[0038] Example 1

[0039] Figure 1 This is a flowchart illustrating a steering wheel heating method according to Embodiment 1 of the present invention. This embodiment is applicable to situations such as steering wheel heating control. The method can be executed by the steering wheel heating device provided by the present invention. This device can be implemented using software and / or hardware. In a specific embodiment, the device can be integrated into an electronic device. The following embodiments will illustrate this using the integration of the device into an electronic device as an example. (Refer to...) Figure 1 The method specifically includes the following steps:

[0040] S101. Obtain the temperature information of the steering wheel based on the target time.

[0041] The target time can be understood as the time for collecting steering wheel temperature information, and the steering wheel temperature information can be understood as the temperature value of the steering wheel.

[0042] Specifically, obtaining steering wheel temperature information based on a target time can be understood as acquiring the steering wheel temperature value at the target time. The steering wheel temperature value can be determined by a temperature acquisition device or temperature sensor placed near the steering wheel. For example, assuming the target time is X, and a temperature sensor is placed on one side of the steering wheel, then when the current time reaches X, the temperature value of the steering wheel is acquired through the temperature sensor.

[0043] The advantage of this setup is that a temperature sensor can be used to collect the real-time temperature value of the steering wheel, so as to determine in real time whether the temperature of the steering wheel exceeds the temperature threshold.

[0044] S102. Determine the first temperature diagnosis result of the steering wheel based on the first determination method, the target temperature threshold, and the temperature information.

[0045] The first determination method can be understood as using the BCM to determine whether the temperature of the steering wheel exceeds the target temperature threshold; the target temperature threshold can be understood as the highest temperature value of the steering wheel that will not burn the driver; the first temperature diagnosis result can be understood as the temperature assessment result of the steering wheel, including the steering wheel temperature not exceeding the target temperature threshold, the steering wheel temperature equal to the target temperature threshold, and the steering wheel temperature exceeding the target temperature threshold. The steering wheel temperature not exceeding the target temperature threshold can be understood as the steering wheel temperature being normal, and the steering wheel temperature being equal to the target temperature threshold and the steering wheel temperature exceeding the target temperature threshold can be understood as the steering wheel temperature being abnormal.

[0046] Specifically, when the steering wheel temperature is below the target temperature threshold, the steering wheel temperature will not harm the driver, and the steering wheel temperature is considered normal. When the steering wheel temperature is above the target temperature threshold, the steering wheel temperature is too high and may burn the driver, and the steering wheel temperature is considered abnormal. The target temperature threshold is the maximum steering wheel temperature value set according to industry standards and the steering wheel heating control logic. It can be adjusted according to industry standards, the steering wheel heating control logic, and heating requirements; this embodiment of the invention does not limit this adjustment.

[0047] The determination of the first temperature diagnosis result of the steering wheel based on the first determination method, the target temperature threshold, and the temperature information can be understood as judging the temperature information of the steering wheel based on the BCM, determining the relationship between the temperature information of the steering wheel and the target temperature threshold, and determining the first temperature diagnosis result of the steering wheel based on the relationship between the temperature information of the steering wheel and the target temperature threshold. When the temperature information of the steering wheel is less than the target temperature threshold, the first temperature diagnosis result is determined to be that the temperature of the steering wheel is normal. When the temperature information of the steering wheel is not less than the target temperature threshold, the first temperature diagnosis result is determined to be that the temperature of the steering wheel is abnormal, that is, the temperature of the steering wheel is too high.

[0048] S103. Determine the second temperature diagnosis result of the steering wheel based on the second determination method, the target temperature threshold, and the temperature information.

[0049] The second determination method can be understood as using HOD (Hardware of Determining) to determine whether the steering wheel temperature exceeds the target temperature threshold. Similar to the first temperature diagnosis result, the second temperature diagnosis result can be understood as the steering wheel temperature assessment result, including steering wheel temperature not exceeding the target temperature threshold, steering wheel temperature equal to the target temperature threshold, and steering wheel temperature exceeding the target temperature threshold. A steering wheel temperature not exceeding the target temperature threshold can be understood as a normal steering wheel temperature, while a steering wheel temperature equal to or exceeding the target temperature threshold can be understood as an abnormal steering wheel temperature. Specifically, when the steering wheel temperature is less than the target temperature threshold, the steering wheel temperature will not harm the driver, and the steering wheel temperature is considered normal. When the steering wheel temperature is not less than the target temperature threshold, the steering wheel temperature is too high and may burn the driver, and the steering wheel temperature is considered abnormal.

