    摘要: A method of checking the functional reliability of a pressure sensor, the air pressure being detected inside a vehicle body part, the vehicle having at least one additional pressure sensor for detecting the air pressure. With the help of the method, it may be possible to determine the integrity of the sensor without requiring any additional auxiliary equipment. To do so, the measured values of the pressure sensor and the measured values of the at least one additional pressure sensor are compared over a defined observation period. The pressure sensor is recognized as being defective if its measured values deviate by more than a predefined amount from the measured values of the at least one additional pressure sensor.

    摘要: The invention relates to a safety system for motor-vehicle occupants, in particular a restraint system, such as an airbag, belt tighteners, etc., which has at least one tripping sensor that exhibits a response time, one processing unit, and one final firing stage for activating the safety system. To protect against spurious tripping, an inhibiting circuit (21) is proposed, which is triggered by the processing unit (2). It cancels an interlock of the final firing stage (5) only after an interlocking enable time (t.sub.v) has elapsed, whereby the interlocking enable time (t.sub.v) is shorter than the response time (t.sub.a) of the tripping sensor (1).

    摘要: The invention relates to a microprocessor circuit arrangement having a watchdog circuit, which monitors the proper program flow for the processor and which must be triggered in specific time intervals by the microprocessor, since otherwise it will reset (reset function) the microprocessor to the program start or the like. For reasons of simplification, it is proposed that when the microprocessor (2) recognizes that a malfunction has occurred, it spuriously triggers the watchdog circuit (5) in a selective manner to release a reset function coming from the watchdog circuit (5).

    摘要: A vehicle occupant safety system, in particular a restraining system such as an airbag, safety-belt tightener or the like, includes a sensor device having at least two sensors, a preprocessing device comprising at least two preprocessing circuits, for the sensor signals, a computing system and a trigger circuit including at least two stages, for a safety device. For providing a high degree of safety with relatively low costs, the computing system is constructed as a single-computer system in such a way that it processes the data of two preprocessing circuits in two programs with staggered timing with respect to one another.
