[0030] The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate embodiments consistent with the present application and, together with the description, serve to explain the principles of the present application. DETAILED DESCRIPTION
[0031] In order to make the objectives, technical solutions and advantages of this application clearer, the implementation methods of this application will be further described in detail below with reference to the accompanying drawings.
[0032] Figure 1 A schematic diagram of a control system for an in-vehicle display screen provided by an exemplary embodiment of the present application is shown. The system includes a controller 101 and an in-vehicle display screen 102 .
[0033] The controller 101 is configured to receive vehicle control signals and to control the vehicle display screen 102. For example, upon receiving a preset type of vehicle control signal, the controller 101 controls the vehicle display screen 102 to activate the anti-peeping mode. For another example, the controller 101 controls the vehicle display screen 102 to deactivate the anti-peeping mode upon satisfying a preset termination condition.
[0034] The controller 101 may include a first memory and a first processor. The first memory stores a control program for an on-board display screen; the control program for the on-board display screen is called and executed by the first processor to implement the control method for the on-board display screen provided in this application. The first memory may include, but is not limited to, the following: random access memory (RAM), read-only memory (ROM), programmable read-only memory (PROM), erasable programmable read-only memory (EPROM), and electrically erasable programmable read-only memory (EEPROM).
[0035] In an optional embodiment, as Figure 2 As shown, the controller 101 may include a vehicle body controller 103 and a cockpit domain controller 104 .
[0036] The cockpit domain controller 104 and the onboard display screen 102 interact via an IIC (Inter-Integrated Circuit) bus, transmitting video images and other information in real time for display on the onboard display screen. Simultaneously, the cockpit domain controller 104 transmits vehicle control signals (such as turn signals or reverse signals) received from the vehicle body controller 103 to the onboard display screen 102 via an IIC signal. Upon receiving the preset vehicle control signal, the onboard display screen 102 automatically activates the anti-peeping function. Furthermore, the anti-peeping function can be manually set on and off through the settings on the cockpit domain controller 104. This function can also be implemented through voice control. For example, the cockpit domain controller 104 can collect and recognize the user's voice commands, and when the voice command indicates to turn the anti-peeping mode on / off, it controls the onboard display screen 102 to turn the anti-peeping mode on / off. The cockpit domain controller 104 receives the turn signal and gear position signal sent from the vehicle body controller 103 and sends them to the onboard display screen via LVDS (Low Voltage Differential Signaling).
[0037] The body controller 103 can send the received vehicle control signal (such as a turn signal or a reverse signal) to the cockpit domain controller 104. The body controller 103 mainly receives the turn signal and the gear position signal and sends the signal to the cockpit domain controller 104 in a timely manner.
[0038] In addition, the system may also include a steering switch 105 and a gear switch 106. The steering switch 105 is used to trigger a steering signal and send it to the body controller 103. The steering switch 105 is placed on the vehicle's steering wheel. The driver operates the steering wheel to control the vehicle's driving direction. When the steering wheel turns, the steering switch 105 in the steering wheel can generate a steering signal, which is sent to the body controller 103 via the CAN (Controller Area Network) bus. The steering signal includes at least one of the following information: steering direction and steering angle.
[0039] The gear switch 106 is used to send a gear position signal to the vehicle body controller 103 when the gear is switched. The gear switch 106 is used to adjust the vehicle's gear position. The gear position can include at least one of the following: forward gear, reverse gear, neutral gear, and park gear. When the driver adjusts the gear switch 106, the gear switch 106 sends a gear position signal to the vehicle body controller 103 via the CAN bus. The gear position signal includes the vehicle's current gear position.
[0040] The vehicle-mounted display screen 102 is an important component of the vehicle's intelligent cockpit, providing functions such as information interaction, entertainment, navigation, and driver assistance. There can be one or more vehicle-mounted display screens. When a vehicle includes multiple vehicle-mounted display screens, the controller can control all or some of the vehicle-mounted display screens to enable anti-peeping mode.
