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 mounting structure for a drive device includes: a power generation unit having an engine and a generator driven by the engine to generate electric power; and a drive unit having a motor for traveling and a power transmission mechanism that outputs torque from the motor toward a driving wheel. A frame member of a vehicle body is provided inside an engine compartment. The power generation unit and the drive unit are arranged, inside the engine compartment, side by side in a width direction of a vehicle so as not to contact each other, and are each connected to the frame member via a mount member. Portions of the power generation unit and the drive unit, which are close to each other in the width direction, are connected by a connecting member having an anti-vibration elastic body.

Mounting structure for drive device in series hybrid vehicle

A series hybrid drive unit that is downsized while improving power transmission efficiency. In the series hybrid drive unit, a generator is driven by an engine, and a motor is operated by electricity generated by the generator. Torque generated by the generator is delivered to drive wheels through a final reduction unit. An input member that is rotated by a torque of the engine, and that is arranged parallel to a rotational center axis Og of the generator. The generator and the motor are arranged parallel to each other while keeping a predetermined clearance, and the final reduction unit is arranged parallel to the motor. The input member and the generator are connected through a first wrapping transmission mechanism, and torque of the motor is transmitted to a final reduction unit through a second wrapping transmission mechanism.

Series hybrid drive unit

An electronic control unit stores a vehicle load at the time when the vehicle is switched into an ignition off state, stops operation of an electric oil pump when the vehicle load is small, and operates the electric oil pump when the vehicle load is large. Thus, a decrease in service life due to an increase in the number of times of the start of the electric oil pump is suppressed, and, when it is estimated that the vehicle load is large, the response of the start of a vehicle, which makes a driver experience a feeling of strangeness, is improved by starting the electric oil pump together with switching the vehicle into an ignition on state.

Vehicle and control method for vehicle

An electric motor storing device for a hybrid vehicle, the hybrid vehicle including an electric motor, the electric motor including a rotor shaft and an inner circumferential side rotational shaft disposed on an inner circumferential side of the rotor shaft in a manner to penetrate said rotor shaft, and a case configured to store the electric motor, the electric motor storing device includes: a support member for rotatably supporting the inner circumferential side rotational shaft and the rotor shaft; and an insulating section for insulating between the support member and the case.

Electric motor storing device for hybrid vehicle

An electric motor includes a rotor shaft, and the rotor shaft has a shaft-core oil passage and radial oil passages. The shaft-core oil passage includes an inner wall facing radially inward. The radial oil passages are provided toward a radial outer side of the rotor shaft from the shaft-core oil passage. The radial oil passages penetrate through the rotor shaft. The radial oil passages have corresponding one of first connection openings connected to the shaft-core oil passage, so that oil that is not discharged from the first connection openings to the radial oil passage is supplied to other supply destinations. A distance of the first connection openings from the shaft core is shorter than a distance, from the shaft core, of that part of the inner wall which is not provided with the first connection openings.

Electric motor

A first check valve of a hydraulic control system allows oil to flow in only a direction from a first oil pump toward an oil receiving portion. A second check valve allows oil to flow in only a direction from a second oil pump toward the oil receiving portion. A third oil passage is configured to provide communication between a merging point of a first oil passage and a second oil passage, and the second oil pump by bypassing the second check valve. The third oil passage includes a throttle mechanism. The third oil passage is configured to restrict a flow rate of oil that is discharged from the second oil pump.

Hydraulic control system for vehicle

A hybrid drive apparatus and a control apparatus for controlling the hybrid drive apparatus, a hybrid drive apparatus including a differential device made of a first differential mechanism and second differential mechanism, including four rotary components; and an engine, a first electric motor, second electric motor and an output rotary member, which are respectively connected to four rotary components, wherein one of the four rotary components consists of a rotary element of the first differential mechanism and a rotary element of the second differential mechanism which are selectively connected to each other through a coupling element, and the control apparatus controlling at least one of output torques of the first and second electric motors, to reduce a difference between rotating speeds of the rotary elements of the first and second differential mechanisms selectively connected to each other through the coupling element, to a value not larger than a predetermined threshold value, before the coupling element is brought into an engaged state when the drive system is re-started after the drive system is once placed in an off state.

Drive system of a hybrid vehicle

A control apparatus for a hybrid vehicle drive system, which permits effective reduction of deterioration of the drivability of the hybrid vehicle. The control apparatus includes a drive mode switching portionconfigured to switch the hybrid vehicle drive system from a hybrid drive mode to a first EV drive mode if an electric energy amount stored in a battery is smaller than a predetermined threshold value &#x3b1; or if a vehicle drive force required to be generated by the hybrid vehicle drive system is smaller than a predetermined threshold value &#x3b2;, and to a second EV drive mode if the electric energy amount stored in the battery is equal to or larger than the threshold value &#x3b1; and if the drive force required to drive the hybrid vehicle is equal to or larger than the threshold value &#x3b2;, when the drive mode switching portion has determined that the hybrid vehicle drive system should be switched from the hybrid drive mode to the first or second EV drive mode.

Control apparatus for a hybrid vehicle drive system

A vehicle parking lock device having a parking rod; a tapered parking cam disposed at a leading end portion of the parking rod; and a cam guiding device that guides the parking cam moved together with the parking rod in association with a projection of the parking rod toward the leading end portion to move a parking lock pole with the parking cam to a position of engagement with a parking lock gear rotated together with a transmission output member, the cam guiding device including a first guiding member in a cylindrical shape and a second guiding member in a half cylindrical shape that is disposed subsequently to the first guiding member, the second guiding member having a tapered guiding concave surface that guides the parking cam toward the parking lock pole in association with the projection of the parking rod toward the leading end portion.
