A power generation system includes a continuously variable transmission, a power generator, a transmission driving device, an output-side speed detector, and electric power load device, and a controller. The electric power load calculation device detects current values and current values of respective phases of three-phase alternating current generated by the power generator, calculates electric power load of the power generator based on the detected values, and executes filtering by attenuating a higher harmonic of a set frequency when calculating the electric power load of the power generator. The controller executes feedback control of calculating and outputting a gear change command to the transmission driving device so an output-side rotational speed detected by the output-side speed detector becomes equal to an output-side target rotational speed corresponding to the set frequency. The controller also executes feedforward compensation of correcting the gear change command, based on the calculated electric power load.

A device and method for preventing inadvertent selection of a parking lock function in a 2-ratio transmission. Here, the shift positions of the transmission and the parking lock function thereof can be selected by way of a shift drum. A mechanically acting apparatus is provided which, in the event of rotation of the shift drum in a first direction of rotation, blocks the selection of a parking lock position of the shift drum, subsequently, in the event of rotation of the shift drum in a second direction of rotation opposite to the first direction of rotation, releases the blocking, and subsequently, in the first direction of rotation opposite to the second direction of rotation, permits selection of the parking lock position. The device does not require a separate parking lock wheel.
