Steering system with front axle steering and rear axle steering system and method for controlling such a steering system

摘要

The present invention relates to a steering system with front axle steering system (12) and rear axle steering system (14) and a method for controlling such a steering system. It is the object of the invention, a steering system for a motor vehicle (10) with a front axle steering system (12), a power-assisted steering device for the front axle steering system (12), a rear axle steering system (14) and a monitoring device for monitoring the operability of the power-assisted steering device with an improved safety, to make available. For the same purpose, a method for controlling a steering system in order to be made available. According to the invention, a steering system for a motor vehicle (10) comprises• a front axle steering system (12) with a power-assisted steering device,• a rear axle steering system (14),• a monitoring device for monitoring the operability of the power-assisted steering device as well as• a control device, which, with at least one means for adjusting the maximum steering angle at the rear axle steering system (14) is in functional connection, and is configured in such a way that the maximum steering angle at the rear axle steering system (14) is increased, if the monitoring device detects a limited operability of the power-assisted steering device.
