Abstract:

An integrated control research on SASS and ABS  adopting layered coordinated control was carried out.Controllers were designed separately with bottom and upper coordinated controllers.The bottom controllers including SASS and ABS were 2 separate controllers,which were used to carry out different control tasks of subsystems.The upper coordinated controller was used to make the necessary adjustments and amendments of bottom controllers,aiming to improve whole vehicle synthesis performance.The experimental results show that layered coordinated control can coordinate contradiction between SASS and ABS,improve the stabilization and security of vehicle in emergency braking,enhance the overall performance of the vehicle.
