Abstract

System, methods, and other embodiments described herein relate to vigilance evaluator. In one embodiment, a method includes receiving a vertical force measurement based on a force sensor attached to a steering column; and estimating a level of operator vigilance based on the vertical force measurement.

Claims (28)

1 . A method, comprising:

receiving a vertical force measurement based on a force sensor attached to a steering column; and

estimating a level of operator vigilance based on the vertical force measurement.

2 . The method of claim 1 , further comprising adjusting the vertical force measurement based on a movement of a vehicle.

3 . The method of claim 1 , wherein estimating the level of operator vigilance is further based on a driver profile.

4 . The method of claim 1 , wherein the the force sensor is at least one of a strain gauge sensor, a load cell sensor, or a piezoelectric sensor.

5 . The method of claim 1 , wherein the force sensor is further attached to a steering wheel.

6 . The method of claim 1 , wherein estimating the level of operator vigilance is further based on at least one of time, weather, or traffic conditions.

7 . The method of claim 1 , further comprising generating a notification or takeover request based on the level of operator vigilance estimated.

8 . The method of claim 1 , wherein receiving the vertical force measurement based on the force sensor further includes wherein the vertical force measurement is obtained from a predictive model applied to vehicle sensor data.

9 . A system, comprising:

a processor; and

a memory communicably coupled to the processor and storing machine-readable instructions that, when executed by the processor, cause the processor to:

receive a vertical force measurement based on a force sensor attached to a steering column; and

estimate a level of operator vigilance based on the vertical force measurement.

10 . The system of claim 9 , wherein the machine-readable instructions further include an instruction that, when executed by the processor, cause the processor to adjust the vertical force measurement based on a movement of a vehicle.

11 . The system of claim 9 , wherein to estimate the level of operator vigilance is further based on a driver profile.

12 . The system of claim 9 , wherein the the force sensor is at least one of a strain gauge sensor, a load cell sensor, or a piezoelectric sensor.

13 . The system of claim 9 , wherein the force sensor is further attached to a steering wheel.

14 . The system of claim 9 , wherein to estimate the level of operator vigilance is further based on at least one of time, weather, or traffic conditions.

15 . The system of claim 9 , wherein the machine-readable instructions further include an instruction that, when executed by the processor, cause the processor to generate a notification or takeover request based on the level of operator vigilance estimated.

16 . A non-transitory computer-readable medium including instructions that when executed by one or more processors cause the one or more processors to:

receive a vertical force measurement based on a force sensor attached to a steering column; and

estimate a level of operator vigilance based on the vertical force measurement.

17 . The non-transitory computer-readable medium of claim 16 , wherein the non-transitory computer-readable medium further includes an instruction that, when executed by the one or more processors, causes the one or more processors to adjust the vertical force measurement based on a movement of a vehicle.

18 . The non-transitory computer-readable medium of claim 16 , wherein to estimate the level of operator vigilance is further based on a driver profile.

19 . The non-transitory computer-readable medium of claim 16 , wherein the the force sensor is at least one of a strain gauge sensor, a load cell sensor, or a piezoelectric sensor.

20 . The non-transitory computer-readable medium of claim 16 , wherein the force sensor is further attached to a steering wheel.
