A cam guiding device includes a cam guide having a cylindrical portion, a partially cylindrical portion extending from a leading end portion of the cylindrical portion, a partially tapered portion extending from the leading end portion of the cylindrical portion, and a rotation stopper portion provided on the partially cylindrical portion, and a sleeve for accommodating the cam guide. The sleeve includes an arc portion that overlaps the partially cylindrical portion from an outside. A radius of the partially tapered portion increases as the partially tapered portion extends away from the cylindrical portion. The rotation stopper portion is a component that protrudes radially outward from an outer circumferential surface of the partially cylindrical portion. When the rotation stopper portion abuts the sleeve and an inner circumferential surface of the cam guide abuts the parking cam, rotation of the cam guide with respect to the sleeve is restricted.

A transmission assembly for an electric drive comprises a drive shaft, a reduction gearing rotatably drivable by the drive shaft, a power distribution unit drivingly connected to the reduction gearing and configured to transmit a rotational motion to two output parts, a parking lock unit having a parking ratchet wheel which is connected in a rotationally fixed manner to a torque-transmitting member in the power path between the drive shaft and the output parts, and having a controllable locking element which can be selectively engaged with the parking ratchet wheel; wherein the parking lock unit is arranged in a parking lock housing which is liquid-tightly sealed with respect to a transmission housing so that a first oil bath in the transmission housing is separated from a second oil bath in the parking lock housing.

An electronic control unit of a control device for a hybrid vehicle sets any of a hybrid traveling mode, a single motor drive electric traveling mode, and a dual motor drive electric traveling mode. The electronic control unit prohibits setting of the dual motor drive electric traveling mode when a pinion temperature is higher than an upper limit temperature, and sets the hybrid traveling mode. The electronic control unit releases the prohibition of the dual motor drive electric traveling mode when the pinion temperature is decreased to or below a release temperature lower than the upper limit temperature in a state where setting of the dual motor drive electric traveling mode is prohibited. The electronic control unit restricts output of the first motor in the dual motor drive electric traveling mode when the pinion temperature is higher than the upper limit temperature.
