Abstract

A method for assessment of driver behaviour during driving by continuously characterizing (S1) the driver'"'"'s braking processes by determining (S2) the cause of a chosen braking process such as a camera view, map and location data, evasive maneuvers, ambient conditions, road conditions, and assessing (S3) whether the chosen braking process is the appropriate response. Also a system for assessment of driver behaviour during driving, a motor vehicle with the system and a computer program for performing the process.

Claims

1. A method for assessment of driver behaviour during driving of vehicles, comprising the step of continuously characterising (S1) the driver'"'"'s chosen braking processes as a basis for said assessment, characterised by the steps of determining (S2) the cause of a chosen braking process and assessing (S3) whether the chosen braking process is the appropriate response to said cause determined.

2. A method according to claim 1, in which said braking process is characterised in terms of auxiliary brakes, service brakes and engine brakes.

3. A method according to claim 1 or 2, in which the step of determination of causes involves the use of camera means (112).

4. A method according to claim 1 or 2, in which the step of determination of causes involves the use of map data and vehicle location determination means (114b).

5. A method according to any one of claims 1-4, in which the step of determination of causes involves using means (116) for recording of evasive manoeuvres.

6. A method according to any one of claims 1-5, further comprising the step of continuously determining conditions in which the vehicle is driven, which conditions are taken into account in said assessment.

7. A method according to any one of claims 1-5, in which the step of determination of causes involves the use of means (119) for determining road state characteristics.

16. A computer programme (P) for assessment of driver behaviour during driving of vehicles, which programme (P) comprises programme code which, when run by an electronic control unit (100) or another computer (500) connected to the electronic control unit (100), enables the electronic control unit (100) to perform steps according to claims 1-7.

17. A computer programme product comprising a digital storage medium which stores the computer programme according to claim 16.

8. A system (I) for assessment of driver behaviour during driving of vehicles, comprising means (100) for continuously characterising the driver'"'"'s chosen braking processes as a basis for said assessment, characterised by means (100, 110, 120, 130) for determining the cause of a chosen braking process and means (100, 110, 120, 130) for assessing whether the chosen braking process is the appropriate response to said cause determined.

9. A system according to claim 8, in which said braking process is characterised in terms of auxiliary brakes, service brakes and engine brakes.

10. A system according to claim 8 or 9, in which said means for determination of causes comprise camera means (112).

11. A system according to claim 8 or 9, in which said means for determination of causes comprise a map information unit (114a) for map data and vehicle location determination means (114b).

12. A system according to any one of claims 8-11, in which said means for determination of causes comprise means (116) for recording of evasive manoeuvres.

13. A system according to any one of claims 8-12, further comprising means (118) for continuously determining conditions in which the vehicle is driven, which conditions are taken into account in said assessment.

14. A system according to any one of claims 8-13, in which said means for determination of causes comprise means (119) for determining road state characteristics.

15. A vehicle (1) provided with a system (I) according to any one of claims 8-14.
