We primary introduced the principle and approach of desktop calibration of AT based on the condition of coupling characteristics between engine and torque converter and obtained right point exactly. It is shown to agree with experimental measurements reasonably well. It was used in different applications abroad based on AT technology and achieved a good performance of the vehicle compared with traditional AT technology which primary focuses on the drivability, performance and fuel consumption.展开更多

Since only one task space is provided for performing such tasks in the Windows operating system,a number of computer users feel inconvenience.In this paper,we suggest a 3D Virtual Desktop System which can show a process of switching task spaces in 3D motion using DirectX. Our system aims to make up for the weak points in the Windows operating system,and to provide a computer user with more spaces for performing several tasks as well as the intuitive UI(User Interface),such as Compiz of Linux.展开更多

文摘Desktop calibration of automatic transmission(AT) is a method which can reduce cost, enhance efficiency and shorten the development periods of a vehicle effectively. We primary introduced the principle and approach of desktop calibration of AT based on the condition of coupling characteristics between engine and torque converter and obtained right point exactly. It is shown to agree with experimental measurements reasonably well. It was used in different applications abroad based on AT technology and achieved a good performance of the vehicle compared with traditional AT technology which primary focuses on the drivability, performance and fuel consumption.
