DRIVING ASSIST DEVICE
First Claim
1. A driving assist device comprising:
- a vehicle position detecting unit for detecting a position of a vehicle in a direction of a width of a road along which the vehicle is travelling by using both distance data on at least one of distances from both right and left side surfaces of the vehicle to an object to be detected which are detected by distance sensors mounted on both the right and left side surfaces of the vehicle for detecting the distances from the both side surfaces to an object, and road width data on the width of the road which is specified from map information by using vehicle position information;
a vehicle position correcting unit for determining a travelling path of the vehicle on a basis of wheel speeds of right and left wheels of at least one of front and rear wheelsets of said vehicle, the wheel speeds being detected by wheel speed sensors for detecting the wheel speeds of said right and left wheels, and for specifying distance data having a time-varying change equal to or larger than a predetermined threshold from among the distance data showing said vehicle position which is detected by said vehicle position detecting unit to correct the vehicle position in such a way that the vehicle position is shown by the distance data from which said specified distance data are removed when the travelling path of said vehicle shows a straight ahead movement;
a travelling state determination unit for determining a travelling state of said vehicle from a time-varying change of the vehicle position in the direction of the width of said road which is corrected by said vehicle position correcting unit; and
a notification unit for notifying a content according to the travelling state determined by said travelling state determination unit.

Abstract
A driving assist device detects the position of a vehicle 13 in a direction of the width of a road by using both distance data on both right and left sides of the vehicle and road width data on the width of the road, specifies distance data having a time-varying change equal to or larger than a predetermined threshold from among the distance data showing the vehicle position detected to correct the vehicle position in such a way that the vehicle position is shown by the distance data from which the distance data specified are removed when the travelling path of the vehicle 13 shows a straight ahead movement, determines the travelling state of the vehicle 13 from a time-varying change of the vehicle position corrected, and notifies a content according to the travelling state determined.
