Abstract

Provided is a vehicle display device configured to be mounted on a vehicle. The vehicle display device includes a curve detection unit, a road state categorization unit, and a display unit. The curve detection unit detects a curve that is included in a target traveling line and has a curvature. The road state categorization unit categorizes a state of the road on which the target traveling line including the curve is set, in one class out of a plurality of classes, according to possibility of presence of the curve having the curvature of a predetermined value or more. The display unit displays a representation that indicates the curvature of the curve. The curvature corresponds to the class in which the state of the road has been categorized.

Claims

1. A vehicle display device mounted on a vehicle, wherein the vehicle includes at least one first processor programmed to:

recognize environment including a road forward of the vehicle;

set a target traveling line of the vehicle based on a recognition result; and

control the vehicle to travel along the target traveling line, the vehicle display device comprising;

at least one second processor programmed to;

detect a curve in the target traveling line;

determine whether the detected curve in the target traveling line is on a first section or a second section of a high-standard road, the first section being a road devoid of a branch and a joint on the high-standard road, the second section being a road including at least the branch or the joint on the high-standard road; and

display a first symbol assigned to the determined first section or a second symbol assigned to the determined second section on a display,

wherein the first symbol assigned to the first section comprises a first curvature,

wherein the second symbol assigned to the second section comprises a second curvature, and

wherein the second curvature of the second symbol is larger than the first curvature of the first symbol.

2. The vehicle display device according to claim 1, wherein the second processor is programmed to display:

as the first symbol, a first arrow

     1) having the first curvature and a first predetermined radius of curvature and

     2) showing a direction of the curve; and

as the second symbol, a second arrow

     1) having the second curvature and a second predetermined radius of curvature and

     2) showing the direction of the curve.
