A method, apparatus, vehicle and computer readable storage medium for monitoring the performance of an electric sliding door according to an embodiment of the present invention are described below with reference to fig. 1-2.
The electric sliding door is one of high-end functions currently applied to automobiles. When the electric sliding door technology is initially applied to automobiles, the electric sliding door technology is mainly assembled in high-end vehicles, and high-end experiences brought by the electric sliding door technology also conquer a plurality of automobile owners. However, as the application of the electric sliding door is becoming more popular, the feedback of the problem of the electric sliding door is also increasing, 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 service time of the electric sliding door is shortened. The application aims to improve the quality of application of the electric sliding door on a vehicle and prolong the service life of the electric sliding door.
Fig. 1 is a flowchart of a method of monitoring performance of an electric sliding door according to one embodiment of the 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 an electric sliding door driving instruction, and calling the vehicle state in response to the driving instruction.
Specifically, the electric sliding door driving instruction is instruction information for instructing a driving system for controlling the electric sliding door to drive the electric sliding door to move. The driving instruction of the electric sliding door can be sent by a user through a switch key outside the door or through a user terminal and the like, and 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 driving instruction is responded, the vehicle state, such as the current body angle of the vehicle and the wind-receiving state of the vehicle, such as whether the vehicle receives wind or not, is called. The vehicle body angle is the gradient of the vehicle.
Step S2: and acquiring the driving current in the driving process of the electric sliding door in real time.
Specifically, after receiving an electric sliding door driving instruction, 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 driving current of the electric sliding door in the driving process is obtained. In a specific embodiment, the driving current in the driving process of the electric sliding door can be obtained through a current sensor. When the electric sliding door moves, the motor of the driving system is in a working state, and at the moment, the driving current of the driving system can be obtained through the current sensor. Or, the operating parameters such as the operating voltage and the 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 the driving current of the driving system at a certain moment, or include the driving current of the driving system in a period of time, where the driving current is a current curve corresponding to the driving current of the driving system in the period of time, that is, a driving current curve.
Step S3: and judging whether the electric sliding door is in an abnormal state according to the vehicle state and the driving current. That is, whether the electric sliding door is in an abnormal state is comprehensively judged by combining information such as a vehicle body angle, a wind-receiving state and the like of the vehicle and driving current, and therefore, the influence of the vehicle state on the driving current is considered, the accuracy of detecting the abnormal state is improved, and when the electric sliding door is abnormal, accurate prompt and early warning information is 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 prolonged.
Step S4: if yes, generating prompt information. Namely, when the electric sliding door is judged to be in an abnormal state, prompt and early warning information is sent out, so that the safety and reliability of the electric sliding door are improved, and the service life of the electric sliding door is prolonged.
In a specific embodiment, at least one of the voice prompt information and the light prompt information can be sent out, so that the reliability of the alarm prompt is improved.
Therefore, according to the electric sliding door performance monitoring method, the driving instruction of the electric sliding door is obtained, the vehicle state is called in response to the driving instruction, the driving current in the driving process of the electric sliding door is obtained in real time, whether the electric sliding door is in an abnormal state or not is judged according to the vehicle state and the driving current, and if so, prompt information is generated. 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 prompt information is sent out when the electric sliding door is judged to be abnormal, so that the driving process of the electric sliding door can be monitored in real time and warned for prompt, the safety and reliability of the electric sliding door are improved, the service life of the electric sliding door is prolonged, the influence of the vehicle state on the driving current is considered, and the accuracy of abnormal state detection is improved.
In one embodiment of the invention, the vehicle conditions include at least a body angle and a windup condition. The vehicle body angle is, for example, the gradient of the vehicle, and the wind-receiving state is used for indicating whether the vehicle is receiving wind, the wind force and direction and other information.
In one embodiment of the present invention, in step S3, determining whether the electric sliding door is in an abnormal state according to the vehicle state and the driving current includes: when the vehicle is not in the windy state, if the absolute value of the difference value between the driving current and the pre-stored working current is larger than the preset value, the electric sliding door is judged to be in an abnormal state.
Specifically, the preset value is an empirical value set in advance, and is set according to the magnitude of deviation between the drive current and the reference current. When the deviation between the driving current and the comparison current is larger than a preset value, the deviation between the driving action 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, such as the occurrence of foreign matter blocking or driving system faults 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, it is considered that the deviation between the driving current and the comparison current is small, and it is considered that the electric sliding door is not abnormal, possibly because parameters such as voltage are unstable or other factors slightly influence the current, so that the current is slightly changed.
