The technical solutions in the embodiments of the present invention will be described below with reference to the accompanying drawings in the embodiments of the present invention.
In embodiments of the invention, words such as "exemplary" or "such as" are used to mean serving as an example, instance, or illustration. Any embodiment or design described herein as "exemplary" or "e.g." in an embodiment should not be taken as preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "such as" is intended to present related concepts in a concrete fashion.
In the description of the present invention, "/" means "or" unless otherwise indicated, for example, A/B may mean A or B. "and/or" herein is merely an association relationship describing an association object, and means that three relationships may exist, for example, a and/or B may mean: a exists alone, A and B exist together, and B exists alone. Further, "at least one", "a plurality" means two or more. The terms "first," "second," and the like do not limit the number and order of execution, and the terms "first," "second," and the like do not necessarily differ.
In the existing design, because the heights of drivers are different and the comfortable sitting postures of the drivers are also different, when the drivers view information displayed on the electronic screen, the drivers can be blocked from view by the steering wheel, so that the drivers can not view important display contents, and the driving safety is affected.
In order to solve the above problems, the present invention provides a display device, a display method, a vehicle and a storage medium, wherein a position of eyes of a driver is obtained through a sensor, a visible area of a display screen is determined according to the position of eyes of the driver, a position of a shielding object and the position of the display screen, and the display screen is controlled to display a first display object in the visible area, wherein the display priority of the first display object is higher than a preset display priority. The display device provided by the invention can display the display objects with higher display priority than the preset display priority in the visible area after the positions of eyes of the driver are acquired, so that the drivers with different heights can drive in a comfortable posture and can also view the display objects with higher display priority than the preset display priority on the display screen.
As shown in fig. 1, an embodiment of the present invention provides a vehicle 10 including a power system 11 and a display device 12. Wherein the powertrain 11 is configured to drive the vehicle 10. The display device 12 may be a vehicle-mounted terminal including a display screen, or may be a multimedia terminal including a display screen.
As shown in fig. 2, the display device 12 includes: a controller 121, a sensor 122 and a display screen 123.
The controller 121 may be used to control the sensor 122 to obtain the position of the driver's eyes.
The controller 121 may also be configured to determine the viewable area of the display screen 123 based on the acquired position of the driver's eyes, as well as the position of the obstruction and the position of the display screen stored in a memory (not shown) of the display device.
The controller 121 may also be used to control the display content of the display screen 123. Illustratively, the controller 121 controls the display screen 123 to display a first display object in the visible region, the first display object having a higher display priority than a preset display priority.
The sensor 122 may be used to obtain the position of the driver's eyes under control of the control 121.
Alternatively, the sensor 122 may be composed of a human eye recognition device 122a, a distance detection device 122b, and a seat weight detection device 122 c.
By way of example, fig. 3 shows a detection schematic diagram of a sensor 122, in which in the case where the weight of a person on the driver's seat is detected by a seat weight detecting means 122c, a person eye recognizing means 122a recognizes the eyes of the driver, and the position of the eyes of the driver is detected by a distance detecting means 122 b.
Alternatively, the sensor 122 may also be an infrared matrix disposed on top of the vehicle.
For example, fig. 4 shows a schematic diagram of detection by the sensor 122, and the information of the head and eyes of the driver in the vehicle is obtained through the infrared matrix 122d multiple infrared ranging.
The display screen 123 is used to display vehicle travel information and vehicle information. The vehicle driving information comprises vehicle speed per hour, engine speed and the like, and the vehicle information comprises vehicle residual oil quantity, mileage, electric quantity and the like.
Fig. 5 illustrates a display screen 123 and display contents of the display screen 123, and fig. 5 illustrates display contents including information of a speed of time, a following situation, turn signal information, driving assistance information, mileage, electric power, and the like.
In some embodiments, the controller 121 and the display device 12 may be independent devices, or may be integrated in the same device, which is not limited in particular by the embodiment of the present invention.
When the controller 11 and the display device 12 are integrated in the same apparatus, the data transmission between the controller 11 and the display device 12 is performed by data transmission between internal modules of the apparatus. In this case, the data transfer flow therebetween is the same as "in the case where the controller 11 and the display device 12 are independent of each other".
In the following embodiments provided in the present embodiment, the present embodiment will be described taking the example that the controller 11 and the display device 12 are provided independently of each other.
Fig. 6 is a flow diagram illustrating a display method according to some example embodiments. In some embodiments, the above-described display method may be applied to the controller 121 as shown in fig. 2, and may also be applied to the display apparatus 12 including the controller 121 or other similar devices. In the following, the embodiment of the present invention will be described with reference to the example in which the display method is applied to the controller.
S201, the controller acquires the positions of eyes of a driver through a sensor.
