Time to Line Crossing (TLC) in Computer Simulation of the Movement of a Car Equipped with the Lane Departure Avoidance System

Andrzej Reński

Abstract

The paper presents a computation model of a driver-vehicle-environment system, in which the car is equipped with the Lane Departure Avoidance system. The system avoids driver if it recognises a possibility of departure of the lane in given time period (TLC - Time to Line Crossing). The vehicle control model used in the computer simulation consists of the three elements: the vehicle (road-vehicle kinematics and vehicle dynamics), the driver (his perception and response), the environment and the impact of different disturbances. In order to describe the lane departure avoidance system the model was extended with an algorithm describing its function. The Time to Line Crossing is an important parameter used in this algorithm. In the paper the results of calculations of two manoeuvres will be presented: reaction to side wind and lane change manoeuvre. The results obtained for different parameters of the Lane Departure Avoidance system are compared with the results obtained for the model without this system. The method presented in the paper makes it possible to investigate the influence of the lane departure avoidance system on the movement the car. It is shown that from the TLC threshold value assumed in the system depends whether or how the driver can correct the trajectory of the car in a safe way.
