Abstract: A vehicle behavior generation device sets multiple possible behaviors of an own vehicle when the own vehicle travels along a planned route; sets multiple possible behaviors of a different vehicle existing around the own vehicle corresponding to each of the set multiple possible behaviors of the own vehicle; outputs information indicating a contact possibility between the own vehicle and the different vehicle for each of combinations of the set multiple possible behaviors of the own vehicle and the set multiple possible behaviors of the different vehicle; and selects one of the multiple possible behaviors of the own vehicle based on the outputted information.

Abstract: A vehicle behavior evaluation device: sets multiple possible behaviors of an own vehicle when the own vehicle travels along a planned route; generates, using a function device, traveling situation related reward data by learning; calculates, using the function device, a reward to each possible behavior of the own vehicle by considering a traveling state of different vehicle; and evaluates each possible behavior of the own vehicle based on the calculated reward. The traveling situation related reward data is generated by: simulating multiple combinations of situations of the own vehicle and the different vehicle under different environments; assigning a first reward to a first situation of the own vehicle when the own vehicle avoids a contact with the different vehicle; and assigning a second reward that is lower than the first reward to a second situation of the own vehicle when the own vehicle contacts with the different vehicle.

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.
