Driving workload estimation
First Claim
Patent Images
1. A method for estimating workload placed on the driver of a vehicle, the method comprising:
- receiving workload estimation data;
detecting driving conditions responsive to said workload estimation data;
calibrating an impact value of at least one of said driving conditions;
combining each said impact value to determine a current driving workload estimate; and
outputting said current-driving workload estimate after the passage of a pre-selected period of time from the outputting of a previous driving workload estimate, wherein said pre-selected period of time varies based on the value of the previous driving workload estimate.

Abstract
A method for estimating workload placed on the driver of a vehicle. The method comprises receiving workload estimation data. Driving conditions responsive to the workload estimation data are detected. An impact value of at least one of the driving conditions is calibrated. The impact values are combined to determine a current driving workload estimate. The current driving workload estimate is output.
