The following describes in detail a method and apparatus for detecting an abnormal control command according to embodiments of the present application with reference to the accompanying drawings.
Fig. 1 is a schematic flow chart of a control method of a sunshade according to an embodiment of the present application, where an execution body of the control method may be a processor or a controller of a target vehicle. Referring to fig. 1, the method includes:
and 101, acquiring path information of a path navigated by a target vehicle and target illumination intensity in the target vehicle, wherein the path information comprises at least one of road section information of a hard road section and road section information of a shading road section.
The path information may also include the origin and destination of the navigated path.
Specifically, the road section information of the hard road section may include a start position and an end position of the hard road section, and the road section information of the light shielding road section may include a start position and an end position of the light shielding road section.
The hard road section is a road section with illumination intensity larger than a preset threshold value, and the shading road section is a road section with illumination intensity smaller than the preset threshold value.
The hard road section is usually a road section above a road without shielding, such as an expressway, an open urban road, and the like. The shade segments are typically segments over which a shade is present, such as tree-shaded mountain roads, tunnels, building-shaded urban roads, etc.
In addition, the embodiment can divide the navigated path into the hard light road section or the shading road section or into the hard light road section and the shading road section in advance according to the illumination intensity in the path, so that the target vehicle can determine which section of the path has stronger illumination intensity and which section of the path has weaker illumination intensity when acquiring the navigated path.
When the navigated path is divided into a plurality of road sections according to the illumination intensity, the illumination intensity can be detected through an illumination intensity sensor installed on the data acquisition vehicle under the condition of sufficient sunlight, the illumination intensity value of each position is obtained, the road sections with the illumination intensity value larger than the preset threshold value are determined to be hard road sections, and the road sections with the illumination intensity value smaller than the preset threshold value are determined to be shading road sections. The preset threshold may be a threshold set by the system or a user-defined threshold, for example, the preset threshold may be 500 lux, 600 lux, or the like.
In addition, the acquired path information can be uploaded to a cloud database, so that a controller of the target vehicle can inquire the path information of the navigated path from the cloud database.
In addition, when the path information of the path navigated by the target vehicle is acquired, the controller can also acquire the type of the road section in the navigated path and determine the road section information according to the type of the road section, wherein the type of the road section comprises an urban road, an expressway, a forest mountain road, a building-blocked urban road and the like, the urban road and the expressway are hard road sections, and the forest mountain road and the building-blocked urban road are light-shielding road sections.
In addition, the target illumination intensity is real-time illumination intensity in the vehicle during running of the vehicle, the embodiment CAN detect the target illumination intensity in the vehicle in real time through a sunlight intensity sensor installed in the target vehicle, and the sunlight intensity sensor sends the detected target illumination intensity to a controller through a controller area network (Controller Area Network, CAN) for being used as reference information for judging whether to close the sunshade curtain.
The path information of the path navigated by the target vehicle and the target illumination intensity in the target vehicle are obtained, so that the target vehicle can clearly determine the current in-vehicle environment and driving scene, and reference information is provided for subsequently controlling the opening and closing state of the sunshade curtain.
And 102, determining the road section type of the road section where the target vehicle is currently located according to the path information, wherein the road section type is a hard road section or a shading road section.
Specifically, since the path information includes at least one of the road section information of the highlight road section and the road section information of the shade road section, whether the road section type of the road section where the target vehicle is located is the highlight road section or the shade road section can be determined according to the path information, and thus the current driving scene of the target vehicle can be clarified.
And step 103, controlling the opening and closing states of the sunshade according to the target illumination intensity and the road section type.
The open and closed states of the sunshade include an open state or a closed state.
The sunshade curtain is judged to be closed or opened currently by the road section type of the road section where the target vehicle is located and the target illumination intensity in the target vehicle, so that the intelligent control of the sunshade curtain switch according to the environment in the vehicle and the driving scene is realized, the switch of the sunshade curtain is ensured to meet the requirements of users, the problem that the sunshade curtain switch is not timely due to the fact that the user needs to manually control the sunshade curtain in the related art is avoided, the problem that the user is waken or sun-damaged when resting due to the change of the external environment is effectively avoided, the driving hidden trouble caused by the operation of the sunshade curtain in the driving process is avoided, and the safety and the comfort in the driving process are improved.
In some embodiments, controlling the opening and closing states of the sunshade according to the target illumination intensity and the road section type includes:
determining an illumination type according to the target illumination intensity and a preset first illumination intensity threshold, wherein the illumination type comprises strong light illumination or weak light illumination, the strong light illumination refers to the target illumination intensity being greater than or equal to the first illumination intensity threshold, and the weak light illumination refers to the target illumination intensity being less than the first illumination intensity threshold; and controlling the opening and closing states of the sunshade according to the illumination type and the road section type.
