Description

Technical Field

[0001] The present invention relates to a method for operating a vehicle locking system and a vehicle. Background Technology

[0002] The vehicle locking system discussed has an electric actuator for providing motorized locking functionality of the vehicle, wherein the vehicle's central battery supplies power to the electric actuator during normal operation. This type of vehicle locking system can be applied to the vehicle's adjustable elements in all types of motorized locking functions. Particularly belonging to this category are vehicle locking systems with vehicle locks. Adjustable elements are particularly understood to be doors, such as side doors, rear doors, tailgates, trunk lids, hoods, or similar types, which can in principle be constructed as revolving or sliding doors.

[0003] For example, a vehicle locking system can operate using a vehicle lock having a locking pin and a pawl as locking elements. The locking pin can be brought to a locked position, in which it is continuously engaged with a locking portion, such as a keyhole or the like, and in this locked position, the locking pin is secured by the pawl. For example, a motorized locking function can involve the electric opening of the vehicle lock. In this case, the vehicle lock is equipped with an electric actuator that retracts the pawl, allowing the locking pin to open the locking portion. Similarly, a motorized locking function can involve not only changing the locked state of the vehicle lock, such as releasing or locking, but also pulling up the vehicle lock. Furthermore, the locking function may involve motorized adjustments, such as motorized adjustments to the opening or closing movement of an adjusting element.

[0004] To ensure the safety of the voltage supply to this type of vehicle locking system, mechanical redundancy can be incorporated. For example, in addition to the motorized retraction of the pawl, a mechanical operating line (Betaetigungsstrang) is provided to the pawl, allowing manual retraction via the inside door handle. However, due to the high complexity of this type of vehicle locking system, electric vehicle locks without mechanical redundancy have also been developed.

[0005] The challenge of this vehicle locking system is to ensure that the locking function is still possible even in the event of a power supply interruption, such as when the vehicle's central battery fails.

[0006] The known method from which this invention originates (DE 10 2017 125 719 A1) relates to an auxiliary energy delivery device for a vehicle locking system, which is, for example, arranged behind a lappe for the lock cylinder of the vehicle locking system. The auxiliary energy delivery device is externally accessible and is used to deliver electrical energy to the vehicle locking system, such that in emergency operation, an external energy source can be connected to the auxiliary energy delivery device to operate the vehicle locking system and trigger an electric unlocking process. Summary of the Invention

[0007] The problem upon which this invention is based is to construct and extend known methods for operating motor vehicle locking systems, thereby further improving the security of motor vehicle locking systems.

[0008] The above problems are solved by the embodiments provided by the present invention.

[0009] The primary consideration is that, in the case of an externally accessible auxiliary energy delivery device, it may be impermissible to connect to the vehicle's electronic systems, which could achieve electrical connection with the central battery and / or the vehicle's locking system. There is a risk of manipulating the vehicle's electronic systems, which could even damage the vehicle's electrical system. The consideration is based on the following: the auxiliary energy delivery device is located in the vehicle's locking system, which has a locking element configured to occupy an open position and a closed position, wherein the locking element blocks access to the auxiliary energy delivery device in the closed position and allows access to the auxiliary energy delivery device in the open position.

[0010] In addition, the central battery is monitored by the control unit to check whether it meets the emergency operation standards.

[0011] In detail, it is suggested that the locking element is locked in the closed position by means of the locking unit in the locked state, and in order to meet the emergency operation standards, the control unit operates the locking unit to unlock the locking element from the locked state.

[0012] Therefore, it is achieved that, during normal operation, the locking element can remain in the locked state, and thus access to the auxiliary energy delivery device is impossible. In the locked state, operation of the vehicle's electronic devices via the auxiliary energy delivery device is prevented. However, in the event of an emergency operation requiring access to the auxiliary energy delivery device, the locking element is unlocked, and access to the auxiliary energy delivery device is permitted.

[0013] In a preferred embodiment, an energy storage device is provided for the locking unit, which is unlocked using energy stored in the energy storage device. This ensures unlocking is guaranteed independently of power supply from a central battery. Preferably, the energy storage device is configured as a rechargeable energy storage device and is charged by a control unit during normal operation.

