Abstract

The present invention relates to a winter vehicle thawing method, and to operate the engine and the heater by a remote control key, to detect the external temperature of the vehicle by using a sensor and to detect the internal temperature of the vehicle when the value is less than 0 ℃ Then, operate the hot wires of the keyhole, steering wheel cover and seat cover and compare their temperature with the vehicle's room temperature value and stop the operation of the hot wire by the ECU when it is higher than the appropriate temperature value (A1, A2, A3). It is to be made, by thawing each vehicle freezes before boarding the winter vehicle, the door can be opened quickly and easily, as well as drastically reduce the difference in sensation temperature with the outside to improve driving convenience.

Description

How to thaw winter vehicles

The present invention relates to a winter vehicle thawing method, in particular, by operating the engine and the heater by the winter remote control key, using the sensor to detect the outside temperature of the vehicle and the value is less than 0 ℃ internal temperature of the vehicle After detecting, the hot wire of the keyhole, steering wheel cover and seat cover is operated to stop the operation of the hot wire by ECU (Electronic Control Unit) By allowing them to thaw each part of the car before freezing in the winter season and to increase the indoor temperature, the door can be opened quickly and easily, as well as to drastically reduce the difference in sensational temperature with the outside. A method for thawing a vehicle.

In general, in winter, such as winter, the key holder is often frozen by snow or water, and in this case, the key cannot be inserted or operated, so the door cannot be opened quickly.

In addition, the indoor temperature is a low temperature without a great difference from the outdoor temperature, there was a disadvantage that accompanied by cold during the initial boarding.

Accordingly, the present invention provides a winter vehicle thawing method that can quickly and easily thaw a frozen key holder using a remote control key and at the same time increase the indoor temperature to smoothly move a key and open a door. have.

In order to achieve the above object, the present invention is to turn on the engine and the heater by a remote control key, and detect the external temperature of the vehicle using a sensor, and detect the internal temperature of the vehicle when the value is less than 0 ° C. Next, the hot wires of the key hole, the steering wheel cover, and the seat cover are operated to compare their temperatures with the indoor temperature of the vehicle, and when the heat is greater than that, the ECU stops the operation of the hot wires. It is characterized by the ability to thaw each part of the entire vehicle.

1 is a flow chart according to the present invention

When described in detail with reference to the accompanying drawings a preferred embodiment of the present invention as follows.

Figure 1 shows a flow chart according to the present invention, first of all, the present invention can remotely start the vehicle by the remote control key, the hot wire is mounted on the key hole, the steering wheel cover and the seat lower, The vehicle is equipped with an indoor or outdoor temperature sensor (Incar thermo sensor, ambient thermo sensor), and the engine is turned on by operating the remote control key, and the outside of the vehicle is operated with the heater operated by the same remote control key. The external temperature TA is detected by a temperature sensor mounted on the sensor.

If the outside temperature TA of the vehicle is less than 0 ° C., the inside temperature TI of the vehicle is detected by the temperature sensor mounted inside the vehicle and applied to the E.C.U, and the hot wire of the steering wheel cover is operated.

In addition, the ECU continuously receives the internal temperature value (TI) detected by the in-vehicle temperature sensor and compares and examines each part (inside the keyhole and steering wheel) by comparing with the values A1, A2, and A3 calculated by experiments. Indicates whether the cover and the bottom of the seat is heated.

It is preferable that E.C.U is basically an independent system dedicated to the determination and instruction of the operation and stop of the heating wire installed on the key holder, the steering wheel and the seat.

On the other hand, if the indoor temperature (TI) of the vehicle is smaller than those compared to the set temperatures A1 ℃, A2 ℃, and A3 ℃ in the state that each keyhole, steering wheel cover, and seat are operating with heating, the heating operation by ECU is terminated. And the indoor temperature (TI) of the vehicle is compared with A1 ° C, A2 ° C, and A3 ° C, and if it is larger than them, the heating wire heating by the ECU is continuously performed.

In addition, when the external temperature TA of the vehicle is greater than 0 ° C., the engine is turned on and waits.

Thus, by heating and thawing the winter key holder, steering wheel cover and the lower part of the seat by hot wire, the door can be opened quickly and easily, as well as creating a warm and comfortable environment of the vehicle.

On the other hand, the internal temperature (TI) is compared with A1, A2, and A3 ° C, which are detected at different values, and the part which reaches the reference temperature preferentially is instructed by the ECU to stop the hot wire operation. When A1, A2 and A3 ° C are satisfied, all systems are turned off by command of the ECU.

As described above, according to the present invention, the engine and the heater are operated and turned on by a remote control key, and the external temperature of the vehicle is detected by using a temperature sensor and the internal temperature of the vehicle is detected when the value is less than 0 ° C. Next, the hot wires of the key hole, the steering wheel cover, and the seat cover are operated so that the operation of the hot wires is stopped by the ECU when the indoor temperature value of the vehicle is greater than the proper temperature value. By thawing each part, the door can be opened quickly and easily, as well as the indoor temperature is greatly reduced to reduce the difference in sensational temperature with the outside, and at the same time, the driving convenience of the vehicle is improved in a comfortable state.