Specifically, when the vehicle is not in a windy state, the wind force is very small or no, the driving process of the electric sliding door is not influenced or is very little influenced to be negligible, the driving current is compared with the pre-stored working current, and when the absolute value of the difference value of the driving current and the pre-stored working current is larger than a preset value, the electric sliding door is judged to be in an abnormal state, such as foreign matter blocking or driving system faults and the like on a moving path. At this time, the prompt message is generated and sent out to remind the 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.
In particular, the driving current may comprise a driving current of the driving system at a certain moment, or comprise a driving current of the driving system over a period of time, i.e. a driving current curve corresponding to the driving current during the period of time, and the corresponding working current, i.e. the contrast current, also corresponds to a contrast current comprising the driving system at a certain moment, or comprise a contrast current of the driving system over a period of time, i.e. a current curve corresponding to the contrast current during the period of time, i.e. a contrast current curve. Further, determining the difference between the drive current and the contrast current, i.e. comprising: and comparing the driving current of the driving system at a certain moment with the comparison current at a corresponding moment to determine the difference value between the driving current at a certain moment and the comparison current, or comparing the driving current curve of the driving system at a certain time with the comparison current curve of a corresponding time period to determine the deviation between the driving current curve at a certain time and the comparison current curve.
Further, 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 also has certain fluctuation, and when the anti-pinch scene appears, namely, the electric sliding door is abnormal, the load of the driving system changes along with the driving current, at the moment, the load of the driving system and the normal working of the driving system can generate difference, and whether the electric sliding door is abnormal or not can be accurately judged by detecting the difference, such as foreign matter blocking or driving system faults 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 between the driving current and the normal working current of the driving system before the load changes, namely, when no abnormality occurs, whether the abnormality exists or not is detected according to the difference value, and the movement of the electric sliding door can be controlled. Generally, when an electric sliding door is abnormal, the driving current will deviate from the current in normal operation, so when the driving current of the electric sliding door deviates from the comparison current greatly, the electric sliding door is judged to be abnormal, namely in an abnormal state. Further, when the abnormality occurs, 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-clamping function is realized, the anti-clamping strip is not required to be arranged, the cost of the whole automobile is reduced, the electric sliding door is prevented from being damaged due to the abnormality, 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 vehicle body angles when the vehicle is not in a windy state.
Specifically, when the vehicle is not in a windy state, the load of the electric sliding door is changed differently under different gradients due to the gravity component, so that the deviation between the driving current and the normal working current is also different under different gradients. Therefore, in order to eliminate the load change of the normal work of the driving motor under different gradients, the normal working current of the electric sliding door under different angles can be tested in advance, and the normal working current is used as the comparison current under the angle, and different comparison currents are selected according to the pitching angle of the vehicle during normal work, so that the current anti-pinch under different angles is realized. That is, the electric sliding door is correspondingly obtained by testing different working currents, namely comparison currents, in advance under different gradient angles. Before determining the difference value of the working current and the contrast current, firstly determining that the vehicle is not in a windy state, acquiring the gradient angle of the position where the electric sliding door is located, and selecting the contrast current of the driving motor corresponding to the gradient angle according to the gradient angle, thereby enabling the working current and the contrast current to be under the working condition of the same gradient angle, eliminating the difference value error caused by different gradient angles, improving the accuracy of the difference value, and further being beneficial to improving the control accuracy of the electric sliding door.