[0014] Since the locking elements may be unlocked immediately upon entering emergency operation, only a short hold time and low capacity of the energy storage device are required according to the proposed method. Therefore, an energy storage device having a capacitor, preferably a ceramic capacitor, and / or a double-layer capacitor can be particularly advantageously employed according to a construction scheme.

[0015] In a preferred configuration, security against unauthorized access to the vehicle's electronic devices is further enhanced by electrically isolating the auxiliary energy delivery device from the central battery and the vehicle locking system in a locked state. To ensure compliance with emergency operation standards, a control unit is configured to electrically connect the auxiliary energy delivery device to the central battery and / or the vehicle locking system.

[0016] A preferred embodiment of a locking element is provided, wherein the locking element may further be configured as part of a cover, door, door operating element, and / or external element of a motor vehicle.

[0017] In a particularly preferred configuration, the locking element is configured to occupy a pre-locked position (Vorraststellung) as the open position. In emergency operation, the locking element can be moved to the pre-locked position, blocking any transition from the pre-locked position to a further open position. In this particularly practical variant, for example in emergency operation, the door can be brought to the pre-locked position to allow access to the auxiliary energy delivery device, where, as a safety measure, full opening of the door is prevented.

[0018] After unlocking, the locking element can remain in the closed position, or be motorized from the closed position to the pre-locked position or the open position by means of the locking unit.

[0019] A preferred construction scheme for emergency operation criteria is presented, in particular to prevent misidentification based on the pre-defined time change process of the central battery's state variables.

[0020] In another particularly suitable configuration, the locking unit has a bistable locking element that is adjusted from a first stable position to a second stable position by an actuator for unlocking.

[0021] In one configuration, the auxiliary energy delivery device is configured to deliver electrical energy from an external energy source. Alternatively or additionally, the auxiliary energy delivery device may be configured to generate electrical energy from the movement of the auxiliary energy delivery device by an operator, thereby eliminating the need for an external energy source.

[0022] As mentioned at the beginning, in the preferred embodiment, the vehicle locking system has a vehicle lock with an adjustment element for the vehicle. Preferably, an electric actuator is provided for motorized retraction of the pawl, wherein the vehicle lock can also be electrically unlocked during emergency operation of the invention.

[0023] Similarly, in a further preferred embodiment, an electric actuator may be provided for changing the locking state of the vehicle lock within the scope of the locking function, and / or for engaging the vehicle lock within the scope of the locking function.

[0024] A preferred construction scheme for a motorized locking function that can also be implemented in emergency operation within the scope of the proposed method is derived by setting an adjustment element for motorized adjustment of the motor vehicle in an electric actuator configuration.

[0025] According to another teaching, which takes on independent significance, protection is required for a motor vehicle used to perform the method according to the recommendation. Regarding this other teaching, reference may be made to all implementation schemes for the method according to the recommendation.

[0026] The invention will now be described in more detail with reference to one embodiment. Detailed Implementation

[0027] The present invention relates to a method for operating a motor vehicle locking system, wherein the motor vehicle locking system has an electric actuator for providing motorization locking functionality of the motor vehicle, which is further described below.

[0028] Preferably, the vehicle locking system is a vehicle locking system without mechanical redundancy, wherein the locking function can be provided solely via an electric actuator.

[0029] The central battery of a motor vehicle supplies electrical energy to the electric drive system during normal operation. The central battery is preferably a battery that also provides the electrical energy required to start the motor vehicle and / or for the electric drive system of the motor vehicle.

[0030] An auxiliary energy delivery device is provided for delivering electrical energy to the central battery. In this invention, the auxiliary energy delivery device is connected to the central battery via electrical lines that can be closed via a switch. Alternatively or additionally, the auxiliary energy delivery device can be used to deliver electrical energy to the vehicle locking system. Typically, even in the event of a central battery failure, the auxiliary energy delivery device can enable the operation of the vehicle locking system.

[0031] An auxiliary energy delivery device is arranged in a locking device of a motor vehicle with a locking element, wherein the locking element is configured to occupy a closed position and an open position. In this invention, the locking element is pivotally arranged on the vehicle body, wherein, for example, a locking element that can be longitudinally offset is also conceivable.

