Therefore, a firmware upgrading method is needed to solve the problems that the vehicle-mounted system cannot automatically upgrade the firmware, so that labor is consumed, upgrading accuracy is low, and production efficiency is affected.
As shown in fig. 1, the firmware upgrading method according to the embodiment of the present disclosure includes the following steps:
and step S101, detecting a unit to be upgraded in the vehicle-mounted system.
During specific implementation, the detection end is connected with the vehicle-mounted system, the unit model in the vehicle-mounted system is obtained through detection, and the unit to be upgraded is determined.
And S102, acquiring first upgrading data corresponding to the vehicle-mounted system according to the unit to be upgraded.
In specific implementation, first upgrading data for upgrading the vehicle-mounted system is obtained through a server or other ways, the first upgrading data comprises an upgrading file and an upgrading list, the upgrading list is used for determining a unit to be upgraded, and the upgrading file is used for upgrading the unit to be upgraded.
And step S103, sending the first upgrading data and the first upgrading instruction to the vehicle-mounted system.
In specific implementation, the acquired first upgrading data is sent to a designated position of the vehicle-mounted system, usually to a position for storing an upgrading file in an OTA upgrading process of the vehicle-mounted system, and an upgrading instruction is sent to the vehicle-mounted system at the same time, wherein the upgrading instruction is used for instructing the vehicle-mounted system to upgrade the firmware of each unit to be upgraded based on the first upgrading data. The vehicle-mounted system can skip the upgrade judgment condition and directly upgrade the firmware. After the upgrade result information is sent, the upgrade result information can inform whether the firmware upgrade succeeds or not, if the upgrade fails, second upgrade data is determined according to the upgrade result information and the first upgrade data, and the second upgrade data is sent to the vehicle-mounted system so that the vehicle-mounted system can be upgraded again.
As shown in fig. 2, the automatic firmware upgrade method according to the embodiment of the present disclosure includes the following steps:
step S201, receiving first upgrade data and a first upgrade instruction sent by the detection end.
In specific implementation, the first upgrade data includes an upgrade file and an upgrade list, the upgrade list is used for determining a unit to be upgraded, and the upgrade file is used for upgrading the unit to be upgraded. Of course, second upgrade data and a second upgrade instruction sent by the detection end may also be detected, where the second upgrade data is upgrade data corresponding to a unit to be upgraded that fails to be upgraded in the first upgrade data.
Step S202, firmware upgrading is carried out on each unit to be upgraded according to the first upgrading instruction and the first upgrading data.
In specific implementation, after a first upgrade instruction is received, an upgrade file corresponding to an element to be upgraded and an original element to be upgraded is determined through an upgrade list in first upgrade data, and firmware upgrade is performed on the element to be upgraded through the determined upgrade file. After upgrading, upgrading result information can be generated according to the upgrading result, and the upgrading result information is sent to the detection end.
Specifically, when updating result information is generated, if firmware updating fails, an updating failure list is added into the updating result information, and the updating failure list is used for enabling the detection end to determine a unit with updating failure; and if the firmware is successfully upgraded, informing the detection end of successful upgrade through the upgrade result information.
If the second upgrade instruction and the second upgrade data are received in step S201, firmware upgrade is performed on the unit to be upgraded in the upgrade failure list according to the second upgrade instruction and the second upgrade data, so that the unit to be upgraded that fails to be upgraded is upgraded.
As shown in fig. 3, the firmware upgrading method in the embodiment of the present invention is described in detail with reference to a detection end and a vehicle-mounted system, where the detection end is EOL detection equipment, and the vehicle-mounted system is an HMI.

Step S301, detecting a unit to be upgraded in the vehicle-mounted system.
During specific implementation, the detection end is connected with the vehicle-mounted system, the unit model in the vehicle-mounted system is obtained through detection, and the unit to be upgraded is determined.
Step S302, first upgrading data corresponding to the vehicle-mounted system is obtained according to the unit to be upgraded.
In specific implementation, the first upgrade data for upgrading the vehicle-mounted system is obtained through a server or other ways, the upgrade package of the EOL upgrade cannot be obtained from the OTA background, and because the whole vehicle vin code and the current whole vehicle firmware version number are not available, the upgrade files can only be obtained through the server of the EOL, and the input of the upgrade files comes from the upstream of a supplier DRE and the like. The first upgrading data comprises an upgrading file package and an upgrading list, wherein the upgrading file package is usually in a zip compressed file package format and comprises a plurality of upgrading files, and the upgrading list can be a manifest json file and is used for determining a unit to be upgraded in the vehicle-mounted system and upgrading files corresponding to the unit to be upgraded.
Step S303, the first upgrading data and the first upgrading instruction are sent to the vehicle-mounted system.
In specific implementation, the acquired first upgrading data and the first upgrading instruction are sent to a specified position of the vehicle-mounted system, and are usually sent to a position used for storing an upgrading file in the OTA upgrading process of the vehicle-mounted system, and the first upgrading instruction is used for indicating the vehicle-mounted system to upgrade the firmware based on the first upgrading data. Therefore, the vehicle-mounted system can skip the upgrading judgment condition and directly upgrade the firmware.
Step S304, receiving the first upgrade data and the first upgrade instruction sent by the detection terminal.
In specific implementation, after a first upgrade instruction is received, the element to be upgraded (namely the ECU to be upgraded in the HMI) and the upgrade file corresponding to the original element to be upgraded are determined through the upgrade list in the first upgrade data, and specific operation is to analyze the manifest.
Step S305, upgrading the firmware of each unit to be upgraded according to the first upgrading instruction and the first upgrading data.
In specific implementation, the firmware upgrading is performed on the element to be upgraded determined in the step by using the upgrading file determined in the step, namely, the ECU is sequentially upgraded according to the upgrading sequence configured in manifest.
And S306, generating upgrading result information according to the upgrading result, and sending the upgrading result information to the detection end.
Specifically, when updating result information is generated, if firmware updating fails, an updating failure list is added into the updating result information, and the updating failure list is used for enabling the detection end to determine a unit with updating failure; and if the firmware is successfully upgraded, informing the detection end of successful upgrade through the upgrade result information.
Step S307, the detection end receives the upgrading result information and determines the upgrading result, if the upgrading is successful, the firmware upgrading process is ended, and if the upgrading is failed, the step S308 is carried out.
And step S308, determining second upgrading data according to the upgrading result information and the first upgrading data, and sending the second upgrading data and a second upgrading instruction to the vehicle-mounted system so as to upgrade the vehicle-mounted system again.
