Description

Technical Field

[0001] The present application relates to the technical field of vehicle information display, and in particular to a display control method, device, computer equipment, computer-readable storage medium and computer program product for a vehicle-mounted screen. Background Art

[0002] Motion sickness, or motion sickness, is caused by information conflicts between the human vestibular system, visual system, and proprioceptive system. During the ride, the passenger's visual system perceives the relatively static environment inside the car, while the vestibular system perceives dynamic changes such as acceleration, deceleration, and turning of the vehicle. This inconsistent information causes confusion in the brain, which in turn causes motion sickness symptoms. The traditional way to solve the problem of motion sickness is to wear special anti-motion sickness glasses. The anti-motion sickness glasses have blue liquid injected into the frame. During the movement of the vehicle, the liquid will flow with the speed, turning, etc., giving the user a visual motion reference system to prevent motion sickness. However, users need to wear an extra pair of glasses to view the screen, which makes it very inconvenient. Summary of the invention

[0043] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0044] The display control method of the vehicle screen provided in the embodiment of the present application can be applied to Figure 1 In the application environment shown. Among them, the vehicle terminal 102 communicates with the server 104 through the network. The data storage system can store the data that the server 104 needs to process. The data storage system can be integrated on the server 104, or it can be placed on the cloud or other network servers. The vehicle terminal 102 displays the visual element in the edge area of ​​the vehicle screen; the vehicle terminal 102 determines the moving distance and moving direction of the target visual element according to the vehicle operation state of the vehicle; the target visual element is a visual element that matches the vehicle operation state; the vehicle terminal 102 controls the target visual element to move along the moving direction in the edge area according to the moving distance. Among them, the vehicle terminal 102 may include but is not limited to a display control unit (Display Head Unit, DHU), which can be used to obtain the vehicle operation state of the vehicle and can control the display of the vehicle screen. The server 104 can be an independent physical server, or a server cluster or distributed system composed of multiple physical servers, or a cloud server that provides cloud computing services.

[0045] In an exemplary embodiment, Figure 2 As shown, a display control method for a vehicle-mounted screen is provided, and the method is applied to Figure 1 The vehicle terminal in the example is used to illustrate, including:

[0046] Step S202, displaying visual elements in the edge area of ​​the vehicle screen.

[0047] Among them, the visual elements can be elements with dynamic effects such as halos, lines, icons or gradient colors. The visual elements have good recognition in the edge area of ​​the vehicle screen and do not affect the main content of the screen. Exemplarily, if the visual element is a halo, the effect of the halo can well simulate the changes in light and shadow in the direction of the vehicle's travel and enhance the sense of direction and speed. Optionally, the shape of the halo can be circular or square, without specific limitation. The movement of the visual element can represent the change in the movement of the vehicle and the change in the inertia of the human body.

[0048] In a specific implementation, the edge area of ​​the vehicle screen can be divided into four main edge areas: top, bottom, left, and right. Visual elements can be displayed in edge areas of all directions, or only in edge areas of two directions perpendicular to each other, for example, in edge areas of the bottom and right directions.

[0049] In actual applications, passengers can adjust the display effects of visual elements through the user interface of the in-vehicle screen, such as enabling / disabling visual elements, adjusting the style, color, brightness, etc. of visual elements to meet different visual comfort requirements. In addition, different visual modes of visual elements can be designed according to user preferences, such as "simple mode" only displays basic movement directions, while "dynamic mode" provides richer movement status feedback.

[0050] In actual applications, the on-board terminal can automatically turn on the anti-motion sickness function when the vehicle movement is detected, and control the on-board screen to display visual elements in the edge area; alternatively, passengers can turn on the visual effect switch for motion sickness reduction through the user interface of the on-board screen, and the on-board terminal will control the on-board screen to display a halo in the edge area.

[0051] Step S204, determining the moving distance and moving direction of the target visual element according to the vehicle operation state of the vehicle.

