A vehicle control unit is disclosed which can be coupled between a tachometer sensor and an electronic ignition system on a vehicle. The unit is also coupled to a speedometer sensor to measure the vehicle's speed. The vehicle control unit limits the vehicle speed by monitoring the tachometer signal from the tachometer sensor and passing the tachometer signal to the ignition system if the engine speed is within predetermined limits. The tachometer signal is a pulse train which is used by the electronic ignition system to determine ignition timing. The vehicle control unit limits both vehicle speed and engine speed by disconnecting pulses from the tachometer sensor and generating time-delayed pulses of its own to delay the combustion of fuel until after the instance of maximum fuel compression, thereby reducing engine power when the vehicle or engine speeds exceed predetermined limits.

Engine limiter for powered vehicles

A current controller for controlling an input current carried by a primary conductor. The current controller has a gapped core of magnetic material magnetically coupled to the primary conductor, as for example by the primary conductor being wound around the core. A secondary conductor is magnetically coupled to the core of magnetic material in an opposite manner to the primary conductor such that current flowing in the secondary conductor generates a second magnetic field in the core opposed to the first magnetic field. A Hall effect latch is located in the air gap and has output voltage corresponding to a hysteresis function of the difference in the first and second magnetic fields.
