Abstract
An easy-to-use vehicular active drive assist system is provided, which can continue to give a warning against the presence of a possibility of deviation of own vehicle from a traffic lane to such an extent that a driver would not find the warning noisy or annoying. A control unit makes a judgment on the possibility of deviation from a traffic lane based on the location of lane marker lines detected from a pair of camera images and the location of own vehicle, and generates a warning if the own vehicle is supposed to deviate from to the left or right of the traffic lane. This warning is produced at preset time intervals. When the direction of potential lane deviation has changed (from right to left or from left to right), a lane deviation warning of the current side of lane deviation is started immediately.
