A control apparatus of an automatic transmission, which includes a mechanical engaging mechanism functioning as a brake, includes a determination unit determining, when a selected gear is a lowest forward speed gear, and the mechanism is in a second state, whether to switch the mechanism to the first state, and a switching processing unit switching the mechanism to the first state based on a determination result. In the first state, only rotation of a predetermined rotational element provided in planetary gear mechanisms in a first direction is restricted. In the second state, rotation of the predetermined rotational element in both the first and second direction is restricted. The determination unit determines to switch the mechanism to the first state at least on condition that a driving force is larger than a predetermined driving force.

A motor vehicle control system that includes a first user-operable transmission selector for selecting a transmission operating mode and a user-operable gear selector, such as paddle input controls. The gear selector is operable in a first functional mode to select between a plurality of forward direction gear ratios. The gear selector is also operable in a second functional mode to select between a forward direction and reverse direction. This allows a user to use the gear selector to control travel in forward and reverse directions.

Methods and systems are provided for operating a vehicle that includes an electric machine as a propulsion source. In one example, a motor stall assessment level is generated based on an amount of time that the motor is stalled and an amount of torque that is generated by the motor. Mitigating actions may be performed if the motor stall assessment level exceeds a threshold level or value.

A method is disclosed for controlling a change in the direction of travel of a working vehicle between forward travel and rearward travel or vice versa. The working vehicle has an electronically controllable hydrostatic travel drive, a power-operated brake system with at least one electronically controllable brake circuit, and an electronic brake-control unit for controlling the travel drive and the brake circuit. While the vehicle is traveling in a first direction, a change in the direction of travel is triggered by a switchover of the hydrostatic travel drive by means of an assigned manual operating element. To reduce the mechanical loading, the deceleration of the working vehicle can be assisted by automatically actuating the brakes of the electronically controllable brake circuit, where these brakes are actuated by being triggered by the switchover of the operating element and are released by the time the vehicle comes to a standstill.

A vehicle control apparatus includes a detection section, a control section. The detection section is configured to detect vehicle information including a vehicle speed of a vehicle driven by an electric motor and drive torque of the electric motor. The control section is configured to moderate a rate of increase in the drive torque at the time of acceleration with respect to a rate of increase set in advance on the basis of a detection result of the detection section on condition that the vehicle speed of the vehicle is less than or equal to a predetermined speed and the drive torque is greater than or equal to a predetermined threshold.

A vehicle controller configured to control a vehicle which includes a transmission gear includes at least one electronic control unit. The at least one electronic control unit is configured to: determine whether a shift range of the transmission gear is switched such that the vehicle travels in a changed traveling direction not based on a shift range switching operation by an occupant of the vehicle; and limit, when it is determined that the shift range is switched such that the vehicle travels in the changed traveling direction not based on the shift range switching operation, a driving force of the vehicle such that the driving force of the vehicle is smaller than when it is determined that the shift range is not switched such that the vehicle travels in the changed traveling direction not based on the shift range switching operation.

Methods and systems for autonomously closing an open door of a vehicle are disclosed. A door closing system for a vehicle includes a sensor system and an autonomous driving system. The sensor system determines if a door of the vehicle is open and determines if a surrounding of the vehicle is free of obstacles in a predetermined range. The autonomous driving system instructs the vehicle to move if a door of the vehicle is open and if the predetermined range of the surrounding of the vehicle is free of obstacles, such that the door is closed as a result of the movement of the vehicle.

A reversing method for reversing a travel direction of a working machine with a power-split transmission in which control signals are emitted by a control unit such that a reversing clutch, for the current travel direction, is disengaged and a reversing clutch for the new travel direction is engaged. The reversing clutches are controlled by control variables. If there is a difference between a reference control magnitude and a target control variable, the control variable is adapted. An adapted control signal is emitted, with which the reversing clutches are actuated, and for determining the target control variables for the disengaging and engaging of the reversing clutches, in addition to a translational factor and a rotational factor a load-dependent factor is determined and processed.

An agricultural, construction, or industrial vehicle or machine has a driveline including an engine, a power-shuttle transmission connected to the engine, and at least one drive axle driven by an output shaft of the power-shuttle transmission. The power-shuttle transmission has an input shaft, a forward shuttle gear train, and a reverse shuttle gear train. Each shuttle gear train has a shuttle clutch selectively coupling it with the input shaft. The forward shuttle gear train drives the output shaft when the forward shuttle clutch is engaged, and the reverse shuttle gear train drives the output shaft when the reverse shuttle clutch is engaged. The at least one drive axle has at least one service brake. A hydraulic energy recapture system is coupled to the output shaft of the power-shuttle transmission and works in cooperation with the shuttle clutches and with the service brakes.

Methods and apparatus to extricate a vehicle from a stuck condition, apparatus, systems and articles of manufacture are disclosed. An example apparatus includes: a user interface to receive a command to place a vehicle in an autonomous control mode of the vehicle; and a stuck mode controller to autonomously shift a transmission of the vehicle alternately between a reverse gear and a forward gear of the vehicle when in the autonomous control mode to autonomously rock the vehicle back and forth. A timing of the shifting of the transmission is based on a ratio of a velocity of the vehicle to an acceleration of the vehicle.
