The voice coil motor-assisted unmanned heavy duty truck is reliable. May Be related to video contact more often see a heavy truck driving, small will hide far away, afraid of a careless disaster from the sky! Although most heavy truck drivers choose experienced old drivers, there are many blind spots in their heads, so heavy truck accidents are common. 

     With the continuous development of automatic driving technology, heavy trucks are also moving with the Times. However, the small editor of Voice Coil Motor learned that on November 9, Saic Motor, Shanghai Port Group and China Mobile jointly announced The three parties will officially launch the 5G + L 4 class smart driving heavy truck demonstration operation on the line from Shanghai Deep Water Port Logistics Park via Donghai Bridge to Yangshan Wharf. 

     As far as the voice coil motor sub-series is aware, the above-mentioned lines cover such complicated scenes as ordinary roads, highways, wharves, stacking yards, heavy traffic at night, etc. One-sixth of the time each year also has to withstand the east China Sea Bridge 7 above the test of high winds. And the smart heavy truck launched by SAIC carries the vision perception, laser radar, millimeter wave radar, satellite and inertial navigation integrated system developed independently, and integrates advanced technologies such as AI (artificial intelligence) , 5g, V2X (vehicle communication) , etc. It can realize the L4 level automatic driving, centimeter level positioning, accurate parking, interaction with automatic port machinery and equipment, and the train running of Donghai Bridge under the fixed scene of port area. The focus of the project is that the smart heavy truck launched by SAIC applies to Lidar, which is one of the typical application fields of voice coil motors. Lidar transmits a laser beam and then receives the beam reflected from a distant object The distance information of distant object can be obtained by measuring the time of flight of the light beam. However, laser beams are very narrow and they do not scatter, so a single lidar pulse can only sense a very small object. For practical use, the Lidar Sensor has to be scanned in some form. Most Lidar sensors are connected to a drive motor that rotates them, and once the laser is synchronized with the motor's motion, we can tell where the laser is pointing and combine the whole image of the environment ahead. Therefore, the field of view (Fov) of Lidar depends on the angle of rotation of the motor.

      The Voice Coil Motors developed, manufactured and sold by Kunshan include cylinder Voice Coil Motor, flat voice coil motor, rectangular voice coil motor, swing voice coil motor and shaft voice coil motor.
