Vehicle speed control system
Abstract
Abstract AN AUTOMATIC CONTROL SYSTEM FOR A MOTOR VEHICLE HAVING ADJUSTABLE SPEED CONTROL APPARATUS COMPRISES ONE OR MORE RADIO FREQUENCY TRANSMITTERS, THE OUTPUTS OF WHICH ARE MODULATED BY COMMAND SIGNALS OF PREDETERMINED DIFFERENT FREQUENCIES INDIVIDUALLY IDENTIFIED WITH AN ASSIGNED SPEED LIMIT. A RECEIVER CARRIED BY THE VEHICLE INCLUDES A DEMODULATOR FOR DETECTING THE COMMAND SIGNALS, A SIGNAL TRANSLATING CIRCUIT FOR DEVELOPING A CONTROL SIGNAL AND AN ELECTROMECHANICAL DEVICE WHICH ENGAGES THE SPEED CONTROL APPARATUS UPON RECEIPT OF A COMMAND SIGNAL TO RESTRICT THE SPEED OF THE VEHICLE TO THE SPEED LIMIT ASSIGNED TO THE COMMAND SIGNAL. THE OUTPUT OF THE SIGNAL-TRANSLATING CIRCUIT IS COUPLED TO THE ELECTROMECHANICAL DEVICE BY MEANS RESPON- SIVE TO THE SPEED OF THE VEHICLE AND, FOR EMERGENCY PURPOSES, OPERATOR CONTROLLABLE MEANS ARE PROVIDED TO PERMIT DISENGAGING THE ELECTROMECHANICAL DEVICE FROM THE SPEED CONTROL APPARATUS FOR A PREDETERMINABLE PERIOD.
