[0066] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0067] According to the background description of this application, vehicle steering wheels have gradually evolved from controlling the direction of vehicle travel to having more control functions, such as multimedia mode switching, voice prompts, and emergency condition alarms.

[0068] In existing technologies, pressure sensors, acceleration sensors, and other sensors are generally integrated into the steering wheel. Once the sensors detect the driver operating the steering wheel, they will trigger the corresponding control command to control the corresponding functions of the vehicle.

[0069] The types of driver operations that can be detected by steering wheel tapping sensors in the current technology are limited. They can only realize the control of simple vehicle functions and are prone to accidental touches, and cannot accurately identify the user's true intentions.

[0070] Therefore, to address the aforementioned problems, this application proposes a vehicle control method, a vehicle, a computer-readable storage medium, and a computer program product based on a HOD (Hands Off Detection) system, such as... Figure 1 As shown, the HOD system in this application includes an HOD sensor acquisition unit and an HOD sensor signal processing unit. The HOD sensor acquisition unit can be arranged on the rim of the steering wheel. When the user taps the corresponding area of ​​the steering wheel, the HOD sensor acquisition unit acquires the tapping data and transmits the tapping data to the HOD sensor signal processing unit. The user's tapping intention is then identified based on the processed data.

[0071] The steering wheel structure in this application can be as follows: Figures 2-1 to 2-3 As shown:

[0072] (1) The HOD system acquisition unit is located on the steering wheel body 100, in a safe area that the user can easily touch; 100 is divided into four areas A001 to A004 on the side facing the driver, A001: area 1, A002: area 2, A003: area 3 and A004: area 4, and is divided into A005: area 5 on the side facing away from the driver;

[0073] (2) The HOD processing unit is integrated in the steering wheel switch 200 and shares the steering wheel ECU with other steering wheel functional units;

[0074] Based on this, such as Figure 1 As shown, the impact signal collected by the HOD system acquisition unit is output by the steering wheel ECU and transmitted to the vehicle functional system via the vehicle CAN bus. The vehicle functional system may include, but is not limited to, the central control multimedia system, the instrument cluster system, the window control system, the Bluetooth system, etc.

[0075] In this embodiment, the HOD system acquisition unit can use a capacitive sensor to detect the user's tapping operation on the aforementioned area of ​​the steering wheel.

[0076] In this application, the aforementioned HOD system is integrated into the steering wheel switch circuit board, eliminating the need for external attachment to other parts of the steering wheel. This reduces the space occupied inside the steering wheel, and the multiple detection areas can be mainly distributed in the steering wheel rim area, providing wide and flexible coverage. This allows users to conveniently control the vehicle's multiple functions without taking their hands off the steering wheel while enjoying a safe driving environment.

[0077] In addition to placing the HOD system on the steering wheel, this embodiment can also place the HOD system in other areas of the vehicle, such as the seat handle, seat back, or interior of the vehicle, so that people in the vehicle (passengers or driver) can control the vehicle by tapping the corresponding area. This embodiment does not make specific limitations on this.

[0078] Based on this, the vehicle control method in the embodiments of this application can be applied to vehicles, such as gasoline vehicles, plug-in hybrid electric vehicles, or new energy vehicles, etc. This application does not specifically limit this. The vehicle control method in the embodiments of this application, such as... Figure 3 As shown, it can specifically include the following steps:

[0079] S10, acquire control signals;

[0080] In this embodiment, the vehicle can acquire control signals through the HOD system acquisition unit.

[0081] In one specific embodiment, S10 may include:

[0082] The system acquires control signals triggered by the steering wheel of the target vehicle to determine, based on the control signals, a slapping event applied to the steering wheel.

[0083] In this embodiment, the control signal can be a control signal applied by the user to the steering wheel of the target vehicle.

[0084] As described above, a capacitive sensor can be installed in at least one of the A001 to A005 areas of the steering wheel, so that the vehicle can control the capacitive sensor to collect the control information applied by the user to the steering wheel of the target vehicle. For example, the target area can be tapped at a certain frequency and number of times to generate a corresponding control signal. In this embodiment, the control signal can be a capacitance change signal (usually manifested as a change in voltage or current).

[0085] Understandably, the principle by which capacitive sensors identify the contact area between the steering wheel and the hand is mainly based on changes in capacitance. For example, when the driver's hand touches the steering wheel, a capacitance is formed between the human body and the steering wheel. The size of the capacitance is proportional to the contact area; the larger the contact area, the larger the capacitance value. Capacitive sensors can detect this change in capacitance, thereby determining the contact state between the driver's hand and the steering wheel.

