  • Patent number: 10690067
    Abstract: When a waste gate valve (7) is forcibly fully closed for learning control at the time of start, the drive force of an electric actuator (20) is initially set to a large first level, and when a predetermined position (L1) immediately before seating is reached, the driving force is reduced to a second level. As a result, a valve body (7a) is gently seated. When a predetermined time (TM1) passes, the driving force is increased to a third level. Consequently, the electric actuator (20) presses the valve body (7a) onto a seat surface (34a) while displacing a spring member (37). As a result, a reliable sealability is obtained.

  • Patent number: 10683797
    Abstract: A waste gate valve (7) of a turbocharger (3) is fully opened during idling after warm-up is completed in order to reduce exhaust resistance. However, during idling in an engine cold state when a cooling water temperature (TW) is below a threshold value (TW1), the waste gate valve (7) is open-loop controlled to an intermediate opening degree that is smaller than full opening. An ignition timing is delayed (retarded) for catalyst warm-up. When the cooling water temperature (TW) reaches (t3) the threshold value (TW1), the opening degree of the waste gate valve (7) is set to full opening. When an accelerator opening degree (APO) becomes large (t4) before warm-up is completed, the limitation of the opening degree is released.

    Abstract: The present invention provides a vehicle control method capable of suppressing an increase in the frequency of stopping and restarting of the engine when the braking device is activated at the self-driving mode. When the operation mode is set as self-driving, the braking device is activated in accordance with a system deceleration request to keep an actual vehicle-speed at a target vehicle-speed or change the actual vehicle-speed at the target vehicle-speed or lower depending on environment surrounding the vehicle. Further, a braking amount is estimated, the braking amount is a magnitude of a braking force generated from the activated braking device. When the braking amount is an engine-stopping enabling threshold or more, enabling stopping is allowed. When the braking amount is less than the engine-stopping enabling threshold, enabling stopping is not allowed.

  • Patent number: 10668596
    Abstract: A surface treatment device includes a vacuum blast head, an air curtain-forming unit and an auxiliary air injection unit. The vacuum blast head includes an injection nozzle and a suction hole. The injection nozzle injects a polishing agent used for blast treatment on a surface of a material to be treated. The suction hole sucks up the injected polishing agent with suction air. The air curtain-forming unit injects air toward the surface of the material to be treated to form an air curtain that surrounds the injected polishing agent. The auxiliary air injection unit injects auxiliary air between the air curtain and the suction air toward the material to be treated at a lower pressure than the air that forms the air curtain.

    Abstract: According to a control method for a hybrid vehicle that is caused to run by a drive motor as a load being supplied with electric power of a battery and electric power generated by an electric generator, a total distance to empty is calculated on the basis of a shortage of a generating power output of the electric generator with respect to a required running power output and an amount of charge remaining in the battery. Specifically, a length of time for which the shortage of the generating power output of the electric generator with respect to the required running power output is covered by the amount of charge remaining in the battery is calculated, and a distance that the hybrid vehicle can run for this length of time is set as a total distance to empty.

    Abstract: The electric vehicle control method is a control method that includes the motor that gives braking force or driving force to a vehicle in accordance with an accelerator operation, by which the braking force is controlled when an accelerator operation amount is smaller than a given value and the driving force is controlled when the accelerator operation amount is the given value or larger. The electric vehicle control device estimates disturbance torque that acts on the motor as resistance component relating to a gradient and executes correction by which the braking force or the driving force is increased or decreased so as to cancel the resistance component in accordance with a disturbance torque estimated value Td. Then, on a downhill road at a given gradient or more, a correction amount of the braking force or the driving force is reduced.
