Abstract: A road information detector acquires road information by emitting a beam via a variable directivity transmission antenna to a road sign having plural flat portions and includes a transceiver that controls the antenna to scan the beam by switching an emission angle including an azimuth angle relative to the front direction of a vehicle and receives, as reflected wave signals, waves reflected by the flat portions, a distance and reflected wave intensity detector that detects a distance between the vehicle and each of the flat portions and a reflected wave intensity of each of the reflected waves, an emission angle detector that detects the emission angle based on the reflected wave signal, and a road information analyzer that acquires the road information by generating a heat map based on the emission angles, distances, and reflected wave intensities and analyzing the heat map using a threshold value of the wave intensity.

Abstract: In a radar device mounted in a host vehicle, a radar transmitting unit transmits a radar signal; a light detection unit detects ON or OFF of a light of another vehicle in which the radar device is mounted; and a timing control unit sets a transmission timing of the radar signal and a light ON timing of a light of the host vehicle, the light ON timing is synchronized with the transmission timing on basis of detected ON or OFF of the light of the other vehicle. The set transmission timing is different from a transmission timing of a radar signal of the radar device mounted in the other vehicle.

Abstract: A driving lane detection device of the present disclosure includes: an object detector, a vehicle detector, and a driving lane detector. The object detector generates object data relating to a distance and direction from the vehicle to an object and a movement direction of the object based on one or more reflection waves that are a radar signal transmitted by a radar device and reflected by the one or more object. The vehicle detector detects each object as at least one of a parallel-running vehicle running in a same direction as the vehicle or an oncoming vehicle running in an opposite direction to the vehicle, based on the object data. The driving lane detector detects a driving lane based on the distance and direction from the vehicle to at least one of the detected parallel-running and the detected oncoming vehicles and lane information on at least one of lane widths and a number of lanes of a road on which the vehicle is running.
