Description

Technical Field

[0001] This application relates to the field of gaming devices, and more particularly to a decoupling mechanism, method and related apparatus for a vehicle steering wheel. Background Technology

[0002] With the continuous development of the gaming industry and the increasing market demand, gaming devices, as an important carrier of interactive entertainment, are constantly improving in terms of technology and user experience. To meet players' pursuit of realism and immersion in games, various gaming devices are emerging, with racing steering wheels being one of the most popular gaming peripherals.

[0003] Existing racing steering wheels primarily control the car by mechanically connecting the steering wheel to a mechanical steering mechanism, directly controlling the steering wheel's rotation angle. This design simulates the operation of real driving, enhancing the game's realism and immersion, and has been well-received by many racing game enthusiasts.

[0004] However, in racing games, players typically need to use both hands and feet to perform actions such as accelerating, braking, and shifting gears. During gameplay, players sometimes need to access game menus, such as adjusting the camera angle or pausing the game. However, existing racing steering wheel designs do not adequately address this need, forcing players to remove their hands from the steering wheel and use a gamepad. This control method not only affects the smoothness of the game but also makes players more prone to mistakes during tense and exciting races, thus diminishing the gaming experience.

As part of this specification, some of the accompanying drawings of this disclosure are block diagrams illustrating structures and devices to avoid complicating the disclosed principles. For clarity, not all features of the actual embodiment need to be described.

Therefore, the use of the terms “a” or “an” can mean any number of at least one, including “a,” “one or more,” “at least one,” and “one or more.” The term “or” means any of the options and any combination of the options, including all options unless explicitly indicated that the options are mutually exclusive. The phrase “at least one of” when combined with a list of items refers to a single item in the list or any combination of items in the list. The phrase does not require all items listed unless explicitly defined as such.

[0044] Reference Figure 1 The vehicle steering wheel decoupling mechanism includes an angle detection device 1, a control device 2, a drive device 3, and a reset device 4. The angle detection device 1 acquires the rotation angle information of the steering wheel 5 and sends it to the control device 2. Based on the current decoupling status, the control device 2 decides whether to send the rotation angle information to the drive device 3. The drive device 3 can control the input shaft of the steer-by-wire mechanism 6 based on the received information to adjust the forward direction of the car in the game.

[0045] Specifically, the central axis of the steering wheel 5 is stationary relative to the frame. In different embodiments, the frame may be provided with an extended bracket for the steering wheel 5 to pass through and be rotatably connected to it. The shape of this bracket is not specifically limited in this application. For example, the bracket may have a U-shaped design, with the steering wheel 5 passing through both sides of the bracket and fixed inside it; or, the bracket may have a ring-shaped design, with the steering wheel 5 placed inside the ring-shaped bracket and rotatably connected to it. It should be noted that the frame... Figure 1The fact that the steering wheel 5 and its shaft are not shown does not mean that the steering wheel 5 and its shaft are suspended in the air, nor does it mean that the control device 2, drive device 3, steering mechanism 6 and reset device 4 are suspended in the air.

[0046] An angle adjustment device is typically used to detect, adjust, or control the angle of a rotating object. Angle detection device 1 is connected to steering wheel 5 and detects the rotation angle information of steering wheel 5. Depending on the type of angle sensor, the angle sensor can be fixed relative to the aforementioned bracket or can rotate relative to steering wheel 5.

[0047] Here are some examples of available angle adjustment devices:

[0048] Rotary Encoder: A rotary encoder is a common angle sensor that can detect the rotation angle and speed of an object. It can be absolute or incremental. For example, a rotary encoder can be mounted on the shaft of a steering wheel 5. When the steering wheel 5 is rotated, the rotary encoder will output pulse signals representing the angle change and direction. These pulse signals can be decoded by a microcontroller or other processor to obtain the real-time rotation angle and direction of the steering wheel 5.

[0049] Gyroscope: A gyroscope is a sensor that uses the principle of angular momentum to measure and maintain orientation, used to detect and adjust the angle and attitude of an object. For example, if a gyroscope is mounted on a steering wheel 5, it will detect the rotational angular velocity when the steering wheel 5 is rotated. By integrating the gyroscope signal, the real-time rotation angle and direction of the steering wheel 5 can be obtained.

