Description
Technical field
The utility model belongs to automotive control circuit, particularly a kind of control circuit of oil pump of auto motor.
Background technique
The generation of electronic oil pump relies on greatly developing of Power Electronic Technique, is originally changed into by motoring by engine-driven oil pump, has changed the driving source of oil pump, has saved the energy of motor.And the height of electric motor oil revolution speed is entirely by motor control, when its problem is just the exploitation speed of motor, is everlasting and switches at a high speed and between low speed, and the rotating speed of motor relies on supply voltage, in the time that the especially high and low rotating speed of rotating speed of engine speed and motor is inconsistent, directly cause following two kinds of situations:
1, engine speed is low, and the rotating speed of motor (motor on electronic oil pump) is high, causes electronic oil pump excessive to the machine oil supply of motor, and the too much electric energy of motor high speed rotating consumption and motor body are easily overheated.
2, engine speed is high, and motor speed is low, causes electronic oil pump under-supply to the machine oil of motor, can not meet motor to lubricated and cooling needs.
For above-mentioned two situations, all can threaten the normal operation of motor.
Model utility content
Technical problem to be solved in the utility model is for electronic oil pump in prior art and the inconsistent defect of engine speed, and a kind of control circuit of the oil pump of auto motor that overcomes above-mentioned defect is provided.
In order to solve the problems of the technologies described above, the utility model provides following technological scheme: a kind of control circuit of oil pump of auto motor, comprise the storage battery, relay, the Engine ECU that connect successively, and also comprise electronic oil pump ECU and electronic oil pump; Wherein, relay is connected with Engine ECU power end and oil pump ECU power end respectively, and the signal output part of Engine ECU is connected with the signal input part of electronic oil pump ECU, and oil pump ECU power output end connects electronic oil pump.
Working principle of the present utility model is as follows: storage battery is powered to Engine ECU by relay, Engine ECU is switched on and is monitored, gathers the rotating speed of motor, in the time that engine speed is high, Engine ECU signal output part output high potential signal, electronic oil pump ECU receives this signal, according to this signal is sent to instruction, electronic oil pump ECU power output end output 12V(is equivalent to battery tension) power supply is to electronic oil pump, and electronic oil pump is run up.In like manner known, engine speed is low, Engine ECU signal output part output low-potential signal, electronic oil pump ECU receives this signal, according to this signal is sent to instruction, electronic oil pump ECU power output end output 9V(is lower than battery tension) power supply is to electronic oil pump, makes electronic oil pump low-speed running.
The beneficial effects of the utility model are as follows: Engine ECU signal output part output high potential signal, electronic oil pump ECU receives this signal, according to this signal is sent to instruction, 12V is to electronic oil pump for the output of electronic oil pump ECU power output end, electronic oil pump is in the state of running up, to meet motor to lubricated and cooling needs; When motor is during in low speed, low load operation, Engine ECU signal output part output low-potential signal, electronic oil pump ECU receives this signal, according to this signal is sent to instruction, electronic oil pump ECU power output end output 9V, electronic oil pump is in low-speed running state, and to reduce the consumption to electric energy, that avoids that motor runs up and produce is overheated simultaneously.
Further, between described electronic oil pump ECU power output end and Engine ECU power end, be also connected with inspection connector.Check that connector is for checking the motor element quality of electronic oil pump, in the time that electric motor oil pump circuit breaks down, directly short circuit checks the two ends of connector, and storage battery is directly given the power supply of electric motor oil pump motor, checks that whether motor work is normal.
Further, between described relay and storage battery, be connected with safty device.Safty device can be avoided, in the time that this circuit breaks down or be abnormal, being accompanied by electric current and constantly raising, and the electric current raising likely damages relay in circuit or even the ECU element of motor, also likely burn circuit and even cause the defect of fire.
Further, described safty device are insurance fuse.Safety fuse cutout will be when current anomaly be elevated to certain height and temperature, and self fuse and cut off electric current, thereby play the effect of protective circuit safe operation, and its low price, it is convenient to change.
Further, also comprise the noise transducer and the temperature transducer that are connected with Engine ECU signal input part, described noise transducer and temperature transducer are arranged on motor place; Engine ECU is also connected with audible-visual annunciator.Under normal state under (oil pump and motor are all normally worked), the heat basicly stable (lubricated, antirust and cooling effect that machine oil has) that motor produces, the electrical signal that noise transducer produces should be the cyclical signal corresponding with engine behavior; If oil pump operation irregularity, the temperature of motor there will be significant change, Engine ECU detects after this abnormal temperature signal, give and close the noise signal that noise transducer detects (because machine oil provides lubrication for motor, if oil pump operation irregularity, motor place there will be more irregular hum) judge that whether normally and whether need to start audible-visual annunciator whole motor-oil pump device working state.
