A Road Load Data Processing Method for Transmission Durability Optimization Development

With increasing pressure from environment problem for reduction in CO2 emissions and stricter fuel targets from road vehicles, new transmission technologies are gaining more attention in different main market. To get suitable road load data for transmission durability development is becoming increasingly important and can shorten the development time of new transmission.

This paper presents the procedure and methods of road load data development for durability design of transmission product and optimization based on the real road data measurement, statistical characteristics evaluation and fatigue damage equivalency. Apply this road load data method procedure on 3 type of vehicle which represent conventional vehicle, BEV and HEV. Through comparison with conventional vehicle transmission, BEV transmission and HEV transmission real road load measurement and duty cycle will show some connection and difference that can be reference for the reference development of other forms of transmission duty.
