Abstract
A system and method of controlling a transmission having a synchro-mesh type shifting mechanism are provided. The method includes disengaging a sleeve of a synchronizer from a first clutch gear to engage the sleeve with the second clutch gear. A speed of the second clutch gear is synchronized with a speed of the sleeve. Engagement of the sleeve with the second clutch gear is the completed together with the synchronization. Therefore, the length of torque interruption is reduced and smoother shifting is achieved.
Claims11
A method of controlling a transmission by an electric controller, which includes a first speed gear and a second speed gear for implementing shifting for two different speeds at both sides from a synchronizer, the method comprising:
- moving, by the controller, a sleeve of the synchronizer to disengage the sleeve from a first clutch gear directly connected to the first speed gear and engage the sleeve with a second clutch gear directly connected to the second speed gear;
- synchronizing, by the controller, a speed of the second clutch gear with a speed of the sleeve with a motor connected to an input shaft while a synchronizer ring slides on a friction cone of the second clutch gear by the movement of the sleeve;
- and
- completing engagement, by the controller, of the sleeve with the second clutch gear, together with the synchronization of the speeds of the second clutch gear and the sleeve by the synchronizing.
A method of controlling a transmission, comprising:
- disengaging, by a controller, a sleeve of a synchronizer from a first clutch gear to engage the sleeve with the second clutch gear;
- synchronizing, by the controller, a speed of the second clutch gear with a speed of the sleeve;
- and
- completing engagement, by the controller, of the sleeve with the second clutch gear together with the synchronization.
A system of controlling a transmission which includes a first speed gear and a second speed gear for implementing shifting for two different speeds at both sides from a synchronizer, the system comprising:
- a memory configured to store program instructions;
- and
- a processor configured to execute the program instructions, the program instructions when executed configured to:
- move a sleeve of the synchronizer to disengage the sleeve from a first clutch gear directly connected to the first speed gear and engage the sleeve with a second clutch gear directly connected to the second speed gear;
- synchronize a speed of the second clutch gear with a speed of the sleeve with a motor connected to an input shaft while a synchronizer ring slides on a friction cone of the second clutch gear by the movement of the sleeve;
- and
- complete engagement of the sleeve with the second clutch gear, together with the synchronization of the speeds of the second clutch gear and the sleeve by the synchronizing.
