The working process of the embodiment of the invention is as follows:

1. when a user needs to go out, a vehicle traveling request is sent out through a mobile phone of the user in advance. (prefabricated heating and cooling)

And 2, the TBOX receives the request and wakes up the vehicle, and forwards the request to the vehicle body control system and the air conditioning control system.

3. And the vehicle body control system judges whether the current vehicle state is in IGOFF state, the vehicle speed is less than 5KM/H, the vehicle door is fully closed, and the endurance mileage exceeds 50 KM.

4. The air conditioning control system judges whether the ambient temperature outside the vehicle is greater than 28 ℃ or less than 18 ℃. The interval of 28 > x > 18 ℃ is considered as a comfort interval, which is not responsive in view of environmental requirements.

5. And if the conditions 3 and 4 are met, entering a preheating and heating execution flow. At this point an engine start command is sent by TBOX to the engine control system. The vehicle is powered up to a start-up state.

6. The engine is started and an engine start state signal is fed back by an engine control system.

7. And if the engine state signal is in a starting state, the vehicle body control system starts to execute a heating and cooling process.

8. Whether the user enters the vehicle is judged through the change of the door state.

9. If the user enters the vehicle (any vehicle door state changes), the AUTO gear state of the current temperature of the air conditioning system position (namely the highest set temperature or the lowest set temperature, and other air doors or blowers are processed according to an automatic algorithm) is maintained by other actuators, and the current execution state is responded to the user at any time.

10. And if the user does not enter the vehicle, judging whether the time for entering the automatic heating and refrigerating process is overtime.

11. If 10 is not overtime, the judgment is made again.

And 12. if the time is out 10, restoring the state of each actuator before the heating and cooling process. Then the engine is shut down and the power is turned off to a dormant state, and the processing flow is ended.

As shown in fig. 3, the automatic heating and cooling process according to the embodiment of the present invention includes:

1. and judging the current ambient temperature to determine cooling or heating.

When the environmental temperature is higher than 28 ℃, the refrigeration is judged; when the environmental temperature is less than 18 ℃, judging that the heating is carried out;

2. when entering a heating process, the following treatment is carried out:

a. the air conditioner temperature damper is adjusted to the hottest end.

b. The circulation damper is adjusted to the inner circulation.

c. Mode damper adjustment to blow foot defrost

d. The blower is adjusted to an intermediate gear

e. The seat is heated and opened to the maximum gear

f. Steering wheel heating is turned on to maximum gear

3. The method comprises the steps of automatically opening the windscreen wiper for point hanging once, calculating the time from the time when the windscreen wiper is opened to leave a stop position to the time when the windscreen wiper returns to the stop position, and if the time is greater than a threshold value 2S (capable of being calibrated), determining that the vehicle window is slightly snowed; or the windscreen wiper cannot leave the stop position at all due to excessive resistance and is larger than the threshold value 1S (can be calibrated), and the vehicle window is considered to have a large amount of snow.

4. If snow is detected, the front and rear defrosting heating glass is started to execute the snow and ice removing process.

5. If the judgment result 1 is that the refrigeration process is a refrigeration process, the following processing is carried out:

a. air conditioning temperature damper to coldest end

b. The circulating air door is adjusted to the external circulation

c. The mode damper is adjusted to blow the surface

d. The blower is adjusted to an intermediate gear

Examples illustrate that:

the user prepares to go out in winter, opens cell-phone remote control APP in the front 15 minutes of it to open prefabricated refrigerating and heating system of intelligence. And when the T-BOX receives the instruction, starting to awaken the vehicle and judging whether the current vehicle and the environmental condition meet the requirement to start the process. If the current vehicle is in a dormant state, the vehicle speed is less than 5KM/H, the vehicle door is fully closed, the endurance mileage exceeds 50KM, and the ambient temperature is lower than 18 ℃. The flow is allowed to start. At this time, the T-BOX controls the engine control system to start the engine. And then the heating process is confirmed to be started according to a feedback signal of the engine system. When the vehicle is on-board by a user in the preheating process, the preheating output of the vehicle is continuously maintained, the air conditioning system is switched from the preheating mode to the automatic air conditioning mode, and the set temperature of the automatic air conditioning mode is the highest temperature (the highest temperature of the general air conditioner is 32 ℃). And can respond to the user's operation normally. If the preheating time exceeds the threshold value for 30 minutes, the preheating process is automatically stopped and all execution outputs are restored to the states before starting in consideration of energy saving. And finally, stopping the power supply to a dormant state.

In the process, the user can obtain the state feedback of the vehicle in real time through the APP. Such as: vehicle heating/vehicle cooling/vehicle stop flow/start conditions are not met.

The above description is a preferred embodiment of the intellectual development, but the intellectual development should not be limited to the disclosure of the embodiment and the drawings. Therefore, all equivalents and modifications which come within the spirit of the disclosure are desired to be protected.