[0052] The vehicle operation state may include motion state information obtained by analyzing the motion data collected by the vehicle sensors (such as wheel speed sensors, acceleration sensors, gyroscopes, etc.) by the vehicle terminal, such as speed, acceleration, steering wheel steering angle, accelerator pedal depression depth, brake pedal depression depth, etc. The vehicle operation state can be used to characterize the vehicle's motion state, such as acceleration, deceleration, turning, U-turn, lane change, etc.

[0053] The target visual element is a visual element that matches the vehicle operation state.

[0054] As an example, the vehicle terminal can determine the brightness and color of the visual element according to the vehicle operation state, and generate the target visual element according to the brightness and color. For example, when the vehicle accelerates, the brightness of the halo increases and the color tends to be warm; when the vehicle decelerates, the brightness decreases and the color changes to a cool color.

[0055] As another example, the vehicle terminal may determine a target edge region among multiple edge regions according to the vehicle operation state of the vehicle, and determine a visual element in the target edge region as a target visual element. For example, when the vehicle is turning, the vehicle terminal may determine the edge regions in the upper and lower directions as the target edge regions, or may determine only the edge region in the lower direction as the target edge region; when the vehicle is moving straight, the vehicle terminal may determine the edge regions in the left and right directions as the target edge regions, or may determine only the edge region in the right direction as the target edge region.

[0056] The vehicle terminal determines the moving distance and moving direction of the target visual element according to the vehicle operation state of the vehicle. As an example, the vehicle terminal can control the target visual element to move downward when the vehicle accelerates, and control the target visual element to move upward when the vehicle decelerates. At the same time, the moving distance of the target visual element can be calculated according to the vehicle acceleration, and the moving distance is positively correlated with the vehicle acceleration; the vehicle terminal can control the target visual element to move to the right when the vehicle turns left, and control the target visual element to move to the left when the vehicle turns right. At the same time, the moving distance of the target visual element can be calculated according to the vehicle steering wheel angle, and the moving distance is positively correlated with the vehicle steering wheel angle.

[0057] As another example, the vehicle-mounted terminal may perform weighted calculation on multiple values ​​such as speed, acceleration, steering wheel angle, etc. to determine the moving distance.

[0058] As another example, after the vehicle terminal preliminarily determines the moving distance according to at least one value of the speed, acceleration, and steering wheel angle, it can add an additional value to the preliminarily determined moving distance to obtain an updated moving distance when the acceleration of the target visual element is greater than the acceleration threshold or the change speed of the steering wheel angle of the target visual element is greater than the angle threshold. For example, when the vehicle is in an intense operation state such as rapid acceleration or sharp turn, the vehicle terminal can increase the moving distance accordingly to highlight the feedback effect on the vehicle operation state.

[0059] Optionally, the vehicle-mounted terminal can also determine the moving speed of the target visual element based on the vehicle speed, which is positively correlated with the moving speed of the target visual element, and then determine the moving distance of the target visual element based on the product of the moving time and the moving speed; wherein the moving time can be a preset time value calculated from each time the vehicle switches its motion state (for example, from acceleration to deceleration).

[0060] Step S206: Control the target visual element to move along the moving direction in the edge area according to the moving distance.

[0061] In a specific implementation, when the vehicle is stationary, the visual element can be located in the center of the edge area. When the vehicle is in motion, the vehicle terminal controls the target visual element to move from the center to the moving direction in the edge area according to the moving distance.

[0062] Optionally, the vehicle terminal can control the target visual element to move along the moving direction in the edge area according to the moving distance through a smooth control algorithm. The smooth control algorithm may include an easing algorithm, an interpolation algorithm, etc., to ensure that the movement of the visual element smoothly transitions from one state to the next. For example, when the vehicle changes from an acceleration state to a deceleration state, the movement speed of the visual element gradually slows down, and then turns to reverse movement, providing passengers with a natural and coherent visual experience.