Specifically, the illumination type includes strong light illumination and weak light illumination, and the illumination type is strong light illumination when the target illumination intensity is greater than or equal to the first illumination intensity threshold value, and weak light illumination when the target illumination intensity is less than the first illumination intensity threshold value.
The first illumination intensity threshold may be set according to a human body feel, for example, the first illumination intensity threshold may be an illumination intensity comfortable to the human body feel, and as an example, the illumination intensity comfortable to the human body feel may range from 300 lux to 500 lux. In addition, it should be noted that the first illumination intensity threshold may be preset by the system or user-defined, for example, the first illumination threshold may be set to 400 lux or 500 lux.
In this embodiment, the controller determines the illumination type of the position where the target vehicle is located through the target illumination intensity and the preset first illumination intensity threshold value, so that specific target illumination intensity data are mapped into categories, and discretization of the target illumination intensity is realized, and therefore, when the opening and closing states of the sunshade curtain are controlled according to the illumination type and the road section type, the calculation process for controlling the sunshade curtain is simplified.
In some embodiments, controlling the opening and closing states of the sunshade according to the illumination type and the road section type comprises at least one of the following:
the method comprises the following steps: under the condition that the illumination type is strong illumination, if the road section type is a shading road section and the illumination type is continuously strong illumination in a preset period, or if the road section type is a strong road section and the length of the rest road section of the strong road section is greater than or equal to a first preset length, the sunshade curtain is controlled to be closed.
The preset period may be a time for continuously detecting the target illumination intensity while the light-shielding section, and as one example, the preset period may be 3 seconds, 5 seconds, or the like, which is not particularly limited herein. The first preset length may be preset by the controller or user-defined, and as an example, the first preset length may be 30 meters, 50 meters, etc.
If the sun shade is currently under strong light irradiation and is in a shading road section, if the light type is continuously under strong light irradiation within a preset period of time, the current sunlight intensity CAN be judged to be too high, and the shading road section is the shading road section, but still the sun shade needs to be closed to reduce the sunlight intensity, at the moment, the controller CAN send a closing instruction to an electronic control unit (Electronic Control Unit, ECU) of the sun shade through a CAN bus so as to be used for indicating the closing of the sun shade; and after receiving the closing instruction, the ECU executes the operation of closing the sunshade curtain, and the sunshade curtain is closed.
If the current state of the sunshade curtain is an open state, the ECU of the sunshade curtain executes a closing instruction; if the current state of the shade is a closed state, the ECU of the shade may no longer execute the closing instruction or repeatedly execute the closing instruction. That is, the present embodiment only needs to ensure that the state of the sunshade curtain is the closed state in this scene.
In addition, if the current strong light irradiation is performed and the current strong light road section is in the strong light road section, the remaining degree of the current strong light road section can be determined based on the road section information, and if the remaining road section length of the current strong light road section is greater than or equal to the first preset length, the condition that the current strong light road section is subjected to the strong light irradiation for a long time is indicated, and at the moment, the sunshade curtain can be controlled to be closed. If the remaining road segment length of the current hard road segment is smaller than the first preset length, the sunshade curtain is not required to be closed until the target vehicle reaches the next road segment, and then re-detection is performed.
It should be noted that, for each road section, the switch state of the sunshade curtain can be controlled according to the illumination type and the road section type, so as to realize the cycle detection of each road section.
And two,: under the condition that the illumination type is dim light illumination, if the road section type is a hard road section and the target vehicle is currently in a preset range of the starting position of the hard road section, or if the road section type is a shading road section and the remaining road section length of the shading road section is greater than a second preset length, opening the sunshade curtain is controlled.
Specifically, the second preset length may be preset by the controller or user-defined, and as an example, the second preset length may be 50 meters, 70 meters, or the like.
If the vehicle is currently under low-light irradiation and is in a strong-light road section, if the target vehicle is in a preset range at the initial position of the strong-light road section, the current sunlight intensity can be indicated to be weak, and the low-light irradiation can be still required to last for a long time as the target vehicle just enters the strong-light road section, so that the sunshade curtain can be controlled to be opened. The preset range may be set according to actual requirements, for example, may be set to 3 meters, 5 meters, and the like.
