A control device of a hybrid vehicle including an engine, motor that receives power from the engine via an engine connecting and disconnecting device, and automatic transmission, starts the engine in a first starting method in which the engine performs ignition and rotates by itself after the engine speed is increased to be equal to or higher than a predetermined rotational speed through slipping engagement of the engine connecting and disconnecting device, or a second starting method in which the engine performs ignition and rotates by itself from a stage before the engine speed reaches the predetermined rotational speed, and controls the automatic transmission to permit a lower gear position to be established according to shift conditions when the engine is started in the second starting method during a downshift of the automatic transmission, as compared with when the engine is started in the first starting method during the downshift.

The rotor assembly has an electric motor rotor and a thrust surface for a K0 clutch. The K0 clutch is arranged to drivingly connect the rotor assembly to the K0 shaft. The rotor carrier is fixed to the rotor assembly and the first bearing is arranged to rotationally separate the bulkhead wall and the rotor carrier. In an example embodiment, the first bearing is a deep groove ball bearing. In an example embodiment, the hybrid module includes a seal installed in the bulkhead wall and contacting the K0 shaft. In an example embodiment, the hybrid module includes a bushing installed on the K0 shaft and arranged for contacting an inner bore of the crankshaft.

An in-vehicle control device mounted on a vehicle includes an electronic control unit configured to determine that there is a possibility that damage to a bottom portion of the vehicle occurs when a vertical acceleration, which is an acceleration in a vertical direction of the vehicle, or a vertical acceleration increase rate, which is an amount of increase in the vertical acceleration per unit time, reaches a first threshold value or higher.

A controller as a control apparatus for a hybrid vehicle determines whether or not to perform switching from a first traveling mode in which a hybrid vehicle is caused to travel using torque of a motor without using torque of an engine to a second traveling mode in which the hybrid vehicle is caused to travel using at least the torque of the engine. The controller, when determining that switching is to be performed from the first traveling mode to the second traveling mode, performs control to reduce output torque of the motor by a predetermined amount. After this control, the controller shifts a first clutch from a released state to an engaged state so that the torque of the motor is transmitted to the engine via the first clutch, and cranks the engine using the motor to start the engine.

A hybrid electric vehicle and a method for compensating a motor torque thereof, may include a hybrid control unit (HCU) including a processor and a non-transitory storage medium containing instructions executed by the processor. The processor is configured to start motor torque intervention upon entering a predetermined shift phase during shifting, to determine a motor torque compensation amount by reflecting engine torque according to engine torque reduction control, and to perform motor torque compensation control based on the motor torque compensation amount.

A transmission (2) of a motor vehicle includes a first input shaft (7) for a first prime mover (3), a second input shaft (8) for a second prime mover (4), and an output shaft (9). A first sub-transmission (5) includes the first input shaft and a countershaft (11) coupled to the first input shaft (7) via a constant ratio. Gearwheels (16, 17, 18) are arranged on the countershaft, which mesh exclusively into gearwheels (12, 13, 15) arranged coaxially to the first input shaft (7). At least some of these gearwheels mesh into gearwheels (20, 21) arranged on the output shaft (9). Shift elements (A, B, C, D) are associated with the first input shaft (7) as well as with the countershaft (11), which provide either a gear with a first number of instances of gearwheel meshing or a winding-path gear with a second number of instances of gearwheel meshing. A second sub-transmission (6) includes the second input shaft (8), which is designed as a planetary transmission. A ring gear (22) forms the second input shaft (8), and a carrier (23) is coupled to the output shaft (9) via a gearwheel (14) arranged coaxially to the first input shaft (7). Shift elements (F, E) are associated with the planetary transmission, via which a sun gear (24) is fixedly connectable to the housing or the planetary transmission is bringable into direct drive. A sub-transmission coupling of the sub-transmissions is providable via one of the shift elements (A) associated with the countershaft.

In particular, the controller controls the drive motor and the first and second electric superchargers based on a supercharger consumed energy, an additional fuel energy, and a drive motor consumed energy.

An electric machine includes a rotor-integrated clutch for a drive train of a motor vehicle, and has a stator and a rotor. The rotor has a carrier, on which a first part of a friction clutch configured for a force-locking connection with a second part is attached, wherein a coolant fluid line is provided in order to supply the stator or the rotor with coolant fluid to bring about heat dissipation. The coolant fluid line is arranged and perforated such that the coolant fluid both drips under gravity onto a section of the rotor in order to generate a spray mist, and flows over the outer surface of the stator.
