What are the three major components of the Driving Task Model?

• A. Perception, Decision, Action
• B. Sensing, Analysis, Execution
• C. Control, Guidance, Navigation
• D. Planning, Execution, Observation

Answer: (C)

Understanding the Driving Task Model means seeing how driving work is organized into three interrelated activities that translate a driver’s intentions into vehicle motion. The high-level function is navigation, where you plan the route, anticipate what lies ahead, and decide when to make maneuvers like lane changes or exits. The mid-level function is guidance, which turns that plan into a safe path on the road—keeping the vehicle in the right lane, maintaining a safe following distance, and adjusting to curves, ramps, or traffic flow. The low-level function is control, the actual manipulation of the vehicle’s actions—steering, throttle, braking, and gear changes—to execute the guidance precisely and maintain stability.

So, navigation sets the goals and route, guidance shapes the path you want the vehicle to follow, and control implements the exact motor actions needed to stay on that path, adapting in real time to changes on the road. This trio is what makes the Driving Task Model distinct from descriptions that focus only on perception or decision or execution in isolation.
