Description
Technical field
This utility model relates to a kind of vehicle electronic key for passive entry system and lacks alarm module.
Background technology
Passive type entrance system has been widely used in recent years.
Automobile passive type enters system and refers to that autoist unlocks in the case of button the most actively pressing electron key,
As long as leaving behind, automobile door handle just can automatically open up car door.Its key component has and has low frequency reception and high-frequency emission function
Electron key, there is low frequencies and the electronic control unit of high-frequency reception function, low frequency transmission antenna and door handle.
It is that, when pulling open automobile door handle, automobile receives the finger of enabling that automobile passive type enters the basic process of system
Order, in the coil being made by door handle, sends low frequency signal to electron key.Electron key receives low frequency signal, and sentences
This signal intensity disconnected.After determining the position of oneself, send wireless high-frequency instruction to automobile, it is achieved the automatic solution of arrangements for automotive doors
Lock.As long as so carrying with electron key, it is not necessary to draw out key and can be achieved with automobile entrance.
But, when electron key is carried over vehicle, in how reminding car owner's car, become this area skill without effective electron key
Art personnel's problem demanding prompt solution.
Utility model content
In order to overcome above-mentioned technological deficiency, the purpose of this utility model is to provide one in vehicle passive entry system,
When electron key is carried over vehicle, alarm can be sent passive for vehicle with remind in car owner's car without effective electron key
The electron key disappearance alarm module of entrance system.
The invention discloses a kind of electron key for vehicle passive entry system and lack alarm module, comprising: car
Body control unit, it communicates to connect with vehicle passive entry system, for being additionally related to multi-functional passive entry to vehicle based on user's closed door
System sends and closes gate signal；Unit searched by key, and it communicates to connect with vehicle passive entry system, for being additionally related to multi-functional passive entry at vehicle
System receives after closing gate signal, vehicle passive entry system drive this key to search unit searches the electronics activating in vehicle
Key, the electron key being activated sends effective key signal to vehicle passive entry system；And alarm unit, it is positioned at car
In passive entry system, it is used for receiving described effective key signal, and, judge whether according to the value of this effective key signal
Send alarm signal.
Preferably, effective key signal of described vehicle passive entry system electron key in the vehicle be recorded and
It is stored as initial value, when the electron key in vehicle is wholly or partly taken out of vehicle and based on user's closed door by user
And again sent to vehicle passive entry system by described vehicle body control unit and close gate signal, vehicle passive entry system drives again
Dynamic described key is searched unit searches and activates the electron key in vehicle, and the electron key being activated in vehicle is by effective key
Signal feeds back to vehicle passive entry system and is recorded and stored as changing value, the more described initial value of described alarm unit and
Changing value, if both differ, then described alarm unit will send alarm signal.
Preferably, also include closing car in the electron key taking vehicle out of being taken back vehicle as user and based on user
Behind the door, described changing value will then revert to described initial value.
Further, also including: also include: power supply IGN unit, it communicates to connect with vehicle passive entry system, is used for
Drive described alarm unit.
Further, also including: memory element, it is positioned in vehicle passive entry system, with record and store described at the beginning of
Initial value and changing value.
Preferably, described key is searched unit and is included some low-frequency antennas, for searching for low frequency signal form and activate
Electron key in vehicle.
Preferably, described alarm signal is acoustical signal, optical signal or both combinations.
The electron key for vehicle passive entry system of the present invention lacks alarm module can efficiently and conveniently allow use
Whether family exists whole effective electron keys in knowing vehicle before and after vehicles passing in and out, when giving electron key for change, it is possible to side
Just verify this electron key given for change the most really by the electron key lacked, safe and reliable and Consumer's Experience is good.
Accompanying drawing explanation
Fig. 1 is the system architecture diagram of this utility model better embodiment.
Detailed description of the invention
Of the present utility model advantage is expanded on further below in conjunction with accompanying drawing and specific embodiment.
Refer to Fig. 1, it illustrates the system architecture diagram of this utility model better embodiment.At this utility model relatively
Under good embodiment, the electron key for vehicle passive entry system of the present utility model lacks alarm module and includes: car
Unit searched by body control unit 101, passive entry system 102 and key；Wherein, key is searched unit and is specially some low frequency skies
Line 103.Vehicle body control unit 101, low-frequency antenna 103 all communicate with passive entry system 102 and are connected.Passive entry system
102 farther include memory element and alarm unit.
Some electron keys 104, such as two electron keys, together enter in vehicle with user, based on user's closed door
Action and trigger vehicle body control unit 101 to passive entry system 102 send close gate signal；Passive entry system 102 receives
After closing gate signal to this, it drives low-frequency antenna 103 with the search of low frequency signal form and to excite two electricity in vehicle further
Sub-key 104, two electron keys 104 being activated send effective key signal to passive entry system 102 therewith, passively enter
Enter the memory element in system 102 i.e. record and store this effective key signal and be endowed an initial value.
When the one of two electron keys 104 together leaves vehicle with user, action based on user's closed door and by
Described vehicle body control unit 101 again sends to passive entry system 102 and closes gate signal, and passive entry system drives low frequency again
The electron key in vehicle, now, its two quilt of two electron keys 104 being left in vehicle are searched for and activated to antenna 103
Activate and its effective key signal is fed back to passive entry system 102, the memory element in passive entry system 102 i.e. record
With store this effective key signal be endowed a changing value.
When power supply IGN unit is opened, alarm unit will compare changing value and initial value, if both differ
Sample, i.e. finds that the one of two electron keys 104 is carried over vehicle, then alarm unit is by alert.This alarm signal
Breath is acoustic and light information.
After the one of two electron keys 104 together returns to vehicle with user, the electron key that this is brought back in car will
Together be activated the effective key signal concurrently made new advances with the electron key being left in car, and this signal is remembered by memory element again
Address book stored is also endowed another changing value, if this changing value is identical with initial value, then will be updated to initially by changing value
Value thus alarm decision next time can be carried out, meanwhile, also demonstrate this electron key being brought back in car and be and stay before
Electron key in car.
It should be noted that, embodiment of the present utility model has preferably implementation, and not this utility model is appointed
The restriction of what form, any one skilled in the art changes possibly also with the technology contents of the disclosure above or is modified to
Same effective embodiment, as long as without departing from the content of technical solutions of the utility model, according to technical spirit pair of the present utility model
Any amendment that above example is made or equivalent variations and modification, all still fall within the range of technical solutions of the utility model.
