Method for controlling the engagement force of the synchronizers of a dual clutch transmission |
摘要 |
<p>A method of controlling the engagement force of the synchronizers of a dual clutch transmission having a plurality of synchronizers to selectively engage and disengage various gears sets, and a plurality of shift actuators adapted to move the synchronizers. The method includes the steps of initiating a control routine to pressurize a shift actuator to move a synchronizer to a predetermined engagement position and determining the necessary level of force required to move the desired shift actuator to the predetermined engagement position such that the engagement movement is effected without excessive force. The method also includes the steps of determining the hydraulic pressure that corresponds to the determined level of force and varying the amount of available hydraulic line pressure delivered to the shift actuator such that the delivered pressure is the amount the corresponds to the determined level of force.</p> |
