Description

The invention relates to a system for a safety device of a motor vehicle, with a handle which has a switching element and a lock which can be brought into a locked state and an unlocked state at least.

From the DE 10 2004 021 505 B3 describes a system for a safety device of a motor vehicle, which has a lock that normally holds a door of the motor vehicle in the closed position. The lock can optionally be in one of two operating positions, namely in a locked state and an unlocked state. In addition, a handle is described as a door handle that can be operated by a user so that the handle on the door can be pivoted. The handle is pivoted at one end to the door. The axis of the pivot bearing extends vertically, which is why the handle can also be called a pull handle. The other end of the handle has an extension with a hook end that is mechanically connected to the lock. However, it has been shown that efforts are being made to design the system for operating the safety device of a motor vehicle and the handle as such to be simpler and more compact, as a result of which the assembly effort and manufacturing outlay can be further reduced.

Furthermore, an actuating device for a motor vehicle door is in the DE 10 2004 045 152 A1 described.

The invention has for its object to provide a system for a safety device of a motor vehicle, which avoids the disadvantages mentioned, in particular an assembly-friendly system or an assembly-friendly handle is provided, at the same time a reliable functioning is guaranteed.

To solve this problem, a system with all the features of claim 1 is proposed. Advantageous embodiments of the system according to the invention are listed in the dependent claims.

According to the invention, it is provided that the system is designed with an immovable handle that has a switching element. The system also has a lock that can be brought into at least a locked state and an unlocked state. In addition, a verification unit is integrated in the system, which carries out an identification check with a portable identification transmitter when the handle is activated, the lock being electrically actuable by the switching element when the identification is positive, as a result of which the state of the lock can be changed. If the identification is negative, the lock is electrically decoupled from the switching element in such a way that the lock does not change state when the switching element is actuated. The invention includes that an electrical decoupling can also be present if the switching element sends a switching signal to the lock, but a control unit of the system has not yet transmitted a release signal to the lock to carry out a change of state. An essential part of the invention is that the handle is rigidly and immovably arranged or can be arranged on the motor vehicle. The handle has a switching element that can be actuated by the user to trigger an action, in particular to bring the lock, which is arranged at a distance from the handle or from the switching element, from its locked state into the unlocked state and vice versa. The handle is preferably immovable on the motor vehicle door. The activation of the handle according to the invention takes place by approaching the handle or touching the handle in order to start an identification check. The identification check is carried out with the identification transmitter that the user carries with him and the security device of the motor vehicle. The security device can be designed as a keyless access and / or driving authorization control system. An immobilizer can also be integrated in the safety device. During the identification check, a query is made as to whether the user is authorized to activate the safety device of the motor vehicle, which means to what extent the user is authorized to bring the lock between the locked state and the unlocked state, for example. For example, codes can be exchanged between the identification transmitter and the motor vehicle as part of the identification check. If there is a positive identification, the user can actuate the switching element that is electrically connected to the lock. The lock is switched electrically from its locked state to the unlocked state and vice versa. The lock advantageously has an electrical input. The trigger for such an electrical reversal of the lock can be the activation of the handle and / or the actuation of the switching element. The checking unit can be integrated in the safety device. It is also conceivable that the checking unit is contained in the rigid handle. The checking unit can be part of the vehicle control, which is arranged on the motor vehicle side. If the identification is negative, the switching element can be actuated by the user, but the lock does not change from the locked state to the unlocked state or vice versa.

According to the invention it can be provided that the switching element comprises an electromechanical button and / or changeover switch. The switching element is in signal connection with the lock. By actuating the electromechanical button, the lock receives a pulse or a signal, which means that the lock status can be reversed electrically. The switching element can be connected to the lock via a cable element. It is also conceivable that the castle and communicate with the switching element via radio. Of course, it can be provided that the security device and / or the checking unit are electronically connected both to the switching element and to the lock.

In a measure improving the invention, it is conceivable that activation of the handle can be triggered by actuating the switching element. In this embodiment according to the invention, actuation of the switching element results in both an identification check and a change in the state of the lock, namely when there is a positive identification. The identification check can be carried out simultaneously with the mechanical actuation of the switching element. For example, it can be provided that when the electromechanical push button is actuated, a further switch is additionally actuated which triggers the identification check. It can also be provided that the identification check is first connected upstream, before a corresponding activation of the lock is permitted or not when the switching element is actuated.

