Abstract: A method of manufacturing a solid-state battery includes forming an electrode that includes a first electrode layer and a second electrode layer facing the first electrode layer and that further includes a buried layer interposed between the first electrode layer and the second electrode layer so as to surround a contact portion where these electrode layers contact each other. For the buried layer, a solid electrolyte with lower electron conductivity than an electrode active material is used, for example. The buried layer is provided between the edge portion of the first electrode layer and the edge portion of the second electrode layer, so that deformation of the first electrode layer and second electrode layer is prevented in the subsequent lamination and thermocompression bonding and thus the occurrence of a short circuit due to such deformation is prevented in the solid-state battery.

Abstract: An automotive arithmetic system includes a main arithmetic device that determines a target motion of a motor vehicle so that the motor vehicle travel on a route generated based on a vehicle external environment estimated using deep learning based on an output from a vehicle external information acquisition device; and a backup arithmetic device that determines a backup target motion for causing the motor vehicle to travel on a travel route which is generated based on the output from the vehicle external information acquisition device and which the traveling motor vehicle takes until the motor vehicle stops at a stop position that satisfies a preset criterion. The automotive arithmetic system outputs a backup control signal to actuators in preference to a control signal when the main arithmetic device fails.

Abstract: An automotive arithmetic device includes circuitry that calculates a first candidate route based on a vehicle external environment estimated using deep learning; sets a static safe area (SA2) based on a result of recognition of a target object outside a vehicle according to a predetermined rule; and determines a target motion of the motor vehicle. The circuitry selects the first candidate route as a travel route of the motor vehicle under a condition the first candidate route is entirely within the static safe area (SA2), and does not select the first candidate route as the travel route of the motor vehicle when the first candidate route at least partially deviates from the static safe area (SA2).
