Description

Technical Field

[0001] This invention relates to the field of vehicle technology, and in particular to a method for calculating the opening degree of a vehicle window. Background Technology

[0002] Opening and closing car windows are frequently used functions during vehicle operation. The degree of window opening affects interior comfort, airflow, temperature, and the operation of air conditioning, seat heating, and even vehicle safety. Current window switches lack feedback on window opening information, relying on Hall effect motors to identify the window's position. However, ordinary motors in vehicles typically lack Hall effect signals and cannot provide feedback on window opening. As vehicles evolve towards intelligence, recognizing whether windows are closed and their opening status is crucial for enabling intelligent functions such as comfortable temperature adjustments for air conditioning, intelligent control of seat heating, intelligent recognition and interaction of window openings throughout the vehicle, and reminders to close windows when parking or during rain.

[0003] A Chinese invention patent with publication number CN114531068A discloses a method for determining the opening degree of a vehicle window, applicable to a vehicle. The vehicle includes a window drive motor. The method includes: receiving a ripple signal generated by the window drive motor; obtaining the current operating condition of the window drive motor; determining a target ripple processing strategy corresponding to the current operating condition from multiple ripple processing strategies; processing the ripple signal according to the target ripple processing strategy to obtain window state parameters corresponding to the ripple signal; and determining the opening degree of the vehicle window according to the window state parameters.

[0004] The aforementioned patent determines a target ripple processing strategy for processing the ripple signal under the current operating condition of the window drive motor. This target ripple processing strategy is then used to process the ripple signal under the current operating condition, thereby obtaining accurate window status parameters. Window opening is determined using a ripple-based method, which requires hardware identification and processing of the ripple in the circuitry. This high hardware requirement makes this method difficult to popularize and apply to conventional window operation. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art by providing a method for calculating the opening degree of a vehicle window. This method can meet the requirements of intelligent vehicles to recognize the current opening degree of the window, requires no special hardware of the vehicle, is calculated by software, requires minimal modification to the vehicle system, has low cost, and can improve the comfort and control of the vehicle.

[0006] The technical solution of this invention: a method for calculating the opening degree of a vehicle window, including the calculation of the amount of opening action and the calculation of the opening degree.

[0007] The formula for calculating the motion openness measure is: Motion openness measure = Td*Uw / 14 / Tadn*(1+C1*Nd)-Tu*Uw / 14 / Taun*(1+C2*Nu),

[0008] in,

[0009] C1 and C2 are adjustment coefficients, with C1 ranging from 0 to 0.04 and C2 ranging from 0.003 to 0.007.

[0010] Td is the descent time, Uw is the operating voltage, Tadn is the time for the window to fully close, Nd is the number of descent movements, Tu is the rise time, Taun is the time for the window to fully rise, and Nu is the number of rise movements.

[0011] The formula for calculating the opening degree is: Opening degree = (Original opening degree value ± Action opening degree) * 100 / 10;

[0012] When the car window is in the rolled-up position

[0013] Opening degree = (original opening degree value - action opening degree) * 100 / 10 and round down to the nearest integer.

[0014] When the car window is down

[0015] Opening degree = (original opening degree value + action opening degree) * 100 / 10 and round down to the nearest integer.

[0016] in,

[0017] The original opening value is a percentage value, representing the percentage of the original window opening, and is set to [0%, 100%]. The action opening value is a percentage value, representing the proportion of the window action distance in the entire window during this operation, and is set to [0%, 100%]. The opening value is the calculation result, reflecting the evaluation result of the window opening size, and is set to [0%, 100%].

[0018] Using the above technical solution, this method does not require a Hall motor, has no ripple recognition requirements, and adds no cost to the original window system hardware. It calculates the five main opening degrees through software. This calculation method can adapt to different motors and window characteristics. Using ordinary motors without Hall information and ripple-free window switches with software control and communication functions, the window opening degree calculation method mentioned in this patent can determine the current window opening degree, which can meet the requirements of intelligent vehicles to recognize the current window opening degree. This calculation method has no special requirements for the vehicle hardware, is calculated by software, requires minimal modification to the vehicle system, and has low cost. Introducing this method into the vehicle can improve the comfort and control of the vehicle.

