[0002] With the continuous innovation of new energy vehicle technology and the deepening of the intelligent trend, an obvious change is the trend of removing hard switches, which is reshaping the operating interface and user experience inside the car. In traditional cars, the interior of the vehicle is full of various physical buttons and switches, which are responsible for various functions of vehicle control, from air conditioning adjustment to window lifting; however, under the wave of intelligence, these unnecessary hard switches are gradually being eliminated, and replaced by more integrated and intelligent solutions.

[0003] Nowadays, more and more new energy vehicles have shifted their operation centers to smart large screens.

Through the smart large screen, users can easily complete a series of operations such as navigation settings, entertainment system control, and vehicle status monitoring, which greatly simplifies the cumbersome process of traditional physical buttons. At the same time, the introduction of the voice command system has brought the intelligence level of new energy vehicles to a new height. Users can achieve comprehensive control of the vehicle through simple verbal commands, whether it is adjusting the temperature in the car, opening and closing the windows, or checking the driving route and playing music. This new interactive method not only improves the safety during driving, but also brings unprecedented convenience and fun to users.

DETAILED DESCRIPTION

[0026] In order to further understand the content of the present invention, the present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the embodiments are only for explaining the present invention and are not intended to limit it.

[0027] The following is an explanation of the technical terms involved in the present invention: ICM (Instrument Cluster Module) refers to a central control screen integrated in a car, usually used to display various vehicle information and provide entertainment functions. ICM is a vehicle information display and control module, which receives data from various vehicle sensors, integrates and displays it on the screen, such as vehicle speed, engine status, fuel consumption and other information.

[0028] Example 1 As described in the background technology, at present, more and more new energy vehicles have transferred the operation center to the smart large screen. This screen, which integrates advanced display technology and touch function, not only provides clear and intuitive vehicle information display, but also gives users a more convenient and rich interactive experience. Through the smart large screen, users can easily complete a series of operations such as navigation settings, entertainment system control, and vehicle status monitoring, which greatly simplifies the cumbersome process of traditional physical buttons. At the same time, the introduction of the voice command system has raised the intelligence level of new energy vehicles to a new height. Users only need to use simple verbal commands to achieve comprehensive control of the vehicle, whether it is adjusting the temperature in the car, opening and closing the windows, or checking the driving route, playing music, it can be easily done. This new interactive method not only improves the safety during driving, but also brings unprecedented convenience and fun to users. However, the use of the above-mentioned interactive method has also caused complaints from many users. On the one hand, some users have a deep-rooted dependence on traditional physical buttons. They are accustomed to confirming the completion of operations through touch and press, and feel uncomfortable with the new way of interaction such as smart large screens and voice commands. On the other hand, the stability and accuracy of smart large screens and voice command systems are also the focus of users. Once a failure or misidentification occurs, it may pose a potential threat to driving safety.

[0029] In order to solve the above problems, this embodiment provides a control method for turn signals based on steering wheel operation. This method provides a supplementary method for controlling turn signals of electric vehicles, which replaces the operation of hard switches by detecting the driver's tapping action on the steering wheel; thereby helping users to better use vehicle functions.

[0030] This embodiment provides a control method for a turn signal lamp based on steering wheel operation, comprising: The first step is to collect a knocking action signal; the knocking action signal is generated by knocking a knocking sensing area on the steering wheel; Step 2: Based on the tapping action signal and the preset signal strength threshold, a valid tapping action signal is screened and obtained; Step 3: When receiving at least a preset number of valid knocking action signals in the same direction within a preset time, an execution request signal is sent so that the actuator can control the turn signal to turn on or off according to the execution request signal.

[0031] This control method collects the knock action signal of the knock sensing area on the steering wheel, and selects the effective knock according to the preset signal strength threshold. When the effective knock action signal is received in the same direction for a preset number of times within the preset time, it immediately triggers the execution request of turning the turn signal on or off. The use of this control method effectively solves the stability and accuracy problems of the existing smart large screen and voice command control of turn signals, providing users with a more intuitive and reliable interactive experience that meets the dependence of some users on traditional physical operations, thereby significantly improving the safety during driving and the overall driving experience of users. The design method provided by this embodiment is further explained below in conjunction with the accompanying drawings: like Figure 1 As shown, this embodiment provides a control method for a turn signal based on steering wheel operation, and the specific implementation process is as follows: In this embodiment, the vehicle needs to be equipped with a steering wheel with force-sensing feedback sensors installed at the three o'clock and nine o'clock positions to support the detection of user finger tapping actions. The detection areas are on the left and right sides, namely the first orientation area and the second orientation area, and the two are symmetrically arranged; it should be noted that the preferred implementation scheme is as follows: a circle of force-sensing feedback sensors can also be installed with the center of the steering wheel as the center; whether the steering wheel is in the normal position or in the steering position, the driver's left-hand side area is used as the first orientation area for collecting tapping action signals; the driver's right-hand side area is used as the second orientation area for collecting tapping action signals; in this way, no matter what operation the user is in, the left-hand area side is the control side of the left turn signal; the right-hand area side is the control side of the right turn signal, which enhances the user's driving experience.

