    摘要： 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.

    摘要： A vehicle control system includes a sensor that generates a vehicle speed signal. A cruise control system generates a cruise control signal to maintain a vehicle at a target speed. A control module compares the vehicle speed signal to the target speed signal. The control module calculates different cruise control gains to delay changes in throttle position of the cruise control system when the vehicle speed signal is greater than the target speed.

    摘要： A control system for evaluating a brake booster system includes an engine evaluation module that detects an engine off condition. A pressure evaluation module, during the engine off condition, monitors hydraulic brake line pressure, detects a change in brake booster pressure, and determines a brake booster vacuum decay rate based on the change in brake booster pressure. A fault reporting module detects a brake booster system fault based on the brake line pressure and the brake booster vacuum decay rate.
