The device is a device corresponding to the method embodiment applied to the air conditioner controller, all implementation manners in the method embodiment are applicable to the embodiment of the device, and the technical effects same as those of the method embodiment can be achieved. To avoid repetition, further description is omitted here.
In addition, the invention also provides an automobile which comprises the temperature control system.
The temperature control method of the present invention will be described below with reference to fig. 7.
In fig. 7, the temperature (a first temperature value) of the working environment where the smart antenna is located is sensed by the smart antenna temperature sensor, when the first temperature detected by the smart antenna temperature sensor is higher than a first temperature threshold (which can be calibrated, for example, 80 ℃), the temperature sensor inside the smart antenna sends temperature information to the ECC, the ECC performs further verification and confirmation according to the temperature sensor of the air conditioner itself, and if the temperature does exceed the first temperature threshold (for example, 80 ℃), the ECC sends a command to control the blower to be turned on, and simultaneously sends a command to the EAS to turn on the air conditioner compressor to cool the vehicle interior; further, when the temperature sensor of the smart antenna and the temperature sensor of the air conditioner detect that the temperature in the vehicle drops to a second temperature threshold (which can be calibrated, for example, 75 ℃), the ECC controls to turn off the blower and the air conditioner compressor EAS.
In addition, if the trolley is not used by the owner for a long time, the trolley is exposed to a high-temperature environment for a long time, the control logic repeatedly appears within a few days, and the SOC of the battery pack is gradually reduced. When the BMS detects that the SOC of the large battery pack is lower than a first electric quantity threshold value (which can be calibrated, such as 5%) of a certain value, the BMS sends the SOC electric quantity to a mobile phone APP through the GW and the T-BOX to remind a vehicle owner, so that the vehicle can be ensured to be charged in time, and meanwhile, when the sufficient electric quantity is not obtained, the air conditioner is forbidden to be automatically started. Through the scheme, the problem that the vehicle cannot be started and started after the air conditioner is started again due to the fact that the electric quantity of the battery is too low can be effectively avoided.
In the above scheme, for ensuring that the intelligent antenna can be used under the high-temperature condition, the cost is effectively reduced, the technical advantages are further improved, the temperature value of the working environment where the intelligent antenna is located is obtained, and the scheme of automatically controlling the temperature in the vehicle by the air conditioning system is provided according to the temperature value of the working environment where the intelligent antenna is located. This scheme can ensure that smart antenna replaces traditional antenna and can normally use under high temperature environment, and bicycle reducible cost 180 yuan/platform truck. Meanwhile, the temperature in the car is intelligently adjusted, a new thought is opened for the pets and the like in the car, and the safe survival of the pets can be ensured.
While the preferred embodiments of the present invention have been described, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention as defined in the following claims.
