Specific embodiment
It is described in detail below in conjunction with specific embodiment of the attached drawing to the disclosure.It should be understood that this place is retouched
The specific embodiment stated is only used for describing and explaining the disclosure, is not limited to the disclosure.
Fig. 1 is the schematic block diagram of the communication control unit 100 of vehicle and car key shown according to an exemplary embodiment,
The device 100 is applied to vehicle, as shown in Figure 1, the device 100 includes the first receiving module 10 and parsing module 20.
First receiving module 10, for receiving the signal of car key transmission, which includes multiple data frames and described more
The transmission frequency of a data frame is identical, and the transmission frequency is default center frequency or is comprised in the multiple data
In the header of the first data frame in frame.
The signal that car key is sent can be high-frequency signal, send frequency can be such as 315MHz, 433.92MHz or
Other higher frequencies.
The multiple data frame can be such as three data frames.Wherein, the transmission frequency of these three data frames is identical, i.e.,
It can all be such as 315MHz that it, which sends frequency,.It will be apparent to a skilled person that 315MHz is example, and do not have to
To limit the disclosure.In addition, three data frames are also only examples, in fact, car key can be in the single with vehicle communicates
The data frame of other quantity is sent to increase system reliability.
Parsing module 20 is then default center frequency in the transmission frequency of multiple data frames or is comprised in multiple data
The processing mode for taking following two different in the case where in the header of the first data frame in frame:
(1) situation about being comprised in the transmission frequency of multiple data frames in the header of the first data frame of multiple data frames
Under, the header of first data frame is parsed to obtain the transmission frequency, and reside in the transmission frequency parsed
The message of the multiple data frame is parsed.
In the prior art, each data frame has header in multiple data frames, and the transmission frequency of each data frame is not
It is identical, therefore vehicle needs parse the header of each data frame to obtain the transmission frequency of each data frame.And
In the present embodiment, the transmission frequency of multiple data frames is identical and only adds header in the first data frame in multiple data frames,
To store the transmission frequency of all data frames in this communication, this, which is also meaned that, was communicated in vehicle with this of car key
Cheng Zhong, parsing module 20 only need the header of a data frame in the signal received to the first receiving module 10 to parse
Then the transmission frequency that multiple data frames in this communication can be obtained can reside in parsed transmission frequency to the
As soon as the signal that receiving module 10 receives carries out packet parsing, then vehicle can carry out corresponding function according to the message parsed
It can response.
(2) it in the case where the transmission frequency of multiple data frames is the default center frequency, resides in described preset
The message of the multiple data frame is parsed on frequency of heart.
When the transmission frequency of multiple data frames is default center frequency, without carrying out additional parsing work to transmission frequency
Make, parsing module 20 can reside directly in the signal received in default center frequency to the first receiving module 10 and solve
Analysis, to obtain useful message, then vehicle can carry out corresponding functional response according to the message.
Through the above technical solutions, the transmission frequency of multiple data frames in the signal that car key is sent is identical, and the hair
Sending frequency is also just meaned in the header of default center frequency or the first data frame being comprised in the multiple data frame
Be served only for the header not comprising any useful information of frequency detecting without increasing in the signal that sends of car key, or only need
To increase a header in the first data frame in multiple data frames for carrying the transmission frequency of this communication, thus can
The time span for reducing the signal that car key issues in a communication process, reduces the power consumption of car key, extends car key
Battery；In addition, vehicle does not need each of the signal sent to car key data frame poll header information yet,
It can be resided directly in by parsing module 20 and message is carried out to the signal that the first receiving module 10 receives in default center frequency
Parsing, or header only is carried out to the first data frame in the signal and parses to obtain transmission frequency, then stayed by parsing module 20
It stays in the transmission frequency parsed and message is parsed, this makes it possible to the sound for reducing the signal that vehicle issues car key
Between seasonable, user's operation is quickly responded.
Optionally, the default center frequency can be just respectively stored in vehicle and car key in vehicle release,
In this way, in vehicle is communicated with the single of car key, car key can send multiple data frames with default center frequency, and vehicle
Multiple data frames, the parsing module that first receiving module 10 of side then can directly be sent with default center frequency reception car key
20 can reside directly in the multiple data frames received in default center frequency to the first receiving module 10 and demodulate etc.
Parsing operation.For example, default center frequency is set to 315MHz when vehicle release, then communicated in car key with the single of vehicle
In, car key sends multiple data frames to vehicle with the transmission frequency of 315MHz, and vehicle side is also directly according to the reception of 315MHz
Frequency parses the multiple data frames received to receive multiple data frames of car key transmission and reside on 315MHz.
Certainly, default center frequency may be used also other than it can be respectively stored in when leaving the factory in vehicle and car key
To be sent to car key by vehicle in each communication process of vehicle and car key, implementation is as shown in Figure 2.
Fig. 2 is the schematic block of the communication control unit 100 of the vehicle shown according to a further exemplary embodiment and car key
Figure, the device 100 are applied to vehicle.As shown in Fig. 2, the device 100 is in addition to including the first receiving module 10 as shown in Figure 1
It further include the first sending module 30 except parsing module 20, for being the default center frequency in the transmission frequency
In the case of, Xiang Suoshu car key sends authentication information, which includes the default center frequency.
For example, when vehicle needs to realize keyless entry (Passive Keyless Entry, PKE) or opens without key
When function as dynamic (Passive Keyless Start, PKS), vehicle needs to be authenticated between car key, at this time vehicle
It just needs to send authentication information to car key, and includes the default center frequency in authentication information.Car key is receiving
To after the authentication information, it will be able to it is corresponding with vehicle progress to authenticate, and using the default center frequency as send frequency to
Vehicle sends the signal comprising multiple data frames, and the first receiving module 10 in vehicle is then using the default center frequency as reception
To receive, the signal of car key transmission, parsing module 20 then resides in the default center frequency and parsed frequency.
