These drawings and the textual description are not intended to limit the scope of the present application in any way, but rather to illustrate the concepts of the present application to those skilled in the art by reference to specific embodiments. DETAILED DESCRIPTION

[0091] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

[0092] With the development of society and economy, the number of vehicles in society has gradually increased. According to relevant regulations, when driving a vehicle, if you encounter a situation where you need to turn or change lanes, you need to turn on the vehicle's turn signal to signal other vehicles or people around you.

[0093] In some embodiments, the user typically makes a subjective judgment while driving, based on their driving intent, the vehicle's surroundings, and their driving situation. They then manually operate a lever or switch to control the turn signal. In exceptional circumstances, the turn signal may be accidentally activated or omitted. These exceptional circumstances may include, but are not limited to, emergency avoidance situations, poor driving habits, and unfamiliarity with road conditions. Improper control of the turn signal may pose a driving safety risk.

[0094] In the above embodiment, the control of the turn signal lamp requires manual control by the user, which has poor intelligence, thereby resulting in low safety for the user in driving the vehicle.

[0095] The model-based intelligent control method for turn signals provided in the embodiment of the present application collects multiple types of first information from a vehicle, wherein the first information can be used to determine whether the vehicle's turn signal needs to be turned on; based on at least one of the first information, if it is determined that the vehicle's turn signal needs to be turned on, the turn signal to be turned on is controlled to be turned on, so as to achieve automatic intelligent control of the vehicle's turn signal, improve the control intelligence of the turn signal, and thus achieve the effect of improving driving safety.

[0096] The following specific embodiments describe in detail the technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0097] Figure 1 Schematic diagram of the process of the automatic control method of the vehicle turn signal provided in this application Figure 1 ,like Figure 1 As shown, the method includes:

[0098] Step 101: Obtain first vehicle information.

[0099] The first information includes at least one of the following information: navigation information, steering wheel angle information of the vehicle steering wheel, and driver's eye image.

[0100] Exemplarily, first vehicle information is obtained from different systems. The first vehicle information is used to determine whether the vehicle needs to activate a turn signal. Specifically, the first vehicle information may include at least one of the following: navigation information, steering wheel angle information of the vehicle's steering wheel, and a driver's eye image.

[0101] Navigation information is transmitted via the vehicle's navigation map system. Based on the vehicle's current location, time, and navigation route, the vehicle's navigation map system can determine whether the vehicle is approaching an intersection, exit, or fork in the road, as well as whether the vehicle needs to change lanes to overtake, avoid a congested lane, or pull over. If the navigation map system determines based on this information that the vehicle needs to turn or change lanes, it generates navigation information.

[0102] Optionally, the navigation information indicates that the vehicle currently needs to turn and the direction of the turn.

[0103] The steering wheel angle information of the vehicle's steering wheel is sent via the Electric Power Steering (EPS) system, which can monitor the steering wheel angle of the vehicle in real time.

[0104] The driver's eye image is captured by cameras installed on both side mirrors outside the vehicle. For example, the camera on the left rearview mirror can directly capture images within a first preset viewing angle of the left rearview mirror, and the images within this first preset viewing angle include the eye area of ​​the user's face in the driver's seat; the camera on the right rearview mirror can directly capture images within a second preset viewing angle of the right rearview mirror, and the images within this second preset viewing angle also include the eye area of ​​the user's face in the driver's seat. It can be understood that since the vehicle's driving seat can be set on either the left or the right side, the above-mentioned first preset viewing angle and second preset viewing angle can be determined in combination with the actual application of the vehicle.

[0105] Step 102: If it is determined based on at least one of the first information that the vehicle's turn signal needs to be turned on, the turn signal to be turned on is controlled to be turned on.

[0106] Exemplarily, based on at least one piece of information in the first information, it is determined that the current vehicle needs to turn on a turn signal, and then the turn signal to be turned on is controlled to be turned on.

