  • Patent number: 10351165
    Abstract: A steer by wire steering system for a vehicle includes a reaction force actuator 25, a steering actuator 28, a control unit 40, and a clutch 20, 120 that can selectively connect a steering wheel 11 with road wheels 3 to be steered. The control unit is configured to operate in an emergency mode when a failure is detected while the control unit is operating in a steer by wire mode. The emergency mode includes commanding the clutch to engage, terminating the steer by wire mode, performing a position keep control whereby the steering actuator is driven so as to maintain a fixed steering angle of the road wheels, initiating a power assist mode using the reaction force actuator, and once the clutch is fully engaged, terminating the position keep control.

  • 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.
