The invention belongs to the technical field of automobile active anti-roll bars, and provides a stepless regulation FSAE racing car U-shaped electric control anti-roll bar system which comprises an anti-roll torsion bar, a transverse stable push rod, a rotary torsion arm structure and a rigidity control system, and the rotary torsion arm structure is used for connecting the anti-roll torsion bar and the transverse stable push rod; the number of the transverse stable push rods is two, and the transverse stable push rods are connected to the two sides of the anti-toppling torsion bar through the rotary torsion arm structures respectively. And the rigidity control system is used for realizing stepless adjustment of rigidity. According to the active anti-roll bar design for the FSAE racing car, through the mechanical structure design of the thin plate type torsion arm rotating mechanism and the control strategy design of the open-loop adjustment strategy, automatic stepless adjustment of the rigidity of the anti-roll bar of the FSAE formula racing car is achieved, and the steady-state steering characteristic of the car is improved.
