Description

Technical Field

[0001] This application relates to the field of vehicle control technology, specifically to a control method and control device for a rotating seat in a vehicle. Background Technology

[0002] With the development of automotive technology, consumers have increasingly higher demands for the intelligence of automobiles. Intelligent vehicle control brings a superior driving and riding experience. In terms of intelligent vehicle control, seat control technology is becoming increasingly mature. For example, "welcome" functions are beginning to be applied to the driver and front passenger seats. When someone opens the driver's or front passenger door, the corresponding seat automatically adjusts to a suitable position to facilitate entry and exit. This is especially true for family SUVs, where second-row passengers are often elderly people, women, and children. The actions of elderly people getting in and out of the car, women in skirts, and infants in child seats place a greater demand for convenient entry and exit from the second row. Using rotating seats with welcome / farewell functions can effectively address this need.

[0003] However, the "welcome" function in the vehicle, with its rotating seats moving and rotating during the welcoming and resetting process, undoubtedly affects rear passengers. While some technologies allow for manual adjustment of the rotating seats before seating, this is inconvenient and impacts the passenger experience. Automatic control of seat rotation and movement, on the other hand, can easily cause scrapes or contact with rear passengers, resulting in a poor riding experience. Summary of the Invention

[0004] In related technologies, the automatic rotation function of the rotating seats cannot accurately determine the space required by the front and rear passengers. This can easily cause the seats to scrape or touch the rear passengers during the welcoming motion, resulting in a poor riding experience.

[0014] By combining the initial position of the front passenger's legs against the seat cushion with the human joint comfort verification results of the digital human body model, the minimum rotational envelopment envelope data corresponding to different body sizes of the front passenger can be determined.

[0015] In conjunction with the first aspect, in one implementation, determining the minimum rear envelope parameter required for the rear passengers based on their body size information includes:

[0016] The front rotating seats in the human body model database are moved to their maximum position while ensuring sufficient seating space for rear passengers.

[0017] The distance from the front rotation center to the vehicle's B-pillar at this position is calculated as the minimum envelope parameter for the rear row.

[0018] In conjunction with the first aspect, in one embodiment, determining the minimum front-seat rotation envelope parameters required for the front-seat passenger to sit based on the front-seat passenger's body size information includes:

[0020] The minimum rotational envelope distance of the front row is determined based on the minimum space in the front row.

[0021] In conjunction with the first aspect, in one embodiment, the step of inputting the body size information of the front passenger into the human body model database to obtain the minimum front space required for the rotating seat to rotate when the front passenger gets in and out of the vehicle includes:

[0022] Input the body size information of the front passenger into the human body model database to obtain the minimum front space distance between the rotation center of the front vehicle's rotating seat and the minimum envelope of the front passenger's toes required for rotation.

[0023] In conjunction with the first aspect, in one embodiment, determining whether the vehicle's rotating seat performs a welcoming action based on the minimum rotational envelope parameter of the front row and the minimum rotational envelope parameter of the rear row includes: when the minimum rotational envelope parameter of the rear row is greater than the minimum rotational envelope parameter of the front row, driving the rotating seat to move to the target position of the rotating seat in the front row.

[0024] Control the rotating seat to perform the rotation action.

[0025] In conjunction with the first aspect, in one embodiment, the step of driving the swivel seat to move to the target position of the front row swivel seat includes:

[0026] The minimum seating space required for rear passengers is defined as the distance from the toe point of the rear passenger's smallest enveloping foot to the center of rotation of the front rotating seat in the X direction of the vehicle.

[0027] The seat clearance distance is determined based on the vehicle type, and the target position for rotating seat movement is determined based on the seat clearance distance and the minimum seating space required by rear passengers.

[0028] In conjunction with the first aspect, in one embodiment, after the control of the rotating seat to perform the rotation action, it further includes:

[0029] Once the passengers in the front swivel seats have finished sitting, the swivel seats will be rotated back to their original positions.

[0041] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.

[0042] In related technologies, the automatic rotation function of the rotating seats cannot accurately determine the space required by the front and rear passengers. This can easily cause the seats to scrape or touch the rear passengers during the welcoming motion, resulting in a poor riding experience.

[0043] Firstly, such as Figure 1 As shown, this application provides an embodiment of a control method for a vehicle rotating seat, the control method for the vehicle rotating seat including:

[0044] Step S1: Establish a human body model database for a specific population based on the correspondence between different body sizes of the specific population and the minimum human seating space envelope data and the minimum human rotation envelope data required for getting on and off the vehicle.

[0045] In some preferred embodiments, a database of anthropometric models of specific populations can be created based on RAMSIS software, representing the minimum seating space envelope and the minimum rotational boarding / alighting envelope required for passengers of different body types. Optionally, for vehicles applied to the region, a database of anthropometric models of Chinese people can be established based on the body dimensions of people in that region.