[0041] With the development of intelligent cockpits in cars, the types of in-vehicle displays are becoming increasingly diverse. For example, in-vehicle displays can include at least one of the following: a central control display (integrated vehicle control and entertainment systems), an instrument panel screen (replacing traditional mechanical instruments), a driver's display screen (providing driving information), a passenger display screen (focusing on audio and video entertainment), a rear-seat display screen (for passenger use), a head-up display (for projecting key information onto the windshield), a rearview mirror display screen (replacing traditional rearview mirrors), a door control screen (adjusting windows / seats), a temperature control screen (for air conditioning control), a steering wheel touch screen (for quick operation), an armrest screen (for comfort function adjustment), a passenger sunshade screen (integrated display and sunshade), a ceiling screen (rear-seat entertainment), a headrest screen (personalized audio and video), and a laser projection (large-scale virtual display). Together, they form a multi-screen intelligent interactive ecosystem.
[0042] The vehicle-mounted display screen 102 supports active anti-peeping technology. For example, Figure 3 As shown, the vehicle-mounted display screen has an anti-peeping module, which places a POD 108 (Privacy Optical Device) in front of a display panel 107 (e.g., LCD (Liquid Crystal Display) panel). The POD 108 includes a liquid crystal switch panel and an additional polarizer, and uses a collimated backlight seat light source. The rubbing direction of the liquid crystal switch panel, the transmission axis of the additional polarizer, and the display panel color filter polarizer are arranged in parallel. The rubbing direction of the liquid crystal switch panel is the pre-orientation direction of the liquid crystal molecules on the surface of the substrate, which is determined by a mechanical rubbing process and determines the initial arrangement angle of the liquid crystal molecules. The transmission axis is the polarization direction of light allowed to pass through the additional polarizer, and the additional polarizer must be aligned parallel to the color filter polarizer of the display panel.
[0043] like Figure 4 As shown, when the privacy function is off, the liquid crystal molecules 109 remain parallel to the polarizer, so that the transmitted light at various incident angles is not affected, and the screen presents a wide viewing angle mode.
[0044] like Figure 5As shown, when the privacy protection function is turned on (ON), the liquid crystal molecules 109 in the liquid crystal switch panel begin to tilt when voltage is applied, but the tilt plane remains parallel to the additional polarizer. Therefore, light near the optical axis of the vehicle display is not affected by the liquid crystal switch panel. However, light propagating at large angles is blocked by the additional polarizer, resulting in a dark field of view on both sides of the screen, effectively preventing others from viewing the screen from the side.
[0045] Active privacy protection technology for automotive displays integrates an optical module consisting of a liquid crystal switch panel and an additional polarizer in front of the LCD panel, combined with a directional collimated backlight to achieve dynamic viewing angle control. This allows precise control of the interaction between the alignment of the liquid crystal molecules and polarized light. When privacy protection is off, the liquid crystal molecules maintain their initial parallel alignment, allowing light to penetrate freely at all viewing angles. However, when a voltage is applied to activate privacy protection mode, the liquid crystal molecules controllably tilt, altering their polarization state to selectively block incident light at wide angles, allowing only frontal light along the optical axis to pass through.
[0046] It's important to note that the anti-peeping angle of the car display's privacy mode is adjustable. By dynamically adjusting the applied voltage, the tilt angle of the liquid crystal molecules can be precisely controlled, allowing for flexible adjustments to the privacy protection zone. Increasing the voltage increases the tilt of the liquid crystal, enhancing the polarization blocking effect and tightening the privacy protection angle to effectively prevent side-viewing. Lowering the voltage, on the other hand, reduces the molecular tilt, widening the viewing angle to accommodate shared viewing. This voltage-tilt control mechanism, combined with the directional enhancement of the collimated backlight, enables car displays to provide highly flexible visibility management solutions.
[0047] For example, to reduce the driver's need to adjust the anti-peeping angle, the anti-peeping angle of the vehicle display screen 102 anti-peeping mode can be determined based on the actual vehicle layout. Through a large number of experiments, the optimal anti-peeping angle of the vehicle display screen in different vehicle models can be tested. In addition, at least two anti-peeping angles can be provided to the driver based on the driver's height. In actual application, the appropriate gear (anti-peeping angle) anti-peeping mode can be selected based on the driver's height. For example, after testing, three gear anti-peeping modes were defined based on the requirements of 95% of drivers, and the anti-peeping modes of different gears correspond to different anti-peeping angles.
