ABSTRACT:
A method of and an apparatus for controlling the moving speed of a vehicle, which makes a vehicle run at a constant speed independent of applied load by specifically instructing the moving speed according to the difference between the computed number of pulses and the actually detected number of pulses. The vehicle moving speed is properly controllable in correspondence with load applied to the moving vehicle. The apparatus includes a pulse generator which outputs pulses relative to the movement of the vehicle, a unit pulse calculation unit which counts the number of pulses outputted while the vehicle fully passes through a predetermined travel distance and then computes either the traveling distance per unit-pulses or the number of pulses per unit distance, a predetermined position operation unit which computes the number of pulses to be outputted in a specific period of time in which the vehicle from an optional position arrives at the predetermined position after elapse of the predetermined period of time on the basis of the computed number of outputted pulses and the setup speed at the moment of computing the number of pulses, and a present position computing unit which detects the number of pulses actually outputted in a predetermined period in which the vehicle from an optional position arrives at the predetermined position after elapse of a predetermined period of time, respectively.
