Abstract
Description
Technical Field
[0001] This invention relates to the field of electric vehicle control technology, and in particular to an interactive system for electric two-wheeled vehicles based on resistive touch switches. Background Technology
[0002] Existing electric two-wheeler interaction systems have the following technical shortcomings:
[0003] 1) Limitations of mechanical switches: Most switches on electric two-wheeled vehicles are mechanical switches. Mechanical switches have limited interaction functions and cannot support complex interactions; they have low reliability, are susceptible to environmental corrosion and wear, and have a short lifespan.
[0004] 2) Limitations of Capacitive Touch Switches: Capacitive touch switches, which have emerged in recent years, work by sensing the electrical current of the human body. They detect the touch location through the tiny capacitance formed between the electrodes on the touchscreen and the finger. While capacitive touch switches offer relatively rich and intelligent interactive functions, this interaction method is costly and has poor anti-interference capabilities. For example, they cannot recognize control commands in rainy weather or when operating with gloves.
[0005] 3) Fixed functions: Usually, one gesture corresponds to one function, which cannot support complex interactions and has low fun. Summary of the Invention
[0006] To address the aforementioned problems and technical needs, the inventors have proposed an interactive system for electric two-wheeled vehicles based on resistive touch switches. To overcome the limitations of traditional mechanical switches in electric two-wheeled vehicles, which lack both functionality and intelligence, this system utilizes resistive touch switches and custom gesture logic to support single-point, multi-point combinations, and swipe combinations for triggering vehicle control operations. The technical solution of this invention is as follows:
[0007] An interactive system for electric two-wheeled vehicles based on resistive touch switches is disclosed. The system includes resistive touch switches and core electrical components on the vehicle side. The two interact with each other through wired and wireless communication on the vehicle body to realize single-point triggering, multi-point combination triggering, and sliding combination triggering of corresponding vehicle body control actions.
[0008] A further technical solution is that the resistive touch switch includes:
[0009] The screen-printed function panel, FPC, and resistance sensor are arranged from top to bottom. The resistance sensor is used to receive physical press signals and convert them into contact information.
[0010] The pressure-sensitive integrated chip is used to collect contact information, which is then converted by an analog-to-digital converter and sent to the main control MCU.
[0011] The main control MCU is used to analyze the validity of contact information and match corresponding control commands for valid contact information, which are then sent to the core electrical components on the vehicle in the form of messages to execute the control commands.
[0012] The further technical solution is that single-point triggering of corresponding body control actions refers to short-pressing, long-pressing, or double-clicking the silkscreen icon of the resistive touch switch to execute basic body control functions.
[0013] A further technical solution is that multi-point combination triggering of corresponding body control actions refers to simultaneously touching and pressing the silkscreen icons of multiple resistive touch switches to execute intermediate body control functions.
[0014] A further technical solution is that the sliding combination triggers the corresponding vehicle body control action by touching and pressing the plus / minus silkscreen icon of the resistive touch switch and sliding it in one direction to perform the adjustment function of the vehicle body dynamic parameters, including stepless adjustment of vehicle speed, current and headlight brightness.
[0015] The further technical solution is that the system also includes a user-end APP, which interacts with the resistive touch switch via wireless communication. The system also implements custom gesture learning and input functions.
[0016] The further technical solution involves the following steps in implementing the customized gesture learning and input function:
[0017] Collect user touch records and extract touch point information features, including touch point coordinates, touch duration, and pressure value;
[0018] Logical training is performed on the touch point information features to update the gesture and control command mapping table;
[0019] The gesture and control command mapping table is saved to the main control MCU for gesture logic updates, or sent to the user-end APP for synchronous push.
[0020] A further technical solution involves performing logical training on the touch point information features to update the gesture and control command mapping table, including:
[0021] CNN is used to identify gesture trajectories based on the characteristics of touch point information;
[0022] The KNN algorithm is used to match historical gestures and control commands that are similar to the current gesture trajectory from the original gesture and control command mapping table.
[0023] If a match cannot be found, the current gesture trajectory is defined as a new gesture, and the control command it implements is recorded in the gesture and control command mapping table.
[0024] The further technical solution involves implementing the custom gesture learning and input function, which also includes:
[0025] The main control MCU automatically adjusts the gesture priority in the gesture and control command mapping table according to the frequency of touch operation, and automatically lights up the backlight of the panel silkscreen icons with higher priority.
