The application of ADAS and BSD on AI MDVR
ADAS contains many different technologies, such as: ACC adaptive cruise, AEB automatic emergency Braking, TSR/TSI traffic sign recognition, BSD/BLIS Blind spot detection, LCA/LCMA Lane change assistance, LDW Lane departure advance warning. Let's read it in detail.
LDW(Lane Departure Warning System) +( Lane Keeping LCA/LCMA)
The system consists of Cameras, sensors and controllers. The principle is to use a camera on the side of the car body or rearview mirror to sample the marking line of the current driving lane, and then obtain the current car position in the lane through image processing. The controller will send out a warning signal when the car veers out of the lane. From sensing to issuing a warning, the process only takes about 0.5 seconds to remind and wake up the driver in real time to avoid accidents.
PCW (Predictive Collision Warning) + EB (Emergency Braking)
Radar cameras and other sensors mounted on the car detect its own speed as well as the distance and speed of the vehicle in front of it. At the beginning, a warning sound will be sounded to remind drivers of their distance. If the driver does not respond and the distance continues to narrow, braking will be applied. The system will intervene to provide a braking effect to prevent collisions.
BSD / BLIS
A car driver's blind spot is an area that is invisible to the
left, right and inside of the rearview mirror. I'm sure many drivers are
impressed by blind spots. This is one of many accidents. Blind spot detection
systems use radar and sensors to detect blind spots behind the vehicle. When
the blind spot detects an approaching vehicle, it will warn the driver to help
minimize the possibility of an accident.
adaptive cruise system mainly uses the distance sensor installed in front of the
vehicle to continuously scan the road in front of the vehicle to understand the
speed and relative distance of the vehicle in front. It will automatically
detect the speed of the vehicle as it travels and adjust its speed accordingly
to maintain a safe distance from the vehicle in front of it to reduce the
likelihood of a collision.
Driver Fatigue Monitor System
Most current systems use cameras to examine drivers' faces to determine concentration and signs of sleepiness. Some systems use the frequency with which a driver's eyes open and close to identify levels of safety and provide appropriate warnings, or assist in action. If the driver's facial expression does not change much, or even if his eyes are closed, the vehicle will warn the owner through sound and lights to reduce accidents.
Night Vision Device, NVD
It can help the driver in the vision or bad weather night, automatically identify obstacles or large foreign objects, while warning the driver of the road ahead, to avoid accidents. The recognition method is to use infrared to sense the difference in heat, distinguish the difference between people, animals, vehicles and the environment, and convert it into images after processing, so as to clearly present the original unclear object in front of the driver, so as to reduce driving risks.
In addition to the above eight subsystems, ADAS System also includes: Global Navigation Satellite System, GNSS, RTTIReal Time Traffic Information, Car Networking System
