Abstract: A travel storage system includes: a target vehicle behavior determination unit that is configured to: acquire a sensor value indicative of a behavior of each of surrounding vehicles around the host vehicle; and sequentially determine a relative behavior of a target vehicle with respect to the host vehicle based on the sensor value; a rule acquisition unit that acquires an accident liability rule in a current position of the host vehicle; a potential accident liability information determination unit that sequentially determines, using liability determination information, potential accident liability information indicative of whether the host vehicle is liable for a potentially assumed accident between the target vehicle and the host vehicle; and a storage unit that stores the potential accident liability information and the liability determination information in association with each other or in associable with each other.

Abstract: An automatic drive device includes a fusion unit recognizing travel environment of a vehicle based on an output signal of a surrounding monitoring sensor and a control planning unit generating a control plan based on a recognition result of the fusion unit. A diagnostic device includes an abnormality detection unit that detects an abnormality of a field recognition system from the surrounding monitoring sensor to the fusion unit by monitoring the output signal of the surrounding monitoring sensor and the recognition result of the fusion unit over time. The diagnostic device requests the control planning unit to perform MRM based on a detection of the abnormality of the recognition system by the abnormality detection unit.

Abstract: An aircraft control system is provided to include an unmanned aircraft, a retroreflective member, an installation base, a retroreflective member driver, and a survey instrument. The retroreflective member reflects light to an emission source. The installation base is provided integrally or separately with the aircraft; on the installation base, the retroreflective member is installed. The retroreflective member driver drives the retroreflective member so as to be movable relative to the installation base. The survey instrument tracks the retroreflective member based on the light reflected by the retroreflective member and surveys a distance to the retroreflective member and an angle of the retroreflective member, providing a survey result. Herein, a latest flight orientation of the aircraft is estimated from (i) a movement trajectory of the retroreflective member acquired from the survey result and (ii) a change in the flight orientation of the aircraft.
