Foreword
In August this year, I began to answer questions about autonomous driving on Zhihu. So far, I have answered nine related questions and my answers have been recognized by many members, among which six have been recommended by editors.
Some of my fans send me messages asking for a column where I can share more useful information. In order to run this column well, I will irregularly update the “Introduction to Autonomous Driving Technology” with my shares.
I will explain the hardware principles of autonomous driving from the perspective of a beginner, in the most popular language.
After the hardware explanation is completed, I will help readers to understand how autonomous driving technology is implemented through code by combining the Apollo open source code released by Baidu.
Main content
Let’s get back to the topic.
What I am going to share recently is the “Introduction to Autonomous Driving Technology (Hardware Section)”.
I will explain the principles, performance boundaries, data formats, and functions of a certain type of sensor in autonomous driving vehicles in each share.
These sensors include:
- GPS+IMU Global Positioning + Inertial Measurement
- Camera Visual Sensor
- Lidar Laser Sensor
- Millimeter Wave Radar Millimeter Wave Radar
- Ultrasonic Radar Ultrasonic Radar
- Vehicle Control Unit Signals VCU Signal
- Autonomous Vehicle Controller Autonomous Driving Controller
