A method for assessment of driver behavior 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 behavior during driving, a motor vehicle with the system and a computer program for performing the process.

1. A method for assessment of driver behavior during driving of a vehicle, the method being performed by an electronic control unit and comprising the steps of: continuously characterising a driver's chosen braking processes as a basis for said assessment based on first data from at least one first sensor recording the chosen braking processes;determining a cause of a chosen braking process based on at least one of second data from at least one second sensor, the second data being sensed during the chosen braking process, and on third data recorded prior to the chosen braking process; andassessing whether the chosen braking process is an appropriate response to the cause determined,the chosen braking process being characterised based on whether, and to what extent, auxiliary brakes, service brakes and engine brakes of the vehicle were used during the chosen braking process, the assessment of whether the chosen braking process is the appropriate response being based on the effect of the chosen braking process on fuel consumption and traffic safety. 2. The method according to claim 1, in which the step of determination of the cause involves the use of camera means. 3. The method according to claim 1, in which the step of determination of the cause involves the use of map data and vehicle location determination means. 4. The method according to claim 1, in which the step of determination of the cause involves using means for recording of evasive maneuvers of the vehicle. 5. The method according to claim 1, further comprising the step of continuously determining driving conditions in which the vehicle is driven and taking the driving conditions into account in the assessment. 6. The method according to claim 1, in which the step of determination of the cause involves the use of means for determining road state characteristics. 7. A system for assessment of driver behavior during driving of a vehicle, comprising means for continuously characterising the driver's chosen braking processes as a basis for the assessment,means for determining a cause of a chosen braking process, andmeans for assessing whether the chosen braking process is an appropriate response to the cause determined,the chosen braking process being performed by at least one of: auxiliary brakes, service brakes and engine brakes of the vehicle, the assessment of whether the chosen braking process is the appropriate response being based on the effect of the chosen braking process on fuel consumption and traffic safety. 8. The system according to claim 7, in which the means for determination of the cause comprise camera means. 9. The system according to claim 7, in which the means for determination of the cause comprise a map information unit for supplying map data and comprise a vehicle location determination means. 10. The system according to claim 7, in which the means for determination of the cause comprise means for recording of evasive maneuvers. 11. The system according to claim 7, further comprising means for continuously determining conditions under which the vehicle is driven, and the conditions are taken into account in the assessment. 12. The system according to claim 7, in which the means for determination of the cause comprise means for determining road state characteristics. 13. A vehicle provided with the system according to claim 7. 14. A non-transitory computer-readable medium on which is recorded a computer program for assessment of driver behavior during driving of a vehicle, the program comprising program code which, when run by an electronic control unit or another computer connected to the electronic control unit, enables the electronic control unit to perform the steps of: continuously characterising a driver's chosen braking processes as a basis for said assessment based on first data from at least one first sensor recording the chosen braking processes;determining a cause of a chosen braking process based on at least one of second data from at least one second sensor, the second data being sensed during the chosen braking process, and on third data recorded prior to the chosen braking process; andassessing whether the chosen braking process is an appropriate response to the cause determined,the chosen braking process being characterised based on whether, and to what extent, auxiliary brakes, service brakes, and engine brakes of the vehicle were used during the chosen braking process, the assessment of whether the chosen braking process is the appropriate response being based on the effect of the chosen braking process on fuel consumption and traffic safety.
