发明名称 Object detection apparatus for a vehicle
摘要 An object detection apparatus for a vehicle includes a light emitter covered with an emission window, a light receptor covered with a reception window, a defect detection light emitter, a defect detection light receptor and a fracture detection circuit. The light emitter emits a light in front of the vehicle. The light receptor receives the light reflected by an object. The defect detection light emitter emits a detection light into one side of at least one of the emission and reception windows. The defect detection light receptor receives the detection light transmitted through the at least on emission and reception windows at another side. The fracture detection circuit determines whether either of the emission and reception windows are fractured based on the detection light received by the defect detection light receptors.
