Background technology
Along with the development of auto-industry, research staff finds in the process of research and development motor vehicle driven by mixed power, for the oil pump control aspect of Automatic Transmission, because high-voltage motor pump start process has delay phenomenon, with system pressure can be caused in the handoff procedure of mechanical oil pump not enough, affect the performance of vehicle and the durability of change speed gear box.
Summary of the invention
Technical matters to be solved by this invention realizes a kind of hybrid electric vehicle oil pump to switch reliable, and can avoid the control method of the not foot phenomenon of system pressure in handoff procedure.
To achieve these goals, the technical solution used in the present invention is: a kind of motor vehicle driven by mixed power oil pump control method:
After step 1, vehicle launch, the demand volume of system-computed motor pump;
Step 2, according to demand flow judge whether to need starter motor oil pump, if if desired starter motor oil pump then performs step 3 and do not need starter motor oil pump, perform step 5;
Step 3, system judge whether that needs are oil-filled, if desired oil-filled, do not need oil-filled, perform step 5 if perform layout 4;
Step 4, system are oil-filled;
Step 5, to complete, export the request rotating speed of Oil pump electrical machinery.
In described step 1, the demand volume of motor pump calculates according to the variable quantity of the current demand volume of system, flow that mechanical pump provides and mechanical pump flow, described current demand volume is calculated by the vent flow of chaufeur requested torque and whole transmission system, and the flow of mechanical pump and mechanical pump flowrate variation amount are calculated by the rotating speed of mechanical pump and relative speed variation
In described step 1, the motor pump flow of demand deducts by the demand volume of current system the flow that mechanical pump provides, and compensated this value by the flowrate variation amount of mechanical pump.
In described step 2, judge that motor pump is the need of startup, if the motor pump flow of demand is greater than setting threshold values, then judge that high-voltage motor oil pump needs to start, if the motor pump flow of demand is less than setting threshold values, then judge that high-voltage motor oil pump does not need to start.
In described step 3, judgement system is the need of oil-filled, if previous cycle motor pump is in halted state and the oil pressure of current system is less than certain value, then judges that system needs oil-filled, if above-mentioned condition any one do not meet, then judge that system does not need oil-filled.
In described step 4, system is oil-filled, if oil-filled condition meets, then motor pump can run a period of time with maximum speed.
In described step 5, output motor oil pump request rotating speed, if motor pump does not need to start, then output motor oil pump request rotating speed is zero, if motor pump needs to start, then the motor pump rotating speed that exports of motor pump flow rate calculation according to demand.
The present invention is according to the flow of system and flowrate variation amount, pre-cooling high-voltage motor oil pump, and export according to the control of flowrate variation correction high-voltage motor oil pump, thus avoid system pressure not foot phenomenon in hybrid electric vehicle oil pump handoff procedure, improve the durability driving effect and change speed gear box.
Accompanying drawing explanation
Below the content that width accompanying drawing every in specification sheets of the present invention is expressed is briefly described:
Fig. 1 is high-voltage motor oil pump control method diagram of circuit.
Detailed description of the invention
Change speed gear box electronic control unit (TCU) sends rotating speed request instruction to high-voltage motor oil pump controller, at request high-voltage motor oil pump from static to operational process, due to delayed and hydraulic efficiency pressure system delayed of motor response, can cause between the actual oil pressure of system and demand oil pressure and there is certain delay, so need to improve the control algorithm of motor pump.As shown in Figure 1, high-voltage motor oil pump control method of the present invention is as follows:
In control process, first the demand volume of motor pump is calculated according to the variable quantity of the current demand volume of system, flow that mechanical pump provides and mechanical pump flow, judge whether to need to start high-voltage motor oil pump according to this demand volume, then judge that system is the need of oil-filled, finally export the request rotating speed of Oil pump electrical machinery.
Specifically, perform according to following steps:
After step 1, vehicle launch, the demand volume of system-computed motor pump; According to the motor pump flow of the variable quantity computation requirement of the current demand volume of system, flow that mechanical pump provides and mechanical pump flow, the demand volume that wherein system is current is calculated by the vent flow of chaufeur requested torque and whole transmission system, and the flow of mechanical pump and mechanical pump flowrate variation amount are calculated by the rotating speed of mechanical pump and relative speed variation.The motor pump flow of demand deducts by the demand volume of current system the flow that mechanical pump provides, and compensated this value by the flowrate variation amount of mechanical pump.
Step 2, according to demand flow judge whether to need starter motor oil pump, if if desired starter motor oil pump then performs step 3 and do not need starter motor oil pump, perform step 5; Judge that motor pump is the need of startup, if the motor pump flow of demand is greater than certain value, then judge that high-voltage motor oil pump needs to start, if the motor pump flow of demand is less than certain value, then judge that high-voltage motor oil pump does not need to start.
Step 3, system judge whether that needs are oil-filled, if desired oil-filled, do not need oil-filled, perform step 5 if perform layout 4; Judgement system is the need of oil-filled, if previous cycle motor pump is in halted state and the oil pressure of current system is less than certain value, then judges that system needs oil-filled, if above-mentioned condition any one do not meet, then judge that system does not need oil-filled.
Step 4, system are oil-filled; System is oil-filled, if oil-filled condition meets, then motor pump can run a period of time with maximum speed.
Step 5, to complete, export the request rotating speed of Oil pump electrical machinery.Output motor oil pump request rotating speed, if motor pump does not need to start, then output motor oil pump request rotating speed is zero, if motor pump needs to start, then the motor pump rotating speed that exports of motor pump flow rate calculation according to demand.
The present invention is flow according to system and flowrate variation amount, pre-cooling high-voltage motor oil pump, and exports according to the control of flowrate variation correction high-voltage motor oil pump.Actv. solves the problem existing between the actual oil pressure of system and demand oil pressure and necessarily postpone.
