The detection region to which the electromagnetic wave from a vehicle is transmitted ahead in a direction of movement of the vehicle in order to detect an obstacle such as another vehicle in front or the like, is composed of a first detection region looking slightly upward with respect to the road surface and a second detection region looking slightly downward with respect to the road surface. Received signal strengths of reflected waves in the first and second detection regions are compared with each other. When the two received signal strengths are substantially equal to each other, the vertical angle of the object detecting apparatus is judged adequate. When the received signal strength of the reflected wave in the upper-side, first detection region is larger, the angle is judged downward. When the received signal strength of the reflected wave in the lower-side, second detection region is larger, the angle is judged upward and the angle for attachment of the object detecting apparatus is adjusted automatically.

Power supply stand output to the portable device is adjusted according to the power adjustment signals. Maximum power supply stand output is limited to a power output threshold value. The portable device compares the power received from the power supply stand to the required power. When the received power is lower than the required power, the portable device sends a power adjustment signal to the power supply stand, which is an increase-power-request signal. When the received power is greater than the required power, the portable device sends a decrease-power-request signal to the power supply stand. The power supply stand adjusts output and limits it to the power output threshold value. When continuous output of increase-power-request signals from the portable device is detected over a preset time period, a foreign object is determined to be on the power supply stand.
