Laser ranging sensors for automotive collision avoidance detectors improve vehicle driving safety

With the continuous advancement of automobile technology and the development of autonomous driving technology, more and more distance detection equipment will continue to be launched. Most existing cars have collision prevention systems. The car collision warning uses laser ranging technology to identify the distance between the target car in front or behind the car in a non-contact manner. When the distance between the cars is less than the predetermined safe distance, the car collision avoidance system will brake the car urgently, or send an alarm to the driver, or make an instant judgment and response to the car's driving based on the target car's speed, distance, braking distance, response time, etc., which can greatly reduce traffic accidents.

In terms of autonomous driving, laser ranging technology can provide accurate environmental perception information for autonomous vehicles . By measuring the distance between the car and other objects, it can realize functions such as automatic obstacle avoidance and path planning, thus improving the car's autonomous driving capabilities.

Laser ranging has the advantages of short measurement time, large range and high accuracy. It can meet the ranging needs of cars from low speed to high speed, and avoid the ranging inaccuracy caused by slow ranging speed when the car is driving at high speed. Its advantages are more obvious when used on highways. In terms of driving collision avoidance, laser ranging driving anti-collision devices are usually combined with driving control systems to achieve automatic control and intelligent management. When the vehicle approaches an obstacle, the anti-collision device will sound an alarm or automatically brake to avoid collision accidents. In addition, laser ranging driving anti-collision devices can also be combined with other safety devices, such as infrared anti-collision devices, radar speedometers, etc., to form a driving safety protection system and improve driving safety performance.
