PURPOSE:To obtain a position detector for vehicle which controls the position of a vehicle with a high precision and has no restrictions on setting of a route and easily changes the route. CONSTITUTION:This device consists of a marker discharging means 10 which discharges markers 20 from the front end of the vehicle onto the road surface at intervals of a preliminarily determined time in the going direction of the vehicle, a marker position detecting means 30 which detects the positions of these discharged markers 20, a control means 40 which calculates the position of the vehicle by marker position data from the marker position detecting means 30 and controls the going direction of the vehicle based on the calculation result, and a marker recovering means 50 which recovers markers 20 whose positions are already detected to the rear part of the vehicle. |