[0050] Potentiometer: A potentiometer is a variable resistor that changes its resistance by rotating its shaft, thereby detecting the rotation angle of an object. For example, the rotation shaft of the potentiometer can be connected to the shaft of the steering wheel 5. When the steering wheel 5 is rotated, the resistance value of the potentiometer will change accordingly. The direction and angle of rotation of the steering wheel 5 can be determined by measuring the voltage signal from the potentiometer.

[0051] Magnetic Sensor: A magnetic sensor can detect changes in magnetic field strength, thereby measuring the rotation angle of an object. For example, a magnetic sensor (such as a Hall effect sensor) can be installed near the shaft of the steering wheel 5, with a magnetic element mounted on the shaft. When the steering wheel 5 rotates, the change in the magnetic field will be detected by the magnetic sensor. Based on the direction and magnitude of the change in the magnetic field, the direction and angle of rotation of the steering wheel 5 can be determined.

[0052] Optical encoders use photoelectric sensors to detect changes in a grating pattern, thereby measuring the rotation angle of an object. Optical encoders are used in high-precision angle measurement, servo motor control, and other applications. For example, an optical encoder can be mounted on the 5-axis of a steering wheel, with a grating pattern set on the axis. When the steering wheel 5 rotates, the changes in the grating pattern will be detected by the photoelectric sensor. Based on the changes in the photoelectric signal, the rotation direction and angle of the steering wheel 5 can be determined.

[0053] Control device 2 is communicatively connected to angle detection device 1 to receive rotation angle information and split control information. In different embodiments, control device 2 can be selected according to actual application needs and performance requirements. In actual systems, these control devices 2 can be combined with corresponding communication interfaces and angle detection devices 1 to achieve effective control of the decoupling mechanism of steering wheel 5.

[0054] Here are some examples of control device 2:

[0055] Microcontroller: A microcontroller is a single-chip integrated circuit that integrates a processor, memory, and peripheral interfaces. Common microcontrollers include Arduino, PIC, AVR, and STM32. The microcontroller can be used to process signals from the angle detection device 1 and output drive control signals according to the algorithm.

[0056] Single-board computer: A single-board computer is a small computer that integrates a processor, memory, storage, and various interfaces, such as the Raspberry Pi and BeagleBone. Single-board computers have strong processing capabilities and can run complex control algorithms and communication protocols.

[0057] Programmable Logic Controller (PLC): A PLC is an industrial control system designed for automated control. PLCs possess powerful input / output processing capabilities and real-time control functions, making them suitable for various industrial environments.

[0058] Digital Signal Processor (DSP): A DSP is a processor specifically designed for high-speed signal processing tasks. A DSP can perform real-time processing and filtering of signals from the angle detection device 1, improving the response speed and accuracy of the control system.

[0059] Field-Programmable Gate Array (FPGA): An FPGA is a programmable logic circuit that can implement various digital circuit functions according to user requirements. FPGAs have highly parallel computing capabilities and are suitable for high-speed, real-time control tasks.

[0060] In different embodiments, the control device 2 and the angle detection device 1 can communicate in different ways. The following is an example of a wired communication connection:

[0061] I2C (Inter-Integrated Circuit): I2C is a two-wire serial bus used to connect low-speed peripheral devices, such as microcontrollers and sensors. Through the I2C bus, control device 2 can communicate bidirectionally with angle detection device 1, receiving rotation angle information and split control information.

[0062] SPI (Serial Peripheral Interface): SPI is a high-speed synchronous serial communication interface used to connect microcontrollers and external devices. SPI communication uses four wires for data transmission and can achieve full-duplex communication between control device 2 and angle detection device 1.

[0063] UART (Universal Asynchronous Receiver / Transmitter): UART is an asynchronous serial communication interface that enables bidirectional data transmission between control device 2 and angle detection device 1. UART communication uses two wires for sending and receiving, resulting in low hardware overhead.

[0064] CAN (Controller Area Network): The CAN bus is a multi-master communication protocol used for real-time control and is widely used in automotive electronic systems. Through the CAN bus, control device 2 can reliably communicate with angle detection device 1.

