Description

Vehicle-mounted information updating method and device and storage medium
Technical Field
The present invention relates to the field of communications, and in particular, to a method and apparatus for updating vehicle-mounted information, and a storage medium.
Background
With the rapid development of automobiles toward multifunction, in automobile development, testing, production and after-sales, it is often necessary to update on-board information to meet the diversity demands of users. However, in the process of updating the vehicle-mounted information, when the vehicle-mounted controller fails, the instruction pointer may accidentally jump to the entry of the flash erasing function in the controller, so that normal software data is erased, and the application of the vehicle-mounted application program is affected.
In the related art, in the process of updating the vehicle-mounted information, an upper computer issues a flash erasing function of a stored flash driver binary file to a processor. The processor loads the flash erasing function into a random access memory (random access memory, RAM) to realize the refreshing and updating of the vehicle-mounted information. Because the controller needs to download the Flash driver again when the vehicle-mounted information is updated each time, the vehicle-mounted information is updated in a complex way, and the waste of transmission flow is caused. Therefore, how to improve the efficiency of the vehicle information update is a technical problem that remains to be solved.
Disclosure of Invention
The application provides a vehicle-mounted information updating method, device and storage medium, which are used for improving the efficiency of vehicle-mounted information updating. The technical scheme of the application is as follows:
according to a first aspect of the present application, there is provided a vehicle-mounted information updating method, including: the vehicle-mounted controller determines first vehicle-mounted information to be updated of a target application program; the vehicle-mounted controller receives a secret key from the upper computer; the vehicle-mounted controller decrypts a first Flash erasing function stored in the vehicle-mounted controller in advance based on the secret key to obtain a second Flash erasing function; the first Flash erasing function is an encrypted function; and the vehicle-mounted controller calls a second Flash erasing function and updates information in the target application program based on the first vehicle-mounted information to be updated.
According to the technical means, the upper computer sends first vehicle-mounted information to be updated to the vehicle-mounted controller and sends the secret key to the vehicle-mounted controller. The first Flash erasing function stored in the vehicle-mounted controller in advance is decrypted based on the secret key, so that a second Flash erasing function is obtained; the first Flash erase function is an encrypted function. In this way, the vehicle-mounted controller decrypts the second Flash erasing function which can be directly called to run based on the first Flash erasing function and the secret key which can not be directly called to run. That is, before the in-vehicle controller receives the key, the first Flash erasing function stored in advance in the in-vehicle controller is data that cannot be directly called for operation. Thus, even if the instruction pointer accidentally jumps to the entry of the first flash erase function, the first flash erase function cannot erase the data in the application program. After the vehicle-mounted controller receives the secret key, a second Flash erasing function in the vehicle-mounted controller is data which can be directly called to run. The vehicle-mounted controller can call a second Flash erasing function, and update information in a target application program based on the first vehicle-mounted information to be updated; and feeding back the update result of the application program to the upper computer. Compared with the prior art, in the process of updating the vehicle-mounted information each time, the vehicle-mounted controller does not need to receive the Flash erasing function of the Flash driver binary file sent by the upper computer, and can start the first Flash erasing function stored by the vehicle-mounted controller only according to the secret key from the upper computer. Because the resources occupied by the key are far smaller than the resources occupied by the Flash erasing function of the Flash driver binary file, the vehicle-mounted information updating method and device can improve the vehicle-mounted information updating efficiency.

Because the second vehicle-mounted information to be updated is obtained by splitting the first vehicle-mounted information to be updated, the data size of the second vehicle-mounted information to be updated is smaller than that of the first vehicle-mounted information to be updated. The upper computer sends at least one second vehicle-mounted information to be updated to the vehicle-mounted controller, so that the information transmission efficiency can be improved.
In one possible implementation, the first on-board information to be updated is verified; under the condition that the first vehicle-mounted information to be updated passes verification, first indication information is sent to an upper computer; the first indication information is used for indicating that the first vehicle-mounted information to be updated passes the verification of the vehicle-mounted controller; receiving a key from a host computer, comprising: and receiving a secret key sent by the upper computer in response to the first indication information.
According to the technical means, after receiving the first vehicle-mounted information to be updated, the vehicle-mounted controller verifies the first vehicle-mounted information to be updated.

