Description
Technical field
The utility model is related to the technical fields of Automobile Design and Manufacturing, and more specifically, the utility model is related to one kind
Back door intelligent opening system.
Background technology
For back door intelligent opening system mainly by kicking sensor, tailgate electronic drive unit (tailgate ECU) is electronic at present
Strut, Intelligent key and keyless entry and startup electronic drive unit (PEPS ECU) form, and are acquired by kicking sensor
Signal be sent to tailgate ECU, while PEPS ECU are matched with key, and signal is passed to tailgate ECU, tailgate ECU
The signal for handling receiving by analysis sends out instruction, and drives the electronic strut of tailgate, makes opening and closing of back door, but since foot kicks sensing
Device can not be recognised that really completely to be operated for people's foot, is existed accidentally using toy or other articles as the input of signal,
Cause tailgate to open by mistake, brings inconvenience or accident.
Utility model content
In order to solve above-mentioned technical problem in the prior art, the purpose of this utility model is to provide a kind of back door intelligence
It can open system.
A kind of back door intelligent opening system, it is characterised in that：Including key, keyless entry and start electric drive list
Member, tailgate electronic drive unit, electronic strut, tailgate, camera and man-machine interface；The camera is connected to human-machine interface
Mouthful, man-machine interface is connected to the tailgate electronic drive unit by CAN bus, and the key is connected to keyless entry and opens
Dynamic electronic drive unit, the keyless entry and startup electronic drive unit are connected to the tailgate electronics by CAN bus
Driving unit；The tailgate electronic drive unit is connected to the electronic strut, and the electronic strut is for driving the tailgate.
Compared with prior art, there are following advantageous effects for the back door intelligent opening system of the utility model：
The back door intelligent opening system of the utility model carries out recognition of face by camera, can specify people's
It is intended to, realizes tailgate intelligent opening, avoid the problem of opening by mistake.
Description of the drawings
Fig. 1 is the structure diagram of the back door intelligent opening system of embodiment 1.
Fig. 2 is the structural schematic diagram of the PTC controllers in back door intelligent opening system.
Specific implementation mode
Back door intelligent opening system described in the utility model is further explained below with reference to specific embodiment
It states, to help those skilled in the art to the design of the utility model of the utility model, that technical solution has is more complete, accurate and deep
The understanding entered.
Embodiment 1
As shown in Figure 1, the back door intelligent opening system of the present embodiment, including key, keyless entry and startup electronics
Driving unit (PEPS ECU), tailgate electronic drive unit (tailgate ECU), electronic strut, tailgate, camera and man-machine interface
(HMI)；The camera is connected to man-machine interface, and man-machine interface is connected to the tailgate electronic drive unit by CAN bus
(tailgate ECU), the key are connected to keyless entry and start electronic drive unit (PEPS ECU), the keyless entry
The tailgate electronic drive unit (tailgate ECU) is connected to by CAN bus with electronic drive unit (PEPS ECU) is started；Institute
It states tailgate electronic drive unit (tailgate ECU) and is connected to the electronic strut, the electronic strut is for driving the tailgate.Tool
For body, the back door intelligent opening system of the present embodiment carries out recognition of face by camera, and HMI sends signal after confirming
Give tailgate ECU, at the same PEPS ECU matched with key after signal is also sent to tailgate ECU, tailgate ECU will be received
Signal is handled, and signal is sent out, and drives the electronic strut of tailgate, to opening and closing of back door.Fig. 2 shows the matching streams of PEPS ECU
Journey is to detect the relative position between Intelligent key and PEPS ECU by low-frequency antenna, and pass through high and low frequency signal (height
Frequency 433.92MHz, low frequency 125KHz) effective two-way interactive communication is set up between ECU and Intelligent key, according to ECU to intelligence
The authentication that energy key carries out is as a result, decide whether that sending execution signal gives tailgate ECU.So-called low frequency signal wakes up, with PE
Refer to when driver gives one trigger signal of PEPS system, ECU can switch to work shape from sleep state for system
State, and a key is sent to Intelligent key by low-frequency antenna and wakes up message, when key is received by the low-frequency antenna of itself
After this message, message will be verified by the intelligent chip of itself, such as the data match that verification result and key store,
Intelligent key is then waken up；And high-frequency signal verification refer to then after Intelligent key is waken up, can by the ID identity codes of itself with
The form of high-frequency signal is sent to PEPS ECU, if PEPS ECU identify that the key code of this ID number and own system matches
When, identifying code will be sent to Intelligent key by low frequency signal, the Intelligent key for receiving identifying code can be by specifically redirecting
Code algorithm carries out data encryption to the identifying code, and encrypted result is beamed back PEPS ECU by high-frequency signal.The latter can will receive
To encryption data be compared with the result of calculation of itself, such as both matching, will be total by CAN by corresponding operational order
Line is sent to tailgate ECU, and tailgate ECU is confirmed whether it is that driver operates and decides whether to pass through execution by man-machine interface HMI
Electronic strut opens tailgate.The back door intelligent opening system of the present embodiment carries out recognition of face by camera, can define
The intention of people realizes tailgate intelligent opening, avoids the problem of opening by mistake.As the intelligence system on vehicle continues to develop,
In the case of cost is acceptable, the back door intelligent opening system of the present embodiment can be increased on vehicle.
For the ordinary skill in the art, specific embodiment has only carried out exemplary retouch to the utility model
It states, it is clear that the utility model specific implementation is not subject to the restrictions described above, as long as using the methodology of the utility model
The improvement of the various unsubstantialities carried out with technical solution, or it is not improved that the design of the utility model and technical solution is direct
Applied to other occasions, it both is within the protection scope of the present invention.
