All motorists inevitably have visual blind spots and try to avoid driving in the visual blind spots of other drivers. Likewise, inadequate observation of your own blind spot can increase the potential danger. If you find your car in the other driver’s blind spot, you should accelerate or decelerate in time to leave the other driver’s visual blind spot as soon as possible.
Visual blind spots of small vehicles
All vehicles have a visual blind spot in the right rear corner. If the front bumper of the vehicle in the next lane is flush with your rear bumper or crosses your rear bumper, the vehicle will not be visible from your rearview mirror at that time. Before changing lanes, in addition to looking in your mirrors at the vehicle next to you, check your side blind spots, as other cars, motorcycles or bicycles may be “hiding” in your blind spot.
Visual blind spots of large vehicles
Unlike small cars, large vehicles are invisible to drivers directly behind them, and they also have larger blind spots on both sides, such as heavy trucks and buses, which are shown in yellow. If you drive in such a blind spot, the driver of the large car can not see your car, that is, your car in the large car driver’s field of view “disappeared”, so the risk of collision in these areas is very high. So you should try to avoid driving in the blind spots of large vehicles and be very careful when passing through them.
Blind spots on both sides
Large blind spots exist on both sides of large vehicles. When you cannot see the face of the driver of the large vehicle in the outside mirror, he will not be able to see you either. If the driver of the large vehicle changes lanes at this point, there is a risk of a collision.
Blind spot in front of the car
Don’t jump in front of a large car soon after overtaking. Large vehicles need twice as much time and space to stop as small cars. When returning to your original lane to pull in front of a large vehicle, make sure you can see the entire front of the large vehicle in your rearview mirror and do not slow down.
Blind spot behind the car
Unlike small cars, large vehicles have a huge blind spot directly behind them. When the driver of a large car cannot see your car behind them, you will not see the front of the large car either. If the driver of the large vehicle brakes suddenly, you could be rear-ended. So always keep a safe following distance.
The blind spot in the car driving process of life and death
Driving safety is a matter of great importance, back-up radar and backup video have become standard today, why are accidents still frequent? The neglected visual blind spot is an important reason. Among them, the side wheel difference blind zone, side and rear overtaking lane change blind zone and rear side vehicle approaching blind zone these blind zones are the easiest to be ignored by the driver but are the most likely to occur serious accidents blind zone.
For the vehicle driving blind spot, automotive safety equipment manufacturers have introduced solutions based on millimeter wave radar technology development.
- Blind spot detection system
This system detects the side of the body through a 2-millimeter wave radar. Solve the body side reflector and rearview mirror blind spot. But this system can not detect the rear approaching vehicles.
2, vehicle proximity detection system
The vehicle approach detection system for the rear of the vehicle. The rear of the vehicle is safely monitored by a 2-millimeter wave radar behind the body.
LCA (lane change assist) lane change assist system, uses the superior performance of millimeter wave radar in detection distance, accuracy, detection angle, anti-interference, response speed, etc., using a 24Ghz millimeter wave radar sensor while detecting the rear of the body and side visual blind spot. Include the blind spot detection system to detect the side blind areas at the same time also take into account the vehicle proximity detection system to detect the rear of the vehicle. Also due to the superior performance of millimeter wave radar, there are outstanding improvements in detection accuracy and anti-interference, and response speed. With a long detection distance (20 meters), strong ability to penetrate fog, smoke and dust, all-weather (except heavy rain) all-day feature; fast response, ability to monitor the speed of moving objects to distinguish the difference between lane railings, tunnel walls, and vehicles that are about to overtake from the side. Can actively monitor vehicles overtaking from the left and right rear while driving, and actively prompt the driver if there is any oncoming traffic from the side rear.
How it works: When the car speed exceeds 10KM/H, the lane change assist system starts automatically and monitors the oncoming traffic from the rear in real-time. When an oncoming car is monitored at the side and rear, the LED light will come on; if the turn signal is activated at this time and the lane change is made to the side with a car, the buzzer will sound an alarm to warn the driver and avoid a collision at the side.
Precisely measured data information
Through the millimeter wave radar’s continuous scanning of the visual blind area, the distance, angle, speed, and other information of the objects in the area are obtained. Combined with software algorithms for optimization and analysis, it pinpoints vehicles that pose a potential danger to the owner, allowing for more accurate warning information to be provided.
All-weather real-time data update
Combined with millimeter-wave radar in high penetration, all-weather, good environmental performance characteristics, in fog, rainstorm, and other adverse weather conditions, but still, give owners more powerful safety protection. The side of the vehicle in advance to make a distance warning.
Because of its many superiorities, millimeter wave has been widely used in military and civilian fields.
