A method, an apparatus, a vehicle, and a computer-readable storage medium for monitoring performance of an electric sliding door according to embodiments of the present invention are described below with reference to fig. 1 to 2.

The electric sliding door is one of the high-end functions currently applied to automobiles. When the electric sliding door technology is originally applied to automobiles, the electric sliding door technology is mainly assembled in high-end vehicles, and the high-end experience brought by the electric sliding door technology conquers a plurality of vehicle owners. However, as the electric sliding door is more and more widely used, the problem feedback of the electric sliding door is more and more, and the inventor of the present application finds that one of the main problems is that the operation quality of the electric sliding door is affected, so that the normal use time of the electric sliding door is shortened. This application aims at improving the quality that electronic sliding door used on the vehicle, improves the life of electronic sliding door.

Fig. 1 is a flowchart of a method of monitoring performance of an electric sliding door according to an embodiment of the present invention. As shown in fig. 1, the method for monitoring the performance of the electric sliding door comprises the following steps:

step S1: and acquiring a driving instruction of the electric sliding door, and calling a vehicle state in response to the driving instruction.

Specifically, the electric sliding door driving command is used for instructing a driving system for controlling the electric sliding door to drive the electric sliding door to move. The electric sliding door driving instruction can be sent by a user through a switch key outside the door or through a user terminal and the like, after the driving instruction is received, the electric sliding door is controlled to move, at the moment, the electric sliding door is in a driving process, and meanwhile, the vehicle state, such as the current vehicle body angle of the vehicle and the wind-receiving state of the vehicle, such as whether the vehicle is in wind or not, is called in response to the driving instruction. The body angle is the grade on which the vehicle is located.

Step S2: and acquiring the driving current in the driving process of the electric sliding door in real time.

Specifically, after receiving a driving instruction of the electric sliding door, the driving system drives the electric sliding door to move according to the driving instruction, the electric sliding door is in a driving process, and a driving current of the electric sliding door in the driving process is obtained. In a specific embodiment, the driving current during the driving of the electric sliding door can be obtained by a current sensor. When the electric sliding door moves, the motor of the driving system is in a working state, and the driving current of the driving system can be acquired through the current sensor. Or, the operating parameters such as the operating voltage and power of the driving system can be obtained, and the driving current of the driving system can be calculated by some current calculation methods. Specifically, the driving current of the driving system may include a driving current of the driving system at a certain time, or include a driving current of the driving system within a period of time, where the driving current is a current curve corresponding to the driving current of the driving system within the period of time, that is, a driving current curve.

And step S3: and judging whether the electric sliding door is in an abnormal state or not according to the vehicle state and the driving current. The electric sliding door is comprehensively judged whether to be in an abnormal state or not by combining the vehicle body angle of the vehicle, the information such as the wind receiving state and the driving current, therefore, the influence of the vehicle state on the driving current is considered, the accuracy of abnormal state detection is favorably improved, and when the electric sliding door is abnormal, accurate prompt and early warning information is favorably sent out, so that the safety and the reliability of the electric sliding door are improved, and the service life of the electric sliding door is favorably prolonged.

And step S4: and if so, generating prompt information. Namely, when judging that the electric sliding door is in an abnormal state, the electric sliding door sends out prompt early warning information, so that the safety and reliability of the electric sliding door are improved, and the service life of the electric sliding door is favorably prolonged.

In a specific embodiment, at least one of sound prompt information and light prompt information can be sent out, so that the reliability of the alarm prompt is improved.

Therefore, the method for monitoring the performance of the electric sliding door acquires the driving instruction of the electric sliding door, calls the vehicle state in response to the driving instruction, acquires the driving current in the driving process of the electric sliding door in real time, judges whether the electric sliding door is in an abnormal state or not according to the vehicle state and the driving current, and generates prompt information if the electric sliding door is in the abnormal state. Therefore, whether the electric sliding door is in an abnormal state or not can be judged according to the vehicle state and the driving current in the driving process of the electric sliding door, and when the judgment is abnormal, prompt information is sent out, so that the driving process of the electric sliding door can be monitored in real time and prompted by an alarm, the safety and the reliability of the electric sliding door are improved, the service life of the electric sliding door is favorably prolonged, the influence of the vehicle state on the driving current is considered, and the accuracy of detecting the abnormal state is favorably improved.

