    摘要： A collision type identifying device is disposed in a central portion of a vehicle main body and has first deceleration detecting means (22), peak time detecting means (32), required time detecting means (34), and type identifying means (36). The deceleration detecting means (22) detects a vehicle deceleration in the longitudinal direction. The peak time detecting means (32) detects, as a first peak time (tp), a time from the excess of a preset threshold (GTH) by a waveform of the vehicle deceleration (G) detected by the deceleration detecting means (22) to a first peak. The required time detecting means (34) detects, as a required time (tn), a time when an integrated deceleration (VG) obtained through time quadrature of the vehicle deceleration (G) becomes equal to a predetermined integrated value set in advance. The type identifying means (36; 78) identifies a vehicle collision type on the basis of the first peak time (tp) and the required time (tn). The collision type identifying device can identify a vehicle collision as one of a plurality of collision types at once.

    摘要： A vehicle collision decision apparatus determines whether or not an occupant-protecting apparatus should be started in a collision by an occupant moving characteristics determining device. Also, whether or not the collision continues is determined in an acceleration change determining section. A determining threshold for a frequency component which indicates a damage to the vehicle which is calculated in a frequency component calculating device is selected. The occupant-protecting apparatus is activated appropriately by monitoring the damage to the vehicle in the frequency component determining device 19 by using the frequency component. By doing this, a vehicle collision decision apparatus which can determine the determining the condition in the vehicle collision appropriately is provided.

    摘要： An apparatus includes an accelerometer (24) for providing an analog acceleration signal indicative of crash acceleration. A sigma-delta A/D converter (26) is operatively connected to the accelerometer (24) for providing a pulse-width-modulated gate enable signal (GES) with a value indicative of the acceleration signal. The GES signal is ANDED with a clock signal to produce a pulse-density signal (CNT) indicative of the acceleration signal. A monitoring circuit determines (i) whether at least one pulse-density signal occurs when a gate enable signal is HIGH (FLAG 1), and (ii) whether the pulse-density signal occurs when the gate enable signal is LOW (FLAG 2). Other embodiments test to see if the gate enable signal is either full scale ON (FLAG 3) or full scale OFF (FLAG 4) by using a second crash sensor (64). Timing circuits (302, 316) are used to ensure that the pulse duration of at least one pulse-width modulated gate enable signal is greater than predetermined value within a predetermined time period.

    摘要： A vehicle restraint system that includes an impact sensor for sensing a vehicle impact to provide an electrical impact signal, an occupant restraint such as an air bag to restrain motion of a vehicle occupant, and an electronic control circuit responsive to the impact signal for operating the occupant restraint. The impact sensor includes a permanent magnet axially slidable within a linear cavity and resiliently biased to one end of the cavity, such that vehicle impact forces on the sensor urge the magnet to slide axially toward the opposing end of the cavity against the biasing forces. A magnetic sensor is disposed adjacent to the cavity and is characterized by providing the electrical impact signal as an analog electrical signal that varies in magnitude as a continuous monotonic function of axial position of the magnet within the cavity. The electronic control circuit is responsive to the impact signal for analyzing magnitude, slope and duration of the impact signal in order to predict necessity for activating the restraint system, and activating the restraint system when the magnitude slope and duration of the impact signal meet predetermined signal conditions or criteria.

    摘要： A two-step deployment control method for a supplemental inflatable restraint (SIR) in a vehicle. The deployment decision includes a "time to wait" step in which the control determines "when to deploy", and a "severity" step in which the control determines "whether to deploy". The "time to wait" step is based on an estimation of occupant displacement due to the crash, and the "severity" step is based on an estimation of the crash severity. The control method is modified to initiate earlier deployment when the acceleration data is indicative of a localized impact which does not involve the full front structure of the vehicle, such as an angle or pole impact.

    摘要： A trigger procedure for a restraint system for protection of the occupants in a vehicle, where short-time spectral analyses of at least one acceleration component of the vehicle structure are continuously implemented and at least one parameter characteristic for the deformation of the vehicle structure (trigger parameter) is calculated from several spectral components. The calculated trigger parameters are compared with one or more preset threshold values to make a decision on triggering of the restraint system.
