ABSTRACT:
A collision preventing apparatus of a vehicle for preventing a collision with a preceding vehicle running ahead of the vehicle has an image processor and a computer for calculating inter-vehicle distance, an inter-vehicle distance between the vehicle and the preceding vehicle, and a safe-inter vehicle distance between the vehicle and the preceding vehicle while observing a third vehicle running ahead of the preceding vehicle, judging a hazard of collision with the preceding vehicle based on the inter-vehicle distance and the safe inter-vehicle distance, and warning a driver of the hazard. Since the vehicle having the collision preventing apparatus runs calculating the inter-vehicle distance in conjunction with the third vehicle, a collision with the preceding vehicle can be prevented, even when a driver of the preceding vehicle applies an emergency brake to avoid a collision with the third vehicle running ahead of the preceding vehicle.