In one embodiment of the invention, the vehicle conditions include at least a body angle and a wind condition. The vehicle body angle is information such as the slope of the vehicle, the wind state, whether the vehicle is being winded, the strength and direction of the wind, and the like.

In one embodiment of the present invention, the step S3 of determining whether the electric sliding door is in the abnormal state according to the vehicle state and the driving current includes: when the vehicle is not in a windy state, when the absolute value of the difference value between the driving current and the prestored working current is larger than a preset value, the electric sliding door is judged to be in an abnormal state.

Specifically, the preset value is a preset empirical value, which is set according to a magnitude indicating a deviation of the driving current from the contrast current. When the deviation of the driving current and the comparison current is larger than a preset value, the deviation of the driving current and the comparison current is considered to be larger, at the moment, the electric sliding door is considered to be abnormal, namely, in an abnormal state, for example, a foreign object blockage or a driving system fault occurs on a moving path, so that the load of the driving system is changed, and the working current of the driving system is changed accordingly. On the other hand, if the deviation between the driving current and the comparison current does not exceed the preset value, the deviation between the driving current and the comparison current is considered to be small, and the electric sliding door is considered to have no abnormality, possibly because parameters such as voltage are unstable or other factors slightly influence the current, so that the current slightly changes.

Specifically, when the vehicle is not in a wind-affected state, the wind power is small or no wind at the moment, and the driving process of the electric sliding door is not influenced or the influence is small and negligible, the driving current is compared with the prestored working current, and when the absolute value of the difference value between the driving current and the prestored working current is greater than a preset value, it is determined that the electric sliding door is in an abnormal state, such as the occurrence of foreign object blocking on a moving path or the failure of a driving system. At the moment, prompt information is generated and sent to remind a user that the electric sliding door is abnormal, and the electric sliding door should be overhauled and disposed in time, so that the safety and the reliability of the electric sliding door are improved, and the service life of the electric sliding door is prolonged.

Specifically, the driving current may include a driving current of the driving system at a certain time, or include a driving current of the driving system during a period of time, that is, a driving current curve corresponding to the driving current during the period of time, and accordingly, the working current, that is, the contrast current, also includes a contrast current of the driving system at a certain time, or include a contrast current of the driving system during a period of time, that is, a current curve corresponding to the contrast current during the period of time, that is, a contrast current curve. Further, determining a difference between the drive current and the contrast current comprises: comparing the driving current of the driving system at a certain moment with the comparison current at the corresponding moment, and determining the difference value of the driving current and the comparison current at the certain moment, or comparing the driving current curve of the driving system at a certain time with the comparison current curve at the corresponding time period, and determining the deviation between the driving current curve at the certain time and the comparison current curve.

Furthermore, the driving current of the electric sliding door in the driving process is related to the load of the driving motor, when the load changes, the driving current or the driving current curve fluctuates to some extent, when an anti-pinch scene appears, namely, when the electric sliding door is abnormal, the load of the driving system changes along with the fluctuation, at the moment, the load of the driving system is different from the load of the driving system in normal work, and whether the electric sliding door is abnormal or not can be accurately judged by detecting the difference, for example, the foreign matter blocking or the driving system fault appears on the moving path. Therefore, when an abnormality occurs in the driving process of the electric sliding door, the load of the driving system changes, and at the moment, the driving current changes, such as becomes larger or smaller, so that a certain difference value is generated with the normal working current of the driving system before the load changes, namely when no abnormality occurs, whether the abnormality exists is detected according to the difference value, and the electric sliding door can be controlled to move. Generally, when the electric sliding door is abnormal, the driving current is greatly deviated from the current in normal operation, and therefore, when the deviation between the driving current of the electric sliding door and the contrast current is large, it is determined that the electric sliding door is abnormal, that is, in an abnormal state. Further, when the abnormity appears, the moving direction of the electric sliding door can be controlled, for example, the electric sliding door is controlled to move in the opposite direction, so that the anti-pinch function is realized, an anti-pinch strip is not required to be arranged, the cost of the whole vehicle is reduced, meanwhile, the electric sliding door is prevented from being damaged due to the abnormity, the service life of the electric sliding door is influenced, and the safety and the reliability of the electric sliding door are improved.

