Description

Technical Field

[0002] In today's fast-paced life, people often sit in the office for a long time and have no time to go to the gym for fitness exercises. In this context, more and more vehicles are equipped with fitness devices so that people can do fitness exercises in the car, thus solving the problem of not having time for fitness exercises. At the same time, when doing fitness exercises, people often pay attention to the amount of fat they burn during exercise to determine whether their exercise is up to standard. Therefore, it is very important to detect the amount of fat burned during fitness exercises.

[0003] In the related art, a user can wear a smart watch. When doing fitness exercises, the smart watch can detect the user's exercise data during the exercise, such as heart rate, speed and other data. Then, the user's fat burning amount is calculated based on the user's height, weight, gender and exercise data, so that the user can know the amount of fat burned during the fitness exercise.

[0004] However, in the above method, the user needs to wear a smart watch to know the amount of fat burned during exercise, that is, the above method must rely on a smart watch to get the amount of fat burned.

[0068] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0069] It should be understood that the "multiple" mentioned in this application refers to two or more. In the description of this application, unless otherwise specified, " / " means or, for example, A / B can mean A or B; "and / or" in this article 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 order to facilitate the clear description of the technical solution of this application, the words "first" and "second" are used to distinguish between the same items or similar items with basically the same functions and effects. Those skilled in the art can understand that the words "first" and "second" do not limit the quantity and execution order, and the words "first" and "second" do not limit them to be different.

[0070] The application scenario of the embodiment of the present application is first described.

[0071] At present, when doing fitness exercises, the user's fat burning amount is measured by obtaining exercise data through a smart watch. When measuring fat burning amount through a smart watch, it is necessary to set the user's height, weight, gender, etc. During the user's exercise, the inertial sensor (accelerometer, directional gyroscope, etc.) in the smart watch can first measure the user's exercise data (heart rate, speed, height and other data), and then the smart watch can determine the amount of fat burned during the fitness exercise based on these data.

[0072] However, when doing fitness exercises with a smartwatch, a lot of exercise data needs to be measured. Especially when doing fitness exercises in a vehicle, the user's body does not change much in three-dimensional space. Then the exercise data measured by the smartwatch will be different from the user's actual exercise data, which will lead to inaccurate fat burning. In addition, the above method must rely on a smartwatch to determine the amount of fat burned. If the user does not like to wear a smartwatch, he will not be able to know the amount of fat burned during exercise, which reduces the user experience.

[0073] To this end, an embodiment of the present application provides a method for determining the amount of fat burned, which can be applied to the scenario of performing fitness exercises in a vehicle. Specifically, the fitness device in the vehicle includes a generator, a transmission member, and a stretching member. When a passenger performs fitness exercises in the vehicle, the stretching member can be pulled, and when the stretching member is stretched, the transmission member can be rotated, and when the transmission member rotates, the generator can be driven to rotate, so that the generator generates electricity. Therefore, when a passenger performs fitness exercises in the vehicle, the fitness device will convert the amount of fat consumed into electrical energy and the friction loss energy of the transmission member. Based on this, when a passenger performs fitness exercises in the vehicle, the amount of fat burned by the passenger during the fitness process can be determined based on the power generation of the fitness device and the friction loss energy of the transmission member of the fitness device. In this way, the amount of fat burned by the passenger during the fitness process can be determined more conveniently without the need to wear a smart watch, thereby improving the user experience.

[0074] Before describing in detail the method provided in the embodiment of the present application, the fitness device involved in the present application is described first. Figure 1 It is a structural schematic diagram of a fitness device in a vehicle provided by the present application.

[0075] In a possible implementation, the fitness device includes a stretching member, a transmission member, and a generator, wherein the stretching member is connected to the transmission member, and the transmission member is connected to the generator. The connection method between the stretching member and the transmission member and the connection method between the generator and the transmission member are not limited in the embodiment of the present application. When the stretching member is stretched, the transmission member rotates, and when the transmission member rotates, the generator is driven to rotate.

[0076] For example, Figure 1 As shown, the fitness device includes a stretching member 1, a transmission member 2 and an engine 3. When the stretching member 1 is stretched, a chain 4 between the stretching member and the transmission member can pull the transmission member 2 to rotate, thereby driving the generator to rotate and generate a certain amount of electricity.