[0050] The second temperature diagnostic result of the steering wheel, determined based on the second determination method, the target temperature threshold, and the temperature information, can be understood as judging the temperature information of the steering wheel based on the HOD (Heterostatic Determination) method, determining the relationship between the temperature information of the steering wheel and the target temperature threshold, and determining the second temperature diagnostic result of the steering wheel based on the relationship between the temperature information of the steering wheel and the target temperature threshold. When the temperature information of the steering wheel is less than the target temperature threshold, the second temperature diagnostic result is determined to be that the temperature of the steering wheel is normal. When the temperature information of the steering wheel is not less than the target temperature threshold, the second temperature diagnostic result is determined to be that the temperature of the steering wheel is abnormal, that is, the temperature of the steering wheel is too high.

[0051] S104. Determine the heating method of the steering wheel based on the first temperature diagnosis result and the second temperature diagnosis result.

[0052] The heating method of the steering wheel can be understood as the attribute information of the heating operation of the steering wheel, including starting the heating operation, continuing the heating operation, and pausing the heating operation, etc. This embodiment does not limit this.

[0053] Specifically, the first temperature diagnostic result and the second temperature diagnostic result are two temperature assessment results of the steering wheel temperature. If both assessment results indicate that the steering wheel temperature does not exceed the target temperature threshold, it proves that the steering wheel temperature is not high, and the steering wheel can continue to be heated, and the steering wheel heating method is determined to be heating. If either assessment result indicates that the steering wheel temperature exceeds the target temperature threshold, it is considered that the steering wheel temperature may be too high, and there is a possibility of burning the driver. The steering wheel heating needs to be stopped, and the steering wheel heating method is determined to be no heating.

[0054] The advantage of this setup is that it adds a safety mechanism (using HOD to determine whether the temperature information is higher than or equal to the target temperature threshold). By using two methods to detect the temperature of the steering wheel and determining the heating method of the steering wheel based on the two detection results, the accuracy of steering wheel temperature diagnosis can be improved, the probability of temperature misjudgment can be reduced, the safety of the steering wheel heating function can be increased, and the personal safety of the driver can be protected.

[0055] S105, Control the steering wheel to operate based on the heating method to heat the steering wheel.

[0056] The vehicle in this embodiment is equipped with a heating device for heating the steering wheel.

[0057] Specifically, controlling the steering wheel to operate based on the heating mode can be understood as heating the steering wheel according to the heating mode determined in step S104. For example, when the heating mode is heating, the heating device is used to heat the steering wheel; when the heating mode is not heating, the operation of the heating device is stopped, and the steering wheel is not heated temporarily.

[0058] The advantage of this design is that it keeps the temperature of the steering wheel within a reasonable range, allowing the driver to drive the vehicle warmly without burning them.

[0059] The technical solution of this embodiment obtains steering wheel temperature information based on a target time; determines a first temperature diagnosis result of the steering wheel based on a first determination method, a target temperature threshold, and the temperature information; determines a second temperature diagnosis result of the steering wheel based on a second determination method, a target temperature threshold, and the temperature information; determines a heating method for the steering wheel based on the first and second temperature diagnosis results; and controls the steering wheel to operate according to the heating method to heat the steering wheel. This invention uses two methods to detect the temperature of the steering wheel and determines the heating method based on the two detection results. This allows for accurate detection of the steering wheel temperature information, improves the accuracy of steering wheel temperature diagnosis, reduces the possibility of overheating the steering wheel, and improves vehicle safety and the user experience. It also solves the problem that a BCM (Body Control Module) is not a professional temperature-judging instrument; if the BCM misjudges, it may cause the steering wheel to continuously heat up, resulting in excessively high steering wheel temperatures and affecting driver safety.

