Abstract
A vehicle guiding system enables a plurality of vehicles to run in a platoon with minimum assistance from drivers, and is intended to enhance effective use of from auto-drive lane. When the vehicle runs in the platoon, a front running vehicle detects its displacement from a magnetic nail, and calculates a steering amount to be corrected (i.e. control variables). The front running vehicle not only controls its own movements on the basis of the control variable data but also transmits them to a following vehicle. The following vehicle does not detect its displacement from the magnetic nail, but controls its steering amount on the basis of the received control variable data. The first following vehicle transfers the control variable data to a further following vehicle. The further following vehicle simply receives the control variable data from the following vehicle, and does not calculate its own control variables. This reduces a distance between the vehicles which is necessary for each vehicle to perform such calculation.
