Vehicle operation assist control system
First Claim
1. A vehicle operation assist control system for assisting a vehicle operator to operate a vehicle, comprising:
- map information means for providing map information of a road ahead of the vehicle;
vehicle operation assist means for assisting the vehicle operator to operate the vehicle; and
obstacle information acquiring means for acquiring information on an obstacle which lies ahead of the vehicle, said information including a distance to the obstacle and a width of the obstacle;
the vehicle operation assist means being adapted to determine an evasion path, when an obstacle is detected by the obstacle information acquiring mean, and modifying the map information provided by the map information means, according to the distance to the obstacle and the width of the obstacle detected by the obstacle information acquiring means.

Abstract
In a vehicle operation assist control system for assisting a vehicle operator to operate a vehicle, a distance to the obstacle and a width of the obstacle are detected by a radar or the like, and, when an obstacle is detected, the system determines an evasion path and accordingly modifies the map information available to the system. Therefore, the system, being aware of the situation, would not interfere with the vehicle operator taking an evasive action. The evasive path may be defined as a curvature which changes as a sinusoidal mathematical function of the position of the vehicle along the path. The control system may be based on a yaw rate control or a vehicle side slip angle control.
