SAE Truck and Bus ITS Committee's Driver Interface Task Force Scope Statement: To define a series of methods for interaction, including a messaging structure between the electronic computing systems of a vehicle and the operator of that vehicle. Focus is on the limitations on what interactions are permitted, rather than defining each possible interaction.

Conceptual Framework

Operating Modes 1. Driving Mode  Restricted Software  Determined by Truck Motion and Other Factors  Driving Safety Is Paramount 2. Stopped Mode  Open Computing Environment  Driving Safety Is Not a Factor 3. Diagnostic Mode  Driving Safety is Important  System Diagnosis is Paramount
