During travel, users may need to exercise. However, existing vehicles are not equipped with fitness equipment for users to use in the car, which cannot meet users' fitness needs in the car. Summary of the Invention

[0003] The present application provides a seat control method, device, and vehicle. The present application supports users in performing seated leg flexion and extension exercises through the seat leg rest in the vehicle, which can meet the user's in-car fitness needs and can customize the exercise intensity suitable for the user based on the user's physical signs and / or health information, thereby enhancing the user's in-car fitness experience.

[0004] In a first aspect, a seat control method is provided, which is applied to a vehicle, wherein the vehicle seat includes a seat body, a leg rest, a central axis, a damping adjustment device and a fixed structure, wherein the fixed structure is arranged on the leg rest, the central axis is rotatably connected to the seat body, the leg rest is fixedly connected to the central axis, and the damping adjustment device is arranged on the central axis, and the damping adjustment device is used to adjust the resistance encountered by the central axis during rotation; the method includes: when a fitness function of the seat is turned on and the legs of a first user are fixed to the fixed structure, obtaining a target damping; the target damping is the damping set by the first user or the damping recommended based on the first user's physical sign information and / or health information; and controlling the damping adjustment device to output the target damping to adjust the resistance encountered by the central axis during the first user's seated leg flexion and extension exercise using the leg rest.

[0005] Through the above technical solution, the present application obtains a target damping when the seat's fitness function is enabled and a first user's legs are fixed to a fixed structure of a leg rest; the target damping is the damping set by the first user or the damping recommended based on the first user's vital signs and / or health information; and controls a damping adjustment device to output the target damping to adjust the resistance to rotation of the central axis during the first user's seated leg curl and extension exercise using the leg rest. The present application configures a vehicle seat equipped with a leg rest with a fixed structure and a damping adjustment device, allowing a user to perform seated leg curl and extension exercises using the vehicle's seat leg rest; when the seat's fitness function is enabled and the user's legs are fixed to the fixed structure of the leg rest, the user sets the output damping of the damping adjustment device; or, alternatively, the output damping of the damping adjustment device is determined based on the user's vital signs and / or health information; and controls the damping adjustment device to output the target damping to customize the exercise intensity to suit the user, so that when the user performs seated leg curl and extension exercises using the vehicle's seat leg rest, the resistance to the user's legs is neither too great nor too small, thereby meeting the user's in-vehicle fitness needs.

[0006] In conjunction with the first aspect, in certain possible implementations, when the target damping is a damping recommended based on the first user's vital information and / or health information, obtaining the target damping includes: obtaining a first damping from a first mapping relationship based on the first user's vital information; wherein the first mapping relationship includes a plurality of preset vital information and a first preset damping corresponding to each of the plurality of preset vital information; and correcting the first damping based on the health information to obtain the target damping. Based on the above technical solution, by determining the first damping based on the user's vital information, it is possible to ensure that the damping output by the damping adjustment device better matches the user's current physical condition; and, by correcting the first damping based on the health information to obtain the target damping, and determining a suitable exercise intensity in combination with the user's health information, it is possible to avoid increasing the physical burden due to excessive resistance to the user's legs during exercise.

Based on the above-mentioned technical solution, obtaining multiple health information such as the degree of bone development, muscle strength, and age of the user can more comprehensively reflect the user's current health status, and by obtaining the target correction coefficient and correcting the first damping, the corrected target damping can be made consistent with the user's current health status.

Based on the above technical solution, when the leg rest is in different positions, the damping adjustment device is controlled to output different damping values, thereby enhancing the flexibility of the damping adjustment; and, determining the second damping according to the target damping, so that the adjusted damping can still match the physical condition of the first user.

[0011] In combination with the first aspect and the above-mentioned implementation, in some possible implementations, after controlling the damping adjustment device to output the target damping to adjust the resistance to the rotation of the central axis during the first user's seated leg flexion and extension exercise using the leg rest, the method further includes: obtaining the first identity information of the first user and storing the first identity information; when the fitness function of the seat is turned on again and the second user's legs are fixed to the fixed structure, obtaining the second identity information of the second user; using the stored first identity information to verify the second identity information; if the second identity information is verified, executing the step of controlling the damping adjustment device to output the target damping; if the second identity information is not verified, treating the second user as the first user and executing the step of obtaining the target damping. Based on the above technical solution, when a user turns on the fitness function for the first time, the target damping of the user is obtained, and the identity information and damping setting of the user are stored, so that when the same user turns on the fitness function again, the stored damping setting can be quickly called without having to re-obtain the damping suitable for the user.