It is also conceivable according to the invention that a first sensor element is provided which can be activated by a user, as a result of which the lock can be brought from the unlocked state into the locked state. This first sensor element thus serves to bring the lock, which is in the unlocked state, into the locked state. The door of the motor vehicle is locked in the locked state. In the unlocked state, the door of the motor vehicle is unlocked.

The invention does not include that the first sensor element is integrated in the handle. Thus, according to the invention, the handle does not form a common structural unit with the first sensor element. According to the invention, it is provided that the first sensor element can be attached to the motor vehicle. This means that the first sensor element is arranged at a distance from the handle on the motor vehicle and / or on the door of the motor vehicle. For example, it is conceivable that the first sensor element is integrated in the safety device of the motor vehicle. For example, the first sensor element can also be integrated in the checking unit which is responsible for the identification check.

In addition, according to the invention, the system can be designed such that a second sensor element is integrated in the handle, which can be activated by a user, as a result of which the identification check can be triggered. For example, the first sensor element and / or the second sensor element can be a proximity sensor and / or a touch sensor, in particular the first sensor element or the second sensor element being a capacitive sensor. The first and / or the second sensor element can also be designed as piezo sensors. The first and the second sensor element are advantageously designed as metallic electrodes, which are connected to electronics that are located, for example, in the handle. In addition, the invention can include that the switching element and / or the first and / or the second sensor element are designed as force sensors, so that a corresponding action is triggered by touching the switching element and / or the housing of the handle in the vicinity of the sensor elements. For example, it is possible for the handle to have a metallized surface that serves as a force sensor.

In Figure 1 A motor vehicle 2 is shown which is equipped with a safety device 1. The security device 1 can also include an access and driving authorization control system which serves to ensure that only the authorized user can get into the motor vehicle 2, the motor vehicle 2 can start or the motor vehicle 2 can lock and unlock. The invention proposes a system 10, which among other things in the Figures 4 to 6 is shown schematically what will be discussed below. The system 10 comprises an immovable handle 20 which corresponds to a switching element 21 Figure 2 and Figure 3 having. The handle 20 is electronically connected to a lock 50, which can be brought into a locked state and an unlocked state at least. The motor vehicle door 8 is locked in the locked state. In the unlocked state, the door 8 can be opened by the user by actuating the switching element 21. A keyless access control system is integrated in the system 10 according to the invention, which works with an identification transmitter 4, which in Figure 1 is shown schematically. The user carries this identification transmitter 4 with him, an identification check being started when the handle 20 is activated. Communication takes place here between the identification transmitter 4 and the security device 1, a checking unit 3 checking to what extent the coded data transmitted by the identification transmitter 4 match the data on the motor vehicle side. If the identification is positive, the switching element 21 can be actuated, as a result of which the state of the lock 50 can be changed. This means that the lock 50 can be brought from its locked state into the unlocked state by actuating the switching element 21. According to Figure 3 the switching element 21 is connected to the lock 50 via a cable element 5. Instead of the cable element 5 it is it is also conceivable for the switching element 21 to communicate with the lock 50 by radio.

If the identification is negative, the lock 50 remains electrically decoupled from the switching element 21, so that when the switching element 21 is actuated, the lock 50 does not change state.

The checking unit 3 can be as in Figure 1 shown to be integrated in the safety device 1. The handle 20 itself can also be formed with the checking unit 3, which is not explicitly shown.

In Figure 2 the handle 20 is located in a door recess 9 of the motor vehicle 2. In addition to the switching element 21 accessible from the outside, the handle 20 has a lighting element 26 which serves as apron lighting for the motor vehicle door 8. A first sensor element 31 is provided adjacent to the handle 20, which will be discussed in the following.

In Figure 3 A possible handle 20 with a housing 23 is shown, which for a safety device 1 according to FIG Figure 1 can serve. The handle 20 has the switching element 21 in order to bring the lock 50 from its locked state into the unlocked state. In addition, a first sensor element 31 is provided on the housing 23, which can be activated by the user in order to bring the lock 50 back from the unlocked state into the locked state. The first sensor element 31 has an elongated extension. Alternative geometric shapes, configurations and positions of the first sensor element 31 are conceivable, which depends, among other things, on the geometry of the handle 20.

