PROBLEM TO BE SOLVED: To provide a control for enhancement of vehicle stability not being influenced by the sensor error or a drift. SOLUTION: A control system 56 according to the invention for enhancement of the vehicle stability includes a side-slip acceleration estimation module 62 configured as containing a side-slip acceleration estimation module 78 to decide the estimated side-slip acceleration. A frequency limiting integrator 80 decides the presumptive side-slip velocity through integration of the estimated side-slip acceleration. A reset logic module 82 erases the output of the integrator 80 when the first condition is generated. The first condition is one of the straight running condition, the velocity condition, and the sensor error condition. The estimated side-slip velocity prepares a side-slip control signal by making comparison with the desired sideways sliding velocity. The side-slip control signal is coupled with the yaw rate control signal to prepare a working device control signal. At least one of the brake applying devices or a rear wheel steering actuation device receives the working device control signal and prepares the yaw moment for correcting the dynamic behavior of the vehicle.
