| Abstract: | A low level drive system (LDS) of continuously variable transmission (CVT) which is used to drive stepper motor and high speed digital on off valves is developed.The low level drive principle and electronic elements used in the system are given.Drive circuits and controller area network (CAN) protocol between gearbox interface unit (GIU) and engine management system are given.Hardware in the loop simulation is operated,finally stepper motor and high speed digital on off valves succeed to be driven.Ratio control,clamping force control and clutch control are achieved rapidly and accurately,and the low level drive system is validated. |
