[0035] The technical solutions in the present disclosure will be described clearly and completely below in conjunction with the accompanying drawings in the present disclosure.

[0036] In this disclosure, the word "exemplary" is used to mean an example, illustration, or description. Any embodiment or implementation described as an "exemplary" in this disclosure should not be interpreted as being more preferred or advantageous over other embodiments or implementations. Rather, the use of the word exemplary is intended to present concepts in a concrete way.

[0037] See also Figure 1 , which shows an example of a vehicle-mounted system 100 that can be applied to the technical solution of the present disclosure. In some examples, the vehicle equipped with the system 100 can be any type of vehicle, including but not limited to various types of cars, cross-border utility vehicles (car-based utility vehicles, CUV), sport utility vehicles (sport utility vehicles, SUV), trucks, recreation vehicles (recreation vehicles, RV) or other mobile machinery for transporting people or goods.

[0038] In many cases, the vehicle equipped with the system 100 may be a hybrid electric vehicle (HEV) powered by both an internal combustion engine and one or more electric motors, such as a series hybrid electric vehicle (SHEV), a plug-in hybrid electric vehicle (PHEV), and a power-split hybrid electric vehicle (PSHEV). As another possibility, the vehicle equipped with the system 100 may also be an electric vehicle (EV) using an electric motor as a power source, or other mobile machinery for transporting people or goods. In the subsequent content of this specification, the vehicle equipped with the vehicle-mounted system 100 is referred to as the vehicle, and all or part of the power of the vehicle comes from electricity, that is, the electric motor.

[0039] like Figure 1As shown, the vehicle-mounted system 100 includes: a navigation subsystem 110, an environmental detection device group 120 for acquiring the vehicle's environment during driving, a vehicle driving status detection device group 130, an electric power drive subsystem 140, a data processing unit 150, a display control unit 160 and a display unit 170. The above-mentioned components or device groups are coupled together through a communication bus 12. In some examples, the communication bus 12 is used for connection and communication between the above-mentioned components or device groups, such as a controller area network (CAN), a local interconnect network (LIN), a FlexRay bus, a media oriented systems transport (MOST) bus, an in-vehicle Ethernet, etc. It should be noted that Figure 1 Only a portion of the in-vehicle system 100 is shown, not all of the components of the in-vehicle system 100 .

[0040] exist Figure 1 In the navigation subsystem 110, a positioning device 111 and a map information storage device 112 are included. The positioning device 111 can locate the position of the vehicle based on the global positioning system (GPS), China's Beidou system, Russia's GLONASS system, Europe's Galileo system, Japan's Quasi-Zenith Satellite System (QZSS), India's Indian Regional Navigation Satellite System (IRNSS) and other positioning systems to obtain the position information of the vehicle. The map information storage device 112 stores map information, and can obtain a navigation path leading to the destination according to the position information obtained from the positioning device 111, and display the position information and the navigation path in the map application.

[0041] exist Figure 1 In the embodiment, the environment detection device group 120 may include an on-vehicle communication device 121, a radar 122, a laser rangefinder 123, and a camera 124. These devices can acquire environmental information representing the surrounding environment of the vehicle.

[0042] The vehicle-mounted communication device 121 can communicate wirelessly with one or more devices directly or via a communication network. These devices that can communicate with the vehicle-mounted communication device 121 can be other vehicles, roadside machines or roadside platforms, or mobile terminal devices used by occupants of the vehicle.

[0043] In some examples, the vehicle communication device 121 can communicate using various wireless communication systems, and can also communicate with a wireless local area network (WLAN) using WiFi. In some embodiments, the vehicle communication device 121 can also communicate directly with the device using an infrared link, Bluetooth, or ZigBee. In some examples, the vehicle communication device 121 can also communicate with the device using other wireless protocols.

[0044] Radar 122 is used to sense objects in the surrounding environment of the vehicle, and can also be used to sense the speed and / or direction of these objects. In some examples, radar 122 can rely on electromagnetic waves or lasers as a medium to detect objects based on time of flight (TOF) or phase-shift methods, and detect the position of the detected object, the distance to the detected object, and the relative speed. In some examples, in order to be able to detect objects located in front of, behind, or to the side of the vehicle, radar 122 can be configured at an appropriate position outside the vehicle.

