  • Patent number: 11193785
    Abstract: A relationship between a relative position with respect to a section where a progressing direction changes on a route and an arrangement height is set such that the arrangement height gradually increases from zero to MaxH. Then, the arrangement height gradually decreases from MaxH to zero along the route from a point on the near side of the section where the progressing direction changes (FIGS. 3B and 3G and FIGS. 4B and 4C). When traveling in the section where the progressing direction changes, a direction mark representing the progressing direction at each point on a road surface is displayed using a heads-up display so as to overlap with a position on an upper side, by an arrangement height set based on a relative position of the point with respect to the section and a set relationship, from the point.

  • Patent number: 11181953
    Abstract: A display device has a first elastic member and a second elastic member between an outer support member and an extension portion outside an image display area of a front panel. The second elastic member is disposed at the position closest to an operation portion provided on the front panel in three directions. An elastic member pressing area is provided on a lower support plate of the outer support member. The second elastic member has a high compression ratio in the front-back direction, so the second elastic member acts as a pressure resistive portion. When the front panel is pressed with a finger in the operation portion, the strain of the front panel can be suppressed to a minimum due to a pressure resistive force.

  • Patent number: 11137852
    Abstract: A pressing operation detection device includes a pressing operation determination unit determining whether a pressing operation has been performed based on a touch on an operation unit and a pressing amount, an increase-and-decrease frequency detection unit detecting occurrence frequency of increase and decrease of a pressing amount every predetermined period of time, and a determination controller changing content of the determination process of the pressing operation determination unit based on the occurrence frequency detected while a touch on the operation unit is not detected. When a pressing amount is detected although the operation unit is not touched, assuming that increase and decrease of the pressing amount is caused by vibration, content of the determination process is changed such that influence of the vibration is reduced so that detection of a pressing operation which brings a feeling of strangeness to the user which is caused by the vibration may be avoided.

  • Patent number: 11127389
    Abstract: An active noise control unit generates a noise canceling sound of a single frequency that cancels engine sound heard by an occupant and outputs the noise canceling sound to a speaker through an amplifier. A second harmonic detector and a third harmonic detector detect a magnitude of a harmonic component of the noise canceling sound included in sound collected by a microphone. A controller controls a frequency of the noise canceling sound generated by the active noise control unit to a fundamental frequency of the engine sound based on a rotation frequency of the engine, and in addition, causes an output level control unit to control a level of the noise canceling sound to be output to the amplifier so that the level of the noise canceling sound becomes higher when the magnitude of the harmonic component exceeds a predetermined threshold value.
