Abstract

A vehicle includes a high voltage component such as an electric actuator, an electric suspension control ECU, a battery, a signal line which transmits, to the electric suspension control ECU, a detection signal of a sensor disposed in the electric actuator, a high voltage line which supplies a high voltage from the battery to the electric actuator, and a fixing member which fixes the signal line and the high voltage line to a vehicle body, a length of the signal line from the fixing member to the electric actuator is shorter than a length of the high voltage line from the fixing member to the electric actuator, and the electric suspension control ECU suppresses the supply of the high voltage to the electric actuator, in a case where abnormality occurs in the signal line.

First claim

What is claimed is:

1. A vehicle comprising:
a high voltage component,
a control device,
a power source device,
a signal line which transmits, to the control device, a detection signal of a sensor disposed in the high voltage component,
a high voltage line which supplies a high voltage from the power source device to the high voltage component, and
a fixing member which fixes the signal line and the high voltage line to a vehicle body, wherein a length of the signal line from the fixing member to the high voltage component is shorter than a length of the high voltage line from the fixing member to the high voltage component, and
the control device suppresses the supply of the high voltage to the high voltage component, in a case where abnormality occurs in the signal line.

2. The vehicle according to claim 1 , further comprising:
a low voltage line which supplies a low voltage from the power source device to the high voltage component, wherein the fixing member fixes the low voltage line to the vehicle body,
a length of the low voltage line from the fixing member to the high voltage component is shorter than a length of the high voltage line from the fixing member to the high voltage component, and
the control device suppresses the supply of the high voltage to the high voltage component, in a case where abnormality occurs in the low voltage line.

3. The vehicle according to claim 1 , wherein the high voltage component includes an electric actuator driven with a motor in an electric suspension apparatus.

4. The vehicle according to claim 3 , wherein the sensor includes at least one of a rotation angle sensor which detects a rotation angle of the motor, a stroke sensor which detects a stroke of the electric actuator, and an acceleration sensor which detects an acceleration applied to the electric actuator.

5. The vehicle according to claim 1 , wherein the signal line is disposed in a forward direction of the vehicle body compared with the high voltage line.

6. The vehicle according to claim 1 , wherein the high voltage line is disposed inside the vehicle body compared with the signal line.
