Abstract

Installation cart for laying a magnetic marker in a road to achieve driving assist control on a vehicle side has boring drill at each of front and rear of vehicle body, the boring drill boring accommodation hole as a laying position for the magnetic marker in road surface, is capable of boring accommodation holes at two locations with a predetermined space without moving in a state of being parked at any position, and is capable of performing efficient laying operation without requiring, for example, positioning of installation cart for enhancing accuracy of a space between these accommodation holes at two locations forming the laying positions.

First claim

The invention claimed is:

1. An installation device for laying a magnetic marker in a road, comprising:
an operation unit which provides a laying position for the magnetic marker, wherein
the installation device is capable of providing the laying position for the magnetic marker at each of a plurality of locations without moving, the plurality of locations having a predetermined relative position relation, and
further comprising an azimuth information acquisition unit which acquires azimuth information for identifying an orientation of an arrangement shape of the plurality of the laying positions for the plurality of the magnetic markers at the plurality of locations.

2. The installation device in claim 1 , wherein the installation device comprises a plurality of the operation units and, in the installation device, each of a plurality of the operation units is arranged for each of a plurality of the laying positions for a plurality of the magnetic markers at the plurality of locations.

3. The installation device in claim 1 , wherein the installation device is provided with a position-measurement location where a relative position relation with the operation unit is identified, and comprises a position information acquisition unit for acquiring position information of the position-measurement location.

4. The installation device in claim 2 , wherein the installation device is provided with a position-measurement location where a relative position relation with the operation unit is identified, and comprises a position information acquisition unit for acquiring position information of the position-measurement location.