[0032] The locking element blocks access to the auxiliary energy delivery device in the closed position and allows access in the open position. Blocking access in this case means that, due to the spatial layout of the auxiliary energy delivery device, it is impossible for the operator to use the device without moving the locking element. In this invention, the locking device constructs a space accessible only through an outwardly oriented opening. In the closed position, the locking element substantially completely covers this opening, such that access to the auxiliary energy delivery device is only possible when the locking element is opened from the closed position.

[0033] The central battery is monitored by a control unit to check whether emergency operation criteria are met. The emergency operation criteria, further elaborated below, typically indicate that the central battery is in a state where power supply to the vehicle locking system is no longer reliably guaranteed, and therefore, access to an auxiliary energy delivery device is necessary. The control unit may be a separate control unit assigned to the auxiliary energy delivery device. The control unit may also be assigned to the central vehicle control unit of this invention.

[0034] The important thing now is that the locking element is locked in the closed position by means of the locking unit in the locked state.

[0035] In the locked state, the locking element is fixed by the locking unit, thus preventing the opening of the locking element and the access to the auxiliary energy transmission device.

[0036] When the entire vehicle locking system is in a locked state ("locked") and / or a locked state ("anti-theft"), then preferably at least the locking element and the locking unit are in a locked state. In another configuration, the locking element and the locking unit are always in a locked state during normal operation, thus achieving a particularly high level of security against unauthorized access to the auxiliary energy delivery device.

[0037] Furthermore, and importantly, given that emergency operation standards are met, the locking unit is operated by the control unit to unlock the locking element from the locked state.

[0038] With unlocking, the locking element occupies the unlocked state. Except for unavoidable delays, such as those caused by control technology, unlocking is preferably performed directly at the moment when the emergency operation criteria are met, thereby ensuring that the locking element is unlocked upon entering emergency operation.

[0039] In another implementation, the locking unit is activated only if at least one other criterion (e.g., an authentication criterion) is met, given that the emergency operation criteria are satisfied. When verifying the authentication criterion, the control unit can, for example, query the presence of an authentication unit (e.g., for a keyless access transmitter). However, in another implementation, the emergency operation criteria are a sufficient condition for activating the locking unit to unlock. This further simplifies the method and reduces energy consumption during emergency operation.

[0040] It is conceivable that the locking unit is also powered by the central battery for unlocking, with the emergency operation criterion chosen such that sufficient energy is retained in the central battery even during the transition to emergency operation to facilitate unlocking. However, according to a particularly preferred configuration, an energy storage device is provided for the locking unit. The locking unit unlocks using the energy stored in the energy storage device. Similarly, the control unit can be powered by the energy storage device.

[0041] Preferably, the energy storage device is constructed as a rechargeable energy storage device and is charged during normal operation by means of a control unit (in this invention, via energy stored in a central battery). The rechargeable energy storage device may have at least one electrochemical primary single cell and / or secondary single cell. In this invention, and preferably, the energy storage device has capacitors, preferably ceramic capacitors and / or double-layer capacitors. In the double-layer capacitor, energy is stored in an electrochemical double layer, which is also known as a "Helmholtz layer" ("Lexikon - Aktuelle Fachbegriffe aus Informatikund Telekommunikation", 9th edition, 2007, VDF High School Press AG, p. 86). Such a double-layer capacitor is also referred to as a "supercapacitor", "Ultracap", or something similar. The double-layer capacitor can provide high power density for unlocking and locking elements.

[0042] According to another design, the auxiliary energy delivery device is electrically disconnected from the central battery and the vehicle locking system in the locked state. The invention includes the previously mentioned switch, which is open in the locked state and controlled by a control unit. The switch can be implemented as a semiconductor device. However, in principle, other designs are conceivable: electrically disconnecting the auxiliary energy delivery device from the central battery and the vehicle locking system in the locked state, for example, through circuitry separation. In this invention, to meet emergency operation criteria, the auxiliary energy delivery device is electrically connected to the central battery via a control unit, where the previously mentioned electrical connection to the vehicle locking system is also conceivable. The switch can be closed by means of the control unit.