[0026] The further technical solution involves implementing the custom gesture learning and input function, which also includes:
[0027] The cloud determines the user's operation category based on the characteristics of touch information, and pushes the corresponding gesture and control command mapping table to the user's app according to the user's operation category;
[0028] If the user-side APP chooses to accept the gesture and control command mapping table pushed to the main control MCU, the gesture logic will be updated via OTA.
[0029] The beneficial technical effects of this invention are:
[0030] The electric two-wheeler interaction system of this application adopts a resistive touch switch, which can achieve precise contact point coordinate detection through pressure touch control. It supports operation with gloves and wet hands, and has low hardware cost. It can realize complex intelligent control by performing single-point, multi-point, and sliding combination operations. The acrylic panel of the resistive touch switch, together with the function silkscreen icons, realizes accurate touch switch function. Compared with the glass substrate of capacitive screen, the acrylic panel material has better durability and impact resistance (>5J), improving the switch's environmental adaptability (waterproof, dustproof, and vibration resistant). Through the cooperation of the resistive touch switch and the user-end APP, it supports the input of custom touch gestures, realizing the customization of switch interaction functions.

[0036] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.
[0037] One embodiment of this application provides an interactive system for an electric two-wheeled vehicle based on a resistive touch switch, such as... Figure 1 As shown, the system includes a resistive touch switch and core vehicle-side electrical components. The resistive touch switch consists of a silkscreened function panel, an FPC, a resistance sensor, a pressure-sensitive integrated chip, and a main control MCU. It interacts with the core vehicle-side electrical components via wired and wireless communication with the vehicle body, meeting the requirements of low-cost, high-quality, and intelligent design for electric two-wheelers. It can realize single-point triggering, multi-point combination triggering, and sliding combination triggering of corresponding vehicle body control actions, as well as custom gesture learning and input functions. Optionally, the core vehicle-side electrical components include a motor controller, a battery management system, a lighting controller, an instrument display, and a vehicle body VCU.
[0038] Combination Figure 2 As shown, the screen-printed function panel, FPC, and resistance sensor are arranged from top to bottom. In one possible implementation, the FPC is preferably a capacitor copper foil FPC; the screen-printed function panel is preferably made of acrylic panel material and can be integrated near the speed control throttle for convenient user operation, such as... Figure 3 As shown; except Figure 2 Besides the structure of the resistive sensor shown, other existing resistive sensor structures can also be used as replacements, and there are no restrictions on this. The working principle of the resistive touch switch is as follows: When the user of the electric two-wheeled vehicle touches ① the function silkscreen icon on the panel, a physical pressing signal is generated. This signal is converted into contact information via a copper foil FPC and a resistive touch sensor circuit. The pressure-sensitive integrated chip ② collects the contact information, and after AD conversion, it is sent to the main control MCU ③ through IIC and GPIO ports. The main control MCU analyzes the validity of the contact information, discards invalid contact information, and matches corresponding control commands for valid contact information. These commands are then sent in message form ④ to the core electrical components on the vehicle side ⑤ to execute the control commands and achieve the corresponding vehicle body movement control effect. The contact information includes at least the contact coordinate position, touch duration, and pressure value.
[0039] The touch logic design of the electric two-wheeler interaction system based on resistive touch switches is as follows:
[0040] 1) Single-point trigger: Short press, long press or double-click the silkscreen icon of the resistive touch switch to perform basic vehicle control functions.
[0041] 2) Multi-point combination triggering: Simultaneously touching and pressing the silkscreen icons of multiple resistive touch switches executes intermediate-level vehicle control functions. In one possible implementation, a short press of the parking icon... To enter parking mode, briefly press the hazard light icon. Pressing the turn signal flashing warning button will activate the vehicle's anti-skid TCS mode; pressing the parking icon and hazard light icon simultaneously will activate the vehicle's anti-skid function in rainy weather.
[0042] 3) Slide combination trigger: Touch the plus / minus silkscreen icon on the resistive touch switch and slide it in one direction to perform dynamic parameter adjustment functions for the vehicle body, including stepless adjustment of vehicle speed, current, and headlight brightness. In one possible implementation, such as Figure 4 As shown, the logic for triggering a single cruise control and continuously variable speed control combination via a sliding combination includes: while riding at a speed of 30km / h, touching and pressing the cruise control button... When the icon is pressed, the main control MCU parses and recognizes the cruise control command, sends a valid trigger message to the vehicle's motor controller and instrument panel, and enters cruise control mode. The vehicle speed is then fixed at 30 km / h, and the cruise control mode is displayed on the instrument panel. In cruise control mode, a single touch of the "+" icon triggers the main control MCU to send a valid plus sign message to the motor controller, increasing the current cruise speed by N = 5 km / h, resulting in a cruise speed of 35 km / h. Holding the "+" icon for 1 second and then sliding it to the right to the middle position of the "+" and "-" icons, holding for T = 3 seconds, and then releasing the touch enables continuous cruise speed increments, increasing the cruise speed by T × N = 15 km / h, resulting in a cruise speed of 50 km / h. Similarly, by touching and pressing the "-" icon for 1 second and then sliding it to the left to the middle position of the "+" and "-" icons, holding for T=3 seconds and then lifting it, the speed can be continuously reduced by T×N=15km / h, that is, riding at a constant speed of 20km / h.
