Testing and analysis of automotive gearshift performance based on gear shift analysis

Abstract

With the increasing demand for vehicle handling comfort in the market, the development of gear shifting performance test systems for automobile transmission has become one of the keys to improving the competitiveness of automobile products. In order to continuously improve the shifting quality of the automobile gearshift control, this research focuses on the study of shifting quality, uses GSA (gear shift analysis) test technology to test and verify the shifting performance of a domestic automobile gearbox, establishes the subjective and objective evaluation criteria for the shifting performance of automobile gearbox, provides a reliable theoretical basis for product optimization design and shifting performance evaluation, and formulates shifting control pertinently. Strategies and optimization measures to ensure that the power, ride, and transmission of the whole vehicle system meet the technical requirements and can shift quickly and smoothly. Not only does this allows to reduce the driver's fatigue strength, but also increases the comfort of the whole shifting process, so as to provide direction to improve the quality of the vehicle's shifting performance and effectively reduce the impact on the driver's health.

An empirical study on new-energy vehicle users’ preferences of in-vehicle interaction input methods

“…Additionally, experienced drivers exhibit more confidence in operating mechanical gear shift levers compared to novice drivers. Shen et al had the same argument, and they highlighted the potential benefits of button shifting for enhancing vehicle handling comfort and optimizing gear shifting performance for broader market accessibility [ 68 ].…”

Development of a Real-Time Tractor Model for Gear Shift Performance Verification

“…Although many studies have been conducted to produce and validate a real-time simulation model according to the specific purpose of the vehicle, no studies have been conducted on models driven in real time while finely simulating the mechanical systems involved in gear shift performance. Improving gear shift performance is directly related to the ride comfort of the vehicle, making it one of the key factors in vehicle development [20][21][22]. The gear shift performance varies depending on the synchronization time of speed and torque generated through the clutch and synchronizer during the gear shift process [23][24][25].…”
