ABSTRACT:
In a vehicular drive assist system for warning a driver to pay attention to a preceding vehicle running ahead when a vehicle comes close to the preceding vehicle and the distance between these two vehicles becomes smaller than a safe inter-vehicle distance, this safe inter-vehicle distance is automatically established in two stages according to traffic conditions. One stage is where road is empty and another is where road is crowded. Since the safe inter-vehicle distance at the crowded condition is established to be a smaller value than the one at the empty condition, when road is crowded, due to the shortened safe inter-vehicle distance, warning is prevented from being issued so frequently.
