PURPOSE: A steering wheel suspension system of a vehicle is provided to make change of wheel geometry achieved in an optimum condition actively by hydraulic pressure through electronic control according to the running conditions of a vehicle. CONSTITUTION: A steering wheel suspension system of a vehicle comprises a wheel support(2) of supporting a wheel to turn the wheel; an upper control arm(3) and a lower control arm(4) of connecting the upper and lower sides of the wheel support with a vehicle body; a camber control unit(5) of controlling a camber, with pushing or pulling the upper and lower control arm; a caster control unit(6) capable of controlling the caster angle by moving the lower control arm back and forth; a toe control unit(7) capable of controlling the toe condition of the wheel support; and an ECU(Electronic Control Unit) of controlling the control units by signals input from a speed sensor, a steering angle sensor, and a lateral force sensor. Riding comfort and stability are secured by achieving the wheel geometry with the optimum condition.
