    摘要： A collision detection device for a vehicle includes a first direction signal outputting unit which detects an intensity of heat ray radiated from a detection object which is near or contacts the vehicle to outputs a first direction signal, a second direction signal outputting unit which detects ultrasound wave sent by a sending member and reflected by the detection object to output a second direction signal, an impact signal outputting unit which detects an impact on the vehicle to output an impact signal, and a control unit. The control unit determines an occurrence of a collision between the vehicle and a human, in the case where it is determined that a difference between the first direction signal and the second direction signal is within a first predetermined range and the impact signal is outputted.

    摘要： A method is disclosed for managing variation in acceleration values obtained from a vehicle acceleration sensor for use in on-board computer based crash evaluation algorithm. Sources contributing to the variation are identified and a determination is made of the magnitude of the variation from each source to a selected multiple of a standard deviation, for example, 3 to 6 null. The variation for each source is suitably combined to produce a database of acceleration-time history with the combined variations for use in calibrating and or validating a candidate crash algorithm.

    摘要： A passenger-protecting device such as an air-bag system is activated upon detection of a vehicle lateral inclination angle exceeding a predetermined critical level. Such detection is performed by a lateral inclination detector having a pair of gravitational acceleration sensors for detecting a static road inclination and an angular velocity sensor for detecting a dynamic roll angle of the vehicle. Sensing directions of the pair of gravitational acceleration sensors are positioned to cross each other with a right angle and to make an angle of 45null with respect to a vehicle floor. The dynamic roll angle is calculated by integrating outputs of the angular velocity sensor. The vehicle inclination angle is obtained to summing up the static inclination angle and the roll angle. The passenger-protecting device is timely activated to protect passengers from overturn impact of the vehicle.

    摘要： A system and method for triggering a vehicle safety device in response to a crash or sudden vehicle deceleration includes conversion of an analog signal generated by an acceleration sensor and representative of instantaneous vehicle acceleration to a digital value and using a ROM lookup table to determine its natural log. An autocorrelation of the log values of the acceleration data is determined and thereafter used to calculate first and second basis vector values. A safety device trigger signal is generated by a signal space discriminator when a value calculated from the first and second basis vector values exceeds a threshold value therefor.