[0077] In a possible implementation, the fitness device further includes a front wheel and a rear wheel, and the front wheel and the rear wheel enable the fitness device to move forward or backward.

[0078] For example, Figure 2Schematic diagram of a fitness device provided in an embodiment of the present application. Figure 2 As shown, Figure 2 The middle fitness device is equipped with front wheels 5 and rear wheels 6, which can enable the fitness device to move forward or backward, so that all passengers in the vehicle can use the fitness device and obtain certain fitness effects.

[0079] The method for determining the amount of fat burned provided in the embodiments of the present application is explained in detail below.

[0080] Figure 3 Flow chart of a method for determining the amount of fat burned provided by an embodiment of the present application. The method can be applied to the HUT (Head Unit, vehicle multimedia host) of a vehicle. Figure 3 , the method comprises the following steps.

[0081] 301: In response to a triggering operation on a fitness device in a vehicle, the power generation of a generator in the fitness device is obtained, wherein the fitness device includes a generator, a transmission member and a tension member, the tension member is connected to the transmission member, the generator is connected to the transmission member, when the tension member is stretched, the transmission member rotates, and when the transmission member rotates, the generator is driven to rotate.

[0082] Among them, the triggering operation of the fitness device in the vehicle can be achieved by the passenger. The passenger can achieve the triggering operation by clicking, sliding, voice, gesture, knocking sound, body sensation, etc., which is not limited in the embodiments of the present application. As an example, when the microphone in the vehicle receives the voice command of "turn on the fitness device" output by the passenger, the HUT can control the fitness device to turn on, thereby achieving the triggering operation of the fitness device in the vehicle. As another example, when the camera in the vehicle receives the gesture command made by the passenger, the HUT can control the fitness device to turn on, thereby achieving the triggering operation of the fitness device in the vehicle.

[0083] The fitness device is a device installed in a vehicle for a passenger to perform fitness exercises. When a passenger wants to perform fitness exercises, the fitness device can be triggered.

[0084] For example, the fitness device can be the above-mentioned Figure 1 The fitness device shown in the figure comprises a stretching member, a transmission member and a generator. After the passenger triggers the fitness device, the stretching member 1 of the fitness device can be pulled to perform fitness exercises. When the stretching member 1 is stretched, the chain 4 can pull the transmission member 2 to rotate, and when the transmission member 2 rotates, the chain 4 can pull the engine 3 to rotate, thereby causing the generator 3 to generate electricity.

[0085] Thus, when the passenger uses the fitness device to exercise, the fitness device converts mechanical energy into electrical energy. In this case, the power generation of the generator can be obtained, so that the fat burning amount of the passenger during the fitness process can be determined based on the power generation of the generator.

[0086] The generator in the fitness device can be connected to a component battery in the vehicle, so that the electric energy generated by the generator can charge the battery.

[0087] Optionally, the power generation of the generator in the fitness device may be detected by the MCU (Motor Control Unit) of the vehicle, and then the acquired power generation is sent to the HUT, so that the HUT acquires the power generation of the generator in the fitness device.

[0088] 302: Determine the amount of fat burned by the passenger during the fitness process based on the power generation of the generator and the friction coefficient of the transmission component of the fitness device.

[0089] Optionally, the friction coefficient of the transmission member of the fitness device can be set by a technician, and can be set according to the resistance of the transmission member of the fitness device. The greater the resistance, the greater the friction coefficient can be set, and the smaller the resistance, the smaller the friction coefficient can be set.

[0090] When a passenger performs fitness exercises in a vehicle, the fat consumed is converted into electrical energy and friction loss energy of the transmission parts. Therefore, the amount of fat burned by the passenger during fitness exercises can be determined based on the power generation of the generator and the friction coefficient of the transmission parts of the fitness device.

[0091] In this case, passengers no longer need to wear smart watches when doing fitness exercises in the vehicle. The structural characteristics of the fitness device can more conveniently determine the amount of fat burned by the passengers during the fitness process, thereby improving the user experience.

