The invention discloses a drive-by-wire chassis domain control system which comprises a front wheel domain control system. The front wheel domain control system comprises a front wheel domain controller, two front wheel steering motors and two front wheel braking motors; the front domain controller comprises a first controller and a second controller which are the same in structure; the first controller comprises a first single-chip microcomputer, a front wheel braking force sensor, a front wheel speed sensor, a front wheel yaw angle sensor, a front wheel steering angle/displacement sensor, a front wheel power management chip, a front wheel steering motor pre-driving chip, a front wheel steering motor rotor position detection circuit and a front wheel braking motor pre-driving chip. The system comprises a front wheel brake motor rotor position detection circuit, a front wheel steering motor three-phase current measurement circuit, a front wheel brake motor three-phase current measurement circuit, a front wheel steering motor three-phase drive axle and a front wheel brake motor three-phase drive axle. The drive-by-wire chassis domain control system further comprises a rear wheel domain control system. According to the invention, braking and steering of the chassis are integrated on one system for centralized control.
