ADAPTIVE STEERING CONTROL FOR A MOTOR VEHICLE
First Claim
1. An adaptive steering control system for a motor vehicle, comprising:
- a sensor adapted to detect a current value of an operation quantity of a steering wheel;
an actor adapted to turn steered wheels; and
a controller adapted to select, according to a speed of the motor vehicle, a map assigning to a detected current value of the operation quantity, a setpoint value of the operation quantity for the actor, and for issuing a setpoint signal to the actor,wherein the controller further is adapted to decide whether the motor vehicle is in a state of motion requiring a high level of attention from a driver and to inhibit a switchover of the map (g1, g2) while the motor vehicle is in a high attention-requiring state.

Abstract
An adaptive steering control system is provided for a motor vehicle. The system includes, but is not limited to a sensor for detecting a current value of an operation quantity of a steering wheel, an actor for turning steered wheels and a controller for selecting, according to the speed of the vehicle, a map (g1, g2) assigning to a detected current value of the operation quantity a setpoint value of the operation quantity for the actor, and for issuing a setpoint signal to the actor. The controller is adapted to decide whether the vehicle is in a state of motion requiring a high level of attention from the driver or not, to inhibit a switchover of the map (g1, g2) while the vehicle is in the high attention-requiring state, and to allow such a switchover while the vehicle is not in the high attention-requiring state.

14. A steering control method for a motor vehicle, comprising the steps of:
-
detecting a current value of an operation quantity of a steering wheel; selecting a map assigning to a detected current value of the operation quantity a setpoint value of the operation quantity; issuing a setpoint signal to an actor of steered wheels, comprising the steps of; deciding whether the motor vehicle is in a state of motion requiring a high level of attention from a driver; if it is decided that the motor vehicle is not in a high attention-requiring state, selecting the map based on a speed of the motor; and if it is decided that the motor vehicle is in a high attention-requiring state, re-selecting the map selected in a previous iteration of selecting the map based on the speed of the motor vehicle.
