It applies example not limit the value range of first threshold and second threshold, usually can freely be set according to specific control strategy
Fixed, under different control strategies, the value of first threshold and second threshold is all not quite similar.The first threshold is set in the controller
After value and second threshold, then controller carries out the judgement of step S1 and according to the judging result of step S1 in five kinds of driving moulds automatically
Automatically switch between formula.
The above is only the preferred embodiments of the present utility model only, is not intended to limit the utility model, all practical at this
Made any modifications, equivalent replacements, and improvements etc., should be included in the guarantor of the utility model within novel spirit and principle
Within the scope of shield.
