Description

TECHNICAL FIELD [0001] The present invention relates to a heating seat system for a vehicle,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to a hot-wire sheet system for a vehicle and a control method thereof, which can save energy for operation of a hot-wire sheet of a vehicle to improve fuel economy of an electric vehicle.

In accordance with global environmental regulations, automakers in each country are researching and developing EV (Electric Vehicle) or PHEV (Plug-in Hybrid Electric Vehicle) that uses electric energy as a main power source. However, due to the battery capacity problem, the power consumption of electrical and electronic parts in automobiles is becoming a big problem because the mileage is relatively short during one charge. Therefore, a heater controller of a hybrid concept is required to reduce the mileage by lowering the power consumption of the hot-wire mat while providing the same satisfaction to passengers.

Conventional hot-wire mat is applied with only one type of hot wire. In this case, in order to lower the power consumption in the power consumption and the calorific power, there is a trade-off problem such that the calorific power is insufficient, and relatively high power consumption is required in order to reach the target temperature satisfying the consumer. These hot-wire mats are now being applied to EVs or PHEVs, which is suffering from a reduction in mileage. In addition, materials with high calorific value relative to power consumption have a problem of cost increase due to relatively high costs.

Therefore, we intend to reduce costs by reducing the average power by using two or more materials in combination, and by reducing the amount of high-priced materials with high calorific value compared to power consumption in cost problems. In addition, we will increase or decrease the passenger satisfaction by utilizing the rapid rise in temperature based on high calorific value.

It should be understood that the foregoing description of the background art is merely for the purpose of promoting an understanding of the background of the present invention and is not to be construed as an admission that the prior art is known to those skilled in the art.

It is an object of the present invention to provide a hot-wire sheet system for a vehicle and a control method thereof that can save energy for operation of a hot-wire sheet of a vehicle to improve fuel efficiency of an electric vehicle and the like.

According to an aspect of the present invention, there is provided a hot-wire sheet system for a vehicle, including: a first heat-generating line and a second heat-generating line embedded in a seat of a vehicle and controlled to generate heat; A temperature sensor for measuring the sheet temperature; And a control unit for operating both the first heating line and the second heating line at the start of heating and for turning off the first heating line and maintaining the set temperature when the measured value of the temperature sensor reaches the set temperature .

The lengths of the heat lines may be different between the first heating line and the second heating line.

The first heating line and the second heating line may have different heat ray materials.

The control unit can control both the first heating line and the second heating line by controlling both the first heating line and the second heating line when the first heating line is off and the second heating line is not controlled.

A control method of controlling a hot-wire sheet system of a vehicle includes a starting step of operating both the first heating line and the second heating line at the start of heating; A first measuring step of measuring a sheet temperature; An off step of turning off the first heat line when the sheet temperature has reached the set temperature; And a holding step of controlling the second heat line so that the sheet temperature maintains the set temperature.

And after the maintaining step, if the sheet temperature does not reach the set temperature, the first heating line is operated again together with the second heating line.

According to the hot-wire sheet system of the vehicle having the above-described structure, the average electric power is reduced by using two or more materials in combination, and the cost is reduced by reducing the amount of expensive material having a high heat- . In addition, it is possible to increase passenger satisfaction by utilizing the rapid temperature rise characteristic based on a high calorific value.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a configuration diagram of a hot-wire sheet system of a vehicle according to an embodiment of the present invention; FIG.
2 is a flowchart of a method of controlling a hot-wire sheet system of a vehicle according to an embodiment of the present invention.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

A heat ray seat system for a vehicle according to the present invention includes a first heat ray (200) and a second heat ray (300) embedded in a seat of a vehicle and controlled for heat generation; A temperature sensor for measuring the sheet temperature; And the first heating line 200 and the second heating line 300 are all operated at the start of heating, and when the temperature sensor measurement value reaches the set temperature, the first heating line 200 is turned off and the second heating line 300 is turned off And a control unit 100 for controlling the temperature to maintain the set temperature.

The present invention reduces costs by reducing the average power by using two or more materials in combination and reducing the amount of expensive materials having a high heating value relative to the power consumption amount even in the case of a cost problem and also achieves a rapid temperature rise characteristic based on a high calorific value To improve passenger satisfaction.

The present invention incorporates two hot wires in the sheet. That is, the first heating line 200 and the second heating line 300, which are embedded in the seat of the vehicle and controlled to generate heat, are provided. The first heating line 200 and the second heating line 300 may have different heating lines or the first heating line 200 and the second heating line 300 may have different heating lines. Therefore, it is preferable that the two heating lines represent different heating values even when the same current is applied. Alternatively, it is also possible to constitute the same hot line and control the current differently, or apply the same common hot line, and separate only on / off control.

On the other hand, the seat is provided with a temperature sensor for measuring the temperature of the seating surface, and a switch for receiving user's control is provided separately. This allows input and setting of the set temperature.

In addition, the control unit 100 operates both the first heating line 200 and the second heating line 300 at the start of heating to increase the quickness. Normally, the hot wire function is used in cold winter. In order to solve the cold quickly at the initial start, the hot wire is operated in a pool to obtain a rapid temperature rise.

 Then, when the measured value of the temperature sensor reaches the preset temperature, the first heating line 200 is turned off and the second heating line 300 is controlled to maintain the set temperature. That is, by turning off the first heating line 200, the leakage current is saved, and only the second heating line 300 is controlled to be turned on and off so that the set temperature is maintained. This makes it possible to reduce fuel consumption in electric vehicles and the like. Alternatively, in the case of the second heat line 300, it is also possible to control the temperature by controlling the current. This can be implemented by turning off the first switch 220 and turning on and off the second switch 320.

On the other hand, when the first heating line 200 is turned off and the second heating line 300 is not controlled, the controller 100 operates both the first heating line 200 and the second heating line 300 Can be controlled. That is, if the capacity of the second heat line 300 is small or the set temperature is very high when the first heat line 200 is turned off by reaching the set temperature, it may be difficult to cope with only the capacity of the second heat line 300 . Therefore, in this case, when the set temperature can not be met by the second heating line 300 alone, the first heating line 200 and the second heating line 300 can be operated again. This is because securing the function of the product itself is more important than fuel economy.

2 is a flowchart of a control method of controlling a hot-wire sheet system of such a vehicle. The control method includes a start step S100 for operating both the first heating line 200 and the second heating line 300 at the start of heating, ; A first measuring step of measuring a sheet temperature; Off step (S200, S300) of turning off the first heating line (200) when the sheet temperature has reached the set temperature; And a holding step (S300) of controlling the second heat line (300) so that the sheet temperature maintains the set temperature. In addition, after the maintaining step, if the sheet temperature does not reach the set temperature, a re-operation step (S400, S500) of operating the first heating line 200 together with the second heating line 300 may be further performed.

That is, initially, both the first heating line 200 and the second heating line 300 are operated to rapidly raise the temperature, and then the first heating line 200 is turned off to conserve energy. If the performance is not sufficient The first heating line 200 and the second heating line 300 are operated together so as to match the performance.

According to the hot-wire sheet system of the vehicle having the above-described structure, the average electric power is reduced by using two or more materials in combination, and the cost is reduced by reducing the amount of expensive material having a high heat- . In addition, it is possible to increase passenger satisfaction by utilizing the rapid temperature rise characteristic based on a high calorific value.

While the present invention has been particularly shown and described with reference to specific embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the following claims It will be apparent to those of ordinary skill in the art.