[0086] Specifically, a capacitive sensor typically consists of multiple electrodes distributed on or inside the steering wheel. When the driver's hand touches the steering wheel, a capacitance is formed between the human body and these electrodes. By measuring the change in capacitance on these electrodes, the capacitive sensor can determine whether the driver's hand is on the steering wheel, and the location and area of ​​contact. The system analyzes this data to determine whether the driver is gripping the steering wheel correctly and whether it is safe to release their hands in autonomous driving mode.

[0087] In addition, according to the above description, in this embodiment, besides setting the HOD system on the steering wheel, the HOD system can also be set in other areas of the vehicle, such as the seat handle, seat back, or interior of the vehicle body, without any specific limitation.

[0088] The following description uses the HOD system set on the steering wheel as an example to illustrate each embodiment.

[0089] S20, determine the striking event based on the control signal;

[0090] In this embodiment, the vehicle can process the control signal to obtain the slapping event.

[0091] In this embodiment, the tapping event can be based on a tapping event applied by the user to the steering wheel. For example, after receiving a control signal triggered by the steering wheel, the vehicle can process the control signal to identify the tapping event applied by the user. The vehicle's processing of the control signal can involve statistical analysis of the received control signal to extract signal features to identify the tapping event triggered by the user. This will be described in detail in subsequent embodiments and will not be repeated here.

[0092] It should be noted that, in this embodiment, the tapping event can be a functional event unrelated to functional safety, such as switching multimedia modes, adjusting playback volume, answering a phone call, etc., or a functional event that transmits information to other users inside or outside the vehicle, such as voice reminders like "Please fasten your seatbelt" or "Do not stick your hands out of the window," or a low-volume horn reminder to pedestrians and vehicles nearby. This embodiment does not limit the type of tapping event, allowing users to control the vehicle by tapping the steering wheel.

[0093] S30, control the target vehicle according to the control command corresponding to the striking event.

[0094] In this embodiment, after processing the control signal and obtaining the tapping event applied by the user on the steering wheel, the vehicle can determine the control command corresponding to the tapping event and control the vehicle according to the control command.

[0095] For example, such as Figure 1 As shown, after the vehicle uses sensors to collect control signals and processes them, the signals are output by the steering wheel ECU and transmitted to the vehicle's functional systems via the vehicle's CAN bus. These vehicle functional systems include, for example, the central control multimedia system, the instrument cluster system, the window control system, and the Bluetooth system.

[0096] As can be seen, in this embodiment, the vehicle can collect control signals applied by the user to the steering wheel of the target vehicle. After receiving the direction-triggered control signal, the vehicle can process the control signal to identify the tapping event applied by the user to the steering wheel and obtain the tapping feature corresponding to the tapping event. After processing the control signal and obtaining the tapping event applied by the user to the steering wheel and the tapping feature of the tapping event, the vehicle can determine the control command corresponding to the tapping feature and control the vehicle according to the control command. Therefore, in this application, the driver can directly apply the corresponding tapping event to the steering wheel to achieve more complex and higher-level functional control of the vehicle, and the driver does not need to take their hands off the steering wheel during driving, thus ensuring safe driving.

[0097] In one embodiment, the control signal includes multiple sets of periodic control signals acquired within a preset period; based on this, in S20 above, "determining the tapping event according to the control signal" may include:

[0098] S201, perform data statistics on the control signal to obtain the statistical characteristics of the control signal, and determine the change characteristics of the control signal based on the statistical characteristics of the control signal;

[0099] S202, if there is a target change feature that meets the preset conditions, then determine the tapping event triggered by the target change feature.

[0100] In this embodiment, after the vehicle acquires the control signal, it can perform data statistics on the control signal to obtain the statistical characteristics of the control signal, and determine the change characteristics of the control signal based on the statistical characteristics.

[0101] Furthermore, the vehicle can determine the variation characteristics of the control signal based on the statistical characteristics of the periodic control signal.

