Please refer to Fig. 4 and Fig. 5, the concrete steps of the automatic gear shifting dynamic assembly system control method of the pure electric automobile of the embodiment of the invention are as follows:
Step 501: power assembly controller 4 obtains the target torque of drive motor 2, the target gear of change-speed box 3, and judge whether the needs gearshift according to the shifting commands zone bit of target gear, when the shifting commands zone bit is 1, execution in step 502, when the shifting commands zone bit is 0, execution in step 513.
Entire car controller 1 calculates the target torque of drive motor 2 and the target gear of change-speed box according to current car status information and pedal signal, and target gear and current shift compared, judge that the shifting commands zone bit is set to 0 when not needing to shift gears; Judge that the shifting commands zone bit is set to 1 when needing gearshift.Entire car controller 1 sends to the target torque of drive motor 2, the target gear of change-speed box 3 on the CAN bus 6, power assembly controller 4 obtains the target torque of drive motor 2, the target gear of change-speed box 3 from CAN bus 6, and judge according to the shifting commands zone bit, when the shifting commands zone bit is 1, change step 502 over to; When the shifting commands zone bit is 0, execution in step 513.
Step 502: power assembly controller 4 control drive motor 2 begin unloading according to certain speed, and target torque is no-load torque.
Step 503: the Digital Signals unit 41 in the power assembly controller 4 is by the torque of the drive motor output of torque observer feedback, judge whether it reaches light condition, if reach light condition then execution in step 504, if do not reach light condition then get back to step 502, continue to carry out circulation.
Step 504: power assembly controller 4 control gearshifts 5, gearshift servomotor 51 rotate and drive selector forks by reduction gear apparatus 52 and move, and make change-speed box 3 current shift gears withdraw from engagement, pluck the gear operation.
Step 505: power assembly controller 4 receives the reduction gear apparatus position of stroke sensor feedback, and when reaching neutral gear position, execution in step 506 if do not reach neutral gear position then get back to step 504, continues to carry out circulation.
Step 506: it is the speed closed loop pattern that power assembly controller 4 is regulated drive motor 2 operational modes, and the rotating speed of target that calculates drive motor 2 according to axle tach signal and target gear when Front Derailleur 3 output, the output of control drive motor 2 rotating speeds is carried out speed governing to drive motor 2.
Step 507: power assembly controller 4 receives motor speed sensor and detects the drive motor tachometer value, calculate the speed discrepancy of drive motor rotating speed and gear to be joined, when speed discrepancy is less than or equal to default threshold value, execution in step 508 is if speed discrepancy is still greater than default threshold value then get back to step 506 and continue to carry out circulation.
Step 508: power assembly controller 4 control gearshifts 5 drive selector fork and move, and make the engagement of change-speed box target gear gear mesh, the operation of putting into gear.
Step 509: power assembly controller 4 receives the reduction gear apparatus position of stroke sensor feedback, and after confirming that the target gear mesh meshes fully, execution in step 510 continues to carry out circulation otherwise get back to step 508.
Step 510: power assembly controller 4 is regulated drive motor 2 operational modes and is back to the torque closed loop mode, drive motor 2 begins to load according to certain speed, and new target torque is for obtaining the target torque of drive motor and the product of transmission ratio ratio (former transmitting ratio/target transmitting ratio) in step 501.
Step 511: power assembly controller 4 judges whether the torque value of drive motor 2 outputs of torque observer feedback reaches target torque value, and if so, then loading procedure is finished, execution in step 512, otherwise be back to step 510, continue to carry out circulation.
Step 512: power assembly controller 4 is to entire car controller 1 feedback gearshift end mark position.
Step 513: power assembly controller 4 is according to the current drive motor target torque on the CAN bus, and the power of control drive motor 2 is exported.
The embodiment of the invention has adopted the mode of integrated control, and soon the control integration of the control of drive motor 2 and change-speed box 3 gears is in power assembly controller 4.When change-speed box 3 operates in a certain gear, i.e. non-gearshift is constantly the time, and the function of power assembly controller 4 is traditional drive motor controller, the torque output of the target torque control drive motor 2 that sends according to entire car controller 1.When entire car controller 1 judgement needs gearshift, the target gear that power assembly controller 4 sends according to entire car controller 1 is coordinated the gearshift behavior of drive motor 2 and change-speed box 3, control drive motor 2 operate in respectively torque or speed closed loop state, realize simultaneously gearshift 5 pluck the gear and the operation of putting into gear.By with the control integration of dynamic assembly in power assembly controller 4, system cost and volume have not only been saved, and can be more strictly according to the motion of gearshift timing coordination drive motor and change-speed box, saved communication latency, reduce gearshift and impacted, improved dynamic property and the shifting comfort of system.
