Description

Technical Field

[0001] The present application relates to the field of vehicle control technology, and in particular to a control method and a control device for a rotating seat of a vehicle. Background Art

[0002] With the development of automobile technology, consumers have higher and higher requirements for the intelligence of automobiles. The intelligent control of automobiles will bring a higher driving experience to drivers and passengers. In terms of intelligent control of automobiles, the intelligent control technology of vehicle seats is becoming more and more mature. For example, the "welcome" function has begun to be applied to the driver's seat and the co-pilot seat of the vehicle. That is, when someone opens the door of the driver's seat or the co-pilot seat, the car seat in the corresponding position will automatically adjust to the appropriate position to provide convenience for the driver and passengers to get on the car. Especially for multi-purpose vehicles for families, the second row passengers are mostly elderly people, women, and children. The elderly getting on and off the car, women getting on and off the car in skirts, and placing infants and young children in child seats put forward higher requirements for the convenience of getting on and off the second row. Using rotating seats to add the welcoming function can better meet this demand.

[0003] However, the "welcome" function is set on the vehicle, and the rotating seat will undoubtedly affect the rear passengers during the movement and rotation process of welcoming and resetting. In the related technology, the rotating seat can be manually adjusted to slide and rotate before sitting. However, the adjustment is not convenient enough, which affects the passengers' riding experience. The automatic control of the seat rotation and movement process is easy to scratch and touch the rear passengers, resulting in a poor riding experience. Summary of the invention

[0041] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0042] In the related technology, the automatic rotation function of the rotating seat cannot accurately determine the space required by the front and rear passengers. As a result, it is easy to scratch and touch the rear passengers during the welcoming action, resulting in a poor riding experience.

[0043] First, as Figure 1 As shown, the present application provides an embodiment of a method for controlling a rotating seat of a vehicle, and the method for controlling a rotating seat of a vehicle includes:

[0044] Step S1, establishing a human body model database for a specific group of people according to the corresponding relationship between different body sizes of the specific group of people and the minimum seating space envelope data of the human body and the minimum rotation envelope data required for the human body to get on and off the vehicle.

[0045] In some preferred implementations, a human body model database for a specific group of people with the minimum seating space envelope and the minimum required rotation envelope for getting on and off the vehicle for passengers of different body types can be created based on RAMSIS software. Optionally, a human body model database for Chinese people can be established based on the body dimensions of people in the region for vehicles used in the region.

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

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

[0048] Step S1a, combining the recommended range of human joint comfort for rear passengers with different body sizes with the human joint comfort verification result 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 of rear seat human joint comfort (knee angle ≥ 85°) is determined in combination with the RAMSIS human joint comfort verification results; the space required for the minimum rotation envelope is based on the initial position of the human model's legs against the seat cushion, and is determined in combination with the RAMSIS human joint comfort verification results. The specific corresponding relationship establishment process can be referred to the following table:

[0050]

[0051] It should be noted that the above P1, P2..Pn, Pn is expressed as the nth percentile, indicating that in the distribution of human body size, n% of the human body size is less than or equal to this value. For example, the P95 value of the height item means that 95% of the people are less than or equal to this value. As shown in the above table, different percentile human body sizes correspond to different envelope codes, and the envelope codes correspond to different distances from the rear envelope toe point to the center of the front swivel seat (toe point and the second row seat structure are zero-stick).

[0052] It is worth noting that when the front swivel seat performs the "welcoming" action, it must first move to a suitable position and then rotate. The reason why this application establishes a model to measure and calibrate the minimum seating space envelope data corresponding to the rear passengers is to measure the distance from the rear envelope toe point to the center of the front swivel seat while maintaining the comfort of the rear passengers. Based on this distance, the position range of the front swivel seat that will not affect the rear passengers when it rotates can be obtained.

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

[0054]

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

[0056] It is worth noting that the present application needs to calibrate the minimum rotation envelope data required for the front-row passengers to get on the vehicle based on the body size of the front-row passengers. The envelope data includes: the minimum spatial distance required for the passenger to rotate during the getting on and off the vehicle and the corresponding distance from the rotation center of the rotating seat to the B-pillar of the vehicle.

[0057] Preferably, the minimum space distance R required for the passenger to get on and off the vehicle during the rotation process in the above table is y The distance from the rotation center to the B-pillar in the table above is the rotation envelope L that can be achieved in the front row. x .

[0058] Specifically, the rotation envelope L that can be achieved in the front row x To meet the rear seat space requirements and when the front swivel seats are in the rearmost movable position, the distance from the front row's rotation center to the B-pillar (the B-pillar measurement area can be set at the 100-degree section on the carpet) is calculated.

[0059] Step S2: Collecting body size information of front row passengers and rear row passengers.

[0060] In some implementations, the above 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 the front-row passengers waiting to get on the vehicle and the rear-row passengers already seated.

