A New Lane Departure Warning Algorithm Considering the Driver’s Behavior Characteristics

الملخص EN

In order to meet the driving safety warning required for different driver types and situations, a new lane departure warning (LDW) algorithm was proposed.

Its adaptability is much better through setting the different thresholds of time to lane crossing (TLC) using fuzzy control method for driver with different driving behaviors in different lanes and different vehicle movements.

To ensure the accuracy of computation of TLC under the different actual driving scenarios, the algorithm was established based on vehicle kinematics and advanced mathematics compared to other ways of computation of TLC.

On this basis, a LDW strategy determining driver's intentions was presented by introducing identifying vehicle movements.

Finally, a vast quantity of the real vehicle experiments was given to demonstrate the effectiveness of the proposed LDW algorithm.

The results of the tests show that the algorithm can decrease false alarm rate effectively because of distinguishing from unconscious by real-time vehicle movements, and promote the adaptability to the driver behavior characteristics, so it has favorable driver acceptance and strong intelligence.
