Abstract

The present disclosure relates to a power seat integrated control method. One embodiment of the present disclosure includes: a signal input step of receiving a power seat operation signal input that a user inputs through an interface of a vehicle; a determination step of determining an operating condition for operating a motor module that is built into the power seat and moves a specific area of the power seat; and an information transmission step of transmitting driving information for controlling the motor module in accordance with a type of the operation signal. The motor module includes a driving motor and a motor controller which controls the driving motor, and one LIN communication bus is provided between the integrated controller and each power seat. In the information transmission step, the integrated controller transmits the driving information to the motor controller through the LIN communication bus.

First claim

What is claimed is:

1 . A power seat integrated control method which is performed by one integrated controller connected to a plurality of power seats, the method comprising:
a signal input step of receiving a power seat operation signal input that a user inputs through an interface of a vehicle; a determination step of determining an operating condition for operating a motor module that is built into the power seat and moves a specific area of the power seat; and an information transmission step of transmitting driving information for controlling the motor module in accordance with a type of the operation signal, wherein the motor module comprises a driving motor and a motor controller which controls the driving motor, and one LIN communication bus is provided between the integrated controller and each power seat, and wherein, in the information transmission step, the integrated controller transmits the driving information to the motor controller through the LIN communication bus.

2 . The power seat integrated control method according to claim 1 , wherein the determination step comprises:
a step of determining an external condition related to an operation of the power seat 100 ; a step of determining a control target driving motor on the basis of the operation signal; and a step of receiving an error state signal of the control target driving motor from the motor controller and determining whether the control target driving motor is driven or not.

3 . The power seat integrated control method according to claim 2 ,
wherein the step of determining an external condition determines whether an operating power condition, a starting condition, and a driving condition are all satisfied, determines that the operating power condition is satisfied when the integrated controller satisfies a minimum voltage for operating the power seat, determines that the starting condition is satisfied when both an IGN 1 signal and an IGN 2 signal of the vehicle are in an on-state or in an off-state or when the IGN 1 signal is in an off-state and the IGN 2 signal is in an on-state, and determines that the driving condition is satisfied when the vehicle is traveling at a speed less than a predetermined speed.

4 . The power seat integrated control method according to claim 2 ,
wherein the step of determining whether the control target driving motor is drivable or not determines that it is impossible to operate the control target driving motor when the error state signal input from the motor controller of the control target driving motor is at least one of a Hall sensor error signal which represents a state where a Hall sensor signal is not input to the motor controller, an interference error signal which represents a state where the driving motor is no longer able to operate due to an interference with an external object while the control target driving motor operates, and an overcurrent error signal which represents a state an overcurrent flows through the control target driving motor, and further determines a possibility of occurrence of physical interference between a power seat not to be controlled and the power seat to be controlled, on the basis of the Hall sensor signals input from the motor controller of the control target driving motor and the motor controller of a driving motor not to be controlled, and thus, determines whether the control target driving motor is drivable or not.

5 . The power seat integrated control method according to claim 1 ,
wherein, when the operation signal is a manual operation signal for allowing a user to move directly the power seat to a position that the user desires, the information transmission step is to check a driving direction of the power seat input through the interface and transmit driving information corresponding to the driving direction and a manual operation driving speed predetermined in the integrated controller to the motor controller of a control target driving motor, and wherein, when the operation signal is an automatic operation signal for moving the power seat to a pre-stored target position, the information transmission step is to check driving information corresponding to an automatic operation driving speed predetermined in the integrated controller and a hall count value corresponding to the pre-stored target position and transmit the hall count value and the driving information to the motor controller of the control target driving motor.

6 . The power seat integrated control method according to claim 5 , wherein, when the operation signal is the automatic operation signal for moving the power seat to the pre-stored target position, the information transmission step is to determine from the motor controller of the control target driving motor whether motor calibration which learns a distance that the power seat is able to move to the maximum forward and backward is completed or not.

7 . The power seat integrated control method according to claim 1 , further comprising a step of receiving operation state information of the driving motor from the motor controller before the signal input step, wherein the operation state information comprises an error state signal which represents whether the driving motor is drivable or not, a Hall sensor signal which represents current position information of the driving motor, and an operation direction signal which comprises information on an immediately preceding operation direction of the driving motor.
