Technical Field
[0001] This invention belongs to the field of electronic communication technology, specifically relating to a racing car remote control and a Formula One racing car. Background Technology
[0002] With the rapid development of modern electronic control and wireless communication technologies, remote control devices have been widely used in industrial control, intelligent transportation, autonomous driving, and racing. Especially in high-performance racing scenarios such as Formula One racing, higher demands are placed on the stability, real-time performance, and security of remote control. Traditional racing remote controls mainly implement basic start-stop control and direction adjustment functions, typically using radio frequency or Wi-Fi for signal transmission. The operator sends commands to the race car receiver via buttons to complete the corresponding actions. These remote controls have a simple structure, only possess one-way communication capabilities, cannot obtain feedback on the race car's operating status, and have a limited human-machine interaction method, lacking intuitive status indicators and information display mechanisms.
[0003] In existing technologies, remote controls generally lack the ability to monitor and provide feedback on the racing car's operating status in real time. Operators find it difficult to promptly grasp whether the vehicle is in critical states such as high-voltage operation, emergency braking, or low battery warnings, posing safety hazards. In addition, traditional remote controls lack an integrated status display module, failing to provide visual information on the remote control's own attitude, remaining battery power, and other operating parameters, affecting control accuracy and ease of use.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.
[0019] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.
[0020] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0021] To address the technical deficiencies mentioned in the background section, this embodiment provides a racing car remote control and a Formula One racing car.
[0022] The present invention will now be described in further detail with reference to the accompanying drawings: like Figures 1-2 As shown, in a first aspect of the present invention, a racing car remote controller is provided, comprising: a housing with a hollow structure, housing an MCU controller, a wireless transmission module, and an integrated status monitoring module, wherein the MCU controller is electrically connected to the wireless transmission module and the integrated status monitoring module; the integrated status monitoring module is remotely connected to the racing car via the wireless transmission module; wherein the integrated status monitoring module includes a master switch, an LED indicator group, and a display component, wherein the master switch is electrically connected to the LED indicator group and the display component; the LED indicator group is used to indicate the current driving status information of the racing car; the display component is used to display the current status information of the MCU controller.
[0023] Through the above technical solution, this application achieves dual visual monitoring of the racing car's operating status and the remote control's own working status, improving information transparency and response timeliness during remote control.
[0024] The racing car remote controller adopts a modular design. By integrating the MCU controller, wireless transmission module and integrated status monitoring module into the same housing and establishing an electrical connection between the three, an intelligent control terminal with two-way communication and status feedback capabilities is constructed.
[0025] The housing, serving as the structural carrier, employs a hollow design, creating an internal space for mounting various electronic components and circuit board assemblies. The exterior can be ergonomically optimized with curved surfaces to enhance grip comfort. This housing can be made of high-strength plastic materials, such as PLA or other engineering plastics with excellent impact and temperature resistance, ensuring structural integrity is maintained even under complex environments such as vibration and drops.
[0026] As the core control unit, the MCU controller is responsible for coordinating the data processing and command scheduling tasks of the entire remote control. It receives operation signals from the buttons and status data from the sensors, and sends control commands to the race car through the wireless transmission module, while receiving feedback information from the race car.
[0027] The MCU controller also undertakes the responsibility of driving and managing the integrated status monitoring module, and dynamically updates the content of the LED indicator group and display components based on the received status data.
[0028] The MCU controller can be a microcontroller based on the ARM Cortex-M series architecture, featuring low power consumption and high real-time performance. It supports multiple communication interface protocols, such as UART, SPI, and I2C, which facilitates efficient interconnection with other modules.
[0029] The wireless transmission module is used to realize long-distance wireless communication between the remote controller and the race car. One end of the module is electrically connected to the MCU controller, and the other end radiates radio frequency signals outward through the antenna. The module can modulate the digital control signals output by the MCU into radio electromagnetic waves and transmit them to the race car receiver via the antenna; at the same time, it can also receive status feedback signals from the race car, demodulate and decode them, and send them to the MCU for processing.
[0030] In practice, this wireless transmission module supports multiple wireless communication standards, including but not limited to LoRa, Wi-Fi, ZigBee, or Bluetooth protocols, to adapt to the transmission distance and anti-interference requirements of different application scenarios. In particular, when using LoRa technology, an effective communication distance of over 1000 meters can be achieved, making it suitable for large outdoor racetrack environments.
[0031] The integrated status monitoring module establishes a remote communication connection with the race car through a wireless transmission module, thereby obtaining the race car's operating parameters. This module includes a master switch, a group of LED indicators, and a display component, which are connected by circuitry to form a unified functional subsystem.
[0032] The main switch, acting as the power on / off control node, regulates the power supply path to the LED indicator group and display components, ensuring the normal operation of related display functions when the device is on. This main switch can be a mechanical toggle switch or an electronic relay control switch, possessing excellent conduction stability and lifespan reliability.