[0102] Among them, it is understandable that, such as Figure 4-1 , 4-1 And the tapping characteristic curve constructed based on the above statistical characteristics shown in Figure 4-3 (this curve represents the linear relationship between the control signal and the acquisition time), Figure 4-1 The tapping event shown indicates that the user tapped the steering wheel once. Figure 4-2 The tapping event shown indicates that the user tapped the steering wheel twice. Figure 4-3 The illustrated tapping event shows the user tapping the steering wheel three times in a "two fast, one slow" pattern. After constructing the tapping characteristic curve, the vehicle can determine the change characteristics of the control signal based on this curve.

[0103] Specifically, for example, the change characteristics of the control signal in this embodiment may include the amount of change Δi and the rate of change, where the amount of change Δi is the vertical axis representing the data of the tapping characteristic curve, and the rate of change is the slope of the tapping characteristic curve. As can be seen from the figure, the amount of change of the tapping event is much smaller than the amount of change of the control signal when the user normally holds the steering wheel, and the rate of change of the tapping event is much larger than the rate of change when the user normally holds the steering wheel under the same acquisition time.

[0104] In this way, after the vehicle acquires the change feature, it can detect whether the change feature meets the corresponding preset conditions. If it is determined that the change feature meets the preset conditions, it can respond to the change feature meeting the preset conditions and determine that there is a slapping event within a preset period, so that the slapping feature of the slapping event can be determined based on the change feature in the future.

[0105] The aforementioned preset conditions may include the change in the control signal in the change characteristics being less than a preset first threshold and the change rate of the control signal in the change characteristics being greater than a preset second threshold.

[0106] Specifically, when the user is holding the steering wheel normally, the vehicle can collect the triggered control signals, perform data statistics on the control signals, and determine the amount of change in the control signals when the user is holding the steering wheel normally as the first threshold, and the rate of change of the control signals when the user is holding the steering wheel normally as the second threshold.

[0107] Furthermore, the control signal includes multiple sets of periodic control signals acquired within a preset period; in step S201, "performing data statistics on the control signal to obtain the statistical characteristics of the control signal, and determining the variation characteristics of the control signal based on the statistical characteristics of the control signal" may include:

[0108] S2011, For each cycle control signal, perform data statistics on the cycle control signal to obtain the statistical characteristics of the cycle control signal;

[0109] S2012, determine the variation characteristics of the periodic control signals based on the statistical characteristics of each periodic control signal.

[0110] It should be noted that, in this embodiment, when the user applies a tapping event to the steering wheel, the vehicle can use the complete duration required to apply one tapping event as a set of preset cycles, and generate a corresponding cycle control signal in the cycle.

[0111] Based on this, for each cycle of control signal, the vehicle can perform data statistics on the control signal of that cycle to obtain the statistical characteristics of the control signal of that cycle.

[0112] Specifically, for example, the control signal can be a set of current or voltage values. In this way, the vehicle can calculate the statistical characteristics such as the mean and variance (or standard deviation) of a set of data, and then determine the variation characteristics of the control signal based on these statistical characteristics.

[0113] Furthermore, after S2012 above, "determining the variation characteristics of the periodic control signal based on the statistical characteristics of each periodic control signal", it may include:

[0114] S2013, Extract the amount and rate of change from the target change features;

[0115] Based on this, the preset conditions include: the amount of change is less than a preset first threshold and the rate of change is greater than a preset second threshold. In S202 above, "if there is a target change feature that satisfies the preset conditions, then determine the tapping event triggered by the target change feature," includes:

[0116] S2021, if the amount of change is less than a preset first threshold and the rate of change is greater than a preset second threshold, then the tapping event triggered by the target change feature is determined.

[0117] It should be noted that, in this embodiment, as Figure 4-1 The tapping event shown (the user taps the steering wheel once) is assumed to contain 10 sets of data in one cycle of control signal. After processing the data for mean and variance, the linear relationship between the acquired value of the control signal (i.e., the change in the control signal in this embodiment) and the acquisition time is obtained. Among them, the acquired value △2 of the tapping characteristic is smaller than the data △2 when the hand is normally gripping the steering wheel (△1 > △2). The slope value of the acquired value is larger under the same acquisition time. In addition, the duration T2 of the tapping event is shorter than the duration T1 of the event when the hand is normally gripping the steering wheel (T1 > T2).

