Abstract: A state calculation apparatus includes an receiver that receives azimuths of objects around a vehicle and their relative velocities to the vehicle, detected by a first sensor used for the vehicle, as target information, and a velocity and a travel direction of the vehicle, detected by a second sensor installed on the vehicle and having an error variance, as state information, and a controller that calculates velocities and travel directions of the vehicle, using the state information and based on a plurality of the azimuths and a plurality of the relative velocities extracted from the target information and that outputs at least either a velocity or a travel direction of the vehicle by using a specified filter to filter mean values of and error variances in the calculated velocities and travel directions and at least either the velocity or the travel direction detected by the second sensor.

Abstract: A determination device includes: route detection circuitry which detects, a first continuous body as a first part of a one or more first direction distance information with respect to a first object, and a second continuous body as a second part of the one or more first direction distance information with respect to a second object, in a first direction along a first route on which the moving body moves, and a third continuous body as the second part, in a second direction; route determination circuitry which determines presence or absence of a second route along the third continuous body.

Abstract: There is provided a detection device that includes: a position estimator that estimates a candidate position of a crosswalk in a movement direction of a vehicle and estimates a length of the crosswalk and an intersecting angle between the crosswalk and a roadway using the candidate position; a corrector that corrects the numbers of periods and widths of two basis functions based on the estimated length of the crosswalk and the estimated intersecting angle, the two basis functions corresponding to intervals of white lines of the crosswalk and are orthogonal to each other; and a crosswalk detector that detects whether or not the crosswalk is present using both image data which include the candidate position and the two corrected basis functions.

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 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.
