[0088] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0089] The disclosure below provides many different embodiments or examples to realize the different structures of the present application. In order to simplify the disclosure of the present application, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present application. In addition, the present application can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0090] In order to solve the technical problem in the prior art that, in the scenario where the physical buttons of the vehicle computer are cancelled, the user needs to touch the vehicle computer screen to implement any vehicle computer control operation, which causes the user to be distracted from clicking the vehicle computer screen, thereby increasing the risk of vehicle driving, the present application provides a vehicle computer control method, device and vehicle computer, which can improve the convenience of user experience and effectively avoid the situation where the user is distracted from the vehicle computer control during driving, thereby increasing the risk of vehicle driving.

[0091] Figure 1 A flow chart of an embodiment of a vehicle control method provided in an embodiment of the present application.

[0092] In one embodiment, the method is applied to a vehicle computer. Figure 1 As shown, the following steps are included:

[0093] Step 101: Monitor the air pressure value inside the vehicle computer through a sensing device arranged inside the vehicle computer.

[0094] The above-mentioned sensing device is, for example, an air pressure sensor, which is arranged inside the vehicle computer and is used to monitor the air pressure value inside the vehicle computer.

[0095] As an optional implementation method, use SensorManager (sensor management component) to register the air pressure sensor to the event handler sensorEventListener, so that the air pressure sensor can monitor the air pressure value inside the vehicle.

[0096] In one embodiment, the air pressure sensor is controlled to monitor the air pressure value inside the vehicle in real time. In practical applications, real-time monitoring can be achieved by continuously and periodically collecting data at a very short time interval.

[0097] As an optional implementation method, in sensorEventListener, use the onCreate() method to monitor and record the standard air pressure value inside the car when the pressure sensor is initialized, use sensorEvent.values[0] to record the monitored air pressure value inside the car, and use the onSensorChanged method to respond to changes in the air pressure value inside the car.

[0098] Step 102: Determine whether a pressing operation occurs in a designated area on the vehicle computer according to the change in the air pressure value, wherein the designated area is located on the housing of the vehicle computer.

[0099] First of all, it should be explained that in the prior art, the screen of the car computer is usually a touch screen. The essence of the touch screen is a sensor, which consists of a touch detection component and a touch screen controller. The touch detection component is installed in front of the screen to detect the user's touch position, and send it to the touch screen controller after receiving the touch operation; the main function of the touch screen controller is to receive touch information from the touch point detection device, and convert it into touch point coordinates and send it to the CPU, and at the same time it can receive commands sent by the CPU and execute them. It can be seen that when the screen area of ​​the car computer is pressed, although it will also cause the air pressure inside the car computer to change, the control principle of controlling the car computer by pressing the screen of the car computer is obviously different from the control principle of controlling the car computer by detecting the change of the air pressure inside the car computer, and it is also irrelevant. Therefore, the technical solution provided in the embodiment of the present application is intended to detect the user's pressing operation on the pressable area outside the screen area on the car computer. Based on this, the above-mentioned designated area is located on the outer shell of the car computer.

[0100] Furthermore, when a pressing operation occurs in the designated area of ​​the vehicle computer, the air pressure inside the vehicle computer will change due to the change in the space inside the vehicle computer, and the air pressure value inside the vehicle computer will show a certain change trend. Therefore, in step 102, it is determined whether a pressing operation occurs in the designated area of ​​the vehicle computer according to the change in the air pressure value inside the vehicle computer. As for how to determine whether a pressing operation occurs in the designated area of ​​the vehicle computer according to the monitored change in the air pressure value inside the vehicle computer, it will be described in detail below. Figure 2The process shown is explained in detail and will not be described in detail here.

[0101] Step 103: When it is determined that a pressing operation occurs in the designated area on the vehicle computer, the vehicle computer is controlled to execute a corresponding vehicle computer control instruction.

[0102] In one embodiment, the corresponding vehicle control instruction refers to a vehicle control instruction associated with a designated area. Usually, one designated area is associated with one vehicle control instruction, so that a specific vehicle control operation can be achieved by pressing the designated area.

[0103] Furthermore, it can be seen from the above description that in some embodiments, a plurality of pressable areas, that is, a plurality of designated areas, may be provided on the vehicle computer, and each designated area has an associated vehicle computer control instruction, which can be implemented in the software through a configuration file or hard coding.