[0045] The laser rangefinder 123 may utilize laser light to sense objects in the environment in which the host vehicle is located. In some embodiments, the laser rangefinder 123 may include one or more laser sources, a laser scanner, and one or more detectors, among other system components.

[0046] The camera 124 can be used to capture multiple images of the surrounding environment of the vehicle. The camera 124 can be a static camera or a video camera. In some examples, in order to obtain the external image of the vehicle, the camera 124 can be located at an appropriate position outside the vehicle. For example, in order to obtain the image in front of the vehicle, the camera 124 can be configured in the interior of the vehicle close to the front windshield. Alternatively, the camera 124 can be configured around the front bumper or radiator grille. In some examples, in order to obtain the image behind the vehicle, the camera 124 can be configured in the interior of the vehicle close to the rear window glass. Alternatively, the camera 124 can be configured around the rear bumper, trunk or tailgate. In some examples, in order to obtain the image of the side of the vehicle, the camera 124 can be configured in the interior of the vehicle close to at least one of the side windows. Alternatively, the camera 124 can be configured around the side mirrors, fenders or doors.

[0047] exist Figure 1In the embodiment, the vehicle driving state detection device group 130 may include: a steering angle sensor 131 for detecting the steering angle of the vehicle, a vehicle speed sensor 132 for detecting the driving speed of the vehicle, and an acceleration sensor 133 for detecting the acceleration applied to the vehicle. In some examples, as shown in the dotted box, an inertial sensor 134 for detecting the position and orientation change of the vehicle based on inertial acceleration may also be included. The inertial sensor 134 may be a combination of the acceleration sensor 133 and a gyroscope in a specific implementation process.

[0048] exist Figure 1 In the embodiment, the electric power drive subsystem 140 may include: an electric motor 141 for providing power for the driving of the vehicle, an energy storage unit 142 (such as a rechargeable battery) that provides power to the electric motor 141, a charging device 143 that can charge the energy storage unit 142, and a power monitoring device 144 that can collect relevant data on the operating status of the electric motor 141, the power status of the energy storage unit 142, and the charging status of the charging device 143.

[0049] The vehicle can receive the transmitted electric energy from the outside through the charging device 143 and store the electric energy in the energy storage unit 142 to complete the process of charging the energy storage unit 142. In some examples, the charging process usually requires the vehicle to travel to a fixed location where a charging device (such as a charging pile, a charging station or a similar device) is set, and the charging device is connected to the charging device to transmit the electric energy in the charging device to the vehicle through the charging device. Such a charging process connects the vehicle to a stationary, fixed-position charging station or a similar device and the vehicle cannot move during the charging time.

[0050] In some examples, in order to improve the flexibility of the charging process, the energy storage unit 142 of the vehicle in motion can be charged by wireless charging, so that the vehicle can be charged while driving. Figure 2As shown, a transmitting end 21 for providing electric energy may be laid under the road surface 2 on which the vehicle 1 is traveling, and the charging device 143 of the vehicle 1 may specifically be a receiving end 22 for receiving electric energy. Taking the wireless charging method of inductive power transmission as an example, the transmitting end 21 may be a coil connected to the power grid and laid under the driving road surface to convert the electric energy provided by the power grid into an alternating magnetic field, and the receiving end 22 may be a coil arranged on the chassis of the vehicle 1, and current is induced by receiving the alternating magnetic field generated by the transmitting end 21, thereby charging the energy storage unit 142. In addition, taking the resonant magnetic field as an example, the transmitting end 21 may be a resonant element connected to the power grid and laid under the road surface to convert electric energy into a resonant magnetic field, and the receiving end 22 may be a resonant element arranged on the chassis of the vehicle 1, and current is induced by receiving the resonant magnetic field generated by the transmitting end 21, thereby charging the energy storage unit 142. It can be understood that when multiple transmitting terminals 21 are laid under the driving road surface along the road direction 3 shown by the arrow, the vehicle 1 can be wirelessly charged with the transmitting terminals 21 passing by through the above example while driving on the road along the road direction. Of course, the above inductive power transmission and resonant magnetic field transmission are only used to exemplarily illustrate the dynamic charging state of the vehicle charging while driving. Other power transmission methods applicable to the dynamic charging state are also applicable to the present disclosure and will not be repeated here.

