## Abstract

Provided is a vehicle sensor mounting structure by which a GNSS antenna and at least one external sensor are mounted on a roof of a vehicle, the at least one external sensor being configured to detect an external state of the vehicle. The vehicle sensor mounting structure includes: a first wiring hole into which a sensor wiring line of the at least one external sensor is drawn to be placed under the roof, the first wiring hole being formed in the roof; and a second wiring hole into which an antenna wiring line of the GNSS antenna is drawn to be placed under the roof, the second wiring hole being formed in the roof.

## Claims

### Claim 1

A vehicle sensor mounting structure by which a GNSS antenna and at least one external sensor are mounted on a roof of a vehicle, the at least one external sensor being configured to detect an external state of the vehicle, the vehicle sensor mounting structure comprising:
a first wiring hole into which a sensor wiring line of the at least one external sensor is drawn to be placed under the roof, the first wiring hole being formed in the roof; and
a second wiring hole into which an antenna wiring line of the GNSS antenna is drawn to be placed under the roof, the second wiring hole being formed in the roof, wherein
the at least one external sensor is connected to a power supply under the roof via a sensor power supply wiring line;
the GNSS antenna is connected to the power supply via an antenna power supply wiring line;
the sensor power supply wiring line connects the at least one external sensor to the power supply by passing through the first wiring hole; and
the antenna power supply wiring line connects the GNSS antenna to the power supply by passing through the second wiring hole.

### Claim 2 (depends on 1)

The vehicle sensor mounting structure according to claim 1, wherein the first wiring hole and the second wiring hole are formed to be distanced from each other by a hole interference reduction distance or more.

### Claim 3 (depends on 1)

The vehicle sensor mounting structure according to claim 1, wherein the at least one external sensor and the GNSS antenna are placed to be distanced from each other by a sensor interference reduction distance or more.

### Claim 4 (depends on 1)

The vehicle sensor mounting structure according to claim 1, wherein the sensor wiring line and the antenna wiring line are placed to be distanced from each other by a wiring-line interference reduction distance or more.

### Claim 5 (depends on 1)

The vehicle sensor mounting structure according to claim 1, wherein the roof of the vehicle functions as a shield by being connected to ground via a conductive material.
