## CPC

- B60K 6/40: characterised by the assembly or relative disposition of components
- B60K: ARRANGEMENT OR MOUNTING OF PROPULSION UNITS OR OF TRANSMISSIONS IN VEHICLES; ARRANGEMENT OR MOUNTING OF PLURAL DIVERSE PRIME-MOVERS IN VEHICLES; AUXILIARY DRIVES FOR VEHICLES; INSTRUMENTATION OR DASHBOARDS FOR VEHICLES; ARRANGEMENTS IN CONNECTION WITH COOLING, AIR INTAKE, GAS EXHAUST OR FUEL SUPPLY OF PROPULSION UNITS IN VEHICLES

## Abstract

A cable routing structure includes a drive train within which an electric motor is housed; a power control unit configured to supply alternating current to the electric motor, the power control unit being fixed to an upper portion of the drive train, and on-board components being arranged on both sides of the power control unit in a lateral direction of a vehicle; an electrical component being arranged on a side of a plane that the power control unit is on; and a first end of a first cable being connected to a side surface of the power control unit that faces toward a front or a rear of the vehicle, a second end of the first cable being connected to the electrical component, and the first cable being routed through a space defined by the power control unit and the drive train.

## Claims

### Claim 1

A cable routing structure comprising:
a drive train;
an electric motor housed within the drive train;
a power control unit configured to convert electric power of a battery to alternating current and supply the alternating current to the electric motor, the power control unit being fixed to an upper portion of the drive train, and on-board components being arranged on both sides of the power control unit in a lateral direction of a vehicle;
an electrical component arranged on a side of a plane on which the power control unit is present, the plane including a side surface of the power control unit that faces toward a front or a rear of the vehicle; and
a first cable connecting the power control unit to the electrical component, a first end of the first cable being connected to the side surface of the power control unit, a second end of the first cable being connected to the electrical component, and the first cable being routed through a space defined by the power control unit and the drive train.

### Claim 2 (depends on 1)

The cable routing structure according to claim 1, wherein the power control unit is fixed to the upper portion of the drive train via a bracket.

### Claim 3 (depends on 2)

The cable routing structure according to claim 2, further comprising:
a battery supplying electric power to the electrical component via a circuit inside the power control unit, the battery being arranged in a position facing the side surface of the power control unit to which the first end of the first cable is connected; and
a second cable connected to the battery and the power control unit, a third end of the second cable being positioned on the power control unit side of the second cable, and the third end of the second cable being connected to the side surface of the power control unit to which the first end of the first cable is connected.

### Claim 4

A cable routing structure comprising:
a drive train;
an electric motor housed within the drive train;
a power control unit configured to convert electric power of a battery to alternating current and supply the alternating current to the electric motor, the power control unit being fixed to an upper portion of the drive train, and on-board components being arranged on both sides of the power control unit in a lateral direction of a vehicle;
an electrical component arranged farther forward than the power control unit in a longitudinal direction of the vehicle; and
a first cable connecting the power control unit to the electrical component, a first end of the first cable being connected to a rear surface of the power control unit that faces toward a rear of the vehicle, a second end of the first cable being connected to the electrical component, and the first cable being routed through a space defined by the power control unit and the drive train.

### Claim 5 (depends on 4)

The cable routing structure according to claim 4, wherein the power control unit is fixed to the upper portion of the drive train via a bracket.

### Claim 6 (depends on 5)

The cable routing structure according to claim 5, further comprising:
a battery supplying electric power to the electrical component via a circuit inside the power control unit, the battery being arranged in a position facing the rear surface of the power control unit; and
a second cable connected to the battery and the power control unit, a third end of the second cable being positioned on the power control unit side of the second cable, and the third end of the second cable being connected to the rear surface of the power control unit.
