As one of the effective means for the electrification, intellectualization, and integration
of electric vehicle chassis, corner module technology is an important direction in the development
from centralized drive to distributed full-by-wire architecture. To comprehensively analyze the
development status and trends of this field, this paper summarizes the mainstream configurations
and key technologies of corner module technology, and draws the following conclusions. From the perspective of layout schemes, in-wheel motors and wheel-side motors each have their own
advantages in structural design, and complement each other in functional integration and unsprung
mass; moreover, double-wishbone, MacPherson strut, and trailing-arm suspensions also have their
respective advantages. From the perspective of technical routes, inner-rotor and outer-rotor inwheel motors exhibit different torque performance, thermal performance, and lifespan performance,
and current research mainly focuses on improving electromagnetic efficiency, enhancing thermal
performance, and reducing noise. From the perspective of control strategies, technologies based on
four-wheel independent steering have achieved favorable results by using model predictive control,
sliding mode control, fault-tolerant reconfiguration, and other methods, with significant
improvements in vehicle stability, trajectory tracking, and system safety. The review concludes that
although problems such as unsprung mass, thermal management, and cooperative control remain,
the combination of corner module technology with skateboard chassis and high-level autonomous
driving will further promote the development of electric vehicles in terms of intellectualization,
lightweight design, and safety.
