Definitions
- the present invention relates to a motor vehicle according to the preamble of claim 1.
- the motor vehicle locking system has a control device and a motor vehicle lock.
- the motor vehicle lock is designed as a so-called electric lock, in which by means of an electric drive, a pawl for opening a rotary latch of the motor vehicle lock can be lifted.
- the pawl is assigned as a sensor for detecting the state of the pawl a microswitch, which is formed as needed as a changeover switch and connected to the control device.
- the known motor vehicle locking system further comprises a handle, in particular an outside door handle on.
- the handle is assigned as a sensor for detecting an operation, a micro-switch, which is designed as a changeover switch and connected to the control device.
- the present invention has for its object to provide a motor vehicle with increased security against failure or malfunction, in particular against interruption of the electrical connection between a sensor and a control device for transmitting sensor signals to the control device.
- a sensor for transmitting sensor signals to the control device.
- the detection of the failure or the malfunction and on the other hand ensuring the desired function despite the failure or malfunction of interest.
- a basic idea of the present invention is to provide a sensor - in particular in a motor vehicle locking system - for the transmission of sensor signals with two electrically independent outputs and to connect the outputs via electrical signal lines to the control device.
- it is initially possible in principle to detect a fault condition by means of the control device. If, for example, sensor signals which are not compatible with one another are transmitted to the control device via the outputs of the sensor, this can be detected by the control device.
- the sensor signals of a sensor are compatible in the present sense, if they are in a normal "predetermined" predetermined relationship to each other. In the simplest case, the sensor delivers identical sensor signals at its outputs, so that a deviation of the sensor signals from each other is a sure sign of a malfunction of the sensor.
- the proposed solution it is also possible that even if one signal line fails, the sensor signal via the other signal line to the control device is still transferable and evaluable by this.
- the proposed solution thus not only allows the detection of a failure or malfunction, but ensures proper operation even in the event of failure or malfunction.
- the senor is assigned to an operating element, such as a door handle, a handle, a control lever or the like, on a motor vehicle door in order to detect an actuation of the operating element and, if necessary, to initiate an opening of an associated motor vehicle lock based on the respective sensor signals ,
- an operating element such as a door handle, a handle, a control lever or the like
- the senor can also be assigned to the motor vehicle door lock itself or arranged in this housing. Again, the proposed solution again u. a. prevent interruption of the transmission of the sensor signals and thus increase the reliability of the motor vehicle locking system and the motor vehicle as a whole.
- the sensor for this purpose has two electrically independent inputs, which are - for example, switching - coupled or connected to the outputs and connected via separate supply lines to a power supply.
- two electrically independent inputs which are - for example, switching - coupled or connected to the outputs and connected via separate supply lines to a power supply.
- the senor for generating sensor signals on at least two sensor modules, wherein the sensor modules preferably each operate on different sensor principles of action.
- the advantage of such a configuration of the sensor is that the two sensor modules are designed differently so that they each different - or at least partially not at all - respond to certain disturbing influences. This minimizes the likelihood that when a certain disturbance occurs, both sensors will simultaneously malfunction. Overall, this increases the reliability even in unfavorable environmental conditions.
- the above-described concept of increasing the security by redundancy is extended to the control device.
- Essential here is the parallel evaluation of the signals generated by the sensor such that a failure or malfunction can be detected by differing or incompatible evaluation results readily from the controller.
- the control device has a first evaluation unit and a further evaluation unit which is independent of the first evaluation unit, wherein the control unit evaluates the sensor signals generated by the sensor substantially in parallel by both evaluation units and based on this evaluation controls signals to a consumer, such as the electrical Drive a pawl - opening drive - outputs.
- the evaluation units each take over the original function of a conventional control, namely the "reading in” of sensor signals, the generation of an evaluation signal assigned to the respective sensor signal and the output of the evaluation signal.
- the control device may be equipped with further components in order to determine whether the evaluation signals are compatible with one another or whether there is a malfunction, for example, of one of the two evaluation units.
- a high level of security can be achieved, in particular, if the two evaluation units are largely independent of one another. In the case of an at least partially software-implemented control device, this can be supported by assigning different memory areas of a microcontroller or the like to the two evaluation units are. It is optimal, however, if the two evaluation units are each realized at least partially in separate hardware.
