Abstract
A method for preventing a subject vehicle from driving into a vehicle ahead includes equipping the subject vehicle with at least one brake system, a drive system and a driver assistance system with an emergency braking function. The method also includes issuing a haptic warning when the subject vehicle enters a distance warning zone, applying emergency braking on entering an emergency braking zone, and calculating a relative speed between the subject vehicle and the vehicle ahead. The method includes continuously calculating a time to collision (TTC) when approaching the vehicle ahead, specifying a first TTC threshold value for adaptive classification of a distance from the subject vehicle to the vehicle ahead, checking, when approaching the vehicle ahead, whether the TTC falls below the first TTC threshold value, and, if the TTC falls below the first TTC threshold value, issuing a haptic warning to a driver of the vehicle.
