ADAS & Vehicle Networks
Understand how modern vehicles detect their surroundings, communicate between modules, warn drivers, and sometimes intervene. Begin with the big picture, then test the idea in an interactive lab.
The three big ideas
01 · Sense
Cameras, radar and other sensors supply information about the environment and vehicle.
02 · Decide
Electronic control modules process inputs and determine whether to inform the driver or request a response.
03 · Act
Depending on the feature and conditions, the system may display a warning, adjust speed, steer or apply brakes.

What Is ADAS?
ADAS stands for Advanced Driver Assistance Systems. These are vehicle technologies designed to assist the driver in certain driving tasks. They do not automatically make a vehicle self-driving.
Follow the information
Imagine driving toward slower traffic:
- Input: A forward-facing sensor detects an object ahead.
- Processing: A module evaluates relative speed, distance and other signals.
- Output: It may warn the driver, and an equipped system may request automatic braking.
- Feedback: The vehicle keeps updating sensor information as the situation changes.
Know the difference
Forward Collision Warning (FCW) alerts the driver to a potential frontal collision. Automatic Emergency Braking (AEB) may apply the brakes when its activation criteria are met.
Feature names, detection limits, interventions and required driver actions vary by manufacturer, model, equipment and conditions.
Forward Collision: Warning vs. Braking
Set your speed, the lead vehicle's speed, initial gap and road condition. Run the scenario and watch a simplified detection → warning → braking sequence. Use Brake now to compare driver action against automatic intervention.

*Time to collision assumes current relative speeds remain unchanged; ∞ means the gap is not currently closing.
Safety boundary: This is a teaching analogy. Actual FCW/AEB behavior depends on vehicle design, sensor health, object recognition, speeds, traction, driver input and other conditions. Never use this demo to set calibration targets, validate a repair or predict a real vehicle's stopping distance.
Three quick questions
1. Which statement best describes ADAS?
2. In this lesson, which feature can request braking?
3. The forward sensor detects an object, but a warning does not appear. What should a technician investigate?