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 in 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 larger than a preset value, the deviation between the driving current and the comparison current is considered to be larger, at the moment, 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-clamping function is triggered, namely, the foreign matters block the electric sliding door to move, so that the load of the driving system is changed, and the working current of the driving system is changed accordingly. Under the condition, the electric sliding door is controlled to move in the direction opposite to the current moving direction until the electric sliding door is in a fully opened state or a fully closed state, namely, the electric sliding door is controlled to move in the direction opposite to the position of the foreign matter, so that the foreign matter can be effectively avoided, the anti-clamping function is realized, the driving current is restored to be normal, an anti-clamping strip is not required to be arranged, the cost of the whole vehicle is reduced, the foreign matter is prevented from damaging the electric sliding door, the service life of the electric sliding door is influenced, and the safety and the reliability of the electric sliding door are improved. 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 smaller, the foreign matter or abnormality is considered to be absent, the anti-pinch function is not triggered, that is, the foreign matter does not block the movement of the electric sliding door, and the current is slightly changed due to unstable parameters such as voltage or the like or slight influence of other factors on the current, and at this time, 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 a direction opposite to the current moving direction, the method further comprises: 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 foreign matter blocking exists 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 out, wherein the prompt information is used for indicating that the electric sliding door has foreign matter blocking on the current moving path and cannot pass smoothly, so that a user is timely reminded of handling, such as removing the foreign matter, and the subsequent smooth passing of the electric sliding door is ensured.
In one embodiment of the present invention, the operating current may be determined based on the vehicle body angle, i.e., grade, 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 training in advance according to a plurality of groups of corresponding relation data of different gradients and the comparison current.
Specifically, a large amount of corresponding relation data of different gradients and comparison currents are obtained in advance, and are input into a training model for training, so that a corresponding relation model, namely a current query model, of the gradients and the comparison currents is obtained. And then, inputting the gradient of the position of the electric sliding door into a current inquiry model to obtain a comparison current corresponding to the gradient, and further comparing the comparison current 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 of the electric sliding door under the gradient, and further controlling the electric sliding door to move according to the difference value.
In one embodiment of the present invention, the operating current may be determined based on the vehicle body angle, i.e., grade, including: and obtaining a comparison current (namely working current) corresponding to the gradient by inquiring a gradient-current two-dimensional mapping table according to the gradient (namely the vehicle body angle), 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 the comparison current.
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-position relation mapping table, namely a gradient-current two-dimensional mapping table, is generated. And then, inputting the gradient of the position of the electric sliding door into a gradient-current two-dimensional mapping table, and inquiring to obtain a comparison current corresponding to the gradient, so that 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, and further, the movement of the electric sliding door is controlled according to the difference value.

Specifically, after receiving an electric sliding door driving instruction, 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 driving current of the electric sliding door in the driving process is obtained. In a specific embodiment, the driving current in the driving process of the electric sliding door can be obtained through a current sensor. When the electric sliding door moves, the motor of the driving system is in a working state, and at the moment, the driving current of the driving system can be obtained through the current sensor. Or, the operating parameters such as the operating voltage and the 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 the driving current of the driving system at a certain moment, or include the driving current of the driving system in a period of time, where the driving current is a current curve corresponding to the driving current of the driving system in the period of time, that is, a driving current curve.
The judging module 130 is configured to judge whether the electric sliding door is in an abnormal state according to the vehicle state and the driving current. That is, whether the electric sliding door is in an abnormal state is comprehensively judged by combining information such as a vehicle body angle, a wind-receiving state and the like of the vehicle and driving current, and therefore, the influence of the vehicle state on the driving current is considered, the accuracy of detecting the abnormal state is improved, and when the electric sliding door is abnormal, accurate prompt and early warning information is 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 prolonged.
The prompt module 140 is configured to generate prompt information when the electric sliding door is in an abnormal state, thereby improving safety and reliability of the electric sliding door, and facilitating improvement of service life of the electric sliding door.
In a specific embodiment, the prompting module 140 can send out at least one of the voice prompting information and the light prompting information, so as to improve the reliability of the alarm prompting.
Therefore, the electric sliding door performance monitoring device 100 acquires the driving command of the electric sliding door, and responds to the driving command to retrieve the vehicle state, 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 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 prompt information is sent out when the electric sliding door is judged to be abnormal, so that the driving process of the electric sliding door can be monitored in real time and warned for prompt, the safety and reliability of the electric sliding door are improved, the service life of the electric sliding door is prolonged, the influence of the vehicle state on the driving current is considered, and the accuracy of abnormal state detection is improved.
In one embodiment of the invention, the vehicle conditions include at least a body angle and a windup condition. The vehicle body angle is, for example, the gradient of the vehicle, and the wind-receiving state is used for indicating whether the vehicle is receiving wind, the wind force and direction and other information.
In one embodiment of the present invention, the determining module 130 determines whether the electric sliding door is in an abnormal state according to the vehicle state and the driving current includes: when the vehicle is not in the windy state, if the absolute value of the difference value between the driving current and the pre-stored working current is larger than the preset value, the electric sliding door is judged to be in an abnormal state.