[0033] The LED indicator array provides users with quick visual cues about the race car's current status, such as readiness to start, high-voltage operation, and emergency braking. It consists of multiple independently controlled light-emitting diodes, each corresponding to a specific state. Information is differentiated through color, flashing frequency, and other methods, allowing users to quickly identify the current control mode without needing to look at the screen, thus improving operational response speed.
[0034] The display component is used to present more detailed system information, especially the current status information of the MCU controller itself, such as remaining power, communication status, fault codes, attitude angle, etc. The display component can use OLED, LCD or other types of display screens, which have high contrast, wide viewing angle and low power consumption characteristics, and are suitable for clear reading in strong light or low light environments.
[0035] Through the above technical solution, this application realizes the transformation of the remote control from a single command transmitter to an intelligent control terminal with status perception and feedback capabilities. By integrating an MCU controller, a wireless transmission module, and an integrated status monitoring module, and establishing a collaborative working mechanism among the three, the remote control can not only send control commands, but also receive and display the racing car's operating status and its own system's health status in real time. Therefore, it solves the problem that traditional remote controls cannot provide effective status feedback, and significantly improves the safety, convenience, and human-computer interaction experience of the operation process.
[0036] This solution also includes a power switch, which is built into the housing and connected to the MCU controller and the main switch; the LED indicator group includes a switch assembly and a status indicator assembly, one end of the switch assembly is connected to the main switch and the other end is connected to the status indicator assembly; when the power switch is pressed, the status indicator assembly lights up to show the corresponding status between the switch assembly and the race car, while the display assembly shows the current remaining power and current status of the MCU controller.
[0037] By setting up an electrical linkage structure between the built-in power switch, main switch, and MCU controller, and in conjunction with the modular design of the LED indicator group, synchronous feedback of multi-dimensional status information is achieved when the remote control is started, which improves the user's ability to perceive the device's operating status, and enhances the safety and intuitiveness of control, especially in complex operating scenarios.
[0038] The power switch, as the start / stop control component for the entire remote control, is integrated inside the housing. Its output terminals are electrically connected to the MCU controller and the main switch respectively. When the user presses the power switch, the power supply circuit is triggered to conduct, powering on the MCU controller and other functional modules. At the same time, the power-on signal is transmitted to the main switch, thereby activating the working process of the integrated status monitoring module.
[0039] The power switch can be implemented using a tactile push-button switch or a toggle switch. Optionally, a mechanical button with a self-locking function can be selected to prevent accidental power outages caused by accidental touches.
[0040] In other alternative embodiments, the power switch can also be replaced with an inductive proximity switch or a magnetic switch to achieve on / off control in a non-contact manner, which is suitable for high-protection-level application environments.
[0041] The LED indicator group is divided into two functional sub-units: a switch assembly and a status indicator assembly. The switch assembly, as an input actuator, is used to send control commands to the system. One end of the switch assembly is connected to the main switch, forming a transmission path for the control signal; the other end is connected to the status indicator assembly, forming a status feedback loop. This establishes a direct mapping relationship between the operation and the visual feedback, improving the logical clarity of human-computer interaction.
[0042] Switching components can include various physical operating elements, such as buttons, knobs, or slide switches, and their specific forms can be configured according to actual operating requirements. For example, spring-return buttons can be used in scenarios requiring rapid response, while rotary-locking switches can be used in conditions requiring a stable state.
[0043] The status indicator assembly serves as an output display unit, used to present the racing car's operating status corresponding to the switch assembly. When the power switch is closed, the main switch receives the start signal and drives the status indicator assembly to light up, displaying the current status information of each control channel. This not only reflects whether the power supply has been successfully connected, but also simultaneously reflects the communication readiness status between the switch assembly and the racing car control system.
[0044] The status indicator assembly can be arranged in an array of multiple independently controlled light-emitting diodes (LEDs), with each LED corresponding to a specific operating mode, such as low-voltage preparation, high-voltage operation, and emergency stop protection.
[0045] In practical implementation, LEDs can be surface-mounted to save space, mounted on the PCB board and aligned with the light-transmitting window on the housing to ensure effective light leakage; in addition, a light guide structure can be added to guide the LED light source to a designated position on the housing surface, improving appearance consistency and viewing angle.
[0046] The display component works synchronously after the power is turned on, displaying the current remaining power and operating status of the MCU controller in real time. This function relies on the periodic sampling of the battery voltage by the analog-to-digital converter (ADC) integrated inside the MCU, combined with the preset voltage-power lookup table to perform table lookup calculations, and finally output the calculation results to the display component. The remaining power information is displayed in the form of a percentage value or a graphical progress bar, which makes it easy for users to quickly judge the battery life.
[0047] Current status information includes, but is not limited to, the MCU's operating mode, communication link status, and sensor data update frequency, helping users to understand the health status of the remote control itself.
[0048] In abnormal situations, such as detecting low voltage, communication interruption, or hardware failure, the display component can also pop up an alert, further enhancing the system's fault tolerance.
