  • Patent number: 11713977
    Abstract: An information processing apparatus includes an update unit and an obtaining unit. The obtaining unit obtains a second position of a map feature point included in map information based on the map information and information obtained from a vehicle sensor. The map information includes a map feature point first position measured in an environment including a closed route along which the vehicle travels. The sensor-obtained information includes a sensor feature point measured by the sensor mounted on the vehicle while the vehicle travels along the closed route. Where a distance between an estimated vehicle first position and an estimated vehicle second position is greater than a threshold, map information updating is restrained. Where the vehicle traveling near the vehicle first position continues traveling along the closed route, the update unit updates the map information between when the vehicle leaves the vehicle first position and nears the vehicle second position.
