CONSTITUTION:A reflecrive photoelectic sensor 2 which detects an object with out contacting with it and a mechincal bumper 2 which detects the object with contacting are arranged. The input signal of this photoelectric sensor 2 is branched, and one is applied to an OR element 514 as it is, and the other is applied to the element 514 through a timing element T. A controller 5 is provided which is released from the deceleration control if the bumper 3 is not operated over a certain time from the operation of the photoelectric sensor 2. By this constitution, running is continued even if the person who crosses the path of the unattended car is detected or the object is detected temporarily during the change of direction of the unattended car. |
