[0051] Figure 1 A flow chart of a vehicle seat control method provided in an embodiment of the present application is shown in FIG. Figure 1 As shown, the method includes:

[0052] S10: Obtaining predicted road condition information and predicted driving time of the planned target driving route;

[0053] In a specific embodiment, the vehicle navigation system plans an optimal route based on the user's departure and destination locations, and uses this optimal route as the target route. Specifically, the system uses GPS or other positioning technologies to obtain the vehicle's current location and destination information to plan the optimal target route. Once the target route is determined, the system predicts road conditions along the target route and the estimated travel time for the vehicle along the target route, thereby generating predicted road condition information and a predicted driving time.

[0054] Furthermore, the predicted road condition information and predicted driving time of the planned target driving route are obtained through step S10.

[0055] It should be noted that the execution entity of the vehicle seat control method provided in the embodiments of this application can be a vehicle controller or a domain controller, and this application does not limit this. In addition, the vehicles provided in this application include but are not limited to sedans, sport utility vehicles (SUVs), multi-purpose vehicles (MPVs), off-road vehicles, pickup trucks, or other power-driven non-track-borne vehicles.

[0056] S11: Developing a seat massage plan for the vehicle while it is traveling on the target driving route based on the predicted road condition information and the predicted driving time;

[0057] Furthermore, in step S11, a massage plan for the seat when the vehicle is traveling on the target driving path is specified based on the predicted road condition information and the predicted driving duration of the target driving path. In some optional embodiments, specifying the massage plan includes specifying a start time and a massage duration for the seat massage.

[0058] It's understandable that the longer a driver drives and the more complex the road conditions, the higher their fatigue level. Consequently, they'll need seat massages more frequently and for longer periods of time. Therefore, when planning seat massages, it's important to first predict the road conditions and driving duration along the target route.

[0059] Furthermore, a massage plan is specified based on the predicted road conditions and predicted driving duration. Specifically, in one optional embodiment, when the predicted road conditions are more complex, such as when there are more congested sections, the driver's driving fatigue will increase. Therefore, seat massage can be activated under these special road conditions to relieve driver fatigue.

[0060] In another optional embodiment, as the driving time increases, the driver's driving fatigue becomes higher. Therefore, as the driving time continues to increase, the seat massage needs to be started more frequently and the massage time needs to be increased, so as to effectively relieve the driver's fatigue.

[0061] S12: When the vehicle is traveling on the target driving path, current road condition information is collected in real time;

[0062] S13: Control the seat to perform massage according to the current road condition information and the massage plan.

[0063] It is understandable that during the actual driving process of the vehicle, road conditions are ever-changing, which causes the actual driving time to vary accordingly. Therefore, in a specific embodiment, the seat massage needs to be adjusted according to the actual road conditions.

[0064] Specifically, when the vehicle is traveling on the target driving path, current road condition information is collected in real time through step S12, wherein the road condition information may include but is not limited to road congestion, road surface flatness, number of drivable lanes, and road streetlight conditions.

[0065] After obtaining the vehicle's current road condition information, the seat is automatically massaged in step S13 based on the current road condition information and the massage plan. In an optional embodiment, if the road section corresponding to the current road condition information is not a section where seat massage is required in the massage plan, but the current road condition information meets a preset condition, the seat is still massaged. The preset condition information may include road congestion and the current vehicle speed is less than a preset speed.

[0066] In another optional embodiment, if the road section corresponding to the current road condition information is a road section where seat massage is required in the massage plan, but the current road condition information indicates that seat massage under the current road conditions would affect driving safety, seat massage control for the current road section is canceled. If the current road condition information indicates that the current road conditions are safe for massage, seat massage is controlled based on the start time and massage duration planned in the massage plan.

[0067] In fact, it is understandable that different road conditions require different levels of driver concentration, and thus have different impacts on driving safety. Therefore, in an optional embodiment, whether to control seat massage can be determined based on the degree to which the road conditions affect the driver's concentration.

