Definitions

  • the invention relates to an electronic locking system according to the preamble of claim 1.
  • locking systems which are used to secure access elements, such as doors and the like, in vehicles and other objects serve, generate locking control means locking and unlocking-related Locking control commands for the respective locking unit in Depends on whether they have associated detection sensors authorizing authentication element in a detection area determine the same.
  • the authentication element e.g. from a chip card, and the detection takes place typically through wireless communication between the closing control means and the authentication element, wherein the communication process also includes checking whether the authentication element individually valid for the object in question is.
  • the detection area is often the catchment area
  • Antenna unit defines the closing control means sense the presence of an authentication element and carry out the communication processes with it.
  • Such Systems are particularly used as vehicle locking systems and are also known as keyless go systems.
  • the closing control means generated closing control commands are release or lock commands, which release a locking or unlocking of the clamping unit or lock.
  • the vehicle doors can only operate when the door is unlocked or the boot lid can be opened.
  • the locking and Unlocking itself is preferably done by pressing one actuating element arranged on the vehicle, e.g. in shape an opening contact and / or a closing button on the outside the vehicle doors or the trunk lid, the beginning this operation simultaneously the communication process triggers for authentication check.
  • the user in itself locking function requested by this actuation is delayed the duration of the authentication process.
  • the patent DE 195 42 441 C2 discloses an antenna device for an anti-theft system of a motor vehicle with different antenna units, one at the front Vehicle doors and can be arranged on a boot lid and the outside part of the antenna capture area has a detection area defined within which an outside to the Vehicle brought up, acting as an authentication element Transponder recognized and can be queried for authorization.
  • a release signal is issued for example to unlock the doors or to disarm them an electronic immobilizer.
  • the invention is a technical problem of providing an electronic locking system of the type mentioned at the beginning, i.e. in the form of a keyless go system, based on that without noticeable Delay for the user reliably and / or flexibly a locking or unlocking of a locking unit desired by him enabled and with relatively few to be operated by the user Actuators get along.
  • the locking control means include an authentication element distance sensor system with which the removal of an authentication element from the one to be secured Object, such as a vehicle, can be determined if that Authentication element within the outer detection zone of a Detection sensor is located. It is understood that the distance sensors with the detection sensors to an authentication element detector unit can be summarized. Dependent on on the distance of the authentication element determined in this way The locking control means generate different objects Closing control commands.
  • the system design according to the invention allows the selection of different ones generated closing control commands depending on the position of the Authentication element within the respective outer detection zone.
  • the closing control commands can be assigned to the object Always generate in such a timely manner that there is no loss of comfort for the user through noticeable delay times result when performing desired locking functions.
  • the closing control means the closing control command automatically after recognizing an authorizing Generate authentication element and therefore not only on any control element actuation by the user there.
  • unlock-related closing control commands when the user approaches the object early before the time the user creates the Object reached and a control element for opening an access element, such as a door or the like.
  • the locking and unlocking-related closing control commands generated can Depending on the system design, mere enable and disable signals be a locking or otherwise triggering Release or block unlocking of the respective clamping unit, or they can use the lock and unlock control signals themselves form, which cause the clamping unit in question assumes their locked or unlocked state.
  • the locking system according to claim 1 is a division of respective outer detection zone of a detection sensor at least in a distance zone closer to and closer to the object provided between which the distance sensors distinguish can, i.e. it detects whether one is in the outer detection zone recognized authentication element in the object closer or lies in the distance zone away from the object.
  • the transition area between objects closer and closer to objects Distance zone forms a hysteresis area, i.e. the The closing control command generated is changed during the transition from the nearer object to the distant distance zone in a greater distance than vice versa when moving from the object distant to the distance zone closer to the object. This prevents the Generation of undefined locking and unlocking-related locking control commands before if there is an authoritative authentication element is in this border area.
  • This has the effect of closing control commands acting in the unlocking direction can only be generated when the user is familiar with the Authentication element is already relatively close to the object, although not necessarily close to touch, while interlock-related closing control commands that apply to the Locking units act in the locking sense, in one way further distance of the authentication element from the object become.
  • This can automatically ensure that the Object is accessible to the authorized user if he is located at this, and on the other hand the clamping units and thus the locking system as a whole to secure your access Take the locked state when the authorized User removed from the object.
  • the closing control commands generated automatically by the closing control means not just release or lock signals to release or blocking a locking or unlocking of a locking unit, but rather the ones that effect this locking and unlocking Locking and unlocking commands themselves.
  • the closing control commands generated automatically by the closing control means not just release or lock signals to release or blocking a locking or unlocking of a locking unit, but rather the ones that effect this locking and unlocking Locking and unlocking commands themselves.
  • a locking system developed according to claim 5 includes automatic relocking means which ensure that on the generation of a closing control command acting in the unlocking direction towards the end of a predeterminable waiting period Locking control command and generated so that the locking unit in question can be unlocked again secured state if moved while waiting no opening process of the associated access element has taken place and after the waiting time no legitimate Authentication element more in one to unlock-related Closing control commands belonging to the area of the outer detection zones, i.e. is no longer at an unlocking distance.
  • an automobile 1 with a shown as a keyless go system locking system The Locking system includes in conventional, not shown One locking unit each on the four vehicle doors 2, 3, 4, 5 and on a boot lid 6. Also conventional, not the clamping units are more suitable Closing control means assigned which the required closing control commands generate to the different clamping units between a locked state in which they are opening of the associated access element, i.e. one of the doors 2 to 5 or the rear lid 6, lock, and an unlocked state toggle in which the access element is actuated a corresponding opening control element, such as a door handle or trunk lid opening button, released by the user.