[0051] exist Figure 1 In the embodiment, the data processing unit 150 can be implemented as a computing system having a memory, a processor, an input / output interface, and a bus connected to these buses. In some examples, the data processing unit 150 causes the processor to execute multiple commands through program instructions stored in the memory to process the data obtained by the navigation subsystem 110, the environment detection device group 120, the vehicle driving state detection device group 130, and the electric power drive subsystem 140. In some examples, the data processing unit 150 can also partially or completely control the driving of the vehicle based on the processed data.

[0052] exist Figure 1 As shown in the dotted box, the display control unit 160 and the display unit 170 can serve as the main body of the head-up display (HUD) device 170. The display control unit 160 can process the received data processed by the data processing unit 150, or after receiving the data obtained by the navigation subsystem 110, the environment detection device group 120 and the vehicle driving state detection device group 130, to obtain display information to be displayed, and project the display information onto the windshield of the vehicle through the display unit 170 for display.

[0053] Combination Figure 3 An exemplary cross-sectional view of the vehicle shown and Figure 4The exemplary perspective view from the driver's seat of the present vehicle is shown, and the present vehicle includes a windshield 204 located at the front of the vehicle. The driver and passengers in the passenger cabin 208 of the present vehicle can see the front of the present vehicle through the windshield 204.

[0054] exist Figure 3 as well as Figure 4 In the embodiment of the present invention, the windshield 204 is visually located above the vehicle dashboard 206. The driver can turn the steering wheel 210 in the passenger cabin 208 to steer the vehicle, such as changing lanes, merging and parking the vehicle. In some embodiments, the steering wheel 210 can be retracted or omitted.

[0055] In the present disclosure, taking a panoramic head-up display (PHUD) device as an example, the display unit 170 in the head-up display device 180 is generally arranged on the upper side of the instrument panel 206 below the windshield 204. The display unit 170 is controlled by the display control unit 160 so as to output the image desired to be displayed for perception by the vehicle occupants, and may include a display unit 171 for presenting display information. In addition, a display screen 172 is arranged in front of the windshield 204. The display screen 172 extends on most of the windshield 204 and in front of the lower area connected to the lower edge of the windshield 204 and provides a strip-shaped display area, which is used to reflect the image displayed by the display unit 171. In some examples, the display screen 172 may be directly mounted on the windshield 204 or arranged in front of the inner side of the windshield at a spacing between 0 and 10 cm.

[0056] Screen 172 is reflective, ie has a reflective surface, at least on the side facing away from windshield 204 , so that the display image displayed on display unit 171 can be perceived on the reflective surface with minimal light intensity loss and without perceptible double images.

[0057] The display unit 171 is oriented relative to the display area of ​​the windshield 204 so that the image displayed on the display unit 171 of the display unit 170 is reflected by projection onto the reflective surface of the display screen 172, and the reflection can be perceived by the vehicle occupant in the eye area B. Thus, the display unit 170 or its display unit 171 is preferably oriented substantially parallel to the longitudinal and transverse axes of the vehicle or deviates from the longitudinal and transverse axes of the vehicle by an angle of no more than 0° to 30°. In some examples, the image can be projected by the display unit 171 using a micromirror array or a light guide plate.

[0058] The display unit 170 is installed in the recessed portion 6 of the instrument panel 206, so that the driver cannot directly see the display unit 171 of the display unit 170 and avoids the driver being dazzled by direct light from the display unit 171 entering the eye area B. In addition, the display unit 171 of the display unit 170 is oriented so that the displayed display image is reflected on the reflective surface of the display screen 172 and can be perceived by the driver in the eye area B as a reflected image R on the display screen 172.

[0059] The display screen 172 can be arranged directly on the lower area of ​​the windshield 204 over most of the width of the windshield 204. This lower area of ​​the windshield 204 usually has a black printed area 51 and is therefore opaque. The black printed area usually has a height of between 5 and 30 cm from the lower edge of the windshield 204.

[0060] The upper side of the display screen 172 may be substantially flush with the upper side of the black printed area of ​​the windshield 204 or vertically below the black printed area. In particular, the upper and lower edges of the display screen 172 may be curved to correspondingly mimic the curvature of the windshield 204 in the vehicle width direction.