[0107] For example, when the first information contains one type of information, whether the current vehicle's turn signal needs to be turned on is determined based on the first information. When the first information contains multiple types of information, whether the current vehicle's turn signal needs to be turned on can be determined based on one or more types of information in the first information. Furthermore, after determining that the vehicle's turn signal needs to be turned on based on the first information, the first information can also be used to determine which turn signal to turn on, thereby controlling the vehicle's turn signal to be turned on.

[0108] The embodiment of the present application provides a method for automatically controlling a vehicle's turn signal, which collects multiple types of first information from the vehicle, wherein the first information can be used to determine whether the vehicle's turn signal needs to be turned on; based on at least one of the first information, if it is determined that the vehicle's turn signal needs to be turned on, the turn signal to be turned on is controlled to be turned on, so as to achieve automatic intelligent control of the vehicle's turn signal, improve the control intelligence of the turn signal, and eliminate the need for the user to manually combine the driving situation and the surrounding conditions of the vehicle to make judgments and operations, thereby improving driving safety.

[0109] As can be seen from the above embodiments, whether the vehicle needs to turn on the turn signal can be determined based on at least one piece of first information. Specifically, this embodiment describes how to determine whether the vehicle needs to turn on the turn signal based on each piece of first information.

[0110] In one example, if it is determined that the navigation information indicates that the vehicle needs to turn in a first direction, it is determined that a turn signal located in the first direction of the vehicle needs to be turned on.

[0111] For example, as can be seen from the aforementioned examples, navigation information is determined by the vehicle's navigation map system based on the vehicle's current location information, time information, and navigation route. For example, the navigation map system determines, based on the vehicle's current location information, time information, and navigation route, that the vehicle is approaching a fork in the road and needs to make a left turn at the fork, and thus generates navigation information. This navigation information indicates that the vehicle needs to turn left. Therefore, it determines that the vehicle's left turn signal needs to be activated.

[0112] For another example, when the navigation map system determines that the vehicle has arrived at the destination and needs to pull over to the right, it generates navigation information. The navigation information indicates that the vehicle needs to turn right to pull over to the right. Therefore, it is determined that the right turn signal of the vehicle needs to be turned on.

[0113] In one possible scenario, if the navigation route indicates that the vehicle should turn right at the current intersection, but the position information indicates that the vehicle is in a straight lane, the navigation map system will not generate navigation information indicating that the vehicle needs to turn right.

[0114] In one example, if it is determined that the steering wheel angle information of the vehicle steering wheel indicates that the vehicle steering wheel is turning in a first direction, it is determined that a turn signal located in the first direction of the vehicle needs to be turned on.

[0115] For example, as shown in the preceding example, the steering wheel angle information is sent by the vehicle's electric power steering system. In practical applications, the steering wheel angle information is typically a set of discrete data points arranged in chronological order, each representing the steering wheel angle at that moment.

[0116] If it is determined based on the steering wheel angle information that the steering wheel of the vehicle is turning in a first direction, it is determined that a turn signal located in the first direction of the vehicle needs to be turned on.

[0117] Specifically, if it is determined that the steering wheel angle indicated by the steering wheel angle information is greater than or equal to a preset angle threshold within a preset range and the angle of the steering wheel toward the first direction is greater than or equal to a preset angle threshold, then it is determined that the steering wheel angle information of the vehicle steering wheel indicates that the vehicle steering wheel is turning toward the first direction.

[0118] Exemplarily, when the steering wheel angle information indicates that the steering wheel angle is turned toward the first direction from a preset range by an angle greater than or equal to a preset angle threshold, it indicates that the steering wheel angle information indicates that the vehicle steering wheel is turning toward the first direction.

[0119] In practical applications, a vehicle's steering wheel can typically rotate left and right, and has a neutral position. The middle value of the preset range is the steering wheel angle corresponding to the neutral position. For example, the steering wheel angle at the neutral position is 0°. For example, a steering wheel angle turning left is a negative value. The preset range can be set to -3° to 3°. It will be understood that when the steering wheel angle falls within the range of -3° to 3°, it indicates that the steering wheel is not turning.

