[0037] In order to make the objectives, technical solutions, and advantages of the present disclosure clearer, the following will describe the example embodiments according to the present disclosure in detail with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, and not all embodiments of the present disclosure. It should be understood that the present disclosure is not limited by the example embodiments described herein.

[0038] In the present disclosure, the word “example” is used to mean serving as an example, instance, or illustration. Any implementation or implementation described as “example” in the present disclosure should not be interpreted as being preferred or advantageous over other implementations. Rather, the word “example” is used to present concepts in a concrete fashion.

[0039] Referring to FIG. 1, an example of an in-vehicle system 100 applicable to the technical solutions of the present disclosure is shown. In some examples, the vehicle carrying the system 100 can be any type of vehicle, including but not limited to various types of cars, car-based utility vehicles (CUVs), sport utility vehicles (SUVs), trucks, recreation vehicles (RVs), or other mobile machines for transporting people or goods.

[0040] In many cases, the vehicle carrying the system 100 can be a hybrid 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), a power-split hybrid electric vehicle (PSHEV). As another possibility, the vehicle carrying the system 100 can also be an electric vehicle (EV) using an electric motor as a power source, or other mobile machines for transporting people or goods. In the subsequent content of the present specification, the vehicle carrying the in-vehicle system 100 is referred to as the present vehicle, and all or part of the power of the present vehicle is derived from electricity, i.e., an electric motor.

[0041] As shown in FIG. 1, the in-vehicle system 100 includes a navigation subsystem 110, a group of environment detection devices 120 that acquire an environment in which a vehicle is located during travel of the vehicle, a group of vehicle travel state detection devices 130, an electric power drive subsystem 140, a data processing section 150, a display control section 160, and a display section 170. The above-described components or device groups are coupled together through a communication bus 12. In some examples, the communication bus 12 is used for connection communication between the above-described 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, and the like. Note that FIG. 1 shows only a part of the in-vehicle system 100, and does not show all components of the in-vehicle system 100.

[0042] In FIG. 1, the navigation subsystem 110 includes a positioning device 111 and a map information storage device 112. The positioning device 111 is capable of positioning a position of the host vehicle based on a global positioning system (GPS), a Chinese Beidou system, a Russian GLONASS system, a European Galileo system, a Japanese quasi-zenith satellite system (QZSS), an Indian regional navigation satellite system (IRNSS), and the like, and acquires position information of the host vehicle. The map information storage device 112 stores map information, and is capable of acquiring a navigation route to a destination based on the position information acquired from the positioning device 111, and displaying the position information and the navigation route in a map application.

[0043] In FIG. 1, the group of environment detection devices 120 can include an in-vehicle communication device 121, a radar 122, a laser range finder 123, and a camera 124. These devices are capable of acquiring environment information that represents a surrounding environment of the host vehicle.

[0044] The in-vehicle communication device 121 can wirelessly communicate with one or more devices directly or via a communication network. The devices that can communicate with the in-vehicle communication device 121 can be other vehicles, a road side unit or a roadside station, a mobile terminal device used by an occupant of the host vehicle, and the like.

[0045] In some examples, the in-vehicle communication device 121 can communicate using various wireless communication systems, and can also communicate with wireless local area networks (WLANs) using WiFi. In some embodiments, the in-vehicle communication device 121 can also communicate directly with devices using infrared links, Bluetooth, or ZigBee. In some examples, the in-vehicle communication device 121 can also communicate with devices using other wireless protocols.

[0046] The radar 122 is used to sense objects within the surrounding environment of the host vehicle, and can also be used to sense the speed and / or direction of travel of the objects. In some examples, the radar 122 can rely on electromagnetic waves or laser light as a medium, and can detect objects based on a time of flight (TOF) method or a phase shift method, and can detect the position, distance, and relative speed of the detected objects. In some examples, in order to be able to detect objects located in front of, behind, or to the side of the host vehicle, the radar 122 can be configured at an appropriate position on the exterior of the host vehicle.

