Abstract
An information calculation device includes an ECU configured to specify right and left lane marker candidate points based on edge points in the captured image, and configured to, when two edge points satisfying separation conditions are included in each of the right and left lane marker candidate points, calculates a lateral position of the vehicle, a pitch angle, a yaw angle, a lane width of a traveling lane, a curvature, and a curvature change rate by Kalman filter processing. The ECU is configured to calculate the pitch angle to be zero and the lane width to be a predetermined value when the two edge points satisfying the separation conditions are included in one of the right and left lane marker candidate points and no edge point is included in the other lane marker candidate points.
