摘要： A system and method for providing component and sub-system state of health prognosis in a complex system using fault models and component aging models. The method includes determining a current state of health value for a sub-system using fault signature test results and determining current state of health values for a plurality of components in the sub-system using the fault signature test results. The method also determines current state of health values for components in the system that cannot use fault signature test results using a first probability model and the current state of health values for the plurality of components. The method determines predicted future state of health values for the components in the sub-system using component aging models and determines a predicted future state of health value for the sub-system using a second probability model and the future state of health values of the components.

摘要： A disc braking system of a vehicle determines the actual temperature of a brake rotor. The disc braking system compares the actual temperature of the brake rotor to a critical temperature of the brake rotor. The critical temperature of the brake rotor is a temperature above which damage and/or warping to the brake rotor may occur. The disc braking system applies a corrective measure to prevent damage to the brake rotor when the actual temperature of the brake rotor is greater than the critical temperature of the brake rotor. The corrective measure may include, but is not limited to: displaying a warning, adjusting a fraction control system of the vehicle, scheduling maintenance for the vehicle.

摘要： A system and method for determining whether a particular wheel on a vehicle is un-balanced during operation of the vehicle. The method includes providing wheel angle signals from the wheels of the vehicle and providing a vibration measurement signal from a response point on the vehicle, such as from an accelerometer on a steering column of the vehicle. The method also includes generating a regression vector using the wheel angle signals. The method also includes generating an estimated parameter vector using a recursive least squares algorithm, the regression vector and the vibration measurement signal. The method then calculates an imbalanced magnitude value of each wheel of the vehicle using the estimated parameter vector. The method uses a persistency of excitation test to determine whether the parameter vector has converged to a true value to determine whether the calculated imbalanced magnitude values are accurate.

摘要： A pedestrian warning system includes a sensing device that is provided on the vehicle for detecting a pedestrian within a predetermined zone around the vehicle. A warning device on the vehicle generates a warning signal perceived by the pedestrian outside the vehicle indicating a presence of the vehicle. A speed sensor senses a speed of the vehicle. A controller is configured to receive a signal from the sensing device indicating the detection of the pedestrian within the predetermined zone. The controller determines whether the speed of the vehicle is within a predetermine speed range. The controller actuates the warning device for warning the pedestrian of the close proximity to the vehicle in response to determining the vehicle traveling at a respective speed is within the predetermined speed range and detecting the presence of the pedestrian within the predetermined zone.
