摘要： In the restraint system, a central control unit and a plurality of data processing units are coupled to a bus line, each of the data processing units being provided to activate one or more restraint devices. In order to keep the restraint system operational to the extent possible in the event of a short circuit, each data processing unit measures for short circuits on the bus line and starts timing if a short circuit is detected. Each data processing unit has a circuit breaker, with which the bus line can be closed or interrupted. This circuit breaker is opened if the short circuit measured is longer than a preset waiting time.

摘要： In an evaluation process for output signals of an acceleration-sensitive sensor in restraint systems for vehicle occupants, the output signals of the sensor are picked up and evaluated periodically. In a normal, uncritical operating state the evaluation occurs after relatively long intervals of time. If indications suggest a critical operating state, that is, an accident, however the evaluation of the output signals of the sensor occurs at shorter intervals of time.

摘要： A method of actuating a safety device for vehicle occupants, wherein the safety device has several tripping devices coupled to a capacitor and to passenger restraint devices, such as air bags, seat belts, or the like. The energy supplied by the capacitor to a tripping device is measured upon actuation of that device. If the energy supplied exceeds a predetermined limit, the flow of electric current from the capacitor to the respective tripping device is interrupted. Thus, if an actuated tripping device shunts, the energy of the capacitor is not drained by the shunt, and the capacitor maintains an energy level sufficient to actuate the other tripping devices.

摘要： To prevent spurious operation of a controlled operating element (12), typically a safety element which can be irreversibly triggered, such as a trigger or firing cartridge of a passenger restraint airbag, while providing for reliable operation in case of a crash of a vehicle in which the airbag is installed, a control signal is derived from a computer (10) processing input signals. The transmission of the control signals from the computer (10) to the operating element (12) is through a time delay stage (30) which has a time delay of sufficient length to permit the computer to correct, if necessary, signals from its output (16) and to carry out tests on the output signals from the computer apparatus. An evaluation circuit (18) continuously compares the output signals with check values. The check values may be derived from, for example a second computer similar to the computer, or from stored representative values. If the comparison indicates coincidence, the operating control signal from the computer is transmitted to the operating element (12). If, however, e.g. due to extraneous disturbances, a deviation between the test samples and the signals derived from the output (16) of the computer indicates a deviation, transmission of the control signals from the computer (10) to the operating element (12) is prevented, and the computer is controlled to repeat its computation, or part of a computation cycle.

摘要： To permit rapid checking of possible malfunctions or erroneous computations in data processing cycles, in which a plurality of computer units carry out processing of data, especially to supervise and control safety apparatus, each one of the units generate intermediate information data at predetermined time intervals, which intermediate information data are transmitted to each one of the other units. The so-received intermediate information data are buffer-stored and compared in all the units with locally generated check data. If the comparison indicates coincidence, computation is continued through subsequent processing cycles; if an error is detected, at least that computer unit which processes the data erroneously is reset to repeat at least the preceding computation cycle, and the unit which detected the error is placed into a "set-and-hold" mode. The intermediate information data may be derived, for example, in form of a quotient of a beginning and terminal address; additionally, the time of arrival of the intermediate information data can be checked against a time marker, thereby detecting and providing for correction of both computation as well as timing errors.

摘要： A capacitor (12) which, by its charge or discharge, times the interval between successive signals at a computer output point which is being monitored so as to provide a reset signal to the computer when the interval exceeds a predetermined normal value, is held in a charge condition which produces a reset signal to the computer component, for a predetermined time after power is turned on. In one embodiment a transistor in circuit with resistances and another capacitance is used for that function and in another embodiment an additional comparator responsive to the rise of the supply voltage up to a threshold value provides that function. The circuit can be designed to provide reset signals of either logic value (0 or 1).

摘要： Repetitive processes in internal combustion engines which are dependent upon the values of particular parameters are controlled either by a main computer or an auxiliary computer. Switching from the main to the auxiliary computer takes place if a sequence error detecting stage detects errors in the desired alternation between the main control signals furnished by the main computer and reference mark signals indicative of predetermined angular positions of a shaft of the engine. Specifically, the system is switched to operate under control of the auxiliary computer if such an alternation error occurs again within a predetermined number of cycles. The switching can also take place as a result of missing reference mark signals and as a result of the absence of monitoring signals indicative of correct operation of the main computer program.
