Vehicle display device
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.
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.
