Description

Technical Field

[0001] The present invention belongs to the technical field related to vehicles, and in particular relates to a zero-gravity vehicle seat control method, a control device, a vehicle and a storage medium. Background Art

[0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] The zero-gravity seat achieves zero contact between the occupant's body and the seat surface by adjusting the seat cushion inclination, backrest angle, leg rest extension and flip posture, so that the seat can bear the gravity of various parts of the occupant to the greatest extent, reduce the load on the occupant's bones, and let the occupant feel a different zero-gravity space experience.

[0004] Zero-gravity chairs have anti-accidental clamping problems due to motor failure. The existing solution uses current detection to make anti-accidental clamping judgments, but when the motor is blocked due to an object being clamped, it can only be detected through current, which has a lag. In addition, the zero-gravity chair's accidental clamping is caused by relative position, and only detecting a single position cannot accurately predict whether there is an anti-accidental clamping risk. Summary of the Invention

[0005] To overcome the deficiencies of the above-mentioned prior art, the present invention provides a zero-gravity vehicle seat control method, control device, vehicle and storage medium, which can promptly detect and adjust when a motor fails to prevent accidental clamping and protect the occupants.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions: In a first aspect, the present invention provides a zero-gravity vehicle seat control method, comprising: When the vehicle seat is in zero gravity mode, obtaining a motor pulse number at a first position of the vehicle seat, and calculating an angle corresponding to the currently obtained motor pulse number at the first position of the vehicle seat based on a preset motor pulse number and a corresponding angle at the first position; Obtaining a motor pulse number at a second position of the vehicle seat, and calculating an angle corresponding to the currently obtained motor pulse number at the second position of the vehicle seat based on a preset motor pulse number and a corresponding angle at the second position; wherein the first position and the second position correspond to each other; The angle corresponding to the number of motor pulses at the first position of the vehicle seat is subtracted from the angle corresponding to the number of motor pulses at the second position of the vehicle seat. The subtraction result is compared with the calibrated angle range corresponding to the comfort level to determine whether the vehicle seat has a risk of mis-clamping. If the vehicle seat has a risk of mis-clamping, the action of the motor at the first position and / or the motor at the second position is controlled.

[0007] In some embodiments, the angle corresponding to each pulse number of the motor at the first position is calculated based on the preset pulse number and the corresponding angle of the motor at the first position, and the angle corresponding to the current number of motor pulses at the first position is calculated based on the angle corresponding to each pulse number of the motor at the first position and the currently acquired number of motor pulses at the first position; Or, based on the preset number of pulses and the corresponding angle of the motor at the second position, calculate the angle corresponding to each pulse number of the motor at the second position; based on the angle corresponding to each pulse number of the motor at the second position and the currently obtained number of motor pulses at the second position, calculate the angle corresponding to the current number of motor pulses at the second position.

[0009] In some embodiments, if there is a risk of mis-clamping of the vehicle seat, the motor at the first position and / or the motor at the second position are controlled to operate as follows: If there is a risk of mis-clamping of the vehicle seat, the motor in the first position and / or the motor in the second position are controlled to reverse, so that the number of pulses of the motor in the first position and / or the motor in the second position is reduced until the seat reaches a comfortable angle.

[0010] In some embodiments, during the reversal control process of the motor at the first position and / or the motor at the second position, if the number of pulses of the reversal of the motor at the first position and / or the motor at the second position is zero within a first interval, it is determined that the motor at the first position and / or the motor at the second position is faulty, and the motor at the first position and / or the motor at the second position is turned off.

[0011] In some embodiments, the further step includes: constructing a root cause relationship network of motor pulses, and determining the motor fault type according to the root cause relationship network based on the number of pulses obtained within a set time.

[0012] In some embodiments, the root cause relationship network of the motor pulses is constructed, and the motor fault type is determined according to the number of pulses obtained within a set time. Specifically, the root cause relationship network is: The root cause relationship network of motor pulses is constructed based on the time domain, frequency domain and amplitude characteristics of the motor pulse number as the network input nodes, the hardware status and environmental parameters as the transition nodes, and the fault type as the network output node. Conditional probability is introduced to describe the strength of causal association. According to the number of pulses obtained within the set time, the root cause of the fault is traced back and determined through posterior probability calculation.