The sensor comprises a human eye recognition device, a distance detection device and a seat weight detection device. After receiving the weight data transmitted by the seat weight detection device, the controller determines that the driver is positioned on the driver seat, starts the human eye recognition device to recognize eyes of the driver, and detects the positions of the eyes of the driver according to the eyes of the driver recognized by the human eye recognition device through the distance detection device.
As another possible implementation, the controller acquires the position of the driver's eyes through a sensor.
The sensor can be an infrared matrix arranged at the top in the vehicle, and the controller can perform multi-infrared ranging through the infrared matrix to determine the position of eyes of a driver.
It should be noted that, triggering the controller to obtain the position of the eyes of the driver through the sensor may further be: after the display device is started, the controller controls the sensor to acquire the position of eyes of the driver.
S202, the controller determines the visible area of the display screen according to the position of eyes of the driver, the position of the shielding object and the position of the display screen.
The display screen is used for displaying information such as speed per hour, rotation speed, driving auxiliary information, mileage, oil consumption and the like, and the shielding object can be an object such as a steering wheel arranged between the display screen and eyes of a driver. The position of the shielding object and the position of the display screen are stored in the display device in advance.
As a possible implementation, the controller calculates a visible area of the driver's eyes on the display screen based on the position of the driver's eyes acquired by the sensor, and the position of the obstacle stored in the storage space of the display device and the position of the display screen.
It can be understood that the display device compares the calculated area of the visible area with the area of the display screen, and under the condition that the area of the visible area is smaller than the area of the display screen, the display device determines that a shielding area exists on the display screen; in the case where the area of the visible region is equal to the area of the display screen, the display device determines that the display screen is not blocked, and the driver can see the complete display screen.
By way of example, fig. 7 shows an application scenario of a display device. As shown in fig. 7, after the display device is started, the controller controls the human eye recognition device R to recognize the eyes of the driver, and the position of the eyes of the driver is determined by the distance detection device S. After the controller determines the position of the driver's eyes, the controller calculates the visible area of the driver's eyes on the display screen P according to the position of the driver's eyes, the pre-stored position of the steering wheel G, and the pre-stored position of the display screen P. Further, the controller may compare the calculated area of the visible area with the area of the display screen P, if the area of the visible area is smaller than the area of the display screen P, it is determined that the shielding area exists on the display screen P, and if the area of the visible area is equal to the area of the display screen P, it is determined that the driver can see the complete display screen P.
S203, the controller controls the display screen to display the first display object in the visible area.
Wherein, the display priority of the first display object is higher than the preset display priority.
It should be noted that the preset display priority may be set in the display device in advance by an operation and maintenance person of the display device.
For a specific implementation of this step, reference may be made to the following description of the embodiments of the present invention, which is not described herein in detail.
In one design, since the above embodiment is suitable for the driver to enter the vehicle or start the vehicle, but the possibility of adjusting the seat is also present during the driving process of the driver or in other states, the driver may shift the position of the head of the driver greatly after adjusting the seat, and the display screen may still be blocked by the blocking object. Therefore, in order to ensure that the driver can still see the complete display content displayed by the display screen after adjusting the seat, as shown in fig. 8, S202 provided by the embodiment of the present invention may specifically include the following S2021-S2024:
s2021, the controller acquires the position after the driver' S eyes are moved in the preset period.
The preset time period is a time period when the vehicle-mounted control system is in an on state.
The method for obtaining the position of the eyes of the driver by the controller in step S201 may refer to the method for obtaining the position of the eyes of the driver by the controller in the above step S201, and will not be described herein.
S2022, the controller determines the distance the driver' S eyes move within a preset time period.
As a possible implementation manner, the controller calculates a distance between the driver ' S eyes according to the position of the driver ' S eyes in the vehicle body after the driver ' S eyes are moved and the position of the driver ' S eyes determined by the controller in S201, that is, determines the distance of the driver ' S eyes movement.
S2023, the controller determines whether the distance traveled by the eyes of the driver is greater than a first threshold value within a preset time period.
As a possible implementation manner, after acquiring the distance of the eyes of the driver, the controller compares the distance with a preset first threshold value to judge whether the head of the driver is changed greatly.
The first threshold value may be set in the display device in advance by an operator of the vehicle-mounted control system.
It will be appreciated that the display means determines whether the driver's head has changed substantially by comparing the distance the driver's eyes have moved to the first threshold value. If the moving distance is smaller than the first threshold value, the head of the driver does not move greatly; if the distance of the movement is greater than the first threshold, the driver's head is indicated to be greatly moved.
S2024, under the condition that the preset condition is met, the controller determines the visible area of the display screen according to the position of eyes of the driver, the position of the shielding object and the position of the display screen.
Wherein the preset condition includes a distance traveled by the driver's eyes during a preset time period being greater than a first threshold.
In some embodiments, the preset conditions further include the display device being turned on in step S201.
