自动变速器闭锁策略设计
Lockup Strategy Design of Automatic Transmission
摘要
Abstract
Power transfer characteristics of the torque converter in the locking are analyzed, and the dynamic model of torque converter is built up. Based on a comprehensive consideration of the output torque characteristic of engine, three-parameter dynamic lockup control rule is designed to promote automotive power performance. Optimization model of clutch oil pressure is also established,and based on ant colony algorithm, the variation of lockup clutch oil pressure is obtained. With the Matlab/Simulink/ Stateflow software, the lockup strategy is verified. A conclusion is drawn that the dynamic lockup control rule promotes vehicle power performance without impact or power interrupt in the locking.关键词
