Description

Technical Field

[0001] This application relates to the field of vehicles, and in particular to vehicle seat adjustment methods, vehicle seat adjustment devices, and vehicles. Background Technology

[0002] In vehicle structures, vehicle seats are often rigidly connected to the entire vehicle. When the vehicle turns, the centripetal force is usually provided by the friction between the occupant and the seat cushion, supporting the occupant in a circular motion. Therefore, currently, the occupant's riding experience is relatively poor when the vehicle is turning.

[0003] To enhance passenger comfort, related technologies often focus on improving seat structure. By creating a height difference between the left and right sides of the seat, an additional lateral force is provided to the occupant. This force, in turn, provides the centripetal force needed for the body's circular motion during cornering, thus improving comfort. However, in actual driving, adjusting seat height often involves sensor measurements, data calculations, and information processing, resulting in a lag in the adjustment action. Furthermore, the triggering mechanism for seat adjustments is strongly correlated with the steering wheel's turning angle, leading to frequent seat adjustments when changing lanes on straight roads, negatively impacting passenger comfort.

[0004] There is currently no effective solution to the problems of seat adjustment delay and frequent false triggering in related technologies. Summary of the Invention

[0062] This embodiment provides a method for adjusting a vehicle seat. Figure 2 This is a flowchart of the vehicle seat adjustment method in this embodiment, as shown below. Figure 2 As shown, the process includes the following steps:

[0063] Step S210: Based on the road information, determine the curvature information of the vehicle when it turns within a preset time period in the future.

[0064] Road information may specifically include the extension of the road on both sides, the driving direction markings corresponding to the lanes, and the driving direction indicated by roadside signs. This road information can be obtained based on the vehicle's perception system or navigation information. After obtaining the road information, if it is determined whether the vehicle will turn within a preset time period, the curvature information of the vehicle when turning is calculated in advance, such as the turning angle, turning arc, or turning radius. Therefore, based on this step, it is possible to predict in advance whether the vehicle needs to turn based on road condition detection, and to calculate the curvature information in advance. The preset time period can be set by those skilled in the art based on the timeliness requirements of the road turning prediction in the actual application scenario, the adjustment speed of the vehicle seat adjustment mechanism, and the speed of data processing and analysis by the vehicle control system, etc. This embodiment does not specifically limit this.

[0065] Step S220: Determine the reference height difference of the vehicle seats of the driving vehicle based on the curvature information; wherein, the reference height difference is the height difference between the left and right sides of the same vehicle seat.

[0066] The aforementioned reference height difference must meet the following condition: when the vehicle seat is positioned at this reference height difference, it can provide a preset lateral force to the occupant when the vehicle turns using the curvature information obtained in step S210. A mathematical relationship between the reference height difference and curvature information can be pre-established based on the force analysis of the occupant during turning. This ensures that when the vehicle turns with the corresponding curvature information, the lateral force provided by the vehicle seat based on this height difference can support the occupant's circular motion during turning, thereby improving occupant comfort during turning. Figure 3a This is a top-view diagram of a vehicle's turning trajectory. Figure 3b This diagram illustrates the force analysis of occupants under different vehicle seats. (Combined with...) Figure 3a and Figure 3b When the vehicle turns, it will follow Figure 3a The solid arrow in the diagram indicates the radius of the circular motion. When the vehicle is turning, in the original seating configuration where there is no height difference between the two sides of the seat, with the positive direction from left to right of the vehicle body, the force supporting the occupant in a synchronized circular motion comes from the frictional force f between the occupant and the seat cushion. 摩擦 At this time, the support force F provided by the vehicle seat 支撑 It cannot provide support for the occupant to perform circular movements. The adjustable vehicle seat with height difference on both sides used in this embodiment provides a support force F. 支撑 The supporting force F 支撑分力 It provides support for the occupant during circular movements, thus improving riding comfort. Among these, Figure 3b In this context, m represents the mass of the passenger and g represents the acceleration due to gravity.

