[0055] To better understand the above technical solutions, the following will describe the above technical solutions in detail with reference to specific implementation methods. It should be understood that the embodiments of this disclosure and the specific features in the embodiments are detailed descriptions of the technical solutions of this application, rather than limitations on the technical solutions of this application. In the absence of conflict, the embodiments of this application and the technical features in the embodiments can be combined with each other.

[0056] Vehicles typically have a center armrest, such as the center armrest of the passenger side dashboard, which is installed to provide arm support for the driver and ensure the comfort of the right hand.

[0057] With the increasing prevalence of large central control screens in vehicles and the growing number of operating functions, drivers need to frequently touch the central control screen to perform various operations and adjustments. As a result, the frequency of changes in the position of the driver's arm is also increasing. The existing central armrest is in a fixed position or can only be manually controlled to slide within a limited space. Due to the limited length of the central armrest and the driver's own physical condition, the right elbow cannot be supported. When operating frequently, the arm will feel very tired. Thus, the existing central armrest is difficult to effectively support the driver's arm with its frequent position changes.

[0058] In view of this, this application provides a method for controlling a central armrest, which is applied to a vehicle, the vehicle including a central armrest. Please refer to... Figure 1 , Figure 1 This is a flowchart of a central handrail control method in an embodiment of this application. The method includes:

[0059] S101. Determine the driver's target driving state based on the driver's driving operation signals.

[0060] S102. Based on the matching relationship between the driver's driving state and the position information of the center armrest, determine the target position information of the center armrest corresponding to the driver's target driving state.

[0061] S103. Based on the target position information of the central handrail and the actual position information of the central handrail, determine the target displacement of the central handrail.

[0062] S104. Control the movement of the central handrail according to the target displacement of the central handrail.

[0063] It is understood that the aforementioned central armrest control method can be applied to vehicles. Vehicles can be cars, trucks, buses, etc. The embodiments of this application do not limit the specific structure and purpose of the vehicle to which the central armrest control method is applied.

[0064] The following describes how the operation S101 is performed in the central handrail control method provided in the embodiments of this application.

[0065] A driver operates a vehicle in various driving states, each with a different elbow position and requiring a different center armrest position. Generally, based on the driver's elbow position, there are three typical operating conditions: Figure 2 As shown, the first situation is when gripping the steering wheel to control the vehicle to drive in a straight line or turn, in which the center armrest 202 needs to provide comfortable support for the elbow 201; the second situation is when operating the touch screen, which also requires the center armrest 202 to provide comfortable support for the elbow 201; the third situation is when resting with the elbow resting on the center armrest, which still requires the center armrest 202 to provide comfortable support for the elbow 201.

[0066] Therefore, the driver has multiple driving states, including gripping the steering wheel, touching the central control screen, and resting.

[0067] Location information for multiple central handrails includes:

[0068] The first position information corresponds to the state of gripping the steering wheel, the second position information corresponds to the state of touching the central control screen, and the third position information corresponds to the state of rest.

[0069] Understandably, the first position information indicates that the center armrest 202 provides comfortable support for the driver's elbow 201 when gripping the steering wheel; the second position information indicates that the center armrest 202 provides comfortable support for the driver's elbow 201 when touching the central control screen; and the third position information indicates that the center armrest 202 provides comfortable support for the driver's elbow 201 when resting.

[0070] It is understandable that the position of the driver's elbow 201 is different when gripping the steering wheel, touching the central control screen, and resting. The center armrest 202 needs to be moved to the corresponding position in different driving states to provide comfortable support for the elbow 201.

[0071] The first, second, and third position information can be set to fixed values. Through preliminary human body model calculations or user evaluations, the position information of the central armrest applicable to drivers with body characteristics ranging from 5% to 95% can be determined under three driving conditions.

[0072] For example, an adjustable test bench can be used to conduct subjective evaluations of different percentile human bodies to determine their desired comfortable elbow position under different driving conditions. The adjustable test bench includes a seat, an adjustable center armrest, and an adjustable center screen. The seat can be adjusted forward and backward, high and low, and angle. The armrest can at least slide forward and backward, and the screen can be removed or replaced. This is used to verify the operation of key points of the waist, elbow, and fingertips of users of different car models, so as to find their most desired comfortable elbow rest position. The specific operation will not be described in detail here.

