Abstract: A safety system for an automotive vehicle includes: a dedicated radio to receive and transmit state data between a host vehicle and a remote vehicle; a global positioning system (GPS) receiver; an on-board unit (OBE) to perform a vehicle-to-vehicle (V2V) communications so that the host vehicle receives state data of the remove vehicle in a basic safety message (BSM) format; and a safety control unit. In particular, the safety control unit receives the state data of the host and remote vehicles, calculates a separation distance, a prediction horizon time, and then compares the prediction horizon time with a driver reaction time to generate a warning to a driver. More specifically, the safety control unit performs a cost value procedure when a deducted prediction horizon time is greater than zero to determine variable coefficients for estimating a future position and speed of the host and remote vehicles.
