Efficient Power Control Using Variable Resolution Algorithm for LiDAR Sensor-based Autonomous Vehicle

초록

Light detection and ranging (LiDAR) sensors are used to detect the surrounding environment and the distance in autonomous vehicles. Conventional LiDAR sensors have the demerit of consuming constant power depending on the normal operation. In this paper, we propose an algorithm that improves the inefficient power consumption during the normal operation of a conventional LiDAR sensor. The LiDAR sensor with the applied algorithm provides efficient power saving by controlling resolution through a variable transmission period of a laser diode (LD) depending on the vehicle speed and the surrounding environment.