[0073] Taking the driver's driving state as gripping the steering wheel, touching the central control screen, or resting as an example, the specific steps of performing the above S101 operation include:

[0074] If a first grip signal from the driver on the left side of the vehicle's steering wheel and a second grip signal from the driver on the right side of the vehicle's steering wheel are received; or if the first grip signal or the second grip signal is received but no touch signal from the driver on the vehicle's central control screen is received, then it is determined that the driver is gripping the steering wheel.

[0075] If a touchscreen signal is received, but the first grip signal and / or the second grip signal are not received, it is determined that the driver is in the state of touching the central control screen;

[0076] If the first grip signal, first grip signal and touch screen signal are not received within the set time, it is determined that the driver is in a resting state.

[0077] In some optional implementations, the matching relationship between the driver's driving status and the position information of the center armrest is obtained using the following method:

[0078] The first step is to determine multiple driving states of the driver and identify target data for each state. The target data includes the vehicle's driver's seat information, the coordinates of key points on the driver's wrist, and the driver's shoulder joint angle for the corresponding driving state. For example, the driver's driving states are identified as: steering wheel gripping, touchscreen control, and resting.

[0079] The second step is to determine the driver's body part dimensions and, based on the body part dimensions and target data for each driving state, determine the coordinates of the driver's elbow key points for each driving state.

[0080] The vehicle's driver's seat information includes: the position of the driver's seat and the backrest angle of the driver's seat. The driver's body dimensions information includes: the driver's seated shoulder height, seated shoulder width, forearm length, and upper arm length.

[0081] In some alternative implementations, such as Figure 2 As shown, the above operations specifically include the following:

[0082] S301 determines the coordinates of key points on the driver's waist based on the position of the driver's seat in the vehicle.

[0083] S302, determine the coordinates of the driver's neck key points based on the driver's waist key point coordinates, shoulder height in sitting position, and the backrest angle of the driver's seat in the vehicle.

[0084] S303, determine the coordinates of the driver's shoulder key points based on the coordinates of the driver's neck key points and the shoulder width in the sitting position.

[0085] S304. Based on the driver's shoulder key point coordinates, shoulder joint angle, forearm length, upper arm length, and wrist key point coordinates, determine the driver's elbow key point coordinates.

[0086] By performing the above operations, the coordinates of the driver's elbow key points in each driving state can be determined.

[0087] Taking the status of the touch screen as an example, such as Figure 4As shown, the driver's waist key point 401, neck key point 402, shoulder key point 403, elbow key point 404, wrist key point 405, and fingertip key point 406 are related. From the waist key point 401 to the fingertip key point 406, it can be divided into five joint dimensions. The distance from the waist key point 401 to the neck key point 402 is the seated shoulder height. The distance from the neck key point 402 to the shoulder key point 403 is half the seated shoulder width. The distance from the shoulder key point 403 to the elbow key point 404 is the upper arm length. The distance from the elbow key point 404 to the wrist key point 405 is the forearm length. The distance from the wrist key point 405 to the fingertip key point 406 is the hand length.

[0088] The operations described above, from S301 to S304, are based on the position of the driver's seat. After a series of calculations, the coordinates of the driver's elbow key point 404 are obtained.

[0089] For a driver of a specific height, the dimensions of the five joints shown in the figure—seated shoulder height, seated shoulder width, upper arm length, forearm length, and hand length—can be obtained from different percentile human body data for different heights according to GB10000-2023, or from different simulation software (such as CATIA, RAMSIS, etc.).

[0090] The lumbar key point 401 is adjusted to the required position of the driver's seat according to the driver's own body size. The coordinates of the lumbar key point 401 are determined based on the horizontal position and vertical height of the driver's seat. For example, if the driver's seat is an electric seat, the coordinates of the lumbar key point 401 are determined by the driving position, specifically by adjusting the fore-aft, height, and angle of the electric seat. The backrest angle of the driver's seat is equal to the angle of the line connecting the lumbar key point 401 to the neck key point 402, i.e., the driver's upper body tilt angle α. Therefore, the coordinates of the driver's neck key point 402 can be calculated by combining the coordinates of the lumbar key point 401 and the seated shoulder height.