[0104] The technical solution provided by the embodiment of the present application monitors the air pressure value inside the vehicle computer by means of a sensing device arranged inside the vehicle computer, determines whether a pressing operation occurs in a designated area on the vehicle computer housing according to the change of the air pressure value inside the vehicle computer, and controls the vehicle computer to execute the corresponding vehicle computer control instruction when it is determined that a pressing operation occurs in the designated area on the vehicle computer, thereby realizing a non-contact vehicle computer control method, enabling the user to control the vehicle computer to execute the corresponding vehicle computer control instruction by pressing the designated area on the vehicle computer without directly touching the screen. This not only improves the convenience of the user experience, but more importantly, since the pressing operation on the designated area can be performed under relatively loose conditions, the user does not need to divert too much attention to the vehicle computer control during driving, thereby effectively avoiding the situation where the user is distracted during driving and increases the danger of driving the vehicle.

[0105] Figure 2 A flowchart of an embodiment of the present application for determining whether a pressing operation occurs in a specified area on a vehicle computer according to a change in the air pressure value inside the vehicle computer. Figure 2 The process shown in Figure 1 The basis of the process shown, including the following steps:

[0106] Step 201: Obtain the current air pressure value inside the vehicle computer.

[0107] Step 202: Determine whether the air pressure inside the vehicle computer has changed according to the current air pressure value inside the vehicle computer.

[0108] For ease of understanding, step 201 and step 202 are described in a unified manner as follows:

[0109] Whether the current air pressure value inside the vehicle computer has changed refers to whether the current air pressure value inside the vehicle computer has changed compared to the set standard air pressure value inside the vehicle computer, wherein the standard air pressure value inside the vehicle computer refers to the air pressure value of the vehicle computer without any pressing operation. Based on this, the specific implementation of determining whether the air pressure inside the vehicle computer has changed according to the current air pressure value inside the vehicle computer includes: comparing the current air pressure value inside the vehicle computer with the set standard air pressure value inside the vehicle computer, and when the current air pressure value inside the vehicle computer is different from the standard air pressure value inside the vehicle computer, determining that the air pressure inside the vehicle computer has changed; when the current air pressure value inside the vehicle computer is the same as the standard air pressure value inside the vehicle computer, determining that the air pressure inside the vehicle computer has not changed.

[0110] Here, those skilled in the art can understand that each time the air pressure value inside the vehicle computer is monitored, it means that the current air pressure value inside the vehicle computer is monitored, so the current air pressure value inside the vehicle computer is obtained, and whether the air pressure inside the vehicle computer has changed is determined according to the current air pressure value inside the vehicle computer. In this way, it is possible to monitor whether the air pressure inside the vehicle computer has changed in real time.

[0111] Step 203: when it is determined that the air pressure inside the vehicle computer has changed, a sequence of air pressure values ​​inside the vehicle computer monitored is obtained, where the air pressure value sequence includes N air pressure values ​​monitored within a set time interval, where N is a natural number greater than 1.

[0112] Step 204: Determine whether a pressing operation occurs in a designated area on the vehicle computer according to the air pressure value sequence.

[0113] For ease of understanding, step 203 and step 204 are described in a unified manner as follows:

[0114] It can be seen from the description of the above steps 201 and 202 that each time the current air pressure value inside the vehicle computer is monitored by the air pressure sensor, the current air pressure value inside the vehicle computer is compared with the standard air pressure value inside the vehicle computer to determine whether the air pressure value inside the vehicle computer has changed. When the air pressure value inside the vehicle computer has changed, it means that the vehicle computer has been pressed. In other words, when it is determined that the air pressure inside the vehicle computer has changed, it can be determined that the vehicle computer has been pressed.

[0115] Further, through Figure 1It can be learned from the relevant description in the process shown that: when a pressing operation occurs in a designated area on the vehicle computer, the air pressure value inside the vehicle computer will show a certain trend of change. Therefore, when it is determined that the air pressure inside the vehicle computer has changed, that is, when it is determined that a pressing operation has occurred on the vehicle computer, the sequence of air pressure values ​​monitored within the set time interval is obtained, so as to determine the changing trend of the air pressure inside the vehicle computer within the set time interval according to the air pressure value sequence, and then judge whether a pressing operation has occurred in the designated area on the vehicle computer by the changing trend. Among them, the set time interval uses the current time as the end time and the set duration (for example, 1 second) as the interval duration. The sequence of air pressure values ​​monitored within the set time interval includes N air pressure values, where N is a natural number greater than 1, for example, N is 4. Among them, N can be the total number S of air pressure values ​​monitored within the set time interval, or it can be less than S, and the embodiments of the present application do not limit this.