[0013] In a second aspect, the present invention provides a zero-gravity vehicle seat control device, comprising: a first calculation module configured to: when the vehicle seat is in the zero-gravity mode, obtain a motor pulse number at a first position of the vehicle seat, and calculate an angle corresponding to the currently obtained motor pulse number at the first position of the vehicle seat based on a preset motor pulse number and a corresponding angle at the first position; a second calculation module configured to: obtain a motor pulse number at a second position of the vehicle seat, and calculate an angle corresponding to the currently obtained motor pulse number at the second position of the vehicle seat based on a preset motor pulse number and a corresponding angle at the second position; wherein the first position and the second position correspond to each other; A control module is configured to: subtract the angle corresponding to the number of motor pulses at the first position of the vehicle seat from the angle corresponding to the number of motor pulses at the second position of the vehicle seat, compare the subtraction result with the calibrated angle range corresponding to the comfort level, determine whether the vehicle seat has a risk of mis-clamping, and if the vehicle seat has a risk of mis-clamping, control the action of the motor at the first position and / or the motor at the second position.

DETAILED DESCRIPTION

[0020] It should be noted that the following detailed descriptions are exemplary and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which the present invention belongs.

[0021] It should be noted that the terms used herein are for describing particular embodiments only and are not intended to limit the exemplary embodiments according to the present invention.

[0022] In the absence of conflict, the embodiments of the present invention and the features thereof may be combined with each other.

[0023] The zero-gravity seat includes an ECU and a seat motor; the ECU is used to detect the pulse number status of the seat motor, and the ECU includes a comparator and a single-chip microcomputer. The seat motor includes a Hall sensor, and the Hall sensor is used to collect the motor pulse voltage; the seat motor includes a backrest motor, a seat cushion motor and a footrest motor. The backrest motor is used to drive the seat back, the seat cushion motor is used to drive the seat cushion, and the footrest motor is used to drive the seat footrest; the seat motors are set to move at a uniform speed.

[0024] like Figure 1 As shown, this embodiment discloses a zero-gravity vehicle seat control method, including: S101: When the vehicle seat is in zero gravity mode, obtaining a motor pulse number at a first position of the vehicle seat, and calculating an angle corresponding to the currently obtained motor pulse number at the first position of the vehicle seat based on a preset motor pulse number and a corresponding angle at the first position; S102: Obtaining a motor pulse count at a second position of the vehicle seat, and calculating an angle corresponding to the currently obtained motor pulse count at the second position of the vehicle seat based on a preset motor pulse count and a corresponding angle at the second position; wherein the first position and the second position correspond to each other; S103: Subtract the angle corresponding to the number of motor pulses at the first position of the vehicle seat from the angle corresponding to the number of motor pulses at the second position of the vehicle seat, and compare the difference result with the calibrated angle range corresponding to the comfort level to determine whether the vehicle seat has a risk of mis-clamping. If the vehicle seat has a risk of mis-clamping, control the action of the motor at the first position and / or the motor at the second position.

[0025] As an implementation method, according to the preset number of pulses of the motor at the first position and the corresponding angle, the angle corresponding to each pulse number of the motor at the first position is calculated; according to the angle corresponding to each pulse number of the motor at the first position and the currently obtained number of motor pulses at the first position, the angle corresponding to the current number of motor pulses at the first position is calculated; Or, based on the preset number of pulses and the corresponding angle of the motor at the second position, calculate the angle corresponding to each pulse number of the motor at the second position; based on the angle corresponding to each pulse number of the motor at the second position and the currently obtained number of motor pulses at the second position, calculate the angle corresponding to the current number of motor pulses at the second position.

[0026] As an implementable method, Figure 2 As shown, the angle corresponding to the number of motor pulses in the first position of the vehicle seat is subtracted from the angle corresponding to the number of motor pulses in the second position of the vehicle seat. The subtraction result is compared with the calibrated angle range corresponding to the comfort level to determine whether the vehicle seat has a risk of mis-clamping. Specifically, S201: If the difference between the angle corresponding to the number of motor pulses at the first position of the vehicle seat and the angle corresponding to the number of motor pulses at the second position of the vehicle seat is less than the minimum value of the calibrated angle range corresponding to the comfort level, it is determined that there is a risk of mis-clamping of the current vehicle seat; S201: When the difference between the angle corresponding to the number of motor pulses at the first position of the vehicle seat and the angle corresponding to the number of motor pulses at the second position of the vehicle seat is greater than the maximum value of the calibrated angle range corresponding to the comfort level, it is determined that the current vehicle seat is uncomfortable.

[0027] As an implementation method, if there is a risk of mis-clamping of the vehicle seat, the motor at the first position and / or the motor at the second position are controlled to operate as follows: If there is a risk of mis-clamping of the vehicle seat, the motor in the first position and / or the motor in the second position are controlled to reverse, so that the number of pulses of the motor in the first position and / or the motor in the second position is reduced until the seat reaches a comfortable angle.

