Background

With the development of vehicle intellectualization and individuation, vehicle instrument software can be continuously updated in an iterative manner, and the trend of realizing online upgrade is inevitable.

When a vehicle instrument needs software update, the conventional method is to go to a 4S shop to perform software upgrade On the instrument through an On-Board diagnostics (OBD) of the whole vehicle. With The development of vehicle intelligence, The vehicle can realize online upgrade by means of an Over The Air (OTA) technology and a vehicle-mounted ethernet. However, sometimes the optimization and extension of the functions of the meter are only performed for certain vehicle models, which results in the need to adapt the functional configuration of the meter. These meter functional configurations are often stored in an Electrically Erasable Programmable Read Only Memory (EEPROM) or a Data flash memory (Data flash), and cannot be updated through software upgrade. The meter software code and configuration information storage locations are seen in fig. 1. As shown in fig. 1, the meter Code is stored in a Code memory (Code Flash), the configuration information Data is stored in Data Flash or an external EEPROM, and when the meter Code is upgraded, the Code Flash is only updated, so that when the configuration Data is rewritten, the user needs to drive to a 4S shop to reconfigure the configuration values through the diagnostic apparatus.

When the instrument software is upgraded on line, the newly added, changed or deleted instrument functions after upgrading are required to be reconfigured according to different vehicle types, so that the instrument function configuration data are required to be updated according to the software version, and the reconfigured instrument function data are required to be reset through a diagnostic instrument. Thus, the user still needs to drive to the 4S shop (automatic Sales service 4S, 4S shop), which limits the convenience and efficiency of OTA online upgrade.

Illustratively, taking the CAN network as an example, the data length of the functional configuration data exceeds the single-frame data length (i.e. 8 bytes) of the CAN network, the functional configuration data is unpacked and sent, and the vehicle instrument packages a plurality of groups of response information after receiving the functional configuration data to obtain complete functional configuration data. In this embodiment, the gateway 111 receives a plurality of pieces of response information sent by the server 120, and periodically sends the plurality of pieces of response information to the vehicle instrument 112 based on the data sending rule, the vehicle instrument 112 receives the plurality of pieces of response information, obtains target function configuration information by packaging and splicing the plurality of pieces of received response information, and configures an instrument software updating function according to the target function configuration information. And when the packaging and sending times of the response information reach a set value, stopping sending the response information.

As shown in fig. 3, after receiving the response message, the vehicle meter determines whether the response message is complete, and if not, the vehicle meter determines that the received response message is incomplete, stops receiving the response message, and restarts to send the response message in the next sending period; if yes, judging whether the number of times of packaging and sending the response information is equal to N, if yes, stopping sending the response information, and if not, continuing sending the response information in the next sending period. And N is the set packaging sending times. The gateway 111 sends the response message multiple times periodically, so that the network pressure can be reduced and the response message can be ensured to be correctly received by the vehicle meter 112. By splitting the function configuration data, each response message corresponds to part of the function configuration data, a plurality of response messages are sent to the vehicle instrument, and then the vehicle instrument 112 packages and splices the response messages to obtain complete function configuration data, thereby avoiding the software complexity increased by using a communication protocol.

Target function configuration data is obtained by splicing and packaging the plurality of response messages, and the integrity of the function configuration data is ensured.

On the basis of the foregoing embodiment, optionally, configuring the software update function according to the target function configuration information includes:

and comparing the target function configuration information with the current function configuration information, and configuring the software updating function according to the comparison result.

In this embodiment, the function configuration data of each function in the target function configuration information is compared with the function configuration data in the current function configuration information, and if the function configuration data in the target function configuration information of a certain function is different from the function configuration data in the current function configuration information, the corresponding function configuration data in the current function configuration information is updated; and if the function configuration data in the target function configuration information of a certain function is the same as the function configuration data in the current function configuration information, skipping the function configuration data, and continuously comparing the next function configuration data until the function configuration data in the target function configuration information of all the functions is compared with the function configuration data in the current function configuration information.

and analyzing the target function configuration information to obtain the identification information in the target function configuration information.

And verifying the identification information, and comparing the target function configuration information with the current function configuration information after the verification is passed.

The identification information is used for identifying the validity of the function configuration data in the target function configuration information, if the validity is valid, the target function configuration information is compared with the current function configuration information, and if the validity is invalid, the function configuration data of the corresponding part is ignored. Illustratively, such as Mask identification in the above example. In this embodiment, before the target function configuration information is compared with the current function configuration information, the target function configuration information is analyzed to obtain identification information in the target function configuration information, the identification information is verified to determine whether the corresponding function configuration data is valid, the valid function configuration data is compared with the corresponding function configuration data in the current function configuration information, if yes, the corresponding function configuration data is ignored, and if not, the function configuration data is updated. By checking the identification information, the configuration accuracy of the updating function of the instrument software is ensured, the comparison rate of the target function configuration information and the current function configuration information is improved, and the upgrading efficiency of the vehicle instrument is improved.