[0025] The following will clearly and thoroughly describe the technical solutions in this application in conjunction with the accompanying drawings. In the description of the embodiments of this application, unless otherwise specified, " / " means or, for example, A / B can mean A or B: "and / or" in the text is only a description of the association relationship of associated objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, in the description of the embodiments of this application, "multiple" means two or more than two.

[0026] In the following, the terms "first" and "second" are used for descriptive purposes only and should not be understood to imply or suggest relative importance or implicitly indicate the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0027] With the continuous advancement of technology, modern vehicles have evolved into multifunctional mobile living spaces, becoming deeply integrated into people's daily lives. While traveling, users may need to exercise. However, existing vehicles lack in-car fitness equipment, failing to meet these needs.

[0028] Based on the problems existing in the above-mentioned related technologies, the embodiments of the present application provide a method, device, and vehicle for seat control. The present application configures a fixed structure and a damping adjustment device for a vehicle seat equipped with a leg rest, so that a user can perform seated leg curling and extension exercises using the leg rest in the vehicle. When the fitness function of the seat is turned on and the user's legs are fixed to the fixed structure of the leg rest, the user can set the output damping of the damping adjustment device; or, the output damping of the damping adjustment device is determined based on the user's physical information and / or health information; and the damping adjustment device is controlled to output the damping to customize the exercise intensity suitable for the user. When the user performs seated leg curling and extension exercises using the leg rest, the resistance to the user's legs is neither too large nor too small, thereby meeting the user's in-vehicle fitness needs.

[0029] The following is an embodiment of a seat control method provided in an embodiment of the present application.

[0030] Figure 1 A schematic flow chart of a seat control method provided in an embodiment of the present application is shown. The seat control method provided in an embodiment of the present application is applied to a vehicle. Figure 2 FIG1 shows a schematic diagram of the structure of the seat of the vehicle provided in the embodiment of the present application. Figure 2 As shown, the vehicle seat 200 includes a seat body 3, a leg rest 1, a central axis 2, a damping adjustment device 4 and a fixed structure 5. The fixed structure 5 is arranged on the leg rest 1, the central axis 2 is rotatably connected to the seat body 3, the leg rest 1 is fixedly connected to the central axis 2, and the damping adjustment device 4 is arranged on the central axis 2. The damping adjustment device 4 is used to adjust the resistance encountered by the central axis 2 when it rotates.

[0031] The damping adjustment device 4 is, for example, an electromagnetic resistance system, a friction resistance system, an air resistance system, etc. The electromagnetic resistance system is taken as an example to illustrate the working principle of the damping adjustment device 4 in the embodiment of the present application. Figure 2As shown, the electromagnetic resistance system 4 includes a metal flywheel 41 and an electromagnet 42. The flywheel 41 is mounted on the central shaft 2 and is fixedly connected to the central shaft 2. When the central shaft 2 rotates, the flywheel 41 is driven to rotate. The electromagnet 42 is mounted near the flywheel 41, but is not in direct contact with the flywheel 41. When the electromagnet 42 is energized, a magnetic field is generated around the flywheel 41. When the user performs seated leg flexion and extension exercises, the central shaft 2 rotates, driving the flywheel 41 to rotate, and the flywheel 41 cuts the magnetic flux lines. Due to Faraday's law of electromagnetic induction, an electromotive force is generated in the flywheel 41, forming eddy currents. The eddy currents interact with the magnetic field, generating resistance when the flywheel 41 rotates. Since the flywheel 41 is fixedly connected to the central shaft 2, resistance is also generated when the central shaft 2 rotates. Moreover, the resistance generated when the central shaft 2 rotates is equal to the resistance generated when the flywheel 41 rotates. Because the larger the current flowing through the electromagnet 42, the greater the magnetic field strength, the greater the resistance generated. Therefore, by adjusting the magnitude of the current flowing through the electromagnet 42, the magnetic field strength around the flywheel 41 can be changed, and the magnitude of the resistance encountered by the central shaft 2 when rotating can be adjusted. The larger the current magnitude, the greater the resistance; the smaller the current magnitude, the smaller the resistance. It should be understood that in the embodiment of the present application, the resistance encountered by the flywheel 41 when rotating is adjusted by adjusting the magnitude of the current flowing through the electromagnet 42, and the damping output by the damping adjustment device is adjusted. It should be understood that since the leg rest 1 is fixedly connected to the central shaft 2, the resistance encountered by the central shaft 2 when rotating is adjusted, that is, the resistance encountered by the user's legs when the user performs seated leg flexion and extension exercises through the vehicle's seat leg rest is adjusted.

