Description

Technical Field

[0001] The invention relates to the technical field of automobile doors, and in particular to a method for testing the resistance of a door operation system, a testing system and a door. Background Art

[0002] There are many operating parts in the car door system, among which the operating parts of the front door of the car mainly include door glass, foldable rearview mirror, adjustable rearview mirror lens, etc., and the operating parts of the rear door of the car are mainly door glass. During the production process, there are deviations in the size of the door sheet metal, the size of the door glass guide rail, the size of the glass sealing strip, the lack of glass sealing strip coating, and the inadequate installation of the glass sealing strip, all of which will cause the resistance of the door operation system to increase during operation. In the aftermarket, as the car is used, there are problems such as aging of parts, accumulation of dust and dirt between parts, and the resistance of the door operation system during operation will also increase. The increase in the resistance of the door operation system may cause the door glass to get stuck during operation or the door glass operation motor to burn out, which will have a great impact on the driver's driving comfort and safety.

[0003] In the prior art, the method for measuring the resistance of the door operating system is mainly to disassemble the door interior components and remove the door lifting motor, and use a dynamometer to measure the door glass of the door system. This operation method takes a long time to disassemble and is difficult to operate. It is impossible to perform 100% inspection and monitoring of each vehicle during the production process, and it is impossible to perform inspection and monitoring during use. It can often only be analyzed and maintained after a problem occurs, which will lead to strong after-sales complaints from customers. There is currently no effective means to measure the operating resistance of the folding rearview mirror and the operating resistance of the rearview mirror lens. Summary of the invention

[0021] The present invention provides a method for testing the resistance of a vehicle door operation system, a testing system and a vehicle door, which have the following beneficial effects:

[0022] (1) The operating resistance of each operating unit in the door operating system is reflected by obtaining the current current value of the door operating system. When the current current value is not less than the product of the current threshold of the operating unit corresponding to the current current value and the deviation coefficient, it means that the operating resistance of the operating unit is large.

Therefore, the test method of the present application can not only test the operating resistance of the door glass, but also effectively measure the operating resistance of the folding rearview mirror and the operating resistance of the rearview mirror lens.

[0024] (3) The test system of the present application can be installed in a vehicle door to track and measure the running resistance of the door glass, the running resistance of the folding rearview mirror, and the running resistance of the rearview mirror lens. When any of the running resistances of the door glass, the running resistance of the folding rearview mirror, and the running resistance of the rearview mirror lens increases, it can be displayed through the display module, which can remind the user at the first time the problem occurs to prevent the problem from further deteriorating, thereby playing a role in early warning and early resolution.

[0025] (4) The test method and test system of the present application only sort out or store the door glass operating current thresholds at ambient temperatures that are integer multiples of 10. When the current ambient temperature value is not an integer multiple of 10, the door glass operating current thresholds at ambient temperatures that are integer multiples of 10 that are sorted out or stored are used to calculate the door glass operating current thresholds at the current ambient temperature value using the linear interpolation method. This can obtain infinite corresponding thresholds under the premise of limited data, which helps to reduce the workload of sorting and lower the requirements for the storage module. By obtaining the current value before the door controller, that is, the current before commutation, the requirements for the current acquisition sensor are lower, which helps to reduce costs.

[0032] In order to at least partially solve one or more of the above problems and other potential problems, an embodiment of the present disclosure provides a method for testing the resistance of a vehicle door operation system, comprising the following steps:

[0033] Step 1: Obtain historical data of the normal operation of the door operation system, and sort out the door glass operation current threshold, rearview mirror folding current threshold, and rearview mirror lens adjustment current threshold under different ambient temperatures based on the historical data; as a preferred embodiment, when sorting out the door glass operation current threshold under different ambient temperatures, only sort out the door glass operation current threshold under ambient temperatures that are integer multiples of 10, for example, sort out the operation current of the door glass under normal operation at ambient temperatures of -40°C, -30°C, -20°C, -10°C, 0°C, 10°C, 20°C, 30°C, 40°C and 50°C, and use it as the door glass operation current threshold under the corresponding ambient temperature.

[0034] Step 2: Obtain the current current value and the current ambient temperature value from the current door operation system; In a specific embodiment, the door controller in the door operation system in the prior art has a current value acquisition function, and an outside temperature sensor is installed on the car. After the outside temperature sensor detects the ambient temperature, it will be sent to the car bus. The door controller can read the ambient temperature value from the car bus. Therefore, the present application can obtain the current current value and the current ambient temperature value through the door controller. In a preferred embodiment, a current acquisition sensor is installed in the door operation system. The current acquisition sensor is preferably a current acquisition sensor of model ACS712, which is used to detect the current value in the door operation system, which helps to improve the current detection accuracy to improve the accuracy of the current value; more preferably, the current acquisition sensor is connected in series to the front end of the door controller to detect the current before the commutation, that is, to obtain the current value in front of the door controller in the door operation system, which helps to reduce the requirements for the current acquisition sensor to reduce the cost. In a preferred embodiment, an outside temperature sensor is installed in the door operation system to detect the ambient temperature.