[0043] The locking element is preferably constructed as a cover. In one embodiment, the locking element is constructed as a fuel tank cover of a motor vehicle, which also provides access to the fuel tank cover in the open position. Similarly, the locking element can be implemented as a tailgate. It is further conceivable to construct the locking element as a cover specific to an auxiliary energy delivery device, especially a cover without dual functions.

[0044] According to one construction scheme, the locking element can be constructed as a door of a motor vehicle. In particular, this case involves a door to which the aforementioned motor vehicle locking system is also assigned.

[0045] According to another construction scheme, the locking element can be configured as a door operating element, such as a door handle and / or a door handle recess. For example, an auxiliary energy delivery device is arranged on the contour of the door handle and / or door handle recess, wherein the auxiliary energy delivery device can only be accessed when the door handle is pulled, which in this case corresponds to the open position of the locking element.

[0046] Furthermore, the locking element can be constructed as part of the vehicle's external components. An example of this is a vehicle's exterior rearview mirror, which can be moved from a folded (closed) position to an unfolded (open) position, wherein access to the auxiliary energy delivery device is only enabled in the unfolded position. In this invention, other components of the vehicle body shell are also understood as external vehicle components, such as trim strips, partitions, covers, or the like.

[0047] According to a particularly preferred configuration, the locking element is configured to occupy a pre-locked position as an open position, wherein access to the auxiliary energy delivery device is enabled in the pre-locked position. In particular, the locking element is constructed via a door assigned to the vehicle locking system. In this case, the vehicle locking system may have a locking unit, wherein the closed position of the locking element corresponds to the main lock position (Hauptraststellung) of the door.

[0048] By unlocking, the locking element can be moved from the closed position to the pre-locked position using the locking unit. In this case, for example, the locking unit secures the door in the main lock position in the locked state. Given that the emergency operation criteria are met, the main lock position is released, and the door can be moved to the pre-locked position, wherein an auxiliary energy delivery device is arranged, for example, in the door gap that appears in the pre-locked position.

[0049] Preferably, particularly the vehicle locking system, blocks the transition of the locking element from the pre-locked position to a further open position. In the previously described embodiments, the door may only be brought to the pre-locked position, but the door cannot be further opened from the pre-locked position. Thus, entry into the vehicle interior is only possible when an auxiliary energy delivery device is used to deliver energy and the motorized locking function is used, for example, with authentication.

[0050] In another configuration, the locking element remains in the closed position after unlocking. In this case, the operator can manually move the locking element to the open position to gain access to the auxiliary energy delivery device. Alternatively, for improved comfort, the locking element can be moved from the closed to the open position via a locking unit, for example, through a motorized adjustment.

[0051] Preferably, the emergency operation criterion is defined at least in part by not exceeding the preset limits of the central battery's state variables. The state variables are, in particular, the central battery voltage or related variables. The preset limits may correspond to the minimum voltage of the central battery.

[0052] More preferably, the emergency operation criteria are defined at least in part by ensuring that the state variables of the central battery do not exceed a predetermined limit during a pre-given minimum time period. This means that the limit preset must be continuously observed during the minimum time period for the relevant sub-criteria to be considered satisfied. In this configuration, erroneous triggering of emergency operation due to brief disturbance pulses in the monitored state variables can be eliminated with high reliability.

[0053] More preferably, the emergency operation criteria are defined at least in part by the following manner: state variables conform to a pre-defined time-varying process. The pre-defined time-varying process may, for example, represent the typical discharge process of the central battery.

[0054] In another configuration, the control unit is configured for an idle mode, which is preferably present during normal operation. Given the satisfaction of emergency operation criteria, the control unit can be switched from the idle mode to the active mode. For example, in this case, the switch to the active mode can be automatically initiated, making monitoring of the central battery's status less necessary.

[0055] As already described, the locking unit can be part of a vehicle locking system. However, the locking unit can also be constructed independently of the vehicle locking system. In a preferred embodiment, the locking unit has a bistable locking element that is adjusted from a first stable position to a second stable position by an actuator for unlocking. The first stable position corresponds to the locked state in this case, and the second stable position corresponds to the unlocked state. Advantageously, the actuator can be adapted accordingly to conditions during emergency operation.

