AI Technical Summary

Technical Problem

Existing vehicle control systems require complex and risky direct manipulation of rear axle steering through the conventional steering wheel, leading to driver strain and potential operator errors.

Method used

A system with a steering wheel and an additional control unit, such as displacement-sensitive paddles, allows the driver to input a desired target lateral speed, which is processed through a mathematical vehicle model to control both front and rear axle steering systems independently.

Benefits of technology

Enables decoupled, superimposed vehicle movements, reducing steering effort and operator risk, allowing confident maneuvers like lane changes and parking with reduced space requirements and maintaining familiar steering feel.

Abstract

The invention relates to a system (1) for controlling a vehicle (2) which has a front axle steering system (StbW) and a rear axle steering system (RAS) and a control unit designed as a steering wheel (3) for controlling the vehicle (2).According to the invention, the system (1) comprises: - a further operating unit (4) for controlling the vehicle (2), which is designed and configured for operation by a driver of the vehicle (2) and for inputting a desired target lateral speed (VQS) of the vehicle (2) by this operator, and - a control unit (5), which is designed and configured to receive the desired target lateral speed (VQS) from the further operating unit (4) and at least one state variable of the vehicle (2) and to calculate, using a predetermined mathematical vehicle model, a lateral force (FS) and a yaw moment (GM) acting on the vehicle (2) at the desired target lateral speed (VQS), and to use the calculated lateral force (FS) and the calculated yaw moment (GM) to control the front axle steering (StbW) and the rear axle steering (RAS) in such a way that the desired target lateral speed (VQS) of the vehicle (2) is achieved.Furthermore, the invention relates to a vehicle (2) with this system (1) and a method for controlling the vehicle (2).
