Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a performance analysis system and method based on an automobile performance simulator. Background technique [0002] As an advanced model development tool, automobile performance simulator can provide a lot of help to the development of new models. Since the vehicle performance simulator is mainly used to research, test, analyze and reproduce the relationship and interaction between the vehicle and the driver and the vehicle and the external environment in the actual vehicle driving process, it relies on a refined dynamic model to complete the simulation. Scheme comparison and verification of vehicle braking, steering and suspension systems, etc. Therefore, the accuracy of the dynamic model in the vehicle performance simulator directly affects the feedback results of the vehicle performance simulator, thereby affecting the user's subjective evaluation results.

Problems solved by technology

[0004] However, the current problems are: 1. Since a large number of simulation conditions are required, and there are many different variables in each condition, it is necessary to continuously edit and draw the data in the process of viewing the simulation results, which is a waste of time. The testers spend a lot of time on preliminary work; 2. Due to the large amount of test data and the different formats of different test data, the process of comparing the simulation results with the test results is very heavy; 3. Due to the large number of parameters of the dynamic simulation model, the parameters There is uncertainty in the value, and there is a certain coupling between the parameters, so it takes many iterations to complete the manual adjustment of the parameters of the dynamic simulation model, which is time-consuming and laborious, and the effect cannot be optimal; 4 , The accuracy report of the dynamic simulation model needs to be manually edited, and the work of inserting pictures during the editing process is heavy, and there is no uniform standardization, and different testers have different levels of accuracy, resulting in the issuance of different quality accuracy reports
