[0046] [Table 1]

[0047]

[0048] In Table 1, it was determined that the case of a male with a height of 177cm and a weight of 80kg is the same as that of a female with a height of 156cm and a weight of 44kg, and the same voltage drop rate (5% / minute) can be applied. Furthermore, it was determined that the case of a female with a height of 156cm and a weight of 44kg is the same as that of a female with a height of 150cm and a weight of 45kg, and the same voltage drop rate (5% / minute) can be applied.

[0053] Sensor 20 can acquire position information related to vehicle seat 200. In this case, the position information is the angle of vehicle seat 200 and may include the angle of seat back (θ1) and the angle of seat cushion (θ2).

[0054] The sensor 20 may include a first motor position sensor for detecting the position of a first motor and a second motor position sensor for detecting the position of a second motor, the first motor adjusting the angle of the seat cushion and the second motor adjusting the angle of the seat cushion.

[0055] Sensor 20 may include a temperature sensor that measures the temperature of the vehicle seat 200. In this case, the temperature sensor may be a temperature sensor based on a negative temperature coefficient (NTC) device.

[0056] The controller 30 can perform overall control to ensure that the various components described above perform their functions correctly. The controller 30 can be implemented in hardware or software, or a combination of hardware and software. The controller 30 can be implemented using a microprocessor, but is not limited to this.

[0057] The controller 30 can perform various controls during the following process, which is used to adjust the voltage supplied to the heating wire 210 or the blower 200 disposed in the vehicle seat 200 based on the position of the vehicle seat 200.

[0058] The controller 30 can perform various controls during the following process, which is based on occupant-related physical information and the power consumption of the vehicle seat 200, and adjusts the voltage supplied to electrical devices (e.g., heating wire 210 or blower 220) disposed in the vehicle seat 200.

[0059] The controller 30 can perform various controls based on the position of the vehicle seat 200 and the physical information related to the occupants of the vehicle seat 200, as well as the power consumption of the vehicle seat 200, and the voltage supplied to the heating wire 210 or blower 220 disposed in the vehicle seat 200.

[0060] The controller 30 can access the vehicle network and collect various types of information. In this case, the vehicle network may include a Controller Area Network (CAN), a Controller Area Network with Flexible Data Rate (CAN FD), a Local Interconnect Network (LIN), FlexRay, Media-Oriented System Transport (MOST), and Ethernet, etc.

[0061] In the following text, reference will be made to Figure 2 , Figure 3 ,as well as Figure 4 The operation of controller 30 is described.

[0062] Figure 2 This is an exemplary view illustrating the principle of a vehicle seat power consumption control device according to various exemplary embodiments of the present invention, which reduces battery power consumption while maintaining the occupant's perceived temperature at a certain level.

[0063] refer to Figure 2 It can be seen that the contact area between the seat and the occupant changes with the angle of the seat cushion (θ). b The increase in ) and the change in the angle of the seat back (θ) a The temperature increases with the increase of the contact area. Even if the voltage supplied to the heating wire 210 decreases by a certain level, the amount of heat transfer increases because of the increased contact area, resulting in no significant difference in the occupant's perceived temperature. Similarly, even if the voltage supplied to the blower 220 decreases by a certain level, the amount of air transfer increases because of the increased contact area between the seat and the occupant, resulting in no significant difference in the occupant's perceived temperature. The controller 30 can use this principle to adjust the voltage supplied to the heating wire 210 or the blower 220 according to the position of the vehicle seat 200.

[0064] Figure 3 This is an exemplary view of a graph showing the power consumption of a vehicle seat control device according to various exemplary embodiments of the present invention for controlling power consumption in a vehicle seat.

[0065] like Figure 3 As shown, the horizontal axis represents the angle θ of the vehicle seat at 200 degrees, and the vertical axis represents the perceived temperature (K) and the contact area (m²). 2 () or supply voltage (V). For example... Figure 2 As shown, when the angle θ of the vehicle seat 200 increases (i.e., when the seat back is reclined), the contact angle between the torso line and the seat back increases from θ... a Reduce to θ b This increases the contact area between the vehicle seat 200 and the occupant (310). As the contact area increases as described above, the voltage supplied to the heating wire 210 or the blower 220 decreases (320), thereby maintaining the perceived temperature felt by the occupant (330). In this case, a preheating time is required in the initial stage of operation of the heating wire 210 or the blower 220, so that the voltage supplied to the heating wire 210 or the blower 220 decreases after a certain period of time (e.g., 5 minutes), but it is not necessarily limited to this.

[0066] Figure 4 This is an exemplary view illustrating the processing of the supply voltage based on seat angle adjustment in a vehicle seat power consumption control device according to various exemplary embodiments of the present invention.