[0118] like Figure 4-2 The illustrated tapping event (the user taps the steering wheel twice consecutively) shows a linear relationship between the acquired control signal value and the acquisition time after the mean and variance are processed, assuming the control signal contains 10 sets of data in one cycle. The acquired values ​​of the two consecutive taps show smaller changes and a larger slope compared to normal hand grip. Furthermore, the change time is shorter and the number of changes is greater: △1>△2≈△2′. Additionally, the duration of the two taps is approximately the same (T2a≈T2b) and both are shorter than the duration T1 of normal hand grip on the steering wheel: T2a≈T2b. <T1。

[0119] like Figure 4-3The illustrated tapping event (the user taps the steering wheel three times at a frequency of two fast taps followed by one slow tap) shows a linear relationship between the measured value of the control signal (i.e., the change in the control signal in this embodiment) and the measurement time, assuming that the control signal in one cycle contains 10 sets of data. The measured value of the "2 fast + 1 slow" continuous tapping characteristic, compared to normal hand grip, exhibits: smaller change, shorter change time, and more changes. Overall, the slope value of the "2 fast + 1 slow" tapping data is larger, and the number of changes is greater: △1>△2≈△2′≈△2″. Furthermore, the duration of the two taps is basically the same (T2a≈T2b≈T2c) and both are shorter than the duration T1 of normal hand grip on the steering wheel: T2a≈T2b≈T2c. <T1。

[0120] According to the above explanation, when a vehicle determines whether the user's action on the steering wheel is a slapping event or another event (such as normal gripping of the steering wheel), it can make a judgment based on at least two aspects: the amount of change in the control signal and the rate of change of the amount of change (i.e., the slope of the aforementioned slapping characteristic curve). The amount of change in a slapping event is smaller and the rate of change is higher.

[0121] Thus, if the vehicle determines that the change amount is less than the preset first threshold and the change rate is greater than the preset second threshold, it can determine that a tapping event exists within the preset period. The determination method of the first threshold and the second threshold can refer to the above description, and will not be repeated here.

[0122] Therefore, in this embodiment, the vehicle can perform data statistics on the control signals, calculate the change characteristics of the control signals based on the statistical characteristics of the control signals, and identify the tapping events and the tapping characteristics of the tapping events based on the change characteristics and preset conditions. In this way, this embodiment can expand the recognition of tapping events through HOD to achieve richer tapping events and realize more complex and higher-level vehicle function control, rather than just simple function control such as audio control and Bluetooth control. Moreover, it is only determined as a tapping event when the change characteristics meet the preset conditions; otherwise, it can be classified as other events, avoiding the incorrect start and stop of the corresponding vehicle functions caused by the user accidentally touching the steering wheel.

[0123] In one embodiment, S30 above, "controlling the target vehicle according to the control command corresponding to the slapping event" may include:

[0124] S301, determine the striking characteristics of the striking event based on the target change characteristics;

[0125] S302, control the target vehicle according to the control command corresponding to the striking feature.

[0126] In this embodiment, according to the above description, when the vehicle acquires the target change feature, it can detect whether the target change feature meets the corresponding preset condition. If it is determined that the target change feature meets the preset condition, it can respond to the target change feature meeting the preset condition and determine that there is a slapping event within a preset period. Then, the vehicle can determine the slapping feature of the slapping event based on the target change feature and control the target vehicle according to the control command corresponding to the slapping feature.

[0127] It should be noted that, in this embodiment, the tapping features corresponding to the tapping event include, but are not limited to, the tapping frequency when the user taps the steering wheel, the tapping gesture used by the user (such as a single finger, half palm, etc.), and the tapping location (at least one of the regions A001, A002, A003, A004, and A005 mentioned above). The above are just some examples of tapping features; other tapping features may also be included, which will not be listed here.

[0128] Furthermore, the striking feature includes the striking frequency of the striking event; based on this, in S301 above, "determining the striking feature of the striking event based on the target change feature" may include:

[0129] S3011, Based on the target change characteristics, determine the tapping frequency and tapping time interval of the tapping event;

[0130] S3012, determine the tapping frequency of the tapping event based on the tapping frequency and the tapping time interval.

[0131] In this embodiment, based on the above description, the vehicle can construct a corresponding statistical feature model of the control signal, such as... Figures 4-1 to 4-3 The tapping characteristic curve is shown. Furthermore, based on the changing characteristics of the control signal in this tapping characteristic curve, the tapping frequency and tapping time interval of the tapping event can be determined.

[0132] by Figure 4-3 For example, the vehicle can determine the frequency of the slapping event as 3 times (△2, △2′, △2″) based on the slapping characteristic curve, and the time intervals between the three slaps are T2d and T2e, where T2d < T2e, that is, the user applied a "two fast and one slow" slapping event to the steering wheel.

