A drive train for installation in a vehicle chassis includes a power source, two motor/generators (M/Gs), an array of batteries, and a control system for configuring the drive train to operate using only the power source, only the batteries or a combination of the power source and batteries. The control system may open or close clutches to configure the drive train with each M/G working as a motor or a generator. A M/G working as a motor may use power from the batteries to supply rotational power to drive the vehicle or operate accessories on the vehicle. A M/G working as a generator coupled to a power source generates electric power for charging the array of batteries. The vehicle, including components and subsystems, may be powered electrically from the batteries or powered from the engine.

A four-wheel drive vehicle includes a drive-power distribution device including (a) a clutch for distributing an engine drive power, between main and auxiliary drive wheels, (b) an electric motor, (c) a press mechanism for pressing the clutch by converting a rotary motion of the electric motor into a linear motion. The drive-power distribution device adjusts a torque capacity of the clutch to adjust a drive-power distribution ratio between the main and auxiliary drive wheels. The vehicle further includes a control apparatus for executing a drive-power distribution control for adjusting the drive-power distribution ratio, and an automatic-stop control for causing the engine to be automatically stopped upon satisfaction of an engine-stop condition. When the engine is in a stop state by execution of the automatic-stop control, the control apparatus inhibits change of the drive-power distribution ratio which is to be made by change of a rotational direction of the electric motor.

A method of controlling an axle assembly includes providing an axle assembly in a first state. A first controller is provided in electrical communication with the axle assembly. The first controller determines if a source of power has an available amount of electrical energy that is within a predetermined range and a predetermined period of time has elapsed. If the available amount of electrical energy is within the predetermined range and the predetermined period of time has elapsed, then electrical energy is transferred from the source of power to an electric motor generator and an axle disconnect clutch is engaged to provide the axle assembly in another state.

Disclosed is a method of controlling a hybrid electric vehicle having a transmission, an engine, and first and second drive motors. The method includes: performing charging through the first drive motor using the power of the engine by engaging an engine clutch disposed between the engine and the first drive motor while a vehicle is stopped with the gear stage shifted to the parking (P) range; turning off the engine and controlling the clutch of the transmission to enter an open state when the gear stage is shifted to the driving (D) range; and commencing movement of the vehicle using the second drive motor alone or using at least one of the first drive motor or the engine together with the second drive motor based on at least one of requested torque, available torque of the second drive motor, or the speed of the first drive motor.

The present disclosure relates to a hybrid vehicle control device, a system including the same, and a method thereof. The hybrid vehicle control device according to an embodiment of the present disclosure includes a processor and storage. The processor sets a target engine speed and determines presence or absence of a kick down shift based on the vehicle driving situation, and performs engine clutch engagement control according to a result of the kick down shift. The storage stores the vehicle driving situation and a result of the determination of the presence or absence of the kick down shift.

A method of controlling the engine of a vehicle having a stop-in-gear (SIG) stop-start system includes: a control module determining that a brake is being applied, based on an output from a brake sensor, and that a transmission is in an in-gear position, based on an output from a transmission sensor; and, while the brake is applied and the transmission is in an in-gear position, the control module causing the engine to start in response to detecting movement of a clutch pedal towards a released position based on an output from a clutch pedal sensor.

A method for exiting from a recuperation phase in a parallel hybrid vehicle includes, in a first step, the vehicle is in a recuperation phase, started by means of a trigger, with a predefined recuperation driving demand, and, in a second step, the electric machine is brought to an increased rotational speed during the recuperation phase. In a third step, a phase for departing from the recuperation phase is started by means of a trigger, wherein, in this phase, the internal combustion engine is made available for coupling to the electric machine, such that a target rotational speed determined between the internal combustion engine to be connected and the electric machine for the connection to the transmission input is set, and in parallel, by means of an upshift, a highest possible gear ratio for the connection to the drivetrain is set, in order to satisfy a present driving demand. In a fourth step, the departure from the recuperation phase is completed.

In a cruise control method and a cruise control apparatus for a manual transmission vehicle, upon receiving a signal from an input device to start a cruise mode, a cruise control controller calculates an optimal gear stage for satisfying a target cruise traveling speed according to a traveling state of a vehicle, and a display device displays the calculated optimal gear stage to the driver to induce the driver to shift to the optimal gear stage. In addition, whether the gear stage by the driver's operation has matched the optimal gear stage may be determined within a predetermined time to determine whether a cruise control continues according to the determination result, thereby eliminating the driver's inconvenience due to frequent cancellation of the cruise mode.

A method to control the execution of a shift to a lower gear with a released accelerator pedal in a drivetrain provided with a dual-clutch, servo-assisted transmission; the following steps are provided: opening, in a first instant, an outgoing clutch; closing, in the first instant, an incoming clutch; completing the opening of the outgoing clutch with a first linear ramp in a second instant; synchronizing, between the second instant and a third instant, a rotation speed of the internal combustion engine with a rotation speed of the incoming clutch; closing of the incoming clutch with a second linear ramp starting from a fourth instant, which is prior to or coincides with the second instant; completing the closing of the incoming clutch in a fifth instant, which coincides with or is subsequent to the second instant; and activating the internal combustion engine so as to generate a torque between the fourth instant and the third instant.

A transmission includes an input shaft coupled to a prime mover, a countershaft, main shaft, and an output shaft, with gears between the countershaft and the main shaft. A shift actuator selectively couples the input shaft to the main shaft by rotatably coupling gears between the countershaft and the main shaft. The shift actuator is mounted on an exterior wall of a housing including the countershaft and the main shaft. A controller controls the shift actuator utilizing an actuating pulse and an opposing pulse.