[0116] The specific implementation of judging whether a pressing operation occurs in a designated area on the vehicle computer according to a changing trend of the air pressure inside the vehicle computer within a set time interval includes: determining that a pressing operation occurs in the designated area on the vehicle computer when it is determined that the changing trend matches a target air pressure changing trend associated with the designated area on the vehicle computer; and determining that no pressing operation occurs in the designated area on the vehicle computer when it is determined that the changing trend does not match a target air pressure changing trend associated with the designated area on the vehicle computer.

[0117] In addition, in one embodiment, a plurality of pressable areas, that is, a plurality of designated areas, may be provided on the vehicle computer, and each designated area has a change trend associated therewith, which is the change trend of the air pressure inside the vehicle computer when a pressing operation occurs on the designated area. Generally, the change trends associated with different designated areas are different. For example, when the designated area is located on the vehicle computer frame, when the designated area is pressed, the air pressure inside the vehicle computer will show a slightly downward change trend; when the designated area is located on the front wall or the rear wall of the vehicle computer, when the designated area is pressed, the air pressure inside the vehicle computer will show a steep upward change trend. Based on this, it is also possible to determine on which designated area the pressing operation occurs according to the change trend of the air pressure inside the vehicle computer, and then control the vehicle computer to execute the vehicle computer control instruction associated with the designated area where the pressing operation occurs. Through this embodiment, the diversity of vehicle computer control achieved by pressing the vehicle computer can be further enriched to better meet user needs.

[0118] Figure 2The process shown in the figure obtains the current air pressure value monitored inside the vehicle computer, and determines whether the air pressure inside the vehicle computer has changed based on the current air pressure value inside the vehicle computer, so as to monitor in real time whether a pressing operation has occurred on the vehicle computer; thereafter, when it is determined that the air pressure inside the vehicle computer has changed, by obtaining the sequence of air pressure values ​​monitored inside the vehicle computer, it is possible to determine whether a pressing operation has occurred in a designated area on the vehicle computer based on the air pressure value sequence.

[0119] pass Figure 1 and Figure 2 It can be seen from the embodiment shown that the technical solution provided by the embodiment of the present application has two core processes, namely, monitoring and storing the air pressure value inside the vehicle computer, and determining whether a pressing operation occurs on a designated area on the vehicle computer according to the change of the air pressure value inside the vehicle computer. The following is an explanation of the two core processes in combination with practical applications:

[0120] First, if Figure 3 As shown, in the process of monitoring and storing the air pressure value inside the vehicle computer, first use SensorManage to register the air pressure sensor pressureSensor to the event processor sensorEventListener, so that the air pressure sensor can monitor the air pressure value inside the vehicle computer.

[0121] In sensorEventListener, use the onCreate() method to monitor and record the standard air pressure value normalPressure inside the vehicle when the air pressure sensor is initialized. Use the onSensorChanged method to respond to changes in the air pressure value inside the vehicle, and use sensorEvent.values[0] to record the monitored air pressure value inside the vehicle.

[0122] Get sensorEvent.values[0] and store it in the global variable pressuer. That is, every time the air pressure value inside the vehicle is monitored by the sensor device, the value of the preset global variable is updated to the currently monitored air pressure value. Through this processing, the global variable can always record the current air pressure value monitored inside the vehicle.

[0123] Use the scheduleAtFixedRate() method in ScheduledExecutorService to create a scheduled task. For example, push the global variable pressure into the queue ArrayBlockingQueue every 250 milliseconds. <float>Optionally, the size of the queue is 4, so that the air pressure change within one second can be recorded through the queue. If the queue is not full, the air pressure value is added. If the queue is full, the first element of the queue is discarded and the current air pressure value is added. In other words, the value of the global variable is obtained at every set time interval (for example, 250ms), and the obtained value of the global variable is written into the set queue. When the set queue is full, the first value in the set queue is discarded, and then the obtained value of the global variable is written into the set queue.

[0124] Secondly, if Figure 4 As shown, the designated area is located on the border of the vehicle computer, and when it is determined that a pressing operation occurs in the designated area on the vehicle computer, the vehicle computer is controlled to execute a corresponding vehicle computer control instruction, including: when it is determined that a pressing operation occurs in the designated area on the vehicle computer, the vehicle computer is controlled to execute a corresponding vehicle computer control instruction to control the vehicle computer to be silent. In this application scenario, a flow chart is provided to determine whether a pressing operation occurs in the designated area on the vehicle computer according to a change in the air pressure value inside the vehicle computer.

