Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vehicle window control, and in particular to a commercial vehicle window stall current active calibration method and system. BACKGROUND

[0002] With the rapid development of the domestic commercial vehicle technology field, the traditional energy and new energy commercial vehicle ownership increases rapidly, and the electrification level of commercial vehicles has also made great progress. The comfort level of the body accessories is also increasing. In the commercial vehicle market, the traditional commercial vehicle window basically adopts manual control, does not have the functions of electric control, automatic lifting and anti-pinch of the window, and does not have the electronic devices of the window motor and the window controller. Therefore, there is no high technical requirement for the window motor, which reduces the cost and ensures the electrical function, and becomes the general practice in the current commercial vehicle field.

[0003] However, there is no position sensor and anti-pinch sensor in the electric control scheme of the commercial vehicle window, and the stall phenomenon of the window motor occurs when the window is lifted to the highest point or lowered to the lowest point, so that the stall current at that time is detected to determine whether the window reaches the limit position, and the window motor is controlled to stop. Due to the consistency problem of the electrical properties of the window motor (the output power is not consistent under the rated voltage), the weight of the window and the movement resistance of the window also have great differences, which leads to great differences in the stall calibration current of each window. Manual detection and manual calibration of each window will cause a lot of time and labor cost waste. If the window motor works in the stall current state for a long time, there will be a risk of fire due to circuit short circuit. If the window motor has an overcurrent protection function, the window will vibrate due to frequent motor starting. SUMMARY

[0054] Embodiment 1

[0055] Reference Figures 1-3 For the first embodiment of the present application, the embodiment provides a commercial vehicle window stall current active calibration method and system, comprising:

[0056] Step 102, obtaining the starting current and normal running current of the window motor, and recording them as the first running current and the second running current;

[0057] Wherein, due to the excessive starting current of the window movement, it will exceed the stall current of the jitter current, in order to prevent the starting current from affecting the calibration process, so as to correctly identify the starting current and filter it.

[0058] It should be pointed out that the working current will be generated when the window is running normally, but due to the difference of the window motor characteristics, the working current of a window motor may be greater than that of another window motor. Therefore, the stall current of each window motor needs to be calibrated respectively, so as to realize the anti-pinch function of each window.

[0059] Step 104, presetting the stall times and stall positions, obtaining the jitter current peak value of all windows after the stall jitter;

[0060] Wherein, the preset stall times and stall positions include all windows including the main and co-pilot positions and the main and co-pilot corresponding rear position windows, the main driver position window is the first window, the co-pilot position window is the second window, the main driver corresponding rear position window is the third window, and the co-pilot corresponding rear position window is the fourth window.

[0061] Further, the preset stall times and stall positions include that the stall position is the highest point and the lowest point of the window, and the first window stall times are 11 times of the highest point stall and 10 times of the lowest point stall, the second window stall times are 15 times of the highest point stall and 16 times of the lowest point stall, the third window stall times are 8 times of the highest point stall and 8 times of the lowest point stall, and the fourth window stall times are 8 times of the highest point stall and 8 times of the lowest point stall.

[0062] In an optional embodiment, the different window opening times, different continuous stall times and corresponding motor wear rate values are shown in Table 1:

[0063] Table 1 Different window opening times, different continuous stall times and corresponding motor wear rate values

[0064]

[0065] As can be seen from Table 1, the preset stall times are preferred, and from the historical experimental data, when the motor wear rate is 0.45%-0.5% and the continuous jitter peak current fluctuation is 2%-3%, the most accurate stall data value of the window motor can be obtained, and the first window stall times can also be set to 10 times of the highest point stall and 11 times of the lowest point stall, and the second window stall times can also be set to 16 times of the highest point stall and 15 times of the lowest point stall.

[0066] Step 106, obtaining the calibration stall current value of all windows according to the jitter current peak value and the stall times;

[0067] When the user needs to enter the calibration mode, the interior position light is turned on, and it is determined whether the car key is continuously turned 3 times within 15 seconds;

[0068] Further, if the determination is negative, the vehicle window calibration mode fails, and the user uses the normal vehicle function;

[0069] Further, if the determination is positive, the vehicle window calibration mode succeeds, the user uses the vehicle window calibration mode, and the vehicle-mounted danger warning light flashes once, prompting the user that the vehicle window calibration mode has been entered;

[0070] Further, after the user enters the vehicle window calibration mode, the user selects any vehicle window for calibration. If the user selects the first vehicle window, the calibration mode needs to be started after the first vehicle window motor is lowered to the lowest position, and the jitter peak current of the highest point of 11 times and the lowest point of 10 times is continuously recorded. The highest and lowest peak currents are removed, the average peak current value of the remaining peak currents is obtained, the calibration current value is set to 80% of the average peak current value, and is recorded as the first calibration value.

