Systems and methods for scheduling driver interface tasks based on driver workload

摘要

A vehicle's dynamic handling state, driver inputs to the vehicle, driver physiological condition, etc. may be examined to determine one or more measures of driver workload. Driver interface tasks may then be delayed and/or prevented from executing based on the driver workload so as to not increase the driver workload. Alternatively, driver interface tasks may be schedule for execution based on the driver workload and caused to execute according to the schedule, for example, to minimize the impact the executing driver interface tasks have on driver workload.

1. A driver interface system for a vehicle comprising:
a system configured to generate tasks; and a processor programmed to (i) monitor over time an activity level of a driver, (ii) determine a variability of the activity level relative to a mean value of the activity level for the driver according to a recursive computation of a determinant of a covariance of the activity level, (iii) determine a driver workload based on the variability, (iv) receive a plurality of driver interface tasks to be executed, and (v) selectively delay or prevent at least some of the plurality of driver interface tasks from being executed based on the driver workload.
