Method for testing vehicular electric control system based on real vehicle running state dynamic real-time playback

Abstract

The invention discloses a method for testing a vehicular electric control system based on real vehicle running state dynamic real-time playback. The system comprises a data formatting processing module, a real vehicle running state dynamic real-time playback module, a testing task module and a high-level driving I / O (Input / Output) interface module communicating with the electric control system. The data formatting processing module is used for formatting vehicle road-test test data as an input and sending the formatted road-test test data to the real vehicle running state dynamic real-time playback module through a data transmission interface. The testing task module is set in a single test state or a cycle test state according to test requirements. The high-level driving I / O interface module is used for interacting real-time data with the vehicular electric control system based on a data communication interface card, transmitting the real vehicle running state data to a lower computer control system of the electric control system and building a true real vehicle running environment to the lower computer control system. According to the method disclosed by the invention, the real vehicle test number is effectively reduced; the cost is saved; and the development cycle of the electric control system is greatly shortened.

Description

technical field [0001] The invention relates to a testing method for a vehicle electronic control system, in particular to a testing method for a vehicle electronic control system based on dynamic real-time playback of the driving state of a real vehicle. Background technique [0002] In the development process of the vehicle electronic control system, it is necessary to provide a test environment and test method to verify its various functions and performances, so as to evaluate whether the developed electronic control system meets the expected design requirements.

The existing electronic control system function test environment and test method are mainly realized based on the hardware-in-the-loop simulation system, that is, the test environment of the electronic control system function is provided through the established vehicle simulation model. Due to the complexity and accuracy of the established simulation model Performance and other aspects are limited to a certain extent, so there is a big difference between the electronic control system function test based on hardware-in-the-loop simulation and the actual vehicle test
