It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The application provides a seat position management method, a seat position management device, an in-vehicle device, and a storage medium. In one embodiment, the seat position management method is configured as a complete vehicle production line, and the seat position management apparatus, the in-vehicle apparatus, and the storage medium are all configured for production and adjustment of a vehicle seat.
Referring to fig. 1, fig. 1 is a schematic flow chart illustrating a seat position management method according to an embodiment of the present application. The order of the steps in the flow chart may be changed and some steps may be omitted according to different needs. For convenience of explanation, only portions related to the embodiments of the present application are shown.
According to the seat position management method provided by the embodiment of the application, the seat is driven by the driving unit, and the driving unit comprises the first motor. The seat position management method includes:
and step S1, determining the first position of the seat when the first motor is powered on and started.
Specifically, the first motor and the seat are mounted on the vehicle, and the position of the seat is the first position when the first motor is powered on and started for the first time. It is to be understood that the first position may be any position of the movable range of the seat due to the operation habits of the production line equipment and the worker.
And step S2, determining a first moving direction of the seat driven by the first motor.
In one embodiment, the first motor rotates and drives the seat to move linearly through the linkage mechanism, for example, to adjust the front, back, left and right positions of the seat.
It is understood that the moving direction includes the direction in which the first motor drives the seat to move in forward and reverse directions, and includes two opposite directions, which may be on the same straight line, such as forward and backward, left and right, up and down, and so on.
And step S3, constructing a relative position coordinate system according to the first position and the first moving direction.
In one embodiment, the origin of coordinates of the relative position coordinate system is determined according to the first position, and the direction of one of the coordinate axes of the relative position coordinate system is determined according to the moving direction of the seat. Specifically, the origin of coordinates of the relative position coordinate system may be the first position or another position determined according to the first position, one coordinate axis direction of the relative position coordinate system may be parallel to the moving direction of the seat, for example, the moving direction may be the X-axis direction, and then the Y-axis direction or the Z-axis direction is determined in sequence after the X-axis direction is determined.
In one embodiment, the relative position coordinate system is a two-dimensional coordinate system, e.g., the seat can only move back and forth and side to side. It will be appreciated that in other embodiments the relative position coordinates are three dimensional coordinates, for example the seat may be moved up and down, front to back and left to right.
And step S4, controlling the first motor to drive the seat to move, and acquiring the relative position coordinate of the seat according to the relative position coordinate system.
Therefore, the coordinate origin of the relative position coordinate system is determined according to the position when the motor is powered on and started, and the direction of the coordinate axis of the relative position coordinate system is determined according to the moving direction of the seat, so that the relative position coordinate system is quickly constructed, and the position of the seat is managed.

Referring to fig. 2, in an embodiment, the seat position management method further includes:
and step S11, determining that the first locked rotor of the first motor occurs.
Specifically, whether the motor is locked up or not is detected, whether the current of the motor is larger than a current threshold value or not can be detected, and the locked up of the motor is determined when the current of the motor is larger than the current threshold value. For example, the operating current of motor is 16A, and when the motor moved to the locked-rotor position, because the seat structure was spacing, caused the motor to stop hard, the electric current was locked-rotor current this moment, and locked-rotor current was about 25A, so the accessible detected current whether to take place locked-rotor with the detection motor.
In another embodiment, the first motor includes a hall sensor, and it is determined whether stalling of the first motor occurs based on hall pulses generated by the hall sensor of the first motor. Specifically, whether a Hall pulse generated by a Hall sensor of the first motor is identified within a preset first time is judged, if yes, it is determined that the first motor is not locked, and if not, it is determined that the first motor is locked.
The first locked rotor may be a first locked rotor actually occurring or a first locked rotor actually measured by the first motor.
And step S12, determining a second position of the seat when the first motor is locked for the first time.
In particular, the second position may comprise relative position coordinates of the seat.
