A shift control arrangement in a gearbox comprising a first shift rod having a first end connectable to a first power means and second end connected to a first shift fork; a second shift rod having a first end connectable to a second power means and a second end connected to a second shift fork; a first set of grooves arranged in the first shift rod, a second set of grooves arranged in the second shift rod; and first and second lock pins arranged between the first and second shift rods, which together with the first and second set of grooves restricts or allows axial movement of the respective first and second shift rod.

A shift device includes a knob that is rotatable to select one of a plurality of gear modes of a transmission of a vehicle and a cam member that engages a portion of the knob in a rotation direction of the knob. The cam member rotates integrally with the knob only when engaged with the portion of the knob. The shift device further includes a drive source that rotates the cam member and a controller. The controller controls the drive source to rotate the knob to an operation position corresponding to a predetermined gear mode if a particular condition is satisfied. The controller decreases a voltage applied to the drive source when the cam member is rotated in at least a pre-engagement section until the cam member engages the portion of the knob from the voltage applied when the cam member is rotated in other sections.

An electric vehicle transmission method includes the steps of: detecting a gear-shift command; judging if the gear-shift command is in conflict, if it is in conflict, then it returns back to the step of detecting the gear-shift command while if it is not in conflict, then proceeds to the next step; proceeding to a synchronized position, a dispelling fork drives a synchronizer to make the synchronizer move from the original gear position to a synchronized position, and the dispelling fork does not move within a synchronized time; and proceeding to a target position, the dispelling fork drives the synchronizer again to make the synchronizer move to the target gear position.

In an electronic control unit, a traveling mode switching control unit switches a traveling mode from an N mode to a B mode when a shift lever is operated to a B operation position while the traveling mode is the N mode and the vehicle is traveling forward. Accordingly, during forward coast traveling in the N mode, the traveling mode is switched from the N mode to the B mode by an operation in one direction of the shift lever to a B operation position without requiring operations in two directions of the shift lever to a D operation position. Accordingly, it is possible to prevent a driver from experiencing difficulty in operating the shift lever at the time of switching the traveling mode from the N mode to the B mode during forward coast traveling in the N mode.

A controller includes: an automatic shifting control section that carries out automatic shifting control in which a shifting actuator is driven in response to a predetermined automatic shifting command; and an interference prevention control section that controls the automatic shifting control section so as to prohibit simultaneous occurrence of a manual shifting process induced by operation of a shifting operation member and an automatic shifting process induced by the shifting actuator.