[0047] The laser range finder 123 can use laser light to sense objects in the environment in which the host vehicle is located. In some embodiments, the laser range finder 123 can include one or more laser light sources, a laser light scanner, and one or more detectors, as well as other system components.

[0048] The camera 124 can be used to capture multiple images of the surrounding environment of the host vehicle. The camera 124 can be a still camera or a video camera. In some examples, in order to acquire images of the exterior of the host vehicle, the camera 124 can be located at an appropriate position on the exterior of the host vehicle. For example, in order to acquire images of the front of the host vehicle, the camera 124 can be configured in close proximity to the front window on the interior of the host vehicle. Alternatively, the camera 124 can be configured in close proximity to the front bumper or the perimeter of the radiator grille. In some examples, in order to acquire images of the rear of the host vehicle, the camera 124 can be configured in close proximity to the rear window on the interior of the host vehicle. Alternatively, the camera 124 can be configured in close proximity to the rear bumper, the trunk, or the perimeter of the tailgate. In some examples, in order to acquire images of the side of the host vehicle, the camera 124 can be configured in close proximity to at least one of the side windows on the interior of the host vehicle. Alternatively, the camera 124 can be configured in close proximity to the side mirrors, the fenders, or the doors.

[0049] In FIG. 1, the vehicle driving state detection device group 130 can include a steering angle sensor 131 that detects a steering angle of the host vehicle, a vehicle speed sensor 132 that detects a driving speed of the host vehicle, and an acceleration sensor 133 that detects an acceleration applied to the host vehicle. In some examples, as shown by the dashed-line box, an inertial sensor 134 that detects a change in position and orientation of the host vehicle based on inertial acceleration can also be included, which in a particular implementation can be a combination of the acceleration sensor 133 and a gyroscope.

[0050] In FIG. 1, the electric power drive subsystem 140 can include an electric motor 141 for providing power for driving of the host vehicle, an energy storage unit 142 (such as a rechargeable battery) for providing power to the electric motor 141, a charging device 143 capable of charging the energy storage unit 142, and a power monitoring device 144 capable of collecting relevant data on an operating state of the electric motor 141, an electric energy state of the energy storage unit 142, and a charging state of the charging device 143.

[0051] The host vehicle can receive transmitted electric energy from the outside world through the charging device 143 and store the electric energy into the energy storage unit 142 to complete the process of charging the energy storage unit 142. In some examples, the charging process typically requires the host vehicle to drive to a fixed location where a charging device (such as a charging post, a charging station, or similar device) is provided, connect the charging device with the charging device to transmit electric energy in the charging device to the host vehicle through the charging device. Such a charging process connects the host vehicle to a stationary, position-fixed charging station or similar device and the host vehicle cannot move during the charging time.

[0052] In some examples, in order to improve the flexibility of the charging process, the energy storage unit 142 of the host vehicle in the driving state can be charged in a wireless charging manner, so that the host vehicle can realize charging while driving. In some examples, in combination with FIG. 2, the road surface 2 on which the host vehicle 1 drives can be paved with a sending end 21 for providing electric energy, and the charging device 143 of the host vehicle 1 can be a receiving end 22 for receiving electric energy. For example, in an inductive power transmission wireless charging manner, the sending end 21 can be a coil connected to the power grid and paved 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 can be a coil arranged on the chassis of the host vehicle 1, to induce an electric current by receiving the alternating magnetic field generated by the sending end 21, thereby charging the energy storage unit 142. In addition, for example, in a resonant magnetic field, the sending end 21 can be a resonant element connected to the power grid and paved under the road surface, to convert the electric energy into a resonant magnetic field, and the receiving end 22 can be a resonant element arranged on the chassis of the host vehicle 1, to induce an electric current by receiving the resonant magnetic field generated by the sending end 21, thereby charging the energy storage unit 142. It should be understood by those skilled in the art that when a plurality of sending ends 21 are paved under the driving road surface along the road direction indicated by the arrow, the host vehicle 1 can be wirelessly charged with the sending ends 21 passed through during driving on the road surface in the road direction by the above examples. 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 means suitable for the dynamic charging state are also applicable to the present disclosure, and will not be described here.

