Vehicle display device, display method, and storage medium

A computer readable non-transitory storage medium storing a program executable by a processor to display a predetermined image at a display region depicting a scene ahead of a vehicle by executing processing comprising:

• identifying a traffic lane ahead of the vehicle;
• identifying a current position of the vehicle with respect to the traffic lane;
• establishing a planned position that is a planned lane change destination based on the current position of the vehicle;
• and
• when the vehicle is to change lanes, displaying a direction image indicating a direction of progress of the vehicle at the display region, and altering a direction indicated by the direction image based on a relative positional relationship of the vehicle with respect to the planned position wherein an angle of the direction image corresponds with a rotation of a steering wheel;
• wherein:
• the direction image includes a plurality of images arranged in a row from a near side toward a far side of the display region and indicating each direction corresponding to each rotation angle of the steering wheel along a planned travel route;
• and
• displaying the direction image further comprises displaying the plurality of images arranged in a straight line toward a direction of the lane change destination at a time at a start of the lane change, and then, continually alter the arrangement to a curved arrangement over time in coordination with a rotation of the steering wheel.

A vehicle display device configured to display a predetermined image at a display region depicting a scene ahead of a vehicle, the vehicle display device comprising:

• a memory;
• and
• a processor coupled to the memory, the processor being configured to:
• identify a traffic lane ahead of the vehicle,
• identify a current position of the vehicle with respect to the traffic lane,
• establish a planned position that is a planned lane change destination based on the current position of the vehicle, and
• when the vehicle is to change lanes, display a direction image indicating a direction of progress of the vehicle at the display region, and alter a direction indicated by the direction image based on a relative positional relationship of the vehicle with respect to the planned position wherein an angle of the direction image corresponds with a rotation angle of a steering wheel;
• wherein:
• the direction image includes a plurality of images arranged in a row from a near side toward a far side of the display region and indicating each direction corresponding to each rotation angle of the steering wheel along a planned travel route;
• and
• wherein the processor is further configured to display the plurality of images arranged in a straight line toward a direction of the lane change destination at a time at a start of the lane change, and then, to continually alter the arrangement to a curved arrangement over time in coordination with a rotation of the steering wheel.