[0019] A further setting of the present invention: Initially, Tadn and Taun are both set to N.

[0020] When fully opening or closing all windows, correct Tadn and Taun after the vehicle is in position and stalls.

[0021] Preferably, Tadn and Taun are initially set to 10.

[0022] The above further settings are applicable to various types of vehicles. Since the window sizes of different vehicle types are not the same, first set the values ​​of Tadn and Taun to N, then fully open or fully close the window once to make corrections and adjust the values ​​of Tadn and Taun to match the window size of the vehicle. Attached Figure Description

[0023] Figure 1 This is a logic block diagram of the calculation method according to a specific embodiment of the present invention. Detailed Implementation

[0024] The technical solutions in this embodiment 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. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] like Figure 1 As shown, a method for calculating the opening degree of a vehicle window includes calculating the amount of opening action and calculating the opening degree.

[0026] The formula for calculating the motion openness measure is: Motion openness measure = Td*Uw / 14 / Tadn*(1+C1*Nd)-Tu*Uw / 14 / Taun*(1+C2*Nu),

[0027] in,

[0028] C1 and C2 are adjustment coefficients. C1 ranges from 0 to 0.04, and C2 ranges from 0.003 to 0.007. C1 can be 0.1, 0.02, 0.03, or 0.15, 0.25, etc., with a preferred value of 0.02. C2 can be 0.003, 0.004, 0.005, 0.006, or 0.007, with a preferred value of 0.005.

[0029] Td is the descent time, Uw is the operating voltage, Tadn is the time for the window to fully close, Nd is the number of descent movements, Tu is the rise time, Taun is the time for the window to fully rise, and Nu is the number of rise movements.

[0030] The formula for calculating the opening degree is: Opening degree = (Original opening degree value ± Action opening degree) * 100 / 10;

[0031] When the car window is in the rolled-up position

[0032] Opening degree = (original opening degree value - action opening degree) * 100 / 10 and round down to the nearest integer.

[0033] When the car window is down

[0034] Opening degree = (original opening degree value + action opening degree) * 100 / 10 and round down to the nearest integer.

[0035] in,

[0036] The original opening value is a percentage value, representing the percentage of the original window opening, taken as [0%, 100%]. The action opening value is a percentage value, representing the proportion of the window's movement distance in the entire window, taken as [0%, 100%]. The opening value is the calculated result, reflecting the assessment result of the window's opening size, taken as [0%, 100%]. An opening value of 0% indicates that the window is not open; 0-20% is a small gap; 20-30% is a large gap; 30-50% is a medium window; 50-90% is a large window; and 100% is fully open. When calculating the opening next time, the previous opening value is used as the original opening value for the next calculation. This method does not require... The system requires Hall effect motors with no ripple recognition requirements, incurring no additional cost to the original window system hardware. The calculation of five main opening degrees is achieved through software. This calculation method is adaptable to different motors and window characteristics. Using ordinary motors without Hall effect information and ripple-free window switches with software control and communication functions, the current window opening can be determined using the window opening calculation method mentioned in this patent. This meets the requirements of intelligent vehicles for recognizing the current window opening. This calculation method has no special requirements for the vehicle's hardware, is calculated by software, requires minimal modification to the vehicle system, and is low-cost. Introducing this method into the vehicle can improve the level of comfort and control.

[0037] Initially, Tadn and Taun are both set to N.

[0038] When fully opening or closing a car window, adjust Tadn and Taun after the window is fully locked. This applies to various types of vehicles, as the window sizes of different vehicle types are not the same. First, set the value of Tadn and Taun to N, for example, 10s. Then, perform a full opening or full closing of the window and make corrections by adjusting the values ​​of Tadn and Taun. The adjusted values ​​can be 8s, 12s, etc. Adjust the time for fully lowering and raising the window according to the window size of each vehicle to make it suitable for the vehicle's window size.