[0049] Through the above technical solution, this application achieves that the status indicator component lights up immediately upon pressing the power switch to reflect the logical correspondence between the switch component and the racing car. At the same time, the display component synchronously displays the remaining power and current operating status of the MCU controller. By introducing a linkage mechanism between the power switch, the main switch, and the MCU controller, and by decoupling the functions and optimizing the structure of the LED indicator group, users can fully grasp the status of the remote control itself and the connection preparation with the racing car at the initial stage of device startup. This effectively solves the problem of the lack of real-time status feedback after the traditional remote control is turned on, avoids operational errors caused by insufficient power or incorrect establishment of control signals, and significantly improves the safety and convenience of use.
[0050] Furthermore, the status indicator assembly includes a low-voltage status indicator, a high-voltage status indicator, an emergency stop status indicator, and a battery warning status indicator; the switch assembly includes an emergency stop knob, a low-voltage switch, and a high-voltage switch. The emergency stop knob is connected to the emergency stop status indicator, the low-voltage switch is connected to the low-voltage status indicator, and the high-voltage switch is connected to the high-voltage status indicator. Specifically, pressing the power switch illuminates the low-voltage status indicator to indicate that the low-voltage switch is on and the race car is in a low-voltage ready-to-start state; pressing the power switch illuminates the high-voltage indicator to indicate that the high-voltage switch is on and the race car is in a high-voltage forward-moving state; pressing the power switch illuminates the emergency stop status indicator to indicate that the emergency stop knob is on and the race car is in an emergency braking state; pressing the power switch illuminates and flashes the battery warning status indicator to indicate that the MCU controller is in a low-battery state.
[0051] The above structure provides a refined status feedback mechanism for racing car remote controllers. By setting up multiple sets of dedicated indicator lights and corresponding operation switches with electrical linkage, it can provide intuitive and visual prompts for the key operating status of the racing car. It is suitable for high-performance remote control scenarios that require rapid judgment of equipment operating conditions and can effectively improve the safety and response efficiency of user operation.
[0052] The status indicator assembly is used to provide clear visual feedback to operators, and includes four functionally independent indicator lights: low voltage status indicator, high voltage status indicator, emergency stop status indicator, and power warning status indicator.
[0053] Each indicator light corresponds to a specific working or abnormal state, ensuring clear and unambiguous information. For example, the low-voltage indicator light indicates whether the race car has completed its initial power-on and entered a standby state before starting; the high-voltage indicator light reflects whether the powertrain system has been activated and whether the vehicle is drivable; the emergency stop indicator light warns that the safety circuit has been cut off and the control system has triggered the emergency braking logic; and the battery warning indicator light indicates that the power supply to the remote control's internal control unit (MCU controller) is about to run out, requiring timely charging or battery replacement.
[0054] The aforementioned indicator lights can be implemented using light-emitting diodes (LEDs), which can be surface-mount (SMD) or through-hole (DIP) packages, and are mounted on the surface of the housing in a position that is easy to observe.
[0055] In some alternative embodiments, the indicator light can also use RGB full-color LEDs, reusing the same physical light position to achieve multiple status displays through color programming, thereby reducing the number of openings and structural complexity. In addition, a light guide or light shield can be added around the indicator light to enhance visibility and prevent misreading.
[0056] The switch assembly includes three main function switches: an emergency stop knob, a low-voltage switch, and a high-voltage switch. These switches are all mechanical electrical contact devices with a clear tactile feel and position locking function. The emergency stop knob is typically designed as a mushroom-shaped button that can only be reset after being rotated to unlock, meeting industrial safety standards and capable of quickly cutting off high-voltage circuits in emergencies. The low-voltage switch controls the on / off state of the low-voltage auxiliary system and is usually a self-locking tactile switch or toggle switch. The high-voltage switch authorizes the connection of the high-voltage main circuit and generally incorporates double confirmation logic to prevent accidental operation. Each switch is directly electrically connected to its corresponding indicator light via wires or PCB traces, and upon power-on, it drives the corresponding indicator light to operate according to its on / off state.
[0057] The emergency stop knob and the emergency stop status indicator are directly connected. When the knob is pressed, the contacts close, current flows through the emergency stop status indicator to light it up, and the signal is also sent to the MCU controller to trigger the wireless transmission module to send an emergency stop command to the race car.
[0058] Similarly, the low-voltage switch is connected to the low-voltage status indicator light. When the low-voltage switch is turned on, the low-voltage status indicator light illuminates, indicating that the system has completed its self-test and is in a low-voltage ready-to-start state. The high-voltage switch is connected to the high-voltage status indicator light. When the high-voltage switch is turned on, the high-voltage status indicator light illuminates, indicating that the race car's high-voltage power supply has been activated and it has entered the high-voltage start-up state. Although the battery warning status indicator light is not directly associated with any operating switch, it is controlled by the battery monitoring algorithm inside the MCU controller. When the battery voltage is detected to be lower than a preset threshold, the MCU outputs a pulse signal to drive the light to flash as an alarm.
[0059] In the above structure, multiple status indicator lights with specific functions and distinct colors are set up and directly electrically connected to the corresponding function switches, so that users can quickly identify the current system mode without relying on the display screen or other auxiliary tools.
