摘要:
An apparatus is provided for controlling a vehicle actuatable occupant restraining system. A central crash accelerometer senses crash acceleration at a central vehicle location provides a first crash acceleration signal. A side-satellite accelerometer senses crash acceleration substantially parallel with a front-to-rear axis of the vehicle and provides a signal indicative thereof. A controller actuates the actuatable occupant restraining system in response to the central crash acceleration signal and the side-satellite signal.

An apparatus (10) for controlling actuation of at least one actuatable protection device (18, 20, 22, 24) includes a controller (26) having a first sensor input effective to receive a first sensor signal (64, 66, 70) having a value indicative of a first condition of an occupant of the vehicle seat (14, 16). The apparatus (10) also includes a second sensor input effective to receive a second sensor signal (82, 84, 86, 88, 94) having a value indicative of a second condition of the occupant of the vehicle seat (14, 16). The controller (26) is operative to determine a default value for the value of the first sensor signal (64, 66, 70) upon determining that the value of the first sensor signal is either outside an expected range of values or is absent. The controller (26) is operative to provide a control signal (136, 174, 176) to control actuation of at least one actuatable protection device (18, 20, 22, 24). The control signal (136, 174, 176) has a value that varies as a function of the value of the second sensor signal and at least one of the received first sensor signal and the determined default value of the first sensor signal.

A method for determining a crash condition of a vehicle comprises the step of sensing crash acceleration in a first direction substantially parallel to a front-to-rear axis of the vehicle and providing a first crash acceleration signal indicative thereof. The method also comprises the step of sensing crash acceleration in a second direction substantially parallel to a side-to-side axis of the vehicle and providing a second crash acceleration signal indicative thereof. The method further comprises the steps of determining a crash metric value functionally related to the sensed crash acceleration based on the second acceleration signal and comparing the determined crash metric value as a function of the sensed first crash acceleration signal against an associated threshold. The method still further comprises the step of determining a crash condition of the vehicle in response to (a) the comparison and (b) the first acceleration signal.

摘要:
An apparatus (50) detects a pedestrian/vehicle impact, the apparatus including a plurality of sensors (62, 64, 66) mounted near a forward location of a vehicle (52), each sensor providing an associated signal indicative of an impact event. A metric determining device (80) determines metric values for each of the sensor signals. A controller (80) determines if any of said determined metric values indicates the occurrence of a misuse event. The controller also determines if a pedestrian/vehicle impact event is occurring by comparing the metric value of at least one sensor signal against a selectable threshold. An actuation signal is provided in response to the comparison. The selectable threshold is selected in response to the determined occurrence of a misuse event. An actuatable pedestrian impact mitigation device (84) is attached to the vehicle and is actuated in responsive to the actuation signal from said controller.
摘要:
An apparatus for controlling an actuatable occupant restraint device of a vehicle comprises a central crash accelerometer that senses crash acceleration at a vehicle location and that provides a first crash acceleration signal indicative thereof. A side pressure sensor senses pressure in a chamber disposed at a side of the vehicle and provides a side pressure signal indicative thereof. A controller actuates the actuatable occupant restraint device in response to the first crash acceleration signal and the side pressure signal. The controller determines a first moving average of acceleration value comprising a moving average of acceleration in a direction generally perpendicular to a longitudinal axis of the vehicle determined from the first crash acceleration signal. The controller determines a change in pressure value comprising a change in pressure in the chamber determined from the side pressure signal. The controller actuates the actuatable occupant restraint device when both the first moving average of acceleration value exceeds a first threshold and the change in pressure value exceeds a second threshold.
