Embodiment 1

[0037] Such as figure 1As shown, a verification system for OTA upgrade reliability, including a line diagnostic tool, a terminal, and a cloud server, the line diagnostic tool for line-off-auxiliary verification, is used to fail on brushing and When the software fails, the software is brushed on the server; when the upgrade is successful or the upgrade failed, the software did not have a fault, and the time diagnostic information sent by the vehicle to the line diagnostic tool. The cloud server is used to send a test task, a formal task, and a test task for test package verification. The official task A and B are alternately verified; after receiving the task, feedback Give the server.

[0038] Such as figure 2 As shown, a flow chart of the verification method of the present invention;

[0039] A verification method for OTA upgrade reliability, including alternating verification, test package verification, and line assistance; the interplacement verification is used to verify that ...

Embodiment 2

[0041] A verification method for OTA upgrade reliability, including the following steps:

[0042] (1) After the start of the process, the test will produce the A version of the upgrade software into a test upgrade package A, then upload the test upgrade package to the server; use the test upgrade package A deployment task on the cloud server, then the test vehicle is connected to the test upgrade Task A, this time, the test is selected whether it is upgraded; if you choose to upgrade, then the car is upgraded; if you do not upgrade, you will continue to send an upgrade application to the car at a number of times; before sending the application, you must first judge before sending the application Whether it is timeout, each task is made by his timer, if more than the timer time, then no longer sends an upgrade application, if the upgrade requires the test to re-deploy the upgrade task; if there is no exceeding the timer, continue The test person judges whether or not;

Abstract

The invention discloses a verification system and method for OTA reliability, and belongs to the technical field of automotive electronics, and the method comprises alternate verification, test pack verification and offline auxiliary verification. The alternate verification is used for verifying the reliability of whether the software can be subjected to remote OTA or not in an actual upgrading environment; the test pack verification is used for providing trial and error links for alternate verification and reducing the pressure of software development; the offline auxiliary verification is to perform simple version verification and function verification on the flashed software through a diagnostic instrument. The test pack verifies that software functions are detected in advance, problems are found in time, development pressure can be reduced to a certain extent, development cost is reduced, and pressure of a server is reduced; multidimensional detection is carried out on software through offline auxiliary verification, the accuracy of cloud server information is verified, and the whole upgrading process is clearer and more controllable; alternating verification can verify functions of software on the aspect of OTA in an upgrading environment in advance, problems can be found in advance, cost is saved, and technical risks are avoided.

Description

Technical field [0001] The present invention belongs to the field of automotive electronics, and is specifically related to verification systems and methods for OTA reliability. Background technique [0002] In the automotive industry, artificial intelligence is an increasing topic. Especially in today's era, the car gradually presents trends in the control and definition of software rather than traditional mechanical components. In the past, if a car wants to upgrade the software, then it must go to the corresponding service station to connect the system or computer to the computer. Now, OTA solves the dependency problem that the automotive software upgrade must be on site. And, safe, timely and simple OTA software upgrade methods are very necessary to each car. OTA's mobile phone and car upgrade method are different, and the OTA upgrade relative to the phone is more complicated and strict, and incorrect software updates is possible to affect the lives of the driver. In view of ...
