Optimized in-loop simulation test method for automobile auxiliary driving controller

Abstract

The invention relates to an optimized in-loop simulation test method for an automobile auxiliary driving controller. The method comprises the steps of characteristic data acquisition, scene model simulation, detection characteristic simulation and driving control data processing. In the characteristic data acquisition stage, detection characteristic data and execution characteristic data are acquired, and a real vehicle characteristic database is established. In the scene model simulation stage, simulation software such as a sensor model, a vehicle model and a driving environment model is usedfor simulating a real vehicle driving scene model. In the detection characteristic simulation stage, detection characteristic data such as perception detection time lag, lane line recognition errors,obstacle target recognition errors and perception part fault parameters are subjected to simulation analysis. In the driving control data processing stage, auxiliary driving controller data processing or automatic driving controller data processing is carried out; and the execution component response time lag, the execution component response error and the execution component fault parameter areanalyzed and simulated. The method has the advantages of convenience in detection, reliable data, high automation degree and wide application range.
