摘要： An arrangement is presented for an actuation system of a passenger protective device for a motor vehicle. The system is equipped with a storage device to successively input a newer acceleration signal from an acceleration sensor at every division period obtained by dividing a measurement period so as to store and update a plurality of the latest acceleration data for the measurement period. The plurality of stored latest acceleration data are summed to obtain an integration value at the measurement period. The system compares this integration value with a predetermined value to detect a collision state of the motor vehicle. When detecting the collision state of the motor vehicle, the system actuates the passenger protective device. This system arrangement can improve the vehicle collision decision accuracy.

摘要： When an acceleration sensor is used, it is attached to a measured object to detect an acceleration applied to the object. The acceleration sensor includes a package having at least one chamber. A sensor element is disposed in the chamber and has a portion which vibrates in response to the acceleration. Damping liquid is sealed within the package and has a quantity which allows the sensor element to be submerged in the damping liquid and which allows a predetermined quantity of gas to remain in the package. The gas absorbs a thermally-induced volume change of the damping liquid. In the absence of the acceleration, a gas bubble is prevented from separating from the gas. In addition, the gas bubble is prevented from staying in the chamber.

摘要： A structure and method for enabling a passive vehicle occupant restraint to be activated at the earliest possible timing, irrespective of a type of a collision. A floor sensor measures a deceleration G applied to the length of a vehicle and outputs the deceleration as the measurement G. An arithmetic unit carries out a predetermined arithmetic operation on the measurement G output from the floor sensor, so as to determine a function f(G). A conditional activation unit has a variation pattern of a threshold value T that varies with a variation in velocity v of a non-stationary object. The conditional activation unit reads a threshold value T corresponding to an input velocity v from the variation pattern and compares the threshold value T with the value of the function f(G). In case that the value of the function f(G) exceeds the threshold value T, an activation signal A is input to a driving circuit. A satellite sensor outputs an ON signal when a deceleration of not less than a predetermined reference value is applied to the vehicle. A threshold variation pattern selection unit changes the variation pattern of the threshold value T against the velocity v used in the conditional activation unit to another variation pattern, in response to the ON signal output from the satellite sensor.

摘要： A floor sensor 32 measures a deceleration G applied to the length of a vehicle and outputs the deceleration as the measurement G. An arithmetic unit 58 carries out a predetermined arithmetic operation on the measurement G output from the floor sensor 32, so as to determine a function f(G). A conditional activation unit 60 has a variation pattern of a threshold value T that varies with a variation in velocity v of a non-stationary object. The conditional activation unit 60 reads a threshold value T corresponding to an input velocity v from the variation pattern and compares the threshold value T with the value of the function f(G). In case that the value of the function f(G) exceeds the threshold value T, an activation signal A is input to a driving circuit 34. A satellite sensor 30 outputs an ON signal when a deceleration of not less than a predetermined reference value is applied to the vehicle. A threshold variation pattern changing unit 42 changes the variation pattern of the threshold value T against the velocity v used in the conditional activation unit 60 to another variation pattern, in response to the ON signal output from the satellite sensor 30. This structure of the present invention enables a passive vehicle occupant restraint to be activated at the earliest possible timing, irrespective of a type of a collision, in which the vehicle crashes.

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.
