Problems solved by technology

Due to the variety of assessments, the worst-case scenario needs to be assumed, that is, any limitation in the presence of error must result in the most critical situation, or even the most dangerous evaluation
As a result, the performance of the possible electric assist cannot be fully exploited

Embodiment Construction

[0038] The device according to the invention and the method according to the invention are described in detail below with reference to the drawings.

[0039] figure 1 The device according to the invention is shown in the form of a block diagram. The device comprises a memory device 1 which stores a definition of an admissible steering angle variation range based on a driver's desired steering angle variation. In the embodiment shown, the memory means actually stores a plurality of definitions for determining the permissible range of steering angle variation at different vehicle speeds in each case based on the driver's desired steering angle variation. This definition can be stored in the memory device in a graphical format and / or by means of functional associations. The definition of the permissible range of steering angle variation based on the driver's desired steering angle variation can be stored in the form of a value range for each steering angle variation desired by ...

Abstract

A method and apparatus for limiting assisting steering torque in a steering system having electronic power assisted steering is provided. In accordance with the method and apparatus, a steering angle change desired by the driver is determined and a range of valid steering angle changes dependent upon the steering angle change desired by the driver are defined. Subsequently it is determined whether a current steering angle change is included in the range of valid steering angle changes, and if the current steering angle change is not included in the range of the valid steering angle changes, the assisting steering torque is limited.

Description

technical field [0001] The invention relates to a method for limiting the assist steering torque of an electrically assisted steering system. The invention also relates to a device for carrying out the method. Background technique [0002] In addition to providing traditional servo assist to the driver, modern steering systems also include electric power steering. Electric power steering presents the possibility, for example, to superimpose steering torque for the driver within the scope of assistance systems, which increases comfort and safety. In addition, electric power steering makes it possible to reduce the disturbing influence of the torque transmitted from the vehicle or the road to the steering wheel. Servo assist is defined in this context as a torque superposition system that is based on and augments the driver's manual torque. Electric power assist is generally independent of driver manual torque and may even counteract driver manual torque in order to provide...
