Description

Key system for electric vehicle
Technical field
The present invention relates to electric vehicle control field, more particularly to a kind of key system for electric vehicle.
Background technology
With the development of automobile industry, Intelligent key is increasingly popularized, and the requirement to Intelligent key is quickly solved from original Lock, accurate locking unlock till now；Intelligent key of the prior art, which exists, is intercepted by a third party signal analysis And replicate Intelligent key or replicate the unlocking signal of interception, so as to bring hidden danger to the anti-theft security of vehicle.
The content of the invention
, should it is an object of the invention to overcome the deficiencies of the prior art and provide a kind of key system for electric vehicle Key system is simple in structure, its transmission uses cipher mode, it is possible to reduce the leakage of information, stability are strong.
To achieve these goals, the technical solution adopted by the present invention is：A kind of key system for electric vehicle, its It is characterized in that：Including remote-control key, the base station of setting in the car, the base station and vehicle two-way communication, passed for data Defeated and identification, and transmission identification information is verified by Encryption Algorithm.Identification information is encrypted using keeloq cipher modes.
The base station includes low frequencies module, coding control module, coding control module coding output body Part checking information is simultaneously launched by low frequencies module.
The remote-control key includes low frequency reception module, key module, keeloq encrypting modules, high-frequency emission module, The base station further includes high-frequency reception module, keeloq deciphering modules；
The low frequency signal that the base station set on vehicle is sent is sent to key module, key module after low frequency reception module Authentication field in the information of reception is verified, and keeloq encrypting modules are controlled by key module after being proved to be successful Encrypted authentication information is exported, is launched via high-frequency emission module；
Feeding keeloq deciphering modules are decrypted information and will solve after high-frequency reception module in base station receives data Information after close is fed through coding control module and is identified, and vehicle unlock is controlled after identification success.
The coding control module control low frequencies module persistently sends low-frequency data；When coding control module is being set When not receiving any unlocking signal in the time interval put, base station enters resting state, and low frequencies module stops transmitting number According to.
When receiving trigger signal, resting state terminates, and trigger signal in Vehicular vibration, key module including arbitrarily pressing Key or vehicle produce certain trigger signal and wake up vehicle inducing function.
The advantage of the invention is that：Being communicated and transmitted using low frequency signal, penetrability is strong, and using the information after coding It is transmitted and the information of transmission is encrypted in Encryption Algorithm, that reduces that the Intelligent key information of appearance is stolen brings Risk；And when base station does not receive signal for a long time (24 interior when small do not receive any trigger signal), auto sleep, subtracts Few energy consumption.
Brief description of the drawings
Mark in the content and figure expressed below each width attached drawing of description of the invention is briefly described：
Fig. 1 is structure principle chart of the present invention.
Embodiment
It is further detailed to the embodiment work of the present invention by the description to optimum embodiment below against attached drawing Thin explanation.
As shown in Figure 1, a kind of key system for electric vehicle, including remote-control key, the base station of setting in the car, The base station and vehicle two-way communication, transmission identification letter is verified for data transfer and identification, and by Encryption Algorithm Breath.Identification information is encrypted using keeloq cipher modes.
Base station includes low frequencies module, coding control module, coding control module coding output authentication Information is simultaneously launched by low frequencies module.
Remote-control key includes low frequency reception module, key module, keeloq encrypting modules, high-frequency emission module, described Base station further includes high-frequency reception module, keeloq deciphering modules；The low frequency signal that the base station set on vehicle is sent connects through low frequency Receive module after be sent to key module, key module verifies authentication field in the information of reception, and verification into Encrypted authentication information is exported by key module control keeloq encrypting modules after work(, is launched via high-frequency emission module Go out；Feeding keeloq deciphering modules are decrypted information and by after decryption after high-frequency reception module in base station receives data Information be fed through coding control module and be identified, vehicle locking unlock is controlled after identification success.Coding-control mould Block control low frequencies module persistently sends low-frequency data；Take office when coding control module does not receive in the time interval of setting During what unlocking signal, base station enters resting state, and low frequencies module stops launching data.When receiving trigger signal, stop Dormancy state terminates, and trigger signal produces certain trigger signal including any button or vehicle in Vehicular vibration, key module and wakes up Vehicle inducing function.
Intelligent key system is divided into base station (burglar alarm mainframe) and transponder (remote-control key) two parts, system block diagram As shown in Figure 1.Two-way communication is taken between this two parts.The system has two kinds of working methods：
The first usual manner：It is that base station unit in vehicle ceaselessly sends a low-frequency data for being encoded to 125kHz Unit is to search and wake up a certain range of transponder.All transponders in the range of signal can receive the number According to, and the data field of coding unit is verified.Once the transponder with car owner identifies successfully, transponder will be automatic Send the radio frequency Keeloq coded datas that frequency is 315/433.92MHz, base station unit after the signal is received to its into Row decoding, if identified successfully, by control real vehicle lock or unlock.
Second of power save mode：Base station unit can't poll transponder in order to reduce current drain.Base station unit exceedes 24 it is interior when small do not receive any trigger signal, in a dormant state, could be waken up when only receiving trigger signal, should Triggering mode is by any button of remote controler, vibration vehicle or promotes the certain trigger signal wake-up vehicle of vehicle generation to sense work( Energy.
Obviously present invention specific implementation is not subject to the restrictions described above, as long as employing the methodology and skill of the present invention The improvement for the various unsubstantialities that art scheme carries out, within protection scope of the present invention.
