A vehicle control system includes an integration unit that estimates information on a position and a speed of a target existing in an external field, and errors of the position and the speed based on information from a sensor that acquires information on the external field of an own vehicle. The integration unit estimates an error of a detection result from the detection result of a sensor that detects an external field of a vehicle in accordance with a characteristic of the sensor, determines correlation between detection results of a plurality of the sensors, and integrates correlated detection results and calculates the errors of the position and the speed of the target.-

Abstract: An axial deviation of the sensor is corrected. An aiming device that calculates a correction parameter for correcting a detection result of a target sensor includes an estimated-track generation unit that detects a track of a target for a period when an own vehicle moves, by using information of a movement of the own vehicle, which is detected by a movement sensor, and generates a plurality of estimated tracks having different start-point positions from the detected track of the target by using a first variable group, a corrected-track generation unit that generates a plurality of corrected tracks from the track of the target around the own vehicle, which is detected by the target sensor, by using a second variable group, and a correction parameter calculation unit that selects a combination in which a difference between the estimated track and the corrected track is small, and calculates the correction parameter for correcting a displacement of the target sensor by using a first variable related to the selected estimated track and a second variable related to the selected corrected track.

Abstract: A method determines the region where a vehicle can travel without changing clarity of the position information of the object detected by a sensor. An in-vehicle control device includes an object detection unit detecting the position of an object from image information captured by an image pickup device, an object information storage unit stores a pre-processing grid map including a position of a detected object set as an object occupied region and a position where no object has been detected is as an object unoccupied region, an information processing unit generates a determination grid map in which part of the object unoccupied region of the map is replaced with the object occupied region, and a road surface region determination unit that generates an automatic driving grid map in which a closed space surrounded by the object occupied region of the determination grid map is set as a road surface region.

Abstract: A vehicle control system includes an integration unit that estimates information on a position and a speed of a target existing in an external field and errors of the position and the speed of the target, based on information from a movement sensor that acquires movement information including a vehicle speed and a yaw rate of an own vehicle, and information from an external field sensor that acquires information on the external field of the own vehicle. The integration unit uses not the information from the external field sensor, but the vehicle speed and the yaw rate acquired by the movement sensor, to predict a position and a speed of the target and errors of the position and the speed of the target at a second time after a first time, from a position and a speed of the target and errors of the position and the speed at the first time.

Abstract: Provided is a vehicle control system capable of grouping objects detected by a plurality of sensors with high accuracy in a short time. A vehicle control system 100 includes an information integration device 120 that groups first detection information and second detection information of a first sensor 111 and a second sensor 112 and outputs integrated detection information, and a vehicle control device 130 that controls a vehicle on the basis of the integrated detection information. An arithmetic device 121 of the information integration device 120 stores first time-series information of the first detection information and second time-series information of the second detection information in a storage device 122, calculates a correction parameter of the first detection information by grouping the first time-series information and the second time-series information when the first sensor 111 and the second sensor 112 detect the same object, calculates correction information obtained by correcting the first detection information using the correction parameter, and outputs the integrated detection information by instantaneous value grouping using the correction information and the second detection information.

Abstract: This on-vehicle system is to be mounted in a vehicle and is provided with an electronic control device and an externality recognition sensor. The externality recognition sensor is equipped with a sensing unit for acquiring pre-processing externality information through sensing operations. The on-vehicle system is further equipped with: a condition calculation unit that, on the basis of a vehicle position, a vehicle traveling direction, and map information, calculates a processing condition in which information specifying an area on a map is associated with processing priority of the pre-processing externality information acquired by the externality recognition sensor; and a processing object determination unit that, on the basis of the pre-processing externality information and the processing condition, creates externality information having a smaller amount of information compared with the pre-processing externality information.