[0032] like Figure 1 As shown, the above seat control method includes the following schemes:

[0033] S110: When the fitness function of the seat is turned on and the legs of the first user are fixed to the fixed structure, a target damping is obtained.

[0034] S120: Controlling the damping adjustment device to output a target damping to adjust the resistance to the rotation of the central axis during the first user's sitting leg flexion and extension exercise using the leg support.

[0035] In an embodiment of the present application, the target damping is the damping set by the first user or the damping recommended based on the first user's vital signs and / or health information. For example, when the chair's fitness function is enabled and the first user's legs are secured to a fixed structure on the chair's leg rest, the first user can perform a seated leg curl exercise using the leg rest. For example, the fixed structure may be a strap, and the first user can secure their legs to the leg rest using the fixed structure so that the leg rest rotates up and down when the first user performs the seated leg curl exercise. Furthermore, the damping output by the seat's damping adjustment device can be adjusted to adjust the resistance to leg rest rotation, thereby simulating a weight-bearing state for the legs when the first user performs the seated leg curl exercise, thereby enhancing the effectiveness of the exercise. Therefore, in an embodiment of the present application, the output damping of the damping adjustment device can be set by the user; alternatively, the output damping of the damping adjustment device can be determined based on the user's vital signs and / or health information.

[0036] It should be understood that when the first user performs the seated leg curling and extension exercise with the leg rest, the first user's legs need to overcome a certain resistance to complete the action, and the amount of resistance that the first user's legs can overcome depends on the first user's physical condition. The physical condition can be reflected by vital information and / or health information. Therefore, the amount of resistance that the first user's legs can overcome when performing the seated leg curling and extension exercise can be determined by the first user's vital information and / or health information. Moreover, since the embodiment of the present application adjusts the resistance encountered by the leg rest when rotating by adjusting the damping output by the damping adjustment device of the seat, the target damping output by the damping adjustment device can be determined based on the first user's vital information and / or health information, and then the target damping can be output by the damping adjustment device to apply a resistance that matches the first user's physical condition to the first user's legs when the first user performs the seated leg curling and extension exercise.

[0037] Through the above technical solution, the present application obtains a target damping when the seat's fitness function is enabled and a first user's legs are fixed to a fixed structure of a leg rest; the target damping is the damping set by the first user or the damping recommended based on the first user's vital signs and / or health information; and controls a damping adjustment device to output the target damping to adjust the resistance to rotation of the central axis during the first user's seated leg curl and extension exercise using the leg rest. The present application configures a vehicle seat equipped with a leg rest with a fixed structure and a damping adjustment device, allowing a user to perform seated leg curl and extension exercises using the vehicle's seat leg rest; when the seat's fitness function is enabled and the user's legs are fixed to the fixed structure of the leg rest, the user sets the output damping of the damping adjustment device; or, alternatively, the output damping of the damping adjustment device is determined based on the user's vital signs and / or health information; and controls the damping adjustment device to output the target damping to customize the exercise intensity to suit the user, so that when the user performs seated leg curl and extension exercises using the vehicle's seat leg rest, the resistance to the user's legs is neither too great nor too small, thereby meeting the user's in-vehicle fitness needs.

[0038] In one possible implementation, when the target damping is a damping recommended based on the first user's vital sign information and / or health information, obtaining the target damping includes:

[0039] Obtaining a first damping from a first mapping relationship according to the vital sign information of the first user;

[0040] The first damping is modified according to the health information to obtain the target damping.

