Embodiment Construction

[0048] figure 1 A vehicle 10 according to the invention is shown schematically with a power steering system 12 according to the invention.

[0049] The power steering system 12 includes a control module 14 , a steering angle sensor 16 , a steering angle control module 17 and an actuator 18 for generating a force F.

[0050] The vehicle 10 includes a steering rack 20 connected to a steering system 22 . The steering system 22 may be operated by a driver (not shown) via a steering wheel 24 .

[0051] The steering angle sensor 16 monitors the position of the steering wheel 24 and can thus determine the steering angle x of the steering wheel 24 .

[0052] Actuator 18 is, for example, an electric motor, and thus may act on steering system 22 to steer vehicle 10 . In other words, the actuator 18 is capable of producing a movement, in particular a rotational movement of the steering train 22 , by means of the applied force F.

[0053]The control module 14 further includes a driver...

Abstract

A method for operating a power steering system (12) of a vehicle (10) comprises the following steps: a) preparation and / or calculation of a characteristic curve (a), which indicates a power assistance (F1) to be applied by the power steering system (12) as a function of a driver manual torque (M), b) determination of an initial steering angle s (x1) of a steering wheel (24), c) determination of a disturbing force, which acts on a steering train (22) of the vehicle (10) due to external forces, d) compensation for the disturbing force by means of an applied compensating force (F3) in such a way that a steering rack force (F2) at the initial steering angle (x1) assumes an initial value, in particular the initial value zero, ande) application of a synthesized steering rack force (F4) to produce a desired driving feel. A power steering system and a vehicle comprising such a power steering system are furthermore described.

Description

technical field [0001] The invention relates to a method for operating a power steering system of a vehicle, a power steering system for carrying out the method and a vehicle having such a power steering system. Background technique [0002] Modern steering devices in motor vehicles, such as electric power steering (EPS), assist the driver in controlling the vehicle by applying power assist to the vehicle's steering system. In this way, any destructive steering rack forces that occur can be compensated for driver-applied driver manual torque combined with EPS-generated power assist. [0003] Steering rack forces are largely influenced by any lateral forces that occur, but also by road conditions and other factors depending on the current driving situation. [0004] In addition, due to the increasing popularity of driver assistance systems, which can also autonomously intervene in the steering behavior of the vehicle, further contributing factors affecting vehicle handling a...