[0067] Step S230: Control the current height difference of the vehicle seat to keep the absolute value of the difference between the current height difference and the reference height difference within a preset range.

[0068] After calculating the aforementioned height difference, the seat adjustment mechanism can be controlled to adjust the height difference between the two sides of the vehicle seat. Specifically, first, the actual current height difference of the vehicle seat is measured. If the absolute value of the difference between the current height difference and the reference height difference is within a preset range, then there is no need to adjust the height difference of the vehicle seat; otherwise, the current height difference needs to be adjusted so that the absolute value of the difference between the current height difference and the reference height difference is within the preset range.

[0069] Understandably, the reference height difference calculated in step S220 above is a theoretical height difference calculated in advance based on the predicted curvature information before the vehicle reaches the turning section, so that the seat adjustment mechanism can adjust the seat height in advance based on this reference height difference. However, when the vehicle actually reaches the turning section, the corresponding target height difference can be further determined based on the actual curvature information, vehicle speed, and user-set seat adjustment intensity, and the vehicle seat can be adjusted based on the target height difference and the actual current height difference.

[0070] In related technologies, improvements to the seat structure are often made by creating a height difference between the left and right sides of the seat to provide an additional lateral force for the occupant. This force is then used to provide the centripetal force for the body's circular motion when the vehicle is turning, thereby improving ride comfort. However, in actual driving, adjusting the seat height difference often involves sensor measurement, data calculation, and information processing, resulting in a lag in the adjustment action. Furthermore, the triggering method for seat adjustment is strongly correlated with the steering wheel's turning angle, so when the vehicle is changing lanes on a straight road, seat adjustments are frequently triggered, affecting the occupant experience.

[0071] To address this, this embodiment, based on the aforementioned steps and while utilizing the seat adjustment mechanism to adjust the height difference between the two sides of the seat, incorporates vehicle intelligence to proactively identify the driver's driving intentions (whether to turn) based on road information. This allows for predictive adjustment of the seat position, enabling faster adjustment of the seat height difference during turns and resolving the lag in seat adjustments present in related technologies. Furthermore, this embodiment's turn prediction based on road information avoids the problem of accidental seat adjustments during straight-line lane changes, a problem present in related technologies. Therefore, this embodiment enhances the user's riding experience.

[0072] In some embodiments, the seat adjustment mechanism itself features a compact structure and precise control, which is beneficial for vehicle integration and comfort calibration. A height difference adjustment function activation switch can also be set for the vehicle seat, along with multiple adjustable active seat movement ranges to improve the user's riding experience. Additionally, a balance position locking mechanism can be provided, which allows the vehicle seat to still be used as a regular seat without height difference in the event of motor failure, thereby improving seat safety.

[0073] As one of the most frequently interacted components, vehicle seats are the most strongly perceived by occupants. This embodiment can provide intelligent turning prediction logic to help improve seat comfort, and has great application prospects in both private cars and commercial buses.

[0074] Through steps S210 to S230, based on road information, the curvature information of the vehicle when it turns within a preset time period is determined; based on the curvature information, the reference height difference of the vehicle's seats is determined; wherein, the reference height difference is the height difference between the left and right sides of the same vehicle seat; the absolute value of the difference between the current height difference of the vehicle seats and the reference height difference is controlled to remain within a preset range. This system predicts vehicle turns based on road information, and when a turn is predicted, it performs seat adjustments in advance based on the curvature information of the turn, thereby reducing the delay in seat height difference adjustment and avoiding accidental triggering of seat adjustments during straight-line lane changes.

[0075] In one embodiment, before determining the curvature information of the vehicle when it turns within a preset time period based on road information, the vehicle seat adjustment method may further include:

[0076] Determine whether navigation information for the vehicle is available; if so, predict whether the vehicle will turn in the future based on the navigation information; the navigation information includes road information for the vehicle.

