automatic mechanical transmission start process clutches control strategy
In order to enhance the effect of the clutch auto control for vehicles with automatic mechanical transmission(AMT),the traditional clutch control strategies are optimized.After analyzing the force change of the power train and the data of experimentation,the problem that the traditional clutch control strategy can not start vehicles smoothly and swiftly at the same time is pointed out.To solve the problem,the phases of start process are increased.The clutch sliding stage is divided into the front stage and the back stage.The control strategy of the back stage is optimized.The clutch is disengaged in the second clutch sliding stage to reduce the impact of the synchronization and make the vehicle start smoothly and swiftly.The method is validated through the vehicle test.