[0046] It should be noted that RAMSIS software is a high-efficiency CAD tool for occupant simulation and automotive ergonomics design. It can provide detailed CAD human body models of various body proportions from different countries, and can also be used for simulation analysis of driving, riding, operation, field of vision, and getting in and out of the vehicle.

[0047] Specifically, the process of establishing the human body model database mentioned above includes:

[0048] Step S1a: Combine the recommended range of human joint comfort for rear passengers of different body sizes with the human joint comfort verification results of the digital human body model to determine the minimum seating space envelope data corresponding to different body sizes of rear passengers.

[0049] Specifically, the recommended range for rear-seat human joint comfort (knee angle ≥ 85°) is determined based on the RAMSIS human joint comfort calibration results; the space required for the minimum rotation envelope is determined based on the initial position of the human model's legs touching the seat cushion, also in conjunction with the RAMSIS human joint comfort calibration results. The specific correspondence establishment process can be found in the table below:

[0050]

[0051] It should be noted that P1, P2...Pn, where Pn represents the nth percentile, indicating that in the distribution of human body dimensions, n% of the human body dimensions are less than or equal to this value. For example, the P95 value for height means that 95% of people are shorter than or equal to this value. As shown in the table above, different percentiles of human body dimensions correspond to different envelope codes, and the envelope codes correspond to different distances from the rear seat toe point to the center of the front rotating seat (the toe point and the second-row seat structure are not in contact).

[0052] It's worth noting that when the front rotating seats perform the "welcoming" action, they must first be moved to a suitable position before rotating. The reason this application establishes a model to calculate and calibrate the minimum seating space envelope data for rear passengers is to calculate the distance from the toe point of the rear passenger envelope to the center of the front rotating seat, while maintaining rear passenger comfort. Based on this distance, the range of positions that will not be affected by the rotation of the front rotating seats can be determined.

[0053] Step S1b: Combine the initial position of the front passenger's legs against the seat cushion with the human joint comfort calibration results of the digital human body model to determine the minimum rotational envelopment envelope data corresponding to different body sizes of the front passenger. The specific calibration process is shown in the table below:

[0054]

[0055] It should be noted that different percentiles of human body size correspond to different envelope codes Bn, which correspond to the minimum spatial distance required for rotation and the distance from the rotation center to the vehicle's B-pillar.

[0056] It is worth noting that this application needs to calculate and calibrate the minimum rotational envelopment data required for the front passenger to get into the vehicle based on the body size of the front passenger. This envelopment data includes: the minimum space distance required for the passenger to rotate during the getting in and out of the vehicle, and the corresponding distance from the rotation center of the rotating seat to the B-pillar of the vehicle at this time.

[0057] Preferably, the minimum spatial distance R required for passengers to rotate during boarding and alighting in the table above is... y The distance from the center of rotation of the front swivel seat to the foremost point of the front passenger's toes, plus a 20mm gap, is the minimum achievable rotation envelope L for the front passenger. In the table above, the distance from the center of rotation to the B-pillar represents the achievable rotation envelope L for the front seats. x .

[0058] Specifically, the rotational envelope L that can be achieved in the front row x To ensure rear passenger space and with the front rotating seats in their final movable position, the distance from the front rotation center to the B-pillar (the B-pillar measurement area can be set at a 100mm cross-section on the carpet).

[0059] Step S2: Collect body size information of front-seat passengers and rear-seat passengers.

[0060] In some implementations, step S2 includes: installing a camera and a distance sensor on the vehicle, and using the camera to collect information such as the gender and height of passengers waiting to board in the front row and passengers already seated in the back row.

[0061] Step S3: Determine the minimum rotation envelope parameters required for the front-seat passengers based on their body size information.

[0062] Specifically, step S3 above includes:

[0063] Step S3a: Input the body size information of the front passenger into the human body model database to obtain the minimum front space required for the front passenger to rotate the seat when getting in and out of the vehicle.

[0064] Specifically, the body size information of the front passenger is input into the human body model database. Based on the calibration correspondence of the human body data model in step S1b above, the distance between the rotation center of the front row and the minimum envelope toes required for the front passenger to rotate can be obtained, and this distance is used as the minimum spatial distance of the front row.

[0065] Step S3b: Determine the minimum rotational envelope distance of the front row based on the minimum spatial distance of the front row.

[0066] Preferably, to improve comfort, the minimum rotational envelope distance R of the front row is... y Add 20mm of clearance (comfort distance) to the minimum front row space distance mentioned above.

[0067] Step S4: Determine the minimum envelope parameters required for the rear passengers based on their body size information.

