Abstract: A method is disclosed for analyzing range and range rate data obtained by a vehicle obstacle detection system to determine whether the dynamic situation justifies alerting the vehicle operator of reducing the speed of the vehicle. Assumed values of vehicle and obstacle deceleration are used with known and assumed values of their velocities to calculate limiting warning distances that in turn are used to calculate an estimated warning distance. The estimated distance is compared with the range value as a basis of determining whether an alert is made.

Abstract: An improved occupant position detection system and method in which a periodically updated position output of an occupant recognition system (ORS) is dynamically augmented for purposes of determining if the occupant is out-of-position (OOP) so as to inhibit or allow deployment of occupant restraints in a timely manner. Vehicle acceleration data developed by an accelerometer of the restraint system is double integrated to form an incremental occupant displacement value. The incremental displacement value is reset to zero each time the ORS updates its position output, and between updates is used to modify the last position output to provide a dynamic position value for OOP determination. If the occupant is not wearing a seat belt, the incremental displacement value is combined with the last ORS position output both prior to and during the crash event.

Abstract: A method for monitoring motor position in a multiple phase switched reluctance motor having phase windings which are energized by a controller involves producing a signal indicative of a current delivered to an active phase winding and producing a signal indicative of a voltage across the active phase winding. A flux linkage associated with the active phase winding is then established based at least in part upon the current indicative signal and the voltage indicative signal. A position of the motor is then estimated based at least in part upon the current indicative signal and the established flux linkage.