[0060] For example, when the operator presses the power switch, if the blue low-voltage indicator light illuminates, it confirms that the race car has been powered on normally but has not yet entered the high-voltage operation stage; if the red high-voltage indicator light subsequently illuminates, it indicates that the high-voltage enable is successful and the race car is ready to drive; once the orange emergency stop indicator light illuminates, it immediately indicates that the safety circuit has been interrupted, and the cause must be investigated and manually reset; while the flashing yellow battery warning indicator light reminds the user to end the operation as soon as possible and charge the car to avoid the risk of loss of control due to MCU power failure. This not only improves the efficiency of human-machine interaction but also enhances the safety and fault tolerance of the remote control system.
[0061] Furthermore, in this embodiment, the low-voltage status indicator light illuminates in blue; the high-voltage status indicator light illuminates in red; the emergency stop status indicator light illuminates in orange; and the battery warning status indicator light illuminates and flashes in yellow. This embodiment achieves rapid visual recognition of the racing car remote control's operating status by configuring different functional status indicator lights with clearly semantically specific luminous colors. Addressing the problem of operator misjudgment caused by similar colors or a lack of unified coding logic in existing technologies, this embodiment employs a combination of color psychology and industrial design to establish an intuitive and efficient status visualization system.
[0062] The low-voltage status indicator light uses blue light to indicate that the race car is currently in a low-voltage, ready-to-start state. Blue, as a cool color, is commonly associated with standby, preparation, or pre-start states in human-machine interaction, effectively guiding the user to understand that the system has not yet entered a high-power operation phase. This indicator light can use an LED light source with a wavelength range of 460nm to 480nm to ensure good visibility in both sunlight and indoor lighting environments. In an optional embodiment, a blue-white dual-color LED can also be used, with brightness controlled by PWM dimming to meet visibility requirements in strong light environments.
[0063] The high-voltage status indicator light uses red light to indicate that the high-voltage switch has been turned on and the race car is in a high-voltage driving state. Red has the highest priority in visual warning systems and usually represents running, high energy, or prohibition of approach. It can quickly attract the operator's attention. The indicator light can use a high-brightness red LED with a peak wavelength of 620nm to 630nm and the light intensity stability can be ensured through a constant current drive circuit.
[0064] In an alternative embodiment, a slight flicker (such as a 1Hz low-frequency flicker) can be incorporated to enhance the dynamic alert effect, but it should be avoided to prevent confusion with fault alarm signals.
[0065] The emergency stop indicator light is orange, used to show that the emergency stop knob has been triggered, the race car's safety circuit has been disconnected, and emergency braking has been initiated. Orange, located between red and yellow, serves both as a warning and a transitional color, suitable for indicating emergency intervention or abnormal shutdown. Its wavelength is preferably in the 590nm–610nm range, which allows it to maintain sufficient penetration while distinguishing it from regular operating indicators.
[0066] In one variant, the orange LED can be linked with a buzzer to emit a short alert sound while the light is on, forming a multimodal alarm mechanism.
[0067] The low battery warning indicator light is yellow and operates in a flashing mode to alert the MCU controller or remote control that the power supply is low. Yellow, as a typical warning color, is widely used in low-energy warning scenarios in power systems. By setting periodic flashing (e.g., twice per second), it significantly improves attention capture and prevents static lights from being ignored in complex environments. The flashing frequency can be controlled by the MCU timer or dynamically adjusted by the C51 controller based on voltage data fed back from the battery management chip. In an optional embodiment, the flashing frequency increases gradually as the battery level decreases, achieving a match between the warning intensity and the risk level.
[0068] The above technical solution solves the technical problems of unclear status information transmission and easy misoperation in traditional remote controls, thereby improving human-computer interaction efficiency and operational safety. Especially in racing control scenarios that require rapid decision-making, it significantly reduces response latency and judgment error rate.
[0069] Furthermore, in this embodiment, the display component includes an OLED display screen, which is used to display the remaining power and attitude information of the MCU controller in real time. The OLED display screen is a self-emissive display device that does not require a backlight and has advantages such as high contrast, wide viewing angle, fast response, and low power consumption. It is suitable for information visualization display under various lighting environments. The OLED display screen is integrated into the remote control housing and interacts with the MCU controller through a communication interface (such as SPI or I²C) to dynamically refresh and present key operating status parameters.
[0070] Its display content mainly includes the remaining power of the MCU controller and the spatial attitude information of the remote control itself, thus providing operators with intuitive and accurate operation feedback.
[0071] The remaining battery power display is based on the mapping relationship between the battery open circuit voltage (OCV) and the state of charge (SOC). When the remote control is not in operation or in a static state, the battery management chip collects the battery terminal voltage, processes it through a voltage divider circuit, and sends it to the analog-to-digital converter (ADC) built into the MCU for digital sampling. The MCU then parses the current battery percentage according to the pre-stored OCV-SOC lookup table and presents the value in digital or graphical form on the OLED screen.
