Vehicle head-up display device |
摘要 |
A vehicle head-up display device includes a pattern generation unit and a combiner comprised of a free-form surface lens. The pattern generation unit forms at least one image, and the combiner magnifies and reflects the image of the pattern generation unit to provide a virtual image. The combiner has a dynamic distortion of smaller than 0.4%, and the dynamic distortion is an average value of a maximum horizontal dynamic distortion and a maximum vertical dynamic distortion. |

1. A vehicle head-up display device, comprising:
a pattern generation unit for forming at least one image; and a combiner comprised of a free-form surface lens for magnifying and reflecting the image of the pattern generation unit to provide a virtual image, wherein the combiner has a dynamic distortion of smaller than 0.4%, with the dynamic distortion being an average value of a maximum horizontal dynamic distortion and a maximum vertical dynamic distortion, and the condition 1.97≦Vh/Ch≦1.99 or 2.01≦Vh/Ch≦2.09 is satisfied, where Ch denotes a width of the combiner and Vh denotes a width of the virtual image measured in the same horizontal plane as the width of the combiner. |
