JPS6412316A - Vehicle traveling controller - Google Patents

Abstract

PURPOSE:To heighten an operation rate, by setting a difference between the detected value of a travel distance detecting means and a true travel distance in a vehicle as a correction quantity, and controlling the travel and the stoppage of the vehicle by comparing the difference between the correction quantities at a preceding time and this time with a prescribed value. CONSTITUTION:The rotation of the vehicle 9 of the vehicle 1 is detected by a pulse transmitter 10, and it is outputted to a position estimation circuit 5, and signals from reference position transmitters 16... arranged at a prescribed interval on a track T are outputted to a correction quantity detection circuit 21 via a reference position detection circuit 17, then, the correction quantity is found from data in a memory 6 where the data of the circuit 5 is stored, correction data due to signal transmission, etc., from a memory 20, and a reference position from the circuit 17, at the circuit 21. And when the vehicle 1 arrives at the next transmitter 16 and the circuit 21 receives the signal, the correction quantity at the preceding time is shifted to a memory 41, and also, the correction quantity is stored in a memory 4, and the absolute value of the difference between both correction quantities is compared with the prescribed value at an evaluation circuit 22, and an instruction is issued to a vehicle control circuit 15.
