  • Publication number: 20240149640
    Abstract: A vehicle air conditioning system includes a refrigerant circuit, a heat medium circuit, a vehicle-interior heat exchanger, a vehicle-exterior heat exchanger including a first heat exchanger and a second heat exchanger disposed in series with respect to a flow of air generated by an air blower, a switching unit, a detection unit for detecting a degree of frost formation, and a control device. The operation mode includes a defrosting mode in which the heat medium in the high-temperature medium circuit is supplied to a defrosting target to be selected as either the first or second heat exchanger by the operation of the switching unit. The control device selects, as the defrosting target, the first heat exchanger in preference to the second heat exchanger when determined that both the first and the second heat exchangers need to be defrosted.

  • Patent number: 11383814
    Abstract: A sensor that detects a shape of a surrounding environment of a boat and a positional relationship between the surrounding environment and the boat body outputs environment information indicating the shape of the surrounding environment and the positional relationship. A display displays an environment map indicating the surrounding environment. An input accepts an input of a shore arrival target position of the boat body on the environment map and outputs target position information indicating the shore arrival target position. A controller receives the environment information and the target position information, determines a possible shore arrival space of the boat body in the surrounding environment based on the environment information, and corrects the shore arrival target position based on the possible shore arrival space. The controller generates an instruction signal to control a propulsion device so as to cause the boat body to arrive at the shore at the corrected shore arrival target position.

  • Patent number: 11243538
    Abstract: A positional sensor detects a current position and a current bearing of a boat body and outputs position information indicating the current position and the current bearing. A controller receives the position information. The controller determines a first target position of the boat body and a target bearing in the first target position. The controller calculates a bearing difference between the current bearing and the target bearing. The controller determines an offset amount of the first target position in response to the bearing difference or an outside disturbance. The controller determines a position spaced away by the offset amount from the first target position on a side toward the current position as a second target position. The controller generates an instruction signal to control a propulsion device so as to cause the boat body to arrive at the second target position.

  • Patent number: 11167833
    Abstract: A first sensor detects first environment information indicating a shape of a shore arrival location and a positional relationship between the shore arrival location and a boat body. A second sensor, different from the first sensor, detects second environment information indicating the shape of the shore arrival location and the positional relationship between the shore arrival location and the boat body. A controller is communicatively connected to the first sensor and the second sensor. When the distance from the boat body to the shore arrival location is greater than a predetermined distance threshold, the controller generates, based on the first environment information, an instruction signal to control a propulsion device to as to cause the boat body to arrive at the shore arrival location. When the distance from the boat body to the shore arrival location is equal to or less than the distance threshold, the controller generates an instruction signal based on the second environment information.
