  • Publication number: 20230103046
    Abstract: Provided is a vehicle equipped with a steer-by-wire type steering device and designed to ensure that a wheel-turning actuator is activated before the vehicle starts traveling, thereby improving the reliability of steering while the vehicle is traveling. A vehicle 1 includes: a steering member 15 for receiving steering operations; a wheel-turning actuator 19 mechanically separated from the steering member 15 and configured to turn wheels; a state switching device 6 for switching between a fixed state in which the vehicle is fixed at a current position and a release state in which the vehicle is released from being fixed at the current position; and a control device 9 for controlling the wheel-turning actuator 19 and the state switching device 6, wherein the control device permits the state switching device to switch from the fixed state to the release state only on or after completion of activation of the wheel-turning actuator.

  • Patent number: 9399484
    Abstract: A vehicle steering system that hardly gives a driver a feeling of strangeness even in mode switching is provided. Even if condition such as a defect of a system, which caused switching from SBW mode to EPS mode, has been resolved, a mode switching section waits for a timing of switching from EPS mode to SBW mode until a second condition is satisfied. The second condition is that the vehicle is in a certain state in which the driver hardly notices mode switching. The mode switching section waits for and judges a timing when the vehicle becomes into a certain state in which the driver hardly notices mode switching, and then performs switching from EPS mode to SBW mode.

  • Patent number: 9205865
    Abstract: A vehicle steering device includes a control unit that determines a turning angle of wheels in accordance with a steering angle of a steering wheel provided in a vehicle and mechanically separated from the wheels. The control unit determines whether or not a previous vehicle speed is higher than a predetermined speed when a state of a start switch that starts a driving unit of the vehicle is switched from an ON state to an OFF state. If the previous vehicle speed is higher, the control unit continuously turns ON a power supply of the vehicle steering device regardless of a current vehicle speed until a predetermined time elapses, and turns OFF the power supply of the vehicle steering device after the predetermined time elapses. If the previous vehicle speed is not higher, the control unit turns OFF the power supply of the vehicle steering device.

  • Patent number: 8462957
    Abstract: A hearing aid (101) comprises a microphone (121) converting sound into an electrical signal, a processor (105) disposed inside a main body case (102), a first volume adjuster (104) having a variable resistor, and a receiver (123) converting an electrical signal into sound. The processor (105) has an amplifier (135) amplifying an electrical signal from the microphone (121), a second volume adjuster (105b) setting a degree of amplification by the amplifier (135), and a controller (130) controlling the second volume adjuster (105b) and the amplifier (135). The controller (130) detects the resistance value of the variable resistor, determines whether or not the resistance value has exceeded a specific threshold, acquires a specific value for the degree of amplification by the amplifier (135), and sets the degree of amplification by the amplifier (135) to this specific value when the controller determines that the resistance value has exceeded the specific threshold.

  • Patent number: 8396283
    Abstract: A three-dimensional-object can be effectively detected. A pair of image capture devices capture a three-dimensional-object and calculate disparity component data of subdivided-image regions, respectively. On a basis of the disparity component data, gray scale values indicative of distances from the image capture device are calculated and a gray scale image in which each region has its corresponding gray scale value is generated. A model of the three-dimensional-object is defined and correlation values is calculated to show the degree of a similarity between the model and the image subdivided regions in the gray scale image. The model is a two-dimensional image with a shaping characteristic when the three-dimensional object is viewed from positions of the image capture devices while each subdivided region of the two-dimensional image has a gray scale value indicative of a distance from the image capture device at a portion corresponding to the three-dimensional object.
