A system is provided for calculating variable forward and backward unsafe distances between two tailgating vehicles for generating variable forward and backward staged Time-to-Collision pulses in real-time driving. The system also generates low-speed pulses and uses its speed sampling method for producing forward and backward distance reduction rate pulses.The system uses the staged backward Time-to-Collision pulses and the backward distance reduction rate pulses for producing distance warning signals on the rear of its host vehicle. The system also uses its low-speed pulses for implementing a stoplight on the rear of vehicles regardless of vehicles’ distance. The system provides the staged forward Time-to-Collision pulses and the forward distance reduction rate pulses for supporting Autonomous Emergency Braking (AEB) system of its host vehicle with braking and steering initiation and intensity.
