Abstract:
A system for insuring that an authorized air bag module (1) is installed within a vehicle. A vehicle processor (3) communicates with an air bag module processor (2) via transmission line (4). The processors are programmed such that the vehicle processor (3) only recognizes a given authorized air bag module processor (2). If an unauthorized airbag module is installed within the vehicle, the vehicle processor (3) notifies the vehicle operator via indicator lamp (7). Alternatively, the vehicle processor (3) disables the vehicle when an unauthorized airbag module is installed.
Abstract:
A fuel supply controller includes a receiver unit that receives a collision signal, which indicates that a vehicle has a collision, transmitted from an external device, an engine stop detecting unit that detects a stop of an engine mounted on the vehicle, and a fuel supply stopping unit that stops a supply of a fuel to the engine when the collision signal is received by the receiver unit and the stop of the engine is detected by the engine stop detecting unit.
Abstract:
Bei der Erfindung wird das Auftreten eines starken Druckabfalles in einem Reifen (19), wie er insbesondere bei einem Reifenplatzer auftritt, erfasst und zur Ansteuerung eines reversiblen einem Sitz zugeordneten Systems, insbesondere einem Gurtstraffer, verwendet, um den Insassen in dieser potenziell gefährlichen Situation im Sitz zu fixieren. Das Erfassen dieses schnellen Abfalls kann darüber hinaus zur Anpassung von Auslöseschwellen anderer, reversibler und irreversibler, Rückhaltemittel verwendet werden.
Abstract:
A method and a control device for triggering person protecting means in a vehicle are proposed. In said method, the following successive, cyclically repeated steps are carried out: a transmission memory is filled with first triggering data from a previous cycle; at least one accident sensor signal is read; the first triggering data is transmitted from the transmission memory to a triggering circuit; a triggering decision is made in accordance with the at least one accident sensor signal; second triggering data is generated in accordance with the triggering decision.
Abstract:
The invention relates to a device for increasing the security of a motor vehicle comprising an automatic transmission (10), which is impinged upon by an electrical transmission control system (16) and a detection unit (22, 24, 26, 28) for detecting a critical driving situation and for generating a corresponding signal. In order to increase driving security, an evaluation device is provided which checks whether the generated signal has reached a specific value or exceeded a specific threshold. If said value has been reached or the threshold has been exceeded, the evaluation device causes the transmission control system (16) to interrupt the positive engagement of the transmission (10).
Abstract:
According to the invention, impact sensors are repeatedly interrogated during a polling mode and have to actively reply by emitting current pulses. If a sensor does not reply it is selectively addressed and can at that point signal a desired message. The master unit has full communications control over the bus so that data collisions can be avoided and very rapid transmission of the sensor signal is achieved. The master unit can change the communication priorities at any time.
Abstract:
A control device placed in or on a vehicle seat, comprising a sensor (41-45) to recognize seat occupant, a sensor (61-63) to recognize the position of the vehicle seat (1), a common control switch (21) and an energy supply (22) for the control switch (21), the sensor (41-45) for seat occupant recognition and the sensor (61-63) for position recognition of the vehicles seat (1) are electroconductively connected to the control switch (21).
Abstract:
The invention relates to a circuitry, especially for function modules which can be fitted in a motor vehicle with a power supply and/or connected to a control circuit. There is to be a central unit (12) containing at least one circuit (16, 36) for all the voltage and/or control signals which can be used by the function modules (22, 24, 26, 28, 30, 32, 40, 42, 44, 46, 48, 50, 52, 56, 58, 70, 72, 74, 76, 78, 80, 82, 84, 86, 88, 90, 96, 98) together for their conditioning and the central unit (12) can be connected to the function modules and the function modules can be interconnected via a bus system (62, 66).
Abstract:
Es wird ein Verfahren zur Datenübertragung zwischen zumindest einem Sensor und einer Zentraleinheit eines Fahrzeugsteuergeräts vorgestellt, wobei a) zwischen dem zumindest einen Sensor und der Zentraleinheit zumindest zwei zueinander parallele Datenübertragungskanäle vorgesehen sind und b) im Normalbetrieb über den ersten Datenübertragungskanal Daten erster Art über den zweiten Datenübertragungskanal Daten zweiter Art übertragen werden und c) bei Ausfall eines Kanals die Daten erster und zweiter Art über den noch intakten Kanal übertragen werden.
Abstract:
Es wird eine Vorrichtung und ein Verfahren zur Übertragung einer Ansteuerungsentscheidung für eine Aktuatorik von einem ersten zu mindestens einem zweiten Steuergerät vorgeschlagen, wobei das zweite Steuergerät die Aktuatorik in Abhängigkeit von mindestens zwei Nachrichten vom ersten Steuergerät ansteuert.