[0060] Example 2

[0061] Figure 2 This is a schematic flowchart illustrating a steering wheel heating method according to Embodiment 2 of the present invention. This embodiment is applicable to situations such as steering wheel heating control. The method can be executed by the steering wheel heating device provided by the present invention. This device can be implemented using software and / or hardware. In a specific embodiment, the device can be integrated into an electronic device. The following embodiments will be described using the integration of this device into an electronic device as an example. (Refer to...) Figure 2 The method specifically includes the following steps:

[0062] S201. Determine the target temperature threshold.

[0063] The target temperature threshold can be understood as the highest temperature of the steering wheel that will not burn the driver. Specifically, when the temperature of the steering wheel is below the target temperature threshold, heating the steering wheel provides a warm driving environment for the driver. Once the temperature of the steering wheel exceeds the target temperature threshold, it will cause injury to the driver.

[0064] In one embodiment, step S201 may specifically include: determining the maximum temperature threshold of the steering wheel; and determining a target temperature threshold based on the maximum temperature threshold and a preset temperature threshold.

[0065] The maximum temperature threshold can be understood as the highest temperature at which the steering wheel can be heated according to industry standards, including 60 degrees Celsius, 65 degrees Celsius, 70 degrees Celsius, etc. The maximum temperature threshold can be determined according to the vehicle model and industry standards. The target temperature threshold is the difference between the maximum temperature threshold and the preset temperature threshold. The preset temperature threshold is the basis for determining the target temperature threshold, including 3 degrees Celsius, 5 degrees Celsius, 7 degrees Celsius, 10 degrees Celsius, etc. This embodiment does not limit this.

[0066] For example, assuming the maximum temperature threshold is 70 degrees Celsius and the preset temperature threshold is 5 degrees Celsius, the target temperature threshold is 65 degrees Celsius.

[0067] The advantage of this setting is that it determines the target temperature threshold based on both the maximum and preset temperature thresholds. This protects driver safety and avoids relying solely on the maximum temperature threshold to determine whether to heat the steering wheel. If the steering wheel temperature is not collected in a timely manner, it can easily exceed the maximum temperature threshold, potentially causing injury to the driver. By using a target temperature threshold below the maximum temperature threshold as the criterion for heating, it ensures that the steering wheel temperature does not exceed the maximum temperature threshold, improving vehicle safety and protecting the driver.

[0068] S202. Obtain the temperature information of the steering wheel based on the target time.

[0069] Specifically, obtaining steering wheel temperature information based on a target time can be understood as obtaining the steering wheel temperature value at the target time. The steering wheel temperature value can be determined by a temperature acquisition device or temperature sensor placed near the steering wheel.

[0070] In one embodiment, step S202 may specifically include: determining whether the current time is the target time; if the current time is the target time, then acquiring temperature information based on the temperature acquisition device.

[0071] Here, the current time can be understood as the constantly changing real-time time. Specifically, if the current time is the target time, then it is determined that the current time meets the temperature acquisition conditions, and the temperature of the steering wheel will be collected based on the temperature acquisition device set near the steering wheel.

[0072] S203. Determine the first temperature diagnosis result of the steering wheel based on the first determination method, the target temperature threshold, and the temperature information.

[0073] Specifically, determining the first temperature diagnostic result of the steering wheel based on the first determination method, the target temperature threshold, and the temperature information can be understood as determining the first temperature diagnostic result of the steering wheel based on the BCM, the target temperature threshold, and the temperature information.

[0074] In one embodiment, step S203 may specifically include: determining whether the temperature information is less than a target temperature threshold based on the body control module (BCM); if the temperature information is less than the target temperature threshold, then determining the first temperature diagnosis result as normal temperature; if the temperature information is greater than or equal to the target temperature threshold, then determining the first temperature diagnosis result as abnormal temperature.

