Definitions
- the present invention relates to the field of vehicle locking systems and relates to a method for detecting a closed position of a movable part of a vehicle according to the independent method claim, a computer program product according to the further independent claim and a vehicle locking system according to the independent system claim.
- Vehicle locking systems are generally used to securely lock a moving part of a vehicle and to unlock it accordingly. It is therefore a matter of vehicle safety systems that must function reliably to protect the occupants of the vehicle. According to the prior art, it is usually queried via door contact switches whether a moving part of the vehicle is properly locked and / or closed.
- the signals from the door contact switch are z. B. implemented in optical and / or acoustic Flinweise so that an open and / or unlocked door can be identified.
- switches can be integrated into corresponding vehicle locks of the moving parts.
- a method is known from DE 10 2010 052 582 A1 in which an open position of the door is recognized by means of a door contact switch.
- the door contact switch is queried, which means that it is recognized whether the door has been opened.
- a method for recognizing a locking state that emits a visual warning message when the door of a vehicle is not locked, a door contact switch on the B-pillar or on the door hinge delivering a corresponding signal.
- the disadvantage of the prior art is that the known systems can be manipulated by the simplest means. For example, it is possible to intentionally or unintentionally operate door contact switches from the outside even though the door is not locked. Furthermore, the locking mechanism of a vehicle lock can be brought into the locked state from the outside, although the door has not collapsed into the lock holder. In this way, a locked door would be simulated for the vehicle, which in reality is not locked at all.
- the problem is of particular importance in the case of vehicles that can be operated automatically, in particular in the case of driverless vehicles.
- the object of the invention is to at least partially remedy the disadvantages known from the prior art.
- it is the object of the present invention to enable reliable detection of a closed door, which offers improved protection against manipulation.
- a method for recognizing a closed position of a movable part of a vehicle, in particular a vehicle that can be operated automatically comprising the following steps: Receiving a first position signal from a first signal source as a first closing criterion, which indicates at least one locking position of a vehicle lock for the moving part comprised by a control unit;
- the control unit adds a conditional test instruction to the received first position signal, the conditional test instruction comprising checking for at least one second position signal as a second closing criterion after the detection of the first position signal, the first closing criterion still being met;
- the signal source differs from the first signal source and the second position signal can be assigned to the movable part
- the invention thus essentially makes use of a multiple factor, in particular a two-factor query that differs from one another Position signals, the signals originating from signal sources that differ from one another.
- a first position signal from a first signal source as a first locking criterion which comprises at least one locking position of a vehicle lock for the movable part, is received by a control unit.
- the locking position of the vehicle lock of or for the moving part is detected by a first signal source in the form of a position signal and interpreted as a first locking criterion for the moving part.
- the control unit can be a (higher-level) control unit of the vehicle, a lock control unit or a server. In any case, the control unit is signal-connected to the first signal source (wireless and / or wired).
- the control unit adds a conditional test instruction to the received first position signal, the conditional test instruction comprising checking for at least one second position signal as a second closing criterion after the detection of the first position signal, the first closing criterion still being met.
- the conditional test instruction is therefore only used when the first locking criterion is met, that is, the locking position of the vehicle lock has been recognized, to require at least one further locking criterion, the first locking criterion still having to be met. It is therefore not an OR link between two signals but an AND link. However, the first closing criterion must still be met when the second closing criterion is queried / checked.
- a second position signal is received by the control unit from a second signal source as a second closing criterion, wherein the second signal source differs from the first signal source and the second position signal can be assigned to the position, in particular the closed position, of the movable part.
- the second signal source is thus a source that differs from the first signal source.
- manipulation of the signals is at least made more difficult.
- the first signal source supplies a position signal which confirms the locking position of the lock
- the first locking criterion is verified by means of the second signal source, in which a further signal from another signal source is necessary.
- the second position signal could be independent of the locking position of the vehicle lock.
- the second position signal can also be assigned to the movable part, in particular the closed position of the movable part. It must therefore be able to be brought into relation to a position, in particular a closed position, of the movable part, so that a closed position of the movable part can be inferred.
- This can be, for example, the position of the movable part in relation to the body of the vehicle.
- the confirmation signal signals that the movable part of the vehicle is in the closed position.
- the confirmation signal can be an output signal, in particular an acoustic, optical and / or haptic signal (vibration).
- the output signal can be used to prevent or limit other vehicle functions. For example, starting the engine, driving off or accelerating can be influenced or other restrictions can be triggered that prevent or brake the vehicle.
- a movable part can be a side door, sliding door, wing door, flap, tank flap, charging plug flap, tailgate and / or a hood / front flap.
- the control unit can have at least one processing unit for processing signals or data, at least one memory unit for storing signals or data, at least one interface to a signal source and / or an output unit for reading in position signals from the signal source or for outputting data or control signals to the Output unit and / or at least one communication interface for reading in or outputting data, which are embedded in a communication protocol.
