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： A collision severity determining system for determining severity of a collision of a vehicle includes a first deceleration detector disposed in a central portion of a vehicle for detecting a deceleration in a longitudinal direction of the vehicle, and a second deceleration detector disposed in a front portion of the vehicle for detecting a deceleration in the longitudinal direction. A controller calculates a velocity change amount of the vehicle by integrating the vehicle deceleration with respect to time, and determines severity of the collision by comparing the vehicle deceleration with a threshold value corresponding to the same velocity change amount. When a problem, such as a failure or breakdown of the second deceleration detector, occurs, the severity determining unit operates in a predetermined fail-safe mode for selecting an appropriate severity determination map stored in the controller, and makes a severity determination based on the selected severity determination map.

摘要： A load detecting sensor includes a first member, a second member, and an optical fiber. The first member has a groove having a bottom portion and a column portion which defines the groove. The second member covers the groove of the first member so that a surrounded space is formed. The optical fiber is arranged in the surrounded space. At least one of the first member and the second member is made of an elastic body. The surrounded space is deformable when load is applied to at least one of the first and the second members. When load is applied to at least one of the first and the second members, the deformation of the optical fiber is caused following the deformation of the surrounded space. Hereby, the load detecting sensor, which can decrease the manufacturing cost and increase the detecting sensitivity by the optical fiber, can be obtained.