Step S13, an absolute position coordinate system is constructed according to the second position and the first moving direction.
Specifically, the origin of coordinates of the absolute position coordinate system may be determined based on the second position, and the directions of the coordinate axes of the absolute position coordinate system may be determined based on the first moving direction, for example, the second position may be set as the origin of coordinates of the absolute position coordinate system, and the directions of one coordinate axis of the absolute position coordinate system may be parallel to the first moving direction.
Thus, when the user uses the seat, the relative coordinate system can be switched to the absolute coordinate system; therefore, the time consumed in the whole automobile production process is avoided for calibrating the absolute coordinate system of the seat.
In another embodiment, the seat position management method further includes the steps of:
and step S14, determining a third position of the seat when the first motor is in reverse direction locked rotation.
Specifically, the first motor drives the seat to move in two opposite directions by forward rotation and reverse rotation, respectively. The rotation direction of the first motor is different from that of the first motor in the previous locked rotor process through detection, and the position of the seat in the locked rotor process is obtained, wherein the rotation direction of the first motor in the locked rotor process in the opposite direction is opposite to that of the first motor in the locked rotor process for the first time, for example, the first motor rotates positively when the locked rotor process is performed for the first time, and the first motor rotates reversely when the locked rotor process is performed in the opposite direction.
And step S15, acquiring a first stroke length of the seat according to the second position and the third position.
Specifically, the limit position of the seat moving along the first moving direction is determined through the locked rotation of the first motor in the positive and negative directions, and the maximum distance of the seat moving along the moving direction is determined through the two limit positions, namely the first stroke length.
And step S16, adjusting the absolute coordinate origin of the absolute position coordinate system according to the first stroke length.
So, can rotate and take place twice stifled commentaries on classics through first motor positive and negative direction when the user uses the seat, judge the displaceable distance of first motor drive seat according to twice stifled commentaries on classics, first stroke length promptly, through the initial point of displaceable distance adjustment absolute coordinate system to promote the accuracy of absolute coordinate initial point.

In an embodiment, the seat position management method further comprises: and determining the corresponding relation between the absolute position coordinate system and the relative position coordinate system according to the first position and the second position.
For example, the relative position coordinate system is a two-dimensional coordinate system, the relative coordinate of the first position is (0, 0), the relative coordinate of the second position is (3, 0), and 3 is added to the number of the X-axis of the relative coordinate of the seat, so as to obtain the absolute coordinate of the seat, so as to realize the conversion of the position of the seat between the two coordinate systems.
In an embodiment, the drive unit further comprises a second motor, the method further comprising:
determining that two times of locked rotations occur when the second motor drives the seat to move along a second moving direction, wherein the first moving direction is vertical to the second moving direction, and the rotating directions of the second motor are opposite when the two times of locked rotations occur;
determining that the seat is respectively in a fourth position and a fifth position when the second motor is locked;
acquiring a second stroke length of the seat according to the fourth position and the fifth position;
and adjusting the absolute coordinate origin of the absolute position coordinate system according to the second stroke length.
Specifically, the second motor drives the seat to move by forward rotation and reverse rotation, and the movable length in the second movement direction is acquired by the second motor being locked, for example, the movable length in the X-axis direction may be determined by the first motor, and the movable length of the seat in the Y-axis direction may be determined by the second motor being locked. The absolute coordinate origin can be adjusted through the first stroke length or the second stroke length so as to improve the accuracy of the absolute coordinate origin.
In one embodiment, the adjusting the absolute coordinate origin of the absolute position coordinate system according to the second stroke length includes:
determining a first coordinate of a first midpoint of the first stroke length;
determining a second coordinate of a second midpoint of the second stroke length;
and determining the absolute coordinate origin according to the first coordinate and the second coordinate.
In this way, the absolute coordinate origin is determined by the two strokes in the two coordinate directions, so that the absolute coordinate origin and the actual coordinate origin of the seat are ensured to be located at the same position.
