With rapid development of intellectualization of automobiles at present, intelligent control of automobile windows provides a user with window lifting control functions in various scenes, such as driver/passenger key control windows, vehicle-mounted telematics BOX (T-BOX) control windows, voice control windows, sensor key control windows, remote key control windows, bluetooth key control windows, mobile phone application control windows, off-car locking auto-closing windows, vehicle speed sensing auto-closing windows, parking state auto-closing windows, car washing auto-closing windows, one-key lifting windows, rain and snow mode auto-closing windows, intelligent rest mode auto-closing windows, and the like.
The window control instruction is numerous and complex, and sometimes the condition that the window is suddenly and automatically closed or suddenly and automatically opened is easy to cause user complaints, and after the user complaints are received, the reason of the fault needs to be determined as soon as possible so as to eliminate the fault.
However, since the window up and down command is transmitted in the form of an event frame on the bus, after receiving the window motion trigger event, the window motion trigger source will send the window up and down command to the window controller once through the bus, and send the window up and down command once again after a 50ms interval, for a total of 5 times, for a total of 250ms, and will clear the command after completion. The data transmission between the vehicle-mounted remote information processor and the data management background has a time interval, specifically, the data transmission time interval between the vehicle-mounted remote information processor and the data management background is 1s, that is, the vehicle-mounted remote information processor sends an instruction received by the vehicle window controller to the data management background every 1 s.
The vehicle-mounted remote information processor acquires instructions transmitted on the bus through the bus and uploads the acquired instructions to the data management background.
It should be noted that, the above-mentioned vehicle-mounted remote information processor is mainly used for the data management backstage, realize data record and control of data management backstage and vehicle. The data management background is mainly used for recording relevant data of vehicles, including relevant data of various states of the vehicles, relevant data of various instructions executed by the vehicles and the like. Because the data transmission time interval between the vehicle-mounted remote information processor and the data management background is longer than the sending time of the lifting instruction of the vehicle window on the bus, the situation that the lifting instruction of the vehicle window cannot be recorded exists in the data management background, and therefore the situation that the fault source cannot be positioned quickly after the user complains are received is caused.
Note that, the window action triggering sources include, but are not limited to: pulse width modulated signal (Pulse width modulation, PWM) sources, vehicle-mounted telematics BOX (T-BOX), voice control signal trigger sources, remote keyless entry (Remote Keyless Entry, RKE), passive keyless entry (Passive Keyless Entry, PKE), bluetooth, optical rainfall sensor (Rain Light Sensor, RLS), cell phone applications, off-vehicle latch signal sources, vehicle speed sensing auto-close window signal sources, parking status auto-close window, car wash auto-close window, one-key lift window, sleet mode auto-close window, intelligent rest mode auto-close window, "space-time door" mode auto-close window, and the like.
The PWM signal source may be generated by controlling the window to be lifted according to a driver/passenger button.
In order to enable a data management background to accurately record a window control instruction, the embodiment of the application provides a window control method, which is characterized in that after a window action triggering event is detected, the window control instruction of the window triggering event is kept in a window controller, and the window control instruction is continuously sent to a bus until a new window action triggering event is received, so that when the bus instruction is uploaded to the data management background, a vehicle-mounted remote information processor can acquire the window control instruction, and the data management background can record relevant information of the window control instruction.
Based on the method, when the fault complaint of the user is received, the fault source can be determined through the related information of the window control instruction recorded in the data management background, so that the efficiency and the accuracy of fault investigation are improved.
The application scenario to which the window control method provided in the embodiment of the present application is applicable is first described in the following example:
referring to fig. 1, fig. 1 shows an application scenario schematic diagram of a vehicle window control method provided in an embodiment of the present application. As shown in fig. 1, the vehicle may include a window controller 10 and an on-board telematics processor (T-BOX) 20, wherein the on-board telematics processor 20 is communicatively coupled to the window controller 10 via a CAN bus and the on-board telematics processor is communicatively coupled to a data management backend 30.
In the embodiment of the present application, the window controller has functions of data processing, data communication, program running, and the like, and may be an electronic control unit (Electronic Control Unit, ECU) of a vehicle, also referred to as a vehicle-mounted computer, or may be a device having the same or similar functions, which is not limited in this embodiment.
The window controller can receive the window control instruction sent by each window action triggering source and control the corresponding window to execute the action corresponding to the window control instruction so as to realize intelligent control of the window, and can send the related information of the window action triggering event to the bus, so that the vehicle-mounted remote information processor 20 can acquire the related information of the window action triggering event through the bus and upload the acquired related information of the window action triggering event to the data management background, the data management background is used for maintaining the data, and when an maintainer needs to inquire the data, the data recorded in the data management background can be inquired and analyzed so as to realize overhaul and maintenance of the vehicle.
