摘要
There is provided a scan type radar device for a vehicle 52 which determines very accurately whether an object 54 detected by a radar is in a lane in which a radar-equipped vehicle 52 moves, while restraining an increase in manufacturing cost of the radar device. The scan type radar detects objects existing within the detectable range, the scan type radar device estimates the vehicle movement lane area 4 corresponding to the vehicle movement lane on which the vehicle 52 moves based on the vehicle operation condition, The vehicle moving lane area is estimated within the detectable range. The actual direction ([theta] cent ) of each object is detected by the scan type radar with respect to the radar mounted vehicle 52. [ The delay method ([theta] cent FILT) is calculated when the actual direction detected by the object direction detecting device is changed with time. The delay direction indicating the virtual position direction of each object 54 to the vehicle is changed Lt; / RTI It is determined whether or not each object 54 is in the vehicle movement lane based on the delay direction? Cent FILT.
