Embodiment Construction

[0035] figure 1 An exemplary steering system 32 is shown in perspective view. In the present case, steering system 32 is designed as an electrically assisted steering system and therefore has an electrically assisted power assist. Furthermore, steering system 32 is provided for use in a vehicle (not shown), in particular a motor vehicle. In the installed state, the steering system 32 has an operative connection to the wheels 34 of the vehicle and is provided for influencing the direction of travel of the vehicle. Alternatively or additionally, however, it is also conceivable for the steering system to be designed with electric superposition steering and / or external force steering.

[0036] Steering system 32 includes a steering device. The steering device has a steering gear 36 which in the present case is designed as a known rack-and-pinion steering gear. The steering gear 36 includes a steering pinion 38 and a rack 40 mechanically coupled to the steering pinion 38 . Ste...

Abstract

The invention relates to a method for operating a steering device which comprises at least one electric motor (10) that can be operated with an increased torque lying between a nominal torque (14) ofthe electric motor (10) and a maximum torque (16) of the electric motor (10) over an entire basic setting range (12). In at least one operating state, a threshold torque (18) of the electric motor (10) is at least temporarily limited to a reduced torque (20), in particular in comparison to the maximum torque (16), at least depending on at least one temperature characteristic variable.

Description

technical field [0001] The invention relates to a method for operating a steering system according to claim 1 . [0002] Furthermore, the invention relates to a steering device according to claim 12 and a control unit according to claim 13 . Background technique [0003] Steering systems are known from the prior art with electric motors, for example for providing steering support and / or additional steering angles. The electric motors used here are usually fixedly preset and can only be selected from a small group of available electric motors, so that the electric motors cannot therefore be replaced arbitrarily. Furthermore, the electric motor has a predetermined torque range, which is nominally designed for a defined operating point of the electric motor. In steering systems, this operating point generally corresponds to a state in which the electric motor must deliver its full torque when the motor shaft is stationary, for example when turning toward a curb. [0004] The...