- the computing unit can be, for example, a signal processor, a microcontroller or the like, wherein the storage unit can be a flash memory, an EEPROM or a magnetic storage unit.
- the communication interface can be designed to read in or output data wirelessly and / or wired, a communication interface that can input or output wired data, for example, feed this data electrically or optically from a corresponding data transmission line or output it into a corresponding data transmission line.
- the control unit and / or computing unit is arranged outside the vehicle. It is advisable to use an IT infrastructure in the form of cloud computing or a similar network-based computer system. Such a solution can be advantageous in particular in the case of vehicles operated in an automated manner, since remote maintenance or remote control and monitoring is made possible. The risk of manipulation on / in the vehicle can be reduced.
- the control unit can be designed to execute a diagnostic routine. This makes it possible to check whether the signal source (s) is / are in an operational state or whether there are malfunctions. Depending on a diagnostic routine, it is possible to recalibrate the system if necessary, to reset system parameters or to display any errors so that maintenance is possible. It is thus conceivable that the associated measured values of a predetermined position, preferably the main notch, are stored and compared with one another, so that Deviations can be detected and conclusions can be drawn about possible malfunctions. During the product life cycle, changes, in particular caused by wear and tear or external environmental influences, can be recognized and included in the position determination. This increases the reliability of the position detection.
- the control unit can output an error signal if the first and / or second closing criterion is violated. If the first and / or second signal source does not send a position signal or if the control unit does not receive such a signal, the error signal can be used to identify that the closed position of the movable part is not present; H. could be verified / ensured. Accordingly, it can be determined not only that the movable part is in the closed position but also that the movable part is not in the closed position with certainty. It is also conceivable that the error signal makes it possible to determine the existing error source, that is to say which signal source does not supply a position signal.
- the control unit can determine a time interval between the first position signal and the second position signal as a first time criterion and compare it with a specified second time criterion, preferably stored in the control unit, and if the second time criterion is violated (deviates) from the first time criterion, the control unit output a corresponding error signal.
- the time check can be part of the conditional test instruction. This means that the time criteria are checked for compliance within the conditional test instructions. A different, in particular too long, time interval between the two position signals can indicate manipulation or an error.
- the first signal source is a locking sensor, in particular a locking pawl sensor, of the vehicle lock, which is preferred a locking position is detected and the locking pawl locks a rotary latch of the vehicle lock in the locking position.
- a locking sensor according to the invention can, for example, be inductive, capacitive, magnetic or optical sensors.
- microswitches or Hall sensors in particular can be used to detect the position of the locking mechanism, in particular a locking position.
- the locking position can preferably be a pre-locking and / or main locking position of the locking mechanism.
- the assumption of a locking position makes it possible to determine whether a lock holder of the movable part has come into engagement with the locking mechanism of the vehicle lock, so that a first locking criterion is mapped by the pre-locking or main locking position.
- the second signal source is a contact switch, in particular a contact switch that is not accessible from the outside, of the movable part.
- the contact switch is preferably a door contact switch, the door contact switch detecting a closed position of the door.
- Such contact switches are regularly arranged in the area of the mounting or suspension of the movable part or on the side opposite the mounting, on which the vehicle lock is regularly located. According to the invention, it is particularly advantageous if the contact switch is not accessible to a person, so that manipulation in this regard can at least be made more difficult or prevented.
- a contact switch according to the invention can be arranged, for example, in the area of the door mounting / door suspension and at least partially covered by parts of the body.
- a plurality of contact switches can particularly preferably be arranged at different points on the movable part, so that incorrect actuation or deliberate manipulative actuation is at least made more difficult.
- the first or the second signal source is a closing aid for the vehicle lock and / or a drive for the movable part.

- a drive according to the invention and / or a stand according to the invention regularly have a position sensor system which makes it possible to infer the position of the movable part.
- the second signal source can be a lock holder sensor.
- a lock holder sensor according to the invention detects whether the movable part is in the closed position, in particular in the locked position, and thus forms a reliable second position signal. It is particularly preferred if the lock holder sensor is arranged on the movable part or the vehicle in such a way that it is inaccessible from the outside for people or disruptive environmental influences. As a result, intentional or unintentional manipulation can be further reduced, as a result of which the reliability and thus the security can be further increased.
- the second signal source is a force sensor for detecting a sealing pressure of the movable part.
- the force sensor detects the pressure on the seal, in particular in the form of a door seal pressure, the pressure being generated by a closed state of the movable part.
- the seal can be arranged on the movable part or on the vehicle.
- the force sensor is arranged on and / or at least partially in the seal.
- the force sensor can be arranged on / in the seal only at certain points or over the entire circumference.
