Definitions
- the invention relates to a keyless access authorization system for a vehicle in which a control device in the vehicle with a portable transponder in the question-answer dialog checks and releases or blocks the authorization to unlock and lock the vehicle doors, at least one in the exterior mirror on the driver's side Antenna for sending and receiving the question
- Transponder is a portable authorization badge with identification identifier, which is known in various configurations, is inductively or via another wireless communication method coupled to the control unit in the vehicle and carries out the question-answer dialog.
- a keyless entry authorization system which is mainly used as an anti-theft security system, is known from DE 35 36 377 A1.
- the question-answer dialog can be started by pressing the door handle.
- the communication area between the portable transponder and the antenna of the control unit housed in the vehicle is limited, since, depending on the transmission method chosen, the portable transponder for the question-answer dialog is as close as possible to the antenna in the exterior mirror on the driver's side of the Vehicle must be brought in order to achieve a safe operation.
- the operational safety and thus the achievable range of communication between transponder and vehicle is determined by the spread of the field lines in inductive communication. This spread can be changed considerably by larger, magnetically conductive objects.
- Such objects are mainly the body of both their own vehicles and those parked in close proximity.
- the communication range is therefore dependent on the alignment of the antennas of the vehicle and the transponder with respect to one another, ie the transponder is to be aligned differently depending on the location.
- One-handed operation of the door handle and a transponder is therefore hardly possible.
- the low transmission power of the transponder makes it difficult to reliably receive its response through an antenna in the exterior mirror if the transponder transmits in the area of the handle of a rear door.
- This object is achieved according to the invention in that at least on the driver's side in the area of a rear side window or the rear vehicle door there is a further antenna which is also connected to the common control device and for sending the query signal from the control device and / or for receiving of the response signal of the portable transponder can be used, the two antennas generating a two-dimensional electromagnetic field due to their arrangement in the transmission mode.
- the transponder Because of this two-dimensional field spread, the transponder is always in a favorable position at least with respect to one of the two antennas. A position independence of the transponder in the electromagnetic field of the two antennas is thus achieved. With the additional antenna in the area of the rear side window or the rear vehicle door, the communication area is extended so that it extends over the entire side of the vehicle, the desired position independence of the transponder for secure data exchange being ensured in the overlapping area of the two antennas.
- the two antennas can cooperate with the control device in such a way that the control device uses the antenna in the exterior mirror Transmits question signal and via the additional antenna in the area of the rear side window or the rear vehicle door the response signal of the portable
- the further antenna can be attached to the pane of a rear side window. But it can also be arranged on the inside of the rear vehicle door or e.g. be built into the interior paneling of the rear vehicle door, provided communication with the transponder is guaranteed.
- the handle of the doors are each connected to the control unit via two separate control lines, which can be acted upon with a request signal depending on the desired unlocking or locking process.
- control can take place in such a way that the control unit only controls the door locks on the vehicle side for unlocking or locking, from which the initiation of the question-answer dialog was based, or that the control unit is independent of the location of the initiation of the question-answer dialog basically controls all door locks of the vehicle for unlocking or locking.
- the communication area between the portable transponder and the antenna of the control unit housed in the vehicle can thereby be considerable be expanded that two antennas are also arranged on the passenger side of the vehicle, which are connected to the common control unit.
- the system can be designed in such a way that the vehicle sides with their two antennas and the associated door locks form separate subsystems that work together or independently of one another in the question-answer dialog.
- the control unit can control the door locks in such a way that only the door lock or door locks on the vehicle side are actuated, from the handle of which the initiation of the question-answer dialog is based, or that all door locks are controlled centrally.
- At least the two antennas on the driver side are also used in a start / driving authorization system.
- Fig. 1 shows an access system with two antennas on the driver side with the initiation of the question-answer dialog only via the handling of
- Fig. 2 shows an access system with two antennas on each side of the vehicle with initiation of the question-answer dialog from both sides of the vehicle.
- a control device 10 is housed in the vehicle, which in a known manner in the question-answer dialog with a portable device (not shown)
- Transponder can communicate.
- any electronic identity card is included with the transponder, which can receive a question signal and send an answer signal.
- 14.1 and 14.2 denote the door locks of the two vehicle doors, the handling of which is connected to the common control unit 10 via two control lines 15a and 15b. With the respectively required actuation process of the handle of the door locks 14.1 and 14.2, an unlocking or a locking request can be indicated to the control unit 10 via the control lines 1 5a and 1 5b.
- control unit 10 outputs the query signal to the antenna control lines 1 6, which is emitted via the antenna 1 2 in the exterior mirror 1 1 and the further antenna 1 3.
- the further antenna 1 3 can be installed on the window of a rear side window or on the outside of the rear vehicle door or in the interior lining thereof. If authorization of the response signal of the transponder is recognized, the control unit 10 issues the command to unlock or lock the door locks 14.1 and / or 14.2.
- the passenger side BFS of the vehicle can also be provided with two antennas 19 and 20, which are arranged and operated in accordance with antennas 12 and 13 of the driver side FS, as shown in FIG. 2.
- the antenna pairs 12 and 13 or 19 and 20 can form a uniform access authorization system or separate subsystems with the associated door locks 14.1 and 14.2 or 14.3 and 14.4 and their handling, which cooperate with the common control device 10.
- all handles of the door locks 14.1 to 14.4 control the initiation of the question-answer dialog and all door locks 14.1 to 14.4 are included in the unlocking and locking process.
- All antennas 12, 13, 19 and 20 can be used to send the query signal and to receive the response signal; in a special embodiment, antennas 12 and 19 can also only be used to send the query signal and antennas 13 and 20 can only receive the response signal from common control unit 10 can be controlled.
- the transponder can still receive the question signal in a position in the area of the rear vehicle door due to the large transmission power of the antennas 12 and 19 in the rear view mirror 11 and 18, but the lower power of the response signal emitted by the transponder is not sufficient. / To control reception antennas in the rear view mirror again. However, the power delivered by the transponder is sufficient for the response signal to be received by the receiving antenna in the area of the rear side window or the rear vehicle door.
- the subsystems can work independently of one another only for their assigned vehicle side FS or BFS.
- the communication area is extended to both sides of the vehicle and extends largely over the entire sides of the vehicle.
- a further embodiment provides that the unlocking and locking is limited only to the door lock, on the handle of which the question-answer dialog was initiated and the identification was successful.
