In this process, the thicknesses of the lines and the sizes of the components shown in the drawings may be exaggerated for clarity and convenience of explanation. In addition, the terms described below are defined in consideration of the functions of the present invention, which may vary depending on the intention or custom of the user, the operator. Therefore, definitions of these terms should be made based on the contents throughout this specification.

FIG. 1 is a block diagram showing a smart heating device of a vehicle according to an embodiment of the present invention. Referring to FIG. 1, a smart heating device of a vehicle will be described.

1, a smart heating device for a vehicle according to an embodiment of the present invention includes a gear sensing portion 10, a key sensing portion 20, an outside air temperature sensor 30, a rainwater sensor 40, A sensor 50, a storage unit 60, an operation switch 70, a heater 80, a heating wire 90 and an ECU 100. [

The gear sensing portion 10 senses the traveling mode state or the stop mode state of the vehicle. The gear sensing unit 10 senses whether the driver of the vehicle has put the gear on the running D or the stop P and generates a signal. When the mode is changed during execution of the specific mode, To change the signal.

The key detection unit 20 detects the ON / OFF state of the key and outputs a detection signal to the ECU 100. [

The outdoor temperature sensor 30 senses the temperature outside the vehicle and outputs the sensed temperature to the ECU 100. The ECU 100 can determine whether the temperature outside the vehicle is zero or zero through the outside temperature sensor 30.

The rainwater sensor 40 detects rainwater falling on the outside of the vehicle and outputs the rainwater to the ECU 100. For example, the rainwater detection sensor 40 may be installed on the windshield of the vehicle and detect the amount of rainwater by using infrared rays.

The engine temperature sensor 50 measures the temperature of the engine and outputs the measured temperature to the ECU 100. In addition, the engine temperature sensor 50 may include a temperature gauge to display the degree of temperature separately.

The storage unit 60 stores an operation set time for operating the smart heating device of the vehicle received from the user and an internal set temperature for stopping the operation of the smart heating device of the vehicle. The user can input the operation setting time and the internal set temperature through the user setting interface.

In addition, the storage unit 60 may store in advance the degree of rain detection and the operation stop time for stopping the start of operation to determine whether or not the start condition is satisfied. Here, the operation stop time can be set as a reference time for stopping the start for preventing the excessive use of fuel even if the internal temperature of the vehicle does not reach the user set temperature.

The operation switch 70 is a driver input switch, and the smart heating device of the vehicle can be turned on / off according to the operation.

The heater 80 is an indoor temperature control device for a vehicle, and can be disposed on a path through which air supplied to the room from the blower passes. The heater 80 receives power from the power supply unit and generates heat. Therefore, air passing through the heater 80 is heated by heat. The heater 80 may be installed at a front end or a rear end of a heat exchanger (not shown), and is disposed close to a room. The heater 80 may be a PTC (Positive Temperature Coefficient) heater, but is not limited thereto.

The heat ray 90 may be provided on the windshield, rear glass, side mirrors, etc. of the vehicle, respectively. The ECU 100 controls the operation of the hot wire 90 to prevent or melt the ice.

The ECU 100 controls the smart heating device of the vehicle as a whole. ECU 100 determines whether or not the start condition is satisfied in accordance with the operation signal input from operation switch 70. [ At this time, when the operation signal is input, the smart heating device of the vehicle enters the operation wait state. When the operation signal is not inputted from the operation switch 70, the smart heating device of the vehicle is not operated even if the operation set time is reached.

When the operation switch 70 is on and the operation set time is reached, the ECU 100 determines whether the start condition is satisfied. Here, the operation set time refers to a time for operating the smart heating device of the vehicle in order to adjust the internal temperature of the vehicle and remove the ice in advance. For example, if the user intends to board the vehicle at 7 o'clock and sets the operation setting time at 6:50 in advance, the smart heating device of the vehicle is operated at the operation set time to remove ice from the vehicle before boarding, The temperature can be adjusted to the temperature desired by the user.

The ECU 100 operates the smart heating device of the vehicle only when the starting condition is satisfied. The starting condition includes the gear sensing portion 10, the key sensing portion 20, the outside air temperature sensor 30, and the rainwater sensor 40). ≪ / RTI >

That is, the ECU 100 determines that the gear state input from the gear sensing unit 10 is P stage, the key state input from the key sensing unit 20 is off, and the outdoor air temperature input from the outdoor air temperature sensor 30 is zero And when the degree of the rainwater received from the rainwater sensor 40 is equal to or greater than a predetermined value, it is determined that the starting condition is satisfied. Here, the predetermined value for determining the degree of rainwater is a value that can be stored in advance in the storage unit 60 and is determined to be the amount of rainwater enough to cause freezing.

When the start condition is satisfied, the ECU 100 starts up and receives the engine temperature from the engine temperature sensor 50. [ The ECU 100 operates at least one of the heater 80 and the heat line 90 when the engine temperature gauge is above a certain reference, for example, when the temperature gauge is 1/4 or higher.

That is, when the engine temperature becomes a sufficient temperature for operating at least one of the heater 80 and the heat line 90, the ECU 100 can operate at least one of the heater 80 and the heat line 90 have.

