The invention relates to a method for operating a hybrid drive device (2) which has an internal combustion engine (3) and an electric machine (4) which can be or is operatively connected to the internal combustion engine (3) and can be operated as a generator, wherein in a normal operating mode a temperature of the electric machine (4) is determined by means of a temperature sensor (14), and operation of the electric machine (4) is permitted only if the temperature is lower than a predefined maximum temperature. There is provision here that in the event of a defect in the temperature sensor (14) an emergency operating mode is carried out in which operation of the electric machine (4) is permitted only with limited power, limited torque and/or over a limited time period.

A powertrain for a hybrid vehicle may include a planetary gear set including five rotation elements, an input shaft connected to an engine and configured to be selectively connectable to a first rotation element and to a fourth rotation element of the planetary gear set, a motor generator connected to a second rotation element of the planetary gear set, an output shaft connected to a third rotation element of the planetary gear set, and a brake configured to selectively fix the fifth rotation element of the planetary gear set to a transmission housing.

The present disclosure is directed to an electric generator and motor transmission system that is capable of operating with high energy, wide operating range and extremely variable torque and RPM conditions. In accordance with various embodiments, the disclosed system is operable to: dynamically change the output “size” of the motor/generator by modularly engaging and disengaging rotor/stator sets as power demands increase or decrease; activate one stator or another within the rotor/stator sets as torque/RPM or amperage/voltage requirements change; and/or change from parallel to series winding configurations or the reverse through sets of 2, 4, 6 or more parallel, three-phase, non-twisted coil windings with switchable separated center tap to efficiently meet torque/RPM or amperage/voltage requirements.

A control method for a hybrid power system. The method is applied to a hybrid power system composed of an engine (10) and a motor (20). A motor stator (21) of the motor (20) is connected to a driving shaft (40) of a motor vehicle by means of a transmission mechanism (32) such that, when rotated, the driving shaft (40) drives the motor stator (21) to rotate; the motor (20) is used to determine output torque according to the rotating speed of the motor and transmit same to the driving shaft (40); the rotating speed of the motor is equal to the difference between the rotating speed of the motor rotor (22) and the rotating speed of the motor stator (21). The method comprises, according to operating parameters of the hybrid power system and operating parameters of the motor vehicle, controlling a motor controller to provide a drive signal to the motor stator such that the operating parameters of the motor meet a first preset formula, thereby avoiding the possibility of the motor operating at zero rotating speed or within a low rotating speed range under various operating conditions, avoiding the occurrence of problems with the motor such as efficiency and torque response being poor under such operating states, and improving user experience. Also provided is a control system for achieving a control method for a hybrid power system.

A hybrid drive assembly having an e-motor with a housing fixed stator and a rotor that connects to a transmission. The e-motor rotor includes a rotor support having a mounting flange with a stop at one end. A diaphragm spring clamps a second rotor ring, a rotor stack, and a first rotor ring against the stop to rotationally fix the rotor stack to the mounting flange. A drive plate assembly for connection to a crankshaft includes an output flange that is: (a) frictionally engaged to the diaphragm spring and/or the second rotor ring such that upon application of a torque spike the output flange rotates relative to the diaphragm spring and/or the second rotor ring, or (b) rotationally fixed to the diaphragm spring such that upon application of a torque spike the diaphragm spring rotates relative to the mounting flange, forming in each case an overload clutch.

Provided is a hybrid power system, which is composed of an engine (10) and a motor (20). A motor stator (20) of the motor is connected with a drive shaft (40) of a motor vehicle through a transmission mechanism, so that the motor stator can also rotate relative to the chassis and other structures of the motor vehicle, thus, the hybrid power system composed of the engine and the motor can meet the application of various working conditions such as starting, idling, forwarding and reversing of the motor vehicle, and the number of parts of the hybrid system is greatly reduced, thereby simplifying the overall structure of the hybrid power system.

A transmission system for a hybrid power plant, such as a hybrid propulsion system of a marine vessel, is described. The transmission is configured to selectively couple a primary mover and/or a secondary mover to an output of the transmission for providing a power output, and optionally selectively couple the primary mover to the secondary mover, decoupling the output, for electrical energy generation in a compact and light-weight design.

A vehicle powertrain includes a first power-source configured to generate a first power-source torque and a multiple speed-ratio transmission configured to transmit the first power-source torque to power the vehicle. The powertrain also includes a fluid coupling having a fluid pump shaft operatively connected to the first power-source and a turbine shaft operatively connected to the multi-speed transmission. The fluid coupling is configured to multiply the first power-source torque, and transfer the multiplied first power-source torque to the multiple speed-ratio transmission. The powertrain additionally includes a second power-source configured to generate a second power-source torque and a first torque transfer system configured to connect the second power-source to the first power-source. The powertrain further includes a second torque transfer system configured to connect the second power-source to the multi-speed transmission. A motor vehicle having such a powertrain is also envisioned.

The driveline of the military vehicle includes an engine and an integrated motor generator (IMG) and the FEAD includes multiple accessories and an electric motor-generator. The modes include an engine mode and an electric mode. In the engine mode, the engine drives the FEAD and drives tractive elements of the military vehicle through the IMG for transportation. In the electric mode, the engine is shut off to reduce a sound output of the military vehicle and the IMG drives the tractive elements of the military vehicle for transportation and the electric motor-generator drives the FEAD.