In one embodiment of the invention, the pre-stored working current is the current obtained by testing the electric sliding door in a normal working state under different angles of the vehicle body when the vehicle is not in a wind-affected state.

Specifically, when the vehicle is not in a windy state, the load of the electric sliding door changes differently due to the gravity component when the electric sliding door is in different slopes, and thus the deviation between the driving current and the normal operating current is different when the electric sliding door is in different slopes. Therefore, in order to eliminate the load change of normal work of the driving motor under different slopes, the normal working current of the electric sliding door under different angles can be tested in advance and used as the comparison current under the angle, different comparison currents are selected according to the pitching angle of a vehicle during normal work, and the current under different angles is prevented from being clamped. That is to say, under different slope angles, electronic sliding door all corresponds by there is different operating current, contrast electric current promptly, and these contrast electric current under different slope angles are for testing in advance and obtain. Before the difference of the working current and the comparison current is determined, the vehicle is firstly determined not to be in a wind-affected state, the gradient angle of the position where the electric sliding door is located is obtained, the comparison current of the driving motor corresponding to the gradient angle is selected according to the gradient angle, therefore, the working current and the comparison current are in the same gradient angle working condition, the difference error caused by different gradient angles can be eliminated, the accuracy of the difference is improved, and the control accuracy of the electric sliding door is improved.

In one embodiment of the present invention, after determining that the electric sliding door is in an abnormal state, the method further includes: and controlling the electric sliding door to move towards the direction opposite to the current moving direction until the electric sliding door is in a fully-opened state or a fully-closed state.

Specifically, when the deviation between the driving current and the comparison current is greater than a preset value, the deviation between the driving current and the comparison current is considered to be large, at this time, the electric sliding door is considered to be abnormal and is in an abnormal state, if foreign matters exist on a moving path, an anti-pinch function is triggered, namely the foreign matters block the electric sliding door from moving, so that the load of the driving system is changed, and the working current of the driving system is changed accordingly. Under this condition, control electronic sliding door moves towards the direction opposite with the current direction of movement, until being in full open mode or full cut-off state, that is, control electronic sliding door moves to the opposite direction in foreign matter position, from this, can effectively avoid the foreign matter, thereby realize preventing pressing from both sides the function, make drive current resume normal, and need not to set up and prevent pressing from both sides the strip, the whole car cost has been reduced, prevent that the foreign matter from damaging electronic sliding door simultaneously, influence the life of electronic sliding door, the security and the reliability of electronic sliding door improve. On the other hand, if the deviation of the driving current and the comparison current does not exceed the preset value, the deviation of the driving current and the comparison current is considered to be small, no foreign matter or abnormality exists, and the anti-pinch function is not triggered, namely no foreign matter blocks the electric sliding door from moving, possibly because parameters such as voltage are unstable or other factors slightly influence the current, the current is slightly changed, and at the moment, the electric sliding door is controlled to keep the current running direction and running state.

In one embodiment of the present invention, after controlling the electric sliding door to move in the direction opposite to the current moving direction, the method further includes: and sending out prompt information for indicating that foreign matters exist on the moving path of the electric sliding door.

Specifically, when the anti-pinch function is triggered and the situation that foreign matter blocking exists on the moving path of the electric sliding door is determined, the electric sliding door is controlled to move in the direction opposite to the current moving direction, and then prompt information is sent out and used for indicating that the foreign matter blocking exists on the current moving path of the electric sliding door and the electric sliding door cannot pass through the current moving path smoothly, so that a user is reminded of disposing the foreign matter in time, and if the foreign matter is removed, the follow-up smooth passing of the electric sliding door is ensured.

In one embodiment of the present invention, the operating current may be determined according to a vehicle body angle, i.e., a gradient, including: and inputting the gradient (namely the vehicle body angle) into a current query model to obtain a comparison current (namely the working current) corresponding to the gradient, wherein the current query model is obtained by pre-training according to a plurality of groups of corresponding relation data of different gradients and comparison currents.