[0120] If the steering wheel angle is rotated within a preset range toward a first direction and exceeds a preset angle threshold, it indicates that the steering wheel is turning toward the first direction. For example, if the first direction is the left and the preset angle threshold is 30°, if the steering wheel angle continues to turn leftward within the preset range and exceeds or equals 30°, it indicates that the vehicle's steering wheel is turning left.

[0121] In one example, if it is determined that the driver's eye image indicates that the driver is looking at a rearview mirror located in a first direction of the vehicle, it is determined that a turn signal located in the first direction of the vehicle needs to be turned on.

[0122] For example, in combination with the above examples, it can be seen that the driver's eye image is collected by the camera of the two side rearview mirrors outside the vehicle. Based on the driver's eye image, it can be determined whether the driver is looking at the rearview mirror of the vehicle.

[0123] Specifically, both the left and right rearview mirrors on the vehicle's exterior can capture images of the driver's eyes. If the driver's eye image captured by the left rearview mirror indicates that the driver is looking at the left rearview mirror, then it is determined that the vehicle's left turn signal needs to be activated. It will be appreciated that if the driver's eye image captured by the right rearview mirror indicates that the driver is looking at the right rearview mirror, then it is determined that the vehicle's right turn signal needs to be activated.

[0124] Furthermore, if it is determined that the duration of the driver's eye sight in the driver's eye image being located at the rearview mirror in the first direction of the vehicle is greater than or equal to a preset first time threshold, then it is determined that the driver's eye image indicates that the driver is looking at the rearview mirror in the first direction of the vehicle.

[0125] For example, based on the driver's eye image, the location where the driver's eye gaze is located in the driver's eye image can be extracted. If the location is determined to be within the range of the rearview mirror in the first direction, the driver is determined to be in the rearview mirror gaze state, and a timer is started to determine the duration that the driver's eye gaze is located within the rearview mirror in the first direction of the vehicle.

[0126] If it is determined that the duration is greater than or equal to a preset first time threshold, the eye image representing the current driver indicates that the driver is looking at a rearview mirror located in a first direction of the vehicle.

[0127] It should be noted that the first time threshold can be set according to actual application. The first time threshold should not be set too small, otherwise it may cause an erroneous judgment of turning on the turn signal, nor should it be set too large, otherwise it may cause a delay in turning on the turn signal.

[0128] It should also be noted that the above examples can be implemented individually or in combination. It is understood that when the conditions provided by any of the above three examples are met, it is determined that the vehicle currently needs to turn on the turn signal.

[0129] In the above embodiment, the need to activate the vehicle's turn signals is determined based on multiple types of first information. Specifically, navigation information can indicate whether the vehicle needs to turn according to navigation instructions; steering wheel angle information can indicate whether the user is steering; and the driver's eye image can indicate whether the user is looking in the rearview mirror in preparation for turning. This determination based on multiple types of first information can more comprehensively and accurately cover scenarios where the vehicle's turn signals require activation. By comprehensively and accurately covering these scenarios, the vehicle's turn signals are automatically activated, improving the intelligence of the vehicle's turn signal control. Furthermore, automated turn signal control eliminates the need for manual judgment and operation, thereby enhancing driving safety.

[0130] Based on the aforementioned embodiment, in one example, the steps of determining whether it is necessary to turn on the vehicle's turn signal based on the first information and controlling the turn signal to turn on can be performed through an artificial intelligence model.

[0131] Specifically, the first information is input into the prediction model for processing to obtain the turning intention; wherein the turning intention indicates whether the vehicle needs to turn.

[0132] Based on the prediction model, if it is determined that the turning intention indicates that the vehicle needs to turn, a first control signal is generated and sent to a controller of the turn signal to control the turn signal to be turned on.

