  • Publication number: 20190143891
    Abstract: An alert may not be generated at railroad crossings. An alert control apparatus (300) includes data obtaining units (41 to 43) that obtain sensing data (a to j) from sensors (6 to 15), a railroad crossing recognizer (44) that recognizes the position of a railroad crossing relative to a vehicle based on the sensing data, and a criterion changer (46) that changes, based on the recognition result, a determination criterion used by a distracted driving alert device (200) to generate an alert to distracted driving to a criterion with which the alert is more likely to be generated while the vehicle is passing the railroad crossing than at other times.

  • Publication number: 20190147274
    Abstract: Accurate driver state determination achieving safety is enabled without being affected by differences between individual drivers. A driver state determination apparatus for determining a driver state, such as distracted driving, includes a calculator that determines a direction of a vehicle driver's face or gaze based on first sensing data output from a first sensor and including an image of the driver, and calculates statistical information about a direction in which the driver looking straight ahead retains his or her gaze with respect to a forward direction of a vehicle. A correction unit corrects the determined face or gaze direction of the driver with respect to a reference direction defined as the forward direction of the vehicle based on the statistical information. A determiner determines a driver state based on a deviation of the corrected face or gaze direction of the driver from the reference direction.

  • Publication number: 20190147272
    Abstract: A driver performing a lane check by looking back for safe driving can be alerted based on the driver's gaze deviating from a view area for usual driving. A distracted driving determination apparatus, a distracted driving determination method, and a program for distracted driving determination recorded on a recording medium compare a change pattern detected from changes in the gaze or face orientation of the driver with a predetermined reference pattern, and change a usual determination condition for detecting distracted driving to a temporary determination condition when the change pattern matches the reference pattern. This prevents the line check from being determined to be distracted driving.

  • Publication number: 20190084426
    Abstract: This motor driving control apparatus has (A) an inverter unit configured to drive a motor; (B) a separation switch configured to separate a power source from the inverter unit; and (C) a controller configured to instruct the separation switch to separate the power source from the inverter unit and control the inverter unit to perform switching according to a speed and a braking target torque, upon detecting an event that braking should be performed without passing a regenerative current to the power source from the inverter unit. By introducing the separation switch that operates as described above, it becomes possible to perform control so as to consume the power by the motor itself without passing the regenerative current to the power source such as a battery.

  • Patent number: 10014568
    Abstract: Embodiments described herein relate a mobile communication device and techniques to suppress deterioration of antenna characteristics. The mobile device includes metallic members that are disposed around, or in portions of a casing of the mobile device. The metallic member is grounded directly to a ground plane of the mobile device at a first predetermined position. The grounded metallic member forms a stub line that cancels a flow of electric current though the metallic member. Furthermore, the metallic member is also connected to the ground plane, at a second predetermined location, via a resonant circuit. The mobile device is capable of adjusting a phase of the antenna current flowing through the device, when the mobile device is being operated by a user, and thus suppresses deterioration of antenna characteristics in certain desired frequency bands.
