ABSTRACT:
A vehicle obstacle detecting apparatus has an obstacle sensor, an obstacle detecting section, a vehicle response section, a driver operation storing section, a precision determining section and a threshold value updating section. The obstacle detecting section is configured to determine a presence of an obstacle around the vehicle to output a positive obstacle determination based on a similarity value between the detected obstacle information sent from the obstacle sensor and pre-stored obstacle detection reference information with a threshold value. The driver operation storing section is configured to store an average operation characteristic data calculated based on a driver operation. The precision determining section is configured to determine a detection precision of the obstacle by comparing an expected driver operation determined based on the average operation characteristic data with an actual driver operation. The threshold value updating section is configured to adjust the threshold value based on the detection precision.
