Provided are a detection and recognition step for determining whether the object is in motion and a control step for controlling in dependence on the output of the detection and recognition step a time interval at which a distance measuring step for measuring a distance to the object is performed in such a manner that the time interval for the stationary object is longer as compared with the case where the object is moving, whereby energy consumption is suppressed to a minimum.
