Smart Door Anti-Collision Sensors and Automotive Intelligent Door Protection

Introduces the intelligent automatic door anti-collision system based on TF-NOVA LiDAR, which effectively avoids collisions and reduces economic losses through real-time environmental perception and rapid obstacle avoidance measures.

Intelligent automatic doors can perceive the surrounding environment in real time, including pedestrians, other vehicles, and static obstacles. When potential collision risks are detected, the system can quickly take obstacle avoidance measures, such as automatically stopping the door opening action or adjusting the opening speed and angle of the door. This effectively prevents collision accidents and reduces economic losses caused by door bumps and damage.

To better understand the environment around the car door and achieve automatic obstacle avoidance, Benewake focuses on researching how to better solve corner cases for electric door obstacle avoidance. The goal is to make the sensor a better "eye" for the car door, capable of real-time monitoring and intelligent identification of the surrounding environment, predicting potential risks in advance, and avoiding them.

The TF-NOVA line-spot LiDAR is compact and easy to install discreetly without compromising the aesthetic appeal of the vehicle body. The compact TF-NOVA can be hidden under the side mirror, with the LiDAR's detection range parallel to the car door and tilted outward by approximately 20 cm. In this way, the protection zone formed by the LiDAR moves with the car door and always detects a distance ahead on the door's opening trajectory.

In the protection zone greater than 20 cm, the system ensures no obstacles are missed, even when facing vehicles with black or high-gloss paint. With a detection frequency of up to 500 Hz, the TF-NOVA demonstrates faster response speeds whether encountering metal obstacles, pedestrians, bicycles, or other fast-moving objects near the door. It triggers system alarms in time, effectively enhancing driving safety.

Technical Features

• Easy installation with strong adaptability to various car models, maintaining the aesthetics and integrity of the vehicle body
• Stable detection of black and high-gloss vehicles, with a 14°*1° field of view, forming a protection zone >20 cm
• Uses 500 Hz high-frequency laser detection to timely detect fast-moving objects without missing inspections
