Hardware-in-the-loop test system for vehicle FOTA function automatic verification

Abstract

A hardware-in-the-loop test system for automatic verification of a vehicle FOTA function comprises a TSP background, a vehicle-mounted device, a hardware-in-the-loop device and a test software. The TSP background refers to an FOTA background, and can be connected with the FOTA background through test software to perform upgrade task configuration and upgrade information query; the vehicle-mounted device comprises a T-BOX, an entertainment system and other vehicle-mounted ECUs, the T-BOX serves as an upgrading master to be in interactive connection with the TSP background, the entertainment system and the other vehicle-mounted ECUs, current software information and software upgrading information are obtained, and software upgrading is carried out; the hardware-in-the-loop equipment supports real-time operation of a controlled object model, and can simulate simulation and acquisition of vehicle state hard wire IO, bus messages, power supply logic and process signals required by the to-be-tested electronic control unit; and the test software is responsible for flow control of the test system, interacts with the TSP background, the vehicle-mounted equipment and the hardware-in-loop equipment, and realizes test verification of an FOTA data link, functions and stability. Under the continuous unattended condition for a week, hardware can be automatically controlled, model parameters can be read and changed, a TSP background can be accessed, and software function logic testing can be automatically completed.

Description

technical field [0001] The invention belongs to the technical field of on-vehicle testing, and in particular relates to a hardware-in-the-loop testing system for automatic verification of vehicle FOTA functions. Background technique [0002] At present, the widely used test methods require a large number of staff, the test cycle is long, and the test efficiency is low. Moreover, the number of tests that can be performed during the development cycle is limited, and stress testing cannot be performed well. [0003] The domestic method of automated testing by simulating the client is somewhat different from the real working conditions, and cannot fully restore the real working conditions, and the reliability of the test results is not high. The automated testing equipment has not been fully automated, and the staff still needs to intervene during the testing process, so it is impossible to carry out long-term stress testing without being on duty.

Problems solved by technology

[0002] At present, the widely used test methods require a large number of staff, the test cycle is long, and the test efficiency is low.

And the number of tests that can be carried out during the development cycle is limited, so it is not possible to carry out stress testing well

[0003] The domestic method of automated testing by simulating the client is somewhat different from the real working conditions. It cannot completely restore the real working conditions, and the reliability of the test results is not high.

Automated testing equipment is not fully automated, and staff intervention is still required during the testing process, making it impossible to conduct long-term stress testing without supervision