[0053] In FIG. 1, the data processing part 150 can be implemented as a computing system having a memory, a processor, an input / output interface, and a bus connecting these. In some examples, the data processing part 150 causes the processor to execute a plurality of commands by 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 driving subsystem 140. In some examples, the data processing part 150 can also control the driving of the host vehicle based on the processed data in part or in whole.

[0054] In FIG. 1, as shown by the dashed box, the display control section 160 and the display section 170 can be the main body of a head-up display (HUD) device 170. The display control section 160 can process the data received after the data processing section 150 processes the data, or after the data received from the navigation subsystem 110, the environmental detection device group 120, and the vehicle running state detection device group 130, to obtain display information to be displayed, and project the display information to the windshield of the host vehicle for display by the display section 170.

[0055] In conjunction with the exemplary cross-sectional view of the host vehicle shown in FIG. 3 and the exemplary perspective view from the driver's seat of the host vehicle shown in FIG. 4, the host vehicle includes a windshield 204 located at the front of the vehicle. The driver and passengers in the passenger cabin 208 of the host vehicle can see the front of the host vehicle through the windshield 204.

[0056] In FIGS. 3 and 4, the windshield 204 is visually located above the vehicle dashboard 206. The driver can turn the steering wheel 210 within the passenger cabin 208 to steer the vehicle, for example, to change lanes, merge, and park the vehicle. In some embodiments, the steering wheel 210 can be stowed or omitted.

[0057] In the present disclosure, the display section 170 in the head-up display device 180 is typically provided on the upper side of the dashboard 206 below the windshield 204, which is controlled by the display control section 160, for outputting the image to be displayed for the perception of the vehicle occupants, taking the example of a panorama-head-up-display (PHUD) device. The display section 170 can include a display unit 171 for presenting the display information. In addition, a display screen 172 is provided in front of the windshield 204. The display screen 172 is on most of the windshield 204 and extends in front of the lower area connected to the lower edge of the windshield 204 and provides a strip-shaped display area for reflecting the image displayed by the display unit 171. In some examples, the display screen 172 can be mounted directly on the windshield 204 or provided in front of the windshield inside with a spacing of between 0 and 10 cm.

[0058] The display screen 172 has a reflective configuration on at least the side facing away from the windshield 204, i.e., configured with a reflective surface, so that the image displayed on the display unit 171 can be perceived on the reflective surface with as little loss of light intensity and as little perceivable ghosting as possible.

[0059] The display unit 171 is oriented relative to the display area of the windshield 204 such that an image displayed on the display unit 171 of the display section 170 is reflected by being projected onto the reflective surface of the display screen 172 and the reflection can be perceived by the vehicle occupant in the eye region B. Thereby, the orientation of the display section 170 or its display unit 171 is preferably substantially parallel to the vehicle longitudinal and transverse axes or deviates from the vehicle longitudinal and transverse axes by an angle of not more than 0° to 30°. In some examples, the projection of the image can be realized by the display unit 171 using a micromirror array or a light guide plate.

[0060] The display section 170 is mounted in a recess 6 of the dashboard 206 such that the display unit 171 of the display section 170 cannot be directly seen by the driver and the driver is protected from glare by direct light from the display unit 171 entering the eye region B. Furthermore, the display unit 171 of the display section 170 is oriented such 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 region B as a reflected image R on the display screen 172.

[0061] The display screen 172 can be arranged directly on a lower region of the windshield 204 over a substantial part of the width of the windshield 204. This lower region of the windshield 204 usually has a black printed area 51 and is therefore not transparent to light. The black printed area usually has a height of between 5 and 30 cm from the lower edge of the windshield 204.

