Abstract
First and second head up displays are installed so an angle ϕ at which a first and second center line intersect is ϕ=θ+α and a distance PD between a first and second virtual emission point, is PD=L(M−L(W−D)/(H−W))/W. The α is α=arctan(W/2L), the θ is an angle of view of first or second virtual emission point, the W is a length of an eye box in a width direction of a vehicle, the L is a distance from an eye point to a virtual image plane, the M is a distance from the eye point to a point where a virtual image cannot be seen, the D is an interval between both eyes, and the H is a length of the virtual image plane on which the virtual image is displayed, in the width direction of the vehicle.
