A vehicle includes a step-ratio automatic transmission having clutches engageable to provide forward and reverse gears, an electric machine selectively coupled to the transmission, a main pump powered by the electric machine and supplying oil to actuate selected transmission clutches, a gear selector configured for selecting a transmission gear, and a controller configured to stop the electric machine when the gear selector selects park or neutral, to operate the electric machine in a speed control mode using a higher controller gain in response to the gear selector selecting forward or reverse while the electric machine is stopped until the electric machine and the main pump reach a first speed threshold to reduce engagement delay of at least one of the transmission clutches, and to operate the electric machine using a lower controller gain when the electric machine and the main pump exceed the first speed threshold.

The present disclosure discloses a power drive system and a vehicle, the power drive system including: an engine; a transmission having a transmission power output portion; a first electric generator, the engine and the first electric generator being connected through the transmission by means of power coupling; and a differential having a differential power input portion and two differential power output portions, the differential power input portion being linked with the transmission power output portion, each of the differential power output portions being connected with a wheel on the same side, and a power engagement device being provided between one of the differential power output portions and the wheel on the same side.

A transmission includes first, second, and third planetary gear sets (PGS). A first electric machine is fixedly coupled to a sun gear of the first PGS. A second electric machine is fixedly coupled to a carrier of the first PGS. A brake is selectively holding a ring gear of the first PGS against rotation. First and second clutches selectively couple the first and second electric machines, respectively, to a portion of the second and third PGS, respectively.

Systems and apparatuses include a cab floor defining a center plane, a seat slide actuator coupled to the cab floor and selectively moveable in a direction transverse to the center plane relative to the cab floor, and a seat supported by the seat slide actuator and moveable therewith.

A method for operating a motor vehicle including an all-wheel drive that can be enabled and disabled, and a drive train including two clutches actuated by a control unit for enabling and disabling the all-wheel drive, and components rotating between the two clutches, which components are driven when the all-wheel drive is enabled and are uncoupled from the remaining drive train when the all-wheel drive is disabled. In order to allow early detection of defects and, in particular, bearing defects of the rotating components, and to determine the applied drag torque even without knowing the oil temperature, in one embodiment, when the all-wheel drive is disabled, the rotational speed (n) of at least one of the uncoupled components is measured in a time interval, and an angular acceleration of the uncoupled components is determined therefrom.

Systems and methods for operating a driveline of a hybrid vehicle are disclosed. In one example, an engine may enter or stay in one of two cylinder modes in response to a request to a negative torque capacity of an electric machine being insufficient to provide a desired driveline braking torque. One cylinder mode operates cylinders with cylinder valves held closed and without fuel being injected to the cylinders while the other cylinder mode operates cylinders with valves that open and close without fuel being injected to the cylinders.

In a vehicle that includes an engine including a starter, an automatic transmission unit having an input shaft coupled to an output shaft of the engine via a first clutch, and a motor generator (hereinafter, referred to as MG) coupled to the input shaft of the automatic transmission unit via a second clutch, an electronic control unit starts up the engine with the use of the starter in a state where the MG is disconnected from the engine by releasing at least one of the first clutch or the second clutch when an IG-on operation has been made in an IG-off state (a state where the vehicle is stopped in a P range) and a power control unit that supplies electric power to the MG has a failure.
