Research on Large-Scale Vehicle Chassis Dynamometer (LVCD) Testing Software System

The LVCD is an equipment for testing vehicle oil economy, power performance, engine exhaust emission appraisal and analysis, reliability and some specific items of vehicle power-train. In order to make great use of the LVCD and to assure the testing correctness, reliability, fastness and convenience, a test and control software system used in LVCD was investigated & manufactured based on national vehicle testing standard in this paper, and was validated by real vehicle testing. This software system made a solid foundation for effectively using LVCD.
