[0021] Below, the exemplary embodiments according to the present application will be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application, and it should be understood that the present application is not limited to the exemplary embodiments described here.

[0022] Figure 1 FIG. 1 is a flow chart of a method for evaluating the anti-pinch force of a seat motor provided by an exemplary embodiment of the present application. Figure 1 As shown, the seat motor anti-pinch force evaluation method includes the following steps: Step 110: Control the motor of the seat to be evaluated to drive the corresponding moving component to move on the electric adjustment path.

[0023] The electric adjustment path includes test points. The present application controls the motor of the seat to be evaluated to drive the corresponding moving parts to move along the preset electric adjustment path, for example, controls the seat to be evaluated to move along a specific electric adjustment path in the front-to-back direction (with the vehicle operation as a reference), so as to realize the movement state of the seat to be evaluated during the actual electric adjustment process.

[0024] Step 120: Obtain operating parameters of the seat motor to be evaluated during operation.

[0025] The present application obtains operating parameters of the seat motor to be evaluated in real time during its operation, such as the current, voltage, speed, Hall position, etc. of the seat motor to be evaluated, and determines the operating state of the seat motor to be evaluated when the anti-pinch function is triggered by obtaining the operating parameters of the seat motor to be evaluated.

[0026] Step 130: Measure the clamping force of the moving component on the simulated obstacle.

[0027] Wherein, the simulated obstacle is set at the test point. The present application sets a test point (such as an important position or a position where clamping events are prone to occur) on the electric adjustment path, and sets a simulated obstacle at the test point to simulate the clamping force of the moving parts of the seat to be evaluated on the simulated obstacle when there is an obstacle at the test point, so as to measure the clamping force of the seat to be evaluated on the obstacle during the electric adjustment process. Optionally, the present application can also adjust the surface stiffness of the simulated obstacle according to actual needs to simulate different types of obstacles, thereby further improving the evaluation accuracy of the anti-pinch function of the seat motor to be evaluated.

[0028] Step 140: Evaluate the anti-pinch function of the seat motor to be evaluated based on the operating parameters and the clamping force.

[0029] After obtaining the operating parameters of the seat motor to be evaluated and the clamping force of the moving parts on the simulated obstacle, the present application evaluates the anti-pinch function of the seat motor to be evaluated based on the operating parameters of the seat motor to be evaluated and the clamping force of the moving parts on the simulated obstacle. For example, if the clamping force of the moving parts on the simulated obstacle is too large, it may cause damage to objects and injury to passengers, while if the clamping force of the moving parts on the simulated obstacle is too small, the seat to be evaluated may be easily mistriggered during the electric adjustment process, thereby affecting the operability of the passengers.

[0030] The present application provides a seat motor anti-pinch force evaluation method, which controls the motor of the seat to be evaluated to drive the corresponding moving part to move on an electric adjustment path; wherein the electric adjustment path includes test points; obtains operating parameters of the seat motor to be evaluated during operation; measures the clamping force of the moving part on a simulated obstacle; wherein the simulated obstacle is set at the test points; based on the operating parameters and the clamping force, evaluates the anti-pinch function of the seat motor to be evaluated; that is, by setting the test points on the electric adjustment path, controlling the moving part of the seat to be evaluated to move on the electric adjustment path and obtaining the operating parameters of the seat motor to be evaluated and the clamping force of the moving part on the simulated obstacle, the anti-pinch function is evaluated according to the operating parameters of the seat motor to be evaluated and the clamping force of the moving part on the simulated obstacle, so as to realize the anti-pinch function evaluation of the electric seat, and the operating parameters and the clamping force of the seat motor to be evaluated are comprehensively evaluated to improve the accuracy of the evaluation result.

[0031] In one embodiment, the operating parameters include the rotational speed and / or current of the seat motor to be evaluated during operation; wherein, the specific implementation method of the above step 140 may be: based on the rotational speed and / or current of the seat motor to be evaluated during operation, determine the triggering moment of the anti-pinch function of the seat motor to be evaluated; based on the clamping force at the triggering moment of the anti-pinch function, evaluate the anti-pinch function of the seat motor to be evaluated.

