It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1 is a schematic flow diagram of a control method for electrically unlocking a seat according to an embodiment of the present invention, and the technical solution of the embodiment may be applied to a scene in which the electrically unlocked seat needs to be controlled, and may be executed by the control device for electrically unlocking a seat according to the embodiment of the present invention, and the device may be implemented in a software and/or hardware manner. As shown in fig. 1, the control method includes:
and S110, when the motor is in a driving state, acquiring the running parameters of the motor.
Specifically, the motor is set to be in a driving state, namely when a user needs to control the electric unlocking seat to rotate, a corresponding driving signal is output to the motor in the electric unlocking seat to drive the motor to rotate, the motor in the electric unlocking seat rotates to drive a mechanical structure in the electric unlocking seat to rotate, and when the motor is in the driving state, namely when the motor is electrified with a driving current, the operation parameters of the motor are obtained.
For example, the acquired operation parameter of the motor may be a real-time operation position of the motor, a real-time operation current of the motor, or a real-time operation position of the motor and a real-time operation current of the motor. The real-time operation position of the motor can be the position of a rotor in the motor, and the real-time operation current of the motor can be the driving current which is led into the motor in real time.
S120, acquiring a locked rotor position of the motor according to the acquired running parameters of the motor; the locked-rotor position of the motor corresponds to a hard gear point of the electric unlocking seat.
Specifically, when the motor is in the locked-rotor position, the motor is in a stop rotating state, and when the electric unlocking seat is in the unlocking mode, the locked-rotor position of the motor corresponds to a hard gear point of the electric unlocking seat, that is, when the motor rotates to the locked-rotor position, the motor in the electric unlocking seat drives a mechanical structure in the electric unlocking seat to impact the hard gear point.
For example, the obtained operation parameter of the motor may be a real-time operation position of the motor, and when the real-time operation position of the motor is not changed, since the motor is still in a driving state, it may be determined that the motor is currently in a locked-rotor state, and then the current real-time operation position of the motor may be obtained as the locked-rotor position of the motor. For example, the obtained operation parameter of the motor may also be a real-time operation current of the motor, and when the real-time operation current of the motor is greater than or equal to a locked-rotor current of the motor, it may be determined that the motor is currently in a locked-rotor state, and then the current real-time operation position of the motor may be obtained as the locked-rotor position of the motor.

Alternatively, the rotation stroke of the motor can be divided into a plurality of segmented strokes according to the locked-rotor position of the motor, and the segmented operation of the motor to the electronic gear position of the motor is controlled according to the segmented strokes. Specifically, a rotation stroke of the motor from an initial position to a locked position is divided into a plurality of segmented strokes, then the motor is controlled to run to the position of an electronic gear of the motor in a segmented mode according to the segmented strokes, for example, the rotation stroke of the motor from the initial position to the locked position can be divided into N segmented strokes, then the motor can be controlled to run to N-1 segmented strokes to reach the position of the electronic gear of the motor, the motor can directly rotate to the locked position relative to the control motor, the problem that the unlocking device is driven by the motor to frequently impact a hard gear of a mechanical structure in the unlocking or locking process of the electric unlocking seat can be effectively avoided, the problem that the motor in the electric unlocking seat enters self-protection due to excessive heat productivity is further avoided, the electric unlocking seat can be stably unlocked or locked, and the stability and the safety of the unlocking or locking process of the electric unlocking seat are improved, the user experience is optimized.
Alternatively, the motor may be a direct current motor, the direct current motor may be a direct current motor with a hall element, the number of locked rotor hall pulses of the motor corresponding to the locked rotor position may be obtained, the number of electronic gear hall pulses corresponding to the electronic gear position may be obtained according to the number of locked rotor hall pulses, the number of electronic gear hall pulses is smaller than the number of locked rotor hall pulses, and the motor is controlled to operate to the electronic gear position of the motor according to the number of electronic gear hall pulses. Specifically, the number of locked-rotor Hall pulses of the motor corresponding to the locked-rotor position is the number of Hall pulses corresponding to the rotation of the motor from the initial position to the locked-rotor position, the number of the Hall pulses of the electronic gear corresponding to the position of the electronic gear is the number of the Hall pulses corresponding to the position from the initial position to the position of the electronic gear, the motor is controlled to rotate according to the number of the Hall pulses of the electronic gear which is less than the number of the locked-rotor Hall pulses, so that the motor runs to the position of the electronic gear, the problem that the unlocking device is driven by the motor to frequently impact the hard gear of the mechanical structure in the unlocking or locking process of the electric unlocking seat can be effectively avoided, and then avoid the motor in the electronic unblock seat to get into the problem of self preservation protection because of calorific capacity is too big for electronic unblock seat can stabilize unblock or lock, promotes the stability and the security of electronic unblock seat unblock or lock process, optimizes user's use and experiences.
