A kind of hybrid electric vehicle cooling system control method
Technical field
The present invention relates to new forms of energy car technical field, particularly a kind of hybrid electric vehicle cooling system control method.
Background technology
Hybrid vehicle automobile cooling system, is a kind of for preventing electromotor, motor and their controller mistake Although the system petrol engine of heat has been carried out improving in a large number, but during converting chemical energy into mechanical energy, vapour The efficiency of oil turbine is the highest.Most of energy (about 70%) in gasoline is converted into heat, and distributes these heats It it is then the task of automobile cooling system.It is true that an automobile travelled on a highway, the heat that its cooling system is scattered and disappeared Amount be enough to for two general house heatings！The groundwork of cooling system is to distribute heat in air to prevent electromotor mistake Heat, but cooling system also has other important function.Electromotor in automobile operation conditions under the suitable condition of high temperature is best.As What really electromotor became is overheated, will accelerate the abrasion of assembly, so that engine efficiency reduces and gives off more multi-pollutant.
Summary of the invention
For solving above-mentioned technical problem, the invention provides a kind of hybrid electric vehicle cooling system control method, its bag Include following steps:
S1:igbt temperature sensor, through the first acquisition and conditioning circuit 1 acquisition module of sending into microprocessor, gathers mould Block continuous sampling n times also will be converted into actual igbt temperature value inv_temp after digital quantity AD medium filtering；
S2: motor temperature sensor, through the second acquisition and conditioning circuit 2 acquisition module of sending into microprocessor, gathers mould Block continuous sampling n times are also converted into real electrical machinery temperature value motor_temp by after digital quantity AD medium filtering；
S3: engine temperature sensing unit, through the 3rd acquisition and conditioning circuit 3 acquisition module of sending into microprocessor, gathers Module continuous sampling n times are also converted into real engine temperature engine_temp after digital quantity AD medium filtering；
S4: flow transducer is through the 4th acquisition and conditioning circuit 4 acquisition module of sending into microprocessor, and acquisition module is even Continuous sampling n times also save as flow by being converted into actual flow value after digital quantity AD medium filtering；
S5: definition igbt maximum operating temperature is max_igbt, and temperature threshold when needing to open water-cooled is igbt_ Warn, then calculate igbt cooling requirement flow
Flow1*=(inv_temp-igbt_warn) ÷ (max_igbt-igbt_warn)；
S6: definition motor maximum operating temperature is max_motor, and temperature threshold when needing to open cooling is motor_ Warn, then calculate motor cooling requirement flow
Flow2*=(motor_temp-motor_warn) ÷ (max_motor-motor_warn)；
S7: definition electromotor maximum operating temperature is max_engine, temperature threshold when needing to open cooling is Engine_warn, then calculate engine cool demand volume
Flow3*=(engine_temp-engine_warn) ÷ (max_engine-engine_warn)；
S8: detection temperature sensor fault temp_fault is for 1, if 1 arranges temperature sensor fault cooling and needs Seeking flow is flow4*=N1；
S9: compare cooling requirement flow flow1*, flow2*, flow3*, flow4* size and take maximum and save as flow*；
S10: judge whether flow transducer fault flow_fault is 1, if 1 fixing output pwm is M, if 0 will Flow* and actual flow flow does difference and sends into actuator PI1, PI1 output duty cycle pwm1；
S11: dutycycle pwm obtained in step S10 drives water pump pwmp to reach the effect that cools.
The present invention possesses following beneficial effect:
The hybrid electric vehicle cooling system control method that the present invention provides can be in the case of water pump consumes minimum Motor is cooled down by the operating flux ensureing cooling water pump of limits.
Certainly, the arbitrary product implementing the present invention it is not absolutely required to reach all the above advantage simultaneously.