[0041] It should be understood that the first user's physical information determines the basic resistance that the first user's legs can overcome when the first user performs a seated leg flexion and extension exercise. Exemplarily, the first user's physical information includes at least one of weight, height, and gender. Therefore, in an embodiment of the present application, the first damping is searched from the first mapping relationship based on the first user's physical information. The first damping is the damping corresponding to the basic resistance that the first user's legs can overcome. The first mapping relationship includes a plurality of preset physical information and a first preset damping corresponding to each of the plurality of preset physical information. The plurality of preset physical information is respectively the physical information of a plurality of different users.

[0042] For example, assuming that the physical sign information of the first user is weight, the weight range is divided into multiple preset weight intervals, each preset weight interval corresponds to a first preset damping, and the first mapping relationship between the preset weight intervals and the first preset damping is shown in Table 1.

[0043] Table 1

[0044] Preset weight range\kg First preset damping (kg·m / s) (50，60] 10 (60，70] 15 (70，80] 20 ...... ......

[0045] Exemplarily, the first damping is found according to the weight of the first user from the first mapping relationship shown in Table 1. For example, the first user is user A, and user A weighs 55 kg, so the first damping corresponding to user A is 10 kg·m / s.

[0046] It should be understood that the physical condition of the first user is comprehensively reflected by the vital information and health information. Therefore, when determining the output damping of the damping adjustment device, it is necessary to comprehensively consider the vital information and health information of the first user. The basic damping determined only based on the vital information of the first user cannot accurately match the physical condition of the first user. Therefore, the setting of the output damping should take into account the health information of the first user, that is, the first damping is corrected by the health information to obtain the target damping. Since the setting of the target damping comprehensively considers the vital information and health information of the first user; therefore, when the damping adjustment device outputs the target damping, the resistance applied to the legs of the first user can accurately match the physical condition of the first user, ensuring that the intensity of the first user's seated leg flexion and extension exercise using the leg rest is neither too large nor too small.

[0047] Based on the above technical solution, by determining the first damping according to the vital signs information, it can ensure that the damping output by the damping adjustment device better matches the user's current physical condition; and, the first damping is corrected according to the health information to obtain the target damping, and the appropriate exercise intensity is determined in combination with the user's health information, which can avoid increasing the body burden due to excessive resistance on the user's legs during exercise.

[0048] In one possible implementation, the health information includes at least one of skeletal development, muscle strength, and age; and the step of modifying the first damping according to the health information to obtain the target damping includes:

[0049] Obtaining a correction coefficient corresponding to at least one of the degree of bone development, muscle strength, and age;

[0050] Performing a weighted operation on the correction coefficient corresponding to at least one of the degree of bone development, muscle strength, and age to obtain a target correction coefficient;

[0051] The product of the target correction coefficient and the first damping is determined to obtain the target damping.

[0052] It should be understood that health information such as bone development level, muscle strength, age and medical history can reflect the physical health status of the first user. Each piece of health information has a corresponding correction coefficient, which is used to quantify the impact of the health information on the damping setting. The value of the correction coefficient is usually between 0 and 2. The approximate range of the correction coefficient can be determined according to the different characteristics of the health information. For example, for the degree of bone development, the correction coefficient can be set to between 0.8 and 1.2; for muscle strength, the correction coefficient can be set to between 0.7 and 1.3; for age, the correction coefficient can be set to between 0.5 and 1.5.

[0053] For example, different health information has different degrees of influence on the damping value. Therefore, when determining the target damping, the weight of each health information is determined according to its importance. Through weighted calculation, the factors that have a greater impact on the damping setting can be highlighted, so that the final result is more reasonable. The weight corresponding to the health information that has a greater impact on the damping setting is larger; for example, the degree of bone development and muscle strength have a greater impact on the first user's athletic ability, and the weights corresponding to the degree of bone development and muscle strength can be set to 0.5 and 0.4 respectively. The weight corresponding to the health information that has a smaller impact on the damping setting is smaller; for example, the disease history has a smaller impact on the first user's athletic ability, and the weight corresponding to the disease history can be set to 0.1.

[0054] For example, after obtaining the correction coefficients and weights corresponding to health information such as skeletal development, muscle strength, and age, a weighted calculation is performed to obtain a target correction coefficient. A target correction coefficient greater than 1 indicates good health, and the damping can be appropriately increased based on the first damping to increase exercise intensity. A target correction coefficient less than 1 indicates poor health, and the damping needs to be appropriately reduced based on the first damping to reduce exercise intensity and avoid excessive load.

