A kind of electric automobile starts authorization method
Technical field
The invention belongs to the startup authorization method in rent-a-car field, more particularly to lease electric car.
Background technology
With the development of society, automobile enters many families, but with the parking difficulty brought, your problem safeguarded so that very
More people are unwilling buying car and select public rent-a-car.Public rent-a-car has specific parking stall, it is not necessary to which user ties up
The advantages that shield and welcome extensively.
It is most in the market to use but the mandate of rent-a-car starts the important step of always electronic rent-a-car
The technical scheme of wire harness is reequiped, by controlling vehicle power supply to realize.Terminal control relay is controlled come real by mounted remote
The break-make of existing circuit.Mandate of this mode to rent-a-car starts method, although easy and effective, leasing company's needs pair
The automobile of purchase is reequiped, and increases wire harness to control the control of the power supply of electric automobile, increase cost and increase rent-a-car
Popularization difficulty.
The content of the invention
It is an object of the invention to provide a kind of startup authorization method of electric automobile, this method can be quick and easy by mobile phone
The mandate for realizing automobile starting, and need not to automobile carry out wire harness repacking, be easy to the popularization and development of electronic rent-a-car.
To achieve these goals, the technical scheme taken of the present invention is:A kind of electric automobile starts authorization method, including
Following steps,
(1) user terminal is communicated with rental server, and lease request is sent to rental server;
(2) rental server generation authorization message is respectively sent to TBOX and user terminal;
(3) user terminal is completed to communicate to connect by server and TBOX, verifies authorization message and drivers information, if both
It is verified, TBOX sends a signal to automobile VCU, unlocks automobile power, can now start automobile.
It is authorization code to be sent in step (2) to the authorization message of TBOX and user terminal, and authorization code is encrypted for symmetric key.
Step (3) includes,
(3-1) user terminal is communicated to connect by server and TBOX;
(3-2) user terminal inputs drivers information;
(3-3) user terminal sends drivers information and authorization message into TBOX, and TBOX is to receiving to rental server
The authorization message sent of authorization message and user terminal carry out to code, while the drivers information of user terminal input and lease service
What is stored in device contrasts with the one-to-one drivers information of user terminal, if passing through to code success and drivers information contrast,
Now TBOX sends power unblock authorization signal to VCU, unlocks automobile power, now can start automobile by automobile key.
Described TBOX is communicated to connect by CAN in Automobile and vehicle VCU.
Further comprise step
(4) vehicle-state is obtained, judges whether vehicle starts;
(5) it is not actuated in vehicle, judge vehicle whether there is start-up operation in time t, if nothing, vehicle VCU releases startup and awarded
Power, automobile No starting.
In step (5), if automobile starting or having start-up operation, release to start after automobile flameout and authorize, now car
No starting.
Time t is 10 minutes.Described user terminal is cell phone application.
The present invention's need not carry out wire harness repacking to automobile, can by mobile phone it is quick and easy realize automobile starting
Authorize, simplify automobile starting flow, improve vehicle reliability of operation and intelligent interconnection, be easy to pushing away for electronic rent-a-car
Wide and development.
Brief description of the drawings
This specification includes the following drawings, and shown content is respectively:
Fig. 1 is the flow chart of the automobile starting authorization method of the present invention;
Embodiment
Below against accompanying drawing, by the description to embodiment, embodiment of the invention is made further details of
Explanation, it is therefore an objective to help those skilled in the art to have more complete, accurate and deep reason to design of the invention, technical scheme
Solution, and contribute to its implementation.
A kind of electric automobile starts authorization method, comprises the following steps,
(1) user terminal is communicated with rental server, and lease request is sent to rental server;
(2) rental server generation authorization message is respectively sent to TBOX and user terminal;
(3) user terminal communicates with TBOX, verifies authorization message and drivers information, if both of which is verified, TBOX hairs
The number of delivering letters unlocks automobile power, can now start automobile to automobile VCU.
(4) vehicle-state is obtained, judges whether vehicle starts;
(5) it is not actuated in vehicle, judge vehicle whether there is start-up operation in time 10min, if nothing, vehicle VCU is released and opened
It is dynamic to authorize, automobile No starting.If automobile starting has start-up operation, released after automobile flameout and start mandate, now car
No starting.After receiving blocking order in 10 minutes, cancel and start authorized order, auto Not Permitted starts.
It is authorization code to be sent in step (2) to the authorization message of TBOX and user terminal, and authorization code adds for symmetric key
It is close.
Step (3) includes,
(3-1) user terminal communicates to connect with TBOX;
(3-2) user terminal inputs drivers information;
(3-3) user terminal sends drivers information and authorization message into TBOX, and TBOX is to receiving to rental server
The authorization message sent of authorization message and user terminal carry out to code, while the drivers information of user terminal input and lease service
What is stored in device contrasts with the one-to-one drivers information of user terminal, if passing through to code success and drivers information contrast,
Now TBOX sends power to VCU by CAN and unlocks authorization signal, unlocks automobile power, can now pass through automobile key
Spoon startup automobile.
As shown in figure 1, client communicates with TBOX, it is first determined whether having logged in, if having logged in, control instruction is sent
To TBOX, RVM is activated;If being not logged in input username and password to be logged in, control instruction is sent after logging in TBOX, is swashed
RVM living;After RVM is activated, client carries out communication completion with TBOX, and TBOX receives the authority checking packet that client is sent
Authorization message and drivers information are included, and is sent after being verified to VCU and starts authorized order, VCU receives startup mandate and referred to
After order, automobile be in can starting state, ignition switch gets to START shelves automobile startings, and VCU obtains the letter whether vehicle starts
Breath, can be determined by obtaining the state of automobile drive electric motor.After automobile starting, feedback vehicle is in carrying for vehicle condition
Show to client, if automobile is not actuated, whether detection by start-up operation, start-up operation can detect ignition switch shape in 10 minutes
State information, if without start-up operation in 10 minutes, feedback information of the automobile without start-up operation is into client, if having in 10 minutes
Start-up operation, detect vehicle condition, after automobile flameout, cancel start authorize, automobile be in can not starting state, feed back simultaneously
Automobile the information in flameout state to client." flame-out " state of electric automobile can be by detecting automobile starting key
The state of spoon, when automobile key turns to closing automobile power supply, then it is assumed that automobile " flame-out ".
The present invention is exemplarily described above in association with accompanying drawing.Obviously, present invention specific implementation is not by above-mentioned side
The limitation of formula.As long as employ the improvement of the various unsubstantialities of inventive concept and technical scheme of the present invention progress;Or not
It is improved, the above-mentioned design of the present invention and technical scheme are directly applied into other occasions, in protection scope of the present invention
Within.
