car blind spot detection system

Why install a blind spot monitoring system?

Why install a blind spot monitoring system

Because there is no car designed to completely exclude the blind spot. As there is a visual blind spot in the rear view mirror of the car, you can’t see the vehicles in the blind spot before changing lanes, and if there are overtaking vehicles in the blind spot, changing lanes at this time will lead to a collision. In heavy rain, foggy weather, dim light at night, it is more difficult to see the vehicle behind, when changing lanes face greater danger, but we can take the next best thing and give you another “pair of wise eyes”, for you to pay attention to change lanes when the vehicle may not be found.

Car Blind spot Monitoring System 77GHZ H3

77G H3 bsd BLIND SPOT MONITORing system

– This pair of “wise eyes” is a 77GHz microwave radar, by installing two 77GHz radar sensors on the rear bumper of the car, the blind spot monitoring system will automatically start when the vehicle starts, in the vehicle driving speed is greater than 10KM/H start monitoring, real-time to the left and right sides of the body 3 meters The system analyzes and processes the reflected microwave signal, which can know the distance, speed and direction of movement of the vehicle behind, through the system algorithm, excluding fixed objects and away from the object, while not affected by the weather of rain, snow and fog, in the case of strong light, all black can work normally, when the detection of vehicles in the blind spot close, the indicator light flashes, at this time The driver can not see the vehicle in the blind spot, but can also know through the indicator that there is a vehicle coming from behind, changing lanes with the risk of collision, if the driver still does not notice the indicator flashing, turn signal, ready to change lanes, then the system will issue a bi bi bi voice alarm sound, again remind the driver of the danger of changing lanes, should not change lanes. Through the entire driving process, uninterrupted detection and reminder, to prevent the driving process due to bad weather, driver negligence, blind spots in the rearview mirror, newcomers to the road, and other potential dangers caused by traffic safety accidents.

The reason why this blind spot monitoring system is a good thing is that it can reduce the possibility of collisions when we change lanes while driving. The reason why changing lanes is prone to collisions is because of the existence of blind spots in the rearview mirror. Other cars are located in the blind spot, we can not see, then rashly changing lanes is likely to occur in traffic accidents. When changing lanes, when driving in the rain and fog when the rearview mirror blurred, night driving by the back of the high beam shaking eyes, will be used. When changing lanes mainly to avoid collisions due to blind spots with cars, rain and fog days and night driving by shaking mainly because of the rearview mirror effect is not good, more need, blind spot monitoring system to provide an auxiliary role to prevent the occurrence of danger, which greatly improves our driving safety.

Blind spot monitoring system, advance warning, driving assistance, so that the danger away from you.


As the current stage of car design can not completely exclude the visual blind spot but can be configured with advanced auxiliary equipment to solve this problem. With the increase of car ownership, how to reduce the incidence of traffic accidents and accident mortality has become an urgent problem, one of the most effective ways to solve this problem is to configure advanced driving assistance systems to improve the safety of car driving and minimize the incidence of accidents and accident mortality. Blind spot monitoring system, also known as merge assist system, or BSM or BLIS for short, is a safety class of high-tech configuration on the car, the main function is to sweep away the blind spot in the rearview mirror, through the microwave radar detection of the vehicle on both sides of the blind spot in the rearview mirror overtaking vehicles, to the driver to remind, so as to avoid accidents in the process of changing lanes due to the blind spot in the rearview mirror, which also determines why we will gladly accept The blind spot monitoring system is a necessary help.

As many car owners know, many accidents in-car driving happen in merging, this is because the vehicle has a relatively large blind spot, can not fully observe the situation of the vehicle behind through the rearview mirror, so in the merging collision. The blind spot monitoring (lane assist) is a safety device that helps us check whether there are vehicles and pedestrians behind us when we are merging and helps us merge safely to improve our safety driving. Through the technology to solve the visual blind spot in the rearview mirror, to merge safety greatly provides.

For example, after the vehicle is equipped with a set of 77GHz blind spot monitoring system, the system’s radar sensor once confirmed that there are vehicles or other obstacles hiding in the driver’s blind spot range, it immediately sends instructions to the receiving device installed on the edge of the rearview mirror, and the lighted cursor on the mirror light or the interior cue light to warn the driver to pay attention to the existing vehicles in the blind spot, thus reducing the casual lane change caused by This reduces the safety risks caused by random lane changes. If the driver then turns on the turn signal and prepares to change lanes or turn, the driver is warned. For example, there will be a small flashing light in the rearview mirror or in the interior lights to warn the driver, as well as an audible warning. If the driver does not turn on the turn signal, then the warning light will remain on after monitoring the blind spot vehicle, but not flashing, when the vehicle behind is away or overtaking the warning light is extinguished, then you can safely change lanes. The blind spot monitoring system also has AOA active overtaking warning, when overtaking the vehicle in front of the warning lights on until the two vehicles to maintain a sufficient safety distance before going off, to prevent accidents, which greatly improves our driving safety.

In addition, the radar operates at 77 to 79 GHz and can detect oncoming vehicles at a significant distance of 50 meters. The operating temperature range of the blind spot monitoring system is -25 C to +75 C. In addition, this car blind spot monitoring system has the quality of being energy efficient. It has a power consumption of <3 W. In terms of monitoring, the horizontal angle range is 150. it also has a waterproof rating of IP67.