[0032] In this embodiment, the user action is two or three quick taps; and the ICM screen can be used to bind the operation effects of different actions in different areas. A total of four quick function operations can be set. The left and right turn signal is a default bundled function for tapping twice, which can be changed later through the ICM screen.

[0033] Combination Figure 3 As shown, this embodiment provides a control system based on steering wheel operation of turn signal, including force sensing feedback sensor, ICM large screen, domain controller; this control system uses capacitive sensing steering wheel to operate and control the turn signal, and the specific method is as follows: The force sensing feedback sensor is used to detect the driver's knocking action greater than 6N and send a signal to the ICM large screen; that is, in this embodiment, the preset signal force threshold is 6N; The ICM large screen is used to turn on and off and change the motion detection function of the steering wheel. At the same time, it receives signals from the force sensing feedback sensor to determine whether the knocking action signal is valid and sends a corresponding request signal to the domain controller. At the same time, it receives feedback signals from the domain controller and displays the execution results.

[0034] The domain controller is used to receive the request signal from the ICM large screen and send execution request signals to the left and right turn signals; at the same time, it receives the feedback signals from the left and right turn signals.

[0035] The left and right turn signals are used to receive the execution request signal from the domain controller, execute the opening and closing actions, and feedback the signal to the domain controller.

[0036] This embodiment provides a control method for a turn signal lamp based on steering wheel operation, and a more specific implementation process is as follows: Combination Figure 1 and Figure 2 As shown in FIG. 1 , the knock sensing area on the steering wheel is the area between 8 o'clock and 10 o'clock and between 2 o'clock and 4 o'clock. Figure 2 The red area in the figure; the effective trigger action signal is the action of the finger tapping the sensing area with a force greater than 6N, twice or three times, and a total of four functions can be set to trigger.

[0037] The prerequisites of this control method are: a: the vehicle is powered on, and b: the corresponding action function is bound through the ICM large screen.

[0038] The trigger condition is: the ICM large screen receives two or three knock signals greater than 6N from the same force sensing feedback sensor in the steering wheel within 1 second.

[0039] The force sensing feedback sensor is set to detect effective left and right knocking action signals greater than 6N in the specified area, which are divided into Lfunctionarea=0x1 and Rfunctionarea=0x1. When the ICM large screen detects two (or three) consecutive knocking action signals in the same direction within 1 second, the ICM large screen sends an execution signal to the corresponding actuator through the domain controller, and the vehicle executes the binding action in the corresponding knocking action area.

[0040] Execution output: tap the left side twice with a force greater than 6N, the ICM large screen sends a turn signal on to the left turn signal through the domain controller, the left turn signal is turned on, the light status signal is sent to the ICM large screen through the domain controller, the ICM large screen displays, and the next operation is to close; tap the right side twice with a force greater than 6N, the ICM large screen sends a turn signal on to the right turn signal through the domain controller, the right turn signal is turned on, the light status signal is sent to the ICM large screen through the domain controller, the ICM large screen displays, and the next operation is to close.

[0041] Example 2 like Figure 4 As shown, this embodiment provides a control method for a turn signal lamp based on steering wheel operation, comprising the following steps: Collecting a knocking action signal; the knocking action signal is generated by knocking a knocking sensing area on the steering wheel; Based on the tapping action signal and the preset signal strength threshold, a valid tapping action signal is screened and obtained; When at least a preset number of valid knocking action signals are received in the same direction within a preset time, an execution request signal is sent so that the actuator can control the turn signal to turn on or off according to the execution request signal.

[0042] In this embodiment, the specific steps of screening and obtaining a valid tapping action signal based on the tapping action signal and the preset signal strength threshold include: The collected tapping action signal is compared with the preset signal strength threshold. If the tapping action signal is greater than the preset signal strength threshold, the tapping action signal is filtered and output; otherwise, the tapping action signal is ignored. The preset signal strength threshold is used to filter the effective tapping action signal, ensuring that only taps with sufficient strength are recognized as valid operations, thereby avoiding the possibility of misoperation; this screening mechanism improves the accuracy and response speed of the system, making the control of the turn signal more precise and reliable.

[0043] Here, the specific steps of sending the execution request signal when receiving at least a preset number of valid tapping action signals in the same direction within a preset time include: Receive the filtered effective knocking action signal, and identify the position of the effective knocking action signal; If valid tapping action signals from the same direction are identified at least a preset number of times within a preset time, an execution request signal is sent; otherwise, no response is made.

[0044] By identifying the direction and counting the number of times, the system can accurately identify the user's intention and send an execution request signal in a timely manner when the conditions are met. This method not only improves the system's response speed, but also enhances the convenience of user operation.

[0045] Here, the knock sensing area includes at least a first orientation area and a second orientation area; wherein the first orientation area and the second orientation area are symmetrically arranged on the steering wheel.

[0046] Symmetrical tapping sensing areas are set on the steering wheel, such as the first orientation area and the second orientation area, so that the user can control the turning light on or off by tapping different positions of the steering wheel; this not only conforms to the principles of ergonomics, improves the comfort and convenience of user operation, but also helps to improve safety and stability during driving.

