A kind of double-clutch automatic gearbox and power drive system dynamic test stand
Technical field
The utility model relates to a kind of double-clutch automatic gearbox and power drive system dynamic test stand, especially relates to the dynamic simulation test bed of a kind of dual-clutch transmission and electric-control system test and evaluation.
Background technology
Double-clutch automatic gearbox (Dual Clutch Transmission, DCT) can utilize its structural characteristics to realize the power failure-free of shift process and improve the power performance of vehicle, but the control of double clutch speed change is comparatively complicated, the double clutch vehicle must rely on the effective control to DCT, further the shift quality of lifting vehicle and longitudinal drive performance.
in the control of dual-clutch transmission, its core and difficult point are very, the control of the clutch coupling on the even number axle and synchronizer topworks, the how action of solenoidoperated cluthes and synchronizer topworks in shift process, guarantee that accurately the joint of two clutch couplinges and the motion of fractional dose and synchronizer are the keys that shift quality improves, in practice, the various functions of dual-clutch transmission and electric-control system adopts off-line simulation and hardware in the in addition test evaluation of the mode of ring usually, need to set up the double-clutch speed changer model during off-line simulation but there are certain difference in institute's established model and real vehicle situation, can not verify preferably the gained control strategy, and at existing hardware in ring, the most of no-load running of dual-clutch transmission topworks motor and transmission output shaft, there is not real power input yet in transmission input shaft and lacks actual clutch part, so be difficult to simulated dual clutch real vehicle ruuning situation truly, and then can not test dual-clutch transmission and electric-control system preferably.
China Patent Publication No. is that the patent of CN101140198A discloses vehicle double clutch type automatic speed transmission hardware at the loop simulation test stand frame, this scheme is set up automobile multi-state Digital Simulation mathematical model by host, be converted into the C code, receive and download in its CPU by target machine through Ethernet, then control the topworks of two clutch couplinges and synchronizer by ECU (Electrical Control Unit), and emphatically double-clutch speed changer is narrated in multi-state Digital Simulation mathematical model, but its hardware only has double clutch actuating motor and synchronizer actuating motor at loop section, do not relate to the double clutch part, motor torque and the load torque on output shaft that the more important thing is the double clutch input shaft are all by the software section the Realization of Simulation, there is very large gap with actual conditions, and then can not carry out test evaluation to dual-clutch transmission and electric-control system exactly.In addition, the double-clutch speed changer control strategy in its hardware-in-loop simulation platform in the variator ECU (Electrical Control Unit) is real-time calibration as required, lacks dirigibility.
China Patent Publication No. is that the patent of CN102841542 discloses dry dual clutch electrical control unit of automatic transmission hardware-in-loop simulation testing table.This scheme comprises synchronizer actuating motor, PC, AutoBox controller prototype, clutch coupling actuating motor, riding manipulation mechanism and clutch pack.Be that the patent of CN101140198A is the same with patent publication No., this scheme does not have the motor torque of double clutch input shaft and the real load such as load torque on output shaft equally, there is very large gap with actual conditions, and then can not carry out test evaluation to dual-clutch transmission and electric-control system exactly.