In a kind of possible embodiment, first sending module 30 is in the form of low frequency signal to the car key
Send the authentication information.The frequency of the low frequency signal can be 123KHz to any frequency between 128KHz, preferably
125KHz.In addition, the first sending module 30 can be such as low-frequency antenna.Being sent in the form of low frequency signal to car key
The authentication information can reduce the cost of vehicle, and can reduce the power consumption of vehicle and car key.
Fig. 3 is the schematic block of the communication control unit 100 of the vehicle shown according to a further exemplary embodiment and car key
Figure, the device 100 are applied to vehicle.As shown in figure 3, the device 100 is in addition to including the first receiving module 10 shown in Fig. 2, solution
It analyses except module 20 and the first sending module 30, further includes control module 40, for being in described preset in the transmission frequency
In the case where frequency of heart, the letter that first receiving module 10 is sent with car key described in the default center frequency reception is controlled
Number.The control module 40 can be also used for the first sending module 30 of control and send authentication information to car key.
No matter the default center frequency is included in is sent in the authentication information of car key by the first sending module 30
Or it is pre-stored in vehicle and car key in vehicle release, as long as car key is sent to the transmission frequency of the signal of vehicle
Rate is the default center frequency, and control module 40 can control the first receiving module 10 with the default center frequency reception
The signal that car key is sent.
It is connect through the above technical solutions, control device 40 controls first receiving module 10 with the default center frequency
The signal that the car key is sent is received, thus vehicle can be enabled quickly right when the transmission frequency is default center frequency
The signal that car key issues is responded, and vehicle is enabled quickly to respond user's operation.
In a kind of possible embodiment, the number of the default center frequency be it is multiple, the control module 40 is also
For in repeatedly communicate of the vehicle and the car key, control in a circulating manner using the multiple default center frequently
Rate.By, in a circulating manner using multiple default center frequencies, and repeatedly leading in repeatedly communicate of control vehicle and car key
It is compared using the same default center frequency always in letter, can be communicated between vehicle and car key and increase certain safety
Property.
For example, the number of default center frequency is such as 3, it is respectively F1, F2 and F3.Then, in vehicle and vehicle key
In the first time communication process of spoon, control module 40 controls the first sending module 30 and sends authentication information, the certification to car key
Information includes the vehicle frequency information F1 that this is communicated with car key, in this way, car key just using frequency F1 as send frequency to
Vehicle sends multiple data frames；In addition, control module 40, which also controls the first receiving module 10, receives vehicle key to receive frequency F1
Multiple data frames that spoon is sent, parsing module 20 then reside directly in the data received on frequency F1 to the first receiving module 10
Frame is parsed.Then, in second of communication process of vehicle and car key, communication process and first time communication process class
Seemingly, the centre frequency that only control module 40 can control this communication is F2.In this way, in the multiple communication of vehicle and car key
In, the centre frequency communicated every time will be recycled according to the sequence of F1-F2-F3.It will be apparent to a skilled person that pre-
If the number 3 of centre frequency is only example, the embodiment of the present disclosure is without limitation.
In addition, the message after parsing outgoing packet, can be fed back to control module 40, then control mould by parsing module 20
Block 40 understands the corresponding information of other module feedbacks to vehicle in order to which other modules execute corresponding function.If control module
40 are not received by the message of the feedback of parsing module 20 within a preset time, then illustrate this communication failure.
The specific example that vehicle realizes keyless entry or the communication process without key starting is given below, so that this field
Technical staff is easier to understand the thought of the embodiment of the present disclosure.
(1) firstly, control module 40, which controls the first sending module 30 (such as low-frequency antenna), issues 125KHz to car key
Low frequency signal form authentication information, in the authentication information in addition to it is basic with other than the information of car key certification, further include vehicle
The centre frequency F1 that key is this time communicated with vehicle, and control module 40 goes back while controlling the reception frequency of the first receiving module 10
Rate is fixed as frequency F1.
(2) then, it after car key receives the authentication information, is authenticated accordingly, and according to frequency F1 to vehicle
Issue corresponding high-frequency signal (for example including the identical data frame of three frames).
(3) secondly, the high-frequency signal that the first receiving module 10 of vehicle is fed back with the car key to be received such as frequency F1, receives
To after the high-frequency signal, is resided on frequency F1 by parsing module 20 and the high-frequency signal that first receiving module 10 receives is carried out
Parsing, the other control systems being sent to after parsing in control module 40 or vehicle, such as entire car controller etc..
(4) then, by the other control systems (such as entire car controller) in control module 40 or vehicle according to parsing
High-frequency signal after module 20 parses responds relevant function；If pre- after the first sending module 10 sends authentication information
If in time threshold, control module 40 is not received by the high-frequency signal of car key feedback, then this communication failure is judged.In reality
Now without key starting during, when judging communication failure, can by showing text or image on screen in the car, or
Person prompts driver by interior voice.
(5) finally, after this communication process terminates, control module 40 by next time communication default center frequency according to
Frequency cycle sequence F1-F2-F3 is set as next frequency of F1 in the sequence, i.e. the default center frequency of communication next time is
F2。
In a kind of possible embodiment, the number of the default center frequency be it is multiple, the control module 40 is also
For in repeatedly communicate of the vehicle and the car key, control in a random way using the multiple default center frequently
Rate.For example, if default center frequency is F1, F2, F3, the control module 40 can control with F2-F1-F3-F1 or
The various random orders such as F1-F2-F2-F1-F3 are come using the multiple default center frequency.This random manner can be into
One step improves the safety communicated between vehicle and car key.
