  • Fuel door sensor diagnostic systems and methods
    Patent number: 8000856
    Abstract: A diagnostic system for a vehicle comprises a refueling indicator module and a diagnostic module. The refueling indicator module selectively indicates when a refueling event occurs. The diagnostic module selectively diagnoses a fault in a fuel door position sensor when the fuel door position sensor indicates that a fuel door is in one of an open position for less than a first predetermined period when the refueling event occurs and a closed position for greater than a second predetermined period when the refueling event occurs.
    Type: Grant

  • Transmission load modeling for engine idle speed control
    Patent number: 6857987
    Abstract: An idle speed compensation system for a vehicle includes an idle speed control system that varies airflow to an engine at idle and a transmission driven by the engine. A controller communicates with the idle speed control system, the engine, and the transmission. The controller generates an idle speed compensation signal based on a transmission load.
