A map information output device includes: a rule selector sequentially selecting one road selection rule from a plurality of road selection rules based on route guidance information; a target road selector for (i) selecting a target road for constructing control map information based on the road selection rule selected by the rule selector and a position of a vehicle, and (ii) selecting another target road for constructing control map information based on another road selection rule different from the road selection rule selected by the rule selector, respective for automatic drive control; a map information constructor sequentially constructing the control map information; and a map information output unit sequentially outputting the control map information, which determines the control map information to be output based on whether or not the vehicle is traveling on a route to be traveled.

Map information output device and method to output and select control map information

A map information output device including a map information output unit that outputs control map information for automatic driving control of a vehicle to an automatic driving control unit The map information output device includes: a map storage unit storing an original map for constructing the control map information; a position obtainer obtaining a current position of the vehicle; a map information constructor sequentially constructing the control map information based on the original map of a first range determined with reference to the current position obtained by the position obtainer; and a download processor downloading and storing the original map of a second range, which is a range determined based on the current position and includes the first range, sequentially from a map distribution device outside the vehicle by wireless communication.

Map information output device, automatic driving control system, map information output system, and map information output method

A vehicle controller includes a memory configured to store map information including information on a predetermined area used in autonomous driving control of a vehicle; and a processor configured to: refer to the map information to identify an autonomous-driving practicable point at which a planned travel route from the current position of the vehicle outside the predetermined area to a destination of the vehicle enters the predetermined area, calculate a manual-driving section length from the current position of the vehicle to the autonomous-driving practicable point along the planned travel route, and notify the calculated manual-driving section length to a driver of the vehicle via a notification device provided in the interior of the vehicle.

Vehicle controller, and method and computer program for distance notification

A travel controller detects a non-lane zone within a predetermined distance ahead of a current position of a vehicle. The non-lane zone lacks lanes. The travel controller controls travel of the vehicle in the non-lane zone so as to keep the position of the vehicle relative to the width of a whole road. When an expected position of the vehicle at the end of the non-lane zone straddles a lane line, the travel controller controls travel of the vehicle so as to move to a lane having a larger overlap with the vehicle, prior to control of travel of the vehicle to keep the position of the vehicle relative to the width of the whole road.

Travel controller and method for travel control

A map information assessment device has a processor configured to match a plurality of first zones representing a first road in a first map, with second zones representing a second road in a second map, the matching being made by using locations on the second road that are closest to the starting points of the first zones as the starting points, and using zones having the same lengths as the first zones, as the second zones corresponding to the first zones, to calculate zone adjacent distances between the end points of the second zones and the starting points of other second zones adjacent to those second zones, and to determine that positional information for the first road in a first zone is different from positional information for the second road in a second zone corresponding to that first zone, when the zone adjacent distance is greater than a threshold.

Map information assessment device, storage medium storing computer program for map information assessment, and map information assessment method

A route selection device includes a processor configured to identify a position of a lane on which a vehicle is traveling; search for candidate partial routes leading from a current position of the vehicle to a waypoint on a route leading from a start point to a destination, the waypoint being located between the current position and the destination; determine a lane change location where a lane change will be made for each of the candidate partial routes found by searching; and select, as a partial route, a candidate partial route having a minimum total score regarding the lane change location from the candidate partial routes found by searching. The score is weighted depending on the position of the determined lane change location or whether a lane change at the lane change location can be controlled by a travel controller.

Route selection device and method

A road zone assessment device has a processor configured to select a first road zone from among multiple first road zones representing a first road associated with a vehicle navigation route, and connected with a second road zone representing a second road different from the first road, on a location-estimating map used for a vehicle, to determine whether or not the navigation route extends from the selected first road zone to the second road zone, to identify other first road zone associated with the navigation route from the selected first road zone forward on the destination location side of the navigation route, and to release association between the other first road zone and the navigation route when the selected first road zone is connected with the second road zone and the navigation route extends from the selected first road zone to the second road zone.

Road zone assessment device, medium storing computer program for road zone assessment, and road zone assessment method

A map information assessment device has a processor configured to detect the end road zone located furthest on the destination location side, among the multiple road zones on the navigation route, to determine whether or not the end road zone is connected to another road zone on the destination location side, to detect the end road link on the navigation route which is associated with the end road zone when the end road zone is connected with another road zone on the destination location side, and to determine whether or not the end road link is connected with another road link representing the navigation route, which is not associated with the road zone on the destination location side, and to attach a predetermined attribute to the end road zone when the end road link is connected with another road link representing the navigation route.
