Title: Parking space detecting device for vehicle
Inventor: KUBOTA TOMOKI
IPC: G01S15/93
Filed: 1999-10-26
Abstract: PROBLEM TO BE SOLVED: To provide a parking space detecting device for a vehicle capable of accurately detecting a parking space. SOLUTION: The distance to a detected object is measured by an ultrasonic sensor 14. The color of the detected object is detected by a CCD image sensor 12, and a vehicle and a parking space are discriminated by the color difference between them. The sampling distance between a vehicle position Xp changed in the measured distance and a vehicle position Xc changed in color is corrected. In the case of detecting both changes in the order of distance change and color change, the distance between Xp-Xc is corrected to the distance measured before the distance change is detected. In the case of detecting distance change after color change, the distance between Xc-Xp is corrected to the distance measured when (after) the distance change is detected.  The accurate position relation between one's own vehicle and vehicles around can be monitored inside the vehicle using the distance sensor 14 and CCD image sensor 12 to lighten a driver's burden in parking.
