Abstract

The utility model provides a kind of control circuit for electric automobile air conditioner; including automobile air conditioner compressor and ptc heater; described automobile air conditioner compressor and ptc heater input are connected to entire car controller VCU by output interlocking; input signal interlock protection circuit is then connected to, finally by manual input switches control;A termination speed adjusting resistance, other end earthing potential GND1 in described manual input switches;Entire car controller VCU is reconnected has PTC to heat switch.The utility model changes electrical equipment and is mutually locked in entire car controller VCU input sides, avoid entire car controller VCU software and hardwares to go wrong, the problem that cannot be found, has concatenated interlock relay in entire car controller VCU output ends, the circuit loop for controlling ptc heater and air-conditioning.If so entire car controller VCU inputs and output increase electrical equipment interlocking simultaneously, the functional reliability of PTC warm braws and air-conditioning will be increased substantially.

Description

A kind of control circuit for electric automobile air conditioner
Technical field
The utility model is related to the air-conditioning system of electric automobile, specifically a kind of control electricity for electric automobile air conditioner Road.
Background technology
Nearly 2 years Electric Cars in China yield is in blowout situation, and in electric automobile air conditioner, heater block is PTC electric heater, The hot-water heating heating danger for comparing orthodox car improves, 90 degrees Celsius traditional of water heats maximum temperature, and PTC heating Device surface temperature in blower fault can reach 240 degrees Celsius, may burn out air-conditioning plastic casing, or even cause burning car thing Therefore.
Because electrokinetic cell limited energy, if unlatching air-conditioning and PTC warm braws are unfavorable for energy-conservation, but New energy electric simultaneously Car air-conditioning and ptc heater are all power controls, it is possible to cause air-conditioning and ptc heater while the possibility of work.For this Typically all increase air-conditioning and ptc heater interlock circuit, and after being all added in hand switch;But air-conditioning and PTC are except receiving Control to hardware circuit, also controlled by entire car controller VCU softwares, so as to further energy-conservation.VCU soft projects amount is big, difficult Exempt to have software defect, PTC warm braws and air-conditioning is caused while the phenomenon of unlatching.And software issue is typically difficult to check.In addition, by Belong to high-voltage large current working method in new forms of energy car, electromagnetic environment is relatively poor, EMC interference problems are than more serious.If Entire car controller VCU is interfered in abnormality, however not excluded that the phenomenon that PTC warm braws and air-conditioning are opened simultaneously.
Content of the invention
In order to improve vehicle air conditioning and warm braw control reliability, only one of which device exists synchronization the utility model all the time Work, spy propose a kind of control circuit for electric automobile air conditioner.
For this technical solution of the utility model it is, a kind of control circuit for electric automobile air conditioner, empty including automobile Adjust compressor and ptc heater, it is characterised in that:Described automobile air conditioner compressor and ptc heater input are by output Interlocking connection is then connected to input signal interlock protection circuit to entire car controller VCU, finally by manual input switches control System.
Further it is improved by:A termination speed adjusting resistance, other end earthing potential in described manual input switches GND1.
Further it is improved by:Described entire car controller VCU is reconnected has PTC to heat switch.
Beneficial effect:
In order to eliminate, PTC temperature is too high to cause the hidden danger for burning car to the utility model, selects to be manually entered in air-conditioning circuit Signal of peculiar ground potential GND1 in switch as start and stop air-conditioning, this peculiar ground potential GND1 ability when air blast has wind speed Be connected to ground potential, this ground potential led to vehicle body relay box, can accomplish air blast could use when having a wind speed PTC or Person's compressor of air conditioner.
This signal is hanging when air blast is calm, is 1,2,3,4 fourth gear wind in manual input switches when there is wind It is ground connection when fast, this signal is drawn the basis started as control ptc heater or compressor of air conditioner.
Freeze in air conditioning for automobiles and heat while running and can waste the energy, in order to avoid such case occurs, in air conditioner electric Increase output interlocking in road, switch is heated in PTC and air conditioner refrigerating is switched while cooling and warming can be allowed when pressing not work.
Ptc heater enabling signal and the mutual lock control of compressor of air conditioner enabling signal, when PTC heater switch and air-conditioning system It is all invalid to freeze when cold switch is pressed simultaneously and heat, and can thus remind the driver should not be while pressing PTC heater switch Switch with air conditioner refrigerating, it is also possible to prevent cooling and warming while effectively causing energy waste.
The utility model changes electrical equipment and is mutually locked in entire car controller VCU input sides, it is to avoid entire car controller VCU softwares Go wrong with hardware, it is impossible to the problem of discovery, in entire car controller VCU output ends, control the circuit of ptc heater and air-conditioning Interlock relay has been concatenated in loop.If so entire car controller VCU inputs and output increase electrical equipment interlocking, will significantly simultaneously Degree improves the functional reliability of PTC warm braws and air-conditioning.
Description of the drawings
Fig. 1 is block diagram of the present utility model.
Fig. 2 is circuit theory diagrams of the present utility model.
In figure, 1 is automobile air conditioner compressor, and 2 is PTC controllers, and 3 is output interlocking, and 4 is entire car controller VCU, and 5 is defeated Enter signal interlock protection circuit, 6 is manual input switches, and 7 is that PTC heats switch, and 8 is speed adjusting resistance, and GND1 is ground potential.
Specific embodiment
The utility model is as shown in Fig. 1/2.
A kind of control circuit for electric automobile air conditioner, including automobile air conditioner compressor 1 and ptc heater 2, automobile is empty Adjust compressor 1 and 2 input of ptc heater entire car controller VCU 4 to be connected to by output interlocking 3, be then connected to input letter Number interlock protection circuit 5, controls finally by manual input switches 6.
A termination speed adjusting resistance 8, other end earthing potential GND1 in manual input switches 6.
Entire car controller VCU 4 is reconnected has PTC to heat switch 7.

Claims (3)