[0072] Furthermore, during charging, the C51 can acquire charging voltage and current data from the controller in real time and update the OLED display interface through a collaborative communication mechanism, enabling full monitoring of the charging status. The acquisition of attitude information relies on a built-in gyroscope sensor module, which connects to the MCU via the SPI communication protocol and continuously outputs three-axis angular velocity signals.
[0073] After the MCU reads the raw data from the gyroscope register, it performs unit conversion based on the device's calibrated range and sensitivity coefficients to obtain the actual angular velocity value. Then, an integral algorithm is used to accumulate the angular velocity data over time, calculating the remote control's rotation angles in the X, Y, and Z directions: pitch, roll, and yaw. These attitude parameters are ultimately displayed in real-time on the OLED screen in the form of numerical values, pointer graphs, or 3D model illustrations, helping users perceive changes in the remote control's spatial orientation.
[0074] The OLED display can be configured with different interface layout modes depending on the application scenario. For example, in the normal operation mode, the screen is divided into two areas: the upper area displays the remaining battery power in the form of a progress bar or percentage, and the lower area displays the attitude information in the form of a dynamic coordinate system or tilt indicator icon; in the debugging mode, you can switch to the advanced diagnostic interface by pressing a button to display more detailed sensor raw data, communication status and system operation logs.
[0075] As an alternative implementation, the OLED display can also be replaced with other types of active-matrix display devices, such as AMOLED or Micro LED displays, to meet the application requirements of higher brightness and higher resolution; or, without affecting visibility, a flexible OLED panel can be attached to the inside of a curved shell to improve the freedom of product industrial design.
[0076] The above technical solutions enable operators to quickly grasp the working status of the remote control in complex operating environments, improving the convenience and reliability of human-computer interaction. Especially in racing remote control scenarios that require precise control, the introduction of posture information helps to improve control accuracy and avoid control deviations caused by misjudging the hand direction. This effectively solves the problem of single information dimension and unintuitive feedback caused by traditional remote controls that rely solely on indicator lights or simple digital tube displays.
[0077] In this embodiment, the housing also includes a gyroscope and a battery charging system. The battery charging system includes a battery management chip, a C51 slave controller, and a USB expansion interface. The gyroscope, battery management chip, C51 slave controller, and USB expansion interface are connected to the display component.
[0078] By integrating a gyroscope and a complete battery charging management system within the remote control housing, the device's autonomous sensing capabilities and intelligent energy management level are enhanced. The gyroscope collects real-time attitude change data of the remote control, providing intuitive attitude feedback to the operator. The battery charging system, comprised of a battery management chip, a C51 slave controller, and a USB expansion interface, collectively monitors and controls the power supply and enables external interaction. The gyroscope connects to the MCU controller via an SPI communication interface, transmitting raw angular velocity signals to the MCU for processing before being sent to the display component. The signals are then visualized on an OLED screen, allowing users to track the remote control's real-time position in space. This design is particularly suitable for high-speed movement or complex control scenarios, improving the accuracy and responsiveness of human-computer interaction.
[0079] The battery management chip is responsible for real-time sampling and analysis of key parameters such as voltage, current, and temperature of the built-in lithium battery pack to prevent overcharging, over-discharging, short circuits, and high-temperature abnormalities, ensuring the safety and reliability of the charging process.
[0080] This chip typically uses a dedicated power management integrated circuit (such as the BQ series or MAX series) with multi-channel ADC acquisition capability, supports high-precision analog quantity detection, and can upload the acquisition results to the C51 slave controller via I²C or SPI bus. The C51 slave controller is a functional module independent of the main MCU, dedicated to performing tasks such as charging logic judgment, charging and discharging state switching, and fault alarm triggering. Based on the 8051 core architecture, it has the advantages of low power consumption, high stability, and a mature development ecosystem.
[0081] This controller not only receives data from the battery management chip but also dynamically adjusts the charging strategy using preset algorithms, such as reducing the charging current in low-temperature environments to protect battery life. Simultaneously, the C51 controller establishes a communication link with the display component, enabling real-time voltage, remaining battery percentage, and charging progress bar information to be displayed synchronously on the OLED screen, enhancing the user experience.
[0082] The USB expansion interface, as a physical layer access port, is compatible with the standard USB 2.0 protocol. It can be used to connect an external power adapter to power and charge the remote control battery, or to connect to a host computer for firmware upgrades, log export, or debugging information reading. This interface is connected to the C51 slave controller or master MCU through a level conversion chip to complete the mutual conversion between TTL / CMOS level and USB differential signal, ensuring communication compatibility.
[0083] In one alternative implementation, the USB expansion interface can be replaced with a Type-C interface to support reversible plugging and higher-power fast charging input; alternatively, a dual-interface solution can be configured, retaining the Micro-USB port as a backup maintenance port. Furthermore, this interface can also be expanded to connect external storage devices or wireless debugging modules, further enhancing the system's maintainability and functionality.