[0092] Specifically, the operation of 302 may be: based on the power generation of the generator and the friction coefficient of the transmission member of the fitness device, determine the fat burning amount of the passenger during the fitness process by the following formula 1.

[0093] C*η+W=C (1)

[0094] Among them, C is the amount of fat burned by the passenger during the fitness process, η is the friction coefficient of the transmission parts of the fitness device, C*η is the friction loss energy on the transmission parts, and W is the power generation of the generator of the fitness device during the passenger's fitness process.

[0095] Since the amount of fat burned by the passengers is converted into electrical energy and friction loss energy of the transmission parts, in this case the amount of fat burned by the passengers during the fitness process is determined based on this energy conservation relationship, so that the amount of fat burned by the passengers during the fitness process can be determined conveniently and accurately.

[0096] Optionally, the HUT can determine the amount of fat burned by the passenger during the fitness process at intervals of a first preset time. Furthermore, the amount of fat burned can be reported through an audio playback device of the vehicle, such as an AMP (Power Amplifier), so that the passenger can know his or her own amount of fat burned in real time during the fitness process, thereby improving the user experience.

[0097] The first preset time length can be set in advance, and the first preset time length can be set by the passenger as needed. For example, the first preset time length can be set to 5 minutes, or the first preset time length can be set to 10 minutes.

[0098] Optionally, the fitness device may include a plurality of stretching members, so that a plurality of passengers in the vehicle can pull the stretching members of the fitness device to perform fitness exercises, thereby satisfying the needs of multiple people to perform fitness exercises at the same time.

[0099] In this case, the operation of 302 may be: respectively obtaining the number of stretching times of the multiple stretching parts used by multiple passengers in the vehicle; and determining the amount of fat burned by each passenger during fitness based on the power generation of the generator, the friction coefficient of the transmission parts of the fitness device, and the number of stretching times of the multiple stretching parts.

[0100] In this case, when there are multiple passengers in the vehicle using the fitness device at the same time, the amount of fat burned by each passenger during the fitness process can be determined, thereby improving the user experience.

[0101] Optionally, the fitness device may include a plurality of counters, which correspond to the plurality of stretching members one by one. When a passenger in the vehicle stretches a stretching member, the counter corresponding to the stretching member can count the number of times the stretching member is stretched. In this way, the plurality of counters can count the number of times the passenger in the vehicle uses the plurality of stretching members.

[0102] Optionally, the number of stretching times using the multiple stretching members in the vehicle may also be determined through video information captured by a camera in the vehicle.

[0103] In this case, the video information can be identified to identify multiple passengers using the multiple stretching members in the video information, and the number of stretching times each passenger uses the corresponding stretching members can be counted to obtain the number of stretching times the passengers in the vehicle use the multiple stretching members.

[0104] Optionally, the camera in the vehicle may be a camera with a DMS (Driver Monitor System) or an OMS (Occupant Monitoring System). In this case, after the camera captures the video information in the vehicle, it can directly determine the number of times the passengers in the vehicle have stretched using the multiple stretching members. In this way, the efficiency of determining the number of stretching times is improved.

[0105] Among them, based on the power generation of the generator, the friction coefficient of the transmission parts of the fitness device and the number of stretching times of the multiple stretching parts, the operation of determining the amount of fat burned by each passenger during the fitness process can be: based on the power generation of the generator and the friction coefficient of the transmission parts of the fitness device, determining the total energy consumed when stretching the multiple stretching parts; based on the number of stretching times of the multiple stretching parts, determining the total number of stretching times of the multiple passengers; dividing the total energy by the total number of stretching times to obtain a single energy; for any one of the multiple passengers, multiplying the single energy by the number of stretching times of the corresponding stretching part used by this passenger to obtain the amount of fat burned by this passenger during the fitness process.

[0106] Total energy is the total amount of fat burned by passengers using multiple stretching devices during fitness. Total stretching times is the total number of times multiple passengers in the vehicle stretch the multiple stretching devices. Single energy is the energy consumed when a passenger stretches a stretching device once, that is, the amount of fat burned when stretching a stretching device once.

