Example 1
A vehicle remote control method for a new energy automobile leasing business is described in detail as follows:
1. remote management function on/off control information transmission and confirmation
(1) Remote control function for opening rental vehicle
Before the rental vehicle is delivered to a customer, a remote control function needs to be started, after the VCU is powered on, activated and self-checked, the control center sends a remote control function starting series instruction to the GPS terminal, and the terminal only needs to send a GPS CAN Message 1GPS _ Message1 once to send a starting password, GPS terminal unique identification information GPS ID and a Fixed Key signal derived from the GPS ID. After the VCU judges that the opening password is consistent with the self storage, the GPS ID, the Fixed Key and the remote control function opening state signal are stored as true three pieces of information, the vehicle reads the stored information every time, the VCU sends out the remote control function opening state signal by using a VCU CAN periodic Message 1VCU _ Message1, and the signal is simultaneously used as a trigger condition for realizing the second step of the function.
(2) Remote management and control function for closing rental vehicle
After the rental customer fulfills the commitment according to the contract, the vehicle closes the remote control function. After the VCU is powered on and activated and self-checked, the control center sends a remote control function closing series instruction to the GPS terminal, and the terminal only needs to send the GPS _ Message1 once to send a closing password Shutdown Code, a GPS ID and a Fixed Key. The VCU judges whether the Shutdown Code, the GPSID and the Fixed Key are consistent with the stored information, if so, the VCU closes the remote control, stores and sends a remote control function starting state signal to be false, the next time the low-voltage VCU reads the stored information, and after judging that the remote control function starting state signal is false, the VCU does not perform handshaking and forced vehicle locking judgment any more.
2. Handshake verification and vehicle travel control
After the remote control is started, after the vehicle is electrified at low voltage each time, the GPS terminal and the VCU perform handshake check, whether the GPS is replaced or detached is detected, and the VCU judges and controls the running action of the vehicle.
(1) VCU and GPS handshake check
After the VCU is electrified and activated and self-checked, a dynamic Seed is randomly generated, 200ms of delay is used for waiting for the GPS terminal to complete self-checking, then the Seed is sent to the GPS terminal through a VCU Message 2VCU _ Message2, after the terminal receives the Seed, the Seed and the FixedKey are synthesized, an MD5 algorithm is carried out, a calculated result takes partial bytes as a GPS terminal handshake key and returns to the VCU through a Message GPS _ Message2, the VCU uses the VCU handshake key obtained by the same combination and check algorithm to compare with the GPS terminal handshake key, and the comparison result is used as a basis for vehicle driving action.
(2) GPS terminal tamper judgment
And starting timing after the VCU sends the Seed, and after 1000ms, if the handshake key returned by the GPS is not received, judging that the GPS is removed or replaced, wherein the handshake fails, and the handshake verification failure times are increased by one.
(3) VCU limiting vehicle speed
1) If the comparison results are consistent, the VCU judges that the handshake verification is successful, the handshake verification failure times are reset, and the vehicle normally runs at high voltage;
2) if the comparison result is inconsistent, the VCU judges that the handshake check fails, the number of times of the handshake check fails is increased by one, the vehicle prompts a driver that the vehicle is in a locked state but not locked, if the handshake check passes when the key is powered on next time, the number of times of the handshake check fails is reset, and if the check does not pass, the VCU executes the locking: the vehicle speed is limited to 10 km/h.
3. Remote forced vehicle locking and vehicle running control
After the remote control is started, after the vehicle is electrified at low voltage, the VCU periodically detects whether the GPS sends a Message of forcedly locking the vehicle 3GPS _ Message3, and the VCU judges and controls the driving action of the vehicle.
(1) Remote forced vehicle locking function opening/closing control information transmission and confirmation
After the VCU is powered on and activated and self-checked, the control center sends a series of remote forced locking function opening/closing instructions to the GPS terminal, the terminal only needs to send a GPS CAN Message 3GPS _ Message3 once to send out a vehicle speed limiting value and GPS ID information, the VCU judges the consistency of the GPS ID and the GPS ID stored before, if the GPS ID is consistent with the GPS ID stored before, a vehicle speed limiting value signal in the Message is stored, meanwhile, whether the vehicle speed limiting value is less than 200km/h is judged, if the vehicle speed limiting value is true, the VCU stores a forced locking mark signal which is true information, the vehicle prompts a driver that the vehicle is locked but not locked, and the VCU forces the vehicle limiting action when the vehicle is powered on next time and the forced locking mark is determined to be true.
(2) VCU mandatory behavior management and control and emergency start
1) If the vehicle speed limiting signal is 0 and the current vehicle speed is less than 5 km/h: VCU limits upper high voltage;
2) if the vehicle speed limiting signal is 10 km/h: the VCU allows the vehicle to execute speed limit of 0 after running for a distance with the vehicle speed of 10km/h within 5 minutes after being electrified, the allowed electrified times are added with 1, if the vehicle is not forcibly locked in the next time, the VCU also executes a strategy of 10km/h within 5 minutes, the allowable times are accumulated for 3 times, and after the 3 rd time, the VCU directly executes the speed limit: 0, but not limited to upper high voltage and charge logic;
3) if the vehicle speed limiting signal is 200 km/h: the VCU turns off the forced locking function.
The invention can effectively prevent the situation that the rental customer removes the remote intelligent module or the remote intelligent module cannot lock the car due to poor signal reception; the vehicle manager can execute remote forced vehicle locking according to the rental contract fulfillment condition, and the vehicle after vehicle locking has the capability of emergently starting vehicle moving.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents or improvements made within the spirit and principle of the present invention should be included in the scope of the present invention.