[0061] Step S3: determining the front row minimum rotation envelope parameters required for the front row passenger to sit according to the front row passenger's body size information.

[0062] Specifically, the above step S3 includes:

[0063] Step S3a: input the body size information of the front-row passenger into the human body model database to obtain the minimum front-row space required for rotating the seat when the front-row passenger gets on or off the vehicle.

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

[0065] Step S3b, determining the front row minimum rotation envelope distance according to the front row minimum spatial distance.

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

[0067] Step S4: determining the rear minimum envelope parameters required by the rear passengers according to the rear passenger body size information.

[0068] Specifically, the front row swivel seat in the human body model database is moved to the maximum movement position while satisfying the rear row passenger seating space condition. The distance from the front row rotation center to the vehicle B-pillar at this position is calculated as the rear row minimum envelope parameter L x .

[0069] Step S5: Figure 2 As shown, according to the front row minimum rotation envelope parameter R y and the rear minimum envelope parameter L x Determine whether the vehicle's rotating seat is performing a welcoming action.

[0070] The above step S5 includes multiple situations, specifically including:

[0071] Case 1: When the rear minimum envelope parameter L x Not greater than the minimum rotation envelope parameter R of the front row y , it will prompt that the welcome mode cannot be started.

[0072] It should be noted that the above situation means that the rotation of the front passengers when getting on the vehicle will affect the riding space of the rear passengers, and therefore the rotating welcoming action cannot be performed.

[0073] Case 2: When the rear minimum envelope parameter L x Greater than the minimum rotation envelope parameter R of the front row y , then the swivel seat is driven to move to the target position n of the swivel seat in the front row.

[0074] It should be noted that the above situation shows that the rotation of the front passengers in the car will not affect the riding space of the rear passengers.

[0075] Furthermore, the above-mentioned driving the swivel seat to move to the target position n of the swivel seat in the front row includes:

[0076] Step A: determine the target position n.

[0077] Specifically, based on the calibration results of the human body model database, the distance from the toe point of the minimum envelope of the rear-seat human body to the rotation center of the front-row rotating seat in the vehicle X direction is obtained, and this distance is used as the minimum seating space S required by the rear-seat passengers. x (At this time, the toes of the rear passengers are zero contact with the front swivel seats.) Further, according to the minimum seating space S required by the rear passengers, x The sum of the seat avoidance distance m is used as the distance value of the front seat movement, and then the distance value (S x +m) after position n.

[0078] It should be noted that the seat avoidance distance m needs to reserve both foot and environmental clearance. Due to different seat structures, the seat avoidance distance m needs to be calibrated when designing specific vehicles.

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

[0080] Case 3: The body size information collection result of the rear passengers shows that there are no passengers in the rear seats, so the swivel seat is directly driven to move 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 row swivel seats have finished sitting, the swivel seats are driven to rotate and reset, and the swivel seats are adjusted to translate back to the reset position according to the seating positions of the rear row passengers.

[0082] It should be noted that the above step S6 is only performed when situation 2 and situation 3 exist in step S5.

[0083] In the first embodiment provided by the present application, step S6 includes: according to the pressure sensor on the front rotating seat, a reset position is executed after sensing that there is someone on the front seat and the seat remains there for 5 seconds.

[0084] In the second embodiment provided by the present application, step S6 includes: after receiving the instruction to start resetting the whole vehicle, executing the resetting position.

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

[0086] Furthermore, the reset position of the present application needs to be determined according to the distance sensor and based on the seating position of the rear passengers, leaving 20mm of knee, leg and foot space; if there are no rear passengers, the reset position is to rotate back to the normal position after the welcoming is completed.

[0087] Specifically, the judgment control process of step S5 and step S6 is shown in the following table:

[0088]

[0089] It should be noted that the above steps S1 to S6 are only a specific implementation of the present application, and the execution order thereof can be changed according to actual use requirements.

[0090] The control principle of the present application includes: when there are no passengers in the back row, the welcoming and resetting positions are determined according to the required envelope of the maximum rotation of the front row; when there are passengers in the back 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 envelope of getting on and off the vehicle that can be achieved in the front row at this time meets the required rotation envelope space of the front passengers. If not, it is prompted that the welcoming mode cannot be entered; if so, the front seats are controlled to move backward to the rear limit position and then rotate to welcome guests; the front seats are rotated and reset after the passengers are seated.

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

[0092] To summarize, the present application improves the accuracy of the automatic rotation welcome function of the rotating seat by collecting and judging the body dimensions of the front-seat passengers and the back-seat passengers, and then driving the rotating seat to move according to the judgment results, thereby avoiding the rotating seat continuing to perform the "welcome" action when there is a risk of touching the back-seat passengers, causing the back-seat passengers to be scratched or touched.