[0133] Furthermore, the vehicle can determine the tapping frequency of the tapping event based on the tapping frequency and the tapping time interval. For example, the tapping frequency and the tapping time interval can be directly used as the tapping frequency of the tapping event.

[0134] Furthermore, the slapping features also include slapping location and slapping gesture; based on this, in S301 above, "determining the slapping features of the slapping event based on the target change features" may further include:

[0135] S3013, Based on the target change characteristics of the control signal, determine the striking position of the striking event, wherein the control signal includes multiple sets of control signals applied to different striking areas on the target object;

[0136] S3014, Based on the change characteristics, determine the contact area corresponding to the tapping event, wherein the contact area is the area in contact with the target object when the tapping event is applied;

[0137] S3015, determine the slapping gesture of the slapping event based on the contact area.

[0138] After identifying the user-applied tapping event by observing the changing characteristics of the control signal generated by the user tapping the steering wheel (i.e., the target object in this embodiment), the vehicle can not only identify the tapping frequency of the tapping event based on the tapping characteristic curve, but also determine the tapping position and tapping gesture based on the changing characteristics of the control signal.

[0139] It should be noted that, in this embodiment, according to the above description, the HOD system can use a capacitive sensor to collect the control signal triggered by the user. In this embodiment, a capacitive sensor can be set in at least one of the tapping areas A001 to A005.

[0140] If a capacitive sensor is set in only one area, the off-hand detection is a single-area recognition. In this scenario, the user can tap the tapping area with the capacitive sensor using gestures such as single finger, two fingers, multiple fingers, or half palm. The signal processing unit can recognize the user's different tapping intentions, and the tapping frequency will also be different when the number of taps per unit time is different, which can be used to distinguish more tapping intentions.

[0141] If capacitive sensors are set in multiple areas, the off-hand detection is multi-area recognition. In this scenario, the signal processing unit supports multi-channel processing. The control signals collected by each capacitive sensor are processed independently and are not affected by each other. Functions can be executed according to the set priority to avoid false triggering or function failure. At the same time, under specific conditions, multi-channel composite response time is also supported.

[0142] Based on this, the vehicle can identify the location of the slapping event according to the changing characteristics of the control signal. This control signal can be multiple sets of control signals applied by the user to different slapping areas on the steering wheel. It is understood that, as explained above, since the steering wheel is pre-divided into multiple slapping areas A001 to A005, the slapping location can be determined by identifying which specific slapping area triggered the control signal.

[0143] Furthermore, as described above, a capacitive sensor typically consists of multiple electrodes distributed on or inside the steering wheel. When the driver's hand touches the steering wheel, a capacitance is formed between the human body and these electrodes. By measuring the change in capacitance on these electrodes, the capacitive sensor can determine whether the driver's hand is on the steering wheel, and the location and area of ​​contact. Therefore, in this embodiment, the vehicle can calculate the contact area with the steering wheel when the user applies a tapping event based on the amount and rate of change of the control signal.

[0144] Specifically, for example, in this embodiment, the tapping event applied by the user on the steering wheel includes, but is not limited to, low-frequency tapping with two fingers, high-frequency tapping with two fingers, low-frequency tapping with half a palm, high-frequency tapping with half a palm, and high-frequency tapping with more than half a palm. This embodiment does not specifically limit the type of tapping event, and can be flexibly customized and developed according to user needs.

[0145] Furthermore, in S302 above, "controlling the target vehicle according to the control command corresponding to the striking feature" may include:

[0146] S3021, If ​​the tapping frequency in the tapping feature is higher than a preset frequency threshold, then the corresponding security level is determined based on the tapping gesture in the tapping feature.

[0147] S3022, Generate corresponding safety control commands based on the safety level to control the target vehicle.

[0148] It should be noted that, in this embodiment, the tapping method and the triggered vehicle function event can be customized, for example:

[0149] (1) Using a two-finger low-frequency tapping acquisition unit, it can be used to process some non-functional safety events, such as multimedia mode switching, volume adjustment, telephone answering, etc.

[0150] (2) Using two fingers to tap the acquisition unit at a high frequency can be used to process some functional events that need to transmit information to other users inside and outside the vehicle, such as voice reminders such as "Please fasten your seat belt" and "Do not stick your hands out of the window", or low-volume horn reminders to pedestrians and vehicles at close range.

