Abstract: A control apparatus for an all-wheel drive vehicle that includes (i) a power source, (ii) a power distribution device for distributing a power from the power source to front and rear wheels, (iii) a differential limiting mechanism for placing the power distribution device in a differential limiting state in which a rotational difference between the front wheels and the rear wheels is limited, and (iv) a braking device for applying a wheel braking torque to each of the front and rear wheels. When the power distribution device is placed in the differential limiting state and the wheel braking torque is applied to each of the front wheels and the rear wheels, a torque limiting control is executed for setting an upper limit value of a torque of the power source to a smaller value when the wheel braking torque is large than when the wheel braking torque is small.

Abstract: A method for classifying an underlying surface travelled by an agricultural utility vehicle includes acquiring a detail of a surface of the underlying surface in the form of optical data, classifying the optical data in a data processing unit with respect to different underlying surface classes, and determining an underlying surface class on the basis of the classifying step. Output data is output from the data processing unit representative of the determined underlying surface class as a classification result. A technical feature of the utility vehicle is adapted as a function of the classification result.

Abstract: A vehicle includes a left clutch provided on a path for transmitting driving torque to a left rear wheel and a right clutch provided on a path for transmitting driving torque to a right rear wheel torque. If a command value of the driving torque distributed to the left rear wheel using the left clutch and a command value of the driving torque distributed to the left rear wheel using the right clutch fall respectively below predetermined lower limit values, a control device controls the command values of the driving torque to be predetermined lower limit values. While realizing an optimal torque distribution control, accuracy of the driving torque distributed to the left and right rear wheels (auxiliary drive wheels) can be improved by preventing the command values (command torque) distributed to the left and right rear wheels from becoming small below the limit.

Abstract: A vehicle includes a sensor device monitoring at least one collision region that is located in the surroundings of the vehicle for sensing at least one object that enters and/or is present in a possible collision region during motion of the vehicle; an electromechanical brake booster and braking force-regulating components coupled thereto, which are operationally integrated into a vehicle braking system for decelerating the vehicle; and a control device that receives signals from the sensor device and, on the basis of those signals, controls the brake booster and the braking force-regulating components and/or further active chassis components. A method for avoiding a collision between the vehicle and the at least one object includes, upon sensing the at least one object, modifying a driving speed and/or driving direction of the vehicle, with the aid of the control device in combination with the braking system and the braking force-regulating components.

Abstract: A vehicle control strategy provides for automatically controlled movement from rest with deliberate wheel slip to maximize thrust. Different wheel slip conditions are provided for different terrain types. Wheel slip may be progressively reduced as the vehicle reaches a steady state speed. The strategy may also be implemented to maintain vehicle progress on low friction surfaces. The vehicle driver may be commanded to vary a control input, such as accelerator pedal position.

Abstract: In a method for controlling a vehicle with a drive system comprising a power unit configuration adapted to provide output for the vehicle's operation, and further comprising a planetary gear and a first and second electrical machine, connected to components in the planetary gear via their rotors, a locking means is moved from a locked position, in which two of the planetary gear's components are locked together, so that the three components of the planetary gear rotate with the same speed, to a release position, when the vehicle is driven with the locking means in a locked position, by carrying out the following method steps. The power unit configuration is controlled in order to achieve torque balance between the components that are locked together by the locking means, and such locking means are moved into a release position, when said torque balance prevails.

Abstract: In a method for controlling a vehicle with a drive system comprising a power unit configuration adapted to provide power for the vehicle's operation, and further comprising a planetary gear and a first and second electrical machine, connected to components in the planetary gear via their rotors, a locking means is moved from a release position, in which the planetary gear's components are free to rotate independently of each other, to a locked position, in which two of the planetary gear's components are locked together, so that the three components in the planetary gear rotate with the same speed. The power unit configuration is controlled in order to achieve a synchronous, or substantially synchronous, rotational speed between the input and output shaft of the planetary gear, and the locking means are then moved to the locked position.

Abstract: This control device is applied to a hybrid vehicle that is provided with a motor lock mechanism that changes over the state of a power distribution mechanism between a differentiating state in which a differentially rotating state between an engine and a first motor-generator is permitted, and a non-differentiating state in which the rotation of the first motor-generator is prohibited. The control device stops combustion by the engine and changes over to an EV mode when predetermined conditions become valid during implementation by the power distribution mechanism of a differentiating mode of the differentiating state or of a non-differentiating mode of the non-differentiating state. The condition is set to be more severe while the non-differentiating mode is being implemented, as compared with the case while the differentiating mode is being implemented.