Specifically, a large amount of corresponding relation data of different gradients and comparative currents are obtained in advance, and the corresponding relation data are input into a training model for training to obtain a corresponding relation model related to the gradients and the comparative currents, namely a current query model. And then, inputting the gradient of the position where the electric sliding door is located into the current query model, so that a comparison current corresponding to the gradient can be obtained, and then the comparison current and the working current of the electric sliding door under the gradient can be compared to obtain the difference value of the comparison current and the working current, so that the electric sliding door is controlled to move according to the difference value.

In one embodiment of the present invention, the operating current may be determined according to a vehicle body angle, i.e., a gradient, including: according to the gradient (namely the vehicle body angle), a gradient-current two-dimensional mapping table is inquired to obtain a comparison current (namely a working current) corresponding to the gradient, wherein the gradient-current two-dimensional mapping table is obtained by calibrating in advance according to a plurality of groups of corresponding relation data of different gradients and comparison currents.

Specifically, a large amount of corresponding relation data of different gradients and comparison currents are obtained in advance, the corresponding relation data are calibrated, and a two-bit relation mapping table about the gradients and the comparison currents, namely a two-dimensional gradient-current mapping table, is generated. And then, the slope of the position where the electric sliding door is located is input into a slope-current two-dimensional mapping table, so that a comparison current corresponding to the slope can be inquired and obtained, the comparison current can be compared with the working current of the electric sliding door under the slope to obtain a difference value of the comparison current and the working current, and the electric sliding door is controlled to move according to the difference value.

In one embodiment of the present invention, the operating current may be determined according to a vehicle body angle, i.e., a gradient, including: and determining a comparison current (namely the working current) corresponding to the gradient (namely the vehicle body angle) by point tracing on a gradient-current mapping curve, wherein the gradient-current mapping curve is obtained by pre-fitting according to a plurality of corresponding relation data points of different gradients and comparison currents.

Specifically, a large number of corresponding relationship data points of different gradients and comparative currents are obtained in advance, and point-tracing fitting is performed on the corresponding relationship data points to obtain a two-bit relationship mapping table, namely a gradient-current mapping curve, about the gradients and the comparative currents. Furthermore, a point corresponding to the gradient can be found on the gradient-current mapping curve, and then a comparison current corresponding to the gradient is determined by tracing the point, so that a comparison current corresponding to the gradient can be obtained, and then the comparison current and the working current of the electric sliding door under the gradient can be compared to obtain the difference value of the comparison current and the working current, so that the electric sliding door is controlled to move according to the difference value.

In summary, the embodiment of the present invention can implement the anomaly detection by detecting the variation of the driving current in the driving process of the electric sliding door. Because driving current is relevant with actuating system's load, during the load change, driving current or driving current curve also have certain fluctuation, and when appearing unusually, actuating system's load can produce the difference with normal during operation, can accurately detect through detecting this kind of difference size whether unusual appears in electronic sliding door, if there is the foreign matter on the door moving path, like sand, fallen leaves etc. or whether unusual etc. of driving system trouble appears, and then do benefit to the accurate control of realization to electronic sliding door, improve the security and the reliability of electronic sliding door, and then promote the life of electronic sliding door. Meanwhile, in order to eliminate the load change error of normal work of the driving system under different gradient angles, the normal work current of the electric sliding door under different gradient angles can be tested in advance and used as the contrast current under the angle, the gradient angle of the electric sliding door is determined according to the pitching angle of a vehicle during normal work, and then the contrast current corresponding to the angle is selected for use, so that the current monitoring under different gradient angles is realized, the accuracy of abnormal detection is improved, and the accurate control of the electric sliding door is facilitated. Furthermore, when the electric sliding door is in an abnormal state, prompt can be timely carried out through a vehicle machine or a user terminal and the like, and convenience is brought to users to timely dispose and overhaul.