[0055] For example, assume that health information includes skeletal development, muscle strength, and age. The first user is user A. For user A, the first damping is 10 kg·m / s. The correction coefficient for skeletal development is 1.2, with a weight of 0.4. The correction coefficient for muscle strength is 1.1, with a weight of 0.3. The correction coefficient for age is 0.9, with a weight of 0.3. Therefore, the target correction coefficient = (1.2 × 0.4) + (1.1 × 0.3) + (0.9 × 0.3) = 1.08. Target damping = 10 kg·m / s × 1.08 = 10.8 kg·m / s.

[0056] Based on the above technical solution, obtaining multiple health information of the user, such as the degree of bone development, muscle strength and age, can more comprehensively reflect the user's current health status, and by obtaining the target correction coefficient and correcting the first damping, the corrected target damping can be made consistent with the user's current health status.

[0057] In one possible implementation, when the target damping is a damping recommended based on the first user's vital sign information and / or health information, obtaining the target damping includes:

[0058] The target damping is obtained from the second mapping relationship according to the vital sign information and health information of the first user.

[0059] For example, in an embodiment of the present application, the target damping can be determined directly from a second mapping relationship based on the first user's vital sign information and health information. The second mapping relationship includes multiple preset information groups and second preset damping corresponding to each of the multiple preset information groups; wherein the preset information groups include preset vital sign information and preset health information.

[0060] For example, assuming that the first user's physical information includes height and weight, and their health information includes skeletal development and muscle strength, each preset information group contains information on height, weight, skeletal development, and muscle strength. Each preset information group corresponds to a second preset damping. The second mapping relationship between the preset information groups and the second preset damping is shown in Table 2.

[0061] Table 2

[0062]

[0063] Exemplarily, the target damping is found from the second mapping relationship shown in Table 2 based on the first user's vital signs and health information. For example, if the first user is user B, who is 160 cm tall, weighs 60 kg, has poor bone development, and weak muscle strength, then the target damping corresponding to user A is 10 kg·m / s.

[0064] Based on the above technical solution, by determining the target damping according to the user's physical information and health information, the target damping suitable for the user can be quickly determined, and the damping output by the damping adjustment device can be ensured to better match the user's current physical condition.

[0065] In one possible implementation, after controlling the damping adjustment device to output the target damping to adjust the resistance to rotation of the central axis during the first user's seated leg flexion and extension exercise using the leg support, the method further includes:

[0066] Get the number of reps for the seated leg extension exercise;

[0067] Show the number of actions.

[0068] For example, Figure 3 A schematic diagram of an application scenario of a leg support position change provided by an embodiment of the present application is shown. Figure 3 As shown, the first user's legs drive the leg rest from the first position to the second position, and then from the second position to the first position, which is a sitting leg flexion and extension movement, wherein the second position is higher than the first position. The first position is the initial position of the leg rest.

[0069] It should be understood that when the first user begins the seated leg curl exercise, a count counter is started, initialized to zero, and begins recording the number of times the first user performs the seated leg curl exercise. Each time the sensor detects that the leg rest changes from a first position to a second position and then from the second position back to the first position, the count counter increments by one. The sensor used to detect the position change of the leg rest may include, for example, a position sensor, an angle sensor, or other type of sensor, which is not limited in this application.

[0070] For example, after the number of times a sitting leg extension exercise is performed is obtained through a times counter, the number of times is displayed to the first user. For example, the number of times the first user performs the exercise can be displayed in real time during the exercise, or the total count obtained by the times counter can be displayed after the first user finishes the exercise, so that the first user can understand their exercise progress. The display method can be through a display screen, voice broadcast, mobile phone application, or other visual method, which is not limited in this application.

[0071] Based on the above technical solution, by recording and displaying the number of movements when the user performs seated leg flexion and extension exercises, exercise feedback can be provided to the user, which helps the user to understand his or her exercise progress.