If the current light-shielding road section is under low-light irradiation and is in a light-shielding road section, the remaining degree of the current light-shielding road section can be determined based on the road section information, and if the remaining road section length of the current light-shielding road section is greater than or equal to a second preset length, the current light-shielding road section is indicated to be subjected to low-light irradiation for a longer time, and the opening of the sunshade curtain can be controlled. Of course, if the remaining road section length of the current shading road section is smaller than the second preset length, the current illumination intensity can only affect the driver in a short time, and the opening operation of the sunshade curtain can not be executed until the target vehicle reaches the next road section, and then re-detection is performed.
It should be noted that, the controller may receive feedback given by the user for automatically closing the sunshade, and if it is detected that the user manually opens the sunshade after the sunshade is closed, the controller does not control the opening and closing state of the sunshade; if the fact that the user does not manually open the sunshade after the sunshade is closed is detected, the opening and closing states of the sunshade are continuously controlled.
The embodiment realizes the automatic control of the opening and closing state of the sunshade curtain by combining the illumination environment and the driving scene, and improves the comfort and convenience of driving.
The process of closing the sunshade in the present application will be described with reference to fig. 2.
As shown in fig. 2, assuming that the current state of the sunshade is an open state, sunlight can be injected into the vehicle through the window, and the closing process of the sunshade includes the steps of:
in step 201, a sunlight intensity sensor obtains a current target illumination intensity.
Step 202, the sunlight intensity sensor sends the target illumination intensity to the controller through the CAN bus.
In step 203, the controller determines whether the target illumination intensity is greater than a first illumination intensity threshold.
After the controller receives the target illumination intensity, the target illumination intensity can be compared with a preset first illumination intensity threshold value, and whether the target illumination intensity is larger than the first illumination intensity threshold value is judged.
And 204, if the current illumination type is larger than the current illumination type, determining that the current illumination type is strong illumination.
And if the target illumination intensity is greater than or equal to the first illumination intensity threshold, determining that the illumination is strong light, if the target illumination intensity is less than the first illumination intensity threshold, determining that the illumination is weak light, comparing the acquired target illumination intensity with the first illumination intensity threshold again, and judging whether the target illumination intensity is greater than the first illumination intensity threshold.
And step 205, the controller sends a closing instruction to the ECU of the sunshade curtain through the CAN bus.
In particular, the close command is used to instruct to close the sunshade. If the current illumination type is strong illumination, if the current road section type is a shading road section and the illumination type is continuously strong illumination within a preset period, or if the road section type is a strong road section and the remaining road section length of the strong road section is greater than or equal to a first preset length, a closing instruction is sent to an ECU of the sunshade curtain.
And 206, after receiving the closing instruction, the ECU executes the closing instruction to close the sunshade curtain.
The automatic switching process of the window shade from the open state to the closed state is realized through the steps, the window shade is not manually operated by a user, and the problem of untimely closing of the window shade is avoided.
In addition, a first illumination intensity threshold needs to be set before determining the illumination type. How to set the first illumination intensity threshold is explained below.
In some embodiments, before determining the illumination type according to the target illumination intensity and the preset first illumination intensity threshold, the method further includes:
under the condition that a target user is included in the target vehicle, determining a first sunlight preference type corresponding to the target user according to a preset corresponding relation between a preset user and the sunlight preference type, and determining a first illumination intensity threshold according to the first sunlight preference type, wherein the sunlight preference type indicates sunlight illumination intensity preferred by the user;
under the condition that at least two target users are included in the target vehicle, determining a second sunlight preference type corresponding to each target user according to a preset corresponding relation between the preset users and the sunlight preference types; a target preference type is selected from the second sunlight preference types, and a first illumination intensity threshold is determined according to the target preference type, wherein the sunlight illumination intensity indicated by the target preference type is the lowest.
In particular, the target user may be a driver in the target vehicle or an occupant in the target vehicle.
In addition, the solar preference type indicates the solar radiation intensity preferred by different people or individuals of the user, for example, the solar preference type may include types of "special sun-proof", "normal", "sun-proof", "special sun-proof", and the like.
Users can preset the sunlight irradiation intensity preferred by the users in the controller of the target vehicle in modes of a vehicle central control screen, an Application (APP) and the like, and certainly, the controller can preset the sunlight preference types corresponding to different types of people, the people can be divided into different types based on the conditions of age groups, gender, skin and the like, so that the preset corresponding relation between different users and the sunlight preference types is maintained in the controller.
When only one target user exists in the target vehicle, the sunlight preference type of the target user can be determined directly according to the corresponding relation between the target user and the sunlight preference type, and the first illumination intensity threshold value is determined according to the sunlight preference type. Specifically, when the first illumination intensity threshold is determined according to the sunlight preference type, the first illumination intensity threshold may be determined according to an illumination intensity range corresponding to the sunlight preference type, for example, a median value in the illumination intensity range is determined as the first illumination intensity threshold, or a minimum value in the illumination intensity range is determined as the first illumination intensity threshold.
