In recent years, with the rapid advancement of intelligent driving technologies, ADAS (Advanced Driver Assistance Systems) has become a vital component of modern vehicles. As the core enabler of ADAS functionality, automotive electronic chips play a critical role in enhancing driving safety and comfort. This article provides an overview of the fundamental knowledge, key technologies, and development trends related to ADAS chips.
What Is ADAS?
ADAS (Advanced Driver Assistance Systems) refers to a set of systems that assist drivers by integrating various sensors and control units. Key functions include lane keeping, automatic emergency braking, adaptive cruise control, and blind spot monitoring, all designed to enhance driving safety and reduce traffic accidents. Currently, ADAS technologies are primarily implemented in Level 2 and Level 2+ autonomous driving systems, and are expected to evolve towards higher levels of autonomy in the future.
Key Types of Chips in ADAS Systems
The implementation of ADAS systems relies on various types of chips, mainly including the following categories:
