Description

Technical area

The present invention relates to providing an evaluation of the driving behavior of a driver, in particular a driving student, following a training trip.

State of the art

In preparation for the driver's license exam, a learner usually completes some driving lessons in which he travels under supervision. After completing a driving lesson, the trainee driver usually receives feedback from the driving instructor, in which he may describe a certain traffic situation as well as the behavior of the trainee in the relevant traffic situation. However, such a description is often inaccurate, so that the learner often can not accurately match the situation described to their own driving behavior and thus the desired effect of the feedback, namely an improvement of the driving behavior of the student, in many cases fails.

In an application "BMW Track My Ride" the route of a training run is recorded. While driving a driving instructor, the driving behavior of a student according to predetermined criteria, such. For example, "adjusted speed", "distance to other road users", "observation of traffic / mirror vision" and "safe overtaking", evaluate with "-" or "+". Furthermore, the driving instructor has the opportunity to confirm the completion of training content. For this, the learner driver can receive awards that he can share with others in a social network. Other passengers also have the opportunity to supplement the driving behavior assessment with information on other criteria, such as: B. "feel-good factor", "concentration", "serenity" and "confidence in the driver".

From the publication DE 199 14 672 A1 A method for storing a plurality of driving situations of a driving school vehicle operated by a learner driver under the supervision of a driving instructor in a storage medium is known. In particular, information about incorrect operation of the driving school vehicle, instructions and / or comments of a driving instructor, sensor values of one or more sensors present in the driving school vehicle and, for example, position data obtained via a GPS receiver can be stored.

From the publication US 2010/0208070 A2 For example, a method and a system for collecting driver-related information by a mobile computing unit are known. The system is intended for use by a driving instructor in a driving school vehicle. The portable computing unit communicates with one or more cameras for recording a traffic event in a vehicle environment and with a position sensor for providing position information about the geographical position of the motor vehicle. The arithmetic unit records the information thus acquired in order to obtain a sequence of traffic situations along a traveled route. Furthermore, a driving instructor can enter ratings of a driving behavior of the driving student, which are assigned to the current position of the motor vehicle. In addition, by suitable sensors, the vehicle acceleration or deceleration, the speed of the engine and the operation of controls along the route can be detected and stored depending on the geographical position of the motor vehicle. On a display of the mobile computing unit, a map section with the traveled route can be displayed, with driving events can be marked on the relevant position of the route on the map.

It is an object of the present invention to provide a method and an apparatus by means of which a comprehensive and position-related recording of the driving behavior of a driving student, including an assessment by a driving instructor, is possible. In particular, the learner should be allowed to make an assessment of their own driving skills after completing a training session.
