An object detecting system for a vehicle detects an object based on output data from a distance sensor mounted on the vehicle. The distance sensor is capable of detecting a distance between the subject vehicle and the object along longitudinal and lateral directions of the subject vehicle. The output data from the distance sensor is associated on XY coordinates having a Y axis indicative of the longitudinal direction of the subject vehicle and an X axis indicative of the lateral direction with the respect to the subject vehicle in a coordinate developing device. The number of output data from the distance sensor which are located in a plurality of cells, defined by dividing the XY coordinates at predetermined distances in the X-axis and Y-axis directions and the XY coordinates for every cell, are output as cell information from a cell dividing device. In an object discerning device, the same labels or identifiers are assigned to the cells adjacent to one another, based on the cell information output from the cell dividing device, and barycentric position coordinates for every label are determined. Thus, it is possible to shorten the time required for a proximity determining process, while avoiding a reduction in accuracy of the coordinates of the object.
