Patent Images
1. A driving support system comprising:
- information amount determining means for determining an amount of visual information of objects, which need to be recognized by a driver for safe driving of a vehicle;
information acquisition capacity setting means for estimating a level of the driver in acquiring visual information and setting the estimated level as a visual information acquisition capacity of the driver;
driving support means for providing support to the driver in driving the vehicle;
driving support level setting means for setting a level of driving support provided by the driving support means based on the visual information amount and the visual information acquisition capacity;
object detecting means for detecting objects around the vehicle; and
object selecting means for selecting objects necessary to be recognized by the driver for safe driving from the detected objects and determining a number of selected objects, wherein the information amount determining means determines the amount of visual information based on the number of the selected objects.

Abstract
In a driving support system, a necessary information amount determining section determines the amount of visual information necessary for safe driving. An information acquisition capacity setting section sets an information acquisition capacity of a driver. A comparing section compares the necessary information amount with the information acquisition capacity and determines a difference between the two. If a possibility of collision between an object and a vehicle is determined by a collision possibility determining section, a driving support level setting section sets a level of driving support based on the difference.
