direction or width direction of a vehicle body of the vehicle to the vertical direction, and
the processor detects the collision of the vehicle based on a component of the acceleration detected by the acceleration sensor in a tilted direction of the acceleration sensor.