[0062] The upper side of the display screen 172 can be substantially flush with the upper side of the black printed area of the windshield 204 or be located vertically below the black printed area. In particular, the upper edge and the lower edge of the display screen 172 can be curved in order to correspondingly mimic the curvature of the windshield 204 along the vehicle width direction.

[0063] Based on the above schematic explanations regarding the PHUD architecture, the PHUD is able to provide a wider display area, i.e. is able to substantially cover the width range of the black printed area 51 of the lower part of the windshield 204, i.e. the field of view of the driver extending from the left A-pillar of the vehicle to the right A-pillar of the vehicle. Within such a wide display area, more display content can be provided compared to current HUDs.

[0064] In the current related solutions, there are many solutions for displaying the charging status of the vehicle when it is parked at a charging station or a charging post for charging, but there is no display control solution for the dynamic charging status of the vehicle when it is driving and charging wirelessly. The present disclosure expects to display the charging status of the vehicle during dynamic charging by combining the PHUD, which can more intuitively enable the driver to perceive and understand the charging status of the dynamic charging process.

[0065] Based on this, referring to FIG. 5, a display control method provided by the present disclosure is shown, which can be applied to the display control part 160 of a panorama-head-up-display (PHUD) device, and the method can include steps S501 to S503.

[0066] In step S501, when the host vehicle is in a dynamic charging state, a fixed element representing the current energy of the host vehicle is displayed in the center of the target area of the display screen of the PHUD device.

[0067] In the present disclosure, when the host vehicle travels on a road with a transmitting end 21 for providing electric energy laid under the road surface as shown in FIG. 2, the electric power monitoring device 144 monitors whether the charging device 143 receives electric energy transmitted by the transmitting end 21 through an alternating magnetic field or a resonant magnetic field. When the electric power monitoring device 144 monitors that the charging device 143 receives electric energy transmitted by the transmitting end 21 through an alternating magnetic field or a resonant magnetic field, it can be determined that the host vehicle is in a dynamic charging state of charging while traveling, and in the present disclosure, the charging process in this dynamic charging state is referred to as a dynamic charging process.

[0068] In the present disclosure, the target area can include all or part of the display screen 172. Taking the width of the display screen 172 of the PHUD device shown in FIGS. 3 and 4 as an example, the width of the display screen 172 is much larger than the height of the display screen 172, and the overall display screen 172 appears as a long strip as shown in FIG. 6. Taking the entire display screen 172 as the target area as an example, when it is determined that the host 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. 6, the display control part 160 can control a fixed element 61 (such as a fixed circular bubble) to be displayed in the center area of the display screen 172 of the PHUD device, which can represent the energy storage unit 142 of the host vehicle, such as the battery capacity, which is expressed in percentage in the present disclosure. Those skilled in the art should understand that as the dynamic charging proceeds, the capacity (i.e. the value of the percentage) will gradually increase until it reaches the maximum capacity (i.e. the value of the percentage is 100%) that the battery can store.

[0069] In step S502, the dynamic charging parameter of the host vehicle in the dynamic charging state is obtained.

[0070] In the present disclosure, when the host vehicle is in the dynamic charging state, the power monitoring device 144 can also monitor the state parameters of the charging device 143 during the charging process, i.e. the dynamic charging parameters. Exemplarily, the dynamic charging parameters can 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 charging device 143 receiving the electric energy from the transmitting end 21 under the road surface, the transmission power of the transmitting end 21 under the road surface transmitting the electric energy to the charging device 143, etc. In addition, other power parameters that can represent the dynamic charging process can also be considered as dynamic charging parameters, which will not be described herein.

[0071] 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.

