When a first type gear shift line is used as a gear shift line to change the gear ratio, and a predetermined condition including a condition that a state of charge of the power storage device is equal to or lower than a first ratio is satisfied, the control device changes the gear shift line to a second type gear shift line that recommends a lower speed gear ratio than the first type gear shift line.

A drive unit for a skid steered vehicle includes a controlled differential positioned between two shafts. The end of each shaft forms an output of the drive unit connected directly to the differential outputs via the shafts. A steer motor is in driveable communication with the differential, and an electric propulsion motor is in driveable communication with the shaft outputs. A gear reduction unit, and optional gear change unit, is positioned between the differential and the electric propulsion motor. The electric propulsion motor, the gear reduction unit and optional gear change unit are connected in a parallel connection with an output of the differential to the shaft outputs. The optional gear change unit includes an epicyclic gear reduction unit having an input and an output which provides drive input from the gear change unit to the shaft. A gear change set has a master gear that receives drive output from the electric propulsion motor, and slave gears which are driven by the master gear via one or more gear chains. A dog clutch slideably engages the input of the gear reduction unit and selectively engages with the master gear or slave gears so that the selected position of the dog clutch determines which gear is engaged.

A gear unit for a powertrain of a vehicle includes a stepped planetary gearset, a first gear shifting element and a second gear shifting element. The stepped planetary gearset has at least a first ring gear, a second ring gear and a plurality of stepped planet gears rotatably mounted at a first planet carrier. The first planet carrier drivingly connects to an electric machine. The second ring gear is connected to an output shaft of the gear unit so as to be fixed with respect to rotation relative to it. The first gear shifting element fixes the first ring gear relative to a housing in a closed state, and the second gear shifting element brings the stepped planetary gearset into direct drive in a closed state. One of the two gear shifting elements is in the closed state for driving the output shaft in rotation.

Desired is a control device for a vehicle drive apparatus capable of determining an engagement failure in an engagement device when shifting a transmission device to a neutral state and making the rotational speed of a driving force source reduced. In order to shift a transmission device from a state in which an object shift speed is established and the vehicle is traveling to a neutral state in which no shift speed is established in the transmission device (#02), when an object engagement device is disengaged while maintaining engagement of a non-object engagement device and the rotational speed of a driving force source (#04, #06) is made to be reduced, an engagement failure in the object engagement device (#02, #07) is determined based on a change in the rotational speed of an input member.

The invention relates to a motor vehicle transmission (6) comprising a drive input shaft (9), a drive output shaft (10), a first planetary gearset (P1), a second planetary gearset (P2), and a third planetary gearset (P3), where the drive input shaft (9) is provided for coupling to an electric machine (5). Furthermore, at least functionally a first shifting element (A), a second shifting element (B), and a third shifting element (C) are provided. In addition, the invention relates to a drive unit (4), a drive axle (3), and an electric vehicle.

A hybrid drive unit (HY, G) for a motor vehicle includes a housing (GG), in which a torque converter (TC) and an electric machine (EM) are accommodated. The electric machine (EM) and the torque converter (TC) are arranged directly next to each other such that the electric machine (EM) is arranged at a first face end (TC1) of the torque converter housing (TCG). An oil guide shell (LS) at least partially encompasses a section of the torque converter (TC). The oil guide shell (LS) has an L-shaped cross-section including a first section (LS1) and a second section (LS2) and is arranged in such that the first section (LS1) partially encompasses a second face end (TC2) of the torque converter housing (TCG) and the second section (LS2) partially encompasses a circumferential surface of the torque converter housing (TCG).

In a hybrid vehicle, when a required driving force is equal to or smaller than a first upper limit driving force, a control device sets a target driving force to the required driving force. When the required driving force is larger than the first upper limit driving force, the control device sets a target compensation power of a power storage device, based on a difference between the required driving force and the first upper limit driving force. The control device sets a second upper limit driving force of a driveshaft when an upper limit power is output from an engine and the power storage device is charged or discharged with a power based on the target compensation power. The control device sets a target driving force to the smaller between the required driving force and the second upper limit driving force. This configuration suppresses deterioration of the driver's drive feeling.
