  • Patent number: 12266943
    Abstract: A processing unit of a command generation device which is provided separately from a general-purpose inverter, performs following processing. A rotation calculation unit calculates a value relating to a rotation of a rotor of a virtual power generator when the virtual power generator is driven according to an active power command based on a rotor model that simulates a driving of the virtual power generator and calculates a value relating to the rotation of the rotor of the virtual power generator and an active power command. A target determination unit determines a target value of a voltage frequency and a target value of an active power based on the calculated value relating to the rotation. A command generation unit generates a control command for the inverter based on the determined target value of the voltage frequency and the target value of the active power.

  • Patent number: 12240439
    Abstract: A hybrid electric vehicle includes an engine, a motor, a clutch provided between the engine and the motor, a battery for charging regenerative electric power of the motor, and a control device that controls the engine, the motor, and the clutch. The control device includes a charge determination unit that determines whether the battery is chargeable when there is a deceleration request, and a deceleration control unit that executes, in a negative determination, a first deceleration process to decelerate the hybrid electric vehicle by friction torque of the engine, and executes, in a positive determination, a second deceleration process to decelerate the hybrid electric vehicle by regenerative torque of the motor. In the second deceleration process, the deceleration control unit causes the motor to output the friction torque at a rotational speed of the engine corresponding to a rotational speed of the motor as the regenerative torque.

  • Patent number: 12202412
    Abstract: A support structure for supporting a flat inverter located between seats aligned along the vehicle width direction is provided. A bracket supports the inverter in a horizontal position above a floor tunnel of a floor between the seats in a passenger compartment such that it is spaced apart from the floor tunnel. The bracket has a pair of rear leg portions aligned along the vehicle width direction. Middle parts of the pair of rear leg portions are formed so as to be easily bent outward or inward in the vehicle width direction. When a load is applied to the bracket due to movement of the seats during a side impact on the vehicle, the pair of rear leg portions bend, and the horizontal position of the inverter is disrupted.

  • Publication number: 20250018559
    Abstract: A body can be configured to be selectively morphable. One or more body support members can be operatively connected to an outer surface of the body. The one or more body support members can be arranged in a pattern to define at least one morphing region. A contracting member (e.g., a shape memory polymer) can be operatively connected to the outer surface of the body. When activated, the contracting member can contract, which can cause the body to morph (e.g., bend) from a non-activated configuration into an activated configuration.
