Description

Battery built-in seat system and control method thereof {Battery built-in seat system and control method thereof}

The present invention relates to a seat system with a built-in battery and a method for controlling the same, and more particularly, power is supplied to the seat independently while the engine is turned off, and the seat is installed in the seat without a separate cooling device by utilizing a seat ventilation blower. It relates to a battery-embedded seat system that efficiently manages the temperature of a battery and a control method therefor.

A vehicle seat refers to a seat provided for an occupant to sit in a vehicle. In general, the seats are arranged so that five people can sit together in a car or SUV, including the driver's seat, the front passenger's seat, and the rear seat. The types of first-row seats are largely classified into separate seats and bench seats. The former is mainly designed for passenger cars in a way that the driver's seat and passenger seat are divided based on the console box. The latter is designed primarily for light trucks in such a way that three people are arranged to sit side by side.

Looking at the detailed configuration of the seat, when a vehicle contact accident occurs, the upper part of the seat that serves as a pillow while preventing the occupant's head from being tilted back and receiving an impact is called a head rest. The armrests on the left and right sides of the seat are called arm rests, and the backrest structure that supports the passengers' backs is called lumber support. In general, in the case of a vehicle seat, it is configured to slide forward or backward according to the physical condition of a passenger or the driver's driving habit. In addition, it is equipped with convenient functions for passengers such as heater and ventilation.

In the conventional vehicle seat, various functions of the seat could be driven only by receiving power directly from a vehicle battery provided inside the vehicle. However, as the mass production of electric vehicles has recently entered, the power of a vehicle battery consumed for functions other than vehicle driving may adversely affect the total driving distance of the vehicle. In addition, in case of a vehicle collision accident, when the vehicle is overturned or the frame constituting the outer shape of the vehicle is deformed and the vehicle door is not opened, and passengers are trapped in the vehicle, the power supplied from the vehicle body is cut off due to damage to the vehicle. Since the seat and vehicle door cannot be controlled, escape is impossible, and rescuers also have difficulty in rescue.

In addition, the conventional vehicle seat has a disadvantage that the seat can be controlled only when the engine of the vehicle is turned on. On the other hand, there are many cases in which a passenger wants to control a seat in a state in which the engine of the vehicle is turned off. For example, when traveling by vehicle, such as camping or parking, the fact that seat functions can be used only after the vehicle is turned on is a great inconvenience to passengers.

In addition, in terms of safety, if only infants or companion animals remain in the vehicle, if the use of the seat heater, ventilation function, and multimedia function is required, the vehicle engine must be turned on. In this state, there is a risk of causing a safety accident.

Therefore, technical development of a battery-embedded seat system designed to independently control the seat regardless of the presence or absence of power directly supplied from the vehicle body and a control method thereof is in progress.

As an example, the battery charging process of the front seat can be looked at. When the current charge amount of the battery installed in the front seat seat is less than a certain amount of the total charge amount (eg, less than 40% of the total charge amount), charging is in progress. When a passenger is seated in a seat, in an emergency charging situation where the seat battery needs to be recharged in a hurry, the seat battery is immediately charged up to a certain amount of the total charge amount (e.g., 60% of the total charge amount), and in non-emergency charging situations , a notification sound notifying the need to recharge the seat battery is generated. When the user inputs the charge switch, the front seat is moved to a charging position provided in the first row of the vehicle, and the seat battery is charged.

Similarly, if a passenger is not seated in a seat, the front seat moves directly to the charging position. When the seat reaches the rearmost point where the seat battery can be charged by sliding movement, the seat battery is charged using the vehicle power on the premise that power is being supplied from the vehicle to the seat. However, in the case of the prior art, the seat battery built into the seat could only be used to supply power for controlling the seat, and it could be charged only when the seat was located at the rear of the first row space of the vehicle according to the sliding movement. existed. Accordingly, when the seat is located in a position where the seat battery cannot be charged inside the vehicle and the seat battery is discharged, an alternative method for controlling the seat is required. In addition, it is necessary to check whether the occupant is seated in order to charge and operate the seat battery, and it is necessary to configure a separate algorithm to check whether the occupant is seated, such as seat belt fastening and SBR mat recognition. existed
