Abstract: High temperature (HT) and low temperature (LT) cooling water, the LT cooling water being at a lower temperature than the HT cooling water, circulate in HT and LT cooling water flows in respective channels. A controller controls to set the temperature of the LT cooling water lower in a case where an operating point of an engine lies in a particular region in an operational region of the engine, the particular region including a region in which the load is high and the engine speed is low, than in a case where the operating point lies in an operational region other than the particular region. Furthermore, the controller narrows the particular region in a direction toward higher loads in a case where the temperature of the HT cooling water is lower than a predetermined temperature.

Abstract: A battery cooler comprises a refrigerant filling chamber, a refrigerant inflow passage, and a refrigerant outflow passage. The refrigerant filling chamber is sandwiched between opposed battery unit cells and is arranged at a position for receiving heat of the unit cells. The refrigerant inflow passage is connected to a lower portion of the refrigerant filling chamber. The refrigerant outflow passage is connected to an upper portion of the refrigerant filling chamber. The refrigerant filling chamber has at least one joint part joining partially and mutually opposed wall surfaces so as to suppress expansion and deformation of these surfaces caused by the pressure of the refrigerant. An outflow side wall surface rises from a bottom surface of the refrigerant filling chamber toward a connection part of the refrigerant outflow passage. The outflow side wall surface is provided with an inclined surface directed downward from a horizontal direction.

Abstract: A management system manages an environment of a predetermined area. In the predetermined area, there are a recognition sensor configured to recognize a surrounding situation and a recognition target to be recognized by the recognition sensor present at a specific position. Three-dimensional map data of the predetermined area include specific space information indicating a specific space that is a space between the specific position and the recognition target. Recognition result information indicates a result of recognition by the recognition sensor present at the specific position. The management system determines whether an object not included in the specific space in the three-dimensional map data is included in the specific space in the recognition result information. The management system detects, as a removal target, the object not included in the specific space in the three-dimensional map data but is included in the specific space in the recognition result information.
