It is easy to install and operate and can be mounted on various types of vehicles, including construction, transport, special, and private passenger vehicles. This device can achieve a long detection range of up to 180 meters, with millisecond-level response speed. The main control board collects and analyzes the data from the laser radar and triggers an alarm when the distance between the vehicle and the obstacle ahead falls below the set threshold. The compact size of the sensor allows for integration through embedded installation in the vehicle’s radiator grille or near the license plate. Installing a laser radar sensor in the front of a vehicle is an effective solution. Technical Application of Long-Range Laser Radar Sensors Among these methods, laser ranging is recommended by industry experts for measuring safe distances between vehicles. There are two specific methods for laser ranging: continuous wave and pulsed wave. Laser ranging operates similarly to microwave radar ranging. Microwave ranging uses the reflection of electromagnetic waves from the target to locate and determine its position. An ultrasonic generator continuously emits ultrasonic waves at a frequency of 4 kHz, which are reflected and transformed into reflected waves when encountering obstacles.Īfter receiving the reflected wave signal, the ultrasonic receiver converts it into an electrical signal, allowing the measurement of the distance to the target. Ultrasonic ranging is based on the reflection characteristics of ultrasound. If the distance between vehicles falls below the safe threshold, an automatic warning should be triggered, and braking measures should be taken to prevent collision accidents and ensure the safety of the driver.Ĭurrently, there are three main methods for measuring safe distances between vehicles: ultrasonic ranging, microwave radar ranging, and laser ranging. The primary challenge in collision avoidance technology is maintaining a safe distance between vehicles. Vehicle collision warning systems are generally used to assist drivers in preventing major accidents such as high-speed and low-speed rear-end collisions, unintentional lane departures at high speeds, and collisions with pedestrians. The development of these systems is driven by the promotion of road traffic safety regulations and the iterative upgrades of active safety devices in vehicles. As the importance of reducing accidents and casualties in car travel grows, vehicle collision avoidance systems have become increasingly crucial and urgent. With the increasing number of vehicles on the road, rear-end collisions account for 30%-40% of traffic accidents.
