Design Of Electrical Park Brake Control System

Traditional mechanical parking brake technology is now mature enough.With the development of the Vehicle parking brake technology,Electrical Park Brake,which is short for EPB,has developed quickly as a new electronic control parking system.EPB has used widely aboard,but the development in domestic is still not enough.Choose Passat as a study subject to research EPB,focus on the research of both hardware and software of EPB.There is a very strict standard in cars industry,in this thesis,all designs of the circuit and the chosen of devices are based on the standard.Hardware circuit includes input&output circuit,power control circuit,CAN communication circuit,motor driver module,accelerator and gyro monitoring vehicle state module,ect.PCB should solve the difficulties of the cooling of high power devices and the ability of anti-blooming,and so on.The software department is focus on the emergency braking and conventional parking braking,conventional autohold,the move of autohold and parking braking and slope brake,ect.Besides,users could choose the proper function according to their demand.In order to design the control system,we build a platform,and we could record the experiment results through an interactive interface which is based on the platform.During the system design,by analysis the electronic parking brake control system,to study the feasibility,use the proper components to design the controller system.During the process of stabilized and development,record all datas and after repeated test,the design of a whole electronic parking brake system was finished.
