Embodiment Construction

[0040] figure 1 A flowchart 30 for implementing a method for steering a vehicle according to an exemplary embodiment of the invention is shown schematically.

[0041] After starting, the operating state of the vehicle is first determined in a first method step 31 . If the vehicle is stationary, the spring travel is then determined in a second method step 32 taking into account different chassis settings, and finally in a third method step the steering stop is maximized and scaled as a function of the respective spring travel. output.

[0042] This makes it possible to provide the driver with the smallest possible turning trajectory or turning radius when maneuvering in tight spaces or when parking in a garage.

[0043] If the vehicle is moving, the steering stop is adapted in the next step. First, the deflection angle is determined in a fourth method step 34 . If the deflection angle is equal to zero, the deflection stop can remain unchanged in the next fifth method step 3...

Abstract

A method is provided for vehicle steering using a steering actuation apparatus operable by the driver. The vehicle steering device has electromechanical control assemblies for this purpose for controlling a steerable wheel, located on the right and left on a vehicle body, of a wheel pair of at least one steerable vehicle axis. A central control unit compares target value specifications of the steering actuation apparatus to ESP specifications and actual values of the wheel positions of the steerable wheels and adapts electronic specifications of the steering stops for the steerable wheels to the operating situations of the vehicle.

Description

technical field [0001] The invention relates to a method for steering a vehicle by means of a driver-operable steering device. For this purpose, the vehicle steering system has an electromechanical adjustment unit for controlling the wheels of at least one steerable axle pair of steerable wheels on the right and left side of the vehicle body. A central control unit compares the nominal preset value of the steering with the ESP (Electronic Stability Program or Electronic Stability Program) preset value and the actual value of the wheel position of the steerable wheels. Background technique [0002] For this purpose, from the patent document DE 101 14 600 A1 a vehicle steering unit and an axle steering module for the vehicle steering unit are known, the vehicle steering unit has a steering control device, in particular a steering wheel, and each has a steering wheel for controlling the steering wheel. The pairs of wheels that steer the axle are located on the right and left s...