[0061] Based on the above schematic description of the PHUD architecture, the PHUD can provide a wider display area, that is, it can basically cover the width of the black printed area 51 at the bottom of the windshield 204, that is, the driver's field of view extending from the left A-pillar of the vehicle to the right A-pillar of the vehicle. In such a wide display area, more display content can be provided compared to the current HUD.

[0062] In the current related solutions, many solutions are provided for using HUD to display the charging status of the vehicle when it is parked at a charging station or charging pile for charging, but there is no display control solution for the dynamic charging status when the vehicle is wirelessly charged while driving. The present disclosure hopes to display the charging status of the vehicle during the dynamic charging process in combination with PHUD, so that the driver can perceive and understand the charging status of the dynamic charging process more intuitively.

[0063] Based on this, see Figure 5 , which shows a display control method provided by the present disclosure, which can be applied to the display control unit 160 of a panoramic head-up display (PHUD, Panorama-Head-up-Display) device, and the method may include steps S501 to S503.

[0064] In step S501, when the vehicle is in a dynamic charging state, a fixed element representing the current power level of the vehicle is controlled to be displayed in the center of a target area of ​​a display screen of the PHUD device.

[0065] In the present disclosure, when the vehicle is traveling in Figure 2 When a road for providing electric energy is paved under the road surface shown, the power monitoring device 144 monitors whether the charging device 143 receives the electric energy transmitted by the transmitting end 21 through the alternating magnetic field or the resonant magnetic field. When the power monitoring device 144 monitors that the charging device 143 receives the electric energy transmitted by the alternating magnetic field or the resonant magnetic field, it can be determined that the vehicle is in a dynamic charging state of driving and charging at the same time, and in the present disclosure, the charging process in this dynamic charging state is referred to as a dynamic charging process.

[0066] In the present disclosure, the target area may include all or part of the display screen 172. Figure 3 and Figure 4 Taking the width of the display screen 172 of the PHUD device shown as an example, the width of the display screen 172 is much greater than the height of the display screen 172, and the overall appearance is as follows: Figure 6 Taking the target area as the entire display screen 172 as an example, when it is determined that the vehicle is in a dynamic charging state, and the entire display screen 172 is used to prompt or perceive the charging state of the dynamic charging process to the driver, as shown in FIG. Figure 6 As shown, the display control unit 160 can control a fixed element 61 (e.g., a fixed circular bubble) to be displayed in the central area of ​​the display screen 172 of the PHUD device, and the fixed element can represent the energy storage unit 142 of the vehicle, such as the power of the battery. In the present disclosure, the power is expressed as a percentage. It can be understood that as the dynamic charging proceeds, the power (i.e., the percentage value) will gradually increase until it reaches the maximum power that the battery can store (i.e., the percentage value is 100%).

[0067] In step S502, the dynamic charging parameters of the vehicle in the dynamic charging state are obtained.

[0068] In the present disclosure, when the vehicle is in a dynamic charging state, the power monitoring device 144 can also monitor and obtain the state parameters of the charging device 143 during the charging process, that is, the dynamic charging parameters. Exemplarily, the dynamic charging parameters may include the instantaneous power of the charging device 143 charging the energy storage unit 142 during the dynamic charging process, the receiving power of the electric energy received by the charging device 143 from the transmitting end 21 under the road surface, and the transmission power of the electric energy transmitted from the transmitting end 21 under the road surface to the charging device 143. In addition, other power parameters that can characterize the dynamic charging process can be considered as dynamic charging parameters, which will not be elaborated in the present disclosure.

[0069] In step S503, the playing parameters of the moving animation of the moving element moving from the edge of the target area to the fixed element are controlled according to the dynamic charging parameters, so as to play the moving animation on the display screen of the PHUD device.

