Abstract

The system comprises: detector devices (1) operable to provide electrical signals indicative of the relative distance and relative speed of the motor vehicle (V) with respect to a fixed or moving obstacle (O) ahead, and a processing and control unit (ECU) connected to such detector devices (1) as well as to brake actuators (2-4) and arranged to cause activation of the brake actuators (2-4) to effect automatic emergency braking of the motor vehicle (V) when the relative distance between the motor vehicle (V) and an obstacle (O) ahead lies between a first predetermined limit value (dF) equal to the minimum value at which it is still possible to avoid collision by braking and a preselected intermediate value (dE) comprised between said first limit value (dF) and a second limit value (dEcrit) which is less than the said first limit value (df) and is equal to the minimum relative distance value at which it is still possible to follow a path which avoids the obstacle (O), or when the relative distance (dR) becomes less than said second limit value (dEcrit).
