Abstract: An intelligent system and method detects and prevents vehicle rollover conditions. An accelerator determines vehicle speed and lateral G force, a processor computes the center of mass of the vehicle by correlating the lateral G force produced while the vehicle is turning, and an alert that is activated if the speed is exceeded or if the turn radius is reduced beyond safety limits indicative of potential rollover of the vehicle. The preferred embodiment further includes a gyroscope operative to sense lateral yaw rate excursions of the vehicle, enabling the processor to correlate the yaw rate excursions at a given speed with the lateral G forces produced while the vehicle is turning. The accelerator may further be operative to determine vertical acceleration at a given speed along a third axis, and augment rollover alarm conditions on rough road surfaces. The processor may additionally be operative to compute the absolute maximum lateral angle of vehicle stability for a given center of mass, and trigger the alert if this value is approached during vehicle operation or when vehicle speed is zero.

Abstract: A diagnostic system for a brake booster sensor includes a monitor that monitors a maximum error and a minimum error based on a brake booster sensor signal over a monitoring period. A first comparator determines one of a pass status and a fail status of the brake booster sensor based on the maximum error and the minimum error.

Abstract: A method for detecting a missing or improperly installed fuel cap on a vehicle includes a first leak test that detects a leak in an evaporative emissions system of a vehicle. A refueling test detects a refueling of the vehicle when the first leak test detects the leak. A fuel cap indicator in the vehicle is activated when the first leak test detects the leak and the refueling test detects the refueling. The fuel cap indicator is deactivated after a predetermined time period. The fuel cap indicator remains deactivated when a predetermined number of leak tests consecutively detect the leak. The fuel cap indicator is deactivated when an occupant of the vehicle indicates that a fuel cap of the vehicle is properly installed. The occupant activates an actuator on an instrument panel of the vehicle to indicate the fuel cap is properly installed.

Abstract: A leak detection system for a vehicle includes a fuel system and a controller. The controller communicates with the fuel system to detect a fuel filling event. The controller initiates a vapor leak test of the fuel system and terminates the vapor leak test if a fuel filling event is detected.

Abstract: An intelligent system and method detects and informs operators of unstable vehicle conditions. An accelerometer and gyro based micro-controller system dynamically computing the center of mass, speeds, positions, angles, stability factors, Velocity-Road Roughness Index, Dynamic Stability Function, and other parameters critical in determining the dynamics of vehicle motion. The apparatus may be integrated into an overall vehicle network and may incorporate a method for detecting and warning vehicle operators of unstable driving conditions which may include rollover, high velocity turns, sideslope conditions, rough roads, slip, and other dynamic events.
