Description

Technical Field

[0001] This invention relates to the field of automotive intelligent cockpit technology, and more specifically, to a control method, device, electronic device, and storage medium for vehicle interior. Background Technology

[0002] With the continuous development of intelligent technology, most cars nowadays are equipped with intelligent cockpits to enhance the driving experience. In an intelligent cockpit, relevant interior components can be adjusted as needed. For example, the steering wheel can be retracted into the center console to increase the space in the driver's cabin.

[0003] However, the control logic of the relevant interior components is not yet perfect, and it is impossible to achieve real-time monitoring and adjustment. When interference with external objects occurs during movement, it is impossible to avoid system damage or occupant injury in time. In order to achieve real-time monitoring and adjustment, it is usually necessary to add sensors to collect motion data of relevant interior components, which is not conducive to the integrated design of smart cockpit.

[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of the present invention, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0011] In some embodiments, the driving force is adjusted based on the position difference, the mass of the interior component, the interference force acting on the interior component, and the internal impedance of the interior component; the driving force is proportional to the position difference, the mass of the interior component, the interference force acting on the interior component, and the internal impedance of the interior component.

[0012] In some embodiments, after reducing the driving force, when it is detected that the current motion trajectory does not match the target motion trajectory, the control method further includes: determining whether the reduced driving force has reached a preset minimum value; if so, stopping the provision of driving force to stop the interior component from moving, and locking the interior component at the stopping position of the interior component; if not, returning to reducing the driving force until the interior component moves to the target position.

[0015] In some embodiments, in the autonomous driving mode, the control method further includes: detecting the vehicle's driving control signals; when an emergency braking signal is detected, generating an emergency deployment signal to control the steering component, wherein the emergency deployment speed of the emergency deployment signal is greater than the movement speed of the first interior use signal, and the locking position of the emergency deployment signal exceeds the target position of the first interior use signal; and according to the emergency deployment signal, controlling the steering component to deploy to the locking position, and deploying the airbag on the steering component during the emergency deployment process.

[0034] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided to fully and completely convey the concept of the exemplary embodiments to those skilled in the art.

[0035] The accompanying drawings are merely illustrative of the invention and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and therefore repeated descriptions of them will be omitted. Some block diagrams shown in the drawings are functional entities and do not necessarily correspond to physically or logically independent entities. These functional entities can be implemented in software, in one or more hardware modules or integrated circuits, or in different network and / or processor devices and / or microcontroller devices.

[0036] Furthermore, the processes shown in the accompanying drawings are merely illustrative and do not necessarily include all steps. For example, some steps can be broken down, some steps can be combined or partially combined, and the actual execution order may change depending on the actual situation. The terms "first," "second," and similar terms used in the specific description do not indicate any order, quantity, or importance, but are only used to distinguish different components. It should be noted that, unless otherwise specified, embodiments of the present invention and features in different embodiments can be combined with each other.

[0037] The present invention discloses a vehicle interior control method for controlling the movement of vehicle interior components between a use state and a storage state. The interior components referred to in this invention are movable components, specifically including a foldable steering wheel, a retractable steering column, and movable seats. The interior components are connected to the vehicle's sensor components and electronic control unit, enabling stable and accurate movement under the monitoring of the sensor components and the control of the electronic control unit.

[0038] When in use, the interior components are accessible to the driver for normal operation; when stowed, the driver does not need to operate the interior components, increasing the space in the cockpit and facilitating non-driving operations such as entertainment and business.

[0039] A foldable steering wheel may specifically include a body and a folding section, with the folding section connected to the body via a folding connector. The interior trim may also include a folding motor that drives the steering wheel to fold, and the folding motor is connected to the folding connector. The folding connector may specifically consist of a hinge or other folding structural components. The steering wheel may also be equipped with a hands-off detection device to monitor whether the driver's hands are accurately maneuvering the steering wheel in driver control mode.

[0040] The retractable steering column is connected to the body of the foldable steering wheel; the interior trim also includes a telescopic motor that drives the steering column to extend and retract, and the telescopic motor is connected to the steering column.

[0041] The movable seats are mounted inside the vehicle via a sliding rail mechanism; the interior components also include a sliding motor that drives the seats, which is connected to the sliding rail mechanism. The seats can move forward and backward and can also rotate as needed. The seats are not limited to the driver's seat, but also include other passenger seats.

