  • Publication number: 20220277402
    Abstract: Estimation of the range of activities of a target user is enabled in a relatively narrow range. A target user whose location is to be calculated has an account in social media. An offline friend determination means (111) calculates an offline friendship level on the basis of friend information obtained from at least one social media account related to the target user. The offline friendship level is the degree of friendship in real space between the target user and the at least one social media account related to the target user. A friend weight calculation means (112) calculates a weight to be assigned to the friend information on the basis of the offline friendship level. A candidate location score calculation means (113) calculates a score representing the possibility of the target user being active at a candidate location on the basis of the friend information and the corresponding weight.

  • Patent number: 9876365
    Abstract: A contactless power supply system for transferring power without contact between a primary side coil and a secondary side coil is provided. In the contactless power supply system, a manipulation unit manipulates a secondary side converter so that power outputted to a load is controlled to be a command value. The manipulation unit manipulates an input voltage of a primary side resonance circuit so that a current flowing in the primary side resonance circuit equals a product of a current flowing in the secondary side resonance circuit and a current coefficient. The current coefficient is defined as a square root of a specific value and the specific value is an equivalent resistance of the secondary side resonance circuit divided by an equivalent resistance of the primary side resonance circuit.

  • Patent number: 9184633
    Abstract: A non-contact power supply control device controls power supply to transmit power in a non-contact manner from a ground-side power supply section provided outside a vehicle traveling using stored power to a vehicle-side power receiving section provided to the vehicle. A detection unit detects a living body at the periphery of the ground-side power supply section.

  • Patent number: 8823203
    Abstract: A waste heat controller controls waste heat quantity of an engine according to a required heat quantity along with a heat-utilize requirement. When the heat-utilize requirement is generated, a fuel-increase-rate indicating a fuel increase quantity is computed. A reference fuel-increase-rate is established to be compared with the fuel-increase-rate. Based on this comparison result, it is determined whether the waste heat increase control will be executed.

  • Patent number: 8612092
    Abstract: A request heat calculation unit calculates a request heat power requested to heat sources to supply. A heat cost calculation unit calculates a relationship between a heat power supplied from each of the heat sources and a heat cost, which is a fuel quantity consumed to supply a unit heat power. An abnormal source detection unit detects an abnormal heat source, which cannot normally supply a heat power, from the heat sources. An abnormal heat calculation unit calculates an abnormal heat power supplied from the abnormal heat source. A determination unit determines distribution of heat power supplied from the heat sources based on both the relationship and the abnormal heat power, such that a sum of the heat power supplied from the heat sources coincides with the request heat power, and the heat cost of all the heat sources is minimized.

  • Patent number: 8229615
    Abstract: A hybrid vehicle control ECU calculates an estimated EV travelable distance based on a minimum travel cost and a usable charge amount of a battery, when a next external charge point, at which an external power source is available for charging, is set. The minimum travel cost indicates a minimum value of electric power amount consumed by a battery when a vehicle travels a unit distance. If the estimated EV travelable distance is longer, electric motor travel is selected estimating that it is possible to reach the next external charge point. If a remaining distance is longer and a present SOC is higher than a usable SOC lower limit, hybrid travel is selected. If the present SOC is lower than the usable SOC lower limit, a constant SOC travel is selected.

  • Patent number: 8204638
    Abstract: A control apparatus for a hybrid vehicle computes estimated energy and external charge energy. The estimated energy is required to drive a vehicle to travel a planned travel route and an EV priority mode, in which drive power for the vehicle is generated with priority by a motor/generator by supplying electric power from a battery to the motor/generator. The external charge energy is supplied from an electric power source. The control apparatus checks whether the estimated required energy will be supplied fully by the external charge energy. If the full supply is not possible, the control apparatus causes electric power generation by the motor/generator at some point in the planned travel route, where the efficiency of electric power generation is good, thereby to supplement insufficiency of energy.
