Problems solved by technology

But its shortcomings are that the user's acceleration scene is not detailed enough, and the objective parameter of sound quality is extracted through data collection, ignoring the impact of driving operation on the user's psychology, thus changing the demand for power sound preferences

Abstract

The invention provides a multi-scene and multi-latitude user dynamic sound preference evaluation analysis method, which mainly researches the preference of a user for accelerated dynamic sound through a research mode, and establishes a set of dynamic sound preference five-dimensional evaluation method based on six acceleration scenes of the user. The user operation and psychological demand change can intuitively and finely analyze the preference of the user on the acceleration dynamic sound, thereby guiding the main engine plant to analyze the advantages and disadvantages of the dynamic sound design, determining the improvement direction of the dynamic sound, and improving the sound satisfaction degree of the user.

Description

technical field [0001] The invention belongs to the technical field of NVH (Noise, Vibration, Harshness, noise, vibration, acoustic vibration comfort) of vehicles, and specifically relates to the evaluation technology of acceleration dynamic sound. Background technique [0002] With the development of automobile technology and the upgrading of consumer demand, consumers no longer only pursue low noise in the car. How to improve the quality of acceleration sound in the car has become one of the key research and development contents of various OEMs. Researching consumers' preference for vehicle acceleration dynamic sound is the primary link to improve vehicle dynamic sound quality, and provides an important basis for the design and development of acceleration dynamic sound quality. [0003] At present, most automobile OEMs study the user's power sound preference method as follows: through the acquisition equipment that can reflect the human ear's auditory characteristics and p...
