Abstract: A reporting device that is connected to at least one vehicle, which is controlled based on a result of recognition by an outside recognizer, via a network provides the vehicle with information on a possibility of a failure in outside recognition on the basis of a condition under which a failure in outside recognition has occurred previously. Preliminarily, if a failure such as non-detection or erroneous detection occurs due to an outside recognizer of a connected car, the abnormality is stored while being linked with an external traveling environment such as the position of the vehicle or a weather.

Abstract: In a dielectric ceramic having crystal grains and containing a perovskite in which the A site contains Ba and the B site contains Ti. as a main component, the crystal orientations are aligned in substantially the same direction within the crystal grains. Some of Ba may be replaced with Ca and/or Sr, and some of Ti may be replaced with Zr and/pr Hf. This achieves a dielectric ceramic which has a high dielectric constant and has favorable AC electric field characteristics in which the change in dielectric constant is small even with changes in applied electric field.
