VEHICULAR DRIVING ASSIST SYSTEM USING FORWARD-VIEWING CAMERA

A vehicular driving assist system includes a forward-viewing camera and a side object detection system disposed at a vehicle equipped with the vehicular driving assist system. The side object detection system includes a driver side-sensing radar sensor and a passenger side-sensing radar sensor. Image data captured by the forward-viewing camera is processed to detect traffic lane markers for a lane departure warning system of the equipped vehicle. Responsive at least in part to one of the radar sensors detecting a vehicle travelling in the same direction as the equipped vehicle and approaching from rearward of the equipped vehicle in a traffic lane that is to the respective side of the traffic lane that the equipped vehicle is travelling in, the vehicular driving assist system alerts a driver of the equipped vehicle of presence of the detected vehicle regardless of turn signal usage by the driver of the equipped vehicle.
