Abstract:
A vehicular velocity controlling apparatus for an automotive vehicle, comprising:an inter-vehicle distance detector to detect an inter-vehicle distance from the vehicle to a preceding vehicle which is running ahead of the vehicle; an inter-vehicle distance calculating section that calculates a target vehicular velocity to make a detected value of the inter-vehicle distance substantially equal to a target inter-vehicle distance; a vehicular velocity detector to detect a vehicular velocity of the vehicle; and a vehicular velocity controlling section that adjustably controls the vehicular velocity of the vehicle to make a detected value of the vehicular velocity substantially equal to the target vehicular velocity, the vehicular velocity controlling section including a target braking pressure calculating section that calculates a target braking pressure for a vehicular brake system in accordance with a target deceleration variable calculated on the basis of the target vehicular velocity and the detected value of the vehicular velocity; and a target braking pressure limiter to place a limitation on a rate of increase in the target braking pressure when the target braking pressure is in excess of a predetermined braking pressure threshold value.