[0068] Specifically, the front rotating seats in the human body model database are moved to their maximum position while ensuring sufficient seating space for rear passengers. The distance from the front rotation center to the vehicle's B-pillar at this position is calculated as the minimum envelope parameter L for the rear seats. x .

[0069] Step S5, as follows Figure 2 As shown, based on the minimum rotational envelope parameter R of the front row y and the minimum envelope parameter L of the back row x Determine whether the vehicle's rotating seats perform a welcoming gesture.

[0070] Step S5 above includes several scenarios, specifically:

[0071] Case 1: When the minimum envelope parameter L of the back row x Not greater than the minimum rotational envelope parameter R of the front row y If the message indicates that the welcome mode cannot be started, a message will be displayed.

[0072] It should be noted that in the above situation, rotating the front passenger seat when boarding would affect the seating space for the rear passengers, and therefore the rotating welcoming action cannot be performed.

[0073] Scenario 2: When the minimum envelope parameter L of the back row is... x Greater than the minimum rotational envelope parameter R of the front row y Then, the rotating seat is driven to move to the target position n of the rotating seat in the front row.

[0074] It should be noted that the above situation indicates that the rotation of the front-seat passengers upon boarding will not affect the seating space of the rear-seat passengers.

[0075] Furthermore, the target position n for moving the rotating seat to the front row includes:

[0076] Step A: Determine the target location n.

[0077] Specifically, based on the calibration results of the human body model database, the distance from the toe point of the rear passenger's minimum envelope to the rotation center of the front rotating seat in the X direction of the vehicle is obtained, and this distance is taken as the minimum seating space S required by the rear passenger. x (At this point, the rear passenger's toes are not touching the front swivel seat). Furthermore, based on the minimum seating space S required by the rear passenger... x The sum of the seat clearance distance m is used as the distance the front seat moves, thus obtaining the distance the seat moves according to the front seat (S). x The position n after +m).

[0078] It should be noted that the seat clearance distance m needs to allow for both foot space and environmental clearance. Due to different seat structures, the seat clearance distance m needs to be calibrated during the design of specific vehicle models.

[0079] Step B: Control the rotating seat to move to the target position n and perform the rotation action.

[0080] Scenario 3: If the body size information of the rear passengers shows that there are no rear passengers, the rotating seat will be directly moved to the first preset position, which satisfies the maximum envelope B of the front passengers. max .

[0081] Step S6: After confirming that the passengers in the front rotating seats have finished sitting, drive the rotating seats to rotate and reset. Adjust the rotating seats to move back to the reset position according to the seating position of the rear passengers.

[0082] It should be noted that step S6 is executed only under cases two and three in step S5.

[0083] In the first embodiment provided in this application, step S6 includes: sensing that someone is in the front seat based on the pressure sensor on the front rotating seat and maintaining it for 5 seconds before resetting the position.

[0084] In the second embodiment provided in this application, step S6 includes: after receiving the command to start and reset the vehicle, executing the reset position.

[0085] It is worth noting that the two embodiments described above can be applied simultaneously to the control method described in this application.

[0086] Furthermore, the reset position of this application needs to be determined based on the distance sensor and the seating position of the rear passengers, after reserving 20mm of space for the knees, legs, and feet; if there are no rear passengers, the reset position is the position after rotating back to the center after the welcoming ceremony.

[0087] Specifically, the decision control process for steps S5 and S6 is shown in the table below:

[0088]

[0089] It should be noted that steps S1 to S6 described above are only one specific implementation of this application. The execution order can be changed according to actual usage requirements.

[0090] The control principle of this application includes: when there are no passengers in the rear row, the welcoming and reset positions are determined according to the maximum rotation envelope required by the front row; when there are passengers in the rear row, the rear limit position of the front seats is determined according to the minimum seating space required by the rear passengers, and it is calculated whether the entry and exit envelope that the front row can achieve at this time meets the rotation envelope space required by the front passengers. If it does not meet the requirements, a prompt will be made that the welcoming mode cannot be entered; if it does meet the requirements, the front seats will be controlled to move back to the rear limit position and then rotate to welcome passengers; after the passengers are seated, the front seats rotate to reset.

[0091] In one specific embodiment provided in this application, such as Figure 1 and Figure 2 As shown, the vehicle rotating seat control method of this application can be applied to the second-row rotating seat control strategy of MPV (Multi-Purpose Vehicle) models.

[0092] In summary, this application improves the accuracy of the automatic rotating welcome function of the rotating seat by collecting and judging the body dimensions of front-seat passengers and rear-seat passengers, and then driving the rotating seat to move according to the judgment results. This avoids the rotating seat continuing to perform the "welcome" action when there is a risk of touching the rear-seat passengers, thus preventing the rear-seat passengers from being scratched or touched.