[0077] Figure 4 This is a schematic diagram of navigation information in this embodiment. Figure 4 As shown, the starting point of the dashed arrow is the vehicle's current location, and the ending point can be the user's pre-set navigation destination. Therefore, the vehicle's navigation information includes information about the road the vehicle is currently traveling on and will subsequently traverse (straight roads, left or right turns, and corresponding curve information). By reading the vehicle's navigation information, the turning sections the vehicle will pass through can be predicted in advance, enabling predictive navigation. This navigation information can be obtained from the vehicle's in-vehicle navigation system or, based on communication with the user's mobile device, from the navigation application on the user's mobile device. The specific method of reading the navigation information is not limited.

[0078] This embodiment, by acquiring navigation information, can control the height adjustment mechanism to adjust the height in advance based on the road information that the vehicle will pass through in the navigation information, thereby accurately reducing centrifugal force and avoiding delays in seat adjustment.

[0079] Specifically, in one embodiment, if navigation information is not read, the above vehicle seat adjustment method may further include:

[0080] Based on the turn signal signals of the vehicle and the image information collected by the vehicle's forward-facing camera, road information is obtained, and based on the road information, it is predicted whether the vehicle will turn in the future.

[0081] For example, when the user is not using in-car navigation or there is no navigation signal, the system can determine whether the vehicle has a turning tendency based on the vehicle's turn signal signals. Furthermore, by analyzing the road lines on both sides of the road in the vehicle's direction of travel as identified by the vehicle's forward-facing camera, the curvature of the turning section can be determined to predict whether the vehicle will turn in the future. Additionally, it can identify roadside signs to predict whether the vehicle will turn in advance. Figure 5 This is a schematic diagram of the image captured by the vehicle's forward-facing camera in this embodiment. Figure 5 As shown, the vehicle's forward-facing camera can capture information such as road extension lines and roadside signs.

[0082] In this way, the vehicle's perception system can identify and determine whether the vehicle is turning based on information from multiple dimensions, thereby improving the accuracy of turning prediction and avoiding misjudgments.

[0083] In another embodiment, determining the reference height difference of the vehicle seats based on curvature information may specifically include:

[0084] Based on the predicted curvature information, and combined with the pre-established mathematical relationship between the curvature information and the height difference between the left and right sides of the vehicle seat, the reference height difference is determined. The mathematical relationship is constructed based on the relationship between the centripetal force of the passenger and the curvature information when the vehicle is turning, and the relationship between the lateral force provided by the vehicle seat and the height difference between the two sides of the vehicle seat.

[0085] Figure 6 This is a schematic diagram illustrating the force analysis on the occupants during a vehicle turn. (Example:) Figure 6 As shown, assume the vehicle's positive turning direction is from left to right. During the turning process, the centripetal force of the passengers is F. 向心 =mv 2 / R. When a height difference occurs between the two sides of the seat, the supporting component of the force provides the centripetal force to the occupant, i.e., F. 支撑分力 =F 向心 According to the decomposition of forces, the supporting component F 支撑分力 It can be represented in the following form:

[0086]

[0087] Therefore, the mathematical relationship between the reference height difference ΔH and the curvature information (turning radius R) can be constructed as follows:

[0088]

[0089] Where m is the mass (weight) of the passenger, in kilograms (kg); v is the speed of the vehicle, which can be measured by a vehicle speed sensor; R is the radius of the vehicle's circular motion, which can be determined by identifying the turning radius based on navigation information, or by identifying the turning radius based on lane lines from a camera, or by measuring the steering wheel angle from a steering wheel angle sensor in the vehicle's infotainment system and then looking up a table to find the correspondence between the steering wheel angle and the vehicle's circular motion. L is the left-right distance of the support structure that drives the vehicle seat movement; g is the constant of gravitational acceleration, which can be 9.8; in addition, when the vehicle turns from left to right, this ΔH value can be positive, and when turning from right to left, this ΔH value can be negative; after calculating ΔH, the control system adjusts the height difference (H1-H2) of the vehicle seat in real time by controlling the seat adjustment mechanism to ensure that the current height difference (H1-H2) is consistent with the ΔH value. H1 represents the height measurement value from the left side height sensor of the seat's motion support; H2 represents the height measurement value from the right side height sensor of the seat's motion support.

