Problems solved by technology

But there are many shortcomings in this: first, even for experienced and skilled drivers, it is impossible to ensure that the input to the tested car is completely consistent in multiple experiments, and the evaluation results of such tests are not objective; secondly, when the test speed is high There is a certain danger to the driver when the road conditions are bad or when the road environment is bad; finally, when the steering system parameters do not have a general range, a large number of real car experiments will consume too much money and energy; at the same time, the trial production of the steering system prototype will also wasted a lot of money

Abstract

The invention aims to provide a system and a method for assisting in designing parameters of a steering system of a vehicle on the basis of a driver model. The method is mainly applied to an initial steering system designing stage, is implemented by the aid of a virtual simulation platform and is used for testing the parameters of an initially designed steering system under the consideration of driving characteristics of a driver. The system for testing the parameters of the steering system of the vehicle comprises the driver model, a vehicle steering system module, a vehicle module, a virtual testing road environment module and an information storage module. The system and the method have the advantages that a driving procedure implemented by a person is simulated in an integral testing procedure, and the parameters of the steering system are changed, so that state response of the vehicle can be acquired; the state response is analyzed, so that the parameters of the steering system can be optimized, and the performance of the steering system can effectively conform to the driving characteristics of the person.

Description

1. Technical field [0001] The invention relates to testing and evaluating the parameters of the steering system of the vehicle at the early stage of vehicle design in order to achieve the optimal design of the parameters of the auxiliary steering system, and belongs to the field of vehicle engineering. 2. Background technology [0002] The birth of automobiles has improved people's traffic and transportation efficiency, enriched people's lives, and changed people's travel methods. With the rapid economic growth and the rapid development of vehicle production technology, the holdings of vehicles continue to increase.