[0067] First, the controller 30 can determine the voltage drop rate Kc(410) corresponding to the seat angle θ based on the following [Formula 1].

[0068] [Formula 1]

[0069]

[0070] Here, "B" represents a correction factor based on the thickness of the seat, "θ" represents the seat angle, and "C" represents a correction factor based on the material of the seat. The values ​​used to determine the voltage drop rate of the heating wire 210 and the values ​​used to determine the voltage drop rate of the blower 220 may differ from each other, relative to "B" and "C".

[0071] Subsequently, the controller 30 can obtain the voltage "V" (420) supplied to the heating wire 210 or the blower 220. In this case, the controller 30 can obtain this voltage through the vehicle network.

[0072] The controller 30 can then adjust the voltage "V" supplied to the heating wire 210 or the blower 220 based on the result of multiplying the known voltage "V" by the voltage drop rate. For example, when the supply voltage is 5V and the voltage drop rate is 10%, the controller 30 can change the supply voltage to 4.5V. This is described in more detail with reference to Table 2 below.

[0073] [Table 2]

[0074]

[0075] Table 2 shows the results of reducing the voltage supplied to the heating wire 210 when the seat angle is changed 15° backward from the reference position (θ = 0). It can be seen that the heating level remains constant, and the contact area between the seat and the occupant changes with the seat angle. Therefore, the controller 30 adjusts the supply voltage, and thus, also adjusts the actual temperature. However, it can be seen that the occupant's perceived temperature remains the same.

[0076] Therefore, the controller 30 can reduce the voltage supplied to the heating wire 210 while maintaining the occupant's perceived temperature within tolerance, thereby reducing the amount of power consumed in the battery 300. This means improved fuel efficiency in the vehicle (especially electric vehicles). The following [Table 3] shows the fuel gain rate measured when various exemplary embodiments of the invention are applied to actual vehicles.

[0077] [Table 3]

[0078]

[0079] Meanwhile, as another exemplary embodiment of the present invention, the controller 30 can adjust the voltage supplied to the heating wire 210 or the blower 220 disposed in the vehicle seat 200 based on the table in [Table 1].

[0080] After obtaining physical information related to the occupant (passenger), the controller 30 can determine the voltage drop rate based on the table in [Table 1], and apply the determined voltage drop rate to the voltage supplied to the heating wire 210 or blower 220, taking into account the operating time of the heating wire 210 or blower 220. That is, the controller 30 can adjust the voltage supplied to the heating wire 210 or blower 220 based on the determined voltage drop rate. In this case, the number of times the voltage drop rate is applied can be limited according to the designer's intention.

[0081] In another exemplary embodiment of the invention, the controller 30 may adjust the voltage supplied to the heating wire 210 or the blower 220 disposed in the vehicle seat 200 based on the position of the vehicle seat 200, physical information related to the occupant of the vehicle seat 200, and the power consumption time of the vehicle seat 200.

[0082] That is, the controller 30 can initially apply the voltage drop rate obtained based on [Table 1] to the voltage supplied to the heating wire 210 or the blower 220, and then apply the voltage drop rate obtained based on the position of the vehicle seat 200 to the result of the initial application.

[0083] Figure 5 This is a flowchart of a method for controlling power consumption in a vehicle seat according to various exemplary embodiments of the present invention.

[0084] First, sensor 20 can obtain the angle (501) of vehicle seat 200.

[0085] Subsequently, the controller 30 can adjust the voltage supplied to the electrical equipment (heating wire 210 or blower 220) disposed in the vehicle seat 200 based on the angle of the vehicle seat 200 (502). In this case, the controller 30 can determine the voltage drop rate using the angle of the vehicle seat 200, a correction factor based on the thickness of the vehicle seat 200, and a correction factor based on the material of the vehicle seat 200, and adjust the voltage supplied to the electrical equipment according to the determined voltage drop rate.

[0086] Figure 6 This is a flowchart of a method for controlling power consumption in a vehicle seat according to various exemplary embodiments of the present invention.

[0087] First, the storage device 10 can store a table (601) that records physical information related to the occupants of the vehicle seat 200 and the corresponding voltage drop rate.

[0088] Subsequently, the controller 30 can adjust the voltage supplied to the electrical equipment (heating wire 210 or blower 220) based on the voltage drop rate (602). In this case, the controller 30 can adjust the number of times the voltage drop rate is applied to the voltage supplied to the electrical equipment based on the operating time of the electrical equipment. Furthermore, the controller 30 can initially apply the voltage drop rate obtained according to [Table 1] to the voltage supplied to the electrical equipment, and then apply a voltage drop rate determined based on the vehicle angle to the result of the initial application.