An exemplary method for controlling a vehicle window according to an embodiment of the present application will be described below with reference to the accompanying drawings:
Referring to fig. 2, fig. 2 is a schematic implementation flow chart of a vehicle window control method according to an embodiment of the present application. In the embodiment of the present application, the execution body of the window control method may be a window controller.
S11: and when the vehicle window action triggering event is detected, acquiring the related information of the vehicle triggering event.
In this embodiment of the present application, the information about the window action triggering event may include a window action triggering source corresponding to the window action triggering event and a window control instruction corresponding to the window action triggering event.
Here, the window operation trigger source refers to an object that issues a window control command, which refers to what operation is performed by the window, and the window control command may include, but is not limited to, a window up control command and a window down control command. The window-up control command is used for controlling the window to be lifted up, and the window-down control command is used for controlling the window to be lowered down.
Specifically, the window lifting may be controlled to lift at a constant speed, or a corresponding lifting strategy may be executed according to the type of the window action trigger source, which is not limited herein. The window descending control may be to control the window to descend at a constant speed, or may be to execute a corresponding descending strategy according to the type of the window action triggering source, which is not limited herein.
In this embodiment of the present application, when the window action triggering event is triggered by the window action triggering source and the window control command is received by the window control when the window action triggering source sends the window control command, it may be determined that the window controller detects the window action triggering event.
S12: and executing a holding process on the window control command to continuously send the window control command to a bus until a next window action triggering event is detected.
The holding processing performed on the window control command may specifically be a window control command that records a current window action triggering event by software inside the window controller, and maintains the window control command unchanged until a new window action triggering event is detected.
S13: and continuously sending a trigger source signal to the bus according to the car window action trigger source until the next car window action trigger event is detected.
To enable the data management background to record to whom the window control command was issued, the window controller may query the triggering source of the window action triggering event it detects.
In the embodiment of the present application, the window action triggering source includes, but is not limited to: pulse width modulation (Pulse width modulation, PWM) sources, vehicle-mounted telematics BOX (T-BOX), voice control signal trigger sources, remote keyless entry (Remote Keyless Entry, RKE), passive keyless entry (Passive Keyless Entry, PKE), bluetooth, optical rainfall sensors (Rain Light Sensor, RLS), cell phone applications, off-vehicle latch signal sources, vehicle speed sensing auto-close window signal sources, parking status auto-close window, car wash auto-close window, one-key lift window, rain and snow mode auto-close window, intelligent rest mode auto-close window, etc.
For example, when the window controller receives the window-up control command at time T1, the window controller may query a trigger source that issues the window-up control command, and assume that the window-up control command is issued by the trigger source that is the automatic window closing in the rainy and snowy mode, that is, the window action trigger source detected by the window controller is the automatic window closing in the rainy and snowy mode.
In the embodiment of the application, a unique identification code can be preset for each vehicle window action triggering source, and different vehicle window action triggering sources can be identified through the identification code. For example, the identification code of the PWM signal source is set to 01, the identification code of the T-BOX is set to 02, the identification code of the voice control signal trigger source is set to 03, the identification code of the remote keyless entry is set to 04, the identification code of the passive keyless entry is set to 05, the identification code of bluetooth is set to 06, the identification code of the optical rainfall sensor is set to 07, the identification code of the mobile phone application is set to 08, the identification code of the off-vehicle locking signal source is set to 09, the identification code of the vehicle speed sensing automatic window closing signal source is set to 09, the identification code of the parking state automatic window is set to 10, the identification code of the car washing automatic window closing is set to 11, the identification code of the one-key window is set to 12, the identification code of the automatic window closing in the snowy and rainy mode is set to 13, the identification code of the automatic window closing in the intelligent rest mode is set to 14, the identification code of the automatic window closing in the "space-time mode" is set to 15, and the like.
It should be noted that, the identification code of the vehicle window action triggering source may be set according to the actual situation, which is not particularly limited in this application.
Based on this, in an embodiment of the present application, the step S13 may include the following steps:
acquiring an identification code of the vehicle window action triggering source;
and generating a trigger source signal according to the identification code.
In a specific application, the trigger source signal may be expressed as: dwc_upkeeper=identification code of window motion trigger source. For example, the trigger source is a PWM signal source, the identity of which is encoded as 01, then the trigger source signal may be expressed as: dwc_upkeeppsrc=01.
After the window controller determines the window action triggering source, the current window action triggering source can be recorded, and the triggering source signal is continuously sent to the bus, so that the triggering source corresponding to the current window control instruction can be recorded on the bus, after the data management background is sent by the T-BOX acquisition bus data, the window action triggering source corresponding to the current window action triggering event can be recorded by the data management background, and therefore when a user fault report or complaint is received, a fault source can be queried, and the fault investigation efficiency is improved.
