PICOS18 is a real-time, multi-task control system kernel based on OSEK/VDX protocols. An embedded controller for semi-active suspension is designed in order to improve the response rate and realize the modularization design of the control system. The structure of embedded system is designed based on PICOS18. The whole control system is divided into 9 tasks according to the data flow method, and the priority of each task is defined properly to achieve the requirement of real-time performance. Through ldquohard-ware in linerdquo simulation, it is proved that the controller based on PICOS18 can improve ride comfort ability and road holding ability at the same time.
