  • Relay control between power distribution center and body control module
    Patent number: 9517737
    Abstract: Electrical devices in a vehicle engine compartment are controlled from the vehicle passenger compartment over a serial data bus that extends between a relay controller located in the engine compartment and a body control module located in the passenger compartment and which receives commands from various passenger compartment devices. A serial data link passing through the firewall couples the body control module to the relay controller.

  • OVERCURRENT DETECTION LATCH CIRCUIT
    Publication number: 20080225455
    Abstract: An overcurrent detection circuit assembly provides a diagnostic feedback signal indicative of an overcurrent or short condition is disclosed. The detection circuit receives a sense current that is proportional to a load current provided to an electrical device or load. The detection circuit provides the feedback signal to a microcontroller that can control the device and the power supply to protect the device against short circuit or other fault condition.

  • Vehicle light system circuit which automatically compensates for a light source failure
    Patent number: 6281631
    Abstract: A vehicle light system circuit includes a PROFET to automatically detect the presence of a faulty light source and switch to an unaffected light source. The system also adjusts the brightness of the unaffected light source by adjusting a PWM signal applied thereto to approximate the brightness of the unaffected light source.
