| Abstract: | Based on the engine map, investigated in this paper are how to determine the transmisson ratios of the driveline and to achieve their optimization with considerations of vehicle practical running conditions. Some examples of transmission ratio optimizations are given and the results well coincide with the gear ratios of both domestic and foreign advanced automotive gearboxes. |