[0090] This embodiment can accurately construct the mathematical relationship between curvature information and reference height difference, thereby enabling the vehicle seat, after being adjusted according to the reference height difference, to provide the occupant with the required lateral force, so that the centripetal force on the occupant is not provided by friction, thus improving riding comfort.

[0091] Additionally, in one embodiment, controlling the absolute value of the difference between the current height difference of the vehicle seat and the reference height difference to remain within a preset difference range may specifically include:

[0092] The system acquires the measured values ​​from the height sensors on the left and right sides of the vehicle seat in real time; determines the current height difference of the vehicle seat based on the measured values; checks whether the absolute value of the difference between the current height difference and the reference height difference is within the range of difference; if not, it controls the seat adjustment mechanism to adjust the current height difference until the absolute value of the difference between the adjusted current height difference and the reference height difference is within the range of difference.

[0093] Figure 7 This is a structural schematic diagram of a seat adjustment mechanism according to this embodiment. Figure 7As shown, the seat adjustment mechanism may include a fixed support 701, a bearing mounting base 702, a bearing 703, a transmission support shaft 704, a motion support 705 (i.e., the support structure that drives the vehicle seat to move as described above), a transmission gear 706, a drive motor 707 (i.e., the seat adjustment motor mentioned above), a limit pin 708, and height sensors 709 and 710. The fixed support 701 connects to the vehicle body and provides support for the seat, while also providing a fixed mounting point for the drive motor 707. The bearing mounting base 702 is an integral structure with the fixed support 701, providing a mounting surface for the bearing 703. The bearing 703 is installed within the bearing mounting base 702. The transmission support shaft 704 connects the transmission gear 706 to the motion support 705. The motion support 705 connects to the vehicle seat, driving its movement. The transmission gear 706 transmits the rotational torque of the drive motor 707 to the motion support 705 via the transmission support shaft 704, causing the motion support 705 to rotate and changing the height difference between the left and right sides of the vehicle seat. The drive motor 707 receives signals from the control system and executes corresponding rotation operations, providing power for the rotation of the motion support 705. In the event of a failure of the drive motor 707, the limit pin 708 locks the bearing mounting seat 702 and the motion support 705 in a horizontal position, preventing the motion support 705 from moving and ensuring the safety of the vehicle seat in extreme environments. Height sensors 709 and 710 measure the height difference between the two sides of the vehicle seat and feed it back to the control system.

[0094] Therefore, the control system can monitor the current height difference between the left and right sides of the vehicle seat in real time through the height sensor, and determine whether the absolute value of the difference between it and the reference height difference is within the preset difference range (e.g., less than 0.3 cm). If so, the height difference will not be adjusted; otherwise, the current height difference will continue to be adjusted until the absolute value of the difference is within the range, thereby providing a better support experience for the passenger.

[0095] If the absolute value of the difference between the current height difference and the reference height difference exceeds the aforementioned range, it is necessary to determine whether the current height difference is excessive or insufficient. Taking the case where the height difference between the two sides of the vehicle seat is too large as an example, the drive motor 707 needs to rotate the transmission support shaft 704 in the forward direction, driving the moving support seat 705 to rotate. During the rotation, the relationship between the current height difference and the actual height difference is continuously judged. When the absolute value of the difference is within the aforementioned range, the drive motor 707 stops rotating and hovers at the current position. Therefore, this embodiment can achieve accurate adjustment of the vehicle seat height difference.

