no. 1 example

[0024] figure 1 The flow chart of the OBD upgrade method provided by the first embodiment of the present invention is composed of figure 1 It can be seen that the OBD upgrade method provided in this embodiment includes:

[0025] S101: The modem obtains the device upgrade package of the vehicle automatic diagnosis system device;

[0026] S102: The modem splits the device upgrade package into a first software package for upgrading the modem and a second software package for upgrading the microcontroller;

[0027] S103: the modem pushes the second software package to the microcontroller;

[0028] S104: The microcontroller upgrades the microcontroller according to the second software package.

[0029] This embodiment provides a kind of OBD upgrade method, this method splits and obtains the software package of MCU when Modem receives data package, and pushes to MCU, makes MCU can carry out MCU upgrade directly according to software package, no longer needs Modem upgrade Later, ...

[0062] figure 2 It is a schematic structural diagram of the OBD device provided by the second embodiment of the present invention, which is represented by figure 2 It can be seen that the OBD device provided in this embodiment includes: a modem 1 and a microcontroller 2, wherein,

[0063] The modem 1 is used to obtain the equipment upgrade package of the on-board automatic diagnosis system equipment, split the equipment upgrade package into a first software package for upgrading the modem, and a second software package for upgrading the microcontroller, and push the second software package to microcontroller 2;

[0064] Microcontroller 2 is used for microcontroller upgrade according to the second software package.

[0065] In some embodiments, before the modem 1 in the above-mentioned embodiment pushes the second software package to the microcontroller 2, it is also used to judge whether the modem needs to be upgraded according to the first software package, and if an upgr...

[0070] The present invention will be further explained in combination with specific application scenarios.

[0071] The existing OBD software versions are all packaged in the Modem. The Modem must be upgraded first. After the Modem upgrade is completed, the MCU upgrade is triggered by issuing an instruction. The device can only be upgraded after the car is ignited, which will affect the user experience; the BOOT pin of the main control MCU Linked to the Modem, the MCU can be controlled through the Modem as the main control; the software version update must first upgrade the Modem version, and then upgrade the MCU, even if the Modem side software has no content to update, only the MCU side software version needs to be updated and the Modem upgrade process must be started first , and then trigger the version update on the MCU side after the upgrade on the Modem side is completed.

[0072] For above-mentioned problem, present embodiment provides new OBD equipment upgrading method...

Abstract

The embodiment of the present invention provides a vehicle-mounted automatic diagnosis system device and its upgrading method; the method includes: the modem obtains the device upgrade package of the vehicle-mounted automatic diagnosis system device; A software package, and a second software package used to upgrade the microcontroller, and push the second software package to the microcontroller; the microcontroller is upgraded according to the second software package. The present invention splits and obtains the software package of the MCU when the Modem receives the data package, and pushes it to the MCU, so that the MCU can directly upgrade the MCU according to the software package, and no longer needs to trigger the MCU upgrade after the Modem upgrade, realizing the modem upgrade and The decoupling of MCU upgrade avoids invalid upgrade of Modem.

Description

technical field [0001] The invention relates to the field of on-vehicle automatic diagnosis system equipment, in particular to an on-vehicle automatic diagnosis system equipment and an upgrading method thereof. Background technique [0002] With the rapid development of the automobile and Internet industries, various new types of OBD (On-Board Diagnostics, on-board automatic diagnostic system equipment) and other on-board equipment are constantly appearing in the market. At the same time, the functional requirements of on-board equipment are also constantly updated. It is becoming more and more intelligent. When updating the device, the software version is packaged in the Modem. The Modem must be upgraded first. After the Modem upgrade is completed, the MCU upgrade is triggered by issuing an instruction. [0003] Since the equipment update is often carried out for the microcontroller MCU during use, the Modem does not need to be upgraded in fact. Therefore, the existing OBD...