[0063] Optionally, the target visual element may move at a uniform speed, or at a fixed speed, which may be a custom parameter value.

[0064] It can be seen that the dynamic visual elements (such as the movement of the halo at the edge of the screen) are used to simulate the movement trajectory of the vehicle, providing users with intuitive visual feedback. This visual feedback helps reduce the conflict between the user's vision and balance sense during the ride, thereby effectively alleviating motion sickness symptoms.

[0065] In the above-mentioned display control method of the vehicle screen, a visual element is displayed in the edge area of ​​the vehicle screen; by acquiring the vehicle operation status of the vehicle, the moving distance and moving direction of the target visual element are determined, and the target visual element is a visual element that matches the vehicle operation status; the target visual element is controlled to move along the moving direction in the edge area according to the moving distance. By displaying the visual element in the edge area of ​​the vehicle screen and adjusting the moving distance and moving direction of the visual element in real time according to the vehicle operation status, a dynamic visual compensation image synchronized with the vehicle motion status is generated and displayed in real time, so that the passenger's visual system can receive motion information consistent with the vestibular system, thereby alleviating or eliminating motion sickness symptoms, and there is no need for passengers to wear anti-motion sickness glasses, which improves the comfort of riding and the convenience of anti-motion sickness.

[0066] In order to facilitate the understanding of those skilled in the art, Figure 3A timing diagram of a display control method for an in-vehicle screen is provided as an example. Passengers can find the "anti-motion sickness function" option in the settings menu of the in-vehicle infotainment system and manually switch the state to "on" or "off"; alternatively, passengers can enable the anti-motion sickness function through voice commands; alternatively, passengers can remotely enable the anti-motion sickness function through a mobile phone application before getting on the bus or during the journey. The display control unit of the in-vehicle terminal can determine how the corresponding visual elements change according to the data changes of the in-vehicle sensors, and output the results to the in-vehicle screen after determining the change plan. The in-vehicle screen displays the changes of the visual elements and feeds back to the passengers watching the in-vehicle screen.

[0067] In another embodiment, the edge area includes a longitudinal edge area and a transverse edge area, and determining a moving distance and a moving direction of the target visual element according to a vehicle operation state of the vehicle includes:

[0068] According to the vehicle's driving direction in the vehicle operating state, a visual element in the longitudinal edge area or the lateral edge area is determined as a target visual element; according to the degree of vehicle state change in the vehicle operating state, a moving distance of the target visual element is determined; according to the direction of vehicle state change in the vehicle operating state, a moving direction of the target visual element is determined.

[0069] The vehicle's driving direction may include changes in driving routes such as forward, backward, left turn and right turn.

[0070] The longitudinal edge area may refer to an area corresponding to at least one of the left and right edges of the vehicle-mounted screen, which is used to display the vehicle's motion state changes in the front and rear directions, such as acceleration or deceleration. The transverse edge area may refer to an area corresponding to at least one of the upper and lower edges of the screen, which is used to reflect the vehicle's transverse changes, such as turning left or right.

[0071] For example, when the vehicle is moving forward or backward, the visual elements in the longitudinal edge area can be determined as the target visual elements. When the vehicle turns left or right, the visual elements in the transverse edge area can be selected as the target. By dividing the edge area into the longitudinal edge area and the transverse edge area, and determining the visual elements in the longitudinal edge area or the transverse edge area as the target visual elements according to the driving direction of the vehicle, it can be closer to the real driving experience and provide passengers with more directional visual feedback.

[0072] The degree of change in the vehicle state may refer to the magnitude of the change when the vehicle accelerates, decelerates or turns, and may be represented by the magnitude of the acceleration or the magnitude of the steering wheel angle.