[0107] In this case, when multiple passengers stretch multiple stretching pieces together, the total amount of fat consumed by these multiple passengers is converted into the electrical energy generated by the generator and the friction loss energy on the transmission parts. Based on this, the total energy consumed by multiple passengers when they stretch multiple stretching pieces together can be determined first, and then the amount of fat burned by each passenger during the fitness process can be determined based on the total energy and the number of times each passenger stretches the corresponding stretching piece.

[0108] For example, the fitness device includes three stretching pieces, and there are three passengers in the vehicle using the three stretching pieces. The total energy of the three passengers when stretching the three stretching pieces is 60, wherein the first passenger stretches the first stretching piece once, the second passenger stretches the second stretching piece twice, and the third passenger stretches the third stretching piece three times. It can be calculated that the total number of stretching times of the three passengers stretching the three stretching pieces is 6. Then the total energy (60) is divided by the total number of stretching times (6) to obtain a single energy of 10, that is, the fat burning amount of each passenger stretching the stretching piece is 10. Finally, for the first passenger, the single energy (10) is multiplied by the number of stretching times (1) of the first passenger to obtain a fat burning amount of 10 for the first passenger. For the second passenger, the single energy (10) is multiplied by the number of stretching times (2) of the second passenger to obtain a fat burning amount of 20 for the second passenger. For the third passenger, the single energy (10) is multiplied by the number of stretching times (3) of the third passenger to obtain a fat burning amount of 30 for the third passenger.

[0109] In this way, when multiple passengers in a vehicle use the fitness device, the amount of fat burned by each passenger during the fitness process can be accurately determined, thereby improving the user experience.

[0110] Specifically, based on the power generation of the generator and the friction coefficient of the transmission parts of the fitness device, the operation of determining the total energy consumed when stretching the multiple stretching parts can be: based on the power generation of the generator and the friction coefficient of the transmission parts of the fitness device, the total energy consumed when stretching the multiple stretching parts is determined by the following formula 2.

[0111] C 总 *η+W=C 总 (2)

[0112] Among them, C 总 =C1+C2+......C n , C 总 is the total energy consumed by the passenger when stretching the multiple stretching parts, C1 is the fat burning amount of the first passenger in the vehicle when stretching the stretching parts of the fitness device, C2 is the fat burning amount of the second passenger in the vehicle when stretching the stretching parts of the fitness device, and C n is the amount of fat burned by the nth passenger in the vehicle when stretching the stretching part of the fitness device, where n is a positive integer. 总 *η is the total friction loss energy of the transmission parts when the passenger stretches the multiple stretching parts.

[0113] For example, the friction coefficient of the transmission part of the fitness device is 0.2. During the fitness exercise of the three passengers, the power generation of the fitness device is 5. Based on the power generation of the generator and the friction coefficient of the transmission part of the fitness device, the formula C总 *0.2+5=C 总 It was determined that the total energy consumed in stretching the plurality of stretching members was 6.25.

[0114] Optionally, the friction coefficient of the transmission member of the fitness device may be associated with the gear position of the fitness device, that is, the friction coefficient of the transmission member of the fitness device corresponds to the gear position of the fitness device, and the friction coefficient of the transmission member of the fitness device is different in different gear positions.

[0115] For example, the correlation between the friction coefficient of the transmission member of the fitness device and the gear position of the fitness device is shown in Table 1. Table 1 includes multiple gear positions and multiple friction coefficients. Assuming that the gear position of the fitness device is 2, the friction coefficient of its transmission member is 0.3.

[0116] Table 1

[0117] Gear Friction coefficient 1 0.2 2 0.3 3 0.4 …… ……

[0118] The embodiment of the present application only uses Table 1 above as an example to illustrate the correlation between the friction coefficient of the transmission part of the fitness device and the gear position of the fitness device, and does not constitute a limitation to the present application.

[0119] In this case, the operation of 302 may be: determining the amount of fat burned by the passenger during the fitness process based on the power generation of the generator and the friction coefficient of the transmission member of the fitness device in the current gear.

[0120] The friction coefficient of the transmission part of the fitness device is different in different gears. In this case, based on the power generation of the generator and the friction coefficient of the transmission part of the fitness device in the current gear, a more accurate fat burning amount can be determined, thereby improving the user experience.