Specifically, the preset value is an empirical value set in advance, and is set according to the magnitude of deviation between the drive current and the reference current. When the deviation between the driving current and the comparison current is larger than a preset value, the deviation between the driving action 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, such as the occurrence of foreign matter blocking or driving system faults 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, it is considered that the deviation between the driving current and the comparison current is small, and it is considered that the electric sliding door is not abnormal, possibly because parameters such as voltage are unstable or other factors slightly influence the current, so that the current is slightly changed.
Specifically, when the vehicle is not in a windy state, the wind force is very small or no, the driving process of the electric sliding door is not influenced or is very little influenced to be negligible, the driving current is compared with the pre-stored working current, and when the absolute value of the difference value of the driving current and the pre-stored working current is larger than a preset value, the electric sliding door is judged to be in an abnormal state, such as foreign matter blocking or driving system faults and the like on a moving path. At this time, the prompt message is generated and sent out to remind the 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.
In particular, the driving current may comprise a driving current of the driving system at a certain moment, or comprise a driving current of the driving system over a period of time, i.e. a driving current curve corresponding to the driving current during the period of time, and the corresponding working current, i.e. the contrast current, also corresponds to a contrast current comprising the driving system at a certain moment, or comprise a contrast current of the driving system over a period of time, i.e. a current curve corresponding to the contrast current during the period of time, i.e. a contrast current curve. Further, determining the difference between the drive current and the contrast current, i.e. comprising: and comparing the driving current of the driving system at a certain moment with the comparison current at a corresponding moment to determine the difference value between the driving current at a certain moment and the comparison current, or comparing the driving current curve of the driving system at a certain time with the comparison current curve of a corresponding time period to determine the deviation between the driving current curve at a certain time and the comparison current curve.
Further, 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 also has certain fluctuation, and when the anti-pinch scene appears, namely, the electric sliding door is abnormal, the load of the driving system changes along with the driving current, at the moment, the load of the driving system and the normal working of the driving system can generate difference, and whether the electric sliding door is abnormal or not can be accurately judged by detecting the difference, such as foreign matter blocking or driving system faults 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 between the driving current and the normal working current of the driving system before the load changes, namely, when no abnormality occurs, whether the abnormality exists or not is detected according to the difference value, and the movement of the electric sliding door can be controlled. Generally, when an electric sliding door is abnormal, the driving current will deviate from the current in normal operation, so when the driving current of the electric sliding door deviates from the comparison current greatly, the electric sliding door is judged to be abnormal, namely in an abnormal state. Further, when the abnormality occurs, 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-clamping function is realized, the anti-clamping strip is not required to be arranged, the cost of the whole automobile is reduced, the electric sliding door is prevented from being damaged due to the abnormality, the service life of the electric sliding door is influenced, and the safety and the reliability of the electric sliding door are improved.

Specifically, 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, at the moment, 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-clamping function is triggered, namely, the foreign matters block the electric sliding door to move, so that the load of the driving system is changed, and the working current of the driving system is changed accordingly. Under the condition, the electric sliding door is controlled to move in the direction opposite to the current moving direction until the electric sliding door is in a fully opened state or a fully closed state, namely, the electric sliding door is controlled to move in the direction opposite to the position of the foreign matter, so that the foreign matter can be effectively avoided, the anti-clamping function is realized, the driving current is restored to be normal, an anti-clamping strip is not required to be arranged, the cost of the whole vehicle is reduced, the foreign matter is prevented from damaging the electric sliding door, the service life of the electric sliding door is influenced, and the safety and the reliability of the electric sliding door are improved. 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 smaller, the foreign matter or abnormality is considered to be absent, the anti-pinch function is not triggered, that is, the foreign matter does not block the movement of the electric sliding door, and the current is slightly changed due to unstable parameters such as voltage or the like or slight influence of other factors on the current, and at this time, 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 a direction opposite to the current moving direction, the prompt 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 foreign matter blocking exists 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 out, wherein the prompt information is used for indicating that the electric sliding door has foreign matter blocking on the current moving path and cannot pass smoothly, so that a user is timely reminded of handling, such as removing the foreign matter, and the subsequent smooth passing of the electric sliding door is ensured.