It should be noted that, the specific structure of the electric sliding door, the driving structure thereof, and the driving method thereof in the embodiment of the present invention are all known technologies in the art, for example, the vehicle door controller of the electric sliding door is used to control the driving mechanism (such as the driving motor) of the electric sliding door to operate, and further the driving mechanism is used to drive the electric sliding door to move.

Specifically, the preset value is a preset empirical value, which is set according to a magnitude indicating a deviation of the driving current from the contrast current. When the deviation between the driving current and the comparison current is larger than a preset value, the deviation between the driving current and the comparison current is considered to be larger, and at the moment, the electric sliding door is considered to be abnormal, namely, in an abnormal state, for example, a foreign object blocking or a driving system fault occurs on a moving path, so that the load of the driving system is changed, and the working current of the driving system is changed accordingly. On the other hand, if the deviation between the driving current and the comparison current does not exceed the preset value, the deviation between the driving current and the comparison current is considered to be small, and the electric sliding door is considered to have no abnormality, possibly because parameters such as voltage are unstable or other factors slightly influence the current, so that the current slightly changes.

Specifically, when the vehicle is not in a windy state, the wind power is small or no wind at the moment, the driving process of the electric sliding door is not influenced or the influence is small and negligible, the driving current is compared with the prestored working current, and when the absolute value of the difference value between the driving current and the prestored working current is greater than a preset value, it is determined that the electric sliding door is in an abnormal state, for example, a foreign object blockage or a driving system fault occurs on a moving path. At the moment, prompt information is generated and sent to remind a user that the electric sliding door is abnormal, and the electric sliding door should be overhauled and disposed in time, so that the safety and the reliability of the electric sliding door are improved, and the service life of the electric sliding door is prolonged.

Specifically, the driving current may include a driving current of the driving system at a certain time, or include a driving current of the driving system during a period of time, i.e., a driving current curve corresponding to the driving current during the period of time, and accordingly, the operating current, i.e., the comparison current, also includes a comparison current of the driving system at a certain time, or include a comparison current of the driving system during a period of time, i.e., a current curve corresponding to the comparison current during the period of time, i.e., a comparison current curve. Further, determining a difference between the drive current and the reference current comprises: comparing the driving current of the driving system at a certain moment with the comparison current at the corresponding moment, and determining the difference value of the driving current and the comparison current at the certain moment, or comparing the driving current curve of the driving system at a certain time with the comparison current curve at the corresponding time period, and determining the deviation between the driving current curve at the certain time and the comparison current curve.

Furthermore, the driving current of the electric sliding door in the driving process is related to the load of the driving motor, when the load changes, the driving current or the driving current curve can fluctuate to some extent, when an anti-pinch scene appears, namely, when the electric sliding door is abnormal, the load of the driving system can change along with the electric sliding door, at the moment, the load of the driving system can be different from that of the driving system in normal work, and the situation that whether the electric sliding door is abnormal or not can be accurately judged by detecting the difference, such as the situation that foreign matter blocking or driving system faults appear on a moving path. Therefore, when an abnormality occurs in the driving process of the electric sliding door, the load of the driving system changes, and at the moment, the driving current changes, such as becomes larger or smaller, so that a certain difference value is generated with the normal working current of the driving system before the load changes, namely when no abnormality occurs, whether the abnormality exists is detected according to the difference value, and the electric sliding door can be controlled to move. Generally, when the electric sliding door is abnormal, the driving current is greatly deviated from the current in normal operation, and therefore, when the deviation between the driving current of the electric sliding door and the contrast current is large, it is determined that the electric sliding door is abnormal, that is, in an abnormal state. Further, when the abnormity appears, the moving direction of the electric sliding door can be controlled, for example, the electric sliding door is controlled to move in the opposite direction, so that the anti-pinch function is realized, an anti-pinch strip is not required to be arranged, the cost of the whole vehicle is reduced, meanwhile, the electric sliding door is prevented from being damaged due to the abnormity, the service life of the electric sliding door is influenced, and the safety and the reliability of the electric sliding door are improved.

In an embodiment of the present invention, the determining module 130 further includes a controller, and after determining that the electric sliding door is in the abnormal state, the controller is further configured to: and controlling the electric sliding door to move towards the direction opposite to the current moving direction until the electric sliding door is in a fully-opened state or a fully-closed state.