[0071] It should be noted that the calibration current value is set to 80% of the average peak current value, which is a preferred scheme. In the design, if the calibration current exceeds 80% of the average peak current value, the vehicle window motor will fail to operate, the vehicle window motor will be burned out or a jamming situation will occur. If the calibration current is lower than 80% of the average peak current value, the vehicle window motor will be too sensitive to the highest point, and if the user touches the vehicle window, the vehicle window will be calibrated, which will increase the wear degree of the motor.

[0072] Further, if the user selects the second vehicle window, the calibration mode needs to be started after the second vehicle window motor is lowered to the highest position, and the jitter peak current of the highest point of 15 times and the lowest point of 16 times is continuously recorded. The highest and lowest peak currents are removed, the average peak current value of the remaining peak currents is obtained, the calibration current value is set to 80% of the average peak current value, and is recorded as the second calibration value;

[0073] Further, if the user selects the third vehicle window or the fourth vehicle window, the calibration mode can be directly started in any vehicle window state, and the jitter peak current of the highest point of 8 times and the lowest point of 8 times is continuously recorded. The highest and lowest peak currents are removed, the average peak current value of the remaining peak currents is obtained, the calibration current value is set to 80% of the average peak current value, and is recorded as the third calibration value.

[0074] It should be noted that when any vehicle window is calibrated, the vehicle window motor stops running at the highest point, and it is determined that the calibration is successful. At this time, the danger warning light flashes three times, prompting the user that the vehicle window calibration mode has been completed;

[0075] When any window is calibrated, if the window motor does not stop running at the stall position, it is judged that the calibration fails, at this time the hazard warning light is always on, and the vehicle-mounted warning horn rings once, prompting the user that the window calibration mode is not completed, and needs to be calibrated again. After the user performs the recalibration operation, the hazard warning light is turned off.

[0076] Step 108, preset the rated value of the calibrated stall current value offset, judge the size relationship between the offset and the rated value, and update the calibration.

[0077] Further, the calibration update includes setting the first window calibrated stall current value offset rated value to 4.2% of the first calibration value;

[0078] Further, the second window calibrated stall current value offset rated value is set to 3.5% of the second calibration value;

[0079] Further, the third window and the fourth window calibrated stall current value offset rated value is set to 5.0% of the third calibration value.

[0080] In an optional embodiment, the effect of different window calibrated stall current values with different offset values is shown in Table 2:

[0081] Table 2 is the effect of different window calibrated stall current values with different offset values

[0082]

[0083] It should be noted that the current fluctuation value is obtained by experimental test. When the current fluctuation value is less than 2%-3%, it is a normal current fluctuation. When the current fluctuation value is greater than 3%, it indicates that the window motor has a preset external wear. If the calibrated stall current value offset is less than the rated value, no operation is performed.

[0084] It should be noted that if the first window calibrated stall current value offset is greater than the rated value, the CAN bus is used to send the first-level recalibration information to the instrument. After the user obtains the first-level recalibration information, the first window and the second window are recalibrated to the stall current value.

[0085] Further, if the second window calibrated stall current value offset is greater than the rated value, the CAN bus is used to send the second-level recalibration information to the instrument. After the user obtains the second-level recalibration information, the second window is recalibrated to the stall current value.

[0086] Further, if the third window or the fourth window calibrated stall current value offset is greater than the rated value, the CAN bus is used to send the third-level recalibration information to the instrument. After the user obtains the third-level recalibration information, the first window, the second window, the third window, and the fourth window are all recalibrated to the stall current value.

[0087] Further, if there are two or more than two window calibrated stall current value offset greater than the rated value, the first window, the second window, the third window and the fourth window are all recalibrated stall current value.

[0088] A commercial vehicle window stall current active calibration system, characterized in that: comprising current acquisition module, peak acquisition module, calibrated stall current value acquisition module and judgment update module,

[0089] The current acquisition module is used for acquiring the starting current and the normal running current of the window motor and recording them as the first running current and the second running current;

[0090] The peak acquisition module is used for presetting the stall times and the stall positions, and acquiring the peak value of the jitter current after all the windows appear stall jitter;

[0091] The calibrated stall current value acquisition module is used for acquiring the calibrated stall current value of all the windows according to the jitter current peak value and the stall times;

[0092] The judgment update module is used for presetting the rated value of the calibrated stall current value offset, judging the size relationship between the offset and the rated value, and performing calibration update.

[0093] The above-mentioned each unit module can be embedded in or independent of the processor in the computer device in hardware form, or can be stored in the memory in the computer device in software form, so as to call and execute the operation corresponding to each module by the processor.
