Abstract

Various embodiments relating to driving behavior of a driver of a motor vehicle are disclosed. In one embodiment, a method may include assessing driving behavior of the driver according to a comparison of a current value of a coasting characteristic relative to a reference value. The current value may be determined during operation of the motor vehicle. The reference value of the coasting characteristic may be determined from operation of the motor vehicle during at least one past operating phase or another duration. The method further includes displaying a visualization representative of assessed driving behavior of the driver.

Claims

1. A method for assessing a driver'"'"'s ability to coast in a motor vehicle, comprising:

assessing driving behavior of the driver according to a comparison of a current value of a coasting characteristic during operation of the motor vehicle relative to a reference value of the coasting characteristic from operation of the motor vehicle during at least one past operating phase; and

displaying a visualization representative of assessed driving behavior of the driver.

2. The method of claim 1, wherein the coasting characteristic is a coasting distance ratio defined as a ratio of a distance traveled by the motor vehicle while coasting relative to an overall distance traveled by the motor vehicle.

3. The method of claim 2, wherein the reference value is an average coasting distance ratio for a designated duration or a relative maximum coasting distance ratio achieved by the driver for a designated duration.

4. The method of claim 1, wherein the visualization includes a gauge including a current coasting distance ratio, an average coasting distance ratio, and a relative maximum coasting distance ratio achieved by the driver.

5. The method of claim 1, further comprising:

presenting a challenge to the driver, wherein the challenge requires the driving behavior of the driver to manipulate the current value of the coasting characteristic to meet challenge criteria.

6. The method of claim 5, wherein the challenge criteria includes maintaining the current value within a specified range of values or increasing the current value beyond a relative maximum value previously achieved by the driver.

7. The method of claim 1, further comprising:

disregarding the assessed driving behavior of the driver in response to encountering a driver independent interruption of coasting.

8. A method for assessing driving behavior of a driver of a motor vehicle, the method comprising:

determining a current value of a characteristic variable of a coasting strategy carried out during operation of the motor vehicle;

comparing the current value with a reference value; and

assessing the driving behavior of the driver on the basis of the comparison, wherein the reference value is determined from operation of the motor vehicle according to the coasting strategy during at least one past operating phase of the motor vehicle.

9. The method of claim 8, wherein the reference value is repeatedly updated during operation of the motor vehicle.

10. The method of claim 8, wherein the reference value is determined for a specific driver.

11. The method of claim 8, wherein the characteristic variable is a coasting distance ratio defined as a ratio of a distance traveled by the motor vehicle while coasting relative to an overall distance traveled by the motor vehicle.

12. The method of claim 8, wherein the characteristic variable is a coasting time ratio defined as a ratio of an amount of time for which the motor vehicle traveled while coasting relative to an overall time for which the motor vehicle traveled.

13. The method of claim 8, wherein the characteristic variable is a coasting distance.

14. The method of claim 8, wherein a maximum value of the characteristic variable achieved within a specified past time window is used as the reference value.

15. The method of claim 8, wherein the assessment of the driving behavior of the driver takes place depending on the current driving situation or traffic situation, and wherein when determining the characteristic variable, system-induced interruptions of coasting or interruptions of coasting not caused by the driver are disregarded.

16. The method according claim 8, wherein the assessment of the driving behavior of the driver takes place based on an extent to which the characteristic variable for the use of the coasting strategy by the motor vehicle lies within a specified range of values.

17. The method of claim 8, further comprising:

displaying a visualization comparing the current value with the reference value for the driver on a display device.

18. A computing system comprising:

a processor;

a storage device holding instruction that when executed by the processor;

present a challenge to a driver, wherein the challenge requires the driver to manipulate a current value of a coasting characteristic to meet challenge criteria;

assess driving behavior of the driver according to a comparison of the current value of the coasting characteristic determined during operation of the motor vehicle relative to a reference value of the coasting characteristic determined from operation of the motor vehicle during at least one past operating phase; and

display, on a display device, a visualization representative of assessed driving behavior of the driver in relation to meeting the challenge criteria.

19. The computing system of claim 18, wherein the coasting characteristic is a coasting distance ratio defined as a ratio of a distance traveled by the motor vehicle while coasting relative to an overall distance traveled by the motor vehicle, and wherein the reference value is an average coasting distance ratio for a designated duration or a relative maximum coasting distance ratio achieved by the driver for a designated duration.

20. The computing system of claim 18, wherein the visualization includes a gauge including a current coasting distance ratio, an average coasting distance ratio, and a relative maximum coasting distance ratio achieved by the driver.
