Description

Technical Field

[0001] The present invention relates to the field of motorcycle instrument adjustment systems, and particularly to a method for automatically adapting the motorcycle instrument to the user's perspective based on infrared sensing. Background Art

[0002] Motorcycles, as a convenient means of transportation, have a large market share in the transportation field. They are not only used for personal travel and cargo transportation, but also commonly used for reconnaissance, patrol, and transportation tasks in the military and police departments. Motorcycles can also be used as sports and entertainment tools, and many people like to ride motorcycles for off-road, travel, or participate in races. As the human-machine interaction window of a motorcycle, the instrument is crucial for riders, such as displaying driving information, vehicle operating state parameters, and fault alarm prompts.

[0003] In the design of motorcycles, as an important component for transmitting key vehicle information to riders, whether the instrument content can be observed intuitively and clearly will directly affect the riding experience and driving safety. Traditional motorcycle instruments are usually fixed on the instrument panel, and the display surface may not be consistent with the driver's line of sight. Especially when the driver's height, body type, or driving habit changes, this problem will be more prominent, which will not only affect the driver's comfort, but may also pose a safety hazard.

[0004] Defects and deficiencies of the prior art:

[0005] 1. The instruments are all designed with fixed positions: Currently, when designing motorcycles, most instruments are fixed to the front of the vehicle head at a certain position and angle, and once fixed, they cannot be moved and adjusted later. Due to the height differences of different riders, the viewing angles of the instruments are different, and the best viewing angle cannot be obtained.

[0006] 2. Inconvenient operation: The existing solutions mainly involve manually adjusting the position of the instrument to adapt to the driver's line of sight. This method requires the driver to make adjustments before driving, which is inconvenient to operate and cannot adapt to the driver's dynamic changes in real time. In addition, some high-end motorcycles are equipped with electric adjustment functions, but usually manual adjustment is performed through buttons or knobs, and there is still the problem of inconvenient operation.

[0007] 3. Lack of intelligence and automation: First, the method of manually adjusting the instrument position is time-consuming and laborious, and it is difficult to make dynamic adjustments during driving. Second, although the existing electric adjustment functions can achieve a certain degree of automation, the adjustment process requires manual operation by the driver and cannot achieve true intelligence and automation.

[0008] 4. Unable to adapt to the dynamic changes of the driver in real time: The existing technologies have obvious deficiencies in adapting to the personalized needs of the driver. None of these methods take into account that the driver's line of sight is affected by the movement of the head, so they cannot accurately reflect the actual needs of the driver. Summary of the Invention

[0009] In view of the above deficiencies in the prior art, the present invention provides a method for automatically adjusting the motorcycle instrument's viewing angle based on infrared sensing to adapt to different drivers' heights, body types, and driving habits, thereby improving the driving experience and safety of the driver.

[0010] To achieve the above object, the present invention adopts the following technical solutions:

[0011] A method for automatically adjusting the motorcycle instrument's viewing angle based on infrared sensing, characterized by comprising the following steps:

[0012] S1. Through the infrared sensor provided on the motorcycle, the head position or line of sight direction of the driver is detected in real time, and the detection result is input into the control unit as an electrical signal.

[0013] S2. The control unit performs calculation and processing based on the electrical signal transmitted by the infrared sensor, and obtains the corresponding tilt angle of the instrument assembly according to the driver's line of sight direction.

[0014] S3. The control unit compares the calculated tilt angle of the instrument assembly with the current instrument state. If the angle deviation is less than 5°, no adjustment is made. If the angle deviation is greater than 5°, a control signal is output to the instrument angle adjustment mechanism.

[0015] S4. The instrument angle adjustment mechanism accurately adjusts the instrument to the predetermined angle according to the control signal output by the control unit, so that the display surface of the instrument always remains at the best viewing angle of the driver.

[0016] Further, the infrared sensor is provided at the top of the instrument assembly, and the processing circuit of the infrared sensor is integrated into the instrument assembly circuit.

[0017] Further, the infrared sensor detects the head position or line of sight direction of the driver once per second.

[0018] Further, the instrument angle adjustment mechanism includes an instrument screen, an instrument lower housing, a support rod, a base, and a base upper cover. The instrument screen is arranged on the instrument lower housing. One end of the instrument lower housing is hinged to the base upper cover. The upper end of the support rod is hinged to the other end of the instrument lower housing, and a jacking mechanism is connected to the lower end of the support rod.

[0019] Further, the jacking mechanism includes a motor, an output pulley, a driven shaft, a driven pulley, and a slider. The motor is disposed on the base. The driven shaft is disposed on the base through a bearing. The output pulley is disposed on the output shaft of the motor. The driven pulley is disposed on the driven shaft. The output pulley and the driven pulley are driven by a belt. The slider and the driven shaft are driven by a lead screw-nut structure. The lower end of the support rod is hinged to the slider.

[0020] Further, the base cover is disposed on the base through fixing screws. The bottom of the base is provided with base fixing bolts, and buffer rubber is provided on the base fixing bolts.

