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 apparatus to extricate a vehicle from a stuck condition, apparatus, systems and articles of manufacture are disclosed. An example method includes receiving a command to place a vehicle in a stuck mode. The stuck mode corresponds to an autonomous control mode of the vehicle. The method further includes autonomously controlling the vehicle in the stuck mode to attempt to extricate the vehicle from a stuck condition.

A vehicle may include a processor programmed to control operation of the vehicle. The processor may control operation of the vehicle according to an indication of a direction of travel. The indication of direction of travel may be based on signs of data representing jerk of the vehicle. The signs of data representing jerk may be derived from acceleration and speed sensor outputs. The indication may be such that the indication is reverse in response to the signs being opposite when the vehicle is in a forward drive gear.

A method for rocking a motor vehicle free. The vehicle has a drive-train with an automatic drive torque adjusting element, which transmits torque to a wheel, and a rotational speed and direction sensor system for detecting movement of the vehicle such that when the accelerator pedal is biased to a position different from its non-actuated position a desired drive torque can be produced. The torque adjusting element can be controlled based on the accelerator pedal position in relation to the drive torque that can be produced by the driver, and, in a rocking-free process, alternating deflection and release of the accelerator pedal causes the drive torque to fluctuate. With the rotational speed and direction sensor system, the drive torque adjusting element is controlled to suppress drive torque transmission if the travel direction of a current unpowered vehicle movement is not the same as a forthcoming power-driven vehicle movement.

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.

A method for operating a dual-clutch transmission of a vehicle having partial transmissions with respective transmission input shafts. Two friction clutches can couple a corresponding input shaft of the partial transmissions to a drive shaft. Both partial transmissions drive a common output shaft. During a rocking free operation for rocking the vehicle free, a gear in each respective partial transmission is engaged for driving in opposed primary and secondary directions as specified by the driver. The clutches are alternately engaged and disengaged. For rocking the vehicle free, the clutch of the partial transmission having the gear for driving in the primary direction when engaged, is engaged based on accelerator pedal actuation, and in contrast the clutch of the partial transmission having the gear for driving in the secondary direction when engaged, is automatically engaged if neither of the accelerator or brake pedals has been actuated.

Some embodiments of the present invention provide a control system for a motor vehicle having a first user-operable transmission selector means for selecting a forward operating mode of a transmission corresponding to travel in a forward direction and a reverse operating mode of a transmission corresponding to travel in a reverse direction opposite the forward direction, the control system comprising: a user-operable gear selector configured in a first functional mode to, upon receipt of a user input, select between a plurality of forward direction gear ratios, and wherein the user-operable gear selector is re-configured in a second functional mode to, upon receipt of a user input, select between the forward operating mode and the reverse operating mode.

The present invention relates to a method and device for controlling a vehicle, more particularly, the power train of a compacting machine for earth moving operations, comprising a hydraulic travel pump and a hydraulic travel motor. Control is effected according to a specified control profile when a specified driving operation is to be carried out in that an adjustment of the travel pump is carried out which is independent of the rotational speed of the internal combustion engine. This makes it possible to retain, on the one hand, the rotational speed of the internal combustion engine in the case of abrupt stops of movement or changes in the direction of movement and, on the other hand, to adapt the rotational speed of the engine in the case of somewhat longer uninterrupted pauses between two changes in the traveling behavior, wherein comparatively large fluctuations in the rotational speed are avoided.

A vehicle traveling control apparatus includes a surrounding environment recognition device, a vehicle state recognition device, and a traveling control unit. The surrounding environment recognition device acquires surrounding environment data regarding a vehicle. The vehicle state recognition device acquires state data regarding the vehicle. The traveling control unit executes a traveling control of the vehicle, based on the surrounding environment data and the state data. When the traveling control unit recognizes, based on the surrounding environment data, that the vehicle is parked or stopped in a parking lot and that a road surface in a surrounding region of a parking or stopping position of the vehicle is in a snow accumulation situation, the traveling control unit executes a region generation traveling control that is the traveling control of generating a boarding or alighting region for an occupant of the vehicle in the surrounding region of the parking or stopping position.
