Method and device for evaluating a driving style
First Claim
1. A method for evaluating a driving style, the method comprising the acts of:
- continuously sensing a current driving state by reference to associated driving state parameters and continuously sensing a current traffic situation by reference to associated traffic situation parameters;
determining an associated reference driving state in relation to a respectively sensed current traffic situation using a predefinable traffic situation reference driving state relation, the associated reference driving state representing a desirable driving state in a respective traffic situation with respect to a predefinable evaluation criterion;
evaluating the sensed current driving state by comparison with the respectively associated reference driving state in accordance with the predefinable evaluation criterion;
outputting one or more acknowledgment information items relating to a driving style during a respective preceding traffic situation, wherein at least two groups of the acknowledgement information items associated with two different values of a predefinable category parameter are predefined as driving style acknowledgement information items available for output; and
wherein an acknowledgment generation criterion is predefined such that an amount of acknowledgment information items of one of the two groups output during a journey remains larger than an amount of acknowledgment information items of another of the two groups which are output, or an amount of acknowledgment information items of the one group which are output has a predefinable relationship with that of the other group.

Abstract
The invention relates to a method and to a device for evaluating driver performance, comprising the continuous detection of the actual state of travel and the actual traffic situation and determining a reference state of travel pertaining to the actual traffic situation. Said reference state of travel is the state of travel desired in the respective traffic situation according to a predetermined evaluation criterion. According to the invention, the actual state of travel detected is evaluated according to said evaluation criterion by comparing it with the pertaining detected reference state of travel. Subsequently, one or more pieces of feedback information regarding driver performance during a preceding traffic situation are given. The invention also refers to the use of the inventive device for the instructive evaluation of the driver performance of road vehicle users.
