摘要： A passive safety device (62) is triggered for protecting vehicle passengers in the event of a collision. The output signals of a signal acceleration sensor (1) are integrated to form a signal which triggers the deployment of the safety device when a threshold value for the integrated signal is exceeded and simultaneously additional criteria are met. These conditions are met in a simple circuit with a single acceleration sensor (1), so that the entire apparatus including the safety device (62) can be installed compactly in a steering wheel of a motor vehicle. In addition to a first signal evaluation channel in which the sensor signal is integrated once, there is at least one second signal evaluation channel including two integrators (20) and (23) in which the sensor signal is integrated twice to provide a distance signal that is evaluated by a further threshold value switch (24). The safety device (62) is only triggered if both the singly integrated signal and the doubly integrated signal exceed prescribed thresholds within a prescribed time period. Additionally, a rear collision impact recognition circuit and a hammer blow impact recognition circuit (31 to 36; 41, 28) is provided to block the triggering of the safety device. A rest circuit is also provided.

摘要： A crash sensor is constructed for triggering a passive safety device, such as an air bag or a seat belt tightening device. The crash sensor is capable to distinguish between different types of impacts such as front impacts, rear impacts, side impacts, and minor impacts, for example occurring in a repair shop. For example, the air bag shall be deployed only in response to a frontal impact. The crash sensor has at leasst two acceleration sensors having sensitivity axes arranged at different angles relative to the longitudinal vehicle axis or travel direction. The output signals of the acceleration sensors are integrated in respective integrated circuits and supplied to a threshold value circuit which in turn provides the necessary signal for activating a trigger circuit. Each signal processing channel is equipped with at least two parallel threshold value switches which cooperate with signal validating or signal recognizing circuits to distinguish between different impacts for permitting the deployment or for preventing the deployment of the safety device. The trigger circuit itself is also a logic circuit in which the individual inputs are received through input conductors carrying signals representing the various criteria for the deployment or prevention of the deployment of the safety device. Thus, the safety device is deployed only if a frontal impact has been recognized.

摘要： An impact sensor for detecting a collision of a motor vehicle or the like has at least two acceleration detectors, and a signal evaluating circuit for each detector for evaluating the output signals of the respective acceleration detectors. The evaluated signals are passed through a logic signal interpreting circuit to provide a control signal for triggering passive safety devices such as an inflatable air bag. In order to trigger the passive safety devices as quickly as possible in response to an impact or collision, and in order to determine the angular direction of the impact, several acceleration detectors having oriented sensitivity axes are provided, whereby the sensitivity axes of separate detectors are oriented in different directions. The signal evaluation and interpretation to provide the triggering signal make sure that only determined output signals of the acceleration detectors cause the intended triggering preferably only for frontal impact collisions.

摘要： A method and apparatus for recognizing a crash, in a vehicle by measuring vehicle speed change continuously within a limited time periods and comparing the measured values with those determined in prior time periods. Acceleration can be differentiated out by means of the above-mentioned process/arrangement and can be evaluated if, in the case of a high-speed and low-speed crash, it should not be possible to differentiate sufficiently by means of the partial speed difference. Different partial speed differences (by means of observation periods of different durations) can be measured and compared in order to permit ignition in the case of slower (oblique) crashes only within a limited time window in the initial phase of the crash.

摘要： A device for triggering a passive safety system in a vehicle upon detection of an impact. At least two acceleration sensors, the sensitivity axes of which are aligned for detecting an angle of a frontal impact, are each assigned to a signal channel which, in series with the respective impact sensor, comprises an evaluation circuit, particularly an integrator circuit for its output signals, and a threshold value circuit. During the formation of the speed integral, the physical signal course and the course of the signal edges is evaluated by several logic units in a logical unit (LOG) in order to obtain factors which influence the integration constant of integrators (by multiplication and reduction) to enlarge the area that can be evaluated.

摘要： The invention concerns a method for the recognition of insulation defects in a circuit adapted for connection to a low-ohmic current source or sink having off-load voltage U.sub.n0, Towards this end the circuit is initially subjected, in a separated state, to a diagnostic voltage from a current limited current source or sink whose off-load voltage U.sub.h0 corresponds to exceeds or, respectively, is less than the voltage U.sub.n0. A decision is made as to the presence or absence of an insulation defect based on the current and/or voltage dependence during application of the diagnostic voltage. Finally, in the event that a defect is present, an error message is issued and the low-ohmic current source or sink is not connected to the circuit for self-diagnosis. Otherwise, the low-ohmic current source is connected to the circuit, or the sink, in sequential fashion for self-diagnosis testing. In this fashion even hidden insulation defects are recognized. The invention also concerns a system for carrying out this method.
