发明名称 Method for shortening shifting time in a semi-automatic transmission
摘要 A method of shortening response time during a gear shifting operation process is applicable to a semi-automatic, electronically controlled transmission of motor vehicles, in particular utility vehicles, takes into account a driver's reaction time to reduce delay in clutch re-engagement. To initiate a gear-shifting operation in such a transmission, the driver actuates a shifting command emitter and at the same time disengages a clutch typically by depressing a clutch pedal. In response thereto, a newly selected gear is engaged in the transmission by an electronic system using outside force assistance, for example compressed fluid. The driver is informed via an acknowledgment device when the clutch can be properly engaged once more. In order to accelerate the entire gear shifting process, and concomitantly shorten the interruption of force flow attendant such shifting process, the acknowledgment device is actuated at a point in time prior to completion of transmission synchronization, when the electronic system has detected the beginning of the synchronization.
