Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
In one embodiment, as shown in fig. 1, there is provided a method for adjusting brightness of a car navigation screen, including the following steps:
The vehicle-mounted navigation equipment is provided with a display screen, and the display screen can be used for displaying navigation information. The screen brightness represents the luminous intensity of the screen of the vehicle-mounted navigation equipment, and the current screen brightness refers to the luminous intensity of the screen when the vehicle-mounted navigation equipment acquires data. The vehicle-mounted navigation equipment can acquire the current screen brightness in the using process. The vehicle-mounted navigation device can acquire the current screen brightness in real time, and can also acquire the current screen brightness according to a certain frequency, such as once every 3 seconds.
The in-vehicle navigation apparatus may acquire brightness information of an environment outside the vehicle as the first brightness information. Specifically, the vehicle-mounted navigation device can detect the brightness information of the external environment of the vehicle through the first brightness sensor, and the brightness sensor can sense the brightness of light and convert the brightness of light into a usable output signal. The first brightness sensor may be arranged outside the vehicle, in particular in the front windscreen region of the vehicle. Furthermore, the first brightness sensor can be arranged in a front windshield area corresponding to the position of the user and faces the front of the vehicle so as to detect the ambient brightness information in front of the vehicle. The brightness information acquired by the first brightness sensor arranged in the area is helpful for truly reflecting the brightness of the environment outside the vehicle observed by eyes of a user in the driving process. The first brightness sensor can be connected with the vehicle-mounted navigation equipment in a wired mode, so that the first brightness sensor can transmit detected first brightness information to the vehicle-mounted navigation equipment; the first brightness sensor can also be connected with the vehicle-mounted navigation equipment in a wireless mode, so that the first brightness sensor can send the detected first brightness information to the vehicle-mounted navigation equipment.
And 106, detecting the brightness of the internal environment of the vehicle to obtain second brightness information.
The vehicle-mounted navigation device can detect the brightness information of the internal environment of the vehicle to obtain second brightness information. Specifically, the vehicle-mounted navigation device may detect brightness information of the interior of the vehicle using the second brightness sensor to obtain the second brightness information. The second brightness sensor is arranged in the vehicle and is specifically used for detecting the brightness information of the driving position, and the brightness information of the driving position is used as the second brightness information. The second brightness sensor can be connected with the vehicle-mounted navigation equipment in a wired mode so that the second brightness sensor can transmit detected second brightness information to the vehicle-mounted navigation equipment; the second brightness sensor can also be connected with the vehicle-mounted navigation equipment in a wireless mode, so that the second brightness sensor can send the detected second brightness information to the vehicle-mounted navigation equipment. The first brightness sensor and the second brightness sensor simultaneously acquire the ambient brightness information, so that the ambient brightness information can be acquired in real time, and the ambient brightness information can also be acquired according to the preset frequency.
And step 108, comparing the first brightness information with the second brightness information to obtain a brightness difference value.
And step 110, adjusting the current screen brightness according to the brightness difference value.
And the vehicle-mounted navigation equipment compares the obtained first brightness information with the second brightness information, and calculates to obtain a brightness difference value between the first brightness and the second brightness. Specifically, the vehicle-mounted navigation device performs difference operation on first brightness in the first brightness information and second brightness in the second brightness information to obtain a brightness difference value. When the first brightness is larger than the second brightness, the external environment of the vehicle is brighter than the internal environment of the vehicle, and the brightness difference is a positive number; when the first brightness is less than the second brightness, it means that the environment outside the vehicle is darker than the environment inside the vehicle, and the brightness difference is a negative number. The absolute value of the luminance difference value indicates a difference between the luminance of the environment inside the vehicle and the luminance of the environment outside the vehicle. The vehicle-mounted navigation equipment can adjust the current screen brightness according to the brightness difference value.
The method for adjusting the brightness of the vehicle-mounted navigation screen obtains the current screen brightness, detects and obtains first brightness information of an external environment of the vehicle and second brightness information of an internal environment of the vehicle, obtains a brightness difference value between the first brightness information and the second brightness information by comparing the first brightness information with the second brightness information, and adjusts the current screen brightness according to the brightness difference value. The current screen brightness is automatically adjusted according to the brightness difference value between the first brightness information and the second brightness information, the environment brightness inside and outside the vehicle is fully considered, the vehicle-mounted navigation screen brightness is made to adapt to the environment brightness inside and outside the vehicle, and a user can conveniently observe the vehicle-mounted navigation information in the driving process.
