CONTROL STRATEGY AND SYSTEM ANALYSIS BASED ON THE VEHICLE ENGINE EMISSION AND GEARBOX MATCHING

摘要

The vehicle emission is one of the main pollution sources in city in the world. It is the main object generally to control the engine and transmission matching in order to improving the power and economic benefit. But the lower fuel consumption of vehicles is not always attained the better emission and lower pollution. The thesis discusses and analyses the relation between the vehicle emission and economic benefit according to the vehicle emission characteristic; and studies and researches the engine and transmission matching that influence the vehicle emission and economic benefit. And the paper indicates the control stratagem of the engine and transmission matching base on the vehicle emission and simulation. This control method can realize the better control for engine and transmission in lower fuel consumption and better emission.