[0068] Specifically, if the road section corresponding to the current road condition information is a road section where the massage plan requires seat massage to be activated, in an optional embodiment, the degree of concentration of the driver's driving attention on the current road section is determined based on the road condition information. When the concentration is less than a threshold, the seat is controlled to perform massage based on the activation time and massage duration planned in the massage plan. If the concentration is not less than the threshold, the seat massage for the current road section in the massage plan is canceled.

[0069] Therefore, the vehicle seat control method provided in the embodiment of the present application plans the massage time of the vehicle seat according to the road condition information and driving time of the vehicle's target driving path, and during the actual driving process, automatically adjusts and controls the seat according to the actual driving road conditions and the pre-planned massage planning scheme, thereby relieving driver fatigue in a timely manner and improving vehicle driving comfort and driver experience.

[0070] Figure 2 This is a flow chart of a method for controlling a vehicle seat provided in another embodiment of the present application. In an optional embodiment, as Figure 2 As shown, based on the predicted road condition information and the predicted driving time, a seat massage planning scheme is formulated when the vehicle is driving on the target driving path, including:

[0071] S20: Determine whether the predicted road condition information meets the high-quality road condition condition. If so, proceed to step S21; if not, proceed to step S22;

[0072] In a specific embodiment, when formulating a massage planning scheme based on the predicted road condition information and the predicted driving time, step S20 is first used to determine whether the predicted road condition information meets the high-quality road condition condition.

[0073] It is understandable that when road conditions are excellent, the driver's focus is relatively low, and the driving environment is relatively safe. In this case, the seat massage can be activated to relieve driver fatigue. However, when road conditions are complex and changeable, the driver's focus is relatively high, and safe driving is the primary consideration. Therefore, activating the seat massage and causing driver distraction is not appropriate. Therefore, in one optional embodiment, when formulating the massage plan, it is necessary to first determine whether the predicted road conditions are excellent.

[0074] Among them, high-quality road conditions may include but are not limited to a flat road surface, an unobstructed road (i.e., no congestion), a spacious road, good road lighting, no mountainous road sections, and a large number of straight road sections. Correspondingly, high-quality road conditions may include but are not limited to a road surface flatness greater than a flatness threshold, a road smoothness greater than a smoothness threshold, a road width greater than a width threshold, road lighting brightness reaching a brightness threshold, a straight-line driving length greater than a length threshold, and a number of target straight road sections with straight-line driving lengths greater than the length threshold greater than a number threshold.

[0075] In an optional embodiment, whether the predicted road condition information meets the high-quality road condition conditions can be determined by at least one of the following methods: collecting point cloud data through a vehicle lidar and analyzing the point cloud data to determine whether the high-quality road condition conditions are met; collecting infrared data through a vehicle infrared scanner and analyzing the infrared data to determine whether the high-quality road condition conditions are met; collecting video images through a camera and analyzing the collected video images to determine whether the high-quality road condition conditions are met.

[0076] S21: Formulate a massage plan based on the predicted driving time;

[0077] S22: extracting a designated road section from the target driving path; and using the designated road section as the road section for controlling seat massage; the designated road section includes at least one of a road section with a congestion duration greater than a preset duration, a road section with a flat road surface, and a road section with a straight driving mileage greater than a preset mileage.

[0078] When the predicted road condition information meets the high-quality road condition conditions, it indicates that the target driving path has good road conditions and a high driving safety factor. At this time, a massage planning scheme can be formulated through step S21, that is, a massage planning scheme is formulated according to the predicted driving time.

[0079] When the predicted road condition information does not meet the high-quality road condition criteria, indicating that the target driving route has poor road conditions, a massage plan needs to be specified based on the predicted road condition information. Specifically, when the road condition is poor, sections of the entire target driving route where seat massage is possible are identified. Specifically, designated sections are extracted from the target driving route and used as the sections for controlling seat massage.

[0080] The designated road section includes at least one of a road section with a congestion duration greater than a preset duration, a road section with a flat road surface, and a road section with a straight-line driving distance greater than a preset distance. The flat road section is a road section with a road surface flatness greater than a flatness threshold.

[0081] In fact, the designated road section is a road section that requires relatively low driver concentration. Therefore, in an optional embodiment, the road section's concentration requirement for the driver can also be determined based on the predicted road condition information, and the road section with a concentration less than a threshold can be used as the designated road section, that is, the road section with a concentration less than a threshold can be used as the road section for controlling seat massage.

