  • Publication number: 20240097467
    Abstract: The power reception control device is configured to: acquire information indicating differential power obtained by subtracting a current value of total transmission power transmitted to an entirety of a load group via a power supply base point, from a maximum value of the total transmission power transmittable to the entirety of the load group via the power supply base point; calculate element differential power of an own power receiving element by multiplying the differential power indicated by the acquired information by a priority of the own power receiving element, the priority indicating a degree to which power reception of the own power receiving element takes priority over power reception of another power receiving element; and control charging-discharging of the own power receiving element based on the element differential power and a charge-discharge schedule of a power system.

  • Patent number: 11932258
    Abstract: A vehicle body speed estimation device and a vehicle body speed estimation method are provided for estimating a vehicle body speed of a four-wheel drive vehicle from a wheel speed of each wheel of the four-wheel drive vehicle. In the vehicle body speed estimation device and a vehicle body speed estimation method, a controller determines whether a deviation of at least two of the wheel speeds among the wheel speeds is within a first prescribed range. The controller switches a method for selecting the wheel speed used for estimating the vehicle body speed between a first method and a second method when a sign of a drive torque that is applied to each of the wheels is reversed and the deviation of at least two of the wheel speeds among the wheel speeds is within the first prescribed range.

  • Patent number: 11933234
    Abstract: An engine is provided with a turbo charger including a wastegate valve. A first setpoint of opening of the wastegate valve is set in accordance with a target boost pressure. While a difference between the target boost pressure and a real boost pressure is large, the opening is controlled to a second setpoint, wherein the second setpoint is smaller than the first setpoint. While the opening is controlled to the second setpoint, it is determined whether a condition for limitation is satisfied in which an intake air quantity is above an intake air quantity criterion and an engine rotation speed is above an engine rotation speed criterion. When the condition is satisfied, the opening is controlled in a direction to increase from the second setpoint. The engine rotation speed criterion decreases as the intake air quantity increases. The intake air quantity criterion decreases as the engine rotation speed increases.
