Display control device and display system
A display control device includes a surrounding information acquisition unit that acquires surrounding information around a host vehicle, a preceding vehicle information acquisition unit that acquires, based on the surrounding information, preceding vehicle information on a preceding vehicle that travels in front of a driving lane of the host vehicle, an effect calculation unit that calculates, based on the preceding vehicle information, effect information on a slipstream of the preceding vehicle, and a display control unit that performs control, based on the effect information, to display the effect of the slipstream of the preceding vehicle from a preceding vehicle display unit that displays the preceding vehicle to a host vehicle display unit that displays the host vehicle.
1 . A display control device comprising:
a processor programmed to:
acquire surrounding information around a host vehicle;
acquire, based on the surrounding information, preceding vehicle information on a preceding vehicle that travels in front of the host vehicle in a driving lane;
calculate, based on the preceding vehicle information, effect information on a slipstream of the preceding vehicle; and
perform control, based on the effect information, to display an effect of the slipstream of the preceding vehicle in an animation that moves from a preceding vehicle display unit that displays the preceding vehicle toward a host vehicle display unit that displays the host vehicle,
wherein the processor is programmed to perform control to:
display a moving speed of the animation faster as the effect of the slipstream becomes larger, and
display a shape of a mark in the animation to be either (i) a straight line of which a number increases as an effect of slip stream increases or (ii) a straight line of which a length increases as an effect of slip stream increases.
2 . The display control device according to claim 1 , wherein the processor is programmed to perform-performs control to display the animation in a larger size as the effect of the slipstream becomes larger.
3 . A display system comprising:
the display control device according to claim 1 ; and
a display unit that is provided in front of a driver's seat in a vehicle cabin and that displays an image controlled by the display control device.
4 . The display control device according to claim 1 , wherein the processor is programmed to perform control to display the shape of the mark in the animation to be the straight line of which the number increases as the effect of slip stream increases.
5 . The display control device according to claim 1 , wherein the processor is programmed to perform control to display the shape of the mark in the animation to be the straight line of which the length increases as the effect of slip stream increases.
