  • Patent number: 11072364
    Abstract: One object is to provide a steering device that facilitates disengagement of a speed reducer so that, for example, when the speed reducer fails, the speed reducer can be disengaged to enable steering of a vehicle with a manual operational force alone. This application relates to a steering device provided with a steering mechanism and a speed reducer. The steering mechanism steers tires of a vehicle under a steering force from a steering wheel. The speed reducer is connected to a motor for outputting a steering assistance force corresponding to the steering force. The speed reducer enlarges the steering assistance force and transmits the enlarged steering assistance force to the steering mechanism. The speed reducer is connected to the steering mechanism via a speed reducer arm.

  • Patent number: 11038882
    Abstract: A remote control system includes an electrical apparatus, a terminal device, and a server device. The terminal device receives a first encrypted apparatus ID in which an apparatus ID is encrypted from the electrical apparatus. The terminal device transmits the first encrypted apparatus ID to the electrical apparatus. The electrical apparatus transmits the apparatus ID and the first encrypted apparatus ID to the server device. The terminal device transmits the first encrypted apparatus ID to the server device. The server device determines whether there is a match in the first encrypted apparatus ID received from the electrical apparatus or the terminal device. When there is a match, the server device registers the apparatus ID in a first security state.

  • Publication number: 20210140536
    Abstract: In a hydraulic control device switchable between a first state in which a first oil is supplied from a first pump to a hydraulic operation part via a bypass valve and a second state in which the first oil supplied from the first pump is pressurized by using the second pump and the pressurized first oil is supplied, as a second oil, to the hydraulic operation part, control that adds a correction hydraulic pressure of a predetermined amount to the hydraulic pressure of the oil discharged from a valve for adjusting the pressure of the oil supplied to the hydraulic operation part is performed when the second state is switched to the first state due to a stop or a low rotation state of the second pump.

  • Publication number: 20210140534
    Abstract: The disclosure provides a hydraulic control device capable of suppressing an excessive increase in the rotation speed of a second pump and stabilizing the discharge pressure of the second pump. The target rotation speed of the second pump for making a pressure value of a first oil close to an estimated value of a pressure value of a third oil is calculated, and a feedback amount with respect to the target rotation speed is calculated by subtracting the estimated value of the pressure value of the third oil from the pressure value of the first oil detected by a hydraulic sensor. Time regions for performing calculation of the feedback amount include an update region in which the feedback amount with respect to the target rotation speed is updated, and a hold region in which update of the feedback amount with respect to the target rotation speed is temporarily stopped.

  • Publication number: 20210140535
    Abstract: Provided is a hydraulic control device in which in the rotation control of the second pump, the required discharge pressure of the second pump can be more reliably maintained below a predetermined pressure in the control that keeps the target rotation speed constant after the feedback control ends. In the rotation control of the second pump, in the control which keeps the target rotation speed constant after the feedback control ends, the rotation of the second pump is controlled by adding a predetermined addition rotation speed to the target rotation speed corresponding to the required discharge pressure. Since the required discharge pressure of the second pump can be maintained below a predetermined pressure in the fixed mode by the addition rotation speed, it can reliably obtain the effect of reducing the work load of the first pump and contribute to the improvement of the fuel efficiency of the vehicle.

  • Publication number: 20210140537
    Abstract: The disclosure provides a hydraulic control device. The operating/stopping of the second pump is determined based on a value of a difference between a reduced work rate of the first pump when the second pump is operated and a power consumption of the second pump. In a state where the second pump is stopped, the power consumption of the second pump is calculated based on an estimated value of a pressure of oil supplied to the hydraulic operation part and an estimated value of a pressure of oil supplied from the first pump to another hydraulic operation part or a lubrication target operating at a lower pressure than the hydraulic operation part. In a state where the second pump is operated, the power consumption of the second pump is calculated based on an actual rotation speed and an actual torque of the second pump.