In one embodiment, as shown in fig. 2, the step 110 of adjusting the current screen brightness according to the brightness difference value includes:
The vehicle-mounted navigation equipment can acquire the acquisition time of the brightness information and the weather information, and the brightness information comprises first brightness information and second brightness information. Because the first brightness sensor and the second brightness sensor respectively acquire the first brightness information and the second brightness information at the same time, the first brightness information and the second brightness information have the same acquisition time and weather information correspondingly. The collecting time of the brightness information is the time when the brightness sensor detects the ambient brightness during the running process of the vehicle, and the collecting time may be any one time of 24 hours, for example, 13 hours, 27 minutes and 42 seconds. The vehicle-mounted navigation equipment can divide a day into different time periods according to the situation of the location of the vehicle, and the acquisition time can correspond to the time periods. For example, the vehicle-mounted navigation device may divide a day into day and night according to sunrise and sunset times of a location of the vehicle, and when the collection time is within 6 hours, 30 minutes and 18 hours, 30 minutes, the collection time corresponds to a day period; otherwise, the acquisition time corresponds to the night time period. The vehicle-mounted navigation equipment can also divide a day into time periods such as morning, noon, afternoon, evening, midnight and the like, and the sunshine light intensity is different in different time periods. The vehicle-mounted navigation equipment can also acquire weather information of the location of the vehicle when the vehicle runs, wherein the weather information comprises sunny weather, cloudy weather, rain, fog, snow, floating dust, raised sand and the like. The sunshine intensity corresponding to different weather information is also different.
And step 204, acquiring a corresponding adjusting mode according to the acquisition time and the weather information.
The vehicle-mounted navigation equipment acquires an adjusting mode by combining the acquisition time of the brightness information and the weather information, and the adjusting mode is preset to correspond to the acquisition time and the weather information. Different adjusting modes correspond to different screen basic brightness and adjusting modes. When the vehicle-mounted navigation equipment starts to work, the basic brightness of the screen can be adjusted according to the acquired adjusting mode, and the vehicle-mounted navigation equipment can adjust the current screen brightness of the vehicle-mounted navigation equipment according to the adjusting mode of the adjusting mode in the vehicle driving process. For example, when the vehicle is driving in the daytime and the weather where the vehicle is located is clear, the sunshine is brighter in the clear daytime, and the brightness of the external environment is relatively higher, so the brightness of the screen base of the corresponding adjusting mode is relatively higher. When the vehicle runs in the daytime and the weather where the vehicle is located is rain, the sunshine in the rainy day is relatively dark in the sunny day, and therefore the screen basic brightness of the corresponding adjusting mode is relatively low. When the vehicle is driven late at night, the brightness of the external environment is relatively low late at night compared to the daytime, and thus the basic brightness of the screen of the corresponding adjustment mode is relatively low.
And step 206, acquiring a corresponding adjusting gradient according to the brightness difference.
And step 208, adjusting the current screen brightness according to the adjusting mode and the adjusting gradient.
And the vehicle-mounted navigation equipment acquires a corresponding adjusting gradient according to a brightness difference value obtained by comparing the first brightness information with the second brightness information. The screen brightness of the vehicle-mounted navigation equipment is preset with a fixed total number of steps, namely the screen brightness is divided into a fixed number of steps from the lowest to the highest. For example, the total number of steps of the screen brightness is 7 steps, 0 step represents the lowest brightness, 7 steps represents the highest brightness, and the brightness of the screen can be adjusted between 0 and 7, and each adjustment can be adjusted to be higher or lower by at least one step. The brightness difference value and the adjusting gradient have a corresponding relation, and the brightness difference value within a certain amount corresponds to the first-order adjusting gradient. And the vehicle-mounted navigation equipment adjusts the current screen brightness according to the acquired corresponding adjustment mode and the corresponding adjustment gradient.
