Study On The Evaluation Method Of Vehicle Drivability Based On Subjective And Objective Data

With the development of society and the continuous improvement of economic level,consumers have put forward higher requirements for vehicle economy,power and driving,especially driving,which is directly related to the evaluation of vehicle performance by drivers and passengers.It also affects the driving experience of drivers and passengers.Drivability is the response of the vehicle to the driver’s throttle and shifting.It is manifested in a series of accelerated response,smoothness,stability,and also in the start and idle conditions,driving is the key to customer evaluation of the vehicle.index.Driving is also an important indicator to measure the development of the vehicle powertrain system.It is closely related to the power,economy and comfort of the car.It is an important manifestation of the inherent quality of the car.At present,relevant scientific research institutes and various research institutions have done a lot of research and analysis on driving evaluation.However,the research on the method of driving evaluation based on user feedback data and data collected by vehicles is still not very in-depth and detailed.From subjective evaluation to objective evaluation based on user feedback data and vehicle acquisition data,it can be convenient,fast and direct to evaluate the driving performance of the whole vehicle,which is of great significance to improve the evaluation level of the driving performance of the whole vehicle.The improvement of driving ability is the most important task of locomotive matching in major vehicle enterprises.This paper mainly excavates the driving problem based on the user feedback data.By analyzing and researching the evaluation factors of vehicle driving ability,it puts forward the methods to improve and improve vehicle driving ability.Based on the analysis of the evaluation methods of vehicle driving ability,it puts forward the objective evaluation of vehicle driving ability through vehicle data acquisition system.The test method is applied to evaluate the driving performance of DCT vehicles objectively.Through the study of subjective and objective evaluation methods and optimization methods of driving performance,the methods and ideas of improving driving performance and solving problems based on subjective and objective data are put forward.