[0133] Exemplarily, the first information is input into a prediction model for prediction processing, and a turning intention is obtained based on the first information based on the prediction model. The turning intention indicates whether the vehicle currently needs to turn.

[0134] Optionally, when the turning intention indicates that the vehicle needs to turn, the turning intention may also indicate the direction in which the vehicle needs to turn.

[0135] Furthermore, if it is determined based on the prediction model that the turning intention indicates that the vehicle needs to turn, a first control signal is generated. The first control signal is used to control the turn signal to be turned on. The turn signal to be turned on is the turn signal for the direction indicated by the turning intention.

[0136] For example, based on the prediction model, when it is determined that the vehicle needs to turn left based on any one of navigation information, steering wheel angle information of the vehicle steering wheel, and the driver's eye image, a first control signal is generated and sent to the controller of the turn signal.

[0137] The controller of the turn signal controls the left turn signal of the vehicle to turn on based on the first control signal.

[0138] Optionally, the prediction model can be a pre-trained model, and real-time training data is acquired while the vehicle is driving. The real-time training data can be the acquired first information, and the first information has the corresponding turn signal operating state. The prediction model is continuously trained based on the real-time training data to ensure the prediction model's accuracy in predicting turning intentions.

[0139] In the above example, the predictive model identifies and determines the first information to determine the turn intention. Based on the turn intention, a control signal is then generated to cause the turn signal controller to activate the turn signal. By introducing an intelligent model, the first information can be combined to more accurately identify the turn intention and continuous training can be performed while the vehicle is driving, further improving the intelligent control of the vehicle's turn signal.

[0140] Furthermore, based on the aforementioned embodiment, in addition to the intelligent automatic control of turning on the vehicle's turn signal, the brightness of the turn signal may also be controlled.

[0141] In one example, the first information also includes: external environment information and actual brightness information of the turn signal.

[0142] Exemplarily, a composite sensor is also provided outside the vehicle. The composite sensor may include a rain sensor and a light sensor. The rain sensor is used to detect rainfall outside the vehicle, while the light sensor is used to detect light intensity outside the vehicle. Based on the rainfall and light intensity, external environmental information can be obtained. This external environmental information is used to characterize the environmental conditions outside the vehicle. For example, the external environment outside the vehicle may be daytime, nighttime, or when driving in a tunnel.

[0143] Exemplarily, the controller of the turn signal lamp may also read actual brightness information of the turn signal lamp, where the actual brightness information represents the brightness of the turn signal lamp when it is turned on.

[0144] Based on the external environment information and the actual brightness information of the turn signal, when the turn signal needs to be turned on, the brightness of the turn signal that needs to be turned on can be determined.

[0145] Figure 2 Schematic diagram of the process of the automatic control method of the vehicle turn signal provided in this application Figure 2 ,like Figure 2 As shown, this embodiment Figure 1 Based on the embodiment, step 102 is described in detail. The method includes:

[0146] Step 201: Generate a brightness signal according to external environment information and actual brightness information.

[0147] Exemplarily, a brightness signal is generated according to the vehicle's external environment conditions represented by the external environment information.

[0148] Specifically, if the external environment information indicates that the vehicle's external environment is daytime, the brightness of the turn signal indicated by the generated brightness signal is a first brightness; if the external environment information indicates that the vehicle's external environment is nighttime or a tunnel, the brightness of the turn signal indicated by the generated brightness signal is a second brightness. The second brightness is greater than the first brightness.

[0149] Furthermore, if the external environmental information indicates that the external environment of the vehicle is daytime, and the actual brightness information of the turn signal indicates that the brightness of the turn signal is not the first brightness, the generated brightness signal indicates that the brightness of the turn signal is adjusted to the first brightness; if the external environmental information indicates that the external environment of the vehicle is night or a tunnel, and the actual brightness information of the turn signal indicates that the brightness of the turn signal is not the second brightness, the generated brightness signal indicates that the brightness of the turn signal is adjusted to the second brightness.

[0150] Furthermore, the process of generating brightness signals can also be performed through artificial intelligence models.

