ADAS or Advanced Driver-Assistance Systems Required in Cars by 2026

An overview of ADAS, or Advanced Driver-Assistance Systems, that will be mandatory in cars by 2026.

ADAS, or Advanced Driver-Assistance System, is an intelligent driving aid installed in many new car models to make driving easier. Let's look at the ADAS features that will be required in new cars in 2026.

1. Collision Avoidance Systems

• AEB (Autonomous Emergency Braking) is an automatic emergency braking system that, by 2026, must detect cars, pedestrians, and cyclists.
• FCW (Forward Collision Warning) alerts the driver of a frontal collision before the braking system activates.
• Junction Assist is a new feature becoming standard in cars priced in the low millions (THB) that helps brake while turning through intersections.

2. Highway Assist Systems

• ACC with Stop & Go (Adaptive Cruise Control) adjusts speed based on the vehicle ahead, bringing the car to a stop and restarting automatically.
• LKA / LTA (Lane Keeping / Tracing Assist) helps keep the vehicle centered in the lane, not just warning when drifting out.
• TJA (Traffic Jam Assist) provides automated driving support during heavy traffic congestion.

3. All-around Awareness Systems

• BSD (Blind Spot Detection) warns of blind spots visible in the side mirrors.
• RCTA (Rear Cross Traffic Alert) alerts the driver to vehicles crossing behind when reversing, especially important for large vehicles.
• 360° Surround View Monitor is a 3D camera system offering a bird’s-eye view of the surroundings.

New Trend in 2026 Driver Monitoring System (DMS) uses facial recognition cameras to warn when the driver is drowsy or distracted, a new requirement under international safety standards in 2026.
