Abstract: A vehicle control system capable of ensuring safety at a low cost even when a control device fails, includes a first control device that implements at least two automatic driving-related functions based on information from external sensors and/or information from a map database, a second control device that implements fewer automatic driving-related functions than the first control device based on the information from the sensors and/or the map database, and a vehicle motion control device that automatically controls a driving state of a host vehicle based on a function planned by the first or second control device including: a backup determination unit that determines whether the future function planned by the first or second control device is backed up by the second control device; and an interface that notifies a driver that system responsibility is switched to the driver, when the backup is not available.

Abstract: An electronic control device includes: an object recognition unit that recognizes surrounding objects based on external environment information acquired by an external environment sensor; an obstacle object generation unit that generates an obstacle object regarding an object that generates a blind spot region by shielding observation by the external environment sensor among the recognized objects; and a blind spot object management unit that manages, as a blind spot object, a blind spot region generated by the obstacle object, in which the object recognition unit generates solid object information regarding an object that can enter and exit the blind spot region among the recognized objects, and the blind spot object management unit associates a solid object that has entered the blind spot region with a blind spot object in the blind spot region, and cancels association of a solid object that has exited the blind spot region with a blind spot object in the blind spot region.

Abstract: A memory stores an assistance pattern including a first periphery sensor map indicating a map in a periphery of a vehicle and an assistance content of driving assistance of the vehicle corresponding to the first periphery sensor map. A processor (sensor information acquisition unit 101) acquires sensor information indicating information on an object in the periphery of the vehicle sensed by a sensor. A processor (periphery sensor map acquisition unit 102) acquires a second periphery sensor map based on the sensor information. A processor (map similarity search unit 103, and assistance instruction unit 104) performs driving assistance of the assistance content corresponding to the first periphery sensor map when the second periphery sensor map is similar to the first periphery sensor map.

Abstract: Provided are a self-map generation device and a self-position estimation device with which it is possible to achieve high-accuracy self-position estimation even when an observation error due to a sensor is large by estimating an error amount of a landmark serving as an observation point and improving the quality of a self-generated point group map. This self-map generation device generates a point group map from point group data of external information obtained by a vehicle-mounted sensor mounted in a vehicle, and comprises: a landmark detection unit that detects a landmark from the point group map; a landmark information accumulation unit that accumulates observation position information of the detected landmark; a landmark position correction unit that corrects the position of the landmark on the basis of point group coordinates extracted from an error distribution detected when the observation position information of the landmark has been frequency-distributed; and a self-map generation unit that saves, as a self-generated map, a corrected map obtained by correcting the position of the landmark and obtained from the landmark position correction unit.

Abstract: A vehicle control device that autonomously controls a vehicle so as not to cause rapid deceleration that leads to a deterioration in ride quality. The vehicle control device controls first and second deceleration, means that reduce a speed at a deceleration rate large than a deceleration rate of the first deceleration means. The vehicle control device includes a blind spot area detecting unit that detects a blind spot area of a sensor that recognizes an external environment, and a blind spot object estimating unit that estimates a blind spot object that is a virtual moving body hidden in the blind spot area. When a vehicle approaches the blind spot area at a speed reduced by the first deceleration means, the vehicle is decelerated by the second deceleration means when a type of a moving body detected by the sensor is different from a type of the blind spot object.