[0151] Specifically, the external environment information and the actual brightness information of the turn signal are input into the prediction model for processing to generate a brightness signal.

[0152] Exemplarily, the external environment information and the actual brightness information of the turn signal are input into the prediction model for processing to generate a brightness signal corresponding to the external environment information and the actual brightness information of the turn signal.

[0153] For example, if the external environmental information indicates that it is currently night and the rainfall is heavy, when the prediction model generates a brightness signal, the brightness of the turn signal indicated by the brightness signal is the third brightness, which is greater than the second brightness in the aforementioned example.

[0154] Optionally, the prediction model can be a pre-trained model, and real-time training data is acquired while the vehicle is driving. The real-time training data can be acquired external environmental information and actual brightness information of the turn signal, where the external environmental information and the actual brightness information of the turn signal have corresponding turn signal activation brightness. The prediction model is continuously trained based on the real-time training data to ensure the accuracy of the prediction model's determination of brightness information.

[0155] In the above example, the AI ​​model determines the brightness signal based on the external environment and actual brightness information. This model accurately combines the external environment and actual brightness to intelligently determine the required brightness for the turn signal. When the external lighting conditions are good, the turn signal brightness is reduced to save energy. When the external lighting conditions are poor, the turn signal brightness is increased to ensure that the turn signal clearly warns surrounding vehicles and personnel, improving driving safety.

[0156] Step 202: If it is determined based on at least one of the first information that the vehicle's turn signal needs to be turned on, the turn signal to be turned on is controlled, and the brightness of the turn signal to be turned on is controlled to be the brightness indicated by the brightness signal.

[0157] Exemplarily, in combination with the above example, if it is determined based on at least one information in the first information that the vehicle's turn signal needs to be turned on, the turn signal to be turned on is controlled to be turned on, and the brightness of the turn signal to be turned on is controlled to be the brightness indicated by the brightness signal.

[0158] For example, based on the first information, it is determined that the left turn signal needs to be turned on. Based on the external environment information, it is determined that the current external environment of the vehicle is night and the brightness information of the left turn signal is 0. A first control signal and a brightness signal are generated and sent to the turn signal controller, so that the controller controls the left turn signal to turn on at a second brightness.

[0159] In the above embodiment, a brightness signal can be determined based on external environmental information and the actual brightness information of the turn signal, and the brightness of the turn signal can be controlled based on the brightness information. The brightness of the turn signal can be flexibly adjusted based on the vehicle's external environment. For example, when the external light intensity is sufficient, the brightness can be reduced to save energy.

[0160] In some cases, when the vehicle needs to turn on the turn signal, the user has already manually turned on the turn signal. At this time, you only need to control the brightness of the turn signal; or when the vehicle needs to turn on the turn signal in the first direction, the user manually turns on the turn signal in the second direction by mistake. You can intelligently control the turn signal in the first direction to turn on, control the brightness of the turn signal in the first direction, and control the turn signal in the second direction to turn off.

[0161] Specifically, in one example, before controlling the turn signal lamp to be turned on, the method further includes:

[0162] Get the actual status of the turn signal. The actual status includes the actual status of the turn signal to be turned on and the actual status of the turn signal that does not need to be turned on.

[0163] For example, the actual state of the turn signal can be read by the turn signal controller, wherein the actual state includes the actual state of the turn signal on both sides of the vehicle, that is, the actual state of the turn signal to be turned on and the actual state of the turn signal not to be turned on.

[0164] For example, if it is determined according to the first information that the left turn signal needs to be turned on, the actual state of the turn signal to be turned on is whether the left turn signal is already turned on, and the actual state of the turn signal that does not need to be turned on is whether the right turn signal is already turned on.

[0165] In one example, if it is determined that the actual state of the turn signal lamp to be turned on is on, the brightness of the turn signal lamp to be turned on is controlled to be the brightness indicated by the brightness signal.