According to Figure 3 The handle 20 has a second sensor element 22 which can be activated by the user, whereby an identification check can be triggered. If the identification is positive, the lock 50 can be moved from its locked position into the unlocked position by activating the switching element 21. The second sensor element 22 is part of an activation element 24, which is in the switching element 21 is integrated. In the present exemplary embodiment, both sensor elements 22, 31 are designed as proximity sensors, capacitive sensors. It is also conceivable that at least one of the two sensor elements 22, 31 are designed as touch sensors. The handle 20 according to Figure 3 also has fastening elements 27 which are used to fasten the handle 20 to the motor vehicle door 8. Furthermore, the handle 20 is designed with a recessed grip 7 in order to facilitate access to the switching element 21 for the user and / or to be able to open the door 8 conveniently. In the present exemplary embodiment, the switching element 21 is designed as a toggle switch. The housing 23 of the handle 20 is designed as an injection molded part made of plastic.

In contrast to Figure 3 the first sensor element 31 is separate from the handle 20 in Figure 2 arranged on the motor vehicle 2. This means that the handle 20 must be activated by the user in order to unlock the lock 50, the first sensor element 31 spaced apart from the handle 20 being activated by the user in order to lock the lock 50.

According to Figure 4 a possible electronics or a possible electronic circuit is shown, which according to the handle Figure 3 can be obtained. Here, the handle 20 has a housing 23 in which the first sensor element 31 and the second sensor element 22 are arranged. The first sensor element 31 serves to sense an approach of the user or a touch of the user, as a result of which the lock 50 can subsequently be brought from the unlocked state into the locked state. The second sensor element 22, on the other hand, serves to sense an approach of the user or a touch of the user, which triggers an identification check. Both sensor elements 22, 31 are connected to common electronics 15. It can also be provided that each sensor element 22, 31 has separate electronics. In addition, the handle 20 according to Figure 4 a mechanical switching element 21, which is electronically connected to the lock 30. Alternatively and / or additionally, the system 10 can have a control device, which is not explicitly shown, and which can be brought into a signal connection with the lock 30. Only when the control device has sent a release signal to the lock 30 and the switching element 21 has sent a corresponding signal to the lock 30 can a change of state of the lock 50 be triggered. The embodiment is also without a control unit conceivable, in this case a change of state of the lock 50 already takes place when the switching element 21 has sent a signal to the lock 30.

Only when there is a positive identification can the lock 30 be activated or activated by actuating the switching element 21 in order to change the state, in particular to bring it from a locked state to an unlocked state. According to Figure 4 an identification check can also be triggered when the first sensor element 31 is activated by the user.

In Figure 5 A system according to the invention is shown with a handle 20, the handle 20 having in its housing 23 the second sensor element 22, which is connected to the electronics 25. In addition, the handle 20 has the mechanical switching element 21, with which the lock 30 can be brought from its unlocked state into the locked state. Spaced from the handle 20, the first sensor element 31 is arranged on the motor vehicle, which has the same mode of operation as in FIG Figure 4 has already been described. This means that the lock 30 can be brought from the unlocked state into the locked state by approaching or by applying force to the first sensor element 31. It is conceivable here that an identification check is carried out upstream or that an identification check takes place simultaneously. The lock is only brought from the unlocked state into the locked state if the identification is positive. The first sensor element 31 has its own electronics 35. The first sensor element 31 with its electronics 35 represents an independent module, which can be attached to the motor vehicle, for example, as an insert, in particular can be clipped on. Later assembly and disassembly of this module is also conceivable. The trigger for the identification check can take place, for example, via the second sensor element 22, which can sense an approach of the user to the first sensor element 31. For example, the sensing area of the first sensor element 31 and the second sensor element 22 can be of different sizes. Of course, it can also be provided that the first sensor element 31 triggers the identification check and at the same time a positive identification lock 50 switches from the unlocked state to the locked state.

According to Figure 6 A further variant of the system 10 according to the invention for a safety device 1 of the motor vehicle 2 is shown. Here, the system as in Figure 5 shown a handle 20, which comprises a housing 23 in which a switching element 21 is located. As in the embodiment variants, the switching element 21 also serves Figure 4 and Figure 5 for switching the lock 50 from a locked state to an unlocked state. A major difference in Figure 6 is, however, that the handle 21 has no second sensor element. An additional switch 28 is provided within the handle 20 and is operated simultaneously when the switch 21 is actuated by the user, whereby an identification check is started. As in Figure 5 Already described, the system 10 has a separate first sensor element 31 with its own electronics 35, which is arranged at a distance from the handle 20 on the motor vehicle 2. The user can use this first sensor element 31 to bring the lock 30 out of the unlocked state into the locked state. Here, too, an identification check can be carried out beforehand or simultaneously with the identification transmitter 4, which the user carries with him. The switch 21 and the switch 28 can also be combined in one component, which is not explicitly shown.

