Abstract

A vehicle includes a motor, an inverter, an inter-line short circuit, an operation circuit, and a harness. The motor is provided in a wheel. The inverter is configured to supply electric power to the motor. The inter-line short circuit is provided in the wheel and configured to cause the motor to be short-circuited when not in operation and couple the motor and the inverter when in operation. The operation circuit is provided in a vehicle body of the vehicle and configured to operate the inter-line short circuit. The harness extends between the wheel and the vehicle body. In the harness, at least one power supply line, which is configured to supply electric power to the motor through the inverter and the inter-line short circuit, and an operation line, which is configured to couple the inter-line short circuit and the operation circuit, are bundled.

First claim

The invention claimed is:

1. A vehicle comprising:
a motor provided in a wheel;
an inverter configured to supply electric power to the motor;
an inter-line short circuit provided in the wheel and configured to cause the motor to be short-circuited in a case where the inter-line short circuit is not operated and couple the motor and the inverter in a case where the inter-line short circuit is operated;
an operation circuit provided in a vehicle body of the vehicle and configured to operate the inter-line short circuit; and
at least one harness that extends between the wheel and the vehicle body and in which at least one power supply line and an operation line are bundled, the at least one power supply line being configured to supply electric power to the motor through the inverter and the inter-line short circuit, and the operation line being configured to couple the inter-line short circuit and the operation circuit.

2. The vehicle according to claim 1 , wherein the operation line is configured to break more easily than the at least one power supply line.

3. The vehicle according to claim 1 , wherein
the inverter is provided in the vehicle body,
the at least one power supply line comprises multiple power supply lines, and the at least one harness comprises multiple harnesses, and
the multiple power supply lines are individually bundled with the operation line in the respective harnesses.

4. The vehicle according to claim 2 , wherein
the inverter is provided in the vehicle body,
the at least one power supply line comprises multiple power supply lines, and the at least one harness comprises multiple harnesses, and
the multiple power supply lines are individually bundled with the operation line in the respective harnesses.

5. The vehicle according to claim 1 , wherein the inverter is provided in the wheel, and
wherein the at least one power supply line supplies electric power to the inverter.

6. The vehicle according to claim 2 , wherein the inverter is provided in the wheel, and
wherein the at least one power supply line supplies electric power to the inverter.

7. The vehicle according to claim 1 , wherein the inter-line short circuit is disposed in the motor.

8. The vehicle according to claim 2 , wherein the inter-line short circuit is disposed in the motor.

9. The vehicle according to claim 3 , wherein the inter-line short circuit is disposed in the motor.

10. The vehicle according to claim 4 , wherein the inter-line short circuit is disposed in the motor.

11. The vehicle according to claim 5 , wherein the inter-line short circuit is disposed in the motor.

12. The vehicle according to claim 6 , wherein the inter-line short circuit is disposed in the motor.