[0072] In one possible implementation, after controlling the damping adjustment device to output the target damping to adjust the resistance to rotation of the central axis during the first user's seated leg flexion and extension exercise using the leg support, the method further includes:

[0073] Obtaining a resistance adjustment coefficient range from a third mapping relationship according to target damping;

[0074] determining a second damping according to any resistance adjustment coefficient in the resistance adjustment coefficient range and the target damping;

[0075] When the leg of the first user drives the leg support to reach the second position, controlling the damping adjustment device to output the second damping;

[0076] When the leg of the first user drives the leg rest to reach the first position, the damping adjustment device is controlled to output the target damping.

[0077] Illustratively, the embodiment of the present application supports adjusting the output damping of the damping adjustment device during the first user's sitting leg flexion and extension exercise using a leg rest, so as to more flexibly adapt to the needs of different first users.

[0078] It should be understood that the seated leg flexion and extension action includes the process of lifting the legs upward (the legs of the first user drive the leg support from the first position to the second position) and the process of pressing the legs downward (the legs of the first user drive the leg support from the second position to the first position). The legs of the first user drive the leg support to reach the second position, indicating that the first user has completed the action of lifting the legs upward. At this time, the damping adjustment device can be controlled to output the second damping according to the needs of the user to adjust the resistance applied to the legs of the first user in the process of the first user pressing the legs downward. Exemplarily, the second damping can be greater than the target damping, that is, the damping is increased in the process of the first user pressing the legs downward to increase the exercise intensity; or, the second damping can be less than the target damping, that is, the damping is reduced in the process of the first user pressing the legs downward to reduce the exercise intensity and avoid excessive load; or, the second damping can be equal to the target damping, that is, the damping remains unchanged in the process of the first user pressing the legs downward to maintain the current exercise intensity.

[0079] To better match the damping adjustment to the first user's physical condition, in this embodiment of the present application, the second damping is determined based on the target damping. Specifically, the resistance adjustment coefficient range is searched from a third mapping relationship based on the first user's target damping. The third mapping relationship includes multiple third preset damping values ​​and corresponding preset ranges for each of the multiple third preset damping values.

[0080] Exemplarily, a third mapping relationship between the third preset damping and the preset intervals is shown in Table 3. The third preset damping is divided into a plurality of preset damping intervals, and the resistance adjustment coefficient range is divided into a plurality of preset intervals. Each preset damping interval corresponds to a preset interval of the resistance adjustment coefficient.

[0081] Table 3

[0082]

[0083]

[0084] When the resistance adjustment coefficient is less than 1, the second damping determined based on the resistance adjustment coefficient and the target damping is less than the target damping. When the resistance adjustment coefficient is greater than 1, the second damping determined based on the resistance adjustment coefficient and the target damping is greater than the target damping. When the resistance adjustment coefficient is equal to 1, the second damping determined based on the resistance adjustment coefficient and the target damping is equal to the target damping. For example, assume that the second damping is determined based on the product of the resistance adjustment coefficient and the target damping. The first user is user A. For user A, the target damping is 10.8 kg·m / s. The third preset damping corresponding to user A is in the interval (10, 15]. The preset interval of the resistance adjustment coefficient corresponding to user A is (0.7, 0.9]. Taking the resistance adjustment coefficient as 0.8, the second damping = 10.8 kg·m / s × 0.8 = 8.64 kg·m / s. That is, when the legs of user A drive the leg rest to reach the second position, the damping value output by the control damping adjustment device is 8.64 kg·m / s. When the legs of user A drive the leg rest to reach the first position again, the damping value output by the control damping adjustment device is 10.8 kg·m / s.

[0085] Based on the above technical solution, when the leg rest is in different positions, the damping adjustment device is controlled to output different damping values, thereby enhancing the flexibility of the damping adjustment; and the second damping is determined according to the target damping, so that the adjusted damping can still match the physical state of the first user.

[0086] In one possible implementation, after controlling the damping adjustment device to output the target damping to adjust the resistance to rotation of the central axis during the first user's seated leg flexion and extension exercise using the leg support, the method further includes:

[0087] Obtaining first identity information of a first user and storing the first identity information;

[0088] When the fitness function of the seat is turned on again and the legs of the second user are fixed to the fixed structure, obtaining the second identity information of the second user;

[0089] Verifying the second identity information using the stored first identity information;

[0090] If the second identity information is verified, executing the step of controlling the damping adjustment device to output the target damping;

[0091] If the second identity information verification fails, the second user is treated as the first user and the step of obtaining the target damping is performed.

