ABSTRACT:
An improved system for supplying electric power to and automatically controlling the speed of driverless electrically motivated wheeled vehicles on a guideway utilizing a plurality of guideway disposed power busses, each supplied by a sequentially variable frequency power supply. The vehicle is propelled by an electric motor sequentially in contact with the busses. The speed of the motor is controlled by the particular power frequency encountered at each buss while the vehicle moves forward on the guideway. One or more designated stop and start zones are selected for stop and start journey events in which the busses within the zone are alternatively powered by either a series of power supplies emitting frequencies at which the vehicle will decelerate to a stop or a series of power supplies emitting frequencies at which the vehicle will accelerate forward from a stopped position or alternatively continue in the normal course of travel. A switching device selects one or the other series of power supplies depending upon the desired course of action.