In order to facilitate the explanation of the beneficial effects of the window control method provided in the embodiments of the present application, fig. 3 shows a timing diagram of the window control method provided in the embodiments of the present application. As shown in fig. 3, at time T1, the window is actually operated as a window-up operation, the window-up operation is maintained for a period of time T1 to T2, and the non-operation state is restored at time T2. The window controller detects a window action triggering event (namely, the event that the source 1 triggers the window lifting action of the window) at the time T1, at this time, the window controller records the window control command (namely, the window lifting control command), and executes a holding process on the window control command, namely, the window lifting control command is still held after the window action is finished (after the time T2), and the window control command is updated to be the window lifting control command until the window lifting action is detected at the time T3.
Meanwhile, after the vehicle window controller inquires that the triggering source of the vehicle window action triggering event is the source 1, the vehicle window action triggering source can be recorded as the source 1, and information of the vehicle window action triggering source as the source 1 is continuously output to the bus until a new vehicle window action triggering event is detected. Here, since the trigger source of the window lowering operation at the time T3 is still the source 1, the trigger source information outputted after the time T3 is still the information that the trigger source is the source 1, and the trigger source information is changed to the information that the trigger source is the source 2 until the trigger source is changed to the source 2 at the time T5.
In an embodiment of the present application, the bus includes a CAN bus.
As can be seen from the foregoing, in the window control method provided in the embodiment of the present application, by performing a holding process on a window control instruction of the window trigger event in a window controller, and continuously sending the window control instruction to a bus until a new window action trigger event is received, so that when a vehicle-mounted telematics processor uploads the bus instruction to a data management background, the window control instruction can be acquired, and the data management background can record relevant information of the window control instruction.
Referring to fig. 4, fig. 4 is a schematic implementation flow chart of another vehicle window control method according to an embodiment of the present application. As shown in fig. 4, in the embodiment of the present application, the information about the window action triggering event includes a window action type, and in the embodiment of the present application, the window action type includes a window lifting action type and a window lowering action type. When the window action triggering event is detected, the window controller can determine the window action type corresponding to the window action triggering event.
For example, when the window controller receives a window lowering control command from the passenger to open the window at time T3, the window controller determines that the window action type is a window lowering action type.
The above window control method may include the steps of:
s14: and judging whether the window action type is the same as the window action type of the previous window control instruction, if so, executing S15, otherwise, executing S16.
S15: and keeping the window control command unchanged, and continuously executing the keeping process on the window control command so as to continuously send the window control command to a bus.
S16: and updating the window control command, and executing a holding process on the updated window control command to continuously send the updated window control command to a bus until a next window action triggering event is detected.
In the embodiment of the application, when the window action triggering event is detected, whether the window action type of the current window triggering event is the same as the window action type of the last window triggering event or not is compared, and under the condition that the window action type of the current window triggering event is the same as the window action type of the last window triggering event, the original window action instruction is kept continuously, and only under the condition that the window action instruction is different from the window action instruction, the window action instruction recorded by the window controller is changed, so that the change times of the window action instruction output by the window controller can be reduced.
For example, referring to fig. 3 again, if the window controller detects a window action triggering event at a time T1, a time T3, and a time T5, respectively, and the window controller detects a window lowering action triggered by the source 1 at a time T3, for example, the window action type (i.e., window lowering action type) of the window action triggering event detected at a time T3 is compared with the window action type detected at a time T1, and since the window action type detected at a time T1 is a window raising action type, the window action type and the window action type are different, the window controller updates the window raising control command to a window lowering control command, and performs a hold process on the window lowering control command, so that the window controller continuously outputs the window lowering control command to the bus. Taking the time T5 as an example, if the window controller detects the window lowering action triggered by the source 2 at the time T5, the window action type (i.e. window lowering action type) of the window action triggering event detected at the time T5 is compared with the window action type detected at the time T3, and since the window action type detected at the time T3 is also the window lowering action type, the window action type and the window lowering action type are the same, the window controller keeps the window lowering action command unchanged, and continuously sends the window lowering action command to the bus.
Referring to fig. 5, fig. 5 shows a schematic implementation flow chart of another vehicle window control method according to an embodiment of the present application. In an embodiment of the present application, the method for controlling a vehicle window may include the following steps:
s17: and judging whether the window action triggering source of the window action triggering event is the same as the window action triggering source corresponding to the last triggering source signal, if so, executing S18, otherwise, executing S19.
S18: and keeping the trigger source signal unchanged, and continuously sending the trigger source signal to the bus.
S19: updating the trigger source signal and continuously sending the updated trigger source signal to the bus.
