[0056] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features therein can be combined with each other in the absence of conflict.

[0057] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0058] An embodiment of the present disclosure provides a vehicle seat control method, which is described below in conjunction with specific embodiments.

[0059] Figure 1 This is a flow chart of a vehicle seat control method provided by an embodiment of the present disclosure. The method can be applied to Figure 2 The application scenario shown includes a seat controller (or body controller) 21, a left seat 22, and a right seat 23. The seat controller 21 is used to collect information and perform logic drive output control on the left seat 22 and the right seat 23. The seat controller (or body controller) can be an on-board device, such as a car computer, a smartphone, a PDA, a tablet computer, a laptop computer, an all-in-one computer, an intelligent driving device, etc. It is understood that the vehicle voice control method provided by the embodiments of the present disclosure can also be applied in other scenarios.

[0060] like Figure 1 As shown, the method includes the following specific steps:

[0061] S101. Obtain the adjustment time of the left seat, the adjustment drive duty cycle of the left seat, and the adjustment coefficient of the left seat during the seat adjustment process. The seat adjustment process is one of the seat lifting process and the seat laying down process. During the seat adjustment process, the movement trend of the left seat and the right seat is the same. The adjustment drive duty cycle is one of the lifting drive duty cycle and the laying down drive duty cycle corresponding to the seat adjustment process.

[0062] S102. Acquire the adjustment time of the right seat, the adjustment drive duty cycle of the left seat, and the adjustment coefficient of the right seat during the seat adjustment process, wherein the adjustment time of the left seat and the adjustment time of the right seat have the same adjustment travel.

[0063] Specifically, the seat adjustment process includes a seat lifting process and a seat reclining process.

[0064] For seat adjustment, when the duty cycle increases, the input voltage and current of the motor driving the seat adjustment also increase, and the output torque and speed also increase accordingly, making the seat adjustment speed faster. Conversely, when the duty cycle decreases, the input voltage and current of the motor driving the seat adjustment decrease, and the output torque and speed also decrease, making the seat adjustment speed slower.

[0065] It should be noted that the execution order of the above S101 and S102 is not fixed. The two can be executed one after another or simultaneously, and the embodiment of the present disclosure does not limit this.

[0066] For example, during pre-production vehicle commissioning, personnel adjust the left and right seats simultaneously, ensuring that their travel is the same. The system captures the time taken for the left and right seats to adjust, obtaining the left and right seat adjustment times. It also captures the duty cycles used to drive the left and right seats, obtaining the left and right seat adjustment drive duty cycles. The left and right seat adjustment coefficients are pre-set values ​​used to control the seat adjustment speed in conjunction with these adjustment times and duty cycles.

[0067] S103: If the adjustment speed of the left seat is different from the adjustment speed of the right seat, determine a target adjustment seat, where the target adjustment seat is either the left seat or the right seat.

[0068] Specifically, the speed of adjustment between the left and right seats can be determined based on the adjustment time of the left and right seats. Since the adjustment time of the left and right seats corresponds to the same adjustment distance, the seat with the shorter adjustment time has a faster adjustment speed. For example, the seat with the shorter adjustment time is determined as the target seat for adjustment.

[0069] S104. Update the adjustment drive duty cycle of the target adjustment seat to the product of three target parameters, where the three target parameters are the adjustment coefficient of the target adjustment seat, the adjustment drive duty cycle of the target adjustment seat, and the ratio of the adjustment time of the target adjustment seat to the adjustment time of the seat on the other side.

[0070] The purpose of updating the adjustment drive duty cycle of the target adjustable seat is to change the adjustment speed of the target adjustable seat. For example, if the seat with the shortest adjustment time is determined as the target adjustable seat, the adjustment speed of the target adjustable seat needs to be reduced, and therefore the adjustment drive duty cycle of the target adjustable seat needs to be reduced.

[0071] Since the adjustment time of the target adjustment seat is less than the adjustment time of the seat on the other side, the ratio of the target adjustment seat adjustment time to the adjustment time of the seat on the other side is less than one. Multiplying this ratio with the original adjustment drive duty cycle can achieve the purpose of reducing the adjustment drive duty cycle.

[0072] Specifically, the adjustment drive duty cycle of the target adjustment seat is updated in combination with the adjustment coefficient, and the specific calculation method is as follows:

[0073]

[0074] Among them, W *is the adjustment drive duty cycle of the target adjustable seat after update, μ is the adjustment coefficient of the target adjustable seat, W is the adjustment drive duty cycle of the target adjustable seat before update, y is the adjustment time of the target adjustable seat, and z is the adjustment time of the other side seat.

[0075] It is understandable that when the seat on the side with a slower adjustment speed is used as the target adjustment seat, its adjustment formula can be mathematically derived based on the above formula, which will not be repeated here.

[0076] The embodiment of the present disclosure obtains the adjustment time of the left seat, the adjustment drive duty cycle of the left seat, and the adjustment coefficient of the left seat during the seat adjustment process, wherein the seat adjustment process is one of the seat lifting process and the seat laying down process, and the movement trend of the left seat and the right seat during the seat adjustment process is the same, and the adjustment drive duty cycle is one of the lifting drive duty cycle and the laying down drive duty cycle corresponding to the seat adjustment process; obtains the adjustment time of the right seat, the adjustment drive duty cycle of the left seat, and the adjustment coefficient of the right seat during the seat adjustment process, wherein the adjustment time of the left seat and the adjustment time of the right seat have the same adjustment stroke; if the adjustment speed of the left seat is different from the adjustment speed of the right seat, the target adjustment seat is determined, and the target adjustment seat is the adjustment speed of the left seat and the right seat. any one of them; updating the adjustment drive duty cycle of the target adjustment seat to the product of three target parameters, wherein the three target parameters are respectively the adjustment coefficient of the target adjustment seat, the adjustment drive duty cycle of the target adjustment seat, and the ratio of the adjustment time of the target adjustment seat to the adjustment time of the seat on the other side; utilizing the adjustment time, adjustment drive duty cycle and adjustment coefficient of the left and right seats, when the adjustment speeds of the left and right seats are different, updating the adjustment drive duty cycle of one of the seats to the product of the adjustment coefficient of the target adjustment seat, the adjustment drive duty cycle of the target adjustment seat, and the ratio of the adjustment time of the target adjustment seat to the adjustment time of the seat on the other side, so that when the seats are adjusted by the updated adjustment drive duty cycle, the adjustment speeds of the left and right seats are the same, thereby achieving consistency in the seat adjustment speeds when the left and right seats are simultaneously controlled.

[0077] On the basis of the above embodiment, after updating the adjustment drive duty cycle of the target adjustable seat to the product of three target parameters, the method further includes: obtaining the left-side running time of the left seat running from the Hall zero point to the Hall maximum value, and the right-side running time of the left seat running from the Hall zero point to the Hall maximum value; updating the adjustment coefficient of the target adjustable seat to the ratio of the first running time to the second running time, the first running time being the smallest one between the left-side running time and the right-side running time, and the second running time being the other one between the left-side running time and the right-side running time except the first running time.

[0078] Specifically, the left side running time of the left seat from the Hall zero point to the Hall maximum value and the right side running time of the left seat from the Hall zero point to the Hall maximum value are collected by the Hall sensor corresponding to the actuator driving the seat.

[0079] After the adjustment drive duty cycle of the target adjustment seat is updated, the adjustment speed of the target adjustment seat changes, and the corresponding adjustment time of the target adjustment seat also changes. At this time, the adjustment coefficient of the target adjustment seat needs to be updated so that the updated adjustment coefficient is more in line with the current requirements of the coordinated control of the left and right seats. The specific calculation method for updating the adjustment coefficient of the target adjustment seat is as follows:

[0080]

[0081] where μ * is the updated adjustment coefficient, t1 is the first running time, and t2 is the second running time.

[0082] The embodiment of the present disclosure updates the adjustment drive duty cycle of the target adjustment seat to the product of three target parameters, and obtains the left-side running time of the left seat running from the Hall zero point to the Hall maximum value, and the right-side running time of the left seat running from the Hall zero point to the Hall maximum value; updates the adjustment coefficient of the target adjustment seat to the ratio of the first running time to the second running time, the first running time being the smallest of the left-side running time and the right-side running time, and the second running time being the other of the left-side running time and the right-side running time except the first running time. After updating the adjustment drive duty cycle of the target adjustment seat, the adjustment coefficient of the target adjustment seat is updated based on the updated seat adjustment time, so that the updated adjustment coefficient can participate in the next adjustment drive duty cycle update, thereby ensuring the driving stability of the collaborative control.

[0083] At the same time, the logic control and drive of the embodiment of the present disclosure are centrally processed by the seat controller (or body controller), wherein the actuator used to drive the seat only needs to be configured with a corresponding Hall sensor without adding other hardware, which facilitates troubleshooting, function updates and iterations, is adaptable to multiple actuator controls, and has strong portability.

[0085] Accordingly, when the target seat is the left seat, the adjustment drive duty cycle of the target seat is updated to the product of three target parameters, including: updating the left lift drive duty cycle to the product of the adjustment coefficient of the left seat, the left lift drive duty cycle, and the ratio of the left lift time to the right lift time. The specific calculation method is as follows:

[0086]

[0087] Among them A * is the updated left lift drive duty cycle, m is the adjustment coefficient of the left seat, A is the left lift drive duty cycle, a is the left lift time, and c is the right lift time.

[0088] Alternatively, when the target seat is the right seat, updating the target seat's adjustment drive duty cycle to the product of three target parameters includes updating the right lift drive duty cycle to the product of the right seat's adjustment coefficient, the right lift drive duty cycle, and the ratio of the right lift time to the left lift time. The specific calculation method is as follows:

[0089]

[0090] Among them C * is the updated left-side lift drive duty cycle, n is the adjustment coefficient of the left seat, C is the left-side lift drive duty cycle, a is the left-side lift time, and c is the right-side lift time.

[0091] In some embodiments, the seat adjustment process includes a seat folding process; obtaining the adjustment time of the left seat, the adjustment drive duty cycle of the left seat, and the adjustment coefficient of the left seat during the seat adjustment process includes: obtaining the left-side folding time of the left seat, the left-side folding drive duty cycle of the left seat, and the adjustment coefficient of the left seat; obtaining the adjustment time of the right seat, the adjustment drive duty cycle of the left seat, and the adjustment coefficient of the right seat during the seat adjustment process includes: obtaining the right-side folding time of the right seat, the right-side folding drive duty cycle of the right seat, and the adjustment coefficient of the right seat.

[0092] Accordingly, when the target adjustable seat is the left seat, the adjustment drive duty cycle of the target adjustable seat is updated to the product of three target parameters, including: updating the left reclining drive duty cycle to the product of the adjustment coefficient of the left seat, the left reclining drive duty cycle, and the ratio of the left reclining time to the right reclining time.

[0093]

[0094] Among them B * is the updated left-side reclining drive duty cycle, m is the adjustment coefficient of the left seat, B is the left-side reclining drive duty cycle, b is the left-side reclining time, and d is the right-side reclining time.

[0095] Alternatively, when the target adjustable seat is the right seat, updating the adjustment drive duty cycle of the target adjustable seat to the product of three target parameters includes: updating the right reclining drive duty cycle to the product of the adjustment coefficient of the right seat, the right reclining drive duty cycle, and the ratio of the right reclining time to the left reclining time. The specific calculation method is as follows:

[0096]

[0097] Among them D * is the updated left-side reclining drive duty cycle, n is the adjustment coefficient of the left seat, D is the left-side reclining drive duty cycle, b is the left-side reclining time, and d is the right-side reclining time.

[0098] Figure 3 This is a diagram of the vehicle seat control method architecture provided by another embodiment of the present disclosure.

Specifically, four timers are established in the software, which self-learn to obtain the left-side lift time a for the left seat, the left-side folding time b for the left seat, the right-side lift time c for the right seat, and the right-side folding time d for the right seat. Furthermore, the onboard device software updates the adjustment drive duty cycle and adjustment coefficient of the target adjustable seat based on the logic in the above embodiment, and drives the left and right seats according to the updated adjustment drive duty cycle.
