SYSTEMS AND METHODS FOR ANALYZING VERTICAL FORCE ON A STEERING COLUMN FOR DETERMINING OPERATOR VIGILANCE
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.
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.