[0032] The anti-pinch function of the electric seat can be triggered according to the speed, speed deceleration, current and current change rate of the seat motor. For example, during the movement of the electric seat, the anti-pinch function is triggered after the speed of the seat motor drops to a preset speed threshold and lasts for a preset time, the anti-pinch function is triggered after the speed deceleration of the seat motor reaches a preset deceleration threshold and lasts for a preset time, the anti-pinch function is triggered after the current of the seat motor increases to a preset current threshold and lasts for a preset time, and the anti-pinch function is triggered after the current growth rate of the seat motor reaches a preset change rate threshold and lasts for a preset time, wherein the speed threshold, deceleration threshold, current threshold, change rate threshold and preset time can be calculated based on the performance parameters of the seat motor to be evaluated. The present application collects the speed and current of the seat motor to be evaluated during operation to determine the triggering moment of the anti-pinch function of the seat motor to be evaluated based on the speed or current, and evaluates the anti-pinch function of the seat motor to be evaluated based on the clamping force at the time when the anti-pinch function of the seat motor is triggered, that is, the clamping force of the seat motor to be evaluated when the anti-pinch function is triggered (the maximum clamping force of the moving part on the simulated obstacle) is evaluated.

[0033] In one embodiment, the specific implementation of the above step 140 can be: if the difference between the clamping force at the time of triggering the anti-pinch function and the preset clamping force threshold is less than the preset difference threshold, it is determined that the anti-pinch function of the seat motor to be evaluated is normal.

[0034] If the difference between the clamping force at the time of triggering the anti-pinch function and the preset clamping force threshold is small (smaller than the preset difference threshold), it means that the clamping force of the seat motor to be evaluated when the anti-pinch function is triggered is appropriate, and it can be determined that the anti-pinch function of the seat motor to be evaluated is normal or qualified. Optionally, the present application can further evaluate the good or bad of the seat motor to be evaluated based on the interval range of the difference between the clamping force at the time of triggering the anti-pinch function and the preset clamping force threshold.

[0035] In one embodiment, the specific implementation of step 140 may be: if the difference value is greater than or equal to the difference threshold, it is determined that the anti-pinch function of the seat motor to be evaluated is abnormal.

[0036] If the difference between the clamping force measured at the time the anti-pinch function is triggered and the preset clamping force threshold is large (greater than or equal to the difference threshold), it means that the clamping force of the seat motor to be evaluated when the anti-pinch function is triggered is too large or too small. At this time, it can be determined that the anti-pinch function of the seat motor to be evaluated is abnormal or unqualified.

[0037] If the difference between the clamping force at the time the anti-pinch function is triggered and the preset clamping force threshold measured on the entire electric adjustment path or at key test points of the seat motor to be evaluated is large, it is necessary to further determine whether the cause of the large difference is the hardware structure of the seat to be evaluated or a software problem of the seat motor to be evaluated, and take corresponding optimization measures based on the cause, and re-test and evaluate the seat motor to be evaluated after the optimization is completed.

[0038] In one embodiment, the electric adjustment path includes multiple test points; wherein, the above-mentioned seat motor anti-pinch force evaluation method may also include: dividing the electric adjustment path into multiple segmented paths to obtain multiple test points; wherein, the test points are the connection points of the segmented paths at both ends of adjacent segments; measuring the clamping force of the moving component on the simulated obstacle includes: measuring the clamping force of the moving component on the simulated obstacle when the simulated obstacle is at each test point.

[0039] In order to accurately evaluate the anti-pinch function of the seat motor to be evaluated, the present application can divide the electric adjustment path into multiple segmented paths, and determine the connection points of adjacent segmented paths as test points to obtain the clamping force of multiple test points on the electric adjustment path. By measuring the clamping force of the moving parts on the simulated obstacle when the simulated obstacle is at each test point, the anti-pinch function of the seat motor to be evaluated can be better reflected.

[0040] For example, the present application can set two soft stop points between two hard stop points of the electric adjustment path, wherein the hard stop point is the physical stop point at both ends of the motor adjustment path, and the soft stop point is the software stop point on the motor adjustment path located between the two hard stop points and close to the hard stop point (i.e., the end point of the electric adjustment path of the motor of the seat to be evaluated set by the software). The present application sets the soft stop point to reduce the hardware loss generated when the seat to be evaluated reaches the hard stop point during the evaluation process.

