The global automotive industry is always a fast growing and highly competitive field as every participant involved
relentlessly thrives to achieve technological advancement of their product and solution to stand-out among the rest. Lately, the
pursuit towards developing a fully autonomous car has intensified manifold among all the automakers because of the increasing
need for advanced driving assistance and safety. In the era of AI advancements, self-driving cars is so much more challenging
that most people expected. Autonomous vehicle requires L3 or higher level smart connected capability to function efficiently and
LiDAR is at the forefront in serving the requirement. This paper is set to explicitly furnish all the technical and functional
development of a number of LiDAR technologies in existence in the automotive ecosystem and also systemically distinguish and
analyze each of them. In addition, this paper provides recent advancement and development of key automotive LiDAR
technology, startups, trends.