[0082] Based on the above embodiments, Figure 2 As shown, a massage planning scheme is formulated based on the predicted driving time, including:

[0083] S210: Segmenting the predicted driving time to obtain a plurality of massage start times for the seat; wherein the time between adjacent massage start times decreases in chronological order;

[0084] In a specific embodiment, when the predicted road condition information indicates that the road conditions for the currently planned target driving route are good, a massage planning scheme can be formulated based on the predicted driving time. Specifically, it is understood that although the road conditions are good, as the driving time continues to increase, the driver's fatigue increases, and the need for seat massage also increases.

[0085] Therefore, in an optional embodiment, the predicted driving time is segmented in step S210 to obtain multiple seat massage activation times. The segmentation is performed in chronological order (i.e., in chronological order of occurrence), with the duration between adjacent massage activation times decreasing. In other words, as driving time increases, the frequency of seat massage increases, thereby relieving driver fatigue through timely seat massage.

[0086] In an optional embodiment, if the predicted driving time is P and the remaining driving time is O, where O≤P, the start of the seat massage is divided into n stages, that is, n massage start times are set, n is a natural number greater than 0, and the massage start time is A(n), then A(n) satisfies the calculation formula: A(n)=A(n-1)+[A(n-1)-n / 10]. Among them, A(1) is the initial value, that is, the initial value of the first seat massage, the initial value is a preset value, and the preset value can be set according to the experience value, or according to the user's historical massage preferences, which is not limited in this application. In addition, it is worth noting that the number n of massage start times is related to the predicted driving time P and the initial value A(1). For ease of understanding, an example will be given below.

[0087] For example, if the predicted driving time P = 20 hours and A(1) = 4 hours, the first stage of seat massage is started, that is, the first massage starts after the vehicle has been driving for 4 hours, that is, A(1) = 4 hours. The second stage is: A(2) = A(1) + [A(1) - 2 / 10] = 7.8 hours, that is, the second massage starts after the vehicle has been driving for 7.8 hours. The third stage is: A(3) = A(2) + [A(2) - 3 / 10] = 11.3 hours, that is, the second massage starts after the vehicle has been driving for 11.3 hours. The fourth stage is: A(4) = A(3) + [A(3) - 4 / 10] = 14.4 hours, that is, the fourth massage starts after the vehicle has been driving for 14.4 hours. The fifth stage is: A(5) = A(4) + [A(4) - 5 / 10] = 17 hours, that is, the fifth massage starts after the vehicle has been driving for 17 hours. The sixth stage is: A(6)=A(5)+[A(5)-6 / 10]=19 hours, that is, the sixth massage start time is after the vehicle has been running for 17 hours.

[0088] Therefore, when the predicted driving time P is 20 hours, the massage start times are 4 hours, 7.8 hours, 11.3 hours, 14.4 hours, 17 hours, and 19 hours after the vehicle has driven. The time intervals between adjacent massage start times are 3.8 hours, 3.5 hours, 3.1 hours, 2.6 hours, and 2 hours, respectively. In other words, the time intervals between adjacent massage start times decrease, which means that the frequency of massage to relieve driver fatigue is increasing.

[0089] S211: Setting different massage durations corresponding to each massage start moment; wherein, each massage duration increases in chronological order, and the massage duration is shorter than the duration between adjacent massage start moments.

[0090] Furthermore, after the predicted driving time is segmented to determine multiple massage start times in step S210, different massage durations are set corresponding to different massage start times in step S211. It is understood that as driving time increases, the driver's fatigue level increases, and the massage duration requirement increases. Therefore, in a specific embodiment, when setting the massage durations for different stages, each massage duration increases in chronological order, and the massage duration is shorter than the duration between adjacent massage start times.

[0091] That is to say, as the driver's driving time increases, the longer the seat massage is started each time. For example, the first massage is 10 minutes, the second is 12 minutes, and the third is 15 minutes. The massage time is continuously increased until the end of the trip.