Specifically, when the deviation between the driving current and the comparison current is greater than a preset value, the deviation between the driving current and the comparison current is considered to be large, at this time, the electric sliding door is considered to be abnormal and is in an abnormal state, if foreign matters exist on a moving path, an anti-pinch function is triggered, namely the foreign matters block the electric sliding door from moving, so that the load of the driving system is changed, and the working current of the driving system is changed accordingly. Under this condition, control electronic sliding door moves towards the direction opposite with the current direction of movement, until being in full open mode or full cut-off state, that is, control electronic sliding door moves to the opposite direction in foreign matter position, from this, can effectively avoid the foreign matter, thereby realize preventing pressing from both sides the function, make drive current resume normal, and need not to set up and prevent pressing from both sides the strip, the whole car cost has been reduced, prevent that the foreign matter from damaging electronic sliding door simultaneously, influence the life of electronic sliding door, the security and the reliability of electronic sliding door improve. On the other hand, if the deviation between the driving current and the comparison current does not exceed the preset value, the deviation between the driving current and the comparison current is considered to be small, no foreign matter or abnormality exists, and the anti-pinch function is not triggered, namely no foreign matter blocks the electric sliding door from moving.

In an embodiment of the present invention, after controlling the power sliding door to move in a direction opposite to the current moving direction, the prompting module 140 is further configured to: and sending out prompt information for indicating that foreign matters exist on the moving path of the electric sliding door.

Specifically, when the anti-pinch function is triggered and it is determined that foreign matter is blocked on the moving path of the electric sliding door, the electric sliding door is controlled to move in the direction opposite to the current moving direction, and then prompt information is sent, wherein the prompt information is used for indicating that the foreign matter is blocked on the current moving path of the electric sliding door and cannot pass through the electric sliding door smoothly, so that a user is timely reminded of handling the foreign matter, and if the foreign matter is removed, the follow-up smooth passing of the electric sliding door is ensured.

In one embodiment of the present invention, the operating current may be determined according to a vehicle body angle, i.e., a gradient, including: according to the gradient (namely the angle of the vehicle body), a gradient-current two-dimensional mapping table is inquired to obtain a comparison current (namely a working current) corresponding to the gradient, wherein the gradient-current two-dimensional mapping table is obtained by calibrating in advance according to a plurality of groups of corresponding relation data of different gradients and comparison currents.

In one embodiment of the present invention, the operating current may be determined according to a vehicle body angle, i.e., a gradient, including: a comparison current (i.e., an operating current) corresponding to a gradient (i.e., a vehicle body angle) is determined by plotting points on a gradient-current mapping curve, wherein the gradient-current mapping curve is pre-fitted according to a plurality of different gradient and comparison current correspondence data points.

Specifically, a large number of corresponding relationship data points of different slopes and contrast currents are obtained in advance, point-to-point fitting is performed on the corresponding relationship data points, and a two-bit relationship mapping table, namely a slope-current mapping curve, about the slopes and the contrast currents is obtained. Furthermore, a point corresponding to the gradient can be found on the gradient-current mapping curve, and then a comparison current corresponding to the gradient is determined by point drawing, so that a comparison current corresponding to the gradient can be obtained, and then the comparison current can be compared with the working current of the electric sliding door under the gradient to obtain a difference value of the comparison current and the working current, so that the electric sliding door is controlled to move according to the difference value.

Meanwhile, in order to eliminate the load change error of normal work of the driving system under different gradient angles, the normal working current of the electric sliding door under different gradient angles can be tested in advance, and the normal working current is used as the contrast current under the angle, the gradient angle of the electric sliding door is determined according to the pitching angle of the vehicle during normal work, and then the contrast current corresponding to the angle is selected for use, so that the current monitoring under different gradient angles is realized, the accuracy of abnormal detection is improved, and the accurate control of the electric sliding door is facilitated. Furthermore, when the electric sliding door is in an abnormal state, prompt can be timely carried out through a vehicle machine or a user terminal and the like, and convenience is brought to users to timely dispose and overhaul.
