Automatic driving support system, automatic driving support method, and map data structure for data for automatic driving

摘要

To enable the provision of map data suitable for automatic driving.SOLUTION: An automatic driving support system includes: a storage device 13 for storing map data including division lines; an external sensor for detecting surround information of a vehicle; and a control unit 11 for controlling traveling of the vehicle while calculating a relative positional relation between the vehicle and a division line on the basis of the surround information detected by the external sensor and map data 130. The map data includes a lane network generated by connecting point sequences passing through the center of a traffic lane, and multiple pieces of division line data associated with the lane network. A standard deviation of a distribution of errors is within 12.5 cm for the errors of distances between positions in a horizontal cross section of arbitrary two pieces of division line data located within a fixed range from an arbitrary reference point on the lane network among the multiple pieces of division line data.SELECTED DRAWING: Figure 1