[0091] It is understandable that in each of the multiple driving states, the coordinates of the driver's wrist key point 405 and the driver's shoulder joint angle β are fixed values ​​corresponding to that driving state. For example, in the touch-screen state, the coordinates of the driver's fingertip key point 406 are determined by the position of the screen 407, and the coordinates of the wrist key point 405 can be determined based on the coordinates of the fingertip key point 406 and the hand length. Therefore, the fixed value of the driver's wrist key point 405 coordinates is obtained using the following method:

[0092] Based on the driver's hand length when touching the vehicle's central control screen 407 and the position of the vehicle's central control screen 407, the fixed value of the driver's wrist key point 405 coordinates corresponding to the state of touching the central control screen is determined.

[0093] When the driver operates the central control screen 407, the hand and forearm are basically straight. Therefore, the elbow joint, wrist joint, and fingertip key point 406 are defined on the same straight line. The coordinates of the fingertip key point 406 are determined by the coordinates of the center point of the central control screen 407. The coordinates of the elbow key point 404 can be calculated based on the hand length and forearm length.

[0094] The driver's shoulder joint angle β can be the comfortable angle when the driver's upper arm is outstretched in the current driving state, or it can be the user's subjective evaluation of the comfort angle, or it can be obtained through simulation software. The specific methods for obtaining the driver's comfortable shoulder joint angle in each driving state through simulation software will not be elaborated here.

[0095] In summary, through the operations of S301 to S303, the coordinates of the driver's shoulder key point 403 can be calculated based on the position of the driver's seat, the driver's shoulder height, the backrest angle of the driver's seat, and the driver's shoulder width.

[0096] The position of the elbow key point 404 can be understood as falling on the inflection point of a specific broken line constrained by the positions of the shoulder key point 403 and the wrist key point 405. The constraint conditions are determined by the upper body tilt angle α (i.e., the backrest tilt angle of the driver's seat), the shoulder joint angle β, the forearm length, and the upper arm length. Finally, in the operation of S304, the coordinates of the driver's elbow key point 404 in this driving state are determined based on the coordinates of the driver's shoulder key point 403, shoulder joint angle β, forearm length, upper arm length, and wrist key point 405.

[0097] Similarly, based on the driver's seat information when the vehicle is gripping the steering wheel, the coordinates of the driver's wrist key point 405, shoulder joint angle β, and body dimensions when gripping the steering wheel, the coordinates of the driver's elbow key point 404 are determined. Based on the driver's seat information when the vehicle is resting, the coordinates of the driver's wrist key point 405, shoulder joint angle β, and body dimensions when resting, the coordinates of the driver's elbow key point 404 are determined.

[0098] The third step is to determine the position information of the central armrest based on the coordinates of the key points of the driver's elbow and the thickness of the driver's elbow in each driving state, and to establish a matching relationship between each driving state and the corresponding position information of the central armrest.

[0099] The following describes how the operation S102 is performed in the central handrail control method provided in the embodiments of this application.

[0100] In some alternative implementations, performing S102 includes:

[0101] If it is determined that the driver is gripping the steering wheel, then the target position information of the center armrest is determined as the first position information.

[0102] If it is determined that the driver is touching the central control screen, then the target position information of the center armrest is determined as the second position information.

[0103] If it is determined that the driver is in a resting state, then the target position information of the center armrest is determined as the third position information.

[0104] The purpose of this operation is to determine the target position information of the center armrest to provide comfortable support for the driver's elbow in the current driving state, based on the matching relationship between the driving state and the position information of the center armrest. In other words, the target position of the center armrest is determined, which facilitates the subsequent execution of operations S103 and S104.

[0105] Generally, when the vehicle is not running, the driver is assumed to be in a resting state, and the default position of the center armrest is the third position indicated by the third position information, which is convenient for the driver to place their elbow and rest. If a touch screen signal is received, the center armrest is triggered and moved to the second position indicated by the second position information. If a signal to grip the steering wheel is received, the center armrest is triggered and moved to the first position indicated by the first position information.

[0106] For example, when the driver was previously gripping the steering wheel with both hands to control the vehicle, the center armrest was in its first position, providing comfortable support for the driver's elbows while gripping the steering wheel. In the next moment, the driver's left hand grips the steering wheel, and their right hand moves to operate the vehicle's touchscreen infotainment system. The driver's driving state now switches to touchscreen mode. Based on the displacement of the second and first position information, the center armrest is moved from the first position to the second position, providing comfortable support for the driver's elbows while in touchscreen mode.