[0028] As an implementable embodiment, during the reversal control process of the motor at the first position and / or the motor at the second position, if within a first interval, the number of pulses of the reversal of the motor at the first position and / or the motor at the second position is zero, it is determined that the motor at the first position and / or the motor at the second position is faulty, and the motor at the first position and / or the motor at the second position is turned off.

[0029] As an implementable method, it also includes: constructing a root cause relationship network of motor pulses, and determining the type of motor fault according to the root cause relationship network based on the number of pulses obtained within a set time.

[0030] As an implementable method, the root cause relationship network of the motor pulse is constructed, and the motor fault type is determined according to the number of pulses obtained within a set time based on the root cause relationship network, specifically: The root cause relationship network of motor pulses is constructed based on the time domain, frequency domain and amplitude characteristics of the motor pulse number as the network input nodes, the hardware status and environmental parameters as the transition nodes, and the fault type as the network output node. Conditional probability is introduced to describe the strength of causal association. According to the number of pulses obtained within the set time, the root cause of the fault is traced back and determined through posterior probability calculation.

[0031] In this embodiment, the first position and the second position may be a backrest and a seat cushion, or a seat cushion and a leg rest.

[0032] The first and second positions of the backrest and seat cushion are described in detail below: Step 1: When the seat is in "zero gravity" or "driving state", the backrest motor starts to move. The Hall sensor of the backrest motor collects the pulse voltage Vin and the low level. The collected pulse voltage is compared with the reference voltage of pin 3 through the comparator 2, and the pulse voltage is converted into the high and low levels that can be received by the microcontroller, namely Vout (3.3V) and low levels. The microcontroller calculates the number of seat motor pulses based on the received high and low levels, such as one high level is one pulse number; the conversion circuit diagram is shown in the figure. Figure 3 ; Step S2: When the backrest motor fails, the number of pulses of the backrest motor is N, that is, the number of high levels is N. The ECU shuts down the faulty motor. The number of pulses of the faulty motor is N. The angle relationship between the number of pulses of the faulty motor and the number of pulses stored in the single-chip microcomputer is calculated. The corresponding angle L° is calculated. For example, if the number of pulses required for the entire stroke of the backrest motor is M, and the angle of the entire stroke is S°, then the angle corresponding to each pulse is S° / M. If the motor is set to uniform motion, then the angle corresponding to N pulses is L°=N*(S° / M). Similarly, the single-chip microcomputer calculates the number of pulses X at the corresponding position of the seat, such as the number of pulses X of the seat cushion motor at the corresponding position of the backrest motor, and calculates the relationship J° between the corresponding position angles based on the number of pulses X at the corresponding position of the seat. For example, if the number of pulses required for the entire stroke of the seat cushion motor is Y, and the angle of the entire stroke is K°, then the angle corresponding to each pulse is K° / Y. If the motor is set to uniform motion, then the angle corresponding to X pulses is J°=X*(K° / Y)). Step 3: Calculate the included angle Z° between the two positions based on the backrest angle L° and the seat cushion angle J° obtained in step 2, where Z° is the absolute angle of J°-L°; Step S4: Based on the angle-comfort correlation data calibrated within the ECU, determining whether the seat is mis-caught or causing discomfort to the occupant, wherein the angle range calibrated within the ECU is G°-E°, and the standard angle G°-E° represents the most comfortable state. A Z° less than G° indicates a risk of mis-caught seat, and a Z° greater than E° indicates an uncomfortable state. Mis-caught seat and comfort status are determined by comparing the Z° and G°-E° values. Step 5: When the seat accidentally clamps the occupant or causes discomfort, adjust the faulty motor to reverse its action, such as the backrest motor to move in the opposite direction, the number of pulses will decrease accordingly, and the corresponding angle will decrease accordingly; adjust the motors in the corresponding positions to move in the opposite direction, such as the seat cushion motor to move in the opposite direction, the number of pulses will decrease, and the corresponding angle will be smaller accordingly; ultimately, the seat will automatically adjust to a comfortable angle for the occupant when a fault occurs. The comfortable angle is the angle range G°-E° that has been calibrated for the human body in advance; Step 6: If the faulty motor is damaged, turn off the faulty motor and send the faulty motor signal to the central control panel or display screen to prompt the replacement of the motor. Only adjust the corresponding position motor to move in the opposite direction. For example, if the seat cushion motor moves in the opposite direction, the number of pulses decreases and the corresponding angle is smaller. Ultimately, it is achieved to prevent the occupants from being accidentally clamped.