[0125] Figure 4 In the process shown, the value of the global variable is obtained, and the value of the global variable is determined as the current air pressure value inside the vehicle computer. Then, it is determined whether the air pressure inside the vehicle computer has changed according to the current air pressure value monitored inside the vehicle computer. When it is determined that the air pressure inside the vehicle computer has changed, the monitored air pressure value sequence inside the vehicle computer is obtained, specifically including obtaining the values ​​in the above-mentioned set queue, and the values ​​obtained from the set queue form the air pressure value sequence inside the vehicle computer. Then, the change trend of the air pressure inside the vehicle computer within the set time interval is determined according to the air pressure value sequence, and then it is determined whether a pressing operation occurs on the designated area of ​​the vehicle computer according to the change trend. Among them, in the application scenario where the above-mentioned designated area is located at the border of the vehicle computer, the specific implementation of determining the changing trend of the air pressure inside the vehicle computer within a set time interval according to the air pressure value sequence includes: comparing the Nth air pressure value in the air pressure value sequence with the standard air pressure value inside the vehicle computer to obtain a first comparison result; determining the first difference between each of the N air pressure values ​​in the air pressure value sequence and the standard air pressure value inside the vehicle computer, and comparing the absolute value of each first difference with the set first difference threshold to obtain a second comparison result; determining the average value of the N air pressure values ​​in the air pressure value sequence, determining the second difference between the average value and the standard air pressure value inside the vehicle computer, and comparing the absolute value of the second difference with the set second difference threshold to obtain a third comparison result; determining the changing trend of the air pressure inside the vehicle computer within the set time interval based on the first comparison result, the second comparison result, and the third comparison result.

[0126] Specifically, Figure 4 As shown, the Nth air pressure value in the air pressure value sequence is the current air pressure value inside the vehicle computer, and the first comparison result is used to indicate whether the current air pressure value inside the vehicle computer is smaller than the standard air pressure value inside the vehicle computer by more than 0.15. If the current air pressure value is smaller than the standard air pressure value inside the vehicle computer by more than 0.15, it can be preliminarily determined that a pressing operation on the vehicle computer frame is currently occurring.

[0127] Furthermore, the second comparison result is used to indicate whether the absolute value of the first difference between the air pressure value and the standard air pressure value inside the vehicle is greater than or equal to a first difference threshold, such as 0.1. If the absolute value of the first difference between each air pressure value in the air pressure value sequence and the standard air pressure value inside the vehicle is greater than or equal to 0.1, the set time interval can be determined, such as the air pressure values ​​in the previous second are all within the standard air pressure range.

[0128] The third comparison result is used to indicate whether the absolute value of the second difference between the average value of the N air pressure values ​​in the air pressure value sequence and the standard air pressure value inside the vehicle computer is less than or equal to a set second difference threshold, such as 0.1. When the absolute value of the second difference between the average value of the N air pressure values ​​in the air pressure value sequence and the standard air pressure value inside the vehicle computer is less than or equal to the set second difference threshold, it can be determined that the N air pressure values ​​in the air pressure value sequence are substantially the same, that is, it can be determined that the air pressure inside the vehicle computer is relatively stable within the set time interval.

[0129] From the above description, it can be seen that if the changing trend of the air pressure inside the car computer is: the air pressure value in the previous second is relatively stable and basically within the standard air pressure range, and there is a slight decrease at the current moment, it can be determined that a pressing operation has occurred on the border of the car computer.

[0130] Finally, when it is determined that a pressing operation occurs on the border of the car computer, the Vibrator object is obtained through getSystemService, and then the Vibrator.vibrate method is called to enable muting, thereby realizing one-click muting of the car computer.

[0131] Finally, it is to be noted that, in actual applications, the above-mentioned vehicle control instructions can also be navigation control instructions, air conditioning adjustment control instructions, audio playback control instructions, etc. This depends on the user's function setting of the pressable area on the vehicle, and the embodiments of the present application do not limit this.

[0132] Figure 4 The process shown in the figure realizes a non-contact one-button mute control method for the car computer, which enables the user to control the mute of the car computer by pressing the border of the car computer without directly touching the screen. This not only improves the convenience of the user experience, but more importantly, because the pressing operation on the designated area can be performed under relatively loose conditions, the user does not need to divert too much attention to the car computer control during driving, which can effectively avoid the situation where the user is distracted during driving and increase the danger of driving the vehicle.