[0048] Figure 6 This is a flow chart of a method for controlling a vehicle display screen provided by an exemplary embodiment of the present application. Figure 1 In the control system of the vehicle-mounted display screen shown, for example, the method is executed by the control 101. The method includes the following steps.
[0049] Step 210: Receive a first vehicle control signal, where the first vehicle control signal is generated according to a driving operation of the vehicle and is used to determine a driving state of the vehicle.
[0050] The first vehicle control signal is a signal generated in response to a driver's operation of driving the vehicle. For example, the first vehicle control signal changes the vehicle's driving state. For example, it changes the vehicle from a forward state to a reverse state, or from a straight-ahead state to a turning state, or from a stationary state to a driving state, etc.
[0051] Step 220: When the first vehicle control signal includes a target type of vehicle control signal, the anti-peeping mode of the vehicle display screen is activated; the anti-peeping mode is used to limit the light of the vehicle display screen from propagating in a target direction; the target direction is the direction in which the vehicle-mounted components with reflective properties are located.
[0052] Among them, the car display screen is an anti-peeping display screen that supports anti-peeping angle adjustment; the car display screen includes a liquid crystal switch panel and a polarizer; the liquid crystal switch panel and the polarizer are used to adjust the light propagation direction of the car display screen.
[0053] For example, since the reflection of the vehicle display screen on the glass or mirror will affect the driver's line of sight in some driving conditions, when the vehicle control signal corresponding to this driving condition is received, the anti-peep mode of the vehicle display screen needs to be enabled to prevent the vehicle display screen from producing reflective images on the glass or mirror.
[0054] The vehicle-mounted component with reflective properties may be at least one of a front windshield, a rear windshield, a side windshield, a rearview mirror, and a side mirror.
[0055] In an optional embodiment, the vehicle includes multiple on-board display screens, some of which (for example, one or more display screens) will affect the driver's field of view under a certain driving state of the vehicle. The controller can activate the anti-peep mode of these on-board display screens when the vehicle is driving in this driving state.
[0056] In an optional embodiment, since drivers of different heights have different fields of view, the anti-peeping angle of the vehicle display screen can be adjusted according to the driver's height. Optionally, the light propagation direction restricted by the anti-peeping mode is determined based on the driver's height; or, the light propagation direction restricted by the anti-peeping mode is determined based on the seat height and / or fore-aft position of the driver's seat; or, the light propagation direction restricted by the anti-peeping mode is determined based on the identified position of the driver's eyes.
[0057] For example, the driver's seat has multiple height levels, each of which corresponds to an anti-peeping mode with different anti-peeping angles. The controller can activate the anti-peeping mode corresponding to the height level according to the driver's seat height level.
[0058] It should be noted that in different driving conditions, different in-vehicle displays will affect the driver's field of view, and the angles of light that affect them will also vary. Experiments can be conducted to test which in-vehicle displays will have what kind of visual impact in different driving conditions, and to set the corresponding anti-peeping mode accordingly. That is, the types of in-vehicle displays that require anti-peeping mode to be enabled can vary in different anti-peeping modes, and the anti-peeping angles that are enabled can also vary.
[0059] Optionally, the experiment measures the sight line influence results of the vehicle under at least one vehicle control signal; the sight line influence results include at least one of the following: a vehicle display screen with sight line influence, and a sight line influence direction corresponding to at least one vehicle display screen with sight line influence.
[0060] A correspondence between at least one vehicle control signal and at least one anti-peeping mode is configured according to the line of sight influence result; each of the at least one anti-peeping mode is used to adjust the vehicle-mounted display screen with line of sight influence according to the line of sight influence direction.
[0061] Subsequently, in a case where the first vehicle control signal includes a vehicle control signal of the target type, the anti-peeping mode corresponding to the first vehicle control signal is activated according to the corresponding relationship.
[0062] Among them, the vehicle-mounted display screens that have visual impact include at least one of the following: central control display screen, instrument panel flat panel, driver display screen, co-driver display screen, rear display screen, head-up display HUD, rearview mirror display screen, door control screen, temperature control screen, reverse wheel touch screen, armrest screen, co-driver sunshade screen, ceiling screen, headrest screen, and laser projection.
[0063] Step 230: If the end condition is met, turn off the anti-peeping mode of the vehicle display screen; the end condition is used to determine that the driving state indicated by the first vehicle control signal is ended.
