  • Remote starting system for a vehicle having a diesel engine
    Patent number: 5617819
    Abstract: A system for remotely starting a diesel engine of a vehicle. The system comprises a portable hand-held RF transmitter issuing a command in the form of a binary-coded sequence. A slave controller mounted on-board the vehicle executes the command by energizing the starter motor in order to crank and start-up the diesel engine. The system includes a Hall-effect sensor responsive to the pulsating magnetic field of the diesel engine alternator for generating a signal indicative of the rotational speed of the engine. The slave controller uses this information for detecting when the engine has been successfully started in order to de-energize the starter motor.