Then, the ECU 100 activates at least one of the heater 80 and the heating wire 90, and then, when the internal temperature of the vehicle reaches the internal set temperature, the startup is terminated. Here, the internal set temperature can be preset by the user through the user interface.

At this time, when the ECU 100 is started for a long period of time after the start of the engine, the ECU 100 may set an operation stop time and store it in the storage unit 60 to prevent excessive use of fuel.

As described above, the smart heating device of a vehicle according to an embodiment of the present invention automatically removes freezing by operating a heater and a hot wire according to a heating condition at a set time, thereby shortening the time for freezing, There is an increasing effect.

The smart heating device of the vehicle according to an embodiment of the present invention automatically adjusts the internal temperature of the vehicle to the temperature set by the driver by operating the heater and the heating wire automatically according to the heating condition at the set time, There is an effect to plan.

FIG. 2 is a flowchart illustrating an operation flow for explaining a method of controlling a smart heating device of a vehicle according to an embodiment of the present invention. Referring to FIG. 2, a method of controlling a smart heating device of a vehicle will be described below.

As shown in Fig. 2, the ECU 100 receives an operation selection signal from the operation switch 70 (S100). The operation switch 70 is a switch operated by a user, and on / off of the smart heating device can be controlled in accordance with an operation signal of the operation switch 70.

Therefore, when no operation signal is inputted from the operation switch 70, the operation of the smart heating device of the vehicle is terminated.

If an operation signal is input from the operation switch 70 in step S100, the ECU 100 determines whether the current time is the operation setting time (S200). For example, if the user intends to board the vehicle at 7 o'clock and sets the operation setting time at 6:50 in advance, the smart heating device of the vehicle is operated at the operation set time to remove ice from the vehicle before boarding, The temperature can be adjusted to the temperature desired by the user.

At this time, if the current time is not the operation set time (NO in S200), the current time is continuously grasped to check whether the current time is the operation set time.

On the other hand, if the current time is the operation set time, the ECU 100 determines whether the start condition is satisfied (S300).

Here, the starting condition can be determined based on the gear sensing unit 10, the key sensing unit 20, the outside air temperature sensor 30, and the rainwater sensing sensor 40.

That is, the ECU 100 determines that the gear state input from the gear sensing unit 10 is P stage, the key state input from the key sensing unit 20 is off, and the outdoor air temperature input from the outdoor air temperature sensor 30 is zero And when the degree of the rainwater received from the rainwater sensor 40 is equal to or greater than a predetermined value, it is determined that the starting condition is satisfied.

At this time, if the ECU 100 determines in S300 that the starting condition is not satisfied, the operation of the smart heating device of the vehicle is terminated.

If it is determined in step S300 that the starting condition is satisfied, the ECU 100 turns on the power (S400).

Next, the ECU 100 determines whether the engine temperature sensed by the engine temperature sensor 50 is equal to or higher than a preset reference (S500). At this time, if the engine temperature is lower than the preset reference value (NO in step S500), the engine temperature is continuously monitored.

 On the other hand, the ECU 100 operates at least one of the heater 80 and the heat line 90 when the engine temperature gauge is higher than a certain reference, for example, when the temperature gauge is at 1/4 or higher.

That is, when the engine temperature becomes a sufficient temperature for operating at least one of the heater 80 and the heat line 90, the ECU 100 can operate at least one of the heater 80 and the heat line 90 have.

Accordingly, if the engine temperature is equal to or higher than the preset reference temperature in step S500, at least one of the heater 80 and the heating wire 90 is operated (S600).

After the step S600, the ECU 100 determines whether the internal temperature of the vehicle has reached the internal set temperature (S700). At this time, when the internal temperature of the vehicle has reached the internal set temperature (NO in step S700), the start of the vehicle is terminated (S900).

Here, the internal set temperature can be directly set by the user through the user interface. That is, when the user reaches a desired temperature, the operation of the smart heating device of the vehicle is terminated.

On the other hand, if the internal temperature of the vehicle has not reached the internal preset temperature, the ECU 100 determines whether the operation stop time has elapsed since turning on the vehicle (S800). At this time, if the operation stop time has not elapsed, the flow returns to step S700 to determine whether the internal temperature of the vehicle has reached the internal set temperature (S700).

Here, the operation stop time can be stored in advance in the storage unit 60, and refers to a predetermined time that is used as a criterion for preventing excessive use of fuel when the engine is driven for a long time after turning on the engine.

If the operation stop time elapses in step S800, the ECU 100 stops the start of the vehicle (S900).

As described above, in the method of controlling a smart heating device for a vehicle according to an embodiment of the present invention, the freezing time is shortened by automatically removing heat by operating a heater and a hot wire according to a heating condition at a set time The user convenience is increased.

The method of controlling a smart heating device of a vehicle according to an embodiment of the present invention automatically adjusts an internal temperature of the vehicle to a temperature set by a driver by operating a heater and a hot line automatically according to a heating condition at a predetermined time, There is an effect of promoting comfort.
