A power transmission device for a hybrid vehicle may include: a cover part mounted on a vehicle body; two motor parts embedded in the cover part; two rotor parts mounted on the respective motor parts and rotated; a torsion damper part coupled to any one of the rotor parts, and connected to an engine part; a transfer part rotatably connected to the torsion damper part; a clutch part configured to selectively connect the other one of the rotor parts to the transfer part; and an output part connected to the clutch part, and configured to discharge power to a transmission.

In at least one embodiment, a system for a class 7 or 8 vehicle is provided. The system includes a first motor, a second motor, and a controller. The first motor is configured to generate torque for the vehicle. The second motor is configured to drive an engine of the vehicle such that the vehicle meets a desired speed as set forth by a driver. The controller is configured to drive at least one of the first motor and the second motor and to receive a first signal indicative of a speed of the vehicle. The controller is further configured to deactivate the first motor if the speed of the vehicle is greater than a predetermined speed limit.

A roller freewheel unit for a vehicle includes an outer sleeve element, an inner ring element and a cage element for accommodating spring/roller elements. The inner ring element has at least one radially protruding sliding shoe element, which can be inserted into a corresponding receptacle of the cage element in the axial direction in order to interconnect the inner ring element and the cage element. The inner ring element may have multiple sliding shoe elements arranged on the circumference of the inner ring element, and the cage element may have correspondingly arranged receptacles. The outer sleeve element may be slid onto outer surfaces of the sliding shoe elements in such a manner that the outer sleeve element is centered and supported by the sliding shoe elements.

A steering input device for steer-by-wire, according to the present invention, includes a steering shaft that is mechanically separated from a steered wheel, a reaction force motor that applies a steering load to the steering shaft, a lock mechanism that regulates rotation of the steering shaft, a steering amount sensor that detects an operation amount of the steering shaft and outputs an operation amount signal, and a controller. The controller increases the reaction torque generated by the reaction force motor after the starting switch of the vehicle is switched to an OFF state, and after the reaction torque is increased, switches the lock mechanism to a locked state. Thereby, it is possible to suppress an uncomfortable sensation of the driver in steering, while suppressing occurrence of a phase shift between the steering wheel and the steered wheel when the starting switch of the vehicle is switched to the OFF state.