[0166] For example, since the vehicle is also equipped with a turn signal switch with a manual lever, the user can still manually control the turn signal. If it is determined that the actual state of the turn signal to be turned on is on, there is no need to further control the turn signal to be turned on. It is only necessary to control the brightness of the turn signal to be turned on to the brightness indicated by the brightness signal based on the brightness signal.

[0167] In one example, if it is determined that the actual state of the turn signal lamp that does not need to be turned on is on, the turn signal lamp that does not need to be turned on is controlled to be turned off.

[0168] For example, in one possible scenario, the vehicle needs to turn on the left turn signal, but the user mistakenly turns on the right turn signal. Based on the vehicle's need to turn on the left turn signal, the vehicle's left turn signal is controlled to turn on, and the brightness of the left turn signal is controlled to the brightness indicated by the brightness signal. Based on this, the right turn signal is controlled to turn off.

[0169] It should be noted that the above two examples can be implemented separately or in combination.

[0170] In the above embodiment, the actual opening status of the vehicle's turn signal can be combined, and when the correct turn signal is turned on, the opening brightness can be adjusted to save energy; when the wrong turn signal is turned on, not only the wrong turn signal is controlled to be turned off, but also the correct turn signal is controlled to be turned on, and the opening brightness is adjusted, thereby further improving the control intelligence of the vehicle's turn signal, avoiding user misoperation, and improving the driving safety of the vehicle.

[0171] As can be seen from the above embodiments, in the above embodiments, how the vehicle controls the intelligent turning on of the turn signal is explained. After the vehicle completes the turn, the turn signal can be intelligently and automatically controlled to be turned off.

[0172] Figure 3 Schematic diagram of the process of the automatic control method of the vehicle turn signal provided in this application Figure 3 ,like Figure 3As shown, based on any of the above examples, the method further includes:

[0173] Step 301: Obtain second information of the vehicle.

[0174] The second information includes at least one of the following information: navigation information, steering wheel angle information of the vehicle steering wheel, and turn signal activation time information.

[0175] Exemplarily, the second vehicle information is obtained from different systems. The second vehicle information is used to determine whether the vehicle has completed a turn. Specifically, the second vehicle information may include at least one of the following: navigation information, steering wheel angle information of the vehicle steering wheel, and turn signal activation time information.

[0176] The navigation information is sent via the vehicle's navigation map system, and the steering wheel angle information of the vehicle's steering wheel is sent via the electric power steering system. The specific process can be found in the description of step 101 in the aforementioned embodiment.

[0177] The turn signal on time information is sent by the turn signal controller. After the turn signal controller turns on the turn signal, it can perform timing to obtain the turn signal on time information.

[0178] Step 302: If it is determined based on at least one of the second information that the turn signal of the vehicle needs to be turned off, the turn signal to be turned off is controlled to be turned off.

[0179] Exemplarily, based on at least one piece of information in the second information, it is determined that the current vehicle needs to turn off a turn signal, and then the turn signal to be turned off is controlled to be turned off.

[0180] For example, when the second information contains one type of information, whether the current vehicle needs to turn off the turn signal is determined based on the second information; when the second information contains multiple types of information, whether the current vehicle needs to turn off the turn signal can be determined based on one or more types of information in the second information.

[0181] In the above embodiment, multiple types of second information are collected from the vehicle, wherein the second information can be used to determine whether the vehicle's turn signal needs to be turned off; based on at least one of the second information, if it is determined that the vehicle's turn signal needs to be turned off, the turn signal to be turned off is controlled to be turned off, so as to achieve automatic intelligent control of the vehicle's turn signal, improve the control intelligence of the turn signal, and no longer need the user to manually combine the driving situation and the surrounding conditions of the vehicle to determine whether the turn signal needs to be turned off, thereby improving driving safety.

[0182] As can be seen from the above embodiments, whether the vehicle needs to turn off the turn signal can be determined based on at least one of the second information. Specifically, this embodiment describes how to determine whether the turn signal needs to be turned on based on each type of second information.

