Abstract: Provided is an electronic control device that estimates a presence of a vehicle incapable of performing vehicle-to-vehicle communication ahead of a communication partner vehicle is estimated.
An electronic control device 30 detects, on map data, an intersection 60 located ahead in a traveling direction of a host vehicle 10 based on location data and the map data of the host vehicle 10, calculates a stop position (first position) 71 where a communication partner vehicle 11 is supposed to pass through or stop when the communication partner vehicle 11 stops at the intersection 60, based on vehicle information of the communication partner vehicle 11 that is traveling toward the intersection 60, and determines whether or not there is another vehicle 13 ahead in the traveling direction of the communication partner vehicle 11, based on the stop position (first position) 71 and an intersection area 20 (second position 72) set before the intersection 60.-

Abstract: Realized is a vehicle control device capable of performing automatic driving control that does not reduce turning accuracy of a host vehicle even when an object in a blind spot is different from an assumption and a vehicle speed decreases due to a rapid deceleration. A vehicle control device 10 includes a blind spot object estimation unit 24 that detects a blind spot region 320 of an external-field recognition sensor 12 that recognizes an external field and estimates a blind spot object 310 potential in the blind spot region 320, and a future trajectory generation unit 26 that generates a future trajectory of a host vehicle in consideration of a potential risk from the blind spot object 310 estimated by the blind spot object estimation unit 24 and surrounding information of a vehicle 1 that is the host vehicle. Furthermore, the vehicle control device 10 includes a target steering angle calculation unit 40 that calculates a curvature radius at which the vehicle 1 travels from the future trajectory generated by the future trajectory generation unit 26 and a past trajectory of the vehicle 1, and calculates a target steering angle of the vehicle 1 from the calculated curvature radius and an acceleration/deceleration of the vehicle 1.

Abstract: An object of the present invention is to obtain a host vehicle position estimation device capable of estimating a highly reliable traveling road. The present invention relates to a host vehicle position estimation device (100) that estimates a position on a map of a host vehicle using information of an autonomous navigation position calculated based on vehicle information (102) and output of an inertial sensor (101), and information of a positioning position acquired from a positioning satellite, and corrects the autonomous navigation position to a position of a road on the map at predetermined travel distance intervals when the information of the positioning position is unavailable. The host vehicle position estimation device (100) includes a correction determination unit (12) that determines whether or not to perform the correction based on a position and an orientation of the host vehicle traveling on the road.
