The system comprises a remote control unit and a vehicle operation unit. The remote control unit has a keyboard for selecting a personal code and also for selecting one or more function codes which are designed to be executed by the vehicle operation unit. An encoding circuit generates a code which corresponds to the personal code and a function code. A transmitter is provided with the remote control unit for transmitting signal codes. The vehicle operation unit has a receiver and a decoder for receiving an verifying the personal code and the function code. A processing unit is provided with the vehicle operation unit to process the codes and to operate interface circuits which operate functions of the vehicle corresponding to the function code. A coding and transmitting circuit is also provided with the vehicle operation unit for transmitting to the control unit a confirmation signal to confirm that the selected function by the control unit have been executed and is operational.Field of SearchWITH MEANS FOR CONTROLLING OPERATION RESPONSIVE TO ELECTROMAGNETIC RADIATION, MAGNETIC FORCE, OR SOUND WAVES RECEIVED FROM SOURCE, OR REFLECTED FROM OBJECT OR SURFACE, LOCATED APART FROM VEHICLEElectric-starting motor Miscellaneous collection of automatic engine starters Acknowledgement Answer-back Interrogator-responder Transmitter for remote control signal | |
