Description

Technical Field

[0001] This application belongs to the field of touch technology, and in particular relates to a control and guidance method, an automobile, and a computer-readable storage medium. Background Technology

[0002] With the development of automotive intelligence, steering wheels are integrating more and more functions, such as volume control, cruise speed setting, and instrument menu switching. These functions often use touch swipe operations to improve the intuitiveness of the interaction. However, the touch area on the steering wheel is usually curved or irregularly shaped, and due to structural design limitations, the signal strength of touch sensors (such as capacitive touch matrices) is weaker in the edge areas. When a user's finger slides to the edge area, the system often cannot reliably recognize the sliding trajectory, leading to false triggering of functions or operation failure.

[0003] Existing solutions include increasing the touch area, improving sensor sensitivity, or using vibration alerts. However, these methods are either limited by the steering wheel structure, prone to increasing false alarm rates, or only provide a single vibration alarm after the finger leaves the effective area, failing to guide the user to remain within a high-recognition-rate area in real time during the swipe. Therefore, how to guide users to correctly control the steering wheel is a technical problem that urgently needs to be solved by those skilled in the art.

[0028] Existing control methods, especially touch operation, often rely on visual feedback to confirm the validity of the operation. However, in driving scenarios, drivers need to continuously pay attention to the road, which leads to a lack of reliable non-visual confirmation mechanisms for touch operation. Therefore, existing touch operation has the following technical pain points: (1) Difficulty in blind operation: During driving, users need to keep their eyes on the road conditions, making it difficult to confirm whether the operation has been correctly recognized and executed by the system while touching and sliding, resulting in increased uncertainty in operation. (2) Single feedback information: Existing technologies usually only provide a single vibration confirmation when a touch occurs, and cannot inform the user of the intermediate state of the operation or the execution result (success / failure). (3) High risk of misoperation: When driving on bumpy roads, the user's finger may unconsciously slide or slide out of the effective area, which can easily lead to accidental triggering. Existing anti-misoperation solutions mostly use simple area locking or a single alarm vibration, which lacks dynamic guidance capabilities. How to improve the efficiency of touch operation has become an urgent problem to be solved. In this regard, this application proposes a touch guidance method. For a clear description of the method provided in this embodiment, please refer to Figure 1 This includes steps S110 to S130.

[0029] In one embodiment, the method provided in this application is applied to a touch panel, with a vibration motor located beneath the touch panel. When a user's finger touches the touch panel, the touch panel can acquire corresponding touch signals, including but not limited to touch coordinates, sliding trajectory, pressure value, and sliding speed, for subsequent processing. The vibration motor is located below or around the touch panel and can generate multi-frequency, multi-intensity tactile feedback signals, i.e., vibration. There can be one or more vibration motors, and multiple motors can work together to achieve spatially directional vibration guidance. The number and installation position of the vibration motors are not limited in this application. For the application scenario of this application, the touch panel can be mounted on a car steering wheel. That is, while driving, the user can blindly operate the touch panel on the steering wheel with their fingers to turn specific vehicle functions on, off, or switch them.

[0030] Step S110: Determine whether the start-up conditions are met based on the obtained touch signal.

[0031] In one implementation, it is understood that, in the context of blind steering wheel operation, when a user holds the steering wheel, their fingers are naturally placed in the commonly used operating areas near the 3 o'clock and 9 o'clock positions, i.e., on or near the touch panel. During driving, users frequently swipe near the touch panel, but their intention is to operate the steering wheel, not to interact with the touch panel. Therefore, to avoid accidental touches or activations, activation conditions can be set. The touch signals obtained from the touch panel are used to determine whether the preset activation conditions are met, i.e., to determine whether the user intends to interact with the touch panel.

[0032] In one embodiment, the activation conditions include: the touch signal is located within a preset recognition area; and / or, the duration of the touch signal is greater than a preset time threshold; and / or, the signal strength value of the touch signal is acquired, and the signal strength value is greater than a preset strength threshold.

[0033] In one embodiment, the activation condition can be any one of the following conditions, or a combination thereof. These include the touch signal being located within a preset recognition area; and / or the duration of the touch signal being greater than a preset time threshold; and / or acquiring the signal strength value of the touch signal, wherein the signal strength value is greater than a preset strength threshold.

[0034] Understandably, in the context of a steering wheel application, the touch panel is a curved surface covering the steering wheel. There is a gradient distribution of recognition rate on the touch panel surface, with the strongest signal in the central area and significant signal attenuation at the edges. This characteristic is particularly pronounced on curved surfaces. Therefore, layered recognition areas can be preset on the touch panel, dividing the curved surface into recognition and non-recognition areas. The recognition area corresponds to the central band of the curved surface where the signal strength is above a threshold, while the non-recognition area covers the edges of the curved surface where the signal attenuates significantly. Thus, the system only determines that the activation condition is met when the touch signal falls into the recognition area; otherwise, the trigger signal is ignored.

[0035] Furthermore, the recognition criteria also include the duration of the touch signal. It's understandable that touch operations typically require maintaining contact for a certain duration and completing specific trajectory drawing to be recognized as valid. Therefore, setting a time threshold can filter out momentary jitter or unintentional touches. That is, only when the duration of the touch signal exceeds a preset time threshold (e.g., 150ms) will the activation condition be met; otherwise, it is considered an invalid touch.

[0036] Furthermore, identification can also be based on the signal strength of the touch signal. It's understandable that the pressure applied by a user during intentional operation is usually significantly higher than that of an unintentional touch or slight rubbing. The signal strength of the touch signal can be used to determine whether the user intends to interact. Specifically, when a user's finger slides on the touch panel, the system acquires the signal strength value and reference strength value at the touch point in real time and calculates the delta value. Signal Strength: The sensor's raw measurement value at the current moment. Finger touch increases capacitance, causing the signal value to rise. It reflects the real-time reading of the sensor's current state. Reference Strength: A long-term average value representing the sensor's baseline state when not touched. It adjusts slowly with environmental changes. It serves as a baseline for comparison, filtering out environmental drift. Delta, obtained by subtracting Reference from Signal, is the core data for this trigger condition identification, representing the actual amount of signal change caused by the touch.

[0037] The determination of whether the activation condition is met is based on whether the Delta value is greater than a preset strength threshold (DetectThreshold). When there is no touch, the signal strength (Signal) ≈ Reference, and Delta ≈ 0. The range of values ​​for Signal and Reference is predetermined (generally greater than 2000). They are dimensionless, and their absolute values ​​do not have direct physical meaning (e.g., picofarads). The key is their relative difference. When there is a touch, the Reference remains relatively constant, while the Signal strength increases significantly, so Delta also increases significantly. When the Delta value exceeds the DetectThreshold (e.g., 800), the activation condition is considered met; otherwise, the touch is ignored.

[0038] As mentioned above, the three conditions can be combined in any way according to actual needs to determine whether a response to touch operations is required.

[0039] In other embodiments, the aforementioned activation conditions are all based on the touch itself. In this embodiment, multi-source vehicle state data such as steering wheel rotation angle, vehicle speed, and acceleration can also be combined to determine whether the activation conditions are met. It is understandable that users have limited attention spans while driving; performing complex touch operations at high speeds or during sharp turns is not only difficult but may also pose safety hazards. Therefore, vehicle state can also be incorporated into the activation conditions. Touch function activation is only allowed when the vehicle state meets a preset stable state. This stable state can be a combination of conditions such as vehicle speed within a preset range, steering wheel rotation rate below a threshold, and both longitudinal and lateral acceleration below safety limits.

[0040] Step S120: When the start-up conditions are met, obtain the control information based on the touch signal, control the vibration motor to output a vibration signal, and use the vibration signal to guide the user's touch.

[0041] In one embodiment, when the activation conditions are met, i.e., the user is deemed to have begun touch operation, the vibration motor can be activated to output a vibration signal, providing tactile feedback to guide the finger in real time. This vibration signal can output different signals (e.g., amplitude, frequency) depending on different conditions and situations, guiding the user through vibration. Specific vibration modes will be discussed in detail later.

[0042] In one embodiment, acquiring touch signal-based control information and controlling the vibration motor to output a vibration signal includes: matching a prompt mode according to the control information, wherein the prompt mode includes at least one of a boundary prompt mode, a validity prompt mode, and a progress prompt mode; and controlling the vibration motor to output a vibration signal based on the prompt mode.

[0043] In one embodiment, the prompting mode in this application includes at least one of a boundary prompting mode, a validity prompting mode, and a progress prompting mode. The boundary prompting mode guides the user to operate within the valid recognition area, preventing the user from sliding out of the recognition area and rendering the operation invalid. The validity prompting mode guides the user to perform valid operations, such as checking the correctness of the sliding path, the reasonableness of the sliding speed, and whether the pressure applied is sufficient. The progress prompting mode informs the user of the current operation's progress, such as the proportion of the sliding distance to the target area and the remaining steps. Different prompting modes can be arbitrarily combined, using the same vibration motor to achieve multi-mode multiplexing through timing modulation. Correspondingly, different prompting modes need to be matched according to the actual control information to determine which prompting mode is required.

[0044] In one embodiment, matching a prompt mode based on control information includes: acquiring the sliding direction, sliding speed, and touch position from the control information; matching a boundary prompt mode based on the touch position; and / or matching a validity prompt mode based on the sliding direction and sliding speed; and / or matching a progress prompt mode based on the sliding direction and touch position.

[0045] In one embodiment, the control information specifically includes data such as the sliding direction, sliding speed, and touch position input by the user when operating the touch panel. Different prompt modes are matched according to different control information.

[0046] Based on touch position matching boundary prompt mode, for example, when the touch position is close to the edge of the effective recognition area, the boundary prompt mode is activated to guide the user to operate within the effective recognition area and avoid sliding out of the effective area.

[0047] Based on the validity prompt mode of matching sliding direction and sliding speed, for example, when the deviation of the sliding direction from the preset path exceeds a threshold or the sliding speed is too fast / too slow, the validity prompt mode is activated, and the user is guided to adjust the sliding direction or reduce the speed through vibration signal to ensure that the operation meets the recognition requirements.

[0048] Based on the progress indication mode matching the sliding direction and touch position, the vibration signal informs the user of the current sliding progress. For example, if the operation is approaching the correctness, the vibration will become more stable or stronger; if the operation deviates, the vibration will weaken or become disturbed.

[0049] In one embodiment, when the prompt mode is a boundary prompt mode, the touch position in the operation information is obtained; the vibration motor is controlled to output a vibration signal based on the prompt mode, including: when the touch position is within a preset recognition area, the vibration motor is controlled to output a first vibration signal; when the distance between the touch position and the boundary of the recognition area is less than a threshold, the vibration motor is controlled to output a second vibration signal; when the touch position exceeds the recognition area, the vibration motor is controlled to output a third vibration signal.

[0050] In one implementation, the boundary prompt mode is primarily used to guide the user to operate within the valid recognition area, preventing them from sliding out of the recognition area and thus invalidating the operation. Therefore, it is necessary to obtain the touch position from the control information and determine the boundary based on the touch position and the preset recognition area.

[0051] When the touch position is within the preset recognition area, the vibration motor is controlled to output a first vibration signal. In this case, the user's operation is valid, so the user's operation can be left uninterrupted. Specifically, the first vibration signal may be no vibration or only a slight, steady confirmatory vibration signal.

[0052] When the distance between the touch position and the boundary of the preset recognition area is less than a threshold, it indicates that the user is about to slide out of the effective recognition area. At this time, the vibration motor is controlled to output a second vibration signal. Because the boundary prompt mode is used to inform the user that the operation is within the effective recognition range, the second vibration signal must be significantly more perceptible than the first vibration signal, which provides no prompt or only a slight prompt. That is, the second vibration signal can be a short pulse vibration with a distinct rhythm to enhance the user's timely perception of the boundary position. For cases where multiple vibration motors are set under the touch panel, spatial coding can also be used to make the second vibration signal respond only in a local area near the boundary, thereby achieving precise spatial positioning of tactile guidance. That is, the vibration motor at the corresponding position at the edge of the recognition area is activated individually, forming directional tactile guidance, allowing the user to intuitively perceive the direction of sliding out and naturally return to the correct operating path.

[0053] When the touch position exceeds the boundary of the preset recognition area, the vibration motor outputs a third vibration signal. At this point, the touch panel completely loses its ability to acquire touch signals, and understandably, the operation is completely ineffective. Therefore, the third vibration signal can be a stronger signal than the second vibration signal, not only informing the user that the operation has exceeded the boundary but also indicating that the operation has failed. Thus, the third vibration signal could be a strong, continuous low-frequency vibration that drives the entire steering wheel to convey an irreversible sense of termination.

[0054] It is understood that different vibration signals will be described and illustrated in the preceding and following text, but these are merely illustrative examples to facilitate differentiation between the signals and are not intended to limit the specific output form of the vibration signals. Actual vibration signals can be arbitrarily set according to practical needs, such as amplitude, frequency, duration, and waveform combinations; this application does not impose any restrictions on these. As long as they are sufficiently distinguishable to form a clear perception hierarchy, the guidance and feedback functions required by this solution can be achieved.

[0055] In one embodiment, when the prompt mode is a valid prompt mode, the sliding direction and sliding speed in the control information are acquired; the vibration motor is controlled to output a vibration signal based on the prompt mode, including: when the sliding speed is within a preset valid range and the sliding deviation value determined based on the sliding direction is less than a preset deviation threshold, the vibration motor is controlled to output a fourth vibration signal; when the sliding speed is not within the preset valid range, or the sliding deviation value is greater than or equal to the preset deviation threshold, the vibration motor is controlled to output a fifth vibration signal.

[0056] In one implementation, when the system detects a potential problem with the user's swipe operation (such as swiping too fast leading to low recognition confidence or swiping trajectory deviating from the expected path), it does not directly reject the operation. Instead, it prompts the user to adjust their operation through a specific vibration pattern and allows the user to continue correcting the operation within the same touch session. This mode is also known as the validity prompt mode. The purpose of this mode is to guide the user to input a more accurate swipe trajectory, rather than interrupting the interaction. Therefore, the validity of the operation is the core criterion for judgment.

[0057] The user's operation is considered valid when the sliding direction and speed in the control information are within a preset valid range, and the sliding deviation value determined based on the sliding direction is less than a preset deviation threshold. In this case, the output fourth vibration signal can be approximated by the first vibration signal, that is, confirmation is provided through no notification or slight notification, reflecting the system's tacit acceptance and approval of compliant operations. The sliding deviation value is obtained by calculating the difference between the user-input sliding trajectory and the preset ideal path, for example, by using Euclidean distance or dynamic time warping algorithms to quantify the degree of trajectory deviation. The ideal path can be a preset path that would normally trigger the function.

[0058] Conversely, if the sliding speed exceeds the preset effective range, or the sliding deviation value is greater than or equal to the preset deviation threshold, meaning either condition is not met, the operation is deemed insufficiently effective. In this case, the vibration motor outputs a fifth vibration signal. The fifth vibration signal can be similar to the second vibration signal mentioned earlier; that is, compared to the fourth vibration signal, the amplitude and frequency of the output vibration signal are increased to create a stronger perceptual cue, prompting the user to adjust the sliding rhythm or trajectory direction in a timely manner. Furthermore, for cases where multiple vibration motors are set under the touch panel, each motor can be driven independently according to a preset spatial mapping relationship to achieve regionalized and differentiated vibration feedback. For example, the ideal path is a straight line segment sloping upwards and to the right from the center. When the user's sliding trajectory is below this path, it has deviated from the ideal path. At this time, through spatial encoding, the motor on the ideal path is controlled to emit a fifth vibration signal. This creates a gradient feedback effect where the vibration signal is strongest on the ideal path, while the vibration intensity gradually decreases in areas far from the ideal path. This guides the user to naturally return to the ideal path through tactile guidance, avoiding abrupt interruptions and strengthening spatial orientation memory, thus ensuring the effectiveness of the user's sliding operation.

[0059] In one embodiment, when the prompt mode is a progress prompt mode, the sliding direction and touch position in the control information are obtained; the vibration motor is controlled to output a vibration signal based on the prompt mode, including: determining the sliding progress based on the sliding direction and touch position; and adjusting the output intensity of the vibration signal based on the sliding progress.

[0060] In one implementation, when the prompt mode is a progress prompt mode, it is used to inform the user of the current operation's progress. The sliding progress can be determined based on the sliding direction and touch position, for example, mapping the current touch position to the progress percentage in real time with the sliding start point as 0% and the end point as 100%. The output intensity of the vibration signal is adjusted according to the percentage corresponding to the sliding progress. For example, it can be set that the vibration tends to stabilize or increase as the operation becomes correct, and the vibration weakens or becomes disturbed as the operation deviates, thus forming an intuitive "haptic progress bar".

[0061] Step S130: When the control information meets the preset success conditions, generate and output control commands based on the success conditions.

[0062] In one implementation, the purpose of touch control is to trigger specific in-vehicle functions. Successful triggering depends on whether the control information meets preset success conditions. These success conditions can be the content of the input control information, matched with a specific swiping pattern. For example, the swiping pattern requires the duration, speed stability, and path deviation of the swiping trajectory within the effective area to be within a threshold range. The swiping pattern can also include operations such as clicking, long-pressing, or hard-pressing according to a specific function. The success conditions can be arbitrarily set according to actual needs and are not restricted.

[0063] In one embodiment, when the control information meets the preset success conditions, a control command is generated and output based on the success conditions, including: matching whether a corresponding preset sliding mode exists based on the control information; if the matching fails, controlling the vibration motor to output a failure prompt vibration signal; if the matching succeeds, it is determined that the success conditions are met; and controlling the vibration motor to output a success confirmation vibration signal; obtaining the target function corresponding to the preset sliding mode, and generating and outputting the control command.

[0064] In one implementation, success conditions can be defined using a sliding pattern. It is understood that success conditions are used to determine whether a user needs to trigger a specific function. Since in-vehicle functions can include multiple functions, there can also be multiple success conditions, each corresponding to a specific target function. Therefore, after each user input touch operation, the system can match the control information to determine if a corresponding sliding pattern exists. If a match is successful, the success condition is considered met, and the corresponding target function is retrieved based on the matching pattern, generating and outputting a control command. Furthermore, to inform the user of the validity of their input operation, a success confirmation vibration signal can be output from the motor simultaneously with the generation and output of the control command, indicating that the input operation has been accurately recognized and executed. Additionally, other vehicle notification components, such as voice and text / graphic components, can be requested to provide synchronous feedback, forming a multimodal confirmation loop; for example, a voice announcement of "volume turned up" can be accompanied by a dynamic change in the volume icon on the instrument panel, while a flexible LED strip on the steering wheel edge displays a progressively flowing blue light to indicate the completion of the operation.

[0065] Conversely, if the input control information does not match any preset sliding pattern, it is determined to be an invalid operation, and the control motor outputs a failure vibration signal to remind the user that the input operation is invalid. Similarly, other notification components of the vehicle can be requested to output failure information. For example, a voice prompt "Operation not recognized, please try again" may be displayed, a yellow exclamation mark icon may be displayed on the instrument panel, and a flexible LED light strip may flash red three times in sync to enhance the perception of failure.

[0066] Therefore, the method provided in this application is applied to a touch panel, which has a vibration motor underneath. The method includes the following steps: determining whether the activation condition is met based on the acquired touch signal; when the activation condition is met, acquiring control information based on the touch signal, controlling the vibration motor to output a vibration signal, which is used to guide the user's touch; when the control information meets a preset success condition, generating and outputting a control command based on the success condition. Therefore, this application can guide the user to accurately complete touch operations by outputting a vibration signal after the activation condition is met when the user touches the screen, allowing the user to accurately complete the target operation even without visual field, significantly improving interaction safety and operational efficiency. Setting activation conditions avoids accidental touches and ensures the effectiveness of input operations. It also ensures that the user can always complete the operation in a state of effective feedback, avoiding operation failure due to accidental touches or sliding deviations. Furthermore, the vibration signal output is divided into three prompting modes: a boundary prompting mode guides the user to operate within the effective recognition area, ensuring complete acquisition of control information; and a vibration feedback mode guides the user to actively keep their finger in a high signal intensity area, avoiding recognition interruption or failure due to sliding to a weak signal area at the edge, thus improving the recognition success rate. The validity prompt mode guides users to confirm that the current operation is within a valid sliding path, ensuring that users can input valid operation content. The progress prompt mode adjusts the vibration intensity in real time according to the input progress, allowing users to clearly perceive the completion status of the sliding. These prompt modes can be combined arbitrarily, enabling users to clearly understand the recognition stage and completion status of the current operation. Different vibration signals guide users to complete valid content input, ensuring the accuracy and efficiency of the operation. This allows users to accurately complete the required function input without observing the steering wheel, improving user convenience. Furthermore, success conditions are linked to target functions, allowing users to input different operation content to trigger diverse functions and meet personalized needs. In addition, while matching functions, the system also determines whether the operation was successfully triggered. Different vibration signals are output for both success and failure, providing timely feedback on the operation result and ensuring unambiguous understanding of the operation outcome. Moreover, by applying it to touch panels, it can adapt to various steering wheel surfaces, requiring only minor structural tactile boundary design without altering the overall steering wheel shape, ensuring the method's scalability and universality.

[0067] This application also provides an automobile, the steering wheel of which integrates a touch panel, the touch panel being used to implement the steps of the control guidance method described above.