[0121] It is worth noting that before determining the amount of fat burned by the passenger during the fitness process, the current gear of the fitness device must be obtained, and the friction coefficient of the transmission member of the fitness device in the current gear is determined based on the current gear.

[0122] Optionally, the current gear of the fitness device can be obtained through the vehicle's TCU (Transmission Control Unit), and then the TCU sends the current gear of the fitness device to the HUT, so that the HUT obtains the current gear of the fitness device, thereby determining the friction coefficient of the transmission part of the fitness device in the current gear.

[0123] Specifically, based on the power generation of the generator and the friction coefficient of the transmission member of the fitness device in the current gear, the implementation method of determining the amount of fat burned by the passenger during the fitness process may include the following two possible situations.

[0124] When only one passenger uses the fitness device, the power generation coefficient of the generator is determined based on the friction coefficient of the transmission member of the fitness device in the current gear position; the power generation of the generator is divided by the power generation coefficient to obtain the fat burning amount of the passenger during the fitness process. That is, the fat burning amount of the passenger during the fitness process can be determined by the following formula 3. Among them, the sum of the power generation coefficient and the friction coefficient is the target value, and the target value in the following formula 3 is 1.

[0126] η i is the friction coefficient of the transmission member of the fitness device in the current gear, i is the gear of the fitness device, and i is a positive integer. 1-η i is the power generation coefficient of the generator.

[0127] In this case, the amount of fat consumed by the passenger when using the fitness device at a certain gear can be determined, so that the amount of fat burned by the passenger can be determined more accurately.

[0128] In the case where multiple passengers use the fitness device, the power generation coefficient of the generator is determined based on the friction coefficient of the transmission member of the fitness device in the current gear; the power generation of the generator is divided by the power generation coefficient to obtain the total energy of the multiple passengers during the fitness process, that is, the total energy of the multiple passengers during the fitness process is first determined by the following formula 4. Then the total energy is divided by the total number of stretching times to obtain the single energy; for any one of the multiple passengers, the single energy is multiplied by the number of stretching times of the corresponding stretching member used by the passenger to obtain the fat burning amount of the passenger during the fitness process.

[0129]

[0130] In this case, the total energy consumed by multiple passengers when using the fitness device at a certain gear can be determined more accurately, so that the fat burning amount of each passenger can be determined more accurately.

[0131] Optionally, when the passenger triggers the fitness device, the identity information of the passenger who triggers the fitness device can also be collected. The identity information can be face information, fingerprint information, etc., which is not limited in the embodiment of the present application. The specific collection process can include the following two possible ways.

[0132] The first possible way is that when the fitness device is triggered by voice or knocking, the microphone in the vehicle can locate the sound source, thereby determining the position of the passenger using the fitness device, and then the identity information of the passenger using the fitness device at that position can be collected through the camera based on the position information.

[0133] The second possible way is that when the fitness device is triggered by body sensing, gestures, etc., the camera in the vehicle can directly collect the identity information of the passenger who issued the triggering instruction after obtaining the triggering instruction of the passenger.

[0134] Furthermore, when the passenger is using the fitness device, the identity information of the target passenger who is currently using the fitness device can be obtained; when the identity information of the target passenger is different from the target identity information, the fat burning amount corresponding to the target identity information is saved and the fat burning amount of the target passenger is re-determined. When the identity information of the target passenger is the same as the target identity information, the fat burning amount corresponding to the target identity information is continued to be determined.

[0135] The target passenger is a passenger currently using the fitness device, and the identity information of the target passenger is used to uniquely identify the target passenger.

[0136] The target identity information is the identity information of the passenger who used the fitness device before the target passenger, that is, the identity information of the last passenger who used the fitness device during the current use of the fitness device.

[0137] In this case, if the identity information of the target passenger is different from the target identity information, it means that the passenger currently using the fitness device is different from the last passenger using the fitness device, that is, the user during the use of the fitness device has changed. Then, it is no longer possible to continue to determine the fat burning amount of the last passenger using the fitness device, but to determine the fat burning amount of the target passenger, the fat burning amount corresponding to the target identity information can be saved, and the fat burning amount of the target passenger can be re-determined. In other words, the fat burning amount of the last passenger using the fitness device can be saved first, and then the fat burning amount of the target passenger during the fitness process can be determined. Furthermore, if the last passenger using the fitness device uses the fitness device again, the fat burning amount of the passenger can be added to the fat burning amount corresponding to the target identity information previously saved to determine the total fat burning amount of the passenger during this fitness process.

