Abstract: To inhibit clutch engagement during an engine restart from affecting cooperative regenerative braking control and switching of braking in a hybrid vehicle having a P2 module onboard, a control system for the hybrid vehicle includes an engine, a motor, a K0 clutch, drive shafts, a hydraulic friction brake system, and a controller capable of performing cooperative regenerative braking control. When start of the engine is requested during the cooperative regenerative braking control, the controller performs a first process of transitioning to braking only by the frictional brake system, a second process of raising an engine revolution speed while engagement of the K0 clutch is initiated after completion of transitioning to the braking, and a third process of controlling the engine to resume operating at a timing after the engine revolution speed increases to match a motor revolution speed after the engagement of the K0 clutch is initiated.

Abstract: To provide a control device for a vehicle capable of controlling the torque of a drive source so as to appropriately balance the suppression of body vibrations and the securing of a transient response during acceleration or deceleration. This control device for a vehicle includes an accelerator position sensor that detects the accelerator opening, a torque adjustment mechanism such as a throttle valve that adjusts the torque of an engine as the drive source of the vehicle, and a powertrain control module (PCM) that controls the torque adjustment mechanism based on the accelerator opening. The PCM sets the target acceleration of the vehicle based on the accelerator opening, sets the target torsion angle of the drive shaft based on the target acceleration, sets the target torque of the engine based on the target torsion, and controls the torque adjustment mechanism based on the target torque.

Abstract: A movable main contact; a movable arc contact; a puffer cylinder including the movable main contact; a hollow rod that is arranged inside the puffer cylinder, includes the movable arc contact, and has an inner space through which an insulating gas flows; a thermal puffer chamber surrounded by the puffer cylinder and the hollow rod; an insulating cover that is provided to the hollow rod, and covers the movable arc contact; an insulating nozzle provided to the puffer cylinder; and a cylindrical flow guide extending in the axial direction are included. The flow guide is installed in the thermal puffer chamber, positioned on the outer circumference side of the hollow rod, and connected to the insulating nozzle. The space between the flow guide and the hollow rod is connected to the space between the insulating nozzle and the insulating cover, and serves as a flow path of the insulating gas.

Abstract: A gas circuit breaker includes a gas suppresser composed of a protruded portion which is formed on a horizontal surface facing an exhaust cylinder of a shaft guide and which forms a gap between itself and the exhaust cylinder and an enlarged portion which is adjacent to the protruded portion and where a gap to the exhaust cylinder is enlarged so that the shaft guide, which operates along an inner circumferential surface of the exhaust cylinder, which is provided to an inner circumferential portion of a movable side main conductor and is provided to outer circumferences of an exhaust shaft and an operation rod, and couples the operation rod with the exhaust shaft, is axially adjacent to a sliding member that slides along the exhaust cylinder with no space to the exhaust cylinder and suppresses discharge of heated and pressurized insulating gas.

Abstract: While lowering sliding resistance of an exhaust cylinder and reducing effects on a circuit breaking operation, an amount of high temperature and high pressure gas discharged into an insulating support cylinder is reduced, and both ground insulation performance and circuit breaking performance are improved.

Abstract: In order to solve the above-described problems, a gas circuit breaker of the present invention has an insulating nozzle disposed so as to cover an inner surface of a coupling member such that an end surface of the coupling member and an end surface of the insulating nozzle form one surface (the end surface of the coupling member is flush with the end surface of the insulating nozzle), in order to suppress contact between a high-temperature and high-pressure gas generated by an arc and the coupling member coupling the insulating nozzle and a driving rod.