[0151] (3) Using a half-palm low-frequency tapping acquisition unit, it can be used for some interactions outside the vehicle system and functional events that need to be considered for execution, such as ride-hailing users accepting orders with one click, and can complete the operation without touching the mobile phone.

[0152] (4) Using a half-palm high-frequency tapping acquisition unit, it can be used for some urgent functional events that need to be executed without much time to think, such as issuing a high-volume horn reminder when reminding emergency avoidance, or in the case of vehicle malfunction requiring emergency stopping.

[0153] (5) Using a high-frequency tap of more than half a palm to strike a specific acquisition unit can be used to handle some urgent functional events related to user personal safety, such as alarms or calls for help in case of unexpected working conditions.

[0154] Thus, in this embodiment, high-frequency taps can be defined as events related to safety incidents (in line with user behavior habits), different gestures (i.e., the contact area with the steering wheel) reflect different levels of urgency of the event (two fingers for a voice reminder to fasten the seat belt, half a palm for emergency avoidance, and above for an alarm), while low-frequency taps are all non-safety incidents.

[0155] Specifically, for example, after a vehicle identifies a tapping event, it can determine whether the tapping frequency of the event exceeds a preset frequency threshold. If the tapping frequency is found to be higher than the preset frequency threshold, the corresponding safety level can be determined based on the tapping gesture in the tapping characteristics.

[0156] Based on the slapping gesture in the slapping feature, the corresponding safety level is determined, and a corresponding safety control command is generated based on the safety level. The vehicle is then controlled according to the safety control command.

[0157] In addition, this embodiment can also pre-build a mapping table between tapping events and safety control commands. In this mapping table, each tapping event has a corresponding control command. For example, a high-frequency tapping with two fingers is mapped to a control command to remind the user to fasten their seat belt.

[0158] Therefore, this embodiment can identify the tapping frequency, tapping location, and tapping gesture of a tapping event by controlling the change characteristics of the control signal. Compared with traditional vehicle control based on the steering wheel, the tapping sensing based on the HOD system in this embodiment can not only distinguish the tapping intention by tapping location and tapping frequency, but also expand the gesture definition to a richer range through the recognition of gestures by HOD. This allows users to achieve more complex and higher-level control of the vehicle without taking their hands off the steering wheel.

[0159] In one embodiment, after "acquiring the control signal", S10 may further include:

[0160] S40, filter abnormal data in the control signal according to preset filtering rules;

[0161] S50, acquire the ambient temperature information corresponding to the control signal, and determine the target compensation value according to the ambient temperature information and the preset mapping relationship, wherein the preset mapping relationship includes the ambient temperature when the control signal is acquired and the corresponding compensation value, which is used to compensate for the control signal error caused by the ambient temperature;

[0162] S60, the filtered control signal is compensated according to the target compensation value, so as to process the compensated control signal.

[0163] It should be noted that, in this embodiment, considering the possibility of users accidentally touching the steering wheel, the control signal can be filtered before processing to improve control accuracy. Furthermore, as described above, the control signal collected by the capacitive sensor is actually a capacitance signal, and the change in capacitance signal is closely related to ambient temperature and humidity. Therefore, this embodiment can also control the ambient temperature during signal collection to compensate for the control signal, thereby eliminating the influence of the environment and hardware differences on the control signal, and further improving the control accuracy of the steering wheel and the vehicle.

[0164] Specifically, for example, the vehicle can filter out abnormal data in the control signal according to preset filtering rules, thereby filtering out abnormal control signals.

[0165] In this embodiment, the preset filtering rule may include: if each data in the control signal is within a preset filtering range, the filtering range may be determined based on the mean or median of the control signal. For example, a range may be determined first based on the mean or median of the control signal, and data in the control signal within the range may be retained while data outside the range may be removed to obtain the filtered control signal.

[0166] This allows for the collection of ambient temperature information, and the determination of the target compensation value based on the ambient temperature information and a preset mapping relationship.

[0167] In this embodiment, the mapping relationship can specifically be a temperature compensation lookup table, which can include the ambient temperature when the control signal is acquired and the corresponding compensation value, used to compensate for the control signal error caused by the ambient temperature.

