An apparatus for controlling an MDPS system may include an MDPS-basic logic unit determining a first auxiliary command current for driving an MDPS motor in a manual driving mode, based on column torque applied to a steering column of a vehicle and a vehicle speed, an autonomous driving steering controller determining a second auxiliary command current for driving the MDPS motor in an autonomous driving mode, and a mode change controller determining a driver's steering intervention using a variable reference time variably determined based on the column torque in the manual driving mode, determining a mode change time from the autonomous driving mode to the manual driving mode based on the column torque, and determining a final auxiliary command current for driving the MDPS motor upon mode change, by applying, to the first and second auxiliary command currents, a weight into which the mode change time is incorporated.

A method and device for controlling a rear-axle steering system, in particular a rear-axle steering system of a motor vehicle, determines a current physical condition of the rear-axle steering system on the basis of a detected current operating state and a pre-determined reference operating state of the rear-axle steering system. The method defines a maximum permissible steering angle of the rear-axle steering system depending on the estimated physical condition of the rear-axle steering system and depending on at least one of the operating parameters of driving speed, steering angle and steering angle speed of the vehicle, and actuates the rear-axle steering system such that the steering angle of the rear-axle steering system does not exceed the assigned defined maximum permissible steering angle for the current operating parameter(s) of the vehicle.

This application describes systems and techniques for adjusting one or more setting(s) of a vehicle based on detected condition(s) to avoid damage due to contact of the tires with a body, chassis, or other components of the vehicle. In some instances, the vehicle may determine a ride height of the vehicle, determine a limited range of steering angles based at least in part on the ride height, and control operation of the steering system of the vehicle based at least in part on the limited range of steering angles. In some instances, the vehicle may determine a steering angle of the vehicle, determine a limited range of ride heights based at least in part on the steering angle, and control operation of the suspension system of the vehicle based at least in part on the limited range of ride heights.

A steering system for an automated driving process of a motor vehicle having at least one steering controller, a power electronics unit, apparatus for adjusting a steering angle, and an electric motor. The steering system includes a steering controller which generates steering control commands dependent on the data of a surroundings sensor system. The steering control commands are converted into actuation signals for the electric motor by the power electronics unit, and the electric motor then actuates the apparatus for adjusting the steering angle. The steering controller generates a current steering control command and at least one future steering control command dependent on the data of the surroundings sensor system and transmits the steering control commands to the power electronics unit.

A railless tugger train (100) includes a train module (10), at least one transportation module and at least two axis modules, wherein each axis module has a stiffly configured axis beam, at which a first mounting device is configured in the form of a stiff mounting of the train module or a transportation module and at which a second mounting device is configured for an articulated connection of a transportation module. At least two wheels (19) are mounted at the axis beam in such a way that the wheels are each rotatable around a rotation axis (D) which is configured vertical to the longitudinal axis (L) of the axis beam.

A motor vehicle has a control device, a first sensor and a global positioning device. The control device has a control unit and a data memory. At least one item of information about an arrangement of an overhead line is stored on the data memory. The control unit is connected to the first sensor and to the global positioning device. The first sensor determines a position of the overhead line relative to the motor vehicle and provides the control unit with the relative position. The global positioning device determines a global position of the motor vehicle and provides the control unit with it. The control unit, on the basis of the established relative position, the established global position and the information about the arrangement of the overhead line, calculates a position of the motor vehicle.

The present invention relates to a method for controlling the position of a vehicle to ensure stable position of a vehicle against tilting due to a rapid change in vehicle speed. The method includes: determining whether a vehicle speed is rapidly changing in a straight direction on the basis of an extent of depression of a pedal that changes a position of a steering wheel and a change in vehicle speed; determining whether the vehicle is tilting on the basis of a change in a yaw-rate by means of the controller when the vehicle speed is rapidly changing in the straight direction; and providing compensation torque in the direction opposite the direction in which the vehicle is tilted by operating a steering motor when the controller determines that the vehicle is tilting.
