ABSTRACT:
In a drive assist system of a vehicle having a function of detecting an inter-vehicle distance between vehicles and a warning is given to a driver for preventing a collision, disclosed are an apparatus for detecting a deceleration of a preceding vehicle based on a vehicle speed of the preceding vehicle, an apparatus for establishing a safe inter-vehicle distance between the vehicle and the preceding vehicle based on the deceleration of the preceding vehicle, and an apparatus for comparing the inter-vehicle distance with the safe inter-vehicle distance and for outputting a warning signal when the inter-vehicle distance is smaller than the safe inter-vehicle distance. Thus, when the deceleration of the preceding vehicle is small, the warning is not issued until the inter-vehicle distance becomes small, whereby the driver's intention can be reflected on the drive assist system.
