Abstract
A gear engagement method for a hybrid vehicle includes detecting whether or not baulking occurs when a controller attempts to engage a target gear via a synchronizer. The gear engagement method also includes checking, by the controller, for a stationary state of the vehicle if the result of the detecting shows that there is baulking. The gear engagement method also includes engaging, by the controller via the synchronizer, a different gear that shares a same input shaft with the target gear if the result of the checking shows that the vehicle is in a stationary state. The gear engagement method also includes reattempting an engagement with the target gear after disengaging the different gear. The disengaging and the reattempting are performed by the controller via the synchronizer after the engaging.
Claims5
A gear engagement method for a hybrid vehicle, the gear engagement method comprising:
- detecting whether or not baulking occurs when a controller attempts to engage a target gear via a synchronizer;
- checking, by the controller, for a stationary state of a vehicle when the baulking is detected as a result of the detecting;
- engaging, by the controller via the synchronizer, a different gear when the vehicle is recognized to be in the stationary state as a result of the checking, the different gear sharing a same input shaft with the target gear;
- and
- reattempting, by the controller via the synchronizer after the engaging of the different gear, an engagement with the target gear after disengaging the different gear.