[0073] The direction of the vehicle state change may refer to the specific direction of the vehicle state change, such as the direction of acceleration and the direction of change of the vehicle steering wheel angle. For example, acceleration (longitudinal acceleration forward), deceleration (longitudinal acceleration backward), left turn (lateral acceleration to the left or the direction of change of the vehicle steering wheel angle to the left), right turn (lateral acceleration to the right or the direction of change of the vehicle steering wheel angle to the right), etc.

[0074] In the specific implementation, the vehicle terminal determines the moving distance of the target visual element according to the degree of vehicle state change in the vehicle operation state. When the vehicle accelerates or decelerates, the moving distance of the target visual element can be dynamically adjusted according to the magnitude of the acceleration. The greater the acceleration, the longer the moving distance of the target visual element. When the vehicle turns, the moving distance of the target visual element can be controlled according to the magnitude of the steering wheel angle. The greater the steering wheel angle, the greater the moving distance of the target visual element. It can be seen that the dynamic adjustment of the moving distance can provide a more realistic visual feedback effect under different driving conditions, ensuring that the changes in the visual elements match the actual movement state of the vehicle.

[0075] In a specific implementation, the vehicle terminal determines the moving direction of the target visual element according to the direction of the vehicle state change in the vehicle operation state. When the vehicle accelerates forward (the direction of the longitudinal acceleration is forward), the moving direction of the target visual element is determined to be downward; when the vehicle decelerates forward (the direction of the longitudinal acceleration is backward), the moving direction of the target visual element is determined to be upward; when the vehicle turns left (the direction of the lateral acceleration is left), the moving direction of the target visual element is determined to be right; when the vehicle turns right (the direction of the lateral acceleration is right), the moving direction of the target visual element is determined to be left. It can be seen that the moving direction control based on the vehicle's motion state makes it easier for passengers to understand the vehicle's motion trajectory and reduce the feeling of motion sickness caused by the lack of motion reference.

[0076] Further, in another embodiment, according to the vehicle driving direction in the vehicle operating state, determining the visual element in the longitudinal edge area or the transverse edge area as the target visual element includes:

[0077] When the vehicle is traveling in a straight line, the visual elements in the longitudinal edge area are determined as target visual elements; when the vehicle is traveling in a turning direction, the visual elements in the transverse edge area are determined as target visual elements.

[0078] Optionally, the longitudinal edge region may be an edge region at the right side of the vehicle screen, and the transverse edge region may be an edge region at the lower side of the vehicle screen. There may be an intersection between the longitudinal edge region and the transverse edge region.

[0079] In order to facilitate the understanding of those skilled in the art, Figure 4 A schematic diagram of a target visual element is provided as an example. It can be seen that the vehicle screen 400 includes a longitudinal edge area 402 and a transverse edge area 404 , and visual elements are displayed in the longitudinal edge area 402 and the transverse edge area 404 , respectively.

[0080] It can be seen that the longitudinal edge area 402 extends longitudinally in the vehicle screen, and when the vehicle is traveling in a straight line, the longitudinal movement of the visual elements in the longitudinal edge area 402 can well simulate the state of the vehicle traveling forward and backward. Similarly, the transverse edge area 404 extends transversely in the vehicle screen, and when the vehicle is traveling in a turning direction, the transverse movement of the visual elements in the transverse edge area 404 can well simulate the state of the vehicle turning left or right.

[0081] The technical solution of this embodiment accurately selects which edge area's visual elements to control to move according to the vehicle's driving direction (straight or turning), thereby providing passengers with a more intuitive visual feedback effect. By visually perceiving the vehicle's acceleration, deceleration, turning and other states, the discomfort caused by the inconsistency between the sense of motion and the visual information is reduced, thereby improving the riding experience.

[0082] In another embodiment, when the vehicle is traveling in a straight line, the degree of vehicle state change includes vehicle acceleration; determining the moving distance of the target visual element based on the degree of vehicle state change in the vehicle operating state includes: determining the moving distance of the target visual element based on the vehicle acceleration and the acceleration coefficient; the acceleration coefficient is determined based on the resolution of the vehicle screen.