[0084] Through the above technical solutions, the remote controller is able to perceive its own motion state, thus providing data support for high-precision control. Simultaneously, the introduction of the battery charging system, especially the independent deployment of the C51 slave controller, eliminates the need for the main MCU to intervene in the cumbersome charging management process, effectively reducing the load on the main controller and improving the overall system stability and response speed. The multi-functional design of the USB expansion interface enhances the device's scalability and ease of maintenance. Therefore, it solves the problems of existing racing remote controllers, such as lack of self-testing capabilities, rudimentary charging management, and limited information feedback, significantly improving the product's intelligence level and safety. It is suitable for remote control scenarios of various high-performance electric Formula One race cars and can also be extended to other fields requiring high-reliability wireless control, such as drones and intelligent robots.
[0085] This implementation also includes a crystal oscillator, a power conversion module, a download module, and a level conversion chip, all of which are connected to the MCU controller.
[0086] Among them, the crystal oscillator, power conversion module, download module, and level conversion chip together provide a stable working environment and reliable program burning support for the MCU controller, thereby ensuring the normal operation and subsequent maintenance capabilities of the remote control electronic system. By configuring the above-mentioned peripheral auxiliary circuits, the stability of system operation can be improved, the convenience of development and debugging can be enhanced, and the electrical compatibility between different functional modules can be ensured, ultimately realizing a highly reliable and easy-to-maintain embedded control platform.
[0087] The crystal oscillator serves as the clock source, providing a precise and stable timing reference for the MCU controller and ensuring that its internal timers, communication interfaces (such as UART and SPI), and real-time task scheduling modules operate accurately at predetermined frequencies.
[0088] In practical implementation, an external quartz crystal resonator can be used in conjunction with a load capacitor to form a parallel resonant circuit, which is connected to the XTALIN and XTALOUT pins of the MCU. Typical operating frequencies can be selected from common industrial standard values such as 4MHz, 8MHz, or 16MHz. As a variant embodiment, a ceramic resonator can also be used to reduce costs, or an active crystal oscillator with integrated oscillation circuitry (such as an OSC package) can be used to improve anti-interference capability and startup speed.
[0089] The power conversion module is used to efficiently convert the input voltage from the battery (such as 12V DC voltage) into the operating voltage required by the MCU controller and other digital circuits (such as 3.3V or 5V). The module may include a DC-DC converter (such as a buck converter) and a low dropout linear regulator (LDO). The former has high energy conversion efficiency and is suitable for high current load scenarios; the latter has low output ripple and fast response, and is suitable for powering noise-sensitive analog or precision logic circuits.
[0090] In practical applications, voltage hierarchical management can be achieved through a multi-stage power architecture. For example, a DC-DC converter can first step down 12V to 5V, and then an LDO can regulate it to 3.3V for the MCU, thus balancing efficiency and stability. In addition, the power conversion module can also integrate overvoltage protection, overcurrent protection, and thermal shutdown functions to improve system safety.
[0091] The download module is used to flash firmware and debug the MCU controller online. It supports multiple standard debugging protocol interfaces, including SWD (Serial Wire Debug), JTAG (Joint Test Action Group), and UART-based bootloader.
[0092] The SWD interface requires only two signal lines (SWCLK and SWDIO), occupying fewer pins and making it suitable for designs with limited pin resources. JTAG supports more comprehensive debugging functions, such as multi-core debugging and boundary scan testing. The serial port download method eliminates the need for a dedicated debugger; basic firmware updates can be completed via host computer software combined with a bootloader program. This module is led out to the external housing or pre-reserved test points via pin headers or sockets, facilitating production testing and field upgrades. As an optional implementation, remote firmware upgrades (FOTA) can also be achieved wirelessly (such as LoRa or Bluetooth), further expanding maintenance flexibility.
[0093] Level conversion chips are used to solve signal compatibility issues between different voltage domains in a system. For example, between a USB expansion interface and an MCU, the 5V or 3.3V TTL / CMOS level in USB communication needs to be converted to a logic level acceptable to the MCU; or when the C51 slave controller communicates asynchronously with the master MCU, if their operating voltages are different (e.g., one is 5V and the other is 3.3V), a level conversion chip must be used to achieve bidirectional level matching.
[0094] Common solutions include using discrete resistors to build level clamping circuits, integrating dual-supply level shifters (such as TXS0108E, MAX3370, etc.), or MOSFET-based automatic direction-sensing level shifters. These chips can effectively prevent signal distortion or device damage caused by voltage mismatch, ensuring the reliability of cross-voltage domain communication.
[0095] The above technical solutions ensure the accuracy of the system clock and improve the synchronization performance of communication and control. The use of a power conversion module achieves efficient and stable voltage supply, extending battery life and improving system energy efficiency. The integrated download module makes firmware updates and troubleshooting more convenient, significantly lowering the barrier to later maintenance. The introduction of a level conversion chip solves the signal compatibility problem between multi-voltage systems, enhancing the robustness of the overall circuit. Therefore, the technical solution provided in this embodiment effectively solves the technical problem of MCUs struggling to operate stably for extended periods in complex electromagnetic environments and with diverse interfaces, achieving the technical effect of constructing a highly reliable, easy-to-develop, and easy-to-maintain racing car remote control control system.
