Abstract This article explores the roles of DCU, MCU, and MPU in the electronic and electrical architecture of autonomous driving, comparing the advantages of distributed and centralized architectures, as well as the development history of ADAS systems from L0 to L2+. It focuses on the differences between MCU and MPU, and their key roles in … Read more
Overview The surround view system utilizes four wide-angle fisheye cameras around the vehicle, typically installed at the front, rear, and below the side mirrors, to create a 360-degree blind spot-free coverage around the vehicle. The surround view system provides a panoramic parking video assistance and integrates multiple warning functions, becoming an important component in the … Read more
In-Vehicle Cameras: The Eyes of Autonomous Driving In-vehicle cameras are known as the “eyes of autonomous driving” and are the core sensing devices in ADAS systems and the field of automotive autonomous driving. They mainly collect image information through lenses and image sensors, achieving 360° visual perception and compensating for radar’s shortcomings in object recognition, … Read more
Author / A Bao Editor / A Bao Produced by / A Bao 1990 As mentioned earlier, with each increase in the level of autonomous driving, the required computing power of the chips will increase by dozens of times. The computing power requirement for L2 level autonomous driving is only 2-2.5 TOPS, but for L3 … Read more
1. ADAS/AD System Solutions (1) L0-L2 Level ADAS Solutions As mentioned earlier, most early L0-L2 level ADAS systems are based on a distributed controller architecture. The entire ADAS system consists of 4-5 ADAS subsystems, each of which is usually an all-in-one solution (which can be viewed as a smart sensor). Each subsystem exclusively occupies the … Read more
Among the various application scenarios for storage devices, the automotive sector is recognized as the next blue ocean market with high growth potential. However, in the past decade, global automobile sales have stabilized at around 80 to 90 million units per year. Therefore, the industry is not only focused on the incremental market brought about … Read more
Introduction: This article is authorized for publication by Zhiche Technology, written by Old Hong. Recently, the State Administration for Market Regulation of China and four other departments held discussions with Tesla. Not to mention autonomous driving, there are even basic safety issues—battery fires, unintended acceleration, and vehicle remote upgrades (OTA), among others. As for automotive … Read more
