ABSTRACT:
In an object detecting system for a vehicle to detect an object in accordance with the result of a search operation of the radar, and to allow detection of a deviation of the radar search direction irrespective of the vehicle traveling condition. The stationary object decision unit detects whether or not an object recognized by the object recognition unit as a result of the search operation of the radar is a stationary object. The moving locus of the object, which was determined to be stationary, relative to the vehicle is predicted by the locus prediction unit based on the detected value produced by the motion state detection unit. The actual moving locus of the object, determined as a stationary object, as observed from the vehicle is calculated by the actual locus calculation unit. The predicted value produced by the locus prediction unit and the calculated value produced by the actual locus calculation unit are compared by the comparison device. Based on the result of this comparison, the improper state decision unit decides whether the radar is in an improper state or not.
