ABSTRACT:
Apparatus is provided for controlling the speed of a vehicle, especially vehicles of a railway train, wherein acceleration-imparting mechanisms associated with the wheels are adjusted on an individual basis by comparison of tangential speed and desired speed by the use of sensors to maintain the tangential speeds of the wheels equal to each other, and equal to a predetermined value. The technique may be employed in either the braking or the propulsion mode of operation, or in both modes, and allows commanded rates of vehicle acceleration to be realized to the greatest possible extent.