[0043] The electric two-wheeler interaction system based on resistive touch switches also includes a user-end app. The app interacts with the resistive touch switches wirelessly to enable the system to learn and input custom gestures. For example... Figure 5 As shown, it specifically includes the following:
[0044] ① Collect and store user touch records: Collect and store the contact information and operation frequency of the user's operation of the resistive touch switch button. The contact information includes the coordinate position, time, pressure value, gesture trajectory and touch combination (such as short press + swipe, double press + long press, etc.) of each touch. Store the user touch records to the local EEPROM of the main control MCU or the cloud (optional).
[0045] ② Touch point information feature extraction: Based on information such as coordinate position, touch duration, and pressure value in the touch point information, the time interval of each touch press can be extracted (e.g., two clicks with an interval of <300ms are double clicks), touch area (e.g., large touch area is judged as glove operation), and pressure value (light pressure vs. heavy pressure, used to trigger different command functions). Optionally, the cloud can use a clustering algorithm to classify user operation features, such as Category 1: high-frequency single click (suitable for beginners), Category 2: swipe gestures (suitable for experienced users), and Category 3: long press + gesture combination (suitable for professional cyclists), for subsequent accurate push notifications.
[0046] ③ Perform logical training on the touch point information features to update the gesture and control command mapping table. Specifically, based on the previously collected touch point information features, a mapping logic decision tree for gestures and control commands can be constructed to form an initial gesture and control command mapping table. When the training cycle arrives, a CNN is used to identify the gesture trajectory from the latest extracted touch point information features. Then, the KNN algorithm is used to match historical gestures and control commands similar to the current gesture trajectory from the original gesture and control command mapping table. If no match is found, the current gesture trajectory is defined as a new gesture, and the corresponding control commands are recorded in the gesture and control command mapping table for gesture logic update.
[0047] ④ Save the gesture and control command mapping table to the local main control MCU for gesture logic updates, or send it to the user's APP for synchronous push.
[0048] For the gesture logic update and push of the main control MCU, when the main control MCU receives the latest gesture and control command mapping table, it automatically adjusts the gesture priority in the gesture and control command mapping table according to the touch operation frequency, and automatically lights up the backlight of the silk screen icons with higher priority to adapt to the user's operation frequency.
[0049] For synchronized push notifications to the user-side app, once the cloud determines the user's operation category, it pushes the corresponding gesture and control command mapping table to the user-side app. Users can choose whether to accept updates (e.g., "industry-recommended gesture logic") in the app. If they choose to accept the pushed gesture and control command mapping table, it is pushed via OTA (Over-the-Air), such as through Bluetooth / Wi-Fi / 4G, to update the gesture logic by writing it to the main control MCU. Optionally, users can also view the recommended gesture logic in the app and manually issue control commands to synchronize with the vehicle's main control MCU for gesture logic updates. A notification will appear on the vehicle's instrument panel / app indicating "Gesture logic updated." Users can then perform actual touch operations to verify if the vehicle's control actions match and determine if retraining is necessary.
[0050] As can be seen from the above-described various implementation methods, the electric two-wheeler interaction system provided in this application utilizes an integrated design of a matrix resistive touchscreen and silkscreen printing. Furthermore, the resistive touch switch is coated and encapsulated to achieve waterproofing, dustproofing, and corrosion resistance, thereby realizing an intelligent combination switch application for the electric two-wheeler. The integrated design of the resistive touch switch and gesture logic enables a low-cost, intelligent, and highly stable switch combination logic for the electric two-wheeler, including single-point, multi-point, and sliding combinations, as well as custom gesture learning logic software algorithm applications. This can automatically optimize the mapping between gestures and functions and push optimized logic.
[0051] The above descriptions are merely preferred embodiments of this application, and the present invention is not limited to the above embodiments. It is understood that other improvements and variations directly derived or conceived by those skilled in the art without departing from the spirit and concept of the present invention should be considered to be included within the protection scope of the present invention.
