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.

摘要： A trigger circuit for occupant protection systems in motor vehicles comprises a control unit which will effect the triggering of a means of restraint such as an airbag, depending on sensor signals generated by one or more external sensor units. To achieve a degree of triggering certainty, data interrogation must take place in very short time intervals. A safe transmission of data between the control unit and the sensor units will be ensured if, in accordance with this invention, the information units to be transmitted will each be encoded by means of a PWM signal with a certain period duration. The control unit will check the period duration of the PWM signal received, and, in the event of this actual period duration not matching the specified nominal value, it will not accept the relevant unit of information.

摘要： A data transmission method in a real-time data processing system, comprising a control unit and at least one function unit linked to this control unit through a data line, is described that permits noise-free and noise-insensitive transmission of data. In accordance with the invention, the data is stored in a buffer memory made up of a shift register and an intermediate storage, before being loaded into a main memory of the function unit. Transfer to the intermediate storage takes place only if certain conditions are satisfied that identify transmission faults. Before the data is stored in the main memory, the data is read-back into the control unit memory for the purposes of checking and there it is compared with the original data. If there is no correspondence, data transmission is performed again. The method in accordance with the invention can be applied advantageously in local networks, and in particular for motor vehicles, where a central control unit is applied for controlling operational sequences through various function units such as triggering circuits for passenger restraint systems or control circuits concerning motor management.

摘要： Increasingly, motor vehicles are being equipped with safety systems for vehicle occupants and where these safety systems are controlled by electrically actuated triggering means such as ignition pills for airbags that in turn are controlled from an output stage. The invention demonstrates a method that ensures safe and uninterrupted operation of these triggering means and which protects the output stage from being destroyed should a fault occur as a result of, for example, an ignition pill by-pass.

摘要： To trigger driver and passenger airbags as well as side airbags, the sensor signals generated by collision sensors will be fed into a central control unit for processing. According to this invention, side airbags will be activated by evaluating sensor signals generated by a collision sensor for detecting head-on and side collisions, centrally located within the motor vehicle, as well as by a left-hand and right-hand collision sensor each detecting side collisions, by the control unit generating a triggering signal whenever the centrally located collision sensor and at least one of the two side collision sensors generate a collision signal, with one of these two collision sensors having a greater value, or if the centrally located collision sensor as well as one of the two side collision sensors provide a signal of equal value, with the other side collision sensor simultaneously generating a collision signal with a value either equal or lower than the value of the collision signal generated by the central collision sensor. The process according to this invention will lead to a very high degree of triggering certainty for the entire occupant protection system, and advantageously does not require the use of a mechanical safety switch to trigger the side airbags.

摘要： This invention concerns a test procedure for a safety system in motor vehicles, in particular occupant protection devices such as airbag, belt tightener, or roll bar sensors. As a rule, the associated safety-critical circuit components of such safety systems will be monitored by additional and separate monitoring processors. According to this invention, a test procedure for these safety-critical circuit components requires little expense and which, using a simple-to-implement monitoring unit, will allow the same test quality to be achieved as with an independent monitoring computer.