In the embodiment of the application, when the window action triggering event is detected, whether the window action triggering source of the current window triggering event is the same as the window action triggering source of the last window triggering event or not is compared, and under the condition that the window action triggering source and the window action triggering source are the same, the original triggering source signals are kept continuously, and only under the condition that the window action triggering source signals are different, the triggering source signals are changed, so that the changing times of the triggering source signals output by the window controller can be reduced.
For example, referring to fig. 3 again, when the window controller detects the window action triggering event at the time T1, the time T3, and the time T5, taking the example that the window controller detects the window lowering action triggered by the source 1 at the time T3, the window action triggering source (source 1) of the window action triggering event detected at the time T3 is compared with the window action triggering source detected at the time T1, and since the window action triggering source detected at the time T1 is also the source 1, both are the same, the window controller keeps the triggering source signal dwc_uppkeesrc=01 unchanged. Taking the time T5 as an example, when the window controller detects the window lowering action triggered by the source 2 at the time T5, the window action trigger source (source 2) of the window action trigger event detected at the time T5 is compared with the window action trigger source detected at the time T3, and since the window action trigger source detected at the time T3 is the source 1, the window controller updates the trigger source signal from dwc_uppkeesrc=01 to dwc_uppkeesrc=02, and continuously sends the trigger source signal of dwc_uppkeesrc=02 to the bus.
Referring to fig. 6, fig. 6 is a schematic implementation flow chart of another window control method according to an embodiment of the present application. In this embodiment of the present application, the window controller sends a signal flag bit to the bus, and accordingly, the window control method may further include the following steps:
s20: and determining parameters of signal zone bits according to the window action type of the window action triggering event and a window action triggering source.
In the embodiment of the present application, since the embodiment of the present application performs the hold processing on the window control command and the window action triggering source, if the same window action is triggered by the same window action triggering source within a period of time, the two window action triggering events cannot be distinguished on the bus, and in order to enable the window action triggering event to be distinguished, the embodiment of the present application sets a signal flag bit to record the window action triggering event.
Specifically, the step S20 may include the steps of:
and if the window action type of the window action triggering event is the same as the window action type of the previous window control instruction, and the window action triggering source of the window action triggering event is the same as the window action triggering source in the previous triggering source signal, setting the signal flag bit as a first state bit.
In the embodiment of the application, since the action trigger source of the current window action trigger event is consistent with the action trigger source of the last window action trigger event, the window action type of the current window action trigger event is also the same as the window action type of the last window action trigger event, then the window controller cannot update the window control instruction and the trigger source signal which are being sent, then the bus data acquired by the T-BOX cannot distinguish the two window action trigger events, and the two window action trigger events are identified as one window action trigger event, so that the occurrence time of the fault is not beneficial to determination. Therefore, when the action trigger source of the current window action trigger event is the same as the action trigger source of the previous window action trigger event, and the window action type of the current window action trigger event is also the same as the window action type of the previous window action trigger event, the window controller may set the signal flag bit to a first state bit, where the first state bit is used to indicate that a new window action trigger event is detected.
In a specific application, the signal flag bit may include 2 bits, and the first state bit of the signal flag bit may be 01. The initial status bit of the signal flag bit may be 00. Under other conditions, the signal zone bit is 00, and only when the action trigger source of the current window action trigger event is the same as the action trigger source of the last window action trigger event, and the window action type of the current window action trigger event is also the same as the window action type of the last window action trigger event, the window controller sets the signal zone bit to be 01, so that bus data acquired by the T-BOX can distinguish the two window action trigger events based on the parameters of the signal zone bit.
It should be noted that the initial state bit and the first state bit of the signal flag bit may be set according to actual situations, for example, the initial state bit may be set to 10, the first state bit may be set to 00, or the initial state bit may be set to 01, the first state bit may be set to 11, and so on.
In another embodiment of the present application, the step S20 may further include the steps of:
and when the time length of the signal marker bit set as the first state bit reaches a preset time threshold value, setting the signal marker bit as an initial state bit.
In the embodiment of the present application, the preset time threshold may be set according to actual situations, for example, set to 20 s.
The signal flag bit is set to be the first state bit and kept for the duration corresponding to the preset time threshold value, so that the T-BOX can acquire the jump condition, further, background data can record relevant information of each window action triggering event, and when the duration of the signal flag bit set to be the first state reaches the preset time threshold value, the signal flag bit is set to be the initial state bit, and the initial state is recovered, so that false identification is avoided.
It should be understood that the sequence number of each step in the foregoing embodiment does not mean that the execution sequence of each process should be determined by the function and the internal logic of each process, and should not limit the implementation process of the embodiment of the present application in any way.