[0042] The sensor assembly can utilize existing sensors in automotive smart cockpits, such as cameras used to monitor occupant status. When interior components undergo state transitions, the sensor assembly can rotate to face the component, enabling real-time monitoring of its movement and allowing for adjustments based on the specific scenario. The sensor assembly also responds promptly to interference from external objects, ensuring stable and accurate movement, preventing damage, and protecting occupants. Furthermore, when interior components are in use or stowed, the sensor assembly can rotate to face other monitored objects, such as occupant monitoring, enabling time-division multiplexing of the sensor assembly, improving the integration of the vehicle interior, and simplifying structural design.

[0043] The sensor assembly may specifically include at least one TOF (Time of Flight) camera installed inside the vehicle. The TOF camera has the ability to acquire three-dimensional spatial data inside the vehicle and can instantly reconstruct the interior space model and occupant model by acquiring depth information, thereby achieving accurate detection.

[0044] The Electronic Control Unit (ECU) is connected to the drive motors of the interior components, specifically including a folding motor that drives the steering wheel to fold, a telescopic motor that drives the steering column to extend and retract, and a sliding motor that drives the seats to move, so as to adjust the movement of the interior components in real time based on the data detected by the sensor components.

[0045] In one embodiment, the interior trim components may have multiple retractable states. For example, the retractable states include a first retractable state and a second retractable state, where the retractable travel of the first retractable state is greater than that of the second retractable state. Thus, the interior trim components can be controlled to retract to different retractable states in different driving modes. For example, in autonomous driving mode, the interior trim components are controlled to retract to the first retractable state, i.e., the fully retracted state; in parking waiting mode, the interior trim components are controlled to retract to the second retractable state, i.e., the partially retracted state, to facilitate vehicle restart.

[0046] In this invention, the vehicle equipped with the aforementioned movable interior components is specifically an autonomous driving vehicle. The steering wheel of this autonomous driving vehicle can be equipped with trigger buttons for both the retracted and usable states to facilitate driver operation of the interior components. The electronic control unit can automatically control the movement of the interior components according to the driving mode, and the driver can also trigger the movement of the interior components as needed. During vehicle operation, the retracted state trigger button is only activated in autonomous driving mode to ensure driving safety and prevent accidental retraction of the interior components due to improper driver operation. The usable state trigger button is activated in any driving mode, allowing the driver to take over the vehicle at any time as needed. Of course, the retracted state trigger button can also be activated during non-driving operations where driver operation of the interior components is not required, such as in parking mode.

[0047] The control method for the vehicle interior is described in detail below. Specifically, the control method for the vehicle interior of this invention is executed by the vehicle's electronic control unit.

[0048] Figure 1 The main steps of a vehicle interior control method in one embodiment are shown, with reference to Figure 1As shown, the control method includes: step S110, generating an interior control signal according to the vehicle's driving mode, the interior control signal carrying parameter information representing the driving force, target motion trajectory, and target position; step S120, driving the vehicle's interior components to switch between a use state and a storage state through the driving force; step S130, monitoring the current motion trajectory of the interior components, maintaining the driving force until the interior components move to the target position and then locking it when the current motion trajectory matches the target motion trajectory, and intervening in the driving force by impedance when the current motion trajectory does not match the target motion trajectory.

[0049] The driving force is used to control the force transmitted from the electronic control unit to the drive motor of the interior components, which drives the interior components to move. The driving force can be a system-preset force that ensures stable movement of the interior components. In some embodiments, a predetermined driving force mode is also preset in the vehicle system. When the current movement trajectory matches the target movement trajectory, this predetermined driving force mode can be maintained until the interior components move to the target position and then lock. In the predetermined driving force mode, the driving force may remain unchanged or may vary according to a preset mode to ensure stable movement of the interior components.

[0050] The target motion trajectory can be set to the target motion amount at preset time intervals, such as the target motion amount every 50ms. The target position is the final locked position of the interior component. In the storage state, the target position is the final unfolded position; in the use state, the target position is the final stored position.

[0051] Monitoring the current movement trajectory of interior components can be achieved using sensor components. These sensors collect motion data of the interior components in real time and provide it to the electronic control unit (ECU). The ECU then determines whether the current movement trajectory of the interior component matches the target movement trajectory. For example, the ECU checks every 50ms whether the current movement of the interior component is equal to the target movement at that moment. If they are equal, the current movement trajectory is considered to match the target trajectory; otherwise, it is considered not to match.

[0052] When the current motion trajectory of the interior component matches the target motion trajectory, the driving force is maintained according to the preset driving force pattern, causing the interior component to move along the target motion trajectory to the target position and then lock. It should be noted that when the interior component includes multiple parts, the interior control signal includes multiple signals corresponding to each part, and the state switching of each part depends on the structural relationship between the parts and can be performed time-sharingly or synchronously. For example, if the interior component includes a steering wheel, steering column, and seat, the interior control signal carries parameter information representing the driving force, target motion trajectory, and target position of the steering wheel, steering column, and seat, respectively. The interior control signal includes interior use signals and interior storage signals. Under the interior use signal, the steering wheel unfolding must wait for the steering column to extend completely, and the seat movement can be synchronized with the steering wheel / steering column movement; under the interior storage signal, the steering column retraction must wait for the steering wheel to fold completely, and the seat movement can be synchronized with the steering wheel / steering column movement. Of course, if the extension or retraction of the steering column does not interfere with the movement of the steering wheel, the steering wheel and steering column can also move synchronously.

[0053] When the current movement trajectory of the interior components does not match the target movement trajectory, including situations where the interior components are lagging or leading, the electronic control unit needs to intervene with impedance to the driving force to avoid damage to the interior components or injury to the occupants. By monitoring the current movement trajectory of the interior components in real time, adjustments can be made promptly when the current movement trajectory of the interior components does not match the target movement trajectory, ensuring that the interior components move stably and accurately to the target position. The vehicle's driving mode can be determined by the electronic control unit based on driving data collected by multiple sensors, and existing technologies can be used; this invention does not limit this.

[0054] Figure 2 This shows the interior control diagrams for different driving modes. Figure 2 As shown, the vehicle's driving modes include, for example, from vehicle start-up to stop: Start-up mode S210, Driver mode S220, Autonomous driving mode S230, and Parking mode S240. Before Parking mode S240, depending on the configuration of different autonomous driving levels, driver intervention may be required, which is not specifically shown in the figure. Interior control signals include interior use signals and interior storage signals; in Start-up mode, an interior use signal is generated; in Driver mode, the interior is kept in use; in Autonomous driving mode, an interior storage signal is generated; in Parking mode and after parking, the interior is kept in storage. Of course, referring to the above embodiment, the storage state of the interior components in Autonomous driving mode S230 and Parking mode S240 may be different, which will not be repeated here. In the interior storage state, if the electronic control unit determines that the driver needs to take over the vehicle, it promptly generates an interior use signal to ensure that the interior is fully unfolded before the driver officially takes over the vehicle.

[0055] Figure 3 The steps for impedance intervention of the driving force are shown in the embodiment, refer to Figure 3 As shown, in this embodiment, the current movement trajectory of the interior component is monitored in step S130a. When the current movement trajectory matches the target movement trajectory, the driving force is maintained until the interior component moves to the target position and then locked in step S130b. When the current movement trajectory does not match the target movement trajectory, the driving force is resisted in step S130c. Step S130c specifically includes: S310, obtaining the position difference between the current movement trajectory and the target movement trajectory at the current moment; S320, when the current movement trajectory lags behind the target movement trajectory, the driving force is increased according to the position difference, and the process returns to step S130a to monitor the current movement trajectory of the interior component; S330, when the current movement trajectory leads the target movement trajectory, the driving force is decreased according to the position difference, and the process returns to step S130a to monitor the current movement trajectory of the interior component.

[0056] Based on the current motion of the interior component and the corresponding target motion, the distance deviation (position difference) between the current trajectory and the target trajectory in the forward direction of the interior component can be calculated. If the current trajectory lags behind the target trajectory, it indicates that the interior component may be obstructed. Therefore, the driving force is increased according to the position difference to accelerate the movement of the interior component. If the current trajectory leads the target trajectory, it indicates that the interior component may be being pulled. Therefore, the driving force is decreased according to the position difference to slow down the movement of the interior component.

[0057] The driving force can be adjusted based on the position difference, the mass of the interior components, the interference force acting on the interior components, and the internal impedance of the interior components. The mass and internal impedance of the interior components are set values, and the interference force acting on the interior components can be obtained through relevant mechanical sensors. The driving force is directly proportional to the position difference, the mass of the interior components, the interference force acting on the interior components, and the internal impedance of the interior components. Existing mechanical calculation methods can be used to calculate the driving force, and this invention does not impose any limitations on this.

[0058] Figure 4 The illustrated embodiment demonstrates the control process where, even after increasing the driving force, the target motion trajectory is not reached. After increasing the driving force, the process returns to continuously monitoring whether the current motion trajectory of the interior components matches the target motion trajectory. When it is detected that the current motion trajectory does not match the target motion trajectory, [further steps are taken]. Figure 4The control method, indicated by the bolded arrow, further includes: Step S410, determining whether the increased driving force has reached a preset maximum value. If the driving force has reached its maximum value, then Step S420 is executed to stop providing driving force to stop the interior components from moving, and the number of stops is recorded. Stopping the provision of driving force means that the driving force becomes zero. After stopping the provision of driving force, the interior components may continue to move a short distance under inertia before stopping. Stopping the provision of driving force can avoid danger, for example, at this time, the occupant's body may be blocking the movement of the interior components. If the driving force is continuously increased, it will damage the interior components on the one hand, and may also cause injury to the occupant on the other hand. When the recorded number of stops is less than the preset number, a preset time can be waited, such as 10 seconds. During the waiting period, the occupant can be reminded to avoid the obstacle through voice / display, and then the interior control signal is reset. When the number of stops reaches the preset number, such as the second stop, it may correspond to the occupant not wanting the interior components to change their state, or there is an unavoidable obstacle in the direction of the interior components' movement. In this case, Step S430 is executed to control the interior components to move in the opposite direction. If the driving force does not reach its maximum value, the driving force is increased, and the system returns to monitoring the movement of interior components.

[0059] Figure 5 The process of controlling the reverse movement of the interior components in the embodiment is shown, with reference to Figure 5 As shown, when the number of stops reaches a preset number, the interior component is controlled to move in the reverse direction, including: step S510, generating a reverse control signal based on the current position of the interior component, the reverse control signal carrying parameter information representing the reverse driving force, the reverse movement trajectory, and the initial position; step S520, determining whether the interference force acting on the interior component is less than a preset value; if so, step S530 is executed, maintaining the reverse driving force, controlling the interior component to move along the reverse movement trajectory to the initial position and then locking it; otherwise, step S540 is executed, stopping the provision of driving force to stop the interior component from moving, and locking the interior component at the stopping position of the interior component.

[0060] Interference force refers to the force exerted by external objects, i.e., obstacles (including human bodies and objects), on interior components. When the interference force acting on the interior components is determined to be less than a preset value, the reverse driving force can be maintained in a preset reverse driving force mode. In the preset reverse driving force mode, the reverse driving force may remain unchanged or may change according to the preset mode to ensure stable movement of the interior components.

[0061] Depending on the type and location of the obstacle, the reverse control signal can be adjusted appropriately based on the interior control signal. Specifically, when the current trajectory lags behind the target trajectory, the type and location of the obstacle acting on the interior components can be detected by the sensor components; thus, the electronic control unit determines the preset maximum value for increasing the driving force, as well as the relationship between the speed of the reverse trajectory and the speed of the target trajectory, based on the type and location of the obstacle.

[0062] The types of obstacles include human bodies and objects, and the positions include clamping positions and blocking positions. In human body clamping mode, the speed of the reverse movement trajectory is controlled to be greater than the speed of the target movement trajectory to quickly restore the interior components to their initial position and avoid injury to the human body; in other obstacle modes, including object clamping mode, human body blocking mode, and object blocking mode, the speed of the reverse movement trajectory can be slightly less than the speed of the target movement trajectory to control the interior components to stably restore their initial state.

[0063] The scenarios corresponding to the human body clamping mode include, for example, a driver's finger being caught in an interior component; the scenarios corresponding to the object clamping mode include, for example, a work badge hanging on the driver's chest being caught in an interior component; the scenarios corresponding to the human body blocking mode include, for example, a driver pushing an interior component with their palm, blocking its normal movement; and the scenarios corresponding to the object blocking mode include, for example, an interior component being blocked by a sun visor inside the vehicle. Of course, the human body clamping mode, object clamping mode, human body blocking mode, and object blocking mode also include other scenarios, which will not be repeated here.

[0064] When the obstacle is a human body, the maximum value of the driving force is lower than the maximum value when the obstacle is an object, to avoid excessively increasing the driving force and causing injury to the human body. Specifically, in human body clamping mode, the maximum value of the driving force is set to F. max =F1; In object clamping mode, the maximum driving force is set to F. max =F2; In human body blocking mode, the maximum driving force is set to F. max =F3; In object blocking mode, the maximum driving force is set to F. max =F4; F1 < F2 < F3 < F4. This avoids both personal injury and system damage caused by excessively rapid retraction of interior components in clamping mode.

[0065] After locking the interior trim components in the stop position, the retraction / deployment of the interior trim components can continue according to the trigger button.

[0066] Figure 6The illustrated embodiment shows the process of reducing driving force when the current motion trajectory leads the target motion trajectory. After reducing the driving force, it returns to continue monitoring whether the current motion trajectory of the interior components matches the target motion trajectory. When it is detected that the current motion trajectory leads the target motion trajectory, it refers to... Figure 6 The control method, indicated by the bold arrow, further includes step S610, determining whether the reduced driving force has reached a preset minimum value. This minimum value is a force value greater than zero but less than the initial preset value of the driving force. If so, step S620 is executed to stop providing the driving force to stop the interior component from moving and to lock the interior component at its stop position. By setting the minimum value of the driving force, the interference force applied to the interior component by external objects can be indirectly limited, that is, the influence of the interference force on the movement of the interior component can be limited, preventing the interior component from being damaged by excessive interference force. Otherwise, the driving force is reduced, and the movement of the interior component is continuously monitored until the interior component moves to the target position. For example, if an occupant applies a force in the same direction as the movement of the interior component to accelerate its movement, the driving force of the system is reduced according to the force required for the movement of the interior component, combined with the already applied interference force, so that the movement speed of the interior component returns to normal. If the interior component is still accelerating and the driving force has been reduced to the minimum, the interior component is stopped in an emergency to avoid damage to the system.

[0067] The aforementioned control method for vehicle interior components enables real-time adjustment of the component's movement based on actual scenarios, ensuring stable and accurate movement. It also allows for timely responses when the interior components interfere with external objects, preventing damage, occupant injury, and enhancing the user experience.

[0068] Furthermore, in one embodiment, combined with Figure 7 The state of the interior components shown before vehicle startup and Figure 8 The diagram shows the state of the interior components after vehicle startup. The interior components include a movable steering assembly 101 and a movable driver's seat 103. In startup mode, the control method further includes: detecting the seatbelt and seating pressure of the driver's seat 103; when a seatbelt tightening signal is detected, generating a first interior usage signal to control the steering assembly 101; and generating a second interior usage signal to control the driver's seat 103 based on a preset mapping relationship between seating pressure and the movement distance of the driver's seat 103. Thus, in... Figure 7 As shown in the pre-start state, the driver's seat 103 is relatively far from the steering assembly 101, facilitating entry and exit from the vehicle. Once the driver is seated and fastens their seatbelt, the system triggers the automatic deployment of the steering assembly 101 to ensure driving safety. Based on the pressure applied when sitting down, the system estimates the driver's body size and adjusts the driver's seat 103 accordingly. The adjusted state is as follows: Figure 8As shown, the steering assembly 101 is fully deployed, and the driver's seat 103 moves to a suitable position without requiring manual adjustment by the driver. The mapping relationship between seating pressure and the movement distance of the driver's seat 103 can be pre-stored in the system to enable appropriate adjustment of the driver's seat 103 according to different seating pressure ranges.

[0069] In one embodiment, in autonomous driving mode, the control method further includes: detecting vehicle driving control signals; when an emergency braking signal is detected, generating an emergency deployment signal to control the steering component, wherein the emergency deployment speed of the emergency deployment signal is greater than the movement speed of the first interior use signal, and the locking position of the emergency deployment signal exceeds the target position of the first interior use signal; according to the emergency deployment signal, controlling the steering component to deploy to the locking position, and deploying the airbag on the steering component during the emergency deployment. The driving control signal is generated by the electronic control unit according to preset autonomous driving control logic, and the present invention does not limit this. In autonomous driving mode, when a vehicle condition requiring emergency braking is detected, and there is no time to wait for the driver to take over, the electronic control unit will generate an emergency braking signal. However, at this time, the steering component is in a retracted state, the distance between it and the driver is far, and the driver is in a relaxed state of non-driving operation, which may result in a violent collision forward due to the sudden emergency braking of the vehicle, causing impact injury or traction injury to body parts. Therefore, the electronic control unit immediately generates an emergency deployment signal to control the steering component, causing the steering component in the retracted state to deploy at a faster emergency deployment speed than normal deployment to a locking position that is farther away and closer to the driver's position than normal deployment. During the emergency deployment, the airbag is deployed to protect the driver's safety in emergency braking scenarios during autonomous driving by using the airbag that is close to the driver.
