Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the drawings of the embodiments of the present invention. It is to be understood that the embodiments described are only a few embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the described embodiments of the invention, are within the scope of the invention.
The following first describes a vehicle remote encryption unlocking control method according to an embodiment of the invention with reference to the accompanying drawings.
The vehicle remote encryption and unlocking control method provided by the embodiment of the invention comprises the following steps: storing the sequence number in a memory of the T-BOX 10; writing a T-BOX10 ID serial number matched with the serial number in the vehicle body control module 20; the mobile phone APP30 sends an unlocking instruction; the cloud 40 receives the unlocking instruction and sends the unlocking instruction to the T-BOX10, the T-BOX10 preliminarily judges the unlocking condition, if the unlocking condition is met, a safety certification and unlocking request message is sent to the vehicle body control module 20, the vehicle body control module 20 receives and corrects the safety certification request, and if the safety certification request conforms to the sequence number and the password, the unlocking request instruction is executed.
Specifically, as shown in fig. 1, a user sends an unlocking instruction to the cloud 40 through the mobile phone APP30, the cloud 40 receives the instruction and then sends the instruction to the T-BOX10 through the 4G network, the T-BOX10 first judges an unlocking condition, and sends a bus message to wake up the whole vehicle and send an unlocking request instruction at the same time when the condition is met. Generally, an unlocking request command is transmitted through a CAN bus, and the vehicle body control module 20 executes an unlocking action after receiving an unlocking request sent by the T-BOX10, but when an illegal simulation T-BOX10 node sends the same signal command, the vehicle body control module 20 CAN still be unlocked, so that potential safety hazards exist. In order to solve the problem, as shown in fig. 2, the authentication and encryption function is added in signal transmission, a unique serial number is stored in a memory (EEPROM) when the T-BOX10 leaves the factory, a matching T-BOX10 ID serial number is written in the vehicle body control module 20, and when the vehicle body control module 20 receives the serial number + a password (the initial password may be 6 digits), it is determined that the unlocking information sent by the ID is valid, and an unlocking request instruction is executed.
Therefore, according to the vehicle remote encryption unlocking control method provided by the embodiment of the invention, the safety verification process is added between the T-BOX10 and the vehicle body control module 20, the vehicle safety is improved, and the encryption mode is simple.
According to one embodiment of the invention, the messages sent by the T-BOX10 are event type messages.
Specifically, in order to prevent the message from being illegally intercepted and encrypted information from being leaked, the message sent by the T-BOX10 is defined as an event message, and an unlocking request message is sent to the vehicle body control module 20 only when an unlocking instruction of the mobile phone APP is received, so that the safety level is greatly improved. The encryption strategy does not need complex authentication flow and encryption algorithm, and the bus message information does not need to be encrypted, so that the authentication time is saved, and the unlocking real-time performance is good.
In one embodiment of the present invention, the T-BOX10 ID serial number is written to the body control module 20 by the diagnostic device. That is, the diagnostic apparatus writes the T-BOX10 ID serial number matching therewith in the vehicle body control module 20 when the vehicle is off-line.
Optionally, the T-BOX10 is connected through a diagnostic to write a T-BOX10 ID serial number at the body control module 20.
In other words, as shown in fig. 3, when the vehicle is off-line, the diagnostic instrument is connected to the T-BOX10 at the integrated circuit inspection station, writes the vehicle VIN (vehicle identification code) and reads the serial number of the T-BOX10, the diagnostic instrument writes the serial number into the vehicle body control module 20, and the vehicle body control module 20 stores the serial number. By designing the automatic matching scheme of the vehicle body control module 20, automatic matching can be guaranteed after a T-BOX10 module is additionally arranged in a post-assembly market, and convenience is brought to replacement of the T-BOX10 after sale.
Preferably, the password is modified by the cell phone APP 30.
That is to say, the user can set up the communication password through cell-phone APP30, and after the setting is accomplished, T-BOX10 sends this password to automobile body control module 20, and automobile body control module 20 carries out the record.
In summary, according to the vehicle remote encryption and unlocking control method provided by the embodiment of the invention, the safety verification process is added between the T-BOX10 and the vehicle body control module 20, so that the vehicle safety is improved, and the encryption mode is simple.
The vehicle remote encryption unlocking control system according to the embodiment of the second aspect of the invention comprises a T-BOX10, a vehicle body control module 20, a mobile phone APP30 and a cloud 40.
Specifically, as shown in fig. 1 to 3, a serial number is stored in a memory of the T-BOX10, a T-BOX10 ID serial number matched with the serial number is written in the vehicle body control module 20, the mobile phone APP30 is used for sending an unlocking instruction, the cloud 40 receives the unlocking instruction and sends the unlocking instruction to the T-BOX10, the T-BOX10 preliminarily determines an unlocking condition, if the unlocking condition is met, a security authentication and unlocking request message is sent to the vehicle body control module 20, the vehicle body control module 20 receives and corrects the security authentication request, and if the security authentication request meets the serial number and the password, the unlocking request instruction is executed.
Preferably, the message sent by the T-BOX10 is an event type message.
According to one embodiment of the present invention, the T-BOX10 ID serial number is written to the body control module 20 by the diagnostic equipment.
According to yet another embodiment of the present invention, a T-BOX10 ID serial number is written to the body control module 20 by a diagnostic connection to the T-BOX 10.
In summary, according to the vehicle remote encryption and unlocking control method provided by the embodiment of the invention, the safety verification process is added between the T-BOX10 and the vehicle body control module 20, so that the vehicle safety is improved, and the encryption mode is simple.
The vehicle comprises the vehicle remote encryption and unlocking control system according to the embodiment of the invention, and the vehicle remote encryption and unlocking control system according to the embodiment of the invention has the technical effects, so the vehicle according to the embodiment of the invention also has the corresponding technical effects, and the vehicle safety is improved.
Other structures and operations of the vehicle according to the embodiment of the present invention will be understood and readily implemented by those skilled in the art, and thus will not be described in detail.