[0065] Control device 2 converts instantaneous angle control information into a continuous drive control signal based on the split control information. The split control information can be a signal based on the on / off state of a push-button switch, such as a split toggle switch on the steering wheel 5, where turning it to one side indicates splitting and turning it to the other side indicates joining, corresponding to the split control information and joining control information. In another embodiment, it can also be based on detecting the separation and joining of the steering wheel 5 and the pivot shaft. Specifically, after receiving the rotation angle information and the split control information, control device 2 can use a PID (proportional-integral-derivative) control algorithm to calculate the continuous drive control signal. By adjusting the parameters of the PID controller, precise control of the output torque of the drive device 3 is achieved, ensuring that the input shaft of the steer-by-wire mechanism 6 is synchronized with the rotation angle of the steering wheel 5.

[0066] The drive unit 3 is separate from the steering wheel 5 and communicatively connected to the control unit 2. It receives continuous drive control signals and controls the rotation of the input shaft of the steer-by-wire mechanism 6 based on these signals. Here, the drive unit 3 drives the steer-by-wire mechanism 6; that is, the steering mechanism 6 is separate from the steering wheel 5 and there is no direct or indirect mechanical transmission relationship between them. The rotational transmission between them is accomplished through electrical signals.

[0067] A conventional mechanical steering mechanism 6 primarily achieves steering control between the steering wheel 5 input and the wheels through a series of mechanical connecting parts. The following are the main components of a conventional mechanical steering mechanism 6:

[0068] Steering wheel 5: The driver controls the vehicle's steering by operating steering wheel 5.

[0069] Steering shaft: Transmits the rotation of steering wheel 5 to steering gearbox. It usually consists of a long shaft and a short shaft, connected by a universal joint or other coupling.

[0070] Steering gearbox: Converts the rotational motion of the steering wheel 5 into linear motion to drive the wheels in steering. Common types of steering gearboxes include worm gear type and rack and pinion type.

[0071] Steering linkage: Transmits the linear motion generated by the steering gearbox to the steering knuckle, causing the wheels to steer.

[0072] Steering knuckle: A component that connects the wheel and the steering linkage, enabling the wheel to rotate in the horizontal direction.

[0073] In a conventional mechanical transmission steering mechanism 6, the rotation of the steering wheel 5 goes through a series of mechanical transmission links to ultimately achieve steering control of the wheels.

[0074] In this solution, the physical connection between the steering wheel 5 input and the vehicle steering system is replaced by electronic signal transmission. Vehicle steering control is achieved through electronic sensors and actuators, rather than relying on traditional mechanical connections. For example, the control device 2 (e.g., a microcontroller) detects the rotation angle of the steering wheel 5 via the angle detection device 1. Based on the received rotation angle information and the split control information, the control device 2 calculates a continuous drive control signal (e.g., a pulse width modulation signal, PWM signal). This signal is sent to a servo motor communicatively connected to the control device 2. The servo motor adjusts its speed and steering according to the received PWM signal, thereby controlling the rotation of the input shaft of the steer-by-wire mechanism 6.

[0075] It is important to note that when the split control information is issued, the control device 2 acquires the instantaneous angle control information corresponding to the moment the split control information is issued, and continuously issues drive control signals based on this instantaneous angle control information until the control device 2 acquires the combined control information. In other words, after the split control information is issued, the drive device 3 locks, meaning the direction of the vehicle steering system is locked.

[0076] When control device 2 receives the combination control information, it sends a reset rotation information to reset device 4 based on the combination control information and the continuous drive control signal. Reset device 4 is connected to steering wheel 5 and controls steering wheel 5 to rotate and reset based on the reset rotation information. Similar to drive device 3, reset device 4 is used to drive steering wheel 5 to rotate, and it mechanically transmits power to the steering wheel 5's shaft. That is, when steering wheel 5 no longer functions as a handle but reverts to its original steering wheel function, it communicates with control device 2 to trigger angle reset, causing steering wheel 5 to rotate to an angle matching the tire angle. This design automatically matches the steering wheel 5 and tire position when exiting the game, facilitating user switching between game and real-world driving and improving the device's usability.
