1. A method for detecting an attentional state of a driver of a vehicle, the method comprising:
- ascertaining, via an evaluation unit, a lateral deviation of the vehicle from the original lane and a steering angle course; and
ascertaining, via the evaluation unit, at least one attention index as a measure of the attentional state, the attention index including at least one component of the lateral deviation of the vehicle from an original lane and one component of a steering angle correction;
wherein one of the following is satisfied;
(i) the lateral deviation and the steering angle correction are multiplied with one another and each enters into the attention index; and
(ii) components of the lateral deviation and the steering angle correction are added in the attention index.

14. An attentional state detection system, comprising:
-
a lateral deviation detection unit to provide a lateral deviation of a vehicle from an original lane; a steering angle sensor to provide a steering angle; and an evaluation unit to ascertain the lateral deviation of the vehicle from the original lane and a steering angle course, and to ascertain at least one attention index as a measure of the attentional state, the attention index including at least one component of the lateral deviation of the vehicle from the original lane and one component of a steering angle correction; wherein one of the following is satisfied;
(i) the lateral deviation and the steering angle correction are multiplied with one another and each enters into the attention index; and
(ii) components of the lateral deviation and the steering angle correction are added in the attention index. - View Dependent Claims (15, 16, 17, 18, 19, 20)
