Abstract
A vehicular control system includes a plurality of cameras that capture image data, at least one radar sensor that senses radar data and a control that processes image data captured by the cameras and sensed radar data. The control, responsive to processing of captured image data, detects lane markers and/or road edges and determines curvature of the road being traveled by the equipped vehicle. The control processes captured image data and sensed radar data to detect vehicles. The control, based on processing of captured image data and/or sensed radar data, detects another vehicle and determines distance from the equipped vehicle to the detected other vehicle. The control may, based at least in part on the detection of another vehicle and the determination of distance from the equipped vehicle to the detected other vehicle, determine whether it is safe for the equipped vehicle to execute a lane change maneuver.
