A method for operating a hybrid drive system of a motor vehicle, in which an internal combustion engine with a belt-driven starter generator coupled thereto is operated in an overrun mode for braking of the motor vehicle, wherein, in order to avoid a delivering of air to an exhaust system of the hybrid drive system, the internal combustion engine is configured in such a manner that intake valves and/or exhaust valves of the internal combustion engine remain closed during a rotation of a crankshaft of the internal combustion engine. Also provided is a hybrid drive system for a motor vehicle and to a motor vehicle having a hybrid drive system.

Provided herein is an auxiliary hybrid system (AHS) that may be configured to provide electrical propulsion to an e.g., internal combustion-powered vehicle through the use of a battery and electric motor. Alternatively, the AHS may be configured to increase range to electric vehicles through the use of an internal combustion-powered generator. In either embodiment, the AHS is added to a vehicle without altering the operation of the vehicles standard drivetrain, allowing the vehicle to operate conventionally when the AHS is not engaged. The AHS is compatible with a wide range of vehicles with a minimum of vehicle-specific parts.

A hybrid vehicle includes: an internal combustion engine; a first rotating electric machine generating electricity by a power of the internal combustion engine; an electric capacitor; a second rotating electric machine connected to a drive wheel and driven by power supply from at least one of the electric capacitor and the first rotating electric machine; a geographical information acquisition unit acquiring geographical information; and a control unit controlling a charging operation for charging the electric capacitor with power generated during a regenerative operation of the second rotating electric machine or an electricity waste operation for consuming the power by the hybrid vehicle. The control unit starts the electricity waste operation when the remaining capacity of the electric capacitor becomes equal to or greater than a threshold value during the regenerative operation of the second rotating electric machine and sets the threshold value based on the geographical information.

A clutch device for a motor vehicle drive train includes an input shaft, a first clutch arranged on the input shaft, a housing wall, a support bearing on the housing wall, an actuating force introduction mechanism, and a first actuating unit. The first clutch has a first clutch component with a carrier and a second clutch component. The first clutch component is directly connected to and axially supported on the input shaft. The actuating force introduction mechanism is rotationally fixed to the first clutch component such that an actuating force which adjusts the first clutch from its open position into its closed position is introduced directly into the input shaft via the carrier and is supported by the input shaft via the support bearing. The first actuating unit is operatively connected to the first clutch and includes a movable actuating bearing arranged to interact with the actuating force introduction mechanism.

A hybrid drivetrain for a hybrid powered vehicle, having an electric machine and a combustion engine, whose power output shaft acts in alternating manner either on a first input shaft or on a coaxial second input shaft of a dual clutch transmission across two separating clutches of a dual clutch, wherein a respective first and second subtransmission can be activated using the input shafts, and wherein fixed and idler gearwheels are arranged in wheel planes on the two input shafts and a common axially parallel driven shaft, said fixed and idler gears being combined into gear sets which form gear stages, in which the idler gearwheels can be coupled to the shafts by means of gear-shifting elements.

A vehicle control apparatus to be applied to a hybrid vehicle includes a continuously variable transmission, a clutch mechanism, and a travel processor. The continuously variable transmission is coupled to an engine and a first motor via an input passage, and coupled to drive wheels via an output passage. The clutch mechanism is provided on the output passage. When the travel mode is switched from a first mode in which the clutch mechanism is engaged to the second mode in which the clutch mechanism is released, the travel processor releases the clutch mechanism and stops the continuously variable transmission while maintaining a speed ratio of the continuously variable transmission. When the travel mode is switched from the second mode to the first mode, the travel processor synchronizes rotation speeds of input-side and output-side portions of the clutch mechanism by controlling the continuously variable transmission, and engages the clutch mechanism.

A vehicle includes an engine; a continuously variable transmission; an output clutch disposed between the continuously variable transmission and the drive wheel; a drive motor coupled between the output clutch and the drive wheel; a traveling mode controller; and a speed ratio controller. In a case where required driving power based on an accelerator position is less than a first threshold, the traveling mode controller switches a traveling mode to a first traveling mode. In a case where the required driving power is equal to or greater than the first threshold, the traveling mode controller switches the traveling mode to a second traveling mode. In a case where the required driving power is less than the first threshold and equal to or greater than a second threshold, the speed ratio controller causes a speed ratio of the continuously variable transmission to change depending on a vehicle speed.

An electrical machine comprising: at least one stator, at least one module, the at least one module comprising at least one electromagnetic coil and at least one switch, the at least one module being attached to the at least one stator; at least one rotor with a plurality of magnets attached to the at least one rotor, an integrated electrical differential coupled to at least one of the rotors, the at least one integrated electrical differential permitting the at least one rotor to output at least two rotational outputs to corresponding shafts, wherein the at least two rotational outputs are able to move the shafts at different rotational velocities to one another. The electrical machine is configured to fit into a housing, and that can be retrofitted into a conventional vehicle by replacing the mechanical differential.

A device for driving a vehicle including an engine that serves as a power source of the vehicle, and a transmission that is connected to the engine, the engine and the transmission being arranged transversely such that an axial direction of an output shaft of the engine accords with a right-left direction of the vehicle includes a motor generator (MG) that serves as a power source of the vehicle, and a speed reducer that is connected to the MG. The MG and at least a part of the speed reducer are arranged outside of an engine compartment that accommodates the engine and the transmission. An output shaft of the speed reducer is connected to a power transmission system, which transmits power of an output shaft of the transmission to a drive shaft of a vehicle wheel to be capable of transmitting its power to the power transmission system.

A transfer is located on an axial first side that is one side in axial direction relative to a transmission, and a rotating electric machine is located coaxially with a transmission output member, between the transmission and the transfer in the axial direction.
