[0046] Embodiment one

[0047] Figure 1 Fig. 1 is a flow chart of a method for preventing a seat from being clamped according to an embodiment of the present application. The embodiment can be applied to a situation where an electric seat is adjusted. The method can be performed by a seat clamping prevention control device of the electric seat. The seat clamping prevention control device can be implemented in the form of hardware and / or software. The seat clamping prevention control device can be configured in an electronic device having data processing capability. As shown in Fig. 1, the method comprises the following steps. Figure 1

[0048] The technical solution of the embodiment can be applied to an electric seat of a vehicle. When the electric seat is moving, whether the electric seat is clamped can be determined based on a received pulse signal, so that a user sitting on the electric seat can be prevented from being clamped or the electric seat can be prevented from being blocked.

[0049] S110, obtaining an initial pulse signal of the electric seat when it is detected that the electric seat is moving.

[0050] The electric seat can be an electric seat of a vehicle. The initial pulse signal can be a pulse signal with the same pulse width. The initial pulse signal can be understood as a pulse signal of the electric seat when it is moving at a constant speed after being started for a period of time. The pulse signal in the embodiment can be a Hall pulse signal emitted by a Hall sensor in the electric seat. The electric seat moving can be understood as the electric seat running on a running track. The electric seat moving in the embodiment can be the electric seat moving when a driver adjusts the seat.

[0051] For example, an example diagram of the initial pulse signal in the embodiment is shown in Fig. 2. After the electric seat is started for a period of time, the movement of the electric seat reaches a balanced state. At this time, it can be considered that the electric seat is moving at a constant speed. The rising edge of the third pulse after starting to the falling edge can be regarded as the initial pulse signal T0. Figure 2

[0052] S120, when the pulse width of the initial pulse signal meets a first set condition, regarding the initial pulse signal meeting the first set condition as a target pulse signal.

[0053] The first set condition can be understood as a condition that is set in advance for the size of the pulse width of the pulse signal. The first set condition in the embodiment can be that the width of the pulse signal is gradually increasing. The target pulse signal can be understood as a pulse signal whose pulse width is increasing.

[0054] ​​In the embodiment, optionally, when the pulse width of the initial pulse signal meets the first set condition, the initial pulse signal meeting the first set condition is taken as the target pulse signal, including: when the pulse width of the initial pulse signal continuously increases, the pulse signal with continuously increasing pulse width is taken as the target pulse signal.

[0055] In the embodiment, when the pulse width of the initial pulse signal continuously increases, the pulse signal with continuously increasing pulse width is taken as the target pulse signal. When the pulse width of the initial pulse signal changes in the embodiment, the electric seat may be in a clamping state or a locked state at this time. In the embodiment, the initial pulse signal with increasing pulse width is taken as the target pulse signal through the setting, so as to facilitate subsequent judgment operation.

[0056] S130, judging whether the target pulse signal meets the second set condition.

[0057] The second set condition can be understood as a pre-set condition, and can be used to judge whether the target pulse signal is in a clamping state. In the embodiment, whether the target pulse signal meets the pre-set second set condition can be judged.

[0058] In the embodiment, optionally, whether the initial pulse signal and the target pulse signal meet the second set condition is judged, including: judging whether the target pulse signal is greater than or equal to the first set pulse signal threshold and the target pulse signal continuously increases.

[0059] The first set pulse signal threshold is determined by the initial pulse signal and the first set pulse signal. The first set pulse threshold can be a pre-set pulse threshold. The first set pulse signal can be understood as a pulse signal fed back after the set anti-pinch force constant value is converted into speed, and can be set according to actual needs. For example, the example graph of the first set pulse signal in the embodiment can be as shown in FIG. 1, and the set anti-pinch force constant value can be converted into a Hall pulse waveform with a duty cycle of 50% and a rising edge to falling edge set as the first set pulse signal ΔT. Figure 3

[0060] In the embodiment, the first set pulse signal threshold can be determined by the initial pulse signal and the first set pulse signal. Specifically, the first set pulse signal threshold in the embodiment can be the sum of the initial pulse signal and the first pulse signal. In the embodiment, whether the target pulse signal is greater than or equal to the sum of the initial pulse signal and the first pulse signal and the target pulse signal continuously increases is judged, so as to judge whether the current electric seat is in a clamping state.

