Vehicle follow-up control apparatus
First Claim
1. A preceding vehicle follow-up control apparatus for a vehicle comprising:
- vehicle speed detecting means for detecting a vehicle speed of the controlled vehicle;
vehicle-to-vehicle distance detecting means for detecting a vehicle-to-vehicle distance between the controlled vehicle and a preceding vehicle cruising ahead of the controlled vehicle;
relative speed calculating means for obtaining a relative speed between the controlled vehicle and the preceding vehicle;
target speed calculating means for calculating a target vehicle speed which is employed to adjust the vehicle-to-vehicle distance at a target vehicle-to-vehicle distance, said target speed calculating means calculating the target vehicle speed by employing a form which includes a linear connection between a product of a first gain and a difference between the vehicle-to-vehicle distance and the target vehicle-to-vehicle distance and a product of a second gain and the relative speed; and
vehicle speed control means for controlling driving power of the controlled vehicle to adjust the detected vehicle speed to the target vehicle speed.

Abstract
A preceding-vehicle follow-up control apparatus is arranged to calculate a target vehicle speed for following-up a preceding vehicle at a target vehicle-to-vehicle distance. The target vehicle speed is calculated from an equation having a form of a linear combination of a form which includes a linear connection between a product of a first gain and a difference between the vehicle-to-vehicle distance and the target vehicle-to-vehicle distance and a product of a second gain and the relative speed. The control apparatus controls a driving apparatus and a transmission apparatus of a vehicle so as to adjust a vehicle speed at the target vehicle speed. This enables the vehicle-to-vehicle distance to be converged into a target value without excessively increasing or decreasing the relative speed during this follow-up control.
