Various driver assistance systems have been developed to help avoid obstacles in front of vehicles. Some systems, called Evasive Steering Assist(ESA), utilize chassis control systems to improve the vehicle’s steering response to avoid collision. However, rapid evasive steering makes the vehicle unstable and causes secondary accidents. Therefore, the Evasive Steering Assist system needs to sense the vehicle\'s stability and perform appropriate control to prevent the vehicle from becoming unstable. In this study, we propose an Evasive Steering Assist system based on vehicle lateral slip estimation. The proposed system controls the Electronically Controlled Suspension(ECS) of the vehicle based on environmental sensors and estimated slip information to improve cornering performance and lateral stability. The system’s performance is verified through experiments with a test vehicle equipped with ECS in various scenarios, including emergency lane changes. |