In one possible implementation, it is checked whether the information in the target application is complete; under the condition that the information in the target application program is updated, the updating completion information is sent to the upper computer; and under the condition that the information in the target application program is not updated, ending the updating flow of the target application program, starting a first application program on the vehicle-mounted controller, and closing the application program when the first program updates the information in the target application program for the vehicle-mounted controller.
According to the technical means, the vehicle-mounted controller checks the update condition of the target application program, so that the time for ending the operation of the vehicle-mounted controller is determined according to the update condition of the target application program. After the target application completes updating, the functions of the vehicle-mounted controller are enriched by starting the first application.

According to the technical means, the upper computer sends first vehicle-mounted information to be updated to the vehicle-mounted controller and sends the secret key to the vehicle-mounted controller. The first Flash erasing function stored in the vehicle-mounted controller in advance is decrypted based on the secret key, so that a second Flash erasing function is obtained; the first Flash erase function is an encrypted function. In this way, the vehicle-mounted controller decrypts the second Flash erasing function which can be directly called to run based on the first Flash erasing function and the secret key which can not be directly called to run. That is, before the in-vehicle controller receives the key, the first Flash erasing function stored in advance in the in-vehicle controller is data that cannot be directly called for operation. Thus, even if the instruction pointer accidentally jumps to the entry of the first flash erase function, the first flash erase function cannot erase the data in the application program. After the vehicle-mounted controller receives the secret key, a second Flash erasing function in the vehicle-mounted controller is data which can be directly called to run. The vehicle-mounted controller can call a second Flash erasing function, and update information in a target application program based on the first vehicle-mounted information to be updated; and feeding back the update result of the application program to the upper computer. Compared with the prior art, in the process of updating the vehicle-mounted information each time, the vehicle-mounted controller does not need to receive the Flash erasing function of the Flash driver binary file sent by the upper computer, and can start the first Flash erasing function stored by the vehicle-mounted controller only according to the secret key from the upper computer.

With the rapid development of automobiles toward multifunction, in automobile development, testing, production and after-sales, it is often necessary to update on-board information to meet the diversity demands of users. However, in the process of updating the vehicle-mounted information, when the vehicle-mounted controller fails, the instruction pointer may accidentally jump to the entry of the flash erasing function in the controller, so that normal software data is erased, and the application of the vehicle-mounted application program is affected.
In the related art, in the process of updating the vehicle-mounted information, the upper computer issues a flash erasing function of the stored flash driver binary file to the processor. And the processor loads the flash erasing function into the RAM to realize the refreshing and updating of the vehicle-mounted information. Because the controller needs to download the Flash driver again when the vehicle-mounted information is updated each time, the vehicle-mounted information is updated in a complex way, and the waste of transmission flow is caused. Therefore, how to improve the efficiency of the vehicle information update is a technical problem that remains to be solved.
In view of the above problems, the present application proposes a vehicle-mounted information updating method, in which an upper computer sends first vehicle-mounted information to be updated to a vehicle-mounted controller, and sends a key to the vehicle-mounted controller. The first Flash erasing function stored in the vehicle-mounted controller in advance is decrypted based on the secret key, so that a second Flash erasing function is obtained; the first Flash erase function is an encrypted function. In this way, the vehicle-mounted controller decrypts the second Flash erasing function which can be directly called to run based on the first Flash erasing function and the secret key which can not be directly called to run. That is, before the in-vehicle controller receives the key, the first Flash erasing function stored in advance in the in-vehicle controller is data that cannot be directly called for operation. Thus, even if the instruction pointer accidentally jumps to the entry of the first flash erase function, the first flash erase function cannot erase the data in the application program. After the vehicle-mounted controller receives the secret key, a second Flash erasing function in the vehicle-mounted controller is data which can be directly called to run. The vehicle-mounted controller can call a second Flash erasing function, and update information in a target application program based on the first vehicle-mounted information to be updated; and feeding back the update result of the application program to the upper computer. Compared with the prior art, in the process of updating the vehicle-mounted information each time, the vehicle-mounted controller does not need to receive the Flash erasing function of the Flash driver binary file sent by the upper computer, and can start the first Flash erasing function stored by the vehicle-mounted controller only according to the secret key from the upper computer. Because the resources occupied by the key are far smaller than the resources occupied by the flash erasing function of the flash driver binary file, the vehicle-mounted information updating method and device can improve the vehicle-mounted information updating efficiency.
