Product Description
24GHz A-pillar Universal Version Blind Spot Monitoring System

I.Product Overview
BSM (Blind Spot Monitoring, Blind Spot Monitoring System) is an advanced automotive active safety technology. It is mainly used to detect obstacles (such as other vehicles, pedestrians or objects) in the blind spot on both sides and behind the vehicle, and alert the driver through visual or audible alarms to avoid collisions when changing lanes or steering. The system is widely used in high-end passenger cars, commercial vehicles and intelligent driving.
II.Working Principle
The system uses millimeter-wave radar sensors to monitor the environment behind and on both sides of the vehicle, monitor driving "visual field" blind spots, and provide an early warning function when the driver is driving normally or changing lanes.
III. Key Features
1,Blind Spot Monitoring
Turn on the car power and activate the blind spot monitoring function. The monitoring range is 4.4 meters horizontally on the side of the car and 10 meters behind the car. When a vehicle enters the monitored blind spot area, a warning prompt will be issued, and the warning will not be cancelled until the target object leaves the monitoring area.
(1)Level 1 warning: The yellow LED warning light is on.
(2)Level 2 warning: Turn on the turn signal, the buzzer beeps three times, and the red LED warning light flashes
2,Lane change warning (LCA)
During the driving process, the lane change warning function is continuously activated, The monitoring range is 4.4 meters horizontally on the side of the car and 10 meters behind the car. When the vehicle enters the monitoring blind spot, a warning prompt is issued until the target object leaves the monitoring area, and the warning is canceled. If the collision time with the vehicle behind the vehicle is less than 5 seconds within 50 meters, the system will issue a level one warning prompt.
(1)Level 1 warning: The yellow LED warning light is on.
(2)Level 2 warning: Turn on the turn signal, the buzzer beeps three times, and the red LED warning light flashes
3,Door opening warning (DOW)
After the car stops, activate the blind spot monitoring function. The distance behind the rear of the car is about 10 meters. When the vehicle enters the monitoring blind spot, a warning prompt will be issued until the target object leaves the monitoring area, and the warning will be canceled
(1)Level 1 warning: The yellow LED warning light is on.
(2)Level 2 warning: Turn on the turn signal, the buzzer beeps three times, and the red LED warning light flashes
4,Rear Cross Traffic Alert (RCTA)
When the reverse gear is engaged and a moving vehicle or pedestrian enters the monitoring area within 3-5 meters horizontally on the side of the car, a Level 1 warning is issued: the yellow LED warning light turns on. The warning will be canceled only after the target object leaves the monitoring area.
5,Active Overtaking Alert (AOA)
Monitors the surrounding environment in real time during overtaking, predicts potential collision risks, and warns the driver or automatically takes intervention measures to improve overtaking safety.
6,B-Pillar Blind Spot Vehicle Following at the Same Speed Warning
When it is detected that the vehicle in front of it and the vehicle traveling at the same speed have entered the blind zone of the B-pillar, and there is a potential collision hazard, the system will issue a timely warning signal to alert the driver, so that the driver can take appropriate measures to avoid the occurrence of a collision accident

Our Advantages
V. Product Advantages
1.Non-invasive installation
There is no need to break the wires. A special protocol box for the specific vehicle model is adopted.Just plug it into the original vehicle interface and it can be used immediately.It will not damage the original vehicle wiring and will not affect the vehicle's warranty!

2.Strong stability:Adverse Weather Adaptation
Excellent anti-interference, high-quality electronic components and advanced manufacturing processes are used, and extreme weather can also be warned with 0 delays
3. Extensive detection coverage compensates for visual blind zones, significantly enhancing driving safety.
4. Using millimeter microwave radar technology, the accuracy can reach ± 0.1 meters, ensuring the accurate monitoring of the target by the system
5. Adapt to a variety of road conditions: Whether it is the high-speed driving scene of the expressway, or the low-speed driving situation of frequent starts and stops on urban roads and complex intersections, the BSM system can work stably and continue to play a monitoring and early warning role.
6. Good compatibility: It can be widely adapted to various models, and some products also support personalized customization, providing exclusive driving safety solutions for each car owner.