[0092] It should be noted that the massage duration is less than the duration between adjacent massage start times. For example, the first massage is 4 hours later and the second massage is 5.8 hours later. The duration between adjacent massage start times is 5.8-4=1.8 hours. The first massage is 4 hours later and the massage duration is less than 1.8 hours.

[0093] Furthermore, it should be noted that when setting the massage duration, the massage duration may be increased once for each increment of the massage start time, and the incremented duration may be the same. Alternatively, the massage duration may be increased once for each increment of the massage start time, and the incremented duration may be different. Alternatively, the massage duration may be increased once for each increment of two massage start time times, and the incremented duration may be the same. This application does not specifically limit the method for increasing the massage duration.

[0094] In an optional embodiment, controlling the seat to perform massage according to current road condition information and a massage plan includes:

[0095] Determining whether the current driving section is a section corresponding to the massage planning scheme for controlling the seat to perform massage;

[0096] If yes, the seat is controlled to perform massage based on the massage planning scheme;

[0097] If not, when the current road condition information meets the preset conditions, the seat is controlled to perform massage and a new massage plan is formulated; wherein the preset conditions include at least one of the first condition and the second condition; the first condition includes that the road surface is flat and the number of other traffic participants except vehicles is less than the preset number; the second condition includes that the current driving section is a congested section and the vehicle speed is less than the preset speed.

[0098] In an optional embodiment, when controlling the seat for massage based on the current road condition information and the massage planning scheme, first, it is necessary to determine whether the road section on which the vehicle is currently traveling is the corresponding road section in the pre-established massage planning scheme, that is, to determine whether the current driving road section is the road section to be massaged in the massage planning scheme.

[0099] Among them, the current driving section refers to the section corresponding to the current road condition information conditions that the vehicle can collect during driving. For example, the laser radar can scan the section within the obstacle range, or the vehicle camera can collect the section within the video image range in the direction of travel.

[0100] It is understood that if the current driving section corresponds to the section for which the seat is to be massaged in the massage plan, that is, if there is a section to be massaged in the massage plan on the current driving section, the seat will be massaged based on the massage plan. In other words, if the current driving section has a pre-set massage start time, the massage will be performed according to the pre-set plan.

[0101] In an optional embodiment, if the current driving section is not the section corresponding to the massage plan for controlling the seat for massage, it is necessary to determine whether massage can be initiated based on the road conditions of the current driving section. Specifically, it is determined whether the current road condition information meets at least one of a first condition and a second condition. If so, the current road condition indicates a high safety factor and the seat massage can be initiated. If not, the current road condition indicates a low safety factor and requires the driver to concentrate on driving, so seat massage should not be initiated.

[0102] Among them, the first condition includes that the road surface is flat and the number of traffic participants other than vehicles is less than a preset number. It should be noted that, in an optional embodiment, the flatness of the road surface can be determined by analyzing data collected by an infrared scanner or a lidar, and the number of other traffic participants can be determined by video images collected by the vehicle camera.

[0103] The second condition is that the current road section is congested and the vehicle's speed is less than a preset speed. It's understood that when a vehicle is traveling on a congested road section at a low speed, the driving environment is relatively safe and driver fatigue is high in congested sections. In this case, to alleviate driver fatigue and boredom in congested sections, seat massage can be activated.

[0104] In an optional embodiment, the current driving section is not the section corresponding to the massage planning scheme for controlling the seat for massage, and after determining that massage can be started based on the road conditions of the current driving section, a new massage planning scheme is formulated based on the end time of the massage.

[0105] Based on the above embodiment, as an optional embodiment, a new massage planning scheme is formulated, including:

[0106] Determine the remaining road condition information and remaining driving time corresponding to the remaining untraveled routes;

[0107] Determine whether the remaining road condition information meets the high-quality road condition conditions;

[0108] If satisfied, the remaining driving time is divided to formulate a new massage plan;

[0109] If not, the target road segment is extracted from the remaining untraveled paths to formulate a new massage planning scheme.

[0110] In a specific embodiment, when formulating a new massage plan, the remaining road condition information and remaining driving time corresponding to the vehicle's remaining untraveled route, starting from the current massage end time, are first determined based on navigation information. A determination is then made as to whether the remaining road condition information meets the criteria for high-quality road conditions. Similarly, high-quality road conditions may include, but are not limited to, a flat road surface, an unobstructed road (i.e., no congestion), a wide road, good road lighting, no hilly sections, and a high number of straight sections.

[0111] It's understandable that when the remaining road condition information meets the high-quality road condition requirement, the road condition indicates that the driver's focus is relatively low, resulting in a safer driving environment. Therefore, the remaining driving time can be segmented to obtain multiple massage start times for the seat. Different massage durations can be set starting from each massage start time, thereby developing a new massage plan.

[0112] It should be noted that the principles of dividing the remaining driving time and formulating the massage time in this application are the same as those of the above-mentioned embodiment, that is, in chronological order, the time between adjacent massage start moments decreases, while the time of each massage increases, and the massage time is less than the time between adjacent massage start moments.

[0113] It is worth noting that before determining whether the remaining road condition information meets the high-quality road condition conditions, the vehicle seat control method also includes: determining whether the remaining driving time is greater than the time threshold; if so, entering the step of determining whether the remaining road condition information meets the high-quality road condition conditions, and executing subsequent steps; otherwise, ending.

[0114] It is understandable that if the remaining driving time of the vehicle is too short, that is, the remaining mileage is too short, in order to avoid wasting resources, the massage planning scheme may not be re-formulated and updated.

[0115] In an optional embodiment, when the remaining road condition information does not meet the high-quality road condition conditions, the road condition of the remaining untraveled path is poor, and it is necessary to extract the target section, and use the extracted target section as the section for controlling the seat massage, thereby formulating a new massage planning scheme.

[0116] The target road section includes at least one of a road section with a congestion duration greater than a preset duration, a road section with a flat road surface, and a road section with a straight-line driving distance greater than a preset distance. It is worth noting that the flat road section is a road section with a road surface flatness greater than a flatness threshold.

[0117] It should be noted that when determining the target road section, the degree to which the driver's driving experience is concentrated on the road section can also be determined, and the road section with a concentration less than a threshold can be used as the target road section. That is, the road section with a concentration less than the threshold can be used as the road section for controlling seat massage. This application does not limit the method for extracting the target road section.

[0118] Figure 3 A flow chart of a vehicle seat control method provided in another embodiment of the present application is shown as follows: Figure 3 As shown, in an optional embodiment, controlling the seat to perform massage includes:

[0119] S30: Obtaining massage mode influencing parameters including at least one of a historical massage mode recommendation strategy, a driver fatigue state, and a historical massage preference parameter; wherein the historical massage mode recommendation strategy includes at least one of a correspondence between different driving sections and massage parameters, and a correspondence between different driving road conditions and massage parameters;

[0120] In a specific embodiment, when formulating a massage planning plan for the seat, the current road condition information during real-time driving of the vehicle, as well as the predicted road condition information and predicted driving time of the planned target driving path are taken into consideration. When starting the seat for massage, it is necessary to determine the target massage mode of the current massage, that is, to determine the intensity and technique of the current massage.

[0121] The determination of the target massage mode is related to massage mode influencing parameters, wherein the massage mode influencing parameters include at least one of historical massage mode recommendation strategies, driver fatigue status, and historical massage preference parameters.

[0122] It will be appreciated that if the target driving route is a historically driven route, a historical massage mode recommendation strategy will be stored in the database. This strategy includes at least one of the following: a correspondence between different driving sections and massage parameters, and a correspondence between different driving conditions and massage parameters. Massage parameters include massage area, massage intensity, massage techniques, and seat parameters. Seat parameters include backrest angle, seat height, and horizontal distance from the steering wheel. The target massage mode for the current seat to be massaged can be determined based on the historical massage mode recommendation strategy.

[0123] Furthermore, the driver's current fatigue state is closely related to the target massage mode. Therefore, the driver's fatigue state needs to be considered when determining the target massage mode. Of course, while the vehicle is in motion, the driver can set their preferred massage mode through various methods, such as voice settings and manual adjustment. Therefore, the target massage mode can also be determined based on historical massage preference parameters.

[0124] S31: Determine a target massage mode according to massage mode influencing parameters;

[0125] S32: Control the seat to enter the target massage mode.