[0075] For example, assuming the target temperature threshold is 65 degrees Celsius, the steering wheel temperature collected by the temperature sensor is judged based on the BCM. If the steering wheel temperature is less than 65 degrees Celsius, it is considered that the steering wheel is not overheating, and the first temperature diagnosis result is determined to be normal. If the steering wheel temperature is greater than or equal to 65 degrees Celsius, it is considered that the steering wheel is overheating, and the first temperature diagnosis result is determined to be abnormal.

[0076] S204. Determine the second temperature diagnostic result of the steering wheel based on the second determination method, the target temperature threshold, and the temperature information.

[0077] Specifically, the second temperature diagnostic result of the steering wheel determined based on the second determination method, the target temperature threshold, and the temperature information can be understood as the second temperature diagnostic result of the steering wheel determined based on HOD, the target temperature threshold, and the temperature information.

[0078] In one embodiment, step S204 may specifically include: determining whether the temperature information is less than a target temperature threshold based on the off-hand detection HOD; if the temperature information is less than the target temperature threshold, then determining the second temperature diagnosis result as normal temperature; if the temperature information is greater than or equal to the target temperature threshold, then determining the second temperature diagnosis result as abnormal temperature.

[0079] For example, assuming the target temperature threshold is 65 degrees Celsius, the steering wheel temperature collected by the temperature sensor is judged based on HOD. If the steering wheel temperature is less than 65 degrees Celsius, it is considered that the steering wheel is not overheating, and the second temperature diagnosis result is determined to be normal. If the steering wheel temperature is greater than or equal to 65 degrees Celsius, it is considered that the steering wheel is overheating, and the second temperature diagnosis result is determined to be abnormal.

[0080] S205. Determine the heating method of the steering wheel based on the first temperature diagnosis result and the second temperature diagnosis result.

[0081] Specifically, determining the steering wheel heating method based on the first and second temperature diagnostic results can be understood as determining whether to heat the steering wheel based on two diagnostic results.

[0082] In one embodiment, step S205 may specifically include: determining whether the first temperature diagnostic result and the second temperature diagnostic result are normal temperatures; if both the first temperature diagnostic result and the second temperature diagnostic result are normal temperatures, then determining that the steering wheel heating mode is heating; if the first temperature diagnostic result is abnormal temperatures and / or the second temperature diagnostic result is abnormal temperatures, then determining that the steering wheel heating mode is not heating.

[0083] Specifically, if both the first and second temperature diagnostic results indicate that the temperature of the steering wheel is normal, it proves that both assessment results indicate that the temperature of the steering wheel has not exceeded the target temperature threshold and the temperature of the steering wheel is not high. The steering wheel can continue to be heated, and the heating method of the steering wheel is determined to be heating. If the first temperature diagnostic result indicates that the temperature is abnormal and / or the second temperature diagnostic result indicates that the temperature is abnormal, it proves that at least one assessment result indicates that the temperature of the steering wheel exceeds the target temperature threshold. It is believed that the temperature of the steering wheel may burn the driver, and the heating of the steering wheel needs to be stopped. The heating method of the steering wheel is determined to be no heating.

[0084] The advantage of this setup is that it adds a safety mechanism by using two methods to detect the temperature of the steering wheel and determining the heating method based on the two detection results. This improves the accuracy of steering wheel temperature diagnosis, reduces the probability of temperature misjudgment, increases the safety of the steering wheel heating function, and protects the personal safety of the driver.

[0085] S206, Control the steering wheel to operate based on the heating method to heat the steering wheel.

[0086] Specifically, controlling the steering wheel to operate based on the heating mode can be understood as heating the steering wheel according to the heating mode determined in step S205. For example, when the heating mode is heating, the heating device is used to heat the steering wheel; when the heating mode is not heating, the operation of the heating device is stopped, and the steering wheel is not heated temporarily.

[0087] Optionally, when both the first and second temperature diagnostic results are normal, the method further includes: determining the temperature difference between the temperature information and the target temperature threshold based on the body control module (BCM); determining whether the temperature difference is less than a preset temperature difference threshold; and if the temperature difference is less than the preset temperature difference threshold, determining that the steering wheel heating mode is not heated.

