1 and 2, the vehicle interior temperature control system before the vehicle running of the present invention, a wireless signal receiver receiving a signal of the approved wireless key 30, and a door open signal (Door) from the wireless signal receiver (Door) A door lock device 23 which releases the door lock state by receiving an open signal, and sends door open information to the vehicle internal temperature controller 40, and a vehicle internal temperature sensor 11 capable of sensing the vehicle internal temperature; The vehicle air conditioning means may control the internal temperature of the vehicle according to the vehicle external temperature sensor 10 capable of sensing the vehicle external temperature and the temperature value detected by the vehicle internal temperature sensor and the vehicle external temperature monitoring sensor. It is configured to include a vehicle internal temperature controller 40 for controlling the operation.

In this case, as the wireless key 30, a remote keyless entry (RKE) system, a remote engine start system, a smart key, an RFID embedded key, and the like are applied.

The vehicle air conditioner may include a power window 24 capable of opening and closing a window by electric force, or an air conditioner 25 for controlling the indoor temperature of the vehicle through cooling and heating of the air inside the vehicle using a refrigeration cycle.

On the other hand, the vehicle interior temperature control system before the vehicle running, is turned on (ON) by receiving a control signal of the vehicle internal temperature controller 40 when the door is opened, the vehicle internal temperature sensor, the vehicle external temperature sensor, power It further includes an ignition 21 for activating the window 24 and the air conditioner 25.

The door locking device 23 is electrically connected to the key cylinder switch so as to detect the switch open state of the key cylinder 22 when the door is directly opened with the approved vehicle key.

Meanwhile, the reception control device 32 (Remote ECU) is connected to the radio receiver 31 (LF transceiver or RF receiver), and the vehicle battery 20 is connected to the ignition 21.

Referring to the control process of the vehicle internal temperature system before driving the vehicle of the present invention configured as described above is as follows.

First, when the wireless key 30 (for example, a remote keyless entry system, a remote engine start system, a smart key, an RFID built-in key, etc.) approved for wirelessly opening a vehicle door is operated, a low frequency (LF) Alternatively, the radio receiver 31, which is an RF (Radio Frequency) demodulator, transmits the demodulated signal to the reception control device 32.

The reception control device 32 sends a door open signal to the door lock device 23. In response to the door open signal, the door lock device 23 releases the door lock state of the vehicle and transmits the unlock state of the door to the vehicle internal temperature controller 40.

When the vehicle interior temperature controller recognizes the information about the unlock state of the door, the vehicle interior temperature controller 40 turns on the ignition 21, and as the ignition 21 is turned on, 11) and the vehicle external temperature sensor 10 operates to send the vehicle internal and external temperature to the vehicle internal temperature controller 40, and the air conditioner 25 is also turned on to transmit the set temperature value to the vehicle internal temperature controller ( Send to 40).

Accordingly, the vehicle internal temperature controller 40 receives the temperature values of the vehicle internal temperature sensor 11 and the vehicle external temperature sensor 10 and the set temperature values of the air conditioner 25 and the power window 24. The operation of the air conditioner 25 is determined.

Meanwhile, the operation of the power window 24 and the air conditioner 25, which are vehicle air conditioning means for controlling the temperature inside the vehicle before driving the vehicle, will be described in detail.

In the operation of the vehicle air conditioning means, for example, the air conditioner 25 may be adjusted according to the temperature inside and outside the vehicle and the temperature difference between the inside and the outside, and the air volume and the intensity of the air conditioner 25 may be adjusted. When exceeding a predetermined range, the air volume and intensity of the air conditioner 25 can be maximized.

In addition, while the air volume of the air conditioner 25 is maximized, the air volume can be adjusted to be close to a desired temperature (that is, a set temperature set in the air conditioner) by gradually decreasing within a predetermined operating time.

When there is almost no temperature difference between the inside and the outside of the vehicle, that is, when the temperature difference between the inside and the outside of the vehicle is within a predetermined range and the internal temperature is higher than the set temperature, the vehicle air conditioner is operated regardless of the temperature difference between the inside and the outside of the vehicle. Can be controlled to be adjusted.

That is, when there is little difference between the inside and outside of the vehicle, the air conditioner 25 is properly operated so that the difference is resolved by comparing the internal temperature 11 with the desired temperature. The air conditioner operating criterion of the air conditioner 25 is determined by the difference between the reference temperature and the internal temperature.

As such, when the vehicle indoor temperature reaches a desired temperature by the operation of the air conditioner 25, the vehicle can be started. However, the idling time of the vehicle cannot legally exceed 3 minutes, so the above operation does not exceed 3 minutes.

However, the vehicle interior temperature sensor 11 is a position where it becomes a barometer of the overall temperature of the vehicle interior, that is, a position where the temperature inside the vehicle can be correctly detected without distortion, for example, a rear seat away from the air conditioner 25 (for example, the rear seat). Should be mounted on the

Hereinafter, a control process of opening a door using an approved vehicle key instead of a wireless key in the control process of the vehicle internal temperature control system of the present invention will be described.

First, when the driver opens the door by inserting and operating the vehicle key into the key cylinder 22 of the door, the door open state is detected by the key cylinder switch.

In addition, the door open detection signal of the key cylinder switch is transmitted to the vehicle internal temperature controller 40, and the vehicle internal temperature controller 40 controls the vehicle internal temperature in the same process as when the door is opened by the wireless key 30 described above. Will be done.

That is, the vehicle internal temperature controller 40 turns on the ignition 21, followed by temperature values of the vehicle internal temperature sensor 11 and the vehicle external temperature sensor 10, and the set temperature of the air conditioner 25. By receiving a value to determine whether the vehicle air conditioning means such as the power window 24 and the air conditioner 25 to control the operation of the vehicle air conditioning means.

For reference, the design temperature and operating temperature of all vehicle parts mounted in the vehicle cabin are generally -40 ° C to 85 ° C. On the other hand, the operating temperature of the display units applying the vehicle LCD is -30 ℃ to 85 ℃. If the LCD is out of the operating temperature range, anomalies such as color change of the LCD screen may occur. Plastic parts applied to vehicles are generally more susceptible to deformation and abrasion of parts when they are operated at a state where the heat deformation temperature exceeds 85 ° C. but left at a high temperature for a long time.

Therefore, the necessity of the in-vehicle temperature control system and its control method before driving is very high.

As described above, the present invention by appropriately adjusting the vehicle internal temperature by using the information on the internal and external temperature and the internal and external temperature difference obtained from the vehicle external temperature sensor 10 and the vehicle internal temperature sensor 11 before driving the vehicle. In addition, it is possible to increase the vehicle performance and the driver's convenience by preventing the malfunction, deformation and wear of the internal parts of the vehicle caused by the vehicle running at an excessive temperature while making the driving environment comfortable.

Meanwhile, the present invention is not limited to the above-described embodiments, and various changes and modifications can be made without departing from the scope of the technical spirit of the present invention. For example, in the operation of the air conditioner 25 which is a vehicle air conditioning means, the air conditioner 25 may be operated and the air volume and intensity control may be performed using only the temperature inside the vehicle without considering the external temperature of the vehicle. That is, when the temperature value inside the vehicle is more than a predetermined size, the air conditioner can be operated to adjust the temperature inside the vehicle before driving.

Accordingly, the rights of the present invention are not limited to the embodiments described above, but are defined by what is stated in the claims, and those skilled in the art can make various modifications and adaptations within the scope of the claims. It is self evident.

The present invention not only makes the driver's comfort and driving environment comfortable, but also improves the durability of all the components mounted in the vehicle interior, and thus the invention is highly industrially applicable.