[0041] When the seat to be evaluated moves backward, the present application calculates the difference between the distance between the front and rear soft stop points of the seat cushion slide rail and the length of the seat cushion, and then divides the difference into multiple parts to obtain multiple test points. A simulated obstacle is placed at the test point directly behind the seat cushion, and the force sensor arranged on the simulated obstacle is perpendicular to the force surface of the seat cushion to measure the horizontal backward clamping force when the seat cushion moves backward.

[0042] When the seat to be evaluated moves forward, this application calculates the difference between the distance between the front and rear soft stop points of the seat cushion slide rail and the length of the seat cushion, and then divides the difference into multiple parts to obtain multiple test points. A simulated obstacle is placed at the test point directly in front of the seat cushion, and the force sensor set on the simulated obstacle is perpendicular to the force surface of the seat cushion to measure the horizontal backward clamping force when the seat cushion moves forward.

[0043] When the seat back moves backward, the present application chooses to divide the full stroke of the seat back into multiple parts to obtain multiple test points, and places a simulated obstacle at the test point directly behind the seat back. The force sensor set on the simulated obstacle is perpendicular to the force surface of the seat back, and measures the clamping force in the tangential direction of the motion trajectory when the seat back moves backward.

[0044] When the seat back moves forward, the present application chooses to divide the full stroke of the seat back into multiple parts to obtain multiple test points, and places a simulated obstacle at the test point directly in front of the seat back. The force sensor set on the simulated obstacle is perpendicular to the force surface of the seat back, and measures the clamping force in the tangential direction of the motion trajectory when the seat back moves forward.

[0045] In one embodiment, the above-mentioned seat motor anti-pinch force evaluation method may further include: obtaining environmental parameters of the environment in which the seat motor to be evaluated is located; based on the operating parameters and the clamping force, evaluating the anti-pinch function of the seat motor to be evaluated includes: based on the environmental parameters, the operating parameters and the clamping force, evaluating the anti-pinch function of the seat motor to be evaluated.

[0046] Since the operating status of the seat motor to be evaluated under different environmental parameters may be different, during the test and evaluation process, the present application obtains the environmental parameters (such as temperature, etc.) of the environment in which the seat motor to be evaluated is located, and combines the environmental parameters, the operating parameters of the seat motor to be evaluated, and the clamping force to comprehensively evaluate the anti-pinch function of the seat motor to be evaluated. For example, the present application evaluates the anti-pinch function of the seat motor to be evaluated in a normal temperature environment, a high temperature environment, and a low temperature environment to comprehensively determine the anti-pinch function of the seat motor to be evaluated, wherein the normal temperature environment corresponds to a temperature range of 20°C to 30°C, an air pressure of standard air pressure, and a humidity of 40%RH to 60%RH, the high temperature environment corresponds to a temperature range of 40°C to 60°C, an air pressure of standard air pressure, and a humidity of 40%RH to 60%RH, and the low temperature environment corresponds to a temperature range of -40°C to -20°C, an air pressure of standard air pressure, and a humidity of 40%RH to 60%RH.

[0047] Before conducting the test evaluation, the present application may also perform evaluation preparation operations on the seat to be evaluated or the vehicle to be evaluated. Specifically, the seat to be evaluated or the vehicle to be evaluated may be placed in the environmental conditions to be measured for 30 minutes to 1 hour, and then the motor of the seat to be evaluated is controlled to start to complete self-learning (reaching the hard stop point to reset the zero position), and an initial position is set. The anti-pinch function is triggered once at the initial position to analyze whether the various data measured when the anti-pinch function is triggered is reasonable, such as determining whether the measured clamping force is within a reasonable range, or whether the various data have numerical values, etc. The anti-pinch function is triggered at the initial position to detect whether the test evaluation system is normal.

[0048] After the measurement is completed, the present application can generate a test evaluation report based on the clamping force measured at each test point. Optionally, the present application can also save the clamping force measured at each test point, the operating parameters of the seat motor to be evaluated, and other data for subsequent analysis and optimization.
