Driver attention evaluation
First Claim
Patent Images
1. A driver evaluation system for a vehicle comprising:
- a controller programmed to generate for display a parameter indicative of a driver'"'"'s level of attention to driving the vehicle for a sliding window time period based on a complement of a weighted average of a plurality of counts at least some of which represent a number of interaction events between the driver and an infotainment system in the vehicle during the time period.

Abstract
A driver evaluation system for a vehicle generates for display a parameter indicative of a driver'"'"'s level of attention to driving the vehicle for a temporal period based on a complement of a weighted average of a plurality of counts. Some of the counts represent a number of interaction events between the driver and an infotainment system in the vehicle during the temporal period.

8. A driver evaluation method comprising:
by a controller, accumulating a driver inattention event count such that, in response to occurrence of an inattention event and a count timer exceeding a limit, the count timer is decreased according to a difference between the count timer and a quotient of the limit and the count, and displaying a driver attention state value that is based on a complement of a weighted average that includes the count. - View Dependent Claims (9, 10, 11, 12, 13)

14. A vehicle comprising:
-
an interface; and one or more controllers programmed to, in response to a driver attention request, generate for display via the interface a parameter indicative of a driver'"'"'s level of attention to driving the vehicle for a selected time period based on a complement of a weighted average, having a value between zero and one, of a plurality of counts at least some of which represent a number of interaction events between the driver and an infotainment system in the vehicle during the selected time period, and accumulate one of the counts such that, in response to occurrence of an interaction event, the one of the counts being greater than zero, and a value of a count timer exceeding a predefined time limit, the value is decreased according to a difference between the count timer and a quotient of the predefined time limit and the one of the counts. - View Dependent Claims (15, 16, 17)
