Abstract
A detection apparatus determines the type of an object approaching a vehicle. The detection apparatus is provided on a bumper of the vehicle, and comprises a coil as well as electrode lines to serve as the electrodes of a capacitor for detecting a human body. The detection apparatus is capable of differentiating a metallic body and a human body from each other based on variations in output voltage, which are caused by changes in their impedance.
