A control device for a vehicle drive device having a speed change mechanism that attains a predetermined shift speed by engaging multiple engagement elements. The control device predicts an amount of heat generation and determines whether any jumping shift from the current shift speed to the shift speed that is the multiple shift speeds higher or lower than the current shift speed can be permitted or not between the current shift speed and the target shift speed, and if the jumping shift can be permitted, the control unit performs the jumping shift and controls the speed change mechanism so as to shift the shift speed from the current shift speed to the target shift speed.

A shift control apparatus includes a charging state detecting unit that detects a charging state, a shift lever that is held at a predetermined reference position, a limiting member that validates an operation of the shift lever located at the reference position when the limiting member is operated and a controller that validates a shift operation of the shift lever from the reference position to a predetermined operation position when the charging state of a vehicle is not detected and an operating amount of the limiting member is equal to or larger than a first changing condition amount and validates the operation of the shift lever from the reference position to the predetermined operation position when the charging state of the vehicle is detected and the operating amount of the limiting member is equal to or larger than a second changing condition amount.

A recreational vehicle is provided including a power source, such as an engine or an electric motor, and a transmission having a variable gear ratio. A sub-transmission coupled to an output of the transmission includes a plurality of selectable gear configurations including at least one of a forward gear, a neutral gear, a reverse gear, and a park gear. An electronic controller is operative to electronically control the gear configuration of the sub-transmission.

A transmission system configured to perform a gear change based on a shift operation by an operator is provided, which includes a power transmission system including a transmission and configured to transmit an engine driving force to wheels, a shift operation detecting module, and a transmission controlling module adapted to be executable of a manual rotation synchronizing mode having first and second steps. In the first step, when a first shift operation for changing the transmission to a lower-speed side is detected, the transmission controlling module sends a control signal to a connecting-and-disconnecting mechanism provided to the power transmission system to suspend the transmission of the driving force. In the second step, when a second shift operation is detected, the transmission controlling module sends a control signal to the connecting-and-disconnecting mechanism to resume the transmission of the driving force while the transmission is switched to the lower-speed side.
