Abstract
In a ranging sensor system for a vehicle for calculating a physical data between a subject vehicle and an object on the basis of the time between the transmission of a signal toward the object and the reception of a signal reflected from the object, a first obtained detection data is set as an offset value in an offset value setting circuit. The offset value is subtracted from the detection data in a subtractor, and an output from the subtractor is filtered in a filter circuit. The offset value is added to an output from the filter circuit in an adder to provide a physical data after the filtering. Thus, it is possible to eliminate an error included in detection data, while insuring a responsiveness and a stability.