[0138] If the identity information of the target passenger is the same as the target identity information, it means that the passenger currently using the fitness device is the same as the last passenger using the fitness device, that is, the user of the fitness device has not changed during this use. Then the fat burning amount of the passenger using the fitness device can be further determined, that is, the fat burning amount of the passenger corresponding to the target identity information can be further determined.

[0139] It is worth noting that after collecting the passenger's identity information, the passenger's identity information can also be identified.

[0140] Specifically, the operation of identifying the passenger's identity information may be: extracting features from the identity information to obtain identity information features corresponding to the identity information; and classifying the identity information features to obtain an identification result corresponding to the identity information.

[0141] In this case, the passenger identity corresponding to the identity information can be identified, so as to know which passenger is using the fitness device.

[0142] In the embodiment of the present application, if the identity information of the passenger cannot be identified, the identity of the passenger corresponding to the identity information can be automatically set. For example, if a passenger uses the fitness device for the first time and the vehicle camera collects the identity information of the passenger, but the identity of the passenger cannot be identified, the identity corresponding to the identity information of the passenger can be directly set as passenger A. In this way, the identity of each passenger using the fitness device can be known.

[0143] In this case, after obtaining the identity information of the target passenger currently using the fitness device, the identity information of the target passenger can be identified. If the identification result of the target passenger's identity information is different from the identification result of the target identity information, it is determined that the identity information of the target passenger is different from the target identity information. If the identification result of the target passenger's identity information is the same as the identification result of the target identity information, it is determined that the identity information of the target passenger is the same as the target identity information.

[0144] For example, Figure 4 This is a flow chart of another method for determining the amount of fat burned provided in an embodiment of the present application. Figure 4 , Figure 4 The process includes steps 401 to 405.

[0145] 401: Obtain the identity information of the target passenger currently using the fitness device.

[0146] 402: Determine whether the identity information of the target passenger is the same as the target identity information, that is, determine whether the user has changed during the use of the fitness device.

[0147] 403: When the identity information of the target passenger is different from the target identity information, the fat burning amount corresponding to the target identity information is saved.

[0148] For example, the target passenger's identity information is identified, and the identification result is passenger B. The target identity information is identified, and the identification result is passenger A. The identification result of the target passenger's identity information (passenger B) is different from the identification result of the target identity information (passenger A), so it is determined that the target passenger's identity information is different from the target identity information, and the fat burning amount of passenger A can be saved at this time.

[0149] 404: Determine the fat burning amount of the target passenger.

[0150] After the fat burning amount of passenger A is saved, the fat burning amount of passenger B can be determined, so that the fat burning amount of a passenger who newly uses the fitness device can be further determined.

[0151] Furthermore, after passenger A uses the fitness device again, the fat burning amount of passenger B can be saved, and the fat burning amount of passenger A can be determined. Moreover, the fat burning amount of passenger A can be accumulated based on the previously saved fat burning amount of passenger A to determine the total fat burning amount of passenger A during this use of the fitness device.

[0152] 405: When the identity information of the target passenger is the same as the target identity information, continue to determine the fat burning amount corresponding to the target identity information.

[0153] For example, the target passenger's identity information is identified, and the identification result is Passenger A. The target identity information is identified, and the identification result is Passenger A. The identification result of the target passenger's identity information (Passenger A) is the same as the identification result of the target identity information (Passenger A), so it is determined that the target passenger's identity information is the same as the target identity information, and the fat burning amount of Passenger A can be further determined.

[0154] Through the above 301-302, the fat burning amount of the passenger using the fitness device can be determined. Then, based on the fat burning amount of the passenger, the passenger can be reminded whether the passenger has overloaded the fitness this time.

[0155] Specifically, the passenger's target fat burning amount is obtained; the passenger's fat burning amount is subtracted from the target fat burning amount to obtain a target difference; and based on the target difference, corresponding reminder information is broadcast to the passenger.

