Résumé
While the concept of automated highway driving seems trivial at first, there are many hazards scattered throughout a constantly changing environment. Many of the proposed driving strategies however, are often limited to control well within vehicle limits. It is due to the complexity of developing robust control around these limits that fully autonomous vehicles remain a figment of the future.In the event of an imminent collision, driving at the limits of the vehicle can significantly increase the likelihood of evasion. As the tires are the only method of contact between the vehicle and the road, maximizing tire output correlates to maximizing vehicle performance. Because a tires force can be applied in any direction, there are infinitely many ways to reach a vehicle's limits. For example, one driver may choose to brake before turning to enable the vehicle to turn harder during the maneuver, while another driver may choose to brake whilst turning. With the goal of finding an optimal point of operation for the vehicle, a study was conducted to test the effectiveness of different braking strategies. To simulate an active-collision scenario, a vehicle was simulated performing a highway lane change maneuver. Across studies, braking strength and distance were varied to evaluate handling performance at different operating points around the vehicle limits.Upon analysis of the collected data, it was discovered that the addition of braking can increase the effectiveness of the maneuver when employed correctly. Additionally, it was found that the braking strength of the vehicle played a significantly larger role in the maneuver’s effectiveness than braking distance. Although results were only plotted for a few points around the vehicle’s traction circle, the results demonstrated trends which could be extrapolated to predict the vehicle’s performance at other operating points.