[0096] In this embodiment, the integrated status monitoring module extends to the outside of the housing, ensuring good visibility of key status feedback components while protecting the internal electronic components. As a core component for users to obtain information about the remote control and race car's operating status, the partially exposed design of the integrated status monitoring module solves the problem of inconvenient information reading caused by traditional fully enclosed housings. By opening windows or reserving mounting positions in parts of the housing, key areas of the LED indicator group and display components are exposed to the external view, allowing real-time monitoring of the equipment status without disassembly or adjustment of the viewing angle during operation.
[0097] An integrated status monitoring module refers to an integrated electronic unit that integrates multiple status indication functions, including but not limited to LED indicator groups and display components (such as OLED screens), used to centrally display the remote control's own working status and communication feedback information with the race car.
[0098] This module typically consists of a PCB board, driving circuitry, light-emitting elements, and a display screen. Its overall layout employs a compact design to fit within the internal space of the remote control. In this embodiment, the module is not entirely housed within the casing; instead, its structural design allows at least a portion of its functional areas to extend beyond the casing boundaries. For example, the LED array and the front of the display screen are directly positioned at openings on the casing surface to allow light to pass through and images to be visible. This arrangement preserves the casing's protective function for the module's back and connecting circuitry while simultaneously improving the accessibility of the front-end human-machine interface.
[0099] As an optional embodiment, the integrated status monitoring module can be fixed to the front panel of the housing via an embedded installation method. A transparent protective cover is provided at the corresponding position on the panel. This cover can be made of polycarbonate (PC) or acrylic materials, possessing a certain degree of impact resistance and light transmittance, preventing dust and liquid intrusion while ensuring clear visibility of the lights. Furthermore, a waterproof sealing ring can be installed between the display screen and the housing to improve the overall structure's environmental adaptability, making it suitable for diverse outdoor usage scenarios.
[0100] Partial extension to the outside of the housing means that at least one functional surface of the module (such as the LED light-emitting surface or the screen display surface) is located on the outside of the housing, while the rest remains inside the housing and is electrically connected to the main control unit such as the MCU controller. This structure is not limited to a specific extension form; it can be a planar protrusion, a recessed embedding, or an inclined arrangement, as long as it allows the user to intuitively observe the status information in a normal holding posture. For example, the display component can be tilted at the top front of the housing, forming an elevation angle of approximately 15° to 30°, making it easy to look down; the LED indicator group is arranged linearly along the side of the housing to create a visual guidance effect.
[0101] The above technical solution enables users to quickly identify the current remote control's operating mode and the race car's response status under different lighting conditions and handheld angles, solving the problem of misjudgment or delayed reading of information caused by shell obstruction, thereby improving the safety and convenience of operation. At the same time, this design does not sacrifice overall protection performance; the internal core circuitry is still effectively isolated, balancing practicality, reliability, and industrial aesthetics.
[0102] In this embodiment, the wireless transmission module includes a LoRa module, an antenna, and a signal acquisition board. One end of the LoRa module is connected to the MCU controller, and the other end is connected to the signal acquisition board through the antenna.
[0103] Among them, the wireless transmission module is the core component for remote communication of the racing car remote controller. Its main function is to reliably send control commands and transmit racing car status information in real time. The module adopts the LoRa (Long Range Radio) technology architecture, which has long-distance transmission, low power consumption and strong anti-interference capabilities, and is suitable for high-speed mobile device communication scenarios in complex electromagnetic environments.
[0104] The LoRa module, acting as a modulation and demodulation unit, is electrically connected to the MCU controller via a UART or SPI interface on one end to receive digital control signals generated by the MCU, such as start / stop commands and mode switching commands. On the other end, it establishes a wireless connection with the signal acquisition board via an antenna through a radio frequency link, enabling bidirectional data interaction.
[0105] LoRa modules integrate an RF transceiver chip, a power amplifier (PA), a low-noise amplifier (LNA), and code error correction circuitry. They support spread spectrum modulation technology, which significantly improves communication distance and penetration while maintaining low power consumption. Typical operating frequency bands can be selected from 433MHz, 868MHz, or 915MHz ISM bands, depending on the actual application area.
[0106] When the MCU issues a control command, the LoRa module performs LoRa modulation processing, converts it into an RF signal with a specific bandwidth, spreading factor, and coding rate, and then outputs it to the antenna port after amplification by the internal PA.
[0107] The antenna, acting as a converter between electrical signals and electromagnetic waves, employs a high-gain omnidirectional antenna structure. It is mounted externally to the housing or integrated into the non-metallic area of the top of the housing, ensuring a wide angular coverage of the radiation pattern and preventing signal attenuation due to changes in the remote control's orientation. The antenna can connect to the LoRa module via an SMA or IPEX interface, ensuring good impedance matching and reducing signal reflection loss. In some optional embodiments, a dual-antenna diversity reception scheme can be used to further improve reception sensitivity and communication stability.
