When a vehicle runs along a curved path, successive values of a speed limit are calculated based on the yaw rate of the vehicle, and values of acceleration demand are calculated and applied to control the actual vehicle speed based on the speed limit. If commencement of oscillation of the yaw rate and acceleration demand is detected, due to running along the curved path, guard processing is applied to the values of speed limit used to calculate the acceleration demand or is applied to the acceleration demand, such as to prevent the acceleration demand from varying in a direction that would increase the speed limit. Instability of deceleration control due to the oscillation is thereby substantially suppressed.
