Abstract: Disclosed are a drive-by-wire chassis cyber-physical system under an intelligent traffic environment and a control method. The system includes: an SoS-level CPS, a system-level CPS, and a unit-level CPS, data transmission is realized between a plurality of unit-level CPSs and one system-level CPS, and data transmission is realized between a plurality of system-level CPSs and one SoS-level CPS. The system integrates a hub motor with a suspension, cancels traditional structures such as an engine and a clutch, and simplifies the structure of a chassis. A motor directly drives a vehicle to run, and different driving, braking or torque is applied to different wheels through four hub motors, so as to meet independent control of the wheels and improve active safety and operational stability.