[0083] Among them, in order to ensure that the movement of visual elements is within the appropriate distance range on the screen, the acceleration value needs to be multiplied by an acceleration coefficient to adjust the moving distance. The acceleration coefficient is related to the resolution of the vehicle screen. For example, a high-resolution screen can support more delicate movements, so the acceleration coefficient is relatively small, while a low-resolution screen may require a larger acceleration coefficient to ensure that the movement of visual elements is clearly visible. For example, assuming that the vehicle accelerates forward, the acceleration is 2 meters per second squared, the visual element needs to slide to the bottom, and the screen resolution is 1980*1200, then the acceleration coefficient can be 600.

[0084] In a specific implementation, when the vehicle is traveling in a straight line, the visual element in the longitudinal edge area is determined as the target visual element, and the moving distance of the target visual element is determined according to the product of the vehicle acceleration and the acceleration coefficient. The moving distance can be expressed as:

[0085] d1=a*tempZ;

[0086] Wherein, d1 is the longitudinal moving distance of the target visual element when the vehicle is traveling in a straight line; a is the acceleration coefficient; and tempZ is the acceleration in the longitudinal direction of the vehicle.

[0087] The technical solution of this embodiment uses vehicle acceleration and screen resolution to determine the moving distance of visual elements to provide more natural and accurate dynamic visual feedback, helping passengers to better perceive the acceleration and deceleration status of the vehicle, thereby alleviating motion sickness and improving the riding experience.

[0088] In another embodiment, when the vehicle is turning, the degree of vehicle state change includes vehicle speed and vehicle steering wheel angle; determining the moving distance of the target visual element according to the degree of vehicle state change in the vehicle operation state includes:

[0089] The moving distance of the target visual element is determined according to the sum of the products of the vehicle speed and the vehicle steering wheel angle and the corresponding weights.

[0090] The vehicle speed indicates the speed of the vehicle. The faster the vehicle speed, the longer the moving distance of the visual element, so as to more significantly convey the sense of speed. The steering wheel angle reflects the steering amplitude of the vehicle. The larger the steering angle, the greater the steering amplitude of the vehicle and the longer the moving distance of the visual element. The vehicle speed and the vehicle steering wheel angle can affect the moving distance of the visual element in the lateral edge area.

[0091] In a specific implementation, vehicle speed and steering wheel angle have different effects on determining the moving distance of visual elements, so their respective weights are set. Optionally, the weight of speed can be smaller than the weight of steering wheel angle, so that the steering wheel angle has a greater impact on the movement of visual elements when turning, so as to highlight the visual effect of steering. Or, optionally, the vehicle terminal can dynamically adjust the weight according to the driving environment and driving status. For example, when driving at low speed on urban roads, the weight of the steering wheel angle can be greater than the weight of speed, so that the visual elements can respond more obviously to the steering operation; when driving at high speed on a highway, the speed weight can be increased so that the speed weight is greater than the steering wheel weight, so that the speed is more significant in the visual feedback.

[0092] In a specific implementation, when the vehicle is turning, the visual element in the lateral edge area is determined as the target visual element, and the moving distance of the target visual element is determined according to the sum of the product of the vehicle speed and the vehicle steering wheel angle and the corresponding weights. The moving distance can be expressed as:

[0093] d2=g*(m*x+n*y);

[0094] Where d2 is the lateral movement distance of the target visual element when the vehicle is turning; g is a constant coefficient, which can be a system preset value; x is the vehicle speed, m is the weight corresponding to the vehicle speed; y is the vehicle steering wheel angle, and n is the weight corresponding to the vehicle steering wheel angle. For example, g is 10, m is 0.5, and n is 60.

[0095] It can be seen that multiplying the vehicle speed and its corresponding weight and the steering wheel angle and its corresponding weight respectively, and then taking the sum of the two products as the final moving distance of the visual element, ensures that the moving distance of the visual element can comprehensively reflect the vehicle's driving speed and steering amplitude, providing passengers with more realistic visual feedback.

