  • Publication number: 20210269031
    Abstract: Based on information acquired by an external sensor and an internal sensor, which acquire information about a periphery of a host vehicle and host vehicle information, determining as to whether or not the host vehicle has stopped with the right/left-turn travel being intended. When a right/left turn stop determination is made for the host vehicle, determining as to whether or not there is an oncoming vehicle in an intended travel trajectory of the host vehicle. When the oncoming vehicle is determined to not be present in the intended travel trajectory, determining as to whether or not a far-side oncoming vehicle present on a far side of the intended travel trajectory has stopped. When the far-side oncoming vehicle is determined to have stopped, the right/left-turn travel is allowed.

  • Publication number: 20210217304
    Abstract: A driving plan display method controls an in-vehicle road surface image display device that can display an image on a road surface is controlled using a display controller to display driving plan-related information of a host vehicle on the road surface. In the method, the driving plan-related information of the host vehicle and information relating to prediction of a pedestrian's crossing is acquired. Based on the acquired information, a predicted crossing point is obtained at which the pedestrian's crossing is predicted on a planned travel route of the host vehicle. Then, an image of the driving plan-related information of the host vehicle from a current position of the host vehicle to the crosswalk as the predicted crossing point is displayed on the road surface of the crosswalk as the predicted crossing point with the road surface image display device.

  • Patent number: 10953896
    Abstract: In lane selection control in which a lane in which a host vehicle travels is selected based on the map information and information acquired by an external sensor that acquires periphery information of the host vehicle, a self-position correction object in an intended travel route is identified based on the map information. When the host vehicle reaches a correction point where the self-position correction object is present, a determination is made as to whether or not the self-position correction object can be recognized by the external sensor from the lane in which the host vehicle travels. Upon determined that the self-position correction object cannot be recognized from the center lane in which the host vehicle travels, a lane change to a leftmost lane where the self-position correction object can be recognized is made before the host vehicle reaches the correction point.

  • Patent number: 9318955
    Abstract: A power supply apparatus supplies a power supply signal to a device's power supply terminal via a power supply line. An A/D converter receives, via a feedback line, an analog measurement value corresponding to the power supply signal supplied to the device's power supply line, and converts the analog measurement value into a digital measurement value. A digital calculation unit generates a control value by digital calculation such that the digital measurement value from the A/D converter matches a predetermined reference value. A D/A converter digital/analog converts the control value so as to supply the analog power supply signal to the device's power supply terminal via the power supply line. A feedback ratio calculation unit calculates the ratio between the control value and the digital measurement value. The digital calculation unit is configured to change its calculation content based on the ratio calculated by the feedback ratio calculation unit.