[0035] Step 3: Determine the magnitude of the current current value obtained in step 2, and determine the type of the currently operating drive mechanism in the door operation system according to the determined magnitude result, wherein the drive mechanism type includes a drive mechanism for door glass operation, a drive mechanism for rearview mirror folding, and a drive mechanism for rearview mirror lens adjustment, and the drive mechanism may be a motor or electric cylinder part. In a specific embodiment, when the magnitude of the current current value is 1A or above, for example, the current current value is 3A, 5A, or 7A, the type of the currently operating drive mechanism in the door operation system is a drive mechanism for door glass operation; when the magnitude of the current current value is 0.1A, for example, the current current value is 0.3A, 0.5A, or 0.7A, the type of the currently operating drive mechanism in the door operation system is a drive mechanism for rearview mirror folding; when the magnitude of the current current value is 1mA, for example, the current current value is 3mA, 5mA, or 7mA, the type of the currently operating drive mechanism in the door operation system is a drive mechanism for rearview mirror lens adjustment.

[0036] Step 4: According to the type of the currently operating drive mechanism determined in step 3, or according to the type of the currently operating drive mechanism determined in step 3 and the current ambient temperature value obtained in step 2, combined with the sorting result in step 1, determine the current threshold value corresponding to the currently operating drive mechanism. In a specific embodiment, when the type of the currently operating drive mechanism determined in step 3 is a drive mechanism for rearview mirror folding, the current threshold value corresponding to the currently operating drive mechanism is the rearview mirror folding current threshold value; when the type of the currently operating drive mechanism determined in step 3 is a drive mechanism for rearview mirror lens adjustment, the current threshold value corresponding to the currently operating drive mechanism is the rearview mirror lens adjustment current threshold value; when the type of the currently operating drive mechanism determined in step 3 is a drive mechanism for door glass operation, the current threshold value corresponding to the currently operating drive mechanism is the door glass operation current threshold value under the current ambient temperature value; in a preferred embodiment In step 1, only the door glass operating current thresholds at ambient temperatures that are integer multiples of 10 are sorted out. In this step, when the current ambient temperature value is an integer multiple of 10, the door glass operating current threshold at the current ambient temperature value in step 1 is directly used; when the current ambient temperature value is not an integer multiple of 10, the door glass operating current threshold at ambient temperatures that are two integer multiples of 10 adjacent to the current ambient temperature value in step 1 is used to calculate the door glass operating current threshold at the current ambient temperature value using the linear interpolation method. Specifically, the calculation process of calculating the door glass operating current threshold at the current ambient temperature value using the linear interpolation method is:

[0037]

[0038] The calculation formula for converting the door glass operating current threshold under the current ambient temperature value is:

[0039]

[0040] in, is the current ambient temperature value, They are two ambient temperatures that are integer multiples of 10 adjacent to the current ambient temperature value. are respectively the operating current thresholds of the door glass at two ambient temperatures that are integer multiples of 10 adjacent to the current ambient temperature value, It is the door glass operating current threshold under the current ambient temperature value.

[0041] Step 5: Compare the current current value obtained in step 2 with the product of the current threshold value determined in step 4 and the deviation coefficient. Preferably, the value of the deviation coefficient is 1.1 to 1.5. When the current current value obtained in step 2 is not less than the product of the current threshold value determined in step 4 and the deviation coefficient, the operating resistance of the door glass operation, rearview mirror folding or rearview mirror lens adjustment driven by the currently operating driving mechanism is large. As an example, the deviation coefficient is 1.2. When the current threshold corresponding to the currently running driving mechanism in step 4 is the rearview mirror folding current threshold, if the current current value is not less than 1.2 times the rearview mirror folding current threshold, it means that the operating resistance of the rearview mirror folding is large; when the current threshold corresponding to the currently running driving mechanism in step 4 is the rearview mirror lens adjustment current threshold, if the current current value is not less than 1.2 times the rearview mirror lens adjustment current threshold, it means that the operating resistance of the rearview mirror lens adjustment is large; when the current threshold corresponding to the currently running driving mechanism in step 4 is the door glass operation current threshold under the current ambient temperature value, if the current current value is not less than 1.2 times the door glass operation current threshold under the current ambient temperature value, it means that the operating resistance of the door glass operation under the current ambient temperature value is large.

[0042] Just as an example, the current ambient temperature value is 25°C, the current current value is 2.8A, and the deviation coefficient is selected as 1.2. According to the magnitude of the current current value, it can be determined that the type of the currently operating drive mechanism in the door operation system is the drive mechanism for the door glass operation; according to the determination that the type of the currently operating drive mechanism is the drive mechanism for the door glass operation, the current threshold corresponding to the currently operating drive mechanism is the door glass operation current threshold at the current ambient temperature value; since the current ambient temperature value is not an integer multiple of 10, the door glass operation current thresholds at 20°C and 30°C can be used, and the door glass operation current threshold at 25°C can be calculated using the above calculation formula; then compare the size relationship between 2.8A and 1.2 times the door glass operation current threshold at 25°C. When 2.8A is not less than 1.2 times the door glass operation current threshold at 25°C, it indicates that the operation resistance of the door glass at 25°C is large.
