Abstract

A system for controlling running safety of a vehicle having an alarm and an automatic braking system. A plurality of decelerations α2n of an obstacle such as another vehicle present ahead on the road is predicted and corresponding manipulated variables α1n (braking amount) to be supplied to the vehicle which indicate possible deceleration of the vehicle are determined. Then threshold values Lα2n for alarming and automatic braking are determined corresponding to the predicted deceleration and are successively compared with the distance to the obstacle. When the distance falls below any of the threshold values, alarming or automatic braking is effected to avoid contact with the obstacle, thereby making the system relatively simple and enabling operation to match the driver's expectations.

Dependent claims

A system for controlling safety running of a vehicle, comprising:

obstacle detecting means for detecting an obstacle present ahead on a course of travel of the vehicle;
parameter detecting means for detecting parameters indicative of motion of the vehicle including at least speed of the vehicle;
relative condition detecting means for detecting condition of the obstacle, detected by the obstacle detecting means, relative to the vehicle;
deceleration predicting means for predicting a plurality of decelerations which the obstacle could generate, based on the parameters detected by the parameter detecting means and the relative condition detected by the relative condition detecting means;
operation determining means for determining whether at least one of alarming and contact avoidance with the obstacle should be operated based on at least the plurality of the predicted decelerations;
and
effecting means for effecting the operation determined by the operation determination means.
