Description
Technical field
The utility model relates to a kind of electric vehicle control system, specifically a kind of electric motor car cool electronic control system of water pump.
Background technique
The effect of existing cooling system for electric vehicle is car load drive motor for electric motor car and the cooling of car load electric machine controller, and the water flow of cooling water is that the logical dutycycle saving electronic water pump regulates in cooling system, for controlling in the electronic water pump control system of electronic water pump, only a temperature transducer is set in the car load electric machine controller of electric motor car, what adopt is the temperature that single point temperature sensor gathers whole cooling system, electric motor car control unit reads single-point water temperature transducing signal, and Logic judgment is carried out to this signal, export control signal to regulate the dutycycle of electronic water pump or switch.Find in actual use, single point temperature signal can not reflect the actual temperature of cooling system for electric vehicle accurately, and the dutycycle of electronic water pump and the virtual condition of car load may exist unmatched situation; Monitoring temperature is not carried out to thermally sensitive original papers such as the winding of car load drive motor, the IGBT (insulated gate bipolar transistor) of car load drive motor controller simultaneously, the risk that the original paper such as motor, controller is overheated may be caused.
Summary of the invention
The object of the invention is to solve the problems of the technologies described above, provide a kind of structure simple, control easy, energy-saving and cost-reducing electric motor car cool electronic control system of water pump.
Technological scheme comprises electric motor car control unit, the input end of described electric motor car control unit is connected with temperature transducer, output terminal is connected with electronic water pump controller, the output terminal of described electronic water pump controller is connected with electronic water pump, described temperature transducer has three, first temperature transducer is arranged on car load and drives on motor, second temperature transducer is arranged in car load drive motor controller, three-temperature sensor is arranged on car load drive motor cooling liquid water outlet, and described three temperature transducers are all connected with the input end of electric motor car control unit.
Described first temperature transducer is for monitoring the temperature at car load drive motor (winding position), second temperature transducer is for monitoring the temperature of the core component IGBT of car load drive motor controller, three-temperature sensor is for monitoring the coolant temperature of drive motor cooling liquid water outlet, and three temperature signals are sent to electric motor car control unit (being called for short EVCU), electric motor car control unit compares with the temperature preset according to the temperature signal accepted, and carry out logical operation, corresponding electronic water pump control signal is exported after making comprehensive descision according to the difference of heat load, and electronic water pump control signal is passed to electronic water pump controller by CAN line, thus the dutycycle of the sub-water pump of automatic control electric or switch, this control procedure is more scientific and reasonable, be beneficial to and car load is driven motor, the Comprehensive Control of car load drive motor controller and car load drive motor coolant temperature, more energy-conservation.
The utility model system can monitor the temperature of drive motor, drive motor controller and motor cooling liquid in real time; the dutycycle of the electronic water pump of intelligentized control method car load cooling system; thus make car load cooling system be in best water circulation water flow state; under the prerequisite that protection car load original paper normally works; reduce energy ezpenditure as far as possible; the object reducing car load noise can be controlled simultaneously, control more scientific and reasonable, reliability is high, effectively reduce energy consumption.
Accompanying drawing explanation
Fig. 1 is this electric motor car cool electronic control system of water pump scheme of installation
In figure: 1-first temperature transducer, 2-second temperature transducer, 3-three-temperature sensor, 4-EVCU, 5-CAN line, 6-electronic water pump controller, 7-electronic water pump, 8-car load are driven motor, 9-car load drive motor controller, 10-car load drive motor cooling liquid water outlet.
Embodiment
Below in conjunction with accompanying drawing, explanation is further explained to the utility model:
The input end of described EVCU4 (electric motor car control unit) is connected with temperature transducer, output terminal is connected with electronic water pump controller 6 through CAN line 5, the output terminal of described electronic water pump controller 6 is connected with electronic water pump 7, described temperature transducer has three, first temperature transducer 1 is arranged on car load and drives motor 8, second temperature transducer 2 is arranged on car load drive motor controller 9, and three-temperature sensor 3 is arranged on three temperature transducers described in car load drive motor cooling liquid water outlet 10 and is all connected with electric motor car control unit EVCU4 input end.
First temperature transducer 1 is for monitoring the winding temperature of car load drive motor, second temperature transducer 2 is for monitoring the temperature of the IGBT (insulated gate bipolar transistor) of car load drive motor controller, and three-temperature sensor 3 is for monitoring the temperature of drive motor cooling liquid water outlet cooling liquid.
EVCU4 accepts the temperature signal of three temperature transducer inputs simultaneously, and then EVCU4 carries out control logic judgement according to the coherent signal of input, exports electronic water pump control signal.
The electronic water pump control signal that EVCU4 exports passes to electronic water pump controller 6 by CAN line 5, and electronic water pump controller 6 regulates the empty accounting of electronic water pump 7 according to the control signal of input.
