Method and system for reinjecting real vehicle data into Simulink model

Abstract

The invention discloses a method and system for reinjecting real vehicle data into a Simulink model, and the method comprises the following steps: 1), extracting reinjected data; the reinjection data extraction refers to extracting effective data from problem data in a real vehicle, and converting the effective data into a data format timeseries which can be directly injected into the Simlink model; 2) constructing a reinjection model; the reinjection model construction is that a reinjection Simulink model matched with a problem model on a real vehicle is copied on a computer to obtain a copied model, and an interface of the copied model is transformed, so that reinjection data can be reinjected into the copied model through the transformed interface; and 3) running the extracted reinjection data on the reinjection model to realize real vehicle data reinjection The method can automatically complete the data reinjection work, shortens the troubleshooting period, and improves the working efficiency.

Description

technical field [0001] The invention relates to the technical improvement of data re-injection, and more specifically relates to a method and system for real-vehicle data re-injection into a Simulink model, which belongs to the field of vehicle technology. Background technique [0002] With the increasing development of the national economy, people's demand for cars has gradually shifted from the hard experience brought by hardware to the soft experience brought by software, thus ushering in the vigorous development of vehicle software. With the increase in the complexity of software functions, complex algorithms and strategies have been introduced into many functional areas, such as autonomous driving, intelligent vehicle control, intelligent chassis, and so on. [0003] In the development stage of the vehicle, there are a large number of real vehicle road tests, and there are also a large number of test problems. When the complexity of the software is high, even the functi...

Problems solved by technology

[0005] However, due to the essential difference between the actual vehicle data acquisition toolchain and the development toolchain application scenarios, it is impossible to directly inject data back into the Simulink model, and usually requires more conversion steps, and these processes are currently mostly completed by humans, and relevant personnel Need to have certain professional technical requirements

At the same time, as the volume of data increases, the process of data re-injection will become more cumbersome and lengthy
