Abstract

Various aspects of a system and method to provide driving assistance to safely overtake a vehicle are disclosed herein. In accordance with an embodiment, an electronic control unit used in a first vehicle is configured to detect a second vehicle in front of the first vehicle. A first position associated with the first vehicle and a second position associated with the detected second vehicle is determined for a first time instance. It may be determined whether a lateral distance between the determined first position and the determined second position is below a pre-defined threshold distance. A first alert is generated when the determined lateral distance is below the pre-defined threshold distance.