[0096] In another embodiment, when the vehicle is traveling in a straight line, the direction of the vehicle state change includes the direction of the vehicle acceleration; based on the direction of the vehicle state change in the vehicle operating state, the moving direction of the target visual element is determined, including: when the direction of the vehicle acceleration represents that the vehicle is accelerating, the element movement direction is determined to be a direction of moving downward along the longitudinal edge area; when the direction of the vehicle acceleration represents that the vehicle is decelerating, the element movement direction is determined to be a direction of moving upward along the longitudinal edge area.

[0097] In the specific implementation, when the vehicle is accelerating, the acceleration direction is forward, indicating that the vehicle speed is increasing, and the target visual element will move downward along the longitudinal edge area to simulate the change effect of human inertia when the vehicle is rushing forward. When the vehicle is decelerating, the acceleration direction is backward, indicating that the vehicle speed is decreasing, and the visual element will move upward along the longitudinal edge area to simulate the change effect of human inertia when the vehicle is decelerating.

[0098] The technical solution of this embodiment can control the moving direction of visual elements according to the acceleration direction of the vehicle, providing passengers with more realistic and delicate visual feedback, thereby helping passengers better perceive the acceleration and deceleration state of the vehicle, reducing motion sickness and improving riding comfort and safety.

[0099] In another embodiment, when the vehicle is turning, the direction of the vehicle state change includes the direction of the vehicle acceleration and the direction of the change of the vehicle steering wheel angle. The moving direction of the target visual element is determined according to the direction of the vehicle state change in the vehicle operating state, including: when the direction of the vehicle acceleration and the direction of the change of the vehicle steering wheel angle represent that the vehicle is turning left, the element movement direction is determined to be a direction of moving to the right along the lateral edge area; when the direction of the vehicle acceleration and the direction of the change of the vehicle steering wheel angle represent that the vehicle is turning right, the element movement direction is determined to be a direction of moving to the left along the lateral edge area.

[0100] In a specific implementation, when a vehicle turns, a lateral acceleration is generated. The direction of the lateral acceleration can be used to determine whether the vehicle is turning left or right. The direction of the change in the vehicle's steering wheel angle can be used to determine whether the vehicle is turning left or right. For example, when turning left, the steering wheel angle turns left, and when turning right, the steering wheel angle turns right. Combining the acceleration direction and the direction of the steering wheel angle change, it can be determined whether the vehicle is turning left or right.

[0101] When the vehicle is turning left, the element's moving direction is determined to be the direction moving to the right along the lateral edge area, which can express the centrifugal force feeling that the passengers are shifted to the right when the vehicle turns left; when the vehicle is turning right, the element's moving direction is determined to be the direction moving to the left along the lateral edge area, which can express the centrifugal force feeling that the passengers are shifted to the left when the vehicle turns right.

[0102] The technical solution of this embodiment uses the direction of change of vehicle acceleration and steering wheel angle to accurately control the moving direction of visual elements. The moving direction of visual elements can accurately correspond to the actual turning situation of the vehicle, allowing passengers to intuitively feel the dynamic state of the vehicle and reduce motion sickness caused by turning.

[0103] In order to facilitate the understanding of those skilled in the art, Figure 5 A schematic diagram of a visual element moving up and down is provided as an example. Figure 5 As shown, when the vehicle accelerates forward, the longitudinal halo slides downward, and the longitudinal movement distance is d1=a*tempZ. When the vehicle decelerates, the longitudinal halo can slide upward at a fixed speed, and the longitudinal movement distance is d1=a*tempZ.

[0104] In order to facilitate the understanding of those skilled in the art, Figure 6 A schematic diagram of a visual element moving left and right is provided as an example.

When the vehicle turns right, the lateral halo moves to the left, and the lateral movement distance is d2 = g*(m*x+n*y).
