An apparatus for emotion estimation sets a face feature threshold based on a plurality of face features indicating a deviation from a reference state of a predetermined part of a face detected from each of a plurality of face images representing a face of a driver of a vehicle generated by a camera mounted on the vehicle in a predetermined time range, specifies face features larger than the face feature threshold among the plurality of face features detected from each of the face images generated by the camera at a time not included in the predetermined time range, and estimates an emotion of the driver by using normalized features obtained by normalizing the specified face features downward.

Apparatus and method for emotion estimation

An apparatus for determining a driver's behavior includes a processor configured to detect a looking direction of a driver of a vehicle, based on an image obtained by a camera provided to capture the interior of the vehicle, calculate an angle formed between the looking direction and a normal direction of an operation screen of a portable device in the vehicle, the normal direction being indicated by information received from the portable device via a communication device capable of communicating with the portable device, and determine that the driver is operating the portable device when the angle is within a predetermined angle range.

Apparatus, method, and computer program for determining driver's behavior

A travel controller detects objects from an environmental image representing surroundings of a vehicle capable of traveling under autonomous driving control satisfying a predetermined safety standard; detects a looking direction of a driver of the vehicle from a face image of the driver; identifies an object in the looking direction of the driver out of the objects; stores the identified object and a situation condition indicating the situation at detection of the identified object in a memory in association with each other when a danger avoidance action performed by the driver is detected during travel of the vehicle; and changes the predetermined safety standard so that the driver can feel safer, in the case where an object stored in the memory is detected during travel of the vehicle under the autonomous driving control and where the situation at detection of the object satisfies the situation condition.

Travel controller and method for travel control

A fuel cell system includes: a first tank and a second tank each accumulating a fuel gas to be supplied to a fuel cell; a heating device disposed in a passage connecting the first tank and the second tank; and a controller configured to bring the heating device into operation so that the fuel gas flowing from one of the first tank and the second tank to the other of the first tank and the second tank through the heating device is heated when a condition for a temperature of the fuel gas in the first tank or a condition for a temperature of the fuel gas in the second tank is satisfied.