It should be noted that, the method for determining the visible area of the display screen by the controller according to the position of the eyes of the driver, the position of the shielding object and the position of the display screen may refer to step S202, which is not described herein.
It can be appreciated that the distance that the eyes of the driver move in the preset time period is greater than the first threshold, that is, the head position of the driver is greatly changed, for example, the driver changes the driving posture and adjusts the driving seat, so as to ensure that the driver can view relatively important display contents such as a speed per hour meter, and the visible area on the display screen is determined again.
Subsequently, if there is a shielding area on the display screen, the display device executes the method in step S203, and controls the display screen to display the first display object in the visible area, so that after the position of the head of the driver is greatly changed, relatively important display contents such as a speed meter and the like can still be viewed.
In one design, in order to enable the driver to view other display objects except the first display object in the display screen in the visible area of the display screen, as shown in fig. 9, S203 provided by the embodiment of the present invention may further include the following S2031-S2032:
s2031, the controller determines whether the area of the visible region is greater than a second threshold.
As a possible implementation manner, the controller determines whether the area of the visible region is greater than the second threshold value according to the area of the visible region determined in the above step S202, compared with the preset second threshold value.
The second threshold value may be set in the display device in advance by an operator of the in-vehicle control system.
S2032, controlling, by the controller, the display screen to display the second display object in the visible region if the area of the visible region is greater than the second threshold.
The display priority of the second display object is lower than or equal to the preset display priority, and the second display object is other display objects except the first display object in the display screen.
As one possible implementation, the controller displays the first display object and the second display object in the visible region in a case where the area of the visible region is greater than the second threshold.
For example, the second threshold may be two-thirds of the area of the display screen, and in the case where the area of the visible region is greater than two-thirds of the area of the display screen, as shown in fig. 10, the controller adjusts the sizes of the first display object and the second display object, and controls the display screen to display the adjusted first display object and the adjusted second display object in the visible region, where the first display object is the adjusted display object in the region a, the second object is the display object in the region B except the region a, and the region C is the region where the display screen is blocked, and no display object is displayed in the region.
In practical applications, since the importance of different display objects is different, for example, the time rate meter is the most important, the most important display object must be always displayed in the visible region, and therefore, in one design, in order to avoid that the size of the important display object becomes small in the case that the visible region is small, the driver cannot clearly view the display object. As shown in fig. 11, S203 provided by the embodiment of the present invention may specifically further include the following S2033 to S2035:
s2033, the controller determines whether the area of the visible region is less than or equal to a second threshold.
The method for determining whether the area of the visible region is less than or equal to the second threshold by the controller may refer to step S2031, which is not described herein.
S2034, the controller divides the visible region into a first region and a second region.
The first area is used for fixing display objects with display priority higher than preset display priority, and the second area is used for alternately displaying other display objects except the display objects displayed in the fixed area.
As a possible implementation manner, the controller divides the visible area according to the display object with the display priority higher than the preset display priority to obtain the first area and the second area in order to ensure that the display object with the display priority higher than the preset display priority is better presented to the driver.
S2035, in a case where the area of the visible region is less than or equal to the second threshold, the controller controls the display screen to display the first display object in the first region of the visible region, and controls the display screen to alternately display the second display object and the third display object in the second region of the visible region.
The display priority of the second display object and the priority of the third display object are lower than or equal to the preset display priority.
For example, the second threshold may be two thirds of the area of the display screen, and the display device stores display priorities of the display objects in advance, for example, the first display object is a speed meter and a following situation, the display priority of the first display object is 3, the second display object is driving assistance information, the display priority of the second display object is 2, the third display object is mileage information and electric quantity, and the display priority of the third display object is 1, where the higher the value of the display priority is, the higher the display priority is indicated. The display device also stores a preset display priority, and the preset display priority is 2. In the case that the area of the visible area is less than or equal to two thirds of the area of the display screen, as shown in fig. 12 and 13, the first display object speed meter and the following situation are fixedly displayed in the first area, the second display object driving auxiliary information, and the third display object mileage information and electric quantity are alternately displayed in the second area, wherein the display object included in the area a is the first display object, the display object included in the area B is the second display object, the object displayed in the area C is the third display object, the area D is the area where the display screen is blocked, and no display object is displayed in the area.
The invention provides a display device, a display method, a vehicle and a storage medium, wherein the position of eyes of a driver is obtained through a sensor, a visible area of a display screen is determined according to the position of eyes of the driver, the position of a shielding object and the position of the display screen, and the display screen is controlled to display a first display object in the visible area, wherein the display priority of the first display object is higher than a preset display priority. The display device provided by the invention can display the display objects with higher display priority than the preset display priority in the visible area after the positions of eyes of the driver are acquired, so that the drivers with different heights can drive in a comfortable posture and can also view the display objects with higher display priority than the preset display priority on the display screen.
