Does the Intelligent Speed Assistant (ISA) Enforce Compliance with Speed Limits?
No, Intelligent Speed Assistance (ISA) does not force you to comply with the speed limit. The system warns you as you approach the limit, and in some modes gently restricts acceleration; but the final word behind the wheel is always yours. You can al…

What Does a Lane Keeping System Mistake for a Lane During Road Works?
In roadworks, a lane tracking system's camera looks for painted lines; in situations like temporary yellow lines, old lines that weren't removed, cones, and unpainted fresh asphalt, no one can guarantee what the system will mistake for a lane. That's…

What Do Emergency Steering Intervention Systems Do?
Emergency Steering Assist is a safety system that, when braking alone is not enough to prevent a collision, touches the steering with small, quick interventions to steer the vehicle around the obstacle. In other words, while conventional automatic em…

Why Isn't Detecting Motorcycles as Easy as Half of the Emitter?
Car safety systems can now recognize pedestrians, cyclists and even deer; so why is a thin motorcycle still one of the hardest targets? Short answer: to cameras and radars, a motorcycle looks like merely a narrow, single-light, constantly moving obje…

How Do ADAS Systems See Pedestrians and Cyclists at Night?
At night, camera- and radar-based ADAS systems see pedestrians and cyclists far worse than in daylight; systems that prevent roughly 60% of collisions in darkness can raise this rate to 90% in daytime. In other words, the system's eyes genuinely weak…

Can Traffic Sign Recognition Systems Make Mistakes?
Yes, it can be wrong. Traffic sign recognition (TSR) systems, which use a camera to read speed limit and no-passing signs on the road, usually work correctly, but faded or covered signs, temporary signs in construction zones, different countries' sig…

How Are ADAS Systems Affected When Towing a Trailer or Caravan?
The moment you attach a trailer or caravan, your vehicle's ADAS systems lose their effectiveness: adaptive cruise control recalculates the following distance based on the trailer, blind spot monitoring watches behind the vehicle but not behind the tr…

How Does Adaptive Cruise Control Know to Slow Down Before Entering a Curve?
Adaptive cruise control knows to slow down before entering curves, because some systems use road curvature data from the vehicle's navigation map along with the front camera and traffic sign recognition. A system that reads the curve ahead before the…

Is It Right to Turn Off ADAS Systems, and When Should They Be Turned Off?
Disabling ADAS systems is often an unnecessary move; however, temporary shutdown can make sense in situations like snow-covered lane markings, sensors getting confused while towing a trailer, or automatic braking that brakes in the wrong place. Perma…

What Does Lane Keeping Assist Do When It Loses the Lane Marking?
When the lane keeping assistant loses the line, it first warns the driver, then cuts steering support and hands over full control to the driver; the absence of lines, snow, rain, or sharp curves can render the system useless. In other words, the mome…

Radar or Camera? The Difference in Sensor Technologies in ADAS Systems
In ADAS systems, radar measures distance and speed using radio waves, cameras process images to recognize lane markings, traffic signs, and pedestrians; ultrasonic sensors assist with parking at close range, while lidar uses lasers to create 3D maps …

Cars Say 'Level 2', What Exactly Does This Tell Us?
The 'Level 2' label means the car can manage steering and speed at the same time, but legal responsibility for everything it does still rests with the driver . In other words, the car is not, in theory, driving by itself; an assistant that is constan…
