Embodiment Construction

[0046] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the embodiments and accompanying drawings.

[0047] In the current test method of vehicle FOTA function, the download of vehicle information software, the transmission of vehicle control software and software installation are all time-consuming. The manual test load is heavy and the efficiency is low, and the stress test is hundreds of times. , 1,000 times level, the specific number of times refers to the reliability definition specification, so the 24-hour uninterrupted test of multiple benches is a necessary strategy to shorten the test cycle. In order to improve the test efficiency and accuracy, it is very useful to develop an automated test system and method necessary.

[0048] Therefore, the present invention proposes a vehicle FOTA function automatic testing method and system, in the fi...

Abstract

The invention relates to a vehicle FOTA function automation test method and system, and the method comprises the following steps: supplying constant electricity to a to-be-tested system, and initializing a simulation power domain related signal; clicking a downloading button; judging and detecting whether a downloading button appears or not or whether the downloading progress bar is updated or not, and if so, clicking the button; waiting for transmission of the vehicle control software package, and automatically triggering a message record; detecting the installation button, and simulating clicking of the installation button; judging whether an installation button occurs or a data transmission progress bar is updated or not; clicking a button, recording flag bit counting, sequentially installing the vehicle control package and the vehicle-mounted package to a to-be-tested system, completing local access to the cloud platform, loading and unloading the next installation package, and automatically triggering message recording; after message feedback is read, extracting a software version character string after installation; judging whether the installed software version is consistent with the expected version or not; judging the count of the flag bit, and checking whether the downloading and installing times reach a set value or not; and ending the test and outputting a test report. The method and system are high in testing efficiency and low in cost.

Description

technical field [0001] The invention relates to the technical field of automated testing of automotive electronic and electrical control units, in particular to a vehicle FOTA function automated testing method and system. Background technique [0002] As the car becomes more and more intelligent, the software of the car controller becomes more and more complex, and the development cycle is shorter. The loopholes in the software and the continuous iteration of functions require the controller software on the car to be upgraded. Using FOTA (FirmwareOver—The—Air) technology, download new software from the cloud through the wireless network to upgrade the vehicle ECU software to improve user experience and repair software vulnerabilities. The in-vehicle infotainment system is the only channel for in-vehicle information software packages and vehicle control software packages to obtain data from the cloud server of the Internet of Vehicles. Among them, the iterative upgrade applic...