[0092] It should be understood that the first identity information of the first user includes, for example, a facial image and / or iris image of the first user. The facial image and / or iris image of the first user is captured by an in-vehicle camera as the first identity information of the first user. The first identity information and the target damping of the first user are then stored in the vehicle database. When the fitness function of the seat is reactivated and the second user's legs are secured to the fixed structure, the second identity information of the second user is obtained. Based on the second identity information, the database is searched for the first identity information that is identical to the second identity information. If the database contains the first identity information that is identical to the second identity information, it indicates that the second identity information has been verified successfully and the second user is the same user as the first user. The target damping corresponding to the first identity information that is identical to the second identity information is used as the target damping of the second user, and the damping adjustment device is controlled to output the target damping. If the database does not contain the first identity information that is identical to the second identity information, it indicates that the second identity information has not been verified successfully and the second user is not the same user as the first user. During execution of the method, the second user is treated as the first user, and the steps from obtaining the target damping to controlling the damping adjustment device to output the target damping are performed. After determining the target damping corresponding to the second user, the second identity information and the target damping corresponding to the second user are stored in a database of the vehicle.

[0093] Based on the above technical solution, when a user turns on the fitness function for the first time, the user's target damping is obtained, and the user's identity information and damping settings are stored, so that when the same user turns on the fitness function again, the stored damping settings can be quickly called without having to re-acquire the damping suitable for the user.

[0094] In one possible implementation, after controlling the damping adjustment device to output the target damping to adjust the resistance to rotation of the central axis during the first user's seated leg flexion and extension exercise using the leg support, the method further includes:

[0095] According to the duration and / or target frequency of the seated leg extension exercise performed by the first user using the leg rest, environmental parameters in the vehicle cabin are adjusted to simulate a fitness environment.

[0096] The target frequency includes at least one of the breathing frequency, heart rate, and frequency of the leg support driven by the first user's legs to rotate.

[0097] For example, by monitoring the duration and / or target frequency of the first user performing the seated leg curl exercise with the leg rest, the first user's exercise intensity and real-time physical condition can be understood, and then the environmental parameters in the cabin can be adjusted to simulate an environment similar to a gym or outdoor fitness venue, thereby enhancing the first user's exercise experience and effect. The environmental parameters include at least one of the brightness of the ambient light in the cabin, the flashing frequency of the ambient light, the volume of the multimedia, and the content played by the multimedia. For example, the flashing frequency of the ambient light in the cabin is adjusted according to the breathing frequency of the first user, so that the ambient light flashes according to the breathing frequency of the first user to create an atmosphere conducive to exercise. In addition, the content played by the multimedia in the cabin is adjusted according to the duration of the first user's exercise, such as playing an instructional video of the seated leg curl exercise when the first user starts exercising, to help the first user master the correct exercise posture and improve the first user's exercise efficiency.

[0098] Based on the above technical solution, the environmental parameters in the cabin are adjusted according to the user's exercise duration and / or target frequency, which can simulate the atmosphere of a gym and enhance the user's exercise experience.

[0099] The above technical solution configures a vehicle seat equipped with a leg rest with a fixed structure and a damping adjustment device, allowing users to perform seated leg curls and extensions using the leg rest. When the seat's fitness function is enabled and the user's legs are secured to the leg rest's fixed structure, the user can set the damping output of the damping adjustment device. Alternatively, the damping output of the damping adjustment device is determined based on the user's vital signs and / or health information. The damping output of the damping adjustment device is controlled to accurately match the user's physical condition when performing seated leg curls and extensions using the vehicle's leg rest, ensuring the resistance applied to the user's legs is neither too high nor too low. This satisfies the user's in-vehicle fitness needs. Furthermore, the damping can be flexibly adjusted during the seated leg curl exercise. Furthermore, the number of reps performed during the exercise is recorded and displayed, providing user feedback. The vehicle's memory function stores the current user's identity information and damping settings, allowing the user to quickly recall the stored damping settings when the fitness function is enabled again. When the user performs seated leg curling and extension exercises, the environmental parameters in the cabin are adjusted to simulate a fitness environment and enhance the user's fitness experience in the car.
