摘要： A satellite sensor and a floor sensor are provided in a forward portion and a central portion, respectively, of a vehicle body. A calculated value and a speed are determined through predetermined processing of a deceleration detected based on an output signal of the floor sensor. If a value determined from the relationship between the calculated value and the speed exceeds a predetermined threshold changing pattern, an airbag apparatus is activated. The threshold changing pattern is set by selecting a map from a Hi map, a Lo1 map, a Lo2 map and a Lo3 map based on a deceleration determined from an output signal of the satellite sensor. If a map different from the current map is to be set as a threshold changing pattern, the threshold changing pattern is set to the desired map after a state that allows the map to be set continues for a time corresponding to a difference between the two maps.

摘要： An activation control apparatus of an air bag system of a motor vehicle includes a first sensor disposed at a predetermined position within a vehicle body, for generating a signal indicative of an impact applied to the vehicle, and at least one second sensor disposed frontwardly of the position of the first sensor, for generating a signal indicative of an impact applied to the vehicle. The control apparatus is operable to activate an air bag device when a parameter determined based on the output signal of the first sensor exceeds a predetermined threshold pattern that is determined based on the output signal of the second sensor. When the predetermined threshold pattern is changed from a reference pattern to a desired threshold pattern that provides lower threshold values, the pattern is changed step by step at predetermined time intervals, without skipping an intermediate pattern or patterns between the reference pattern and the desired pattern.

摘要： An apparatus for controlling an output of an air bag device (30) such that the output is made relatively high when a deceleration value (GF) detected by a floor sensor (14) disposed in a central portion of a vehicle body is higher than a threshold which changes with a velocity (∫GF·dt) which is obtained as a time integral of the deceleration value (GF). The threshold is changed from a normally selected high value to a low value when one of two deceleration values (GSL, GSR) detected by respective two satellite sensors (16, 18) disposed in front left and right portions of the vehicle body has reached a threshold value which changes with the velocity (∫GF·dt).

摘要： Satellite sensors (16, 18) that output level signals corresponding to an impact on a vehicle (10) are provided right and left portions of a forward portion of the vehicle (10), separately from a floor sensor (14). If a map (Lo1, Lo2, Lo3, Hi) selected as a threshold changing pattern from an impact (deceleration) detected based on the output signal of one of the satellite sensors (16, 18) and a map (Lo1, Lo2, Lo3, Hi) selected as a threshold changing pattern from an impact (deceleration) detected based on the output signal of the other satellite sensor are different from each other, the map of a smaller threshold is selected from the maps based on the output signals of the two satellite sensors (16, 18), and is set as a threshold changing pattern for determining whether to activate an airbag apparatus (30).

摘要： A rollover determining apparatus and methods for determining whether a vehicle is about to roll over distinguishes a type of rollover that is likely to occur to the vehicle based on the lateral acceleration of the vehicle and the roll angle of the vehicle. Moreover, a determination is made whether the state of the vehicle indicated by a first quantity corresponding to the distinguished type of rollover is in a rollover region determined by a predetermined threshold line. The apparatus and methods can also change the threshold line in accordance with the magnitude of second quantity that is different from the first quantity and that corresponds to the distinguished type of rollover.

摘要： Systems and methods for controlling a vehicle-occupant protecting apparatus provided on a vehicle such that the apparatus is controlled upon determination that the vehicle has had a rollover motion, the control system including a first detector that determines whether the vehicle has crashed, a second detector that determines whether the vehicle has had a rollover motion, and an invalidating device that invalidates the determination by the second detector that the vehicle has had the rollover motion such that the determination by the second detector is invalidated for a predetermined time after the determination by the first detector that the vehicle has crashed. Furthermore, a controller controls the vehicle-occupant protecting apparatus based on outputs of the second detector and the invalidating device to prevent unnecessary operation of the vehicle-occupant protecting device.