In this embodiment, the vehicle-mounted navigation device also acquires the acquisition time and the weather information of the brightness information while adjusting the current screen brightness through the first brightness information and the second brightness information, and comprehensively considers the influence of the vehicle running time and the weather of the location on the sunshine intensity. The basic brightness and the adjusting gradient of the vehicle-mounted navigation screen are flexibly adjusted, so that a user can observe the vehicle-mounted navigation information conveniently in the driving process.
In one embodiment, the step 110 of adjusting the current screen brightness according to the brightness difference value includes: acquiring position information of vehicle running; identifying whether a place corresponding to the position information changes; if the place is changed, acquiring a corresponding adjusting mode according to the changed place; obtaining a corresponding adjusting gradient according to the brightness difference; and adjusting the current screen brightness according to the adjusting mode and the adjusting gradient.
The vehicle-mounted navigation equipment positions the position information of the vehicle according to the navigation function, and identifies the place where the vehicle is located according to the position information, wherein the place is divided into an outdoor place and an indoor place, and the indoor place comprises closed or semi-closed places such as a parking lot and a tunnel. The position information of the vehicle continuously changes in the driving process, and the vehicle-mounted navigation equipment identifies whether the corresponding place changes or not through the vehicle position information. For example, the vehicle may always travel on an outdoor road, and at this time, although the position information of the vehicle changes, the location corresponding to the position information does not change. When a vehicle enters a tunnel from an outdoor road, the position information of the vehicle changes at this time, and the corresponding location also changes. And when the place corresponding to the position information changes, the vehicle-mounted navigation equipment acquires a corresponding adjusting mode according to the changed place. And a corresponding adjusting mode is preset in each place. For example, the external environment brightness of the outdoor road is relatively high, and the screen basic brightness of the corresponding adjusting mode is also relatively high; the external ambient brightness of the tunnel is relatively low, and the screen base brightness of the corresponding adjusting mode is also relatively low. When the place where the vehicle is located changes, namely when the vehicle enters the tunnel from an outdoor road, the brightness of the external environment changes from high to low, and the vehicle-mounted navigation equipment acquires a corresponding adjusting mode according to the changed place, namely the tunnel, namely, the basic brightness of the screen is adjusted to be low. When the vehicle exits from the tunnel, the vehicle-mounted navigation equipment acquires the corresponding adjusting mode of the outdoor road, namely, the basic brightness of the screen is increased. And the vehicle-mounted navigation equipment acquires a corresponding adjusting gradient according to the brightness difference value, and adjusts the current screen brightness according to the adjusting mode and the adjusting gradient.
In this embodiment, the vehicle-mounted navigation device acquires the adjustment gradient through the first brightness information and the second brightness information to adjust the current screen brightness, and also acquires the position information of the vehicle running, identifies whether the corresponding place changes according to the position information, acquires the corresponding adjustment mode according to the changed place if the corresponding place changes, and adjusts the current screen brightness by integrating the adjustment mode and the adjustment gradient, so that a user can conveniently observe the vehicle-mounted navigation information in the driving process.
In an embodiment, after the first brightness information and the second brightness information are obtained and the brightness difference value is calculated, the vehicle-mounted navigation device may further obtain the collection time of the brightness information, the weather information and the position information of the vehicle driving at the same time, obtain a corresponding adjustment mode according to the collection time, the weather information and the change of the place, and adjust the current screen brightness according to the adjustment mode and the adjustment gradient. The vehicle-mounted navigation equipment can comprehensively acquire time, weather and places to acquire corresponding adjusting modes. For example, in a clear day, when a vehicle enters a tunnel from an outdoor road, the external environment brightness changes from high to low, and thus the corresponding adjustment mode is the down adjustment mode. At night, when the vehicle enters the tunnel from the outdoor road, the ambient brightness of the outdoor road may be lower than that of the tunnel, and the external ambient brightness is changed from low to high, so the corresponding adjustment mode is changed to high.
In this embodiment, the vehicle-mounted navigation device obtains a corresponding adjustment mode and an adjustment gradient by integrating the first brightness information, the second brightness information, the acquisition time of the brightness information, the weather information, the vehicle driving position information and other factors, and adjusts the current screen brightness. The brightness of the vehicle navigation screen is adjusted by combining the data information of multiple dimensions, so that the current screen brightness of the vehicle navigation adapts to the internal environment brightness and the external environment brightness of the vehicle, and a user can observe the vehicle navigation information conveniently in the driving process.