[0088] The preset temperature difference threshold can be understood as a temperature value for a heating protection mechanism, including 0.1 degrees Celsius, 0.3 degrees Celsius, 0.5 degrees Celsius, 1 degree Celsius, etc. The preset temperature difference threshold can be set and adjusted according to the performance of the heating device and the frequency of collecting steering wheel temperature information. If the performance of the heating device is high and / or the frequency of collecting steering wheel temperature information is low, a preset temperature difference threshold with a larger temperature value is determined. If the performance of the heating device is low and / or the frequency of collecting steering wheel temperature information is high, a preset temperature difference threshold with a smaller temperature value is set. This embodiment of the invention does not limit this.

[0089] Specifically, when both the first and second temperature diagnostic results are normal, a second assessment of the temperature information can be performed to determine whether the steering wheel needs to be heated. If the temperature difference is less than the preset temperature difference threshold, it proves that the temperature of the steering wheel is close to the target temperature threshold. If the steering wheel is heated further, the temperature of the steering wheel may exceed the target temperature threshold, affecting the personal safety of the driver. Therefore, the heating method of the steering wheel can be determined to be no heating, thereby reducing the possibility of the driver being burned by the overheated steering wheel.

[0090] The advantage of this setup is that it establishes a dual-layer protection strategy, protecting the personal safety of the driver, improving vehicle safety, and enhancing the driver's driving experience.

[0091] S207. Update the target time based on the preset duration.

[0092] During vehicle operation, the steering wheel heating control process is continuous, therefore, the steering wheel temperature information is acquired periodically. The preset duration can be understood as the time difference between two acquisitions of steering wheel temperature information. The preset duration is generally between 5 and 50 milliseconds, and the specific value is related to the steering wheel heating logic; this embodiment does not limit this.

[0093] When controlling the steering wheel to operate based on the heating mode to heat the steering wheel, or after obtaining the temperature information of the steering wheel based on the target time, the method further includes: updating the target time based on a preset duration, and performing the step of obtaining the temperature information of the steering wheel based on the target time.

[0094] Specifically, updating the target time and determining whether to heat the steering wheel are two separate logics, which do not conflict. The target time can be updated based on a preset duration when the steering wheel is controlled to operate based on the heating mode to heat the steering wheel, or it can be updated based on a preset duration after obtaining the temperature information of the steering wheel based on the target time. This embodiment does not limit this.

[0095] For example, suppose that when the steering wheel is controlled to operate in a heating mode to heat the steering wheel, the target time is updated based on a preset duration. Suppose the target time is A and the preset duration is B. Then, when the steering wheel is controlled to operate in a heating mode to heat the steering wheel, the target time is determined to be A+B, and the step of obtaining the temperature information of the steering wheel based on the target time (the target time at this time is A+B) is executed.

[0096] The advantage of this setup is that it can continuously monitor the temperature of the steering wheel, determine the heating mode in real time, and dynamically adjust the heating mode based on the steering wheel's temperature information.

[0097] The technical solution of this embodiment involves determining a target temperature threshold; acquiring steering wheel temperature information based on a target time; determining a first temperature diagnostic result for the steering wheel based on a first determination method, the target temperature threshold, and the temperature information; determining a second temperature diagnostic result for the steering wheel based on a second determination method, the target temperature threshold, and the temperature information; determining a heating method for the steering wheel based on the first and second temperature diagnostic results; controlling the steering wheel to operate according to the heating method to heat the steering wheel; updating the target time based on a preset duration; and executing the steps of acquiring steering wheel temperature information based on the target time. This invention uses two methods to detect the steering wheel temperature based on a target temperature threshold and determines the steering wheel heating method based on the two detection results. This allows for accurate detection of steering wheel temperature information, improving the diagnostic accuracy of steering wheel temperature, reducing the possibility of overheating the steering wheel, and improving vehicle safety and user experience. Furthermore, this embodiment updates the target time in real time and repeatedly detects the steering wheel temperature, enhancing vehicle safety and ensuring driver safety. It also addresses the problem that a BCM (Body Control Module) is not a professional temperature-judging instrument, and misjudgment by the BCM could lead to continuous steering wheel heating, causing excessively high steering wheel temperatures and affecting driver safety.
