Afterwards, preceding defogging mode is switched to according to the second status command control model air door.Such a mode hazes suitable for rainy day vehicle window,
The larger situation of outside humidity.
When air-conditioner controller generates the second status command and the third state instructs, status command is sent to vehicle-mounted sky
Adjust so that the step of on-board air conditioner carries out defogging operation according to status command includes：
Second status command is sent to the pattern damper motor to mounted air conditioner system so that pattern damper motor according to
The pattern air door that the control of second status command is connected with pattern damper motor switches to preceding defogging mode；
Third state instruction is sent to the inlet flap motor in mounted air conditioner system so that inlet flap motor according to
Third state instruction control and the inlet flap of inlet flap motor connection switch to outer circulation state.
Specifically, the second status command is sent to the pattern damper motor being connected with air-conditioner controller, pattern air door electricity
Machine is connected with pattern air door, and after pattern damper motor receives the second status command, mould is controlled according to the second status command
Formula air door switches to preceding defogging mode.Such a mode is applied to the larger situation of outside humidity.
Third state instruction is sent to the inlet flap motor being connected with air-conditioner controller, inlet flap motor and air inlet
Air door connects, and after inlet flap motor obtains third state instruction, control inlet flap switches to outer circulation state, using room
Air-conditioning in outer cold air drying cart, reaches effect on moisture extraction.Such a mode is applied to the situation of cold air dehumidifying.
Wherein, in embodiments of the present invention, this method also includes：
After receiving the detection information that detection device is sent, receive entire car controller and be more than in the electricity of battery management system
What is sent during power threshold allows to instruct；After acquisition allows instruction, generate status command and send to mounted air conditioner system.
Whether after air-conditioner controller receives the detection information that detection device is sent, being sent to entire car controller allows to open
First instruction of on-board air conditioner, entire car controller is after the first instruction is received, according to the first command detection and full-vehicle control
The information about power of the battery management system of device connection, when the electricity of battery management system is more than power threshold, entire car controller
Feed back allowing on-board air conditioner to open to air-conditioner controller and allow to instruct in response to the first instruction, air-conditioner controller is connecing
Receive entire car controller feedback allow instruction after, according to the detection information of acquisition generate status command, status command is sent out
Deliver to on-board air conditioner so that on-board air conditioner carries out defogging operation.When the electricity of battery management system is less than power threshold, vehicle
Controller feeds back not allowing on-board air conditioner to open and forbids instructing in response to the first instruction to air-conditioner controller, now car
Carrying air-conditioning system can not start.
The workflow of the embodiment of the present invention is as shown in Figure 6：
Step 601, on vehicle in the case of electricity, Defog-Switch before user opens.
Whether the rain shaving electrical machine that step 602, detection are connected with windscreen wiper is opening.
When rain shaving electrical machine is in opening, show that windscreen wiper is kept in motion, step 603 is now performed, in windscreen wiper
When motor is closed, show that windscreen wiper is in non-athletic state, now perform step 604.
Step 603, air-conditioner controller control on-board air conditioner open compressor and carry out dehumidification operation, while control model air door
Motor works, and then control model air door switches to preceding defogging mode.
Step 604, in the case where vehicle is in travel condition, judge whether the temperature information outside car is less than preset temperature threshold value.
(preset temperature threshold value here can be 5 degrees Celsius, art technology when temperature information outside car is less than preset temperature threshold value
Personnel can be set according to the actual requirements), step 605 is performed, otherwise performs step 606.
Step 605, air-conditioner controller open inlet flap motor and pattern damper motor, inlet flap motor control air inlet
Air door switches to outer circulation state model, carries out cold air drying using outer circulation, pattern damper motor control model air door is cut
Shift to preceding defogging mode.
Step 606, control inlet flap motor and pattern damper motor are closed.
The operation method of air-conditioner control system provided in an embodiment of the present invention, mainly by increasing special demisting logic, and