When a plurality of target users exist in the target vehicle, face images of each target user can be acquired, each target user is identified according to the face images, and then a second sunlight preference type corresponding to each target user is determined; because the second sunlight preference types corresponding to different target users may be different, in order to ensure that all target users are not sunburned, the embodiment may select the target preference type with the lowest corresponding sunlight irradiation intensity, and determine the first illumination intensity threshold according to the target preference type, so that the determined illumination intensity threshold can meet the illumination requirements of all target users.
According to the technical scheme provided by the embodiment, the target vehicle can determine the first illumination intensity threshold according to the sunlight preference of different users, so that the opening and closing states of the sunshade curtain are controlled, the illumination type is determined by combining personalized sunlight preference settings, and the driving comfort level is improved.
The following describes the present embodiment with reference to fig. 3, and as shown in fig. 3, the setting process of the first illumination intensity threshold is as follows:
step 301, define a solar preference type.
As one example, the solar preference types may include "special sun-proof", "normal", "sun-proof", "special sun-proof", and the like types. For example, the embodiment may take the initial first illumination intensity threshold as a reference value, as a middle value of the illumination intensity range corresponding to the "normal" type, and set the illumination intensity ranges corresponding to the other sunlight preference types respectively according to the middle value. It should be noted that, the illumination intensity range corresponding to the sunlight preference type may be user-defined, or may be corrected according to the usage habit of the user during actual operation. For example, the intermediate value of the illumination intensity range corresponding to "extra sun-proof" is 300 lux, the intermediate value of the illumination intensity range corresponding to "sun-proof" is 400 lux, the intermediate value of the illumination intensity range corresponding to "normal" is 500 lux, the intermediate value of the illumination intensity range corresponding to "sun-proof" is 600 lux, and the intermediate value of the illumination intensity range corresponding to "extra sun-proof" is 700 lux.
In step 302, the user selects the sunlight preference type through a multimedia system interface, intelligent voice, APP and the like, and synchronizes the sunlight preference type to a cloud user identity (Identity document, ID).
In step 303, the user logs in to the user ID via a driver detection system (Driver Monitor System, DMS) or a multimedia system after getting on the vehicle.
Step 304, after the user ID logs in, the cloud end issues a sunlight preference type corresponding to the user ID to the target vehicle.
Step 305, combining the sunlight preference type, adjusting to obtain a first illumination intensity threshold value corresponding to the sunlight preference type, and controlling the opening and closing state of the sunshade curtain.
Therefore, the first illumination intensity threshold value is set by combining the personalized sunlight preference type through the process, the opening and closing states of the sunshade curtain are controlled, and riding comfort of passengers in the automobile is improved.
In addition, the first illumination intensity threshold value can be updated according to seasons or conditions of passengers in the vehicle. This will be described below.
In some embodiments, determining the illumination type according to the target illumination intensity and a preset first illumination intensity threshold value comprises:
updating the first illumination intensity threshold according to the corresponding relation between seasons and the first illumination intensity threshold and the target season to which the current date belongs to obtain a second illumination intensity threshold; and determining the illumination type according to the target illumination intensity and the second illumination intensity threshold.
Specifically, the target season is any season among four seasons of spring, summer, autumn and east.
The corresponding relation between the season and the first illumination intensity threshold value can be preset, for example, when the season is spring or autumn, the second illumination intensity threshold value can be the same as the first illumination intensity threshold value; the second illumination intensity threshold may be less than the first illumination intensity threshold when the season is summer, e.g., the first illumination intensity threshold with the second illumination intensity threshold being 0.9 times; when the season is winter, the second illumination threshold may be greater than the first illumination intensity threshold, e.g., the first illumination intensity threshold with the second illumination intensity threshold being 1.1 times.
After the target vehicle determines the target season to which the current date belongs, the first illumination intensity threshold value can be updated according to the corresponding relation to obtain the second illumination intensity threshold value, so that the illumination intensity threshold value is updated by fully considering the seasonal variable, and the opening and closing of the sunshade curtain are controlled, and the opening and closing of the sunshade curtain are more in accordance with the actual situation.
In addition, when the illumination type is determined according to the target illumination intensity and the second illumination intensity threshold, the illumination type may be strong illumination when the target illumination intensity is greater than or equal to the second illumination intensity threshold, and weak illumination when the target illumination intensity is less than the second illumination intensity threshold.
The following describes the present embodiment with reference to fig. 4, and as shown in fig. 4, the updating process of the first illumination intensity threshold is as follows:
