Following distance control apparatus
First Claim
1. A following distance control apparatus for controlling a following distance, which is a distance between an own-vehicle and a front-vehicle running ahead of the own-vehicle, by controlling a movement of the own-vehicle, the following distance control apparatus comprising:
- a sensor provided in the own-vehicle so as to detect the front-vehicle;
a deceleration apparatus that decelerates the own-vehicle; and
a controller that controls said deceleration apparatus based on an output signal of said sensor, wherein said controller controls said deceleration apparatus according to selected one of a short distance control mode and a long distance control mode, the short distance control mode for controlling an actual value of the following distance to be shorter, the long distance control mode for controlling the actual value of the following distance to be longer; and
said controller also controls said deceleration apparatus so that, when said long distance control mode is selected, an overshoot is permitted more than when said short distance control mode is selected, the overshoot being a phenomenon in which the own-vehicle moves excessively toward a near side of the front-vehicle.

Abstract
A follow distance control apparatus controls a follow distance without giving an uncomfortable feel to a driver during a deceleration control regardless of a selected control mode. A front-vehicle running ahead of an own-vehicle is detected by a sensor such as a radar. A deceleration apparatus, which decelerates the own-vehicle, is controlled by a controller based on an output signal of the sensor. The controller controls the deceleration apparatus according to selected one of a short distance control mode and a long distance control mode. In the short distance control mode, an actual value of the following distance is controlled to be shorter. In the long distance control mode, the actual value of the following distance is controlled to be longer. The controller also controls the deceleration apparatus so that, when the long distance control mode is selected, an overshoot that is a phenomenon in which the own-vehicle moves excessively toward a near side of the front-vehicle is permitted more than when the short distance control mode is selected.