[0061] ​In the embodiment, by setting the conditions, whether the target pulse signal meets the set conditions is determined, and whether the electric seat is in the clamped state is determined, the influence of seat consistency and passenger weight is avoided, and the accuracy of determining the electric seat is improved.

[0062] In S140, if the target pulse signal meets the second set condition, the movement of the electric seat is limited.

[0063] In the embodiment, if it is determined that the target pulse signal is greater than or equal to the first set pulse signal threshold and the target pulse signal is continuously increasing, it indicates that the electric seat is in the clamped state, and the current movement operation of the electric seat needs to be limited to achieve the purpose of anti-pinch.

[0064] For example, the target pulse signal in the clamped process in the embodiment is shown in the example diagram as shown in the figure. Figure 4 In the clamped process, the clamping force is increasing until it is unchanged after balancing, and the speed is decreasing until it stops, which is reflected in the pulse that the pulse width is gradually increasing until the pulse does not jump in a period of time. When the pulse width of the target pulse signal starts to change and becomes a continuously increasing target pulse signal, the rising edge to the falling edge time period T1 and T1>T0; the falling edge to the rising edge time period T2 and T2>T1; the rising edge to the falling edge time period T3 and T3>T2; then when the pulse signal T3≥T0+△T, and T3>T2, and T2>T1, and T1>T0, it indicates that the electric seat is in the clamped state; or when T2≥T0+△T; and T2>T1, and T1>T0, it also indicates that the electric seat is in the clamped state, and then the movement of the electric seat needs to be exited. Wherein, T0 is the initial pulse signal, and △T can be the first set pulse signal.

[0065] In the embodiment, optionally, the method further includes: determining whether the target pulse signal meets the third set condition; if the target pulse signal meets the third set condition, the current is in the locked-rotor state.

[0066] The third set condition can be understood as a pre-set condition, which can be used to determine whether the target pulse signal is in the locked-rotor state. The locked-rotor state can be understood as a state in which the current electric seat slides to the end of the track in the running track. In the embodiment, it is determined that the current electric seat is in the locked-rotor state by determining whether the target pulse signal meets the set condition. In the embodiment, by setting in this way, the locked-rotor state and the clamped state can be distinguished, and the accuracy of determining the clamped state is improved.

[0067] In the embodiment, optionally, whether the target pulse signal meets the third set condition includes: determining whether the target pulse signal is greater than the second set pulse signal threshold.

[0068] The second set pulse signal threshold is determined by the initial pulse signal and the second set pulse signal. The second set pulse threshold can be a preset pulse threshold. The second set pulse signal can be the same as the first set pulse signal.

[0069] The second set pulse signal threshold in the embodiment can be determined by the initial pulse signal and the second set pulse signal. Specifically, the second set pulse signal threshold in the embodiment can be a value of the sum of twice the initial pulse signal and the second pulse signal. In the embodiment, whether the target pulse signal is greater than the value of the sum of twice the initial pulse signal and the second pulse signal can be determined, so as to determine whether the current electric seat is in the stall state; if the target pulse signal is greater than the value of the sum of twice the initial pulse signal and the second pulse signal, it indicates that the current electric seat is in the stall state.

[0070] For example, the target pulse signal in the stall process in the embodiment is shown in the example diagram as shown in Figure 5a In the embodiment, the pulse signal in the stall state can be a lower stop rotation, and the pulse width does not jump in a unit time or a period of time. Specifically, when the pulse width of the initial pulse signal starts to change and becomes the target pulse signal that continuously increases, the time period after the rising edge is T4; or as shown in Figure 5b The pulse width starts to change, and the time period after the falling edge is T5; when T4>T0+2△T or T5>T0+2△T is determined, it is determined that the current target pulse signal is in the stall state. Wherein, T0 is the initial pulse signal, and △T can be the second set pulse signal.

[0071] The technical scheme of the embodiment of the application comprises the following steps: when the movement of the electric seat is detected, the initial pulse signal of the electric seat is acquired; wherein the initial pulse signal is a pulse signal with the same pulse width; when the pulse width of the initial pulse signal meets the first set condition, the initial pulse signal meeting the first set condition is taken as the target pulse signal; whether the target pulse signal meets the second set condition is determined; and if the target pulse signal meets the second set condition, the movement of the electric seat is limited. The technical scheme can solve the problem that the electric vehicle seat is easily affected by seat consistency and passenger weight, so as to reduce the probability of misjudgment.
