1. A method for determining when a task may be performed on a vehicle, the method comprising:
- generating a driver workload value based on at least one task parameter describing a predetermined attribute of the task, the predetermined attribute comprising a task status parameter comprising a measure of how recently the task has been initiated; and
preventing a user from performing the task if the driver workload value exceeds a predetermined driver workload threshold and the vehicle is moving.

Abstract
Methods and apparatus are provided for determining when a task may be performed on a vehicle that is moving. The method includes generating a driver workload value based on at least one task parameter describing a predetermined attribute of the task and preventing a user from performing the task if the driver workload value exceeds a predetermined driver workload threshold and the vehicle is moving.

10. A system for determining when a task may be performed on a vehicle, the system comprising:
-
a user interface for receiving input from a user of the vehicle; a processor coupled to the user interface and configured to; generate a driver workload value in response to input from the user, wherein the driver workload value is based on at least one task parameter describing an attribute of the task and at least one vehicle parameter describing an attribute of the vehicle parameter, the attribute of the task comprising a task status parameter comprising a measure of how recently the task has been initiated; and lock-out the task if the driver workload value exceeds a predetermined driver workload threshold and the velocity of the vehicle exceeds a predetermined velocity threshold. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)

18. A method for determining when a user of a vehicle may perform a task on a user interface, the method comprising:
-
determining a value of at least one task parameter that describes an attribute of the task; determining at least one vehicle parameter that describes an attribute of the vehicle; determining at least one environment parameter that comprises an attribute of an environment surrounding the vehicle; generating a driver workload value, wherein the driver workload value is a function of the at least one task parameter, the environment parameter, and the at least one vehicle parameter; and locking-out the task if the driver workload value exceeds a predetermined driver workload value and the velocity of the vehicle exceeds a predetermined velocity threshold; wherein the at least one task parameter comprises a task status parameter, a task type parameter, and a task structure parameter and the step of determining further comprises; determining the value of the task status parameter based on the current status of the task, wherein the current status of the task is one of a newly initiated status, a pending status, a terminated status, and a complete status; determining the value of the task type parameter based on a task type that corresponds to the task, wherein the task type is one of a menu-selection task type, a list-selection task type, and an alphanumeric keypad task type; and determining the value of the task structure parameter based on a predetermined attribute of the structure of the task. - View Dependent Claims (19)