[0183] In one example, if it is determined that the navigation information indicates that the vehicle does not need to turn, it is determined that the vehicle's turn signal needs to be turned off.

[0184] For example, as can be seen from the above examples, navigation information is determined by the vehicle's navigation map system based on the vehicle's current location information, time information, and navigation route. If the navigation information indicates that the vehicle does not need to turn and this information persists for a certain period of time, it is determined that the vehicle has completed the turn, i.e., the vehicle's turn signal needs to be turned off.

[0185] It is understandable that if the navigation map system does not prompt the driver to turn within a certain period of time, it is considered that the current vehicle has completed the turn and the vehicle's turn signal needs to be turned off.

[0186] In one example, if it is determined that the steering wheel angle information of the vehicle indicates that the steering wheel of the vehicle is in a return-to-center state, it is determined that the turn signal of the vehicle needs to be turned off.

[0187] For example, in conjunction with the above example, the steering wheel angle information is sent by the vehicle's electric power steering system. Based on the steering wheel angle information, if it is determined that the steering wheel angle information indicates that the vehicle's steering wheel is in the return state, it is determined that the vehicle's turn signal needs to be turned off.

[0188] Specifically, if it is determined that the steering wheel angle indicated by the steering wheel angle information is within a preset range for a duration greater than or equal to a preset third time threshold, then it is determined that the vehicle's steering wheel angle information indicates that the vehicle's steering wheel is in a return-to-center state.

[0189] For example, in combination with the above example, the middle value of the preset range is the steering wheel angle corresponding to the neutral position. When the steering wheel angle falls within the preset range, it indicates that the steering wheel is not turning, that is, in the return state.

[0190] Furthermore, if it is determined that the steering wheel angle indicated by the steering wheel angle information is within a preset range, a timer is started to determine the duration that the steering wheel angle indicated by the steering wheel angle information is within the preset range. If it is determined that the duration is greater than or equal to a preset third time threshold, it is determined that the steering wheel angle information of the vehicle indicates that the vehicle steering wheel is in the return-to-center state.

[0191] Optionally, during the process of determining whether the vehicle's steering wheel is in the return-to-center state, the determination process may be further refined. For example, if it is determined that the steering wheel angle indicated by the steering wheel angle information returns from outside a preset range to within the preset range and remains within the preset range for a duration greater than or equal to a preset third time threshold, then the vehicle's steering wheel angle information is determined to indicate that the vehicle's steering wheel is in the return-to-center state.

[0192] It should be noted that the third time threshold can be set according to actual application. The third time threshold should not be set too small, otherwise it may cause an erroneous judgment of turning off the turn signal, nor should it be set too large, otherwise it may cause a delay in turning off the turn signal.

[0193] In one example, if it is determined that the turn signal light's turn signal light-on time information indicates a turn signal light-on time greater than or equal to a preset second time threshold, it is determined that the turn signal light of the vehicle needs to be turned off.

[0194] For example, in combination with the above examples, it can be seen that the turn signal on time information is sent by the turn signal controller. The turn signal on time represents the duration of the vehicle's turn signal on state.

[0195] If it is determined that the turn-on time indicated by the turn-on time information is greater than or equal to a preset second time threshold, it indicates that the vehicle's turn signal has been turned on for a period of time. At this time, it can be determined that the vehicle's turn signal needs to be turned off.

[0196] It should be noted that the second time threshold can be set based on actual application. The second time threshold should not be set too low, otherwise the turn signal may be turned off before the vehicle completes the turn, nor should it be set too high, otherwise the turn signal may not be turned off after the vehicle completes the turn and enters the straight lane.

[0197] It should also be noted that the above multiple examples can be implemented separately or in combination. It is understood that when the conditions provided by any of the above three examples are met, it is determined that the vehicle currently needs to turn off the turn signal.

