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.

4. The driving assistance system according to claim 1, wherein said one or more circuits are configured to determine whether a relative speed between said first vehicle and said detected second vehicle at said first time instance is above a pre-defined threshold speed.

5. The driving assistance system according to claim 4, wherein said one or more circuits are configured to dynamically update said first pre-defined threshold distance based on said determined relative speed and/or a geo-location of said first vehicle.

6. The driving assistance system according to claim 4, wherein said one or more circuits are configured to generate said first alert when said determined relative speed is above said pre-defined threshold speed.

7. The driving assistance system according to claim 4, wherein said one or more circuits are configured to determine said first position along a first predictive path associated with said first vehicle and a second position along a second predictive path associated with said detected second vehicle.

8. The driving assistance system according to claim 7, wherein said one or more circuits are configured to:

receive first sensor data corresponding to said first vehicle for said determination of said first predictive path, and

receive second sensor data corresponding to said detected second vehicle for said determination of said second predictive path.

9. The driving assistance system according to claim 8, wherein said received first sensor data comprises one or more of:

a steering angle, a yaw rate, and/or speed of said first vehicle and said second sensor data comprises one or more of;

a relative displacement, said relative speed, and/or a detected angle between said first vehicle and said detected second vehicle, wherein said first sensor data is received from a sensing system used in said first vehicle, and wherein said second sensor data is received from a communication device associated with said second vehicle or an object detection device of said sensing system.

10. The driving assistance system according to claim 7, wherein said one or more circuits are configured to generate said first alert indicating that said first vehicle cannot safely pass said detected second vehicle along said first predictive path when said determined lateral distance is below said first pre-defined threshold distance or said determined relative speed is above said pre-defined threshold speed.