[0107] Based on the same inventive concept, this application also provides a central armrest control device, please refer to... Figure 5 , Figure 5 This is a schematic diagram of the central armrest control device in an embodiment of this application. The central armrest control device 500 includes:

[0108] The target driving state determination unit 501 is used to determine the driver's target driving state based on the driver's driving operation signals.

[0109] The target position information determination unit 502 is used to determine the target position information of the central armrest corresponding to the driver's target driving state based on the matching relationship between the driver's driving state and the position information of the central armrest.

[0110] The target displacement determination unit 503 is used to determine the target displacement of the central handrail based on the target position information of the central handrail and the actual position information of the central handrail.

[0111] The movement control unit 504 is used to control the movement of the central handrail according to the target displacement of the central handrail.

[0112] The central armrest control device provided in this application embodiment is used to implement the central armrest control method provided in the above embodiment. It determines the driver's target driving state based on the driver's driving operation signal, determines the target position information of the central armrest corresponding to the current driving state according to the set matching relationship, and determines the displacement of the central armrest from the current actual position to the target position. Based on the displacement, it controls the central armrest to move to the target position corresponding to the target driving state. This enables the central armrest position to adaptively adjust with the change of the driver's arm position, thereby specifically meeting the personalized central armrest position requirements. It can also solve the problems of insufficient support range of traditional central armrests and elbow comfort issues when operating the central control screen at high frequency, while improving the vehicle's intelligence level.

[0113] Based on the same inventive concept, this application also provides a vehicle, such as... Figure 6 As shown, Figure 6 This is a schematic diagram of a vehicle in an embodiment of this application. The vehicle 600 includes the central armrest control device 500 provided in the above embodiment. The central armrest control device 500 can realize the central armrest control method provided in the above embodiment.

[0114] This application also provides a computer-readable storage medium storing a computer program, which, when executed by a processor, causes the computer to perform the method provided in the above embodiments.

[0115] This application also provides a controller, such as... Figure 7 As shown, the controller 700 includes a memory 701, a processor 702, and a computer program 703 stored in the memory 701 and executable on the processor 702. When the processor 702 executes the computer program 703, the controller 700 performs the method provided in the above embodiments.

[0116] The following example uses the vehicle's built-in ECU electronic control unit as an example to illustrate how to use the central armrest control method provided in the embodiment to control the central armrest to provide comfortable support for the driver's elbow when the driver switches from a resting state to a touch screen state.

[0117] The first step is for the ECU to pre-store the initial position information of the driver's seat (i.e., the initial coordinates of the lumbar key point), the position information of the center point of the screen (i.e., the coordinates of the fingertip key point), and the initial position information of the center armrest (i.e., the position information of the center armrest when in a resting state).

[0118] The second step is to read the fore-aft and height positions of the driver's seat, compare them with the designed positions, and calculate the coordinates of the key points of the waist; read the backrest tilt information of the driver's seat, and combine it with the driver's sitting posture and shoulder height to calculate the coordinates of the key points of the neck.

[0119] The third step is to calculate the coordinates of the shoulder key points by combining the coordinates of the neck key points with half the shoulder width of the driver's seated posture.

[0120] The fourth step is to calculate the motion trajectory of point D at the elbow joint based on the positions of the key points on the shoulder and fingertips.

[0121] Fifth step, lock in a comfortable shoulder joint angle, obtain the corresponding comfortable elbow key point position coordinates, take into account the elbow joint thickness, and obtain the position coordinates of the elbow joint point on the support point of the central armrest.

[0122] The sixth step is to compare the desired position coordinates obtained in the fifth step with the initial position of the central handrail stored in the first step to obtain the translation difference.

[0123] Step 7: When the ECU receives a touch signal from the fingertip screen, it drives the central armrest's forward and backward movement motor to move it horizontally, covering its support range to the desired position obtained in step 5.

[0124] It is understood that the controller provided in this application embodiment can adopt the central armrest control method provided in the embodiment. When the driver switches between resting state, touching the central control screen state and gripping the steering wheel state, the controller can control the central armrest to provide comfortable support for the driver's elbow, realize the adaptive adjustment of the central armrest position, and specifically meet the personalized central armrest position needs.