[0168] Specifically, for example, according to such Figure 5-1 The table shown contains the average value of the control signal at various temperatures, and the difference between this average value and the average value calibrated at 20°C. This difference can be used as the compensation value for the control signal. Based on this, the following methods can be employed: Figure 5-2The temperature compensation lookup table shown contains the ambient temperature range of the control signal and the target compensation value ΔRef corresponding to that ambient temperature range.

[0169] For example, such as Figure 5-2 As shown, if the ambient temperature for acquiring the control signal is between -10°C and 10°C, then by consulting the temperature compensation lookup table, the target compensation value ΔRef can be determined to be -9.

[0170] Then, based on the target compensation value obtained from the query, the filtered control signal can be compensated.

[0171] For example, the target compensation value can be added to each data point in the collected control signal to obtain the compensated control signal.

[0172] In another embodiment, after compensating the filtered control signal, the compensated control signal can be first imported into a preset cache space, and it can be determined whether the data storage volume of the preset cache space reaches a preset threshold. When the data storage volume of the preset cache space reaches the preset threshold, the compensated control signal can be statistically analyzed to determine the change characteristics of the control signal. Conversely, when the data storage volume of the preset cache space does not reach the preset threshold, the control signal can be re-acquired for filtering and compensation, and the preset cache space can be updated until the data storage volume of the preset cache space reaches the preset threshold.

[0173] It is understandable that in this embodiment, the data cache space serves as a buffer for data storage. When the data is full, an event determination is performed, which can reduce the system's processing power consumption. If the data is processed in real time, there is a problem of high system power consumption, and it is impossible to filter out some abnormal conditions, such as occasional unintentional touches or light touches. The fact that the buffer is full serves as the standard for whether to process the event, which can filter out some abnormal conditions and reduce the system's processing power consumption.

[0174] Therefore, in this embodiment, by using data filtering and data compensation strategies, interference from user accidental touches is eliminated, as well as the influence of ambient temperature, hardware conditions, etc., on the control signal. This avoids the misidentification of tapping events caused by the aforementioned interference, significantly improves the control precision of the steering wheel, and thus effectively improves the control precision of the vehicle.

[0175] Therefore, in this embodiment, the tapping frequency, tapping position, and tapping gesture of the user's tapping event on the steering wheel can be identified. Each type of tapping event has a corresponding safety control command, which allows the user to achieve more complex and advanced control of the vehicle by simply operating the steering wheel, assisting the user in intelligent driving and ensuring safety during the driving process.

[0176] In general, such as Figure 6As shown, the vehicle control method in this embodiment may include at least the following:

[0177] (1) The HOD sensor acquisition unit periodically scans the changing values ​​in the system, generates raw data, and then sends it to the signal processing unit;

[0178] (2) The HOD sensor signal processing unit filters the raw data to remove abnormal data;

[0179] (3) The HOD signal processing unit collects environmental signals and determines whether the original data needs to be compensated. The temperature and humidity signals are from the vehicle input or the temperature and humidity sensor built into the steering wheel. The compensation data comes from historical calibration.

[0180] (4) The original data will be loaded into the data buffer of the processing unit after compensation. When the data stored in the buffer is full, the HOD processing unit will recognize it as an event.

[0181] (5) The HOD processing unit analyzes the characteristics of the data in this group, calculates its mean and variance (standard deviation), identifies the data change characteristics, fits it into a linear change, and calculates its slope value (i.e. rate of change).

[0182] (6) The HOD processing unit compares the change characteristics of the data with the calibrated threshold to determine the specific slapping event;

[0183] (7) The HOD processing unit transmits the corresponding time information to the steering wheel ECU, and then to the corresponding functional system of the vehicle to realize function triggering.

[0184] Thus, the steering wheel tap-sensing function in this embodiment is based on the HOD system, enabling users to conveniently perform multi-functional operations without taking their hands off the steering wheel while enjoying a safe driving environment. Compared to traditional steering wheel tap-sensing, the HOD-based tap-sensing not only distinguishes tapping intentions by tapping location and frequency, but also expands gesture definitions through HOD's gesture recognition, enabling more complex and advanced controls. The HOD-based tap-sensing system has more accurate anti-mistouch characteristics, and the software can effectively filter out invalid signals, more accurately recognizing the user's tapping intentions. In addition, the HOD system is integrated into the steering wheel switch circuit board, eliminating the need for external attachments to other parts of the steering wheel and reducing the space occupied inside the steering wheel. The detection positions are mainly distributed in the steering wheel rim area, providing wide and flexible coverage.
