A method for operating a hybrid drive assembly for a motor vehicle, which has an internal combustion engine and an electric engine. A separating clutch arranged in drive terms between the internal combustion engine and the electric engine is set to a target clutch torque by at least partially engaging during an attempt to start the internal combustion engine. An actual clutch torque actually transmitted via the separating clutch and a speed of the internal combustion engine are determined during the attempt to start, and if a characteristic value dependent on the actual clutch torque exceeds a threshold value and if an integral of the speed over time continuously falls below a limit value during the attempt to start, the attempt to start is aborted.

A hybrid drive module is disclosed. An exemplary embodiment of the present invention provides a hybrid drive module that selectively transmits torque transmitted from an engine and a motor to a transmission including a housing disposed between the engine and the transmission, a drive shaft rotatably mounted inside the housing in a radial direction with its one end portion toward the engine based on an axial direction protruding from the housing and to which torque of the engine is inputted, a rotor hub provided within the housing and mounted with a rotor of the motor on its radially outer side, and in which a hub plate part integrally extending toward the drive shaft and rotatably connected to the other end portion of the drive shaft toward the transmission based on the axial direction is formed on its radially inner side, a rotor hub ridge, an inner circumferential surface of which is rotatably supported by the housing based on the radial direction and an external circumferential surface of which is fixed to the rotor hub based on the axial direction at the side of the engine, an engine clutch disposed at the engine side in the axial direction with the hub plate part interposed therebetween, and configured to directly connect the drive shaft and the rotor hub to selectively transmit the torque of the engine to the rotor hub, and a torque converter disposed at the side of the transmission in the axial direction with the hub plate part interposed therebetween to be connected to the rotor hub, and configured to multiply the torque of the engine, torque of the motor, or the torque of the engine and the motor when a vehicle is initially driven, or to transmit it to the transmission in a ratio of 1:1, wherein at least one fluid groove for supplying an operating fluid to the rotor to cool the rotor between the rotor hub and the engine clutch is formed on a surface of the hub plate part toward the engine clutch based on the axial direction.

A hybrid drive sub-assembly for a vehicle, including primary toothed wheels, secondary toothed wheels capable of being coupled to a secondary shaft, an intermediate shaft to which intermediate toothed wheels are rigidly connected for rotation therewith, the primary toothed wheel(s) and the secondary toothed wheel(s) each permanently meshing with a corresponding toothed wheel of the intermediate toothed wheels. This hybrid sub-assembly is provided with a motorized module including a reversible electric machine, an interface for connection to the intermediate shaft, a speed reducer, a power take-off member and a dual clutch mechanism capable of coupling and uncoupling the power take-off member to and from the reversible electric machine and the intermediate shaft.

Systems and methods of controlling a clutch in a hybrid vehicle with a manual transmission, are provided. With the goal of enabling autonomous/assisted clutch control in a hybrid vehicle, while preserving the familiar mechanical feeling at the clutch pedal that driving enthusiasts prefer, embodiments of the disclosed technology use a shuttle valve to blend control of clutch engagement between a driver and an ECU. In these embodiments, a clutch pedal in the vehicle may be mechanically connected to a piston in a first hydraulic cylinder (just like in a traditional mechanical/hydraulic clutch actuation system), and an ECU may actuate a second hydraulic cylinder. Accordingly, a shuttle valve may be used to route the fluid coming from the cylinder with the greater pressure (i.e. the driver actuated cylinder or the ECU actuated cylinder), to a third hydraulic cylinder which adjusts engagement of a clutch by a mechanical linkage.

An active vibration reduction control apparatus for a hybrid electric vehicle includes: a reference signal generator generating a reference signal and a first phase based on a first rotational angle of a first motor; a vibration extractor extracting a vibration signal from a second motor; a coefficient determiner determining a filter coefficient which minimizes a phase difference between the reference signal and the vibration signal; a phase determiner detecting a second phase which corresponds to the phase difference using a first speed signal of the first motor and the filter coefficient; a phase deviation amount detector detecting a third phase for compensating for a phase delay; and a synchronization signal generator generating an antiphase signal of a shape of an actual vibration in order to determine a compensating force of the first motor.

A first electric power generation device configured to produce an accessory voltage according to a first instruction voltage. A second electric power generation device configured to produce the accessory voltage according to a second instruction. An electric control unit is configured to execute crank position stop control for stopping a crank of the engine at a target position when the engine is stopped by controlling the first electric power generation device such that a current is circulated in the first electric power generation device and the rotating electric machine generates braking torque. The electric control unit is configured to execute the crank position stop control in a state in which the second instruction voltage is equal to or higher than the first instruction voltage.

A system and method for modifying the engine pull-up (EPU) logic within a hybrid vehicle based on max motor torque that accounts for the drop or change in available motor torque due to the opening/slipping of a torque converter bypass clutch during engine starts is disclosed. An engine pull-up threshold is determined from max available motor torque at a virtual impeller speed, where the virtual impeller speed is the impeller speed that would result if the torque converter bypass clutch was open/slipping and transferring the same amount of torque.

Presented are clutch-type engine disconnect devices, methods for making/using such disconnect devices, and motor vehicles equipped with such disconnect devices. An engine disconnect device includes a notch plate, which has multiple notches and attaches to a torque converter, and a pocket plate, which has multiple pockets and attaches to an engine's crankshaft. A pawl is movably mounted within each notch; these pawls selectively engage the notches with the pockets. A notch plate insert is nested within each notch, supporting thereon one of the pawls. A selector plate interposed between the pocket and notch plates moves from a first position, to shift the pawls out of engagement with the pockets, and a second position, to move the notch plate inserts within the notches and allow the pawls to engage the notches with the pockets to thereby lock the notch plate to the pocket plate to rotate in unison with each other.

A vehicle control system includes a first electric motor that causes a vehicle to travel, a second electric motor that generates power by using an output of a power source and starts the power source, a power storage device that stores the power generated by the second electric motor and supplies the power to the first electric motor, a monitoring device that monitors a failure state of the vehicle, and a switch that switches the vehicle to travel from the first electric motor to the second electric motor. In a case of a predetermined driving state in which the monitoring device detects a failure of the first electric motor and a driving force is obtained from the second electric motor, the monitoring device controls the switch to switch the driving force for causing the vehicle to travel from the first electric motor to the second electric motor.