In one embodiment, the step 208 of adjusting the current screen brightness according to the adjustment mode and the adjustment gradient includes: acquiring a pre-stored mapping table; obtaining an adjusting gradient corresponding to the brightness difference in the mapping table; when the adjusting mode is the increasing mode, increasing the brightness of the current screen according to the adjusting gradient; and when the adjusting mode is the adjustment down mode, adjusting down the current screen brightness according to the adjusting gradient.
And a mapping table corresponding to each other exists between the brightness difference value and the adjusting gradient. The vehicle-mounted navigation equipment can obtain corresponding adjusting gradients from a pre-stored mapping table according to the brightness difference value between the first brightness information and the second brightness information, each adjusting gradient corresponds to a brightness difference value in a section of range, and the brightness difference value continuously corresponds to the adjusting gradients. The screen brightness of the vehicle navigation can only be adjusted within the range of adjusting the gradient, and only the brightness of the corresponding adjusting gradient can be adjusted each time, so that the current screen brightness is continuously adjusted. When the adjusting mode is increasing, the vehicle-mounted navigation equipment increases the current screen brightness to a corresponding gradient according to the adjusting gradient corresponding to the brightness difference; and when the adjusting mode is the lowering mode, the vehicle-mounted navigation equipment lowers the current screen brightness to the corresponding gradient according to the adjusting gradient corresponding to the brightness difference value.
In this embodiment, the vehicle-mounted navigation device obtains the adjustment gradient corresponding to the brightness difference value through the mapping table, and continuously adjusts the current screen brightness according to the adjustment mode and the adjustment gradient, so that the current screen brightness does not suddenly change due to the change of the ambient brightness, and the influence of the sudden change of the vehicle-mounted navigation screen brightness on the driving of the user is avoided.
In one embodiment, the method for adjusting brightness of the car navigation screen further includes: receiving a voice control instruction in the running process of a vehicle; recognizing a brightness adjusting keyword from the voice control instruction; and adjusting the current screen brightness according to the brightness adjusting keyword.
The vehicle-mounted navigation equipment can receive a voice control instruction of a user in the vehicle running process. The vehicle-mounted navigation equipment can receive the voice control instruction of the user in real time, and also can receive the voice control instruction of the user when receiving the voice input request. For example, the user may send the voice input request by triggering a preset control, which may be a button, or a region on the touch screen or a preset action performed on the touch screen. The user can speak after triggering the preset control, and the vehicle-mounted navigation equipment receives the voice control instruction of the user when receiving the voice input request. The voice control instruction is used for controlling the vehicle-mounted navigation equipment to adjust the current screen brightness, and the voice control instruction can be input through input equipment such as a microphone. The vehicle-mounted navigation device can identify brightness adjusting keywords from voice control instructions input by a user by utilizing a voice recognition technology, wherein the brightness adjusting keywords represent keywords with screen brightness adjusting information, and the keywords comprise 'high brightness', 'low brightness', 'bright', 'dark', 'screen', and the like. And when the vehicle-mounted navigation equipment identifies the brightness adjusting keyword from the voice control instruction, adjusting the current screen brightness according to the brightness adjusting keyword. For example, the user says "the screen is turned on a little", the vehicle-mounted navigation device identifies brightness adjusting keywords "screen" and "bright" in the screen, namely, the screen is turned on according to the brightness adjusting keywords. The user says that the screen brightness is a little lower, the vehicle-mounted navigation equipment identifies the brightness adjusting keywords screen and brightness is low, namely, the screen is dimmed according to the brightness adjusting keywords.
In the embodiment, the vehicle-mounted navigation equipment receives the voice control instruction during the running process of the vehicle, and adjusts the current screen brightness according to the brightness adjusting keyword in the voice control instruction. The brightness of the vehicle-mounted navigation screen does not need to be manually adjusted by a user in the driving process, so that the brightness of the vehicle-mounted navigation screen can be conveniently and individually adjusted by the user, and the user can conveniently observe the vehicle-mounted navigation information in the driving process.
