LiDAR device having a smart power management system and an operating method of the lidar device implementing the smart power management system

A vehicle comprising:

• a vehicle body;
• a light detection and ranging (LiDAR) device configured to operate in a first operation mode and a second operation mode in which a power consumption per unit time is lower than a power consumption per unit time of the first operation mode;
• and
• a controller;
• wherein the controller is configured to:
• transmit a first trigger signal to the LiDAR device when a state of the vehicle is changed from a first state to a second state;
• and
• transmit a second trigger signal to the LiDAR device when the state of the vehicle is changed from the second state to the first state;
• wherein the LiDAR device is configured to:
• change an operation mode of the LiDAR device from the first operation mode to the second operation mode when the LiDAR device receives the first trigger signal;
• and
• change the operation mode of the LiDAR device from the second operation mode to the first operation mode when the LiDAR device receives the second trigger signal.
