Abstract
Hybrid electric vehicle cooling water circulation control system, comprise motor, radiator, controller and the water route in parallel being formed by motor water pump, engine water pump, one-way valve and tee union, motor, radiator and water route in parallel are in turn connected to form circulation waterway, described motor sends signal to controller, controller control motor pump working.Adopt the technical solution of the utility model, by detecting the working state of working state control water pump of motor.This technological scheme volume is small and exquisite, simple in structure, cheap, can protect the engine cooling water moment to keep flowing state, makes the motor moment keep normal heat radiation, extends the working life of motor and inner member, guarantees the safety of motor.
Description
Technical field
The utility model relates to a kind of hybrid electric vehicle cooling water circulation control system.
Background technique
Hybrid-power bus refers to the car with motor and two kinds of power output systems of motor, and when idling flameout function refers to the speed of a motor vehicle lower than critical value, vehicle is driven separately by motor, and motor, in flameout state, does not have power output.When the speed of a motor vehicle is during higher than critical value, motor starts automatically, with the common outputting power of motor.When engine operation outputting power, also can produce the process that a large amount of heats, especially fuel oil burn in cylinder, in engine working process, need, by continuing circulating water cooling, to guarantee that motor keeps suitable temperature.
Conventional engine water cooling system carries water pump by motor power is provided, and promotes that cooling water circulates between engine cylinder-body and radiator, takes away the heat of motor.The hybrid electric vehicle with idling flameout function is because the speed of a motor vehicle is decelerated to critical value when following, motor auto extinguishing, the water pump that now motor carries quits work, and cooling water stops circulation, cause temperature in engine cylinder-body not distribute in time, cause local temperature sharply to raise.Bus need to be stopped by fixed line, fixed station, and high low speed is switched frequent, and therefore motor need to stop working frequently, and the temperature of accumulating over a long period rises sharply the safe handling to motor is caused to hidden trouble.
Model utility content
The technical problems to be solved in the utility model is to provide a kind of control system of hybrid electric vehicle cooling water circulation for having idling flameout function.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: hybrid electric vehicle cooling water circulation control system, comprise motor, radiator, controller and the water route in parallel being formed by motor water pump, engine water pump, one-way valve and tee union, motor, radiator and water route in parallel are in turn connected to form circulation waterway, described motor sends signal to controller, controller control motor pump working.
Further, described water route in parallel is made up of motor water pump, engine water pump, two one-way valves and two tee unions, described radiator, motor, the first tee union, the first one-way valve, motor water pump and the second tee union are in turn connected to form the first circulation waterway, and described radiator, motor, the first tee union, the second one-way valve, engine water pump and the second tee union are in turn connected to form the second circulation waterway.
Adopt the technical solution of the utility model, by detecting the working state of working state control water pump of motor.This technological scheme volume is small and exquisite, simple in structure, cheap, can protect the engine cooling water moment to keep flowing state, makes the motor moment keep normal heat radiation, extends the working life of motor and inner member, guarantees the safety of motor.
Brief description of the drawings
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
Fig. 1 is logic diagram of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
The cooling water circulation of hybrid electric vehicle shown in Fig. 1 control system, comprise motor, radiator, controller and the water route in parallel being formed by motor water pump, engine water pump, one-way valve and tee union, motor, radiator and water route in parallel are in turn connected to form circulation waterway, described motor sends signal to controller, controller control motor pump working.Described water route in parallel is made up of motor water pump, engine water pump, two one-way valves and two tee unions, described radiator, motor, the first tee union, the first one-way valve, motor water pump and the second tee union are in turn connected to form the first circulation waterway, and described radiator, motor, the first tee union, the second one-way valve, engine water pump and the second tee union are in turn connected to form the second circulation waterway.After car load power connection, controller and Engine ECU are by the CAN transmission of information of communicating by letter, detect in real time work state information and the cooling water temperature information of motor, when motor is during in normal working, controller control motor water pump, in the state of quitting work, drives cooling water circulation by engine water pump; When motor is in the time that flameout state and water temperature are greater than setting value, engine water air pump inoperative, the work of electric water pump, the continuing of continuity cooling water circulates.In whole control procedure, the lower moment of situation that the cooling water temperature in engine-cooling system is greater than setting value keeps circulating state, and guarantee engine operation, in suitable temperature range, is guaranteed the safe handling of motor.
Although specifically show and introduced the utility model in conjunction with preferred embodiment; but those skilled in the art should be understood that; not departing from the spirit and scope of the present utility model that appended claims limits; in the form and details the utility model is made a variety of changes, be protection domain of the present utility model.