[0047] Specifically, the specific steps of the actuator controlling the turn signal to turn on or off according to the execution request signal are as follows: Generate a left turn control signal and a right turn control signal according to the received execution request signal, and transmit them to the domain controller; The domain controller turns the left turn signal on or off according to the received left turn control signal, or turns the right turn signal on or off according to the received right turn control signal.

[0048] The domain controller precisely controls the turn signal according to the received execution request signal, realizing the automation and intelligence of turning the turn signal on or off. This method not only improves the response speed and accuracy of the system, but also helps to reduce energy consumption and extend the service life of the equipment; at the same time, the introduction of the domain controller also makes it possible to realize more intelligent functions in the future.

[0049] like Figure 5 As shown, the present embodiment also provides a control system for steering wheel-operated turn signals, including: a signal acquisition module, used to acquire knocking action signals; the knocking action signals are generated by knocking on a knocking sensing area on the steering wheel; a signal screening module, used to screen and obtain effective knocking action signals based on the knocking action signals and a preset signal strength threshold; a control execution module, used to send an execution request signal when receiving at least a preset number of effective knocking action signals in the same direction within a preset time, so that the actuator can control the turn signal to turn on or off according to the execution request signal.

[0050] The present invention also provides a device, comprising: a memory for storing a computer program; and a processor for implementing the steps of the control method of a turn signal lamp based on steering wheel operation when executing the computer program.

[0051] When the processor executes the computer program, the above-mentioned steps of controlling the turn signal based on steering wheel operation are implemented, for example: collecting a knocking action signal; the knocking action signal is generated by knocking a knocking sensing area on the steering wheel; based on the knocking action signal and a preset signal strength threshold, a valid knocking action signal is screened and obtained; when at least a preset number of valid knocking action signals are received in the same direction within a preset time, an execution request signal is sent, so that the actuator can control the turn signal to turn on or off according to the execution request signal.

[0052] Alternatively, the processor implements the functions of each module in the above-mentioned system when executing the computer program, for example: a signal acquisition module, used to collect knocking action signals; the knocking action signals are generated by knocking on the knocking sensing area on the steering wheel; a signal screening module, used to screen and obtain effective knocking action signals based on the knocking action signals and a preset signal strength threshold; a control execution module, used to send an execution request signal when receiving at least a preset number of effective knocking action signals in the same direction within a preset time, so that the actuator can control the turn signal to turn on or off according to the execution request signal.

[0053] Exemplarily, the computer program can be divided into one or more modules / units, and the one or more modules / units are stored in the memory and executed by the processor to complete the present invention. The one or more modules / units can be a series of computer program instruction segments that can complete the preset functions, and the instruction segments are used to describe the execution process of the computer program in the control device based on the steering wheel to operate the turn signal. For example, the computer program can be divided into a signal acquisition module, a signal screening module and a control execution module; the specific functions of each module are as follows: a signal acquisition module, which is used to collect a knocking action signal; the knocking action signal is generated by knocking the knocking sensing area on the steering wheel; a signal screening module, which is used to filter and obtain an effective knocking action signal based on the knocking action signal and the preset signal strength threshold; a control execution module, which is used to send an execution request signal when receiving at least a preset number of effective knocking action signals in the same direction within a preset time, so that the actuator can control the turn signal to turn on or off according to the execution request signal.

[0054] This system collects the knock action signal generated by the knock sensing area on the steering wheel through the signal acquisition module, and uses the signal screening module to screen out the effective knock action signal according to the preset signal strength threshold. The control execution module then sends an execution request signal after receiving at least a preset number of effective knocks in the same direction within a preset time. Finally, the actuator controls the turn signal to turn on or off according to the signal. The use of this system not only retains the intuitiveness and reliability of physical interaction, avoids the possible misidentification and failure risks of smart large screens and voice command systems, but also provides an interaction method that is more in line with user operating habits, significantly improving the safety during driving and the user's overall driving experience.

[0055] In addition, the force sensing feedback sensor can collect tapping action signals in real time and immediately compare them with the preset threshold, so as to quickly screen out valid tapping action signals; this reduces the delay in signal processing and enables the system to respond to user operations more quickly.

[0056] As a more preferred embodiment, the system sets at least two force sensing feedback sensors on the steering wheel, and the sensors are respectively set in the first orientation area and the second orientation area, and the first orientation area and the second orientation area are symmetrical to each other. In this way, the control system can realize accurate recognition and distinction of tapping actions in different areas of the steering wheel, which not only improves the flexibility and accuracy of the system, but also enables the user to control the turning on or off of the turn signal by tapping different areas of the steering wheel; for example, tapping the left area controls the left turn signal, and tapping the right area controls the right turn signal, which also enhances the scalability and adaptability of the system; in the future, the functions and performance of the system can be further expanded by adding more sensors or adjusting the layout of the sensors; in addition, this symmetrical design is also in line with the principles of ergonomics, and improves the user's operating comfort and satisfaction.
