Abstract
A system for controlling running safety of a vehicle having an alarm and an automatic braking system. A plurality of decelerations .alpha.2n of an obstacle such as another vehicle present ahead on the road is predicted and corresponding manipulated variables .alpha.1n (braking amount) to be supplied to the vehicle which indicate possible deceleration of the vehicle are determined. Then threshold values L.alpha.2n for alarming and automatic braking are determined corresponding to the predicted deceleration and are successively compared with the distance to the obstacle. When the distance falls below any of the threshold values, alarming or automatic braking is effected to avoid contact with the obstacle, thereby making the system relatively simple and enabling operation to match the driver's expectations.