[0096] In one embodiment, controlling the seat adjustment mechanism to adjust the current height difference until the absolute value of the difference between the adjusted current height difference and the reference height difference is within a certain range may include:

[0097] The seat adjustment motor is controlled to rotate, adjusting the current height difference until the absolute value of the difference between the current height difference and the reference height difference falls within the acceptable range. Adjusting the height difference via motor rotation ensures accurate and stable height adjustment.

[0098] In one embodiment, controlling the seat adjustment motor to rotate to adjust the current height difference until the absolute value of the difference between the current height difference and the reference height difference is within a certain range may include:

[0099] When the current height difference is higher than the reference height difference, the seat adjustment motor is controlled to rotate forward to adjust the current height difference until the absolute value of the difference between the current height difference and the reference height difference is within the difference range; when the current height difference is lower than the reference height difference, the seat adjustment motor is controlled to rotate in reverse to adjust the current height difference until the absolute value of the difference between the current height difference and the reference height difference is within the difference range.

[0100] By rotating the motor in either the forward or reverse direction, the different height differences between the left and right sides of the vehicle seat can be adjusted, thereby flexibly adapting to different vehicle turning scenarios and improving the user experience.

[0101] Figure 8 These are flowcharts of some embodiments of vehicle seat adjustment methods, such as... Figure 8 As shown, the vehicle seat adjustment method includes the following steps:

[0102] Step S801: Determine whether the seat rocking reduction function of the vehicle seat is turned on; if yes, proceed to step S802; otherwise, end the process; wherein, the seat rocking reduction function is to control the seat adjustment mechanism so that the seat can better absorb and disperse vibration energy when the vehicle is in motion, thereby reducing the swaying amplitude of the seat.

[0103] Step S802: Determine whether navigation information has been read; if yes, proceed to step S803; otherwise, proceed to step S804; wherein, navigation information can be read based on the application programming interface (API) provided by the navigation application on the user's mobile device, or obtained from the vehicle navigation system.

[0104] Step S803: Obtain road information for the vehicle in a preset future time period. This road information can be used to characterize the road conditions and driving status (straight or turning) of subsequent vehicles; proceed to step S805.

[0105] Step S804: Obtain road information based on the turn signal and the image information collected by the forward-looking camera; proceed to step S805.

[0106] Step S805: Calculate the turning radius of the vehicle when it turns in the future time period.

[0107] Step S806: Determine the reference height difference of the vehicle seat based on the turning radius. The correspondence between the reference height difference and the turning radius can be found in the above embodiment, and will not be repeated here.

[0108] Step S807: Control the seat adjustment motor to rotate according to the reference height difference. The specific method of controlling the seat adjustment motor can be found in the above embodiment, and will not be repeated here.

[0109] Step S808: Obtain the current height difference between the two sides of the vehicle seat. Specifically, the actual current height difference can be calculated based on the measurements from the height sensors on both sides of the vehicle seat.

[0110] Step S809: Obtain the seat anti-rocking function intensity set by the user. The user can set the intensity of the seat height adjustment difference via a preset button. S809 and S808 have no specific execution order and can be executed simultaneously.

[0111] Step S810: When the vehicle reaches the turning section, obtain the vehicle speed and steering wheel angle.

[0112] Step S811: Based on steps S809 and S810, determine the target height difference. Specifically, a more accurate target height difference can be determined using real-time vehicle speed and the turning radius determined in real-time based on the steering wheel angle. Then, combined with the user-set anti-roll function intensity, the calculated height difference is reduced to obtain a target height difference that meets the user-set intensity. It should be noted that the reference height difference calculated in step S806 is a theoretical calculation based on curvature information performed before the vehicle reaches the turning section. The purpose of calculating the reference height difference is to facilitate the seat adjustment mechanism in advance to adjust the seat height based on this reference height difference. The target height difference calculated in this step is a theoretical height difference derived from the actual curvature of the vehicle when it is actually driving on a turning section, the vehicle speed, and the user-set seat adjustment intensity. This provides a more accurate theoretical value of the height difference when the vehicle has reached the turning section, allowing for further height adjustment of the vehicle seat based on this target height difference to accommodate the actual curvature of the turning section and the user-set adjustment intensity requirements.

