Abstract
An improved method for controlling the rate of deceleration and a point of stopping of a vehicle. Upon passing a first position marker, a first deceleration pattern is produced in an arithmetic circuit for stopping the train at a first predetermined point. Second and third deceleration patterns are produced when the vehicle passes a second position marker. In situations where the first deceleration pattern is a proper one, the vehicle velocity is subsequently conformed to the second deceleration pattern which controls the velocity of the vehicle at a lower deceleration rate than the first deceleration pattern, and stops the vehicle at a predetermined target point. However, in situations where an erroneous first deceleration pattern is produced such that the vehicle velocity is maintained at a higher level than either the first or second deceleration patterns, the velocity of the vehicle is subsequently conformed to the third deceleration pattern which is characterized by a high deceleration rate and will stop the vehicle at the target point.