[0064] For example, after the preset driving state ends, the anti-peeping mode of the vehicle display screen can be turned off to prevent the anti-peeping mode from affecting the user's viewing experience.
[0065] It should be noted that the automatic anti-peeping mode adjustment of the vehicle display can also be set through the voice function of the cockpit domain controller and the setting items of the user interface. If you want to realize automatic anti-peeping mode adjustment according to the turn signal or gear signal, you need to set the anti-peeping mode switch to the on state.
[0066] In summary, the method provided in the embodiments of the present application utilizes an in-vehicle display screen that supports active anti-peeping display technology. By activating the anti-peeping mode of the in-vehicle display screen while the driver is driving the vehicle, the method prevents the reflection of the in-vehicle display screen on the glass or mirror from affecting the driver's field of vision. The anti-peeping mode of the in-vehicle display screen is automatically adjusted according to the vehicle's environment. For example, the in-vehicle display screen automatically activates the anti-peeping mode by receiving the vehicle's turn signal or reverse signal. In the anti-peeping state, the in-vehicle display screen reduces its impact on the side windshield or rearview mirror, reducing the interference of reflected images on the driver's field of vision.
[0067] In an optional embodiment, the vehicle control signal may be a reverse signal.
[0068] Figure 7 This is a flow chart of a method for controlling a vehicle display screen provided by an exemplary embodiment of the present application. Figure 1 The control system of the vehicle display screen shown in FIG. 1 is, for example, executed by the controller 101. Figure 6 In the illustrated embodiment, step 220 includes step 221 , and step 230 includes step 231 .
[0069] Step 210: Receive a first vehicle control signal, where the first vehicle control signal is generated according to a driving operation of the vehicle and is used to determine a driving state of the vehicle.
[0070] For example, in response to an operation of engaging the reverse gear, the gear switch generates a reverse signal and sends the reverse signal as the first vehicle control signal to the controller. The controller receives the reverse signal sent by the gear switch.
[0071] In an optional embodiment, the reverse signal may include the deflection angle of the side mirror (left and / or right side mirror). The controller may determine the required anti-peeping angle based on the deflection angle of the side mirror and activate the anti-peeping mode corresponding to the anti-peeping angle. The correspondence between the side mirror deflection angle and the anti-peeping angle may be obtained by looking up a table, and the correspondence table may be obtained through experimental measurement.
[0072] Step 221: When the first vehicle control signal is a reversing signal, start the first anti-peeping mode of the vehicle display screen.
[0073] Among them, the first anti-peep mode is used to limit the light of the vehicle display screen from propagating toward the first type of target direction; the first type of target direction includes the direction of at least one component among the rearview mirror, side mirror, and side windshield.
[0074] Step 231: When a second vehicle control signal is received, the anti-peeping mode of the vehicle display screen is turned off.
[0075] The second vehicle control signal includes a gear shift signal other than a reverse signal. For example, the second vehicle control signal may be a forward signal, a neutral signal, or a parking signal.
[0076] Optionally, after receiving the second duration of the second vehicle control signal, the anti-peeping mode of the vehicle display screen is turned off.
[0077] For example, when the vehicle's display screen receives a gear signal and determines that it is in reverse gear, it automatically activates anti-peeping mode. When anti-peeping mode is activated, the display screen's lighting angle changes, reducing the light reaching the side windshield and rearview mirror. The image displayed on the display screen is no longer reflected on the windshield or rearview mirror, allowing the driver to more clearly observe the situation behind the vehicle and reverse safely. When a P / N / D gear signal is received, the display screen deactivates anti-peeping mode after a 3-second delay.
[0078] In summary, the method provided in this embodiment utilizes an in-vehicle display screen that supports active anti-peeping display technology. When the driver is reversing, the in-vehicle display screen's anti-peeping mode is activated to prevent glare from the screen on glass or mirrors from obstructing the driver's field of vision. The in-vehicle display screen's anti-peeping mode is automatically adjusted based on the vehicle's surroundings. For example, the in-vehicle display screen automatically activates anti-peeping mode upon receiving a reverse signal from the vehicle. In this anti-peeping state, the in-vehicle display screen's impact on the side windshield or rearview mirror is reduced, minimizing interference from reflected images with the driver's field of vision.