[0113] Step S812: Determine whether the absolute value of the difference between the target height difference and the current height difference is within the preset difference range; if yes, proceed to step S813; otherwise, proceed to step S814.

[0114] Step S813: Keep the seat adjustment motor in its current position.

[0115] Step S814: Determine whether the target height difference is greater than the current height difference. If yes, proceed to step S815; otherwise, proceed to step S816.

[0116] Step S815: Control the seat adjustment motor to rotate n revolutions in the opposite direction. This n value is the function calibration value, which is confirmed based on the motor selection and transmission speed ratio selection.

[0117] Step S816: Control the seat adjustment motor to rotate n times in the positive direction.

[0118] Step S817: Confirm vehicle use complete / seat rocking function turned off.

[0119] In some embodiments, the implementation of this embodiment, from a hardware perspective, can consist of a sensing system, a control system, an execution system, and other structures. For example, the sensing system may include: a vehicle speed sensor, a steering wheel angle sensor, seat height sensors (there may be two), a forward-facing camera, and an in-vehicle navigation system. The control system may include: a switch for providing seat auxiliary centripetal force and adjustment of auxiliary centripetal force intensity; the execution system may include: a drive motor; other structures may include: a fixed support, bearings, a motion support, a drive gear, a transmission gear, a drive shaft, and a limit pin; the software level may consist of a motion control algorithm based on the steps S801 to S817 described above.

[0120] In particular, in some embodiments, a function control switch panel for vehicle seat adjustment is also provided. Figure 9 This is a schematic diagram of a function control switch panel for vehicle seat adjustment in some embodiments. Figure 9As shown, the function control switch panel includes: a cornering assist function button 901, a cornering assist function adjustment level button 902, a cornering assist function first fixed level button 903, a cornering assist function second fixed level button 904, and a cornering assist function third fixed level button 905. The cornering assist function button 901 provides an ON button (labeled "ON") and an OFF button (labeled "OFF"). When the user selects the ON button, the cornering assist function is activated, allowing for seat height difference adjustment during vehicle turns to improve user comfort. When the user selects the OFF button, the vehicle seat height difference remains at 0 during turns. The cornering assist function adjustment level button 902 provides an UP (corresponding to the upper triangle in the diagram) and DOUP (corresponding to the lower triangle in the diagram) button. By selecting the UP or DOUP button, the user changes the intensity of the seat height difference adjustment (intensity range from 0% to 100%). Additionally, the user can select a fixed intensity of the seat height difference adjustment by choosing either the first fixed gear button 903, the second fixed gear button 904, or the third fixed gear button 905 for the cornering assist function. In some embodiments, the final target value of the height difference between the left and right sides of the seat during cornering can be the height difference required for the seat's lateral force to fully provide centripetal force under the actual curvature information multiplied by the user-set intensity of the seat height difference adjustment.

[0121] The steps S801 to S817 above predict vehicle turning based on road information. When it is predicted that the vehicle will turn, the seat adjustment is performed in advance according to the curvature information of the vehicle turning, so as to reduce the delay of the vehicle seat height difference adjustment and avoid the false triggering of seat adjustment when changing lanes on a straight road.

[0122] Overall, this embodiment proposes a solution that integrates in-vehicle navigation, turn signal signals, forward-facing camera equipment, and seat adjustment mechanism. This overcomes the problem of misjudgment in existing seat adjustment mechanisms, improves the accuracy and precision of seat adjustment, and enhances passenger comfort during vehicle cornering. Furthermore, based on the motion characteristics of vehicles during cornering, this embodiment proposes a corresponding seat adjustment mechanism structure and operating algorithm. By tilting the seat support surface through a controllable motion mechanism, a lateral force is applied to the human body to support circular motion, demonstrating significant application potential in passenger cars and commercial buses.