[0021] Further, a controller corresponding to the left and right extreme positions of the slider is disposed on the base, and the controller controls the motor to stop.

[0022] The beneficial effects of the present invention include: high degree of intelligence and automation, real-time detection of the driver's head position or line of sight direction, and automatic adjustment of the inclination angle of the instrument assembly according to the electrical signal, so that the display surface of the instrument always remains at the best viewing position of the driver, 3.

[0027] The present invention will be further described in detail below in conjunction with specific embodiments and the accompanying drawings.

[0028] A motorcycle instrument self-adaptive user perspective adjustment method based on infrared sensing as Figures 1-4 shown, this solution uses infrared sensor technology to achieve automatic adjustment of the instrument perspective to adapt to the heights, body types and driving habits of different drivers, thereby improving the driving experience and safety of the drivers.

[0029] The specific implementation steps are as follows:

[0030] S1. An infrared sensor installed on the motorcycle is used to detect the position of the driver's head or the direction of the line of sight in real time, and the detection result is input into the control unit as an electrical signal. The infrared sensor is integrated inside the instrument and arranged at the top of the instrument, making an integrated whole with the instrument assembly. This integrated way facilitates installation and layout as well as the management of the component status. The infrared signal processing circuit can share the circuit of the instrument assembly to save costs. This position is in front of the driver's head and can detect the position of the driver's head or the direction of the line of sight in real time. The infrared sensor uses a high-precision infrared sensor that can penetrate obstacles, is not affected by light, and can work stably under various environmental conditions.

[0031] S2. The control unit performs calculation and processing based on the electrical signal transmitted by the infrared sensor, and obtains the corresponding tilt angle of the instrument assembly according to the direction of the driver's line of sight. It mainly relies on the pyroelectric effect and the function of the Fresnel lens to determine the position of the human body in space by sensing the infrared radiation emitted by the human body. It can judge the relative orientation of an object, such as distance, shape and size, and capture the dynamic information of the object, such as motion state, speed and direction. After being irradiated by this infrared radiation, the pyroelectric sensor will produce a pyroelectric effect, that is, a voltage change. By analyzing the intensity and direction of the infrared radiation emitted by the human body, the head position and the line of sight direction are judged. The signal processing part is responsible for processing the electrical signal output by the detector and finally converting it into data that can represent the human activity and position. The infrared sensor detects the position of a person by detecting the infrared radiation emitted by the human body. The infrared sensor detects the position of the driver's head or the direction of the line of sight once per second and transmits the detected electrical signal to the control unit. The computing power of the control unit is 10 times per second, and it can respond to the dynamic changes of the driver in real time.

[0032] S3. The control unit compares the tilt angle of the instrument assembly obtained by calculation with the current instrument state. The control unit uses an advanced software algorithm to make judgment and processing based on the electrical signal transmitted by the infrared sensor. If the position of the driver's head or the direction of the line of sight has been in a constantly moving state, no control adjustment is made. When the detection signal is almost in a stable state, the adjustment angle is calculated. If the angle deviation is less than 5°, no adjustment is made. If the angle deviation is greater than 5°, a control signal is output to the instrument angle adjustment mechanism.

[0033] S4. The instrument angle adjustment mechanism accurately adjusts the instrument to the predetermined angle according to the control signal output by the control unit. The angle adjustment mechanism uses high-precision sensors and control algorithms to accurately adjust the tilt angle of the instrument assembly, so that the display surface of the instrument always remains at the best viewing angle of the driver.

[0034] Such as Figures 2-4, the instrument angle adjustment mechanism includes an instrument screen 1, an instrument lower housing 2, a support rod 3, a base 6, and a base upper cover 4. The instrument screen 1 is arranged on the instrument lower housing 2. The base upper cover 4 is arranged on the base 6 through fixing screws. A base fixing bolt 8 is arranged at the bottom of the base 6, and a buffer rubber 7 is arranged on the base fixing bolt 8. One end of the instrument lower housing 2 is hinged to the base upper cover 4, the upper end of the support rod 3 is hinged to the other end of the instrument lower housing 2, and a jacking mechanism is connected to the lower end of the support rod 3.

[0035] The jacking mechanism includes a motor 19, an output pulley 20, a driven shaft 12, a driven pulley 11, and a slider 15. The motor 19 is arranged on the base 6. The driven shaft 12 is arranged on the base 6 through a bearing 9. The output pulley 20 is arranged on the output shaft of the motor 19. The driven pulley 11 is arranged on the driven shaft 12. The output pulley 20 and the driven pulley 11 are driven by a belt 10. The slider 15 and the driven shaft 12 are driven by a lead screw nut structure. The lower end of the support rod 3 is hinged to the slider 15.

[0036] A controller 16 corresponding to the left and right extreme positions of the slider 15 is arranged on the base 6. The controller 16 controls the motor 19 to stop. During the entire movement process, the instrument screen can generate an adjustment angle of 20° around the rotation point.

The descriptions of the above embodiments are only applicable to help understand the principles of the embodiments of the present invention.