[0108] The signal acquisition board is located at the race car end and is used to receive downlink radio frequency signals from the remote controller and acquire local status parameters of the race car (such as motor speed, battery voltage, braking status, etc.). This information is then uploaded to the LoRa module at the remote controller end via the same wireless link. The signal acquisition board includes an RF front-end, an ADC acquisition unit, a microprocessor, and sensor interfaces, enabling simultaneous sampling and preprocessing of multiple analog and digital signals. It exchanges data with the LoRa module at the remote controller end through a preset communication protocol (such as a custom frame format + CRC check) to ensure data integrity and real-time performance.
[0109] It's important to note that the LoRa module and the signal acquisition board are not directly physically connected. Instead, they are wirelessly coupled and transmitted via an antenna. Therefore, the connection via antenna should be understood as follows: the radio frequency signal emitted by the LoRa module is radiated into space through the antenna, captured by the receiving antenna on the signal acquisition board, and sent to its internal LoRa receiving unit, thus establishing a logical communication link. The entire communication process supports half-duplex or full-duplex modes, depending on the specific hardware configuration.
[0110] The above technical solution enables an effective transmission distance of over 1000 meters in open outdoor environments. Even in track environments with obstacles, multipath interference, or strong electromagnetic noise, it can maintain a low bit error rate in data transmission. This not only ensures timely response to critical operations such as starting and stopping the race car, high-voltage power-on, and emergency braking, but also provides a continuous and accurate status feedback channel for the integrated status monitoring module, thereby improving overall control safety and user experience.
[0111] In a second aspect of the present invention, a Formula One race car is provided, which is remotely connected to a race car remote controller, which is the race car remote controller described above.
[0112] This Formula One car establishes a wireless communication connection with the aforementioned car remote controller, which has integrated status monitoring capabilities, forming a two-way interactive system for vehicle control collaboration. The car, acting as the actuator, receives control commands from the remote controller and feeds back its own operating status in real time. This enables remote perception and control of the vehicle's status, improving information transparency and responsiveness during car operation. It is particularly suitable for Formula E races or autonomous driving test scenarios requiring high-precision remote monitoring.
[0113] This Formula One car is equipped with a wireless receiver module compatible with the remote control. This module utilizes LoRa (Long Range) wireless communication technology, supporting stable data transmission even in complex electromagnetic environments, with a communication range exceeding 1000 meters. The LoRa module operates in ISM unlicensed frequency bands (such as 433MHz or 868MHz), possessing strong anti-interference capabilities and low power consumption, ensuring a continuous and reliable data link between the car and the remote control during high-speed movement. The wireless receiver module includes an RF front-end circuit, a signal demodulation unit, and a microcontroller interface. It receives coded control signals sent by the remote control and parses them into commands recognizable by the car's electronic control system, such as start, brake, high-voltage power-on, and emergency stop.
[0114] The Formula One car also features a status feedback unit to collect the car's operating parameters and transmit them back to the remote controller. This status feedback unit includes, but is not limited to, a motor controller (MCU), a battery management system (BMS), a gyroscope sensor, a braking status detection circuit, and a voltage and current sampling module. These sensors and control units are connected to the main control chip in the wireless receiver module via a CAN bus or UART serial interface. They periodically package key information such as the car's current attitude angle, remaining battery power, bus voltage, drive status, and safety circuit on / off status into data frames, which are then transmitted back to the remote controller via the LoRa module.
[0115] Specifically, the Formula One car's status feedback mechanism forms a closed-loop linkage with the integrated status monitoring module on the remote controller: when the car is in low-voltage standby mode, its BMS reports a low-voltage preparation signal to the remote controller, triggering the blue low-voltage status indicator light on the remote controller to illuminate; when the high-voltage relay closes and the vehicle enters the driving preparation state, the car reports a high-voltage enable signal, and the red high-voltage status indicator light on the remote controller illuminates accordingly; once the emergency stop button is triggered or the safety circuit is disconnected, the car immediately sends an emergency braking flag, and the orange emergency stop status indicator light on the remote controller responds instantly and remains constantly lit; when the car's power battery voltage is lower than a set threshold, the system automatically uploads a low-battery alarm, and the yellow battery warning light on the remote controller begins to flash.
[0116] In addition, the Formula One car's communication protocol uses a lightweight data encapsulation format. Each data packet contains a frame header, device ID, command word, data field, checksum, and frame trailer, ensuring data integrity and error prevention capabilities. The communication between the remote controller and the car supports a two-way authentication mechanism to prevent unauthorized devices from accessing the control system, thereby improving the overall system's security and reliability.
[0117] Through the above technical solution, operators can monitor the running status of the Formula One car in real time and apply precise control without close human contact. Because the car actively uploads multi-dimensional status information and presents it in a visual way (including LED light status and OLED screen data display), it effectively solves the problems of traditional remote control systems that only transmit and do not receive, and status blind spots. It significantly enhances the controllability, debugging efficiency and emergency response capability of the whole vehicle system. Especially in high-intensity competition or field testing environments, this remote two-way communication architecture provides important decision-making basis for drivers or engineering teams and improves the overall safety margin of operation.
[0118] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