[0070] In the present disclosure, Figure 6 In the example shown, when the target area is the entire display screen 172, the display control unit 160 plays a moving animation of the moving element 62 moving from the edge of the display screen 172 to the fixed element 61 on the display screen 172 of the PHUD device according to the dynamic charging parameters. Specifically, according to the dynamic charging parameters obtained in step S502, the display control unit 160 can correspond the playback parameters such as the size and number of the moving elements 62, the playback speed of the moving animation (i.e., the movement speed of the moving elements) with these dynamic charging parameters, so as to play the moving animation by controlling the corresponding playback parameters so that the driver can intuitively understand and grasp the charging process under the dynamic charging state by watching the moving animation. In the present disclosure, Figure 6 As shown in the dotted box, the moving element 62 can be a small-sized bubble or a group of small-sized bubbles that are smaller than the fixed element 61 (fixed bubble). By playing the moving animation of the small-sized bubble or the group of small-sized bubbles moving from the edge of the display screen 172 to the fixed bubble in the direction indicated by the arrow, and as the moving animation is played repeatedly, the small-sized bubble or the group of small-sized bubbles will be displayed as being absorbed into the fixed bubble, and the current power represented by the fixed bubble will gradually increase as the dynamic charging process proceeds, so that the driver can intuitively know the dynamic charging process that is currently in the dynamic charging state.

[0071] pass Figure 5 The technical solution shown in the present disclosure is combined with PHUD to display the charging status of the vehicle during the dynamic charging process by playing a moving animation in which a moving element moves from the edge of the display screen to a fixed element displayed in the center area of ​​the display screen, which can allow the driver to perceive and understand the charging status of the dynamic charging process more intuitively.

[0072] based on Figure 5 In some possible implementations of the technical solution shown, the control for displaying a fixed element representing the current power of the vehicle at the center of a target area of ​​a display screen of a PHUD device includes:

[0073] Obtaining a quantity representing the current power of the vehicle;

[0074] The display parameters of the filling element are controlled according to the characterization amount, and the filling element is displayed in a filling manner within the fixed element at the center of the target area according to the display parameters.

[0075] For the above implementation, specifically, taking a fixed bubble as an example, the filling element may be an image element that can be filled into the fixed bubble, such as a flowing liquid, etc. The current power of the vehicle can also be represented by different characterization quantities, for example, the current remaining power value of the vehicle (in kwh), the percentage of the current power reaching the maximum power that the battery can store (expressed as a percentage), and the remaining mileage of the vehicle that can be traveled calculated according to the current power provided to the electric motor (in km). Taking percentage as an example, if Figure 7 As shown, the present disclosure fills the flowing liquid 71 into the fixed bubble 61, and the filled area is the percentage of the current power reaching the maximum power that the battery can store, so that the current power of the vehicle can be represented in the fixed element. In some examples, the specific value of the representation of the current power of the vehicle can also be displayed in the fixed element, for example Figure 8 As shown, when the current power reaches 60% of the maximum power that the battery can store, "60%" is displayed in a fixed bubble.

[0076] Based on the above implementation, in order to enable the driver to understand the current power level more intuitively, color can also be used for reminder. In some examples, the method further includes:

[0077] When the percentage of the current power of the vehicle reaching the maximum power that can be stored in the battery is less than or equal to a first threshold, controlling the colors of the fixed element, the filling element and the moving element to be displayed as a first color;

[0078] When the percentage of the current power of the vehicle reaching the maximum power that can be stored in the battery is greater than the first threshold and less than or equal to the second threshold, controlling the colors of the fixed element, the filling element and the moving element to be displayed as the second color;

[0079] When the percentage of the current power of the vehicle reaching the maximum power that can be stored in the battery is greater than a second threshold, the colors of the fixed element, the filling element and the moving element are controlled to be displayed as a third color.

[0080] In the above example, the first threshold is less than the second threshold. Exemplarily, the present disclosure sets the first threshold to 10% and the second threshold to 30%. Fig. 9 As shown, when the current power of the vehicle reaches a percentage of the maximum power that the battery can store that is less than 10%, it means that the current power is too low to support the vehicle to travel a long distance, and the vehicle needs high-power charging with high urgency, so the warning first color, such as Fig. 9The red color shown in the middle left picture reminds the driver to avoid any driving operation that consumes a lot of power during driving, and to drive to the nearest charging pile or charging station with higher charging power as soon as possible for charging. When the current power of the vehicle reaches a percentage greater than 10% and less than or equal to 30% of the maximum power that the battery can store, it means that although the current power is low, it can still support the vehicle to travel a long distance. Therefore, a second color with less urgency is used, such as Fig. 9 The yellow color shown in the middle image of the figure reminds the driver to pay attention to reducing the power consumption of driving operations and to find a charging pile or charging station within the longer distance for charging. When the current power of the vehicle reaches a percentage greater than 30% of the maximum power that the battery can store, it means that the current power is sufficient. As the dynamic charging process proceeds, there is no need to pay attention to the power consumption of driving operations, nor is there any need to find a charging pile or charging station with higher charging efficiency for charging. Therefore, if Fig. 9 As shown in the middle right picture, it is displayed using a third color that cannot cause a sense of urgency to human perception, such as green.

