Abstract: A battery inspection device inspects for internal short circuits in a battery. The conditions of battery modules B are inspected by measuring open circuit voltage signals of the battery modules that form a battery stack. The open circuit voltage signals are supplied to a detection circuit through voltage signal lines each prepared for each battery module. A voltage signal line and an address signal line A for passing an address signal to set an address which identifies the battery stack using a signal supplied from a signal source share a single line extending between the battery module and the detection circuit, and thus the number of signal lines is reduced.

The left and right deceleration detectors are located at left and right front portions of a vehicle for detecting decelerations at the left and right front portions, respectively. The arithmetic unit calculates the decelerations detected by the deceleration detectors to obtain arithmetic results with respect to the left and right portions of the vehicle.

The decision unit compares the average with a threshold and decides whether a collision type of the vehicle is a symmetric or asymmetric on the basis of the comparison.

Abstract: An acceleration detector including a mass member and a fixed contact, which keep contact with each other by an elastic member that presses the mass member to the fixed contact. When a vehicle undergoes an impact from its left side in its traveling direction, for example, and the mass member receives inertial force that exceeds the pushing force of the elastic member, the mass member moves toward the elastic member, thereby separating from the fixed contact. By providing the mass member and the fixed contact on both sides of the elastic member, side-to-side impact applied to the vehicle can be detected. The acceleration detector with such a configuration can detect the impact acceleration at high response sensitivity and in both directions.

Abstract: A first reference-value is preset, the first reference value being a minimum value of a physical quantity detected by a car compartment sensor within a range where destruction of a sensor 2a or a sensor 3a disposed in the crushable area could occur as a result of the shocks applied in the crushable area. The sensor output detected by the sensor 2a or the sensor 3a is invalidated, when a physical quantity of the-sensor output detected by the car compartment sensor 6a in the safety area as a result of the shocks applied in the crushable area exceeds the first reference value, so that the erroneous determination according to the sensor 2a or the sensor 3a is avoided. A highly reliable determination as to whether a collision necessitates activation of an air bag device results.

Abstract: A discrimination is made between a soft crashing in which a relatively low acceleration signal continues for a long period of time and a low-speed head-on crashing so that an air bag can be started at an appropriate timing. An occupant protecting apparatus for that purpose is made up of: a first comparator for comparing an output signal of an acceleration sensor which detects an impact at the time of crashing of a vehicle and a first threshold value; a second comparator for comparing an integrated value of an integrator which integrates an output of the first comparator within a predetermined section and a second threshold value while making a shift by a unit time within a predetermined section; and a starting device for controlling the starting of the air bag based on an output signal of the second comparator.

Abstract: The setting of a sensitivity of an acceleration detection device is performed by regulating the characteristics of a compression coil spring such as an initial load or a spring constant of the compression coil spring and by regulating the dimension of a mass body in an axial direction of a slide shaft.

Abstract: A crash detection apparatus of a vehicle includes acceleration sensors mounted on different positions of a vehicle, each for detecting an acceleration at its position. A crash mode identifying section identifies a crash mode of the vehicle in accordance with a time difference between timings at which integral values obtained by integrating the individual acceleration signals supplied from the acceleration detectors exceed a threshold value. In accordance with the crash mode, a reference threshold value of a comparator for making a crash decision is determined. This makes it possible to implement a crash detection apparatus of a vehicle capable of making a responsive crash decision even in an asymmetric crash in which only one side of the vehicle is deformed and the occurrence of a large acceleration signal is delayed.
