Abstract
In preview brake controlling apparatus and method for an automotive vehicle, a relative distance of the vehicle to an object for the vehicle to be braked is detected, a determination of whether the vehicle is approaching to the object on the basis of the relative distance of the vehicle to the object is made, a vehicular velocity variation rate (acceleration/deceleration) manipulation variable is made, the determination of whether the vehicle falls in a preliminary brake pressure application enabled state requiring a preliminary brake pressure application on the basis of results of detection at the steps of the approaching state detecting and of the vehicular velocity variation rate manipulation situation detection is made, and a predetermined constant brake pressure in accordance with a vehicular running condition prior to a vehicular driver's brake manipulation is developed when determining that the vehicle falls in the brake preliminary application enabled state.