  • the authorized vehicle user enter correspondingly vehicle-specific coded authentication element with itself, e.g. in the form of a chip card. Its authorization for the vehicle is going through a wireless authentication process Data communication between the vehicle-side locking control means and the authentication element, e.g. about a radio link in the frequency band around 24GHz.
  • Authentication communication takes place in accordance with the keyless go operating philosophy the locking control means with an authentication element without further actuation of the same if this is within a predeterminable detection range from to this Detection sensors of the closing control means provided for the purpose is located, each of which has a detection sensor in the example considered is assigned to a clamping unit.
  • the authentication element detection sensors are also of conventional construction and typically each contain one in the area of the assigned Closing unit arranged antenna unit, the so-called Catchment area forms the detection area and over the of the closing control means covering the detection area Query signal emitted and when the authentication element is recognized Authentication communication carried out with this becomes.
  • the detection range of these detection sensors usually extends both with an internal detection zone in one part of the vehicle interior as well as in the form of an outer detection zone from the vehicle to a certain range to the outside.
  • Different closing control commands can be dependent be provided whether an authorizing authentication element recognized in the vehicle interior or in the vehicle exterior becomes. Only the behavior of the locking system is present upon detection of an authentication element in the vehicle exterior of interest.
  • the five detection sensors on the four vehicle doors 2 to 5 and on the trunk lid 6 five associated External detection zones 7, 8, 9, 10, 11 defined, which in are essentially free of overlaps.
  • the schematic figurative Representation is the freedom of overlap by four black marked dividing strips 12, 13, 14, 15 illustrated.
  • a region 16 likewise marked in black in front of the vehicle 1 also remains insensitive to any authentication elements located there.
  • Each outer detection zone is typically 7 to 11 in an inner distance zone 7a to 11a closer to the vehicle and one outer, remote vehicle distance zone 7b to 11b divided.
  • the inner and outer distance zones overlap, so that no unwanted dead zones occur and form a respective hysteresis transition area 7c to 11c.
  • An authentication element distance sensor system is coordinated with this in the locking control means provided with a provision the removal of a recognized authentication element from the vehicle 1 in any case to the extent that the closing control means can determine whether this is from one of the detection sensors recognized in its associated outside detection zone Authentication element in the inner or outer distance zone located.
  • the distance sensor system can do this from any conventional type, which is why here need not be discussed in more detail.
  • the locking control means then generate an authorization Authentication element closing control commands under other depending on whether the identified authentication element in one of the inner distance zones 7a to 11a or one of the outer distance zones 7b to 11b.
  • the closing control means are in the Location, if a recognized authentication element is recognized automatically locking or unlocking one or more or to effect all clamping units without the user this requires actuating a related control element.
  • the communication flow between the locking control means and a respective authentication element for the purpose of recognizing a such, determining its removal and testing its Authorization preferably includes a cyclical one Sending a polling carrier signal by the closing control means via the detection sensors and also a cyclical one Wake up Activate the respective authentication element. There is an awakened authentication element in the from Carrier signal covered detection area of one of the detection sensors, so it receives the carrier signal and gives a response signal back.
  • the closing control means recognize that and in which of the outer detection zones 7 to 11 is an authentication element is present and then use its distance sensors to determine whether the authentication element is in the relevant inner distance zone 7a to 11a or outer distance zone 7b to 11b.
  • the locking control means generate the locking or unlocking closing control command, which belongs to the distance zone in which the justifying Authentication element was recognized.
  • the closing control logic i.e. determining which closing control command depending on the current locking status of the locking units and depending on which distance zone which one External detection zone is an authoritative authentication element was recognized, can be varied and for the respective application choose coordinated. Representing further implementation options is a sample logic logic below specified.
  • the inner one directly to the Vehicle access elements adjacent distance zones 7a to 11a the generation of unlocking commands and the outer removal zones 7b to 11b the generation of locking commands assign, i.e. upon detection of an authoritative authentication element unlocking in an inner removal zone one or more clamping units and upon detection of one authorizing authentication element in an outer Distance zone a lock of one or more locking units to make.
  • a locking-closing control command all locking units in their locked State to move if they are not already in this you can select a global or for unlocking to enable selective unlocking.
  • global unlocking are generated when an unlocking closing control command is generated all locking units in the unlocked state offset while in the operating mode with selective unlocking only one by the unlock command generated in each case Closing unit is placed in its unlocked state, the belongs to the inner distance zone in which the justifying Authentication element was recognized. For switching is between these two unlocking modes preferably arranged on the respective authentication element Presetting control element provided.
  • the clamping units stay with them Authentication element approaching the vehicle from the outside for so long locked until the authorizing authentication element the respective Hysteresis overlap area 7c to 11c to the vehicle has left, i.e. completely inward from the outer Distance zone 7b to 11b has emerged. Analog remains with authentication element moving away from vehicle 1 at least unlocks the associated clamping unit until the Authentication element the associated hysteresis overlap area 7c to 11c has left the vehicle, i.e. Completely stepped outward from the inner removal zone 7a to 11a is.
  • Automatic relocking is another functionality intended. This consists of the closing control means one previously based on the recognition of an authoritative one Authentication element in an inner distance zone 7a to 11a automatically set the clamping unit in its unlocked state after a definable waiting time again in their locked Status is switched if there is no authoritative Authentication element is more in the inner distance zone and no opening of the relevant access element during the waiting time is done.
