An apparatus and a method for driving control of a vehicle include a sensor including a laser sensor disposed in front of the vehicle A controller is configured to calculate a defile width in front of the vehicle based on an angle between a reference segment and an inference segment by recognizing sensing data passing through a reference point at which a virtual standard segment is in contact with the inference segment and a reference segment after confirming a position of an obstacle positioning in front of the vehicle using the sensing data received from the sensor. The controller generates the virtual standard segment for the obstacle based on the confirmed position and generates the inference segment which is perpendicular to the virtual standard segment. An output outputs a driving guide to the calculated defile under control of the controller.
