Core Viewpoint - The automotive smart corner module is a next-generation technology that integrates driving, braking, steering, and suspension systems into each wheel of the vehicle, enabling a fundamentally different driving experience. This technology is crucial for the intelligent upgrade of new energy vehicles and is expected to drive the automotive industry towards a new ecosystem characterized by "hardware modularization + software definition" as costs decrease and standardization accelerates [2]. Market Size and Trends - The global market size for automotive smart corner modules is projected to reach $49.63 million in 2024, with a compound annual growth rate (CAGR) of 17.16% from 2020 to 2025. By 2031, the market is expected to grow to $101.50 million, with a CAGR of 8.35% from 2025 to 2031 [4]. Industry Development Characteristics - The integration of electric motors, reducers, brake actuators, and sensors in smart corner modules allows for intelligent collaborative control of torque, braking force, and steering angle, providing a core execution basis for electric chassis and intelligent driving [8]. - High technical barriers exist in manufacturing and supply chain, requiring high-precision electromechanical coupling and complex thermal management, with leading companies primarily being Tier 1 manufacturers with chassis and intelligent control system expertise [8]. - Costs are decreasing while reliability is improving due to advancements in semiconductor integration, motor miniaturization, and electronic braking, creating conditions for large-scale production [8]. Favorable Factors for Industry Development - The global demand for new energy vehicles is steadily increasing, with a rising penetration rate and a shift towards electric and drive-by-wire systems, making smart corner modules essential components of intelligent electric chassis [10]. - The development of autonomous driving and intelligent chassis technologies is closely linked, with smart corner modules being key execution units for independent control of vehicle posture, torque distribution, braking, and steering, thus expanding their application space as the penetration of L3 and above autonomous driving increases [10]. - Government policies are increasingly supportive, promoting the development of key technologies for intelligent connected vehicles and modular electric drive systems, providing a favorable regulatory environment for the industrialization of smart corner modules [11]. Unfavorable Factors for Industry Development - The long verification cycle for safety and reliability of smart corner modules, which must meet ASIL-D standards, poses challenges for mass production due to strict testing requirements [13]. - The lack of unified industry standards and interface specifications among manufacturers hinders interoperability and collaboration within the supply chain, affecting large-scale manufacturing [13]. - Market acceptance of modular chassis architectures is still developing, with some manufacturers cautious about the long-term reliability and maintenance of smart corner modules, slowing the market adoption pace [13].