[0056] In this invention, and preferably, the auxiliary energy delivery device is configured to deliver electrical energy from an external energy source. For this purpose, the auxiliary energy delivery device can be implemented as a socket, a terminal block, or the like. In particular, the auxiliary energy delivery device is configured for connection to a mobile energy storage device, for example, for connection to a mobile energy storage device via a USB plug. Similarly, the auxiliary energy delivery device can be configured for connection to a startup auxiliary cable.

[0057] However, alternatively or additionally, an auxiliary energy delivery device may be configured to generate electrical energy from movement of the auxiliary energy delivery device by an operator. In this case, the auxiliary energy delivery device has a generator that converts kinetic energy into electrical energy. For example, the auxiliary energy delivery device may be equipped with a motion element configured for movement by an operator. Similarly, movement of a locking element may be used to generate energy.

[0058] The motorized locking function is particularly understood to mean that the adjusting elements of the motor vehicle are adjusted, directly or indirectly, by movement generated by an electric actuator, such as being opened or closed, and / or the adjusting elements being locked or released. One embodiment of a motor vehicle locking system has a motor vehicle lock for a side door. The motor vehicle lock, belonging to the motor vehicle locking system, is equipped with a locking pin and a pawl, the locking pin being pivotable about a pin axis for continuous engagement with a locking portion, and the pawl being assigned to the locking pin and pivotable about a pawl axis. The locking portion can be a latch, keyhole, or the like. For example, the motor vehicle lock is located on the side door, while the locking portion is fixedly located on the motor vehicle relative to the vehicle body.

[0059] The pawl can be brought to an inclined position, where it holds the locking pin in the locked position by means of the pawl spikes. Furthermore, in a preferred embodiment, the pawl can be retracted motorically by means of an electric actuator. For this purpose, the drive motor of the electric actuator is preferably connected to the pawl via a transmission cable. In principle, the pawl can also be part of a pawl system consisting of two or more sequentially arranged pawls assigned to the locking pin.

[0060] The motorized retraction of the pawl is triggered, for example, by operation of a door handle. For this purpose, the door handle is equipped with a sensor or similar device that detects the operation of the door handle and forwards the detection result (Erfassung) via a control connection to a locking system control unit, which triggers operation of the electric actuator. The locking system control unit may, in particular, have a control unit as already described.

[0061] Motor vehicles may have multiple vehicle locking systems, such as for multiple doors, where possible configurations are described in the implementation scheme at the beginning.

[0062] According to another configuration, the electric actuator is configured to change the locking state of the vehicle lock within the scope of the locking function. For example, the locking mechanism of the vehicle lock can be brought to mechanical locking states "Release" (UL), "Lock" (CL), and "Impact" (DL) in a manner known per se, wherein the pawl can retract from the outside and inside in the locked state UL, from the outside but from the inside in the locked state CL, and from neither the outside nor the inside in the locked state DL. Preferably, the electric actuator is configured to cause a transition to the locked state UL within the scope of the locking function.

[0063] According to another preferred embodiment, the electric actuator is configured to engage the vehicle lock within the range of the locking function, wherein the electric actuator preferably acts on the lock pin and / or the locking portion. Engaging preferably causes a motorized adjustment of the adjusting element from the open position and / or from the pre-locked position to the master lock position. This engagement function reduces the load on the operator's final adjustment section, which typically has to withstand high door sealing pressure.

[0064] In addition to or replacing the locking function described for motor vehicle locks, motor vehicle locking systems may also have an actuation device, which is preferably used for motorized adjustment (especially opening and / or closing) adjustment elements. Another example of a locking function is: motorized adjustment elements such as levers, door handles, and motorized adjustment elements for the interior and exterior spaces of the motor vehicle, such as ventilation elements, interior mirrors, exterior mirrors, lighting equipment, or similar components.

[0065] According to one construction scheme, the locking element can correspond to an adjustment element assigned to it by the vehicle locking system.

[0066] Based on another teaching that has been independently derived, protection is required for the aforementioned motor vehicle itself, which is designed to perform the methods according to the recommendations. Reference is permitted to all the above implementation schemes for the methods according to the recommendations, and especially to the construction scheme of the motor vehicle used in this context.