In Figure 7 An example of an arrangement of the first sensor element 31 on the motor vehicle 2 is shown, the first sensor element 31 having a metallic electrode which is connected to the electronics 35. The first sensor element 31 is inserted with the electronics 35 in a housing 33, a plug being located in the lower region of the housing, as a result of which an electrical connection to the safety device 1 and / or the checking unit 3 and / or to the lock 50 is shown Figure 1 is conceivable. In the illustrated embodiment according to Figure 7 the structural unit shown, including first sensor element 31, housing 33 and electronics 35, is clipped onto the outer door skin of motor vehicle 2. The first sensor element 31 is designed such that an approach or a touch or a certain application of force is recognized by the user in order to take a corresponding action on the Trigger lock 50. It is also conceivable as an alternative that a switching element, in particular an electromechanical button, is used instead of the first sensor element 31.

As in Figure 4 to Figure 6 is also shown, the immovable handle 20 has a lighting element 26, which can be used, for example, for apron lighting on the motor vehicle 2. According to the invention, the immovable handle according to all the exemplary embodiments shown ( Figure 1 to Figure 7 ) can also be designed without a lighting element. However, the lighting element 26 can be advantageous, in particular to illuminate the switching element 21, the first sensor element 31 and / or the second sensor element 22 for the user in the dark. In addition, according to Figure 2 add that the activation element 24 can be integrated in the first sensor element 31 or in the second sensor element 22. The activation element 24 represents a defined area on which the user can actively start an identification check with the portable identification transmitter 4, regardless of whether the lock is to be brought from the unlocked state into the locked state or from the locked state to the unlocked state.

According to Figures 1,2 . 5-7 For example, an immovable handle 20 can be provided for a safety device 1 of a motor vehicle 2, with a housing 23 which has at least one switching element 21 which can be activated by a user in order to electronically activate a lock 50, and an activation element 24 which is arranged on the housing 23 and which can be activated by the user in order to carry out an identification check with a portable identification transmitter 4. The identification check is started via the activation element 24. After a positive identification, the lock 50 can be actuated electrically by actuating the switching element 21. Here, the lock 50 can be brought between a locked state and an unlocked state. The motor vehicle door 8 or motor vehicle 2 is locked in the locked state. In the unlocked state, the motor vehicle door 8 or motor vehicle 2 is unlocked. The lock 50 is addressed electronically via the switching element 21, so that there is no mechanical connection between the switching element 21 and the lock 50 according to the invention.

For example, the switching element 21 and the lock 50 can be electronically connected to one another via a cable. Communication between the switching element 21 and the lock 50 can also take place via radio. The handle 20 is rigid and immovable on the motor vehicle door 8. Advantageously, the motor vehicle door 8 in the adjacent area of the handle 20 has a recess and / or depression 7 in which the user can intervene in order to activate the switching element 21 on the one hand and To address the activation element 24 to others. In one possible embodiment, the activation element 24 can be integrated in the switching element 21. This means that an activation of the switching element 21 starts an identification check at the same time.

The handle 20, the switching element 21 can have a toggle switch. The mechanical toggle switch is a compact and reliable component.

The first sensor element 31 can be integrated in the activation element 24. In addition, it can be provided that a second sensor element 22 is arranged in the housing 23 and is integrated in the activation element 24.

Advantageously, the handle 20 has a lighting element 26 which can be used for apron lighting and / or for recessed grip lighting in the vicinity of the handle 20. The lighting can e.g. B. the switching element 21 and / or the activation element 24 of the rigid handle 20 make it better visible, in particular in the dark to enable the user to operate the handle 20 comfortably.

Activation of the handle 20 can advantageously be triggered by approaching the handle 20 and / or by touching the handle 20, in particular that activation of the handle 20 is triggered by actuating the switching element 21. It is also conceivable that a first sensor element 31 It is provided that detects an approach to the handle 20 and / or a touch of the handle 20 of a user, whereby the lock 50 is brought from the unlocked state into the locked state. Additionally and / or alternatively, a second sensor element 22 can be provided in the handle 20, which can be activated by a user, whereby the identification check starts.