[0079] In an optional embodiment, the vehicle control signal may be a turn signal.
[0080] Figure 8 This is a flow chart of a method for controlling a vehicle display screen provided by an exemplary embodiment of the present application. Figure 1 The control system of the vehicle display screen shown in FIG. 1 is, for example, executed by the controller 101. Figure 6 In the illustrated embodiment, step 220 includes step 222 , and step 230 includes step 232 .
[0081] Step 210: Receive a first vehicle control signal, where the first vehicle control signal is generated according to a driving operation of the vehicle and is used to determine a driving state of the vehicle.
[0082] For example, in response to a steering operation of the steering wheel, the steering switch generates a steering signal, and sends the steering signal as a first vehicle control signal to the controller. The controller receives the steering signal sent by the steering switch.
[0083] In an optional embodiment, the turn signal may include a steering angle, and the controller may determine the required privacy protection angle based on the steering angle and activate the privacy protection mode corresponding to the privacy protection angle. The correspondence between the steering angle and the privacy protection angle may be obtained by looking up a table, and the correspondence table may be obtained through experimental measurement.
[0084] Step 222: When the first vehicle control signal is a turn signal, start the second anti-peeping mode of the vehicle display screen.
[0085] Among them, the second anti-peep mode is used to limit the light of the vehicle display screen from propagating toward the second type of target direction; the second type of target direction includes the direction of at least one component of the side mirror and the side windshield.
[0086] Furthermore, a privacy protection mode corresponding to the privacy protection angle can be activated based on the steering angle. When the first vehicle control signal is a turn signal, the second privacy protection mode of the vehicle display is activated based on the steering direction and steering angle indicated by the turn signal. The light propagation direction restricted by the second privacy protection mode is determined based on the steering direction and steering angle.
[0087] That is, for the same in-vehicle display screen, the anti-peeping angle after the anti-peeping mode is enabled may be different under different steering directions and / or steering angles.
[0088] Step 232: If the turn signal is not received again within the first time period, turn off the anti-peeping mode of the vehicle display screen.
[0089] For example, after the vehicle-mounted display screen receives a turn signal, the anti-peep mode is automatically turned on. At this time, the luminous angle of the vehicle-mounted display screen changes, and the light in the direction of the side windshield or rearview mirror is reduced, so there will be no side windshield imaging or rearview mirror imaging, which will affect the driver's observation of the vehicle's surrounding environment when turning or changing lanes, and safe driving can be achieved. When the vehicle-mounted display screen does not receive a turn signal, the anti-peep function is turned off after a delay of 3 seconds.
[0090] In summary, the method provided in this embodiment utilizes an in-vehicle display screen that supports active anti-peeping display technology. By activating the anti-peeping mode of the in-vehicle display screen while the driver is steering the vehicle, this prevents glare from the in-vehicle display screen on glass or mirrors from affecting the driver's field of vision. The anti-peeping mode of the in-vehicle display screen is automatically adjusted based on the vehicle's surroundings. For example, the in-vehicle display screen automatically activates anti-peeping mode based on the vehicle's turn signals. In this anti-peeping mode, the in-vehicle display screen's impact on the side windshield or rearview mirror is reduced, minimizing interference of reflected images with the driver's field of vision.
[0091] Figure 9 This is a schematic diagram of the structure of a control device for an in-vehicle display screen provided by an exemplary embodiment of the present application. The device includes:
[0092] A receiving module 801 is configured to receive a first vehicle control signal, where the first vehicle control signal is generated based on a vehicle driving operation and is used to determine a vehicle driving state;
[0093] an anti-peeping module 802 configured to activate an anti-peeping mode for the vehicle display screen when the first vehicle control signal includes a target-type vehicle control signal; the anti-peeping mode is configured to restrict light from the vehicle display screen from propagating in a target direction; the target direction is a direction in which a vehicle-mounted component having a reflective property is located;
[0094] The anti-peeping module 802 is used to turn off the anti-peeping mode of the vehicle display screen when an end condition is met; the end condition is used to determine that the driving state indicated by the first vehicle control signal ends.
[0095] In an optional embodiment, the anti-peeping module 802 is configured to activate a first anti-peeping mode of the vehicle display screen when the first vehicle control signal is a reversing signal;