[0156] The target fat burning amount is the amount of fat burning that the passenger needs to consume during the fitness process. Optionally, the target fat burning amount can be set by the passenger to be the amount of fat burning that the passenger hopes to consume during the fitness process. Optionally, the target fat burning amount can also be the historical average fat burning amount, which is the average fat burning amount of the passenger when using the fitness device in the past.

[0157] The reminder message is used to remind passengers to continue exercising or stop exercising. For example, the reminder message is "Your fat burning amount is insufficient this time, please continue exercising." For another example, the reminder message can be "You have reached the target for this exercise, please do not overwork yourself."

[0158] In this case, by subtracting the passenger's fat burning amount from the target fat burning amount, it can be determined whether the passenger's fat burning amount during this fitness process exceeds or meets the requirement. If it does not meet the requirement, the passenger should be reminded to continue exercising; if it exceeds the requirement, the passenger should be reminded to stop exercising to prevent the passenger from overloading the fitness.

[0159] Optionally, after the passenger stops using the fitness device for a second preset time, the above operation can be performed again, so as to remind the passenger to continue or stop the exercise when the passenger does not perform fitness exercise.

[0160] The second preset time length can be set in advance, and the second preset time length can be set by a technician according to actual needs. For example, the second preset time length is set to 1 minute.

[0161] Among them, based on the target difference, the operation of broadcasting the corresponding reminder information to the passengers can be: when the target difference is less than the first difference threshold, broadcasting the reminder information to continue exercising to the passengers; when the target difference is greater than or equal to the second difference threshold, broadcasting the reminder information to stop exercising to the passengers.

[0162] The first difference threshold and the second difference threshold can be set in advance, and the second difference threshold is greater than or equal to the first difference threshold. For example, the first difference threshold can be set to 0, and the second difference threshold can be set to 10.

[0163] In this case, if the target difference is less than the first difference threshold, it means that the passenger's current fat burning amount is less than the target fat burning amount, that is, the passenger's current fat burning amount has not reached the required fat burning amount, and the passenger needs to continue exercising. Then, a reminder message to continue exercising can be broadcasted to the passenger, so that the passenger can continue exercising to reach the required fat burning amount. If the target difference is greater than or equal to the second difference threshold, it means that the passenger's current fat burning amount is greater than the target fat burning amount, that is, the passenger's current fat burning amount has reached the required fat burning amount, and the passenger can stop exercising. Then, a reminder message to stop exercising can be broadcasted to the passenger to prevent the passenger from overloading the fitness.

[0164] It is worth noting that the fat burning amount determination method of the embodiment of the present application can conveniently determine the fat burning amount of the passenger during the fitness process. And by broadcasting the fat burning amount, the passenger can know his or her own fat burning situation in real time during the fitness process, so that he or she can reasonably arrange the fitness exercise time, maintain healthy and ideal fitness habits, and then get a healthy body. In addition, the fat burning amount determination method provided by the embodiment of the present application will not obtain too much exercise data, and will not cause the acquired exercise data to be inaccurate due to space limitations, thereby making the fat burning amount determination inaccurate, so that the final fat burning amount of the passenger during the fitness process is more real and reliable.

[0165] In an embodiment of the present application, the fitness device includes a generator, a transmission member and a stretching member. When the stretching member is stretched, the transmission member rotates, and when the transmission member rotates, the generator is driven to rotate, so that the generator generates electricity. Based on this, when a passenger uses the stretching member of the fitness device, mechanical energy is converted into electrical energy and friction loss energy. Therefore, when a passenger uses a fitness device in the car, the host of the vehicle can obtain the power generation of the generator in the fitness device, and then based on the power generation of the generator and the friction coefficient of the transmission member of the fitness device, the amount of fat burned by the passenger during the fitness process can be determined. In this way, the amount of fat burned by the passenger during the fitness process can be determined more conveniently, thereby improving the user experience.

[0175] Divide the total energy by the total number of stretches to get the single energy;

[0177] Optionally, the friction coefficient of the transmission member is associated with the gear position of the fitness device, and the determination module 502 is used to:
