[0007] Determine a steering wheel change angle between the previous moment and the current moment based on the steering wheel steering data at the current moment and the steering wheel steering data at the previous moment;

[0008] In response to the steering wheel change angle being greater than a preset angle threshold, the displayed steering wheel icon is updated based on the steering wheel steering data at the current moment.

[0009] Optionally, the steering wheel steering data includes a steering wheel direction and a steering wheel angle, and based on the steering wheel steering data at the current moment and the steering wheel steering data at the previous moment, determining a steering wheel angle change between the previous moment and the current moment includes:

[0010] Determining whether the steering wheel orientation at the current moment is the same as that at the previous moment;

[0011] If they are the same, the steering wheel change angle between the previous moment and the current moment is determined based on the angle difference between the steering wheel angles at the current moment and the previous moment; otherwise, the steering wheel change angle between the previous moment and the current moment is determined based on the angle sum between the steering wheel angles at the current moment and the previous moment.

[0012] Optionally, the method further includes:

[0013] Obtain vehicle driving information;

[0014] Based on the driving information, it is determined whether the preset angle threshold satisfies a preset update condition; if so, the preset angle threshold is updated based on the driving information.

[0015] Optionally, judging whether the preset angle threshold satisfies a preset update condition based on the driving information includes:

[0016] Determining whether the driving road condition in the driving information is a preset road condition, or whether the driving working condition in the driving information is a preset working condition, and if so, determining that the preset angle threshold satisfies a preset update condition;

[0017] Updating the preset angle threshold based on the driving information includes:

[0018] A target threshold corresponding to the driving road condition or the driving working condition is obtained, and the preset angle threshold is updated based on the target threshold.

[0019] Optionally, judging whether the preset angle threshold satisfies a preset update condition based on the driving information includes:

When the steering wheel change angle is greater than the preset angle threshold, the displayed steering wheel icon is updated according to the steering wheel steering data at the current moment. This allows the displayed steering wheel icon to truly reflect the steering wheel steering state, making it convenient for the driver to promptly understand the actual steering state of the steering wheel. In addition, the method compares the steering wheel change angle between two moments with the preset angle threshold, and can update the steering wheel icon when the change angle is large, thereby reducing the icon update caused by slight vibrations of the vehicle, thereby avoiding misoperation caused by slight vibrations, so that the steering wheel icon can reflect the actual state of the steering wheel in real time, accurately and smoothly, ensuring that the driver can quickly take over the vehicle under various circumstances, thereby improving driving safety and user experience.

[0043] Figure 1 A flow chart of a method for displaying a steering wheel icon provided in an embodiment of the present application, which is suitable for displaying a steering wheel icon when running functions such as NOA, so as to reflect the actual steering state of the steering wheel in real time. The method for displaying a steering wheel icon provided in an embodiment of the present application can be executed by a display device for a steering wheel icon, which can be integrated into an electronic device by means of hardware and / or software, such as, integrated into an instrument panel controller or a HUD (Head Up Display) controller.

[0044] like Figure 1 As shown, the method for displaying a steering wheel icon provided in an embodiment of the present application includes the following steps:

[0045] S110: Acquire steering wheel steering data in real time.

[0046] In an embodiment of the present application, the steering wheel steering data can be collected in real time through a steering wheel steering sensor; and then the steering wheel steering sensor can send the steering wheel steering data to the instrument panel controller or the HUD controller through a CAN (Controller Area Network) bus.

[0047] The steering wheel steering data may include the steering wheel direction and the steering wheel angle. The steering wheel direction may be the direction actually controlled by the steering wheel, such as left, right or forward; the steering wheel angle may be the angle actually controlled by the steering wheel. Specifically, the real-time steering wheel steering data may be periodically acquired at a preset acquisition frequency; the preset acquisition frequency may be a data acquisition frequency set for standard working conditions or standard road conditions.

[0048] It should be noted that in the embodiment of the present application, each time the steering wheel steering data is collected, it can trigger the judgment of the subsequent steering wheel angle change to determine whether the steering wheel icon needs to be updated. Therefore, the update frequency of the steering wheel icon is synchronized with the collection frequency of the steering wheel steering data, ensuring that the icon can reflect the actual status of the steering wheel in real time.

[0049] S120, determining a steering wheel steering angle change between the previous moment and the current moment based on the steering wheel steering data at the current moment and the steering wheel steering data at the previous moment.

[0050] Specifically, after receiving the steering wheel data, the instrument panel controller or the HUD controller may parse the steering wheel data at the current moment, and extract the steering wheel direction and steering wheel angle at the current moment.

[0051] In the embodiment of the present application, before calculating the steering wheel change angle between the previous moment and the current moment, the steering wheel angle at the current moment may be preprocessed. For example, the steering wheel angle at the current moment may be converted and abnormal processing may be performed.

[0052] For angle conversion, specifically, when the steering wheel angle at the current moment exceeds the preset display range, the steering wheel angle at the current moment is converted to an equivalent value within the preset display range to obtain the angle value relative to the middle position of the steering wheel that needs to be displayed in the steering wheel icon.

[0053] The preset display range may be the angle range that can be displayed in the steering wheel icon, such as 0 to 360 degrees. For example, the steering wheel angle at the current moment is 540 degrees, which is converted to an equivalent value within 0 to 360 degrees, that is, 180 degrees. The angle conversion of the steering wheel angle at the current moment can facilitate the subsequent satisfaction of the 0 to 360 degree angle range that can be displayed in the icon, making it easier for the driver to understand the specific direction of the steering wheel relative to the middle position in real time.

[0054] For exception handling, specifically, when the current steering wheel angle is lost (i.e., the current steering wheel angle is not extracted), or the current steering wheel angle is abnormal (the value is not within the steering wheel angle range), the current steering wheel angle is updated with a default value (e.g., 0°). In addition, if the current steering wheel angle is detected to be an invalid value, i.e., the current steering wheel steering data is not collected according to the frequency, the current steering wheel angle can also be updated with a default value.

[0055] In the embodiment of the present application, after the steering wheel angle at the current moment is converted and the exception is handled, the steering wheel change angle between the two moments can be calculated based on the steering wheel angle at the current moment and the steering wheel angle at the previous moment. The steering wheel change angle can be understood as the angle change of the steering wheel between the two moments.

[0056] In this process, the steering wheel angles at the two moments involved in the calculation can both use the original steering wheel angles in the steering wheel steering data, or can both use the steering wheel angles after angle conversion and exception processing.

[0057] In a specific implementation, the steering wheel steering data includes a steering wheel direction and a steering wheel angle. Based on the steering wheel steering data at the current moment and the steering wheel steering data at the previous moment, determining the steering wheel angle change between the previous moment and the current moment includes the following steps:

[0058] Step 11, determine whether the steering wheel direction at the current moment is the same as that at the previous moment;

[0059] Step 12: If they are the same, determine the steering wheel change angle from the previous moment to the current moment based on the angle difference between the steering wheel angles at the current moment and the previous moment; otherwise, determine the steering wheel change angle from the previous moment to the current moment based on the angle sum between the steering wheel angles at the current moment and the previous moment.

[0060] Specifically, considering that there may be a situation where the steering wheel direction changes at two moments, different methods need to be used to calculate the steering wheel change angle between the two moments for the situation where the steering wheel direction changes and the situation where the steering wheel direction does not change.

[0061] Among them, in step 11, the steering wheel direction data of the previous moment can be read to determine whether the steering wheel direction of the current moment is the same as the steering wheel direction of the previous moment.

[0062] Furthermore, in step 12, if the steering wheel direction at the current moment is the same as the steering wheel direction at the previous moment, it means that the steering wheel has not returned to the middle position between the two moments. At this time, the steering wheel angle at the current moment can be subtracted from the steering wheel angle at the previous moment, and the absolute value of the difference result can be used as the steering wheel change angle between the two moments.

[0063] Exemplarily, if the steering wheel direction at the previous moment and the current moment is both left, or if the steering wheel direction at the previous moment and the current moment is both right, then the steering wheel change angle between the previous moment and the current moment = |steering wheel angle at the previous moment - steering wheel angle at the current moment|.

[0064] In addition, in step 12, if the steering wheel direction at the current moment is opposite to the steering wheel direction at the previous moment, it means that the steering wheel has returned to the middle position between the two moments. At this time, the travel of the steering wheel between the two moments can be divided into two parts, one part is the return of the steering wheel angle at the previous moment to the middle position, and the other part is the change from the middle position to the steering wheel angle at the current moment. Therefore, the steering wheel angle at the current moment can be summed with the steering wheel angle at the previous moment, and the sum value can be used as the steering wheel change angle between the two moments.

[0065] Exemplarily, the steering wheel was facing left at the previous moment, and the steering wheel is facing right at the current moment, or, the steering wheel was facing right at the previous moment, and the steering wheel is facing left at the current moment, then the steering wheel change angle between the previous moment and the current moment = the steering wheel angle at the previous moment + the steering wheel angle at the current moment.

[0066] Through the above steps 11 and 12, different calculation methods can be used to obtain the steering wheel change angle between the previous moment and the current moment for the situations where the steering wheel direction changes and does not change at two moments, thereby ensuring the accuracy of the steering wheel change angle and thus ensuring the reliability of the subsequent icon anti-shake processing combined with the preset angle threshold.

[0067] S130. In response to a steering wheel change angle being greater than a preset angle threshold, updating a displayed steering wheel icon based on the steering wheel steering data at a current moment.

[0068] Specifically, after obtaining the steering wheel angle change between the last moment and the current moment, it can be determined whether the steering wheel angle change is greater than a preset angle threshold, wherein the preset angle threshold can be a preset estimated value of the steering wheel angle change caused by a slight vibration of the vehicle, such as 2°.

[0069] Furthermore, if the steering wheel change angle is less than or equal to the preset angle threshold, it means that the steering wheel angle at the current moment is close to the steering wheel angle at the previous moment, and the change between the two moments may be caused by slight vibrations of the vehicle. At this time, there is no need to update the displayed steering wheel icon, and the steering wheel icon at the previous moment can continue to be displayed.

[0070] In addition, if the steering wheel change angle is greater than the preset angle threshold, it means that the steering wheel angle at the current moment is significantly different from the steering wheel angle at the previous moment, and the change between the two moments is caused by the steering wheel controller. At this time, the displayed steering wheel icon can be updated according to the steering wheel steering data at the current moment.

[0071] Exemplarily, the displayed steering wheel icon can be updated according to the current steering wheel angle and steering wheel direction, so that the updated steering wheel icon displays the steering wheel direction and steering wheel angle. In this process, the steering wheel icon can be updated using the current steering wheel angle that has been converted and handled abnormally.

[0072] The steering wheel icon may specifically include a steering wheel thumbnail and a marked direction, wherein the steering wheel thumbnail is used to describe the steering wheel angle, and the marked direction is used to describe the steering wheel direction. The steering wheel icon may be specifically displayed in the instrument panel, or in the vehicle interface, or on the front windshield through the HUD controller.

[0073] Figure 2 A forward steering wheel icon provided in an embodiment of the present application, Figure 3 A left turn steering wheel icon provided in an embodiment of the present application, Figure 4 A right turn steering wheel icon provided in an embodiment of the present application, such as Figure 2-Figure 4 As shown in the figure, the steering wheel icon includes a steering wheel thumbnail at the top and a marked direction at the bottom. Figure 2 The steering wheel icon is shown when the steering wheel angle is 0 and the steering wheel direction is positive; Figure 3 The steering wheel icon is shown when the steering wheel angle is greater than 0 and the steering wheel is facing left; Figure 4 The steering wheel icon is shown when the steering wheel angle is greater than 0 and the steering wheel is facing right.

[0074] In an embodiment of the present application, by comparing the changing angle of the steering wheel with a preset angle threshold, it is possible to implement anti-shake processing for the steering wheel icon, thereby avoiding updating the steering wheel icon due to slight vibrations of the vehicle, and ensuring that the steering wheel icon can accurately reflect the steering state of the steering wheel being actually controlled; moreover, it is also possible to reduce unnecessary icon updates, avoid frequent triggering of slight icon updates that may cause the driver to mistakenly believe that the vehicle has a malfunction, and make icon updates smoother and more natural, thereby enhancing the driver's visual experience through smooth and natural icon update animation effects.

[0075] Taking into account the different amplitudes of steering wheel vibration caused by external factors in different scenarios, the preset angle threshold can also be adaptively adjusted in combination with the vehicle's driving information, so as to achieve anti-shake processing for the steering wheel icon according to the adjusted preset angle threshold.

[0076] In a specific implementation, the method provided in the embodiment of the present application further includes the following steps:

[0077] Step 21: Obtaining vehicle driving information;

[0078] Step 22: determine whether the preset angle threshold satisfies a preset update condition based on the driving information; if so, update the preset angle threshold based on the driving information.

[0079] Among them, in step 21, the vehicle's driving information can describe the data related to the environment and driving of the vehicle during the driving process. For example, the vehicle's driving information can include information such as driving road conditions, driving weather, engine speed, suspension adjustment height, and driving conditions.

[0080] For example, the vehicle driving data and environmental perception data collected by various sensors can be obtained through the CAN bus, and information such as engine speed and suspension adjustment height can be extracted from the vehicle driving data. Based on the vehicle driving data and environmental perception data, the road condition, weather and operating condition can be identified to obtain information such as driving road condition, driving weather and driving operating condition.

[0081] Further, in step 22, it can be determined whether the preset angle threshold satisfies the preset update condition according to the driving information, that is, whether the preset angle threshold needs to be updated, and if so, the preset angle threshold can be updated according to the driving information. The preset update condition can be that the driving information satisfies a specific working condition, road condition or weather, etc.

[0082] For example, when the steering wheel vibration is small, the preset angle threshold may be appropriately lowered, and when the steering wheel vibration is large, the preset angle threshold may be appropriately increased.

[0083] Through the above steps 21 and 22, the preset angle threshold can be adaptively updated based on the driving information of the vehicle, and the threshold of the anti-shake processing can be dynamically adjusted in combination with the vibration conditions of the vehicle to ensure the accuracy and reliability of the anti-shake processing.

[0084] With respect to the above step 22, in one example, determining whether the preset angle threshold satisfies the preset update condition based on the driving information includes: determining whether the driving road condition in the driving information is the preset road condition, or whether the driving working condition in the driving information is the preset working condition, and if so, determining that the preset angle threshold satisfies the preset update condition;

[0085] Updating the preset angle threshold based on the driving information includes: obtaining a target threshold corresponding to the driving road condition or the driving working condition, and updating the preset angle threshold based on the target threshold.

[0086] The driving condition may be the type of road surface on which the vehicle is driving, such as urban roads, expressways, climbing slopes, pothole roads, ramps, etc. The driving condition may be the type of operating condition of the vehicle during driving, such as low-speed driving, emergency avoidance, emergency braking, etc.

[0087] Specifically, the driving road condition and the driving working condition in the driving information can be extracted to determine whether the driving road condition is a preset road condition, and to determine whether the driving working condition is a preset working condition.

[0088] Among them, the preset road condition can be a pre-set road condition that can cause frequent vibration of the steering wheel, such as climbing a slope, a bumpy road surface, etc.; or, the preset road condition can also be a road condition where the steering state of the steering wheel changes little, such as a highway. On a highway, the vehicle is in a straight-line driving state most of the time, and the steering wheel turning angle changes little.

[0089] The preset operating condition may be a pre-set operating condition that can cause frequent vibration of the steering wheel, such as emergency braking. Under emergency braking, the vehicle may produce greater vibrations and thus cause vibration of the steering wheel; or, the preset operating condition may also be an operating condition in which the steering state of the steering wheel is controlled to change little, such as low-speed driving. When the vehicle speed is lower than a certain threshold (for example, 30 km / h), it can be considered that the vehicle is driving at a low speed, and the steering wheel rotation angle changes little when driving at a low speed.

[0090] Specifically, if it is determined that the driving condition in the driving information is the preset condition, or the driving condition is the preset condition, it can be determined that the preset angle threshold satisfies the preset update condition, and then the target threshold corresponding to the driving condition that meets the preset condition can be read, or the target threshold corresponding to the driving condition that meets the preset condition can be read, and the preset angle threshold is updated to the target threshold. It should be noted that if the driving condition is equal to the preset condition, and the driving condition is equal to the preset condition, the target thresholds corresponding to the driving condition and the driving condition can be read at the same time, and the largest target threshold is taken to update the preset angle threshold.

[0091] The target threshold may be an angle threshold pre-stored for each preset road condition or preset working condition, which may be obtained through calibration. For example, for driving conditions such as climbing a slope or a bumpy road, considering that the vehicle body vibrates greatly under such conditions, which may cause the steering wheel to vibrate frequently, the corresponding target threshold may be 3°, so as to increase the preset angle threshold and update the steering wheel icon when the steering wheel angle change at two moments is greater than 3°.

[0092] For driving conditions such as highways, considering that the vehicle is in a straight-line driving state for a long time, the steering wheel rotation state changes little. Therefore, the corresponding target threshold can be 5° to increase the preset angle threshold and update the steering wheel icon when the steering wheel change angle at two moments is greater than 5°.

[0093] For driving conditions such as low-speed driving, considering that the steering wheel rotation state changes little when the vehicle is driving at low speed, the corresponding target threshold can be 3° to increase the preset angle threshold and update the steering wheel icon when the steering wheel change angle at two moments is greater than 3°.

[0094] For driving conditions such as emergency braking, taking into account that the vehicle may produce large vibrations during emergency braking and cause steering wheel vibrations, the corresponding target threshold can be 5° to increase the preset angle threshold and update the steering wheel icon when the steering wheel angle change at two moments is greater than 5°.

[0095] Through the above examples, it is possible to adaptively adjust the preset angle threshold based on driving road conditions and driving working conditions, thereby achieving the purpose of dynamically adjusting the anti-shake effect according to road conditions and working conditions, and further improving the accuracy of the steering wheel icon display.

[0096] In addition to adaptively adjusting the preset angle threshold based on the driving road condition and driving working condition, the preset angle threshold may also be adaptively adjusted based on the driving weather. With respect to the above step 22, in another example, judging whether the preset angle threshold satisfies the preset update condition based on the driving information includes: judging whether the driving weather in the driving information is the preset weather, and if so, determining that the preset angle threshold satisfies the preset update condition;

[0097] Updating the preset angle threshold based on driving information includes: obtaining a target threshold corresponding to driving weather, and updating the preset angle threshold based on the target threshold.

[0098] Specifically, the driving weather in the driving information can be extracted to determine whether the driving weather is the preset weather. The driving weather can be the weather type of the vehicle driving environment, such as rainy and snowy days, sunny days, foggy days, etc. The preset weather can be pre-set weather that can cause frequent vibration of the steering wheel, such as rainy and snowy days. In rainy and snowy weather, the vehicle is prone to slipping due to the slippery road surface, which in turn causes frequent vibration of the steering wheel.

[0099] In the above example, if it is determined that the driving weather in the driving information is the preset weather, it can be determined that the preset angle threshold meets the preset update condition, and then the target threshold corresponding to the driving weather can be read and the preset angle threshold can be updated to the target threshold.

[0100] The target threshold may be an angle threshold pre-stored for a preset weather condition, which may be obtained by calibration. For example, for driving weather conditions such as rainy and snowy days, considering that the vehicle body may cause steering wheel vibration due to slippage in such weather conditions, the corresponding target threshold may be 3°, so as to increase the preset angle threshold, and update the steering wheel icon when the steering wheel angle change at two moments is greater than 3°.

[0101] Through the above example, the preset angle threshold can be adaptively adjusted based on the driving weather, which can achieve the purpose of dynamically adjusting the anti-shake effect according to the weather and further improve the accuracy of the steering wheel icon display.

[0102] In addition to adaptively adjusting the preset angle threshold based on the driving road condition, driving condition or driving weather, the preset angle threshold may also be adaptively adjusted based on the engine speed. With respect to the above step 22, in another example, judging whether the preset angle threshold satisfies the preset update condition based on the driving information includes: judging whether the engine speed in the driving information is greater than the preset speed, and if so, determining that the preset angle threshold satisfies the preset update condition;

[0103] Updating the preset angle threshold based on the driving information includes: updating the preset angle threshold based on a difference between an engine speed and a preset speed.

[0104] Among them, considering that the operation of the engine may also cause the steering wheel to vibrate, especially when the engine speed is high, the steering wheel may vibrate frequently. Therefore, the engine speed can be extracted from the driving information to determine whether the engine speed is greater than the preset speed.

[0105] Specifically, the preset speed may be a preset critical speed that can cause the steering wheel to vibrate frequently during engine operation. If the engine speed is greater than the preset speed, it can be determined that the preset angle threshold satisfies the preset update condition, and the preset angle threshold can be updated according to the engine speed.

[0106] For example, the difference between the engine speed and the preset speed can be calculated to measure the steering wheel vibration caused by the engine operation through the difference. The larger the difference, the greater the steering wheel vibration, and the preset angle threshold is updated based on the difference. For example, the preset angle threshold is increased. The larger the difference, the greater the increase in the preset angle threshold.

[0107] Through the above example, it is possible to adaptively adjust the preset angle threshold based on the engine operating conditions, taking into account the impact of engine operation on the steering wheel, so as to achieve the purpose of dynamically adjusting the anti-shake effect according to the engine speed in real time, and further improve the accuracy of the steering wheel icon display.

[0108] In addition to adaptively adjusting the preset angle threshold based on the driving road condition, driving condition, driving weather or engine speed, the preset angle threshold may also be adaptively adjusted based on the suspension data. With respect to the above step 22, in another example, judging whether the preset angle threshold satisfies the preset update condition based on the driving information includes: judging whether the suspension adjustment height in the driving information is greater than the preset height, and whether the suspension adjustment frequency is greater than the preset adjustment frequency, and if so, determining that the preset angle threshold satisfies the preset update condition;

[0109] Updating the preset angle threshold based on the driving information includes: updating the preset angle threshold based on a difference between the suspension adjustment height and the preset height.

[0110] Among them, considering that suspension adjustment may also cause steering wheel vibration, especially when the suspension adjustment height is large and the adjustment is frequent, it may cause frequent steering wheel vibration. Therefore, the suspension adjustment height and suspension adjustment frequency can be extracted from the driving information to determine whether the suspension adjustment height is greater than the preset height and whether the suspension adjustment frequency is greater than the preset adjustment frequency.

[0111] Furthermore, if the suspension adjustment height is greater than the preset height, and the suspension adjustment frequency is greater than the preset adjustment frequency, it means that the suspension adjustment amplitude and frequency of the vehicle are large at this time, which will cause a large vibration of the vehicle body, and then cause the steering wheel to vibrate. Therefore, it can be determined that the preset angle threshold meets the preset update condition, and the preset angle threshold can be updated by the suspension adjustment height.

[0112] For example, the difference between the suspension adjustment height and the preset height can be calculated to measure the steering wheel vibration caused by the suspension adjustment. The larger the difference, the greater the steering wheel vibration. The preset angle threshold is then updated based on the difference. For example, the preset angle threshold is increased. The larger the difference, the greater the increase in the preset angle threshold.

[0113] Through the above example, it is possible to adaptively adjust the preset angle threshold based on the suspension adjustment situation, take into account the impact of the suspension adjustment on the steering wheel, and achieve the purpose of dynamically adjusting the anti-shake effect according to the suspension adjustment height in real time, thereby further improving the accuracy of the steering wheel icon display.

[0114] In the embodiment of the present application, after the preset angle threshold is adjusted, the subsequently collected steering wheel steering data, i.e., the steering wheel steering data at the next moment, can be subjected to anti-shake processing based on the updated preset angle threshold. Of course, when changes in working conditions, road conditions, weather, engine speed, or suspension adjustment are detected again, the preset angle threshold can also be adaptively adjusted again.

[0115] The method provided in the embodiment of the present application can not only adaptively adjust the preset angle threshold, but also dynamically adjust the collection frequency of the steering wheel steering data to achieve the purpose of adjusting the icon update frequency.

[0116] In another specific implementation, the method provided in the embodiment of the present application further includes:

[0117] Based on the driving road condition or driving working condition in the driving information, the collection frequency of the steering wheel steering data is updated to obtain the steering wheel steering data in real time according to the updated collection frequency.

[0118] Specifically, the driving road condition or driving working condition in the driving information may be extracted to determine whether the driving road condition is a road condition updated at a preset frequency, or whether the driving working condition is a working condition updated at a preset frequency.

[0119] The frequently updated road condition may be a preset road condition that requires a change in icon update frequency, such as an urban road or a ramp. The frequently updated working condition may be a preset working condition that requires a change in icon update frequency, such as emergency avoidance.

[0120] Specifically, if the driving road condition is a frequently updated road condition, or the driving operating condition is a frequently updated operating condition, the collection frequency of the steering wheel steering data may be updated according to the frequently updated road condition or the frequently updated operating condition.

[0121] For example, for urban roads, vehicles frequently change lanes and turn on urban roads, and the steering wheel icon needs to be updated quickly. Therefore, the frequency of collecting steering wheel steering data can be increased to increase the icon update frequency. For ramps, the steering wheel turning angle of the vehicle changes greatly when entering and exiting the ramp, and the steering wheel icon needs to be updated quickly. Therefore, the frequency of collecting steering wheel steering data can be increased to increase the icon update frequency. For emergency avoidance, the steering wheel turning angle of the vehicle changes greatly and at a fast speed during emergency avoidance, and the steering wheel icon needs to be updated quickly to ensure that the icon can reflect the actual status of the steering wheel in real time and help the driver respond quickly. Therefore, the frequency of collecting steering wheel steering data can be increased to increase the icon update frequency.

[0122] It should be noted that after updating the collection frequency of the steering wheel steering data, for subsequent collection of the steering wheel steering data, the steering wheel steering data can be periodically acquired at the updated collection frequency. Of course, when a change in the working condition or road condition is detected again, the collection frequency can be adaptively adjusted again.

[0123] Through the above implementation, it is possible to adaptively adjust the collection frequency based on driving conditions or driving working conditions, thereby adjusting the icon update frequency. Under certain specific road conditions or working conditions, high-frequency data collection can be used to ensure that the icon can reflect the actual status of the steering wheel in real time, ensuring that the driver can quickly take over the vehicle in various situations.

[0124] The method for displaying a steering wheel icon provided in an embodiment of the present application obtains steering wheel steering data in real time, determines the steering wheel change angle between the previous moment and the current moment according to the steering wheel steering data at the current moment and the steering wheel steering data at the previous moment, and when the steering wheel change angle is greater than a preset angle threshold, updates the displayed steering wheel icon according to the steering wheel steering data at the current moment, so that the displayed steering wheel icon can truly reflect the steering state of the steering wheel, making it convenient for the driver to promptly understand the actual steering state of the steering wheel. In addition, the method compares the steering wheel change angle between two moments with the preset angle threshold, and can update the steering wheel icon when the change angle is large, thereby reducing icon updates caused by slight vibrations of the vehicle, thereby avoiding misoperation caused by slight vibrations, so that the steering wheel icon can reflect the actual state of the steering wheel in real time, ensuring that the driver can quickly take over the vehicle under various circumstances, thereby improving driving safety and user experience.

[0125] It should be noted that the method of the embodiment of the present application can be performed by a single device, such as a computer or server. The method of this embodiment can also be applied to a distributed scenario and completed by multiple devices cooperating with each other. In the case of such a distributed scenario, one of the multiple devices can only perform one or more steps in the method of the embodiment of the present application, and the multiple devices will interact with each other to complete the described method.

[0126] It should be noted that the above describes some embodiments of the present application. Other embodiments are within the scope of the appended claims. In some cases, the actions or steps recorded in the claims can be performed in an order different from that in the above embodiments and still achieve the desired results. In addition, the processes depicted in the accompanying drawings do not necessarily require the specific order or continuous order shown to achieve the desired results.