[0198] In the above embodiment, multiple types of second information are used to determine whether the vehicle's turn signals need to be turned off. Specifically, navigation information can indicate whether the vehicle needs to turn; steering wheel angle information can indicate whether the steering wheel has returned to the center position; and turn signal on-time information can indicate how long the vehicle's turn signals have been on. This determination based on multiple types of second information can more comprehensively and accurately cover scenarios where the vehicle's turn signals need to be turned off. By comprehensively and accurately covering these scenarios, the vehicle's turn signal off control is automatically controlled, improving the intelligence of the vehicle's turn signal control. Furthermore, automated control eliminates the need for manual judgment and operation, thereby improving driving safety.

[0199] Based on the aforementioned embodiment, in one example, the steps of determining whether it is necessary to turn off the vehicle's turn signal based on the second information and controlling the turn signal to turn off can be performed through an artificial intelligence model.

[0200] Specifically, the second information is input into the prediction model for processing to obtain a prediction result; wherein the prediction result indicates whether the vehicle has completed the turn.

[0201] Based on the prediction model, if it is determined that the prediction result indicates that the vehicle has completed the turn, a second control signal is generated and sent to the controller of the turn signal to control the turn signal to be turned off.

[0202] Exemplarily, the second information is input into a prediction model for prediction processing, and a prediction result is obtained based on the second information based on the prediction model. The prediction result indicates whether the vehicle has currently completed the turn.

[0203] Furthermore, if the prediction result indicates that the vehicle has completed the turn based on the prediction model, a second control signal is generated. The second control signal is used to control the turn signal to be turned off. The turn signal to be turned off is the turn signal in the current state, and the actual state is the turn signal on.

[0204] For example, based on the prediction model and steering wheel angle information, if the duration of the vehicle's steering wheel angle remaining within a preset range exceeds a third time threshold, this indicates that the vehicle has completed a turn and the turn signal needs to be turned off. A second control signal is generated and sent to a controller for the turn signal.

[0205] The controller of the turn signal controls the turn signal of the vehicle that is in the turned-on state to be turned off based on the second control signal.

[0206] Optionally, the prediction model can be a pre-trained model, and real-time training data is acquired while the vehicle is driving. The real-time training data can be the acquired second information, and the second information includes the corresponding operating state of the turn signal. The prediction model is continuously trained based on the real-time training data to ensure the prediction accuracy of the prediction model with respect to the prediction results.

[0207] Optionally, when it is determined that the turn signal of the vehicle needs to be turned off, the actual state of the turn signal is obtained from the controller of the turn signal. If the actual state of the turn signal to be turned off is off, the second control signal is not generated.

[0208] In the above example, the prediction model identifies and judges the first person information to obtain a prediction result. Based on the prediction result, a control signal is then generated to cause the turn signal controller to turn the turn signal off. By introducing an intelligent model, the prediction result can be more accurately identified by combining the second person information, and continuous training can be performed while the vehicle is driving, further improving the intelligent control of the vehicle's turn signal.

[0209] The embodiment of the present application provides a method for automatically controlling the vehicle's turn signal, which obtains first information and controls the vehicle's turn signal to turn on when it is determined based on the first information that the vehicle's turn signal needs to be turned on; and obtains second information and controls the vehicle's turn signal to turn off when it is determined based on the second information that the vehicle's turn signal needs to be turned off. This achieves automated control of the vehicle's turn signal, improves the intelligence of steering control, and eliminates the need for manual judgment and operation, thereby improving driving safety. Furthermore, when it is determined that the vehicle's turn signal needs to be turned on, a brightness signal is determined based on the vehicle's external environmental information and the actual brightness of the turn signal, and the brightness of the vehicle's turn signal is controlled based on the brightness signal. This can reduce the brightness of the turn signal when there is sufficient light, thereby achieving energy saving. In addition, by introducing an intelligent model into the vehicle, the accuracy of controlling the turn signal can be further improved by using the intelligent model to determine whether the vehicle's turn signal needs to be turned on or off based on the first information and the second information.