[0126] After obtaining the massage mode influencing parameters through step S30, the target massage mode is determined based on the massage mode influencing parameters. In an optional embodiment, when determining the target massage mode, different weight coefficients can be set for different massage mode influencing parameters, and the parameters, intensity and technique of the chair can be determined based on the different weight coefficients.

[0127] Furthermore, the seat is controlled to enter a target massage mode, that is, the seat is started to perform massage according to the massage part, massage intensity, massage technique and seat parameter settings corresponding to the target massage mode.

[0128] It should be noted that massage modes can be classified according to different massage parts, massage intensity, or massage techniques. This application does not limit the classification method of massage modes.

[0129] Therefore, when it is determined that the road section is safe and suitable for seat massage based on the current road condition information and massage planning scheme, seat massage is performed based on at least one of the historical massage mode recommendation strategy, driver fatigue status and historical massage preference parameters. While ensuring safe driving, the driver is provided with the optimal massage plan, thereby effectively relieving driving fatigue and improving the driving experience.

[0130] In an optional embodiment, the vehicle seat control method provided in the embodiment of the present application further includes:

[0131] Storing the corresponding driving information and actual massage parameters of the seat when the vehicle is traveling on the target driving path;

[0132] Based on driving information and actual massage parameters, the historical massage mode recommendation strategy is optimized.

[0133] During vehicle driving, the corresponding driving information and actual massage parameters of the seat when driving on the target driving path are stored in real time, and the collected driving information and actual massage parameters are used to optimize the historical massage mode recommendation strategy through machine learning algorithms.

[0134] Understandably, while the vehicle is in motion, seat massage is adjusted in real time based on actual road conditions, driver fatigue, and the driver's seat massage preferences. Furthermore, as the vehicle continues to drive, the historical massage mode recommendation strategy is continuously optimized based on driving information and actual massage parameters. This allows for reliable massage mode recommendations to be provided to the vehicle, ensuring the most comfortable massage for the driver under varying road conditions.

[0135] In an optional embodiment, the vehicle seat control method provided in the embodiment of the present application further includes:

[0136] When driver fatigue information is collected and the driver fatigue information indicates that the driver is in at least one of severe fatigue and sleep state, the seat is controlled to enter a prompt massage mode corresponding to fatigue driving;

[0137] When the ambient temperature is collected and is lower than the preset temperature, the seat heating is controlled;

[0138] When the driver's body shape information is collected, before the vehicle is powered on and starts driving, the seat parameters are adjusted according to the driver's body shape information; among them, the seat parameters include the backrest angle, seat height and the horizontal distance between the seat and the steering wheel.

[0139] In a specific embodiment, the vehicle collects driver fatigue information in real time, and determines whether the driver is currently in at least one of severe fatigue and sleep state based on the collected fatigue information. If so, the seat is controlled to enter a prompt massage mode corresponding to fatigue driving, so as to remind the user to pull over and rest in time, thereby improving driving safety.

[0140] The massage mode prompt may include controlling the vibration of the seat and simultaneously sending a signal to the vehicle system to output a corresponding prompt. The driver fatigue information may be collected by using a vehicle camera to capture and analyze a video image of the driver.

[0141] In an optional embodiment, the vehicle can also collect the ambient temperature in real time, where the ambient temperature includes the vehicle's indoor temperature and the vehicle's outdoor temperature. When the ambient temperature is lower than the preset temperature, the seat is controlled to be heated to provide the driver with a comfortable driving environment.

[0142] In another optional embodiment, when the vehicle is powered on, the driver's body information can be collected, where the body information includes weight, gender, height, etc. Pressure sensors can be set under the seat and on the backrest to determine the driver's weight and height based on the pressure data collected by the pressure sensors. Furthermore, the driver's height and gender can be further determined based on the images collected by the vehicle camera.

[0143] Furthermore, after determining the driver's body shape information, before the vehicle is powered on and starts driving, the seat back angle, seat height and horizontal distance between the seat and the steering wheel are adjusted according to the driver's body shape information, thereby ensuring that the seat adapts to the driver's body shape and provides the most comfortable initial posture.