[0081] based on Figure 5 The technical solution shown in the figure needs to control the display of mobile elements in addition to the display control of fixed elements. In some possible implementations, when the dynamic charging parameter includes the instantaneous power of the charging device of the vehicle charging the energy storage unit during the dynamic charging process, the playback parameters of the moving animation of controlling the moving element to move from the edge of the target area to the fixed element according to the dynamic charging parameter include:

[0082] Determine the display size of the mobile element according to the upper and lower limits of the size of the mobile element and the instantaneous power;

[0083] The display size of the moving element is used as a play parameter for controlling the display of the moving animation.

[0084] For the above implementation, in the present disclosure, the size of the mobile element (such as a moving bubble or a bubble group) corresponds to the instantaneous power during charging, which can be represented by a power value or a current value, and the larger the instantaneous power, the larger the mobile element. In some examples, the upper and lower limits of the size of the mobile element are set to be S max and S min , understandably, S max During the charging process, the instantaneous power is also within the upper and lower limits, which are respectively marked as P max and P min Based on instantaneous powerP As well as the above two upper and lower limit ranges, when the target area is the entire display screen, the size of the moving element is obtained according to the following formula :

[0085] .

[0086] It should be noted that in some examples, when the target area is a portion of the display screen, the size of the mobile element can be based on Reduce the size of the target area according to the proportion of the display screen. Set the proportion of the target area to m, and move the size of the element when the target area is part of the display screen. It can be obtained by the following formula:

[0087] .

[0088] Understandably, Substitute the calculation formula into ,It can still be seen that, no matter the target area is the whole or part of the display screen, the display size of the moving element is still only related to the upper and lower limits of the size of the moving element and the instantaneous power.

[0089] Based on the above implementation, in addition to the size of the moving element, the instantaneous power can also be represented by the number of moving elements. In some possible implementations, when the dynamic charging parameter is the instantaneous power of the charging device of the vehicle charging the energy storage unit during the dynamic charging process, the playback parameters of the moving animation of controlling the moving element to move from the edge of the target area to the fixed element according to the dynamic charging parameter include:

[0090] Obtaining a display scale constant according to display parameters of the target area of ​​the display screen;

[0091] Determining the number of moving elements in the moving animation based on the display scale constant and the instantaneous power;

[0092] The number of the moving elements is used as a playback parameter for controlling the display of the moving animation.

[0093] For the above implementation, in the present disclosure, the display proportional constant is used to control the number of moving elements to present a better effect on the display screen of the PHUD, which is usually related to the width, length and refresh rate of the target area in the display screen. Specifically, taking the moving bubble as an example, the proportional constant Proportional to the width of the target area, ensuring that the number of moving bubbles in areas of different widths remains at an appropriate visual density; proportional constant Inversely proportional to the height H of the target area, ensuring a reasonable vertical distribution of the moving bubbles; proportional constant With refresh rate The association can affect the generation and smoothness of the moving bubbles. A higher refresh rate allows more moving bubbles to move smoothly to optimize the dynamic display effect. In some examples, taking the target area as the entire display screen as an example, the width of the target area is the width of the display screen. L , the height of the target area is the height of the display screen H , the refresh rate of the display is Based on the above display parameters, the display proportional constant can be obtained by the following formula :

[0094]

[0095] in, and It is an adjustment factor used to adjust according to specific visual effect requirements. Indicates the adjustment coefficient of the effect of aspect ratio on the number of bubbles; Indicates the adjustment coefficient of the effect of refresh rate on the number of bubbles.

[0096] In order to obtain the display proportional constant After that, the number of moving elements can be calculated according to the following formula in combination with the instantaneous power P: :

[0097] .