[0033] The first and second positions are described in detail below: Step 1: When the seat is in "zero gravity" or "driving state", the seat cushion motor starts to rotate forward. The pulse voltage Vin and the low level are collected by the Hall sensor of the seat cushion motor. The collected pulse voltage is compared by the comparator. The comparator converts the pulse voltage into high and low levels that can be received by the microcontroller, such as Vout (3.3V) and low levels. The number of seat cushion motor pulses is calculated based on the high and low levels, such as one high level equals one pulse number. For the conversion circuit diagram, please refer to Figure 3 ; Step 2: When the seat cushion motor fails, the number of pulses of the seat cushion motor is A, that is, the number of high levels is N. The ECU shuts down the faulty motor. The number of pulses of the faulty motor is A. The angle relationship between the number of pulses of the faulty motor and the number of pulses stored in the single-chip microcomputer is calculated. The corresponding angle B° is calculated. For example, if the number of pulses required for the entire stroke of the seat cushion motor is C and the angle of the entire stroke is H°, then the angle corresponding to each pulse is H° / C. The motor is set to uniform motion; then the angle corresponding to A pulses is B°=A*(H° / C)); Similarly, the single-chip microcomputer calculates the number of pulses I at the corresponding position of the seat cushion, such as the number of pulses I of the leg rest motor at the corresponding position of the seat cushion motor, and calculates the relationship P° between the leg rest angles at the corresponding positions based on the number of pulses I of the leg rest at the corresponding position of the seat. For example, if the number of pulses required for the entire stroke of the leg rest motor is Q and the angle of the entire stroke is T°, then the angle corresponding to each pulse is T° / Q. The motor is set to uniform motion, then the angle corresponding to I pulse is P°=I*(T° / Q)); Step 3: Based on the seat cushion angle B° and leg support angle P° obtained in step 2, calculate the angle R° between the two positions, where R° is the absolute angle of H°-P°; Step 4: Based on the angle-comfort correlation data calibrated within the ECU, determine whether the seat is mis-caught or causing discomfort to the occupant. The angle range calibrated within the ECU is U°-W°, and the standard angle U°-W° represents the most comfortable state. A value of R° less than U° indicates a risk of mis-caught, and a value of R° greater than W° indicates an uncomfortable state. Mis-caught and comfort status are determined by comparing the R° and U°-W° values. Step 5: When the seat is accidentally clamped or causes discomfort to the occupant, the faulty motor is adjusted to reverse its action. For example, if the seat cushion motor moves in the opposite direction, the number of pulses will decrease accordingly, and the corresponding angle will decrease accordingly. The motors at the corresponding positions are adjusted to move in the opposite direction, such as if the leg rest motor moves in the opposite direction. The number of pulses will decrease, and the corresponding angle will decrease accordingly. Ultimately, the seat will automatically adjust to a comfortable angle for the occupant when a fault occurs. The comfortable angle is the angle range U°-W° that has been calibrated in advance for the human body. Step 6: If the faulty motor is damaged, turn off the faulty motor and send the faulty motor signal to the central control screen or display screen to prompt the replacement of the motor. Only adjust the motor at the corresponding position to move in the opposite direction. For example, if the leg rest motor moves in the opposite direction, the number of pulses decreases and the corresponding angle is smaller. Ultimately, it is achieved to prevent the occupants from being accidentally clamped.

[0034] In this embodiment, the method further includes: constructing a root cause relationship network of motor pulses, and determining the motor fault type based on the number of pulses obtained within a set time according to the root cause relationship network, specifically: The root cause relationship network of motor pulses is constructed based on the time domain, frequency domain and amplitude characteristics of the motor pulse number as the network input nodes, the hardware status and environmental parameters as the transition nodes, and the fault type as the network output node. Conditional probability is introduced to describe the strength of causal association. According to the number of pulses obtained within the set time, the root cause of the fault is traced back and determined through posterior probability calculation.

[0035] Specifically, according to the pulse phenomenon layer → intermediate variable layer → fault root cause layer, a multi-layer network is established through causal association to achieve reverse tracing from pulse anomaly to fault type.

[0036] The pulse phenomenon layer includes pulse time, frequency, and amplitude characteristics; the intermediate variable layer includes mechanical status, electrical parameters, environmental interference, and parameter configuration; and the fault root cause layer includes encoder system faults, electrical system faults, mechanical system faults, and environmental and configuration faults. Starting with the pulse, directed edges are directed to the intermediate variables, ultimately converging on the root cause of the fault.
