1. A train-of-vehicle travel support device comprising:
- a sensor unit mounted on a vehicle and measuring a three-dimensional position and a shape of a feature on a road to produce a road line shape data;
a processor unit mounted on the vehicle and comparing the road line shape data to a reference data showing a three dimensional position and shape of the feature on the road surface which has been previously stored, computing a difference between the road line shape data and the reference data, and obtaining running control data of the vehicle based on the difference; and
an inter-vehicle communication device transmitting the running control data of the vehicle to a following vehicle which obtains running control data of the following vehicle based on the transmitted running control data of the vehicle.

Abstract
A train-of-vehicle travel support device which enables a train-of-vehicle travel of a plurality of vehicles even on a running road in which no magnetic marker is embedded. The train-of-vehicle travel support device includes a sensor unit obtaining road line shape data of a feature on a road surface, a processor unit obtaining running control data based on comparison of the road line shape data obtained by the sensor unit and reference data which has been previously stored, and an inter-vehicle communication device transmitting wirelessly the running control data obtained by the processor unit to a following vehicle.

5. A control system of a vehicle being mounted on the vehicle, the control system comprising:
-
a measurement unit for measuring a three-dimensional position and a shape of a feature on a road to produce a road line shape data; a memory unit for previously storing a reference data showing a three-dimensional position and a shape of a feature on a road; and a computing unit for computing a difference between the road line shape data and the reference data, and obtaining running control data of the vehicle based on the difference. - View Dependent Claims (6)

- 7. A processor unit mounted in a vehicle that follows a preceding vehicle and which obtains running control data of the vehicle based on running control data of the preceding vehicle received from a processor in the preceding vehicle that obtains the running control data of the preceding vehicle based on a difference between road line shape data indicating a three-dimensional position and a shape of a feature measured by the preceding vehicle and reference data showing a three-dimensional position and a shape of a feature which has been previously stored.