[0098] In some examples, when the target area is a portion of a display screen, the number of moving elements can be based on Zoom out according to the ratio of the target area to the display screen. Set the ratio of the target area to the display screen to n, and the number of elements to move when the target area is part of the display screen It can be obtained by the following formula:

[0099] .

[0100] Understandably, Substitute the calculation formula into ,It can be seen that no matter the target area is the whole or part of the display screen, the number of ,moving elements is still only related to the display scale constant and ,the instantaneous power.

[0101] Based on the above two implementation methods, taking moving bubbles as an example, when the number of moving bubbles increases and the size of the moving bubbles increases, the driver can perceive that the charging power is larger while watching the moving animation, so that the driver can intuitively perceive the charging power.

[0102] based on Figure 5In the technical solution shown, when the dynamic charging parameters include the receiving power of the electric energy received by the charging device of the vehicle from the transmitting end under the road surface during the dynamic charging process and the transmission power of the electric energy transmitted from the transmitting end under the road surface to the charging device, the playback parameters of the moving animation of controlling the moving element to move from the edge of the target area to the fixed element according to the dynamic charging parameters include:

[0103] Obtain charging efficiency based on received power and transmitted power;

[0104] Obtain the moving speed of the moving element according to the charging efficiency and the base speed of the moving element;

[0105] The display size of the moving element is used as a play parameter for controlling the display of the moving animation.

[0106] For the above implementation, during the dynamic charging process, the charging efficiency is the ratio of the received power P1 to the transmitted power P2, that is The reference speed V0 of the mobile element can be the mobile speed set when the charging efficiency is 100%. Based on the above charging efficiency and reference speed, the mobile speed of the mobile element can be obtained. It can be seen that when the charging efficiency is higher, the moving speed of the moving element is faster. When watching the moving animation, the driver can intuitively perceive the charging efficiency through the moving speed of the moving element.

[0107] In some examples, taking moving bubbles as an example, in order to ensure that the visual effect is consistent and intuitive on different vehicles and display sizes, the speed of the moving bubbles is associated with the width of the target area, so that the movement speed of the moving bubbles can not only reflect the efficiency of wireless charging, but also show a natural and easy-to-read dynamic effect in the target area. Taking the target area as the entire display screen as an example, the width of the display screen is set to L (unit: pixel), and the moving bubble needs to move from one end of the screen to a fixed element (i.e., the center of the display screen) within a certain time T under the high-efficiency charging (100% efficiency) state, then the reference speed V0 can be defined as:

[0108]

[0109] In the specific implementation process, the time T can be optimized according to the user experience and display effect, usually between a few seconds. ), the dynamic bubble speed is the reference speed V0. When the charging efficiency changes, the moving speed V1 of the moving bubble is proportional to the charging efficiency, that is:

[0110] .

[0111] In the specific implementation process, it can also be optimized according to the vehicle type, the display screen size of the PHUD and the user preference. For a wider display screen, the reference time T can be appropriately shortened to avoid the bubbles moving too slowly.

[0112] In some examples, when the target area is part of a display screen, in addition to reducing V1 according to the ratio of the target area to the display screen according to the aforementioned implementation method, since the width of the target area occupies fewer pixels at this time, the speed of the moving bubble can also be set to a fixed constant value, which can be determined based on actual conditions.

[0113] In addition to the above implementations and examples, in some examples, the remaining charging time can also be estimated based on the current power and dynamic charging parameters, and the remaining charging time can be displayed in the fixed element. Specifically, the current power representation is set to the remaining mileage, the remaining mileage is 356km, and the remaining charging time is 21 minutes. Fig.10 As shown, based on the above example, "356 km" and "21 min" can be displayed in the fixed bubble.

[0114] It should be noted that when the target area is part of the display screen, the size of the fixed element may not be sufficient to display the specific value. Based on this, in some examples, the method further includes: displaying the specific value of the current power quantity of the vehicle and / or the remaining charging time in an area outside the moving animation. Specifically, still taking the remaining mileage of 356km and the remaining charging time of 21 minutes as an example, Fig.11 As shown, "356km" and "21min" are not displayed in the fixed bubble, nor in the playback area of ​​the moving animation shown in the dotted box, but are displayed outside the target area shown in the dotted box.