[0072] In the present disclosure, in combination with the example shown in FIG. 6, when the target area is the entire display screen 172, the display control unit 160 plays the moving animation on the display screen 172 of the PHUD device according to the dynamic charging parameters. The moving animation shows the process of the moving element 62 moving from the edge of the display screen 172 to the fixed element 61. Specifically, according to the dynamic charging parameters obtained in step S502, the display control unit 160 can correspond the playing parameters of the moving element 62, such as the size and number of the moving element 62, the playing speed of the moving animation (i.e. the moving speed of the moving element), etc. to these dynamic charging parameters, so as to play the moving animation by controlling the corresponding playing parameters, so that the driver can intuitively understand and master the charging process in the dynamic charging state by watching the moving animation. In the present disclosure, as shown by the dashed box in FIG. 6, the moving element 62 can be a small-size bubble or a group of small-size bubbles with a size smaller than the fixed element 61 (the fixed bubble). By playing the moving animation of the small-size bubble or the group of small-size bubbles moving from the edge of the display screen 172 to the fixed bubble in the direction indicated by the arrow, with the repeated playing of the moving animation, the small-size bubble or the group of small-size bubbles will be displayed as being absorbed by the fixed bubble, and the current electric quantity represented by the fixed bubble will be gradually increased with the dynamic charging process, so that the driver can intuitively perceive the current dynamic charging process.

[0073] By the technical solution shown in FIG. 5, the present disclosure combines the PHUD to show the charging state of the host vehicle during the dynamic charging process through the playing of the moving animation of the moving element moving from the edge of the display screen to the fixed element displayed in the central area of the display screen, which can more intuitively enable the driver to intuitively perceive and understand the charging state of the dynamic charging process.

[0074] Based on the technical solution shown in FIG. 5, in some possible implementation manners, the control for the fixed element representing the current power of the vehicle is displayed in the center of the target area of the display screen of the PHUD device, including:

[0075] obtaining a representation of the current power of the vehicle;

[0076] controlling a display parameter of the filling element according to the representation, and displaying the filling element in a filling manner in the fixed element in the center of the target area according to the display parameter.

[0077] For the above implementation manners, specifically, taking the fixed bubble as an example, the filling element can be an image element capable of filling the fixed bubble, such as flowing liquid and the like. The current power of the vehicle can also be represented by different representations, for example, a current remaining power value (in kwh) of the vehicle, a percentage (in percentage) of the current power reaching a maximum value of the power that can be stored by the battery, and a remaining mileage (in km) of the vehicle that can be traveled according to a power currently provided to the electric motor. Taking the percentage as an example, as shown in FIG. 7, the 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 value of the power that can be stored by the battery, so as to represent the current power of the vehicle 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, as shown in FIG. 8, when the current power reaches 60% of the maximum value of the power that can be stored by the battery, “60%” is displayed in the fixed bubble.

[0078] Based on the above implementation manners, in order to enable the driver to more intuitively understand the current power, color can also be used for reminding, and in some examples, the method further includes:

[0079] when the percentage of the current power of the vehicle reaching the maximum value of the power that can be stored by the battery is less than or equal to a first threshold value, controlling the color of the fixed element, the filling element and the moving element to be displayed as a first color;

[0080] when the percentage of the current power of the vehicle reaching the maximum value of the power that can be stored by the battery is greater than the first threshold value and less than or equal to a second threshold value, controlling the color of the fixed element, the filling element and the moving element to be displayed as a second color;

[0081] when the percentage of the current power of the vehicle reaching the maximum value of the power that can be stored by the battery is greater than the second threshold value, controlling the color of the fixed element, the filling element and the moving element to be displayed as a third color.

[0082] In the above examples, the first threshold is less than the second threshold. Exemplarily, the present disclosure sets the first threshold as 10% and the second threshold as 30%. As shown in FIG. 9, when the current power of the host vehicle reaches a percentage of the maximum power that the battery can store less than 10%, it indicates that the current power is too low to support the host vehicle to travel a long distance, and the urgency of the host vehicle to be charged with high power is high, so the driver is prompted to avoid any driving operation that causes high power consumption during driving by the warning first color, for example, the red color shown in the left image of FIG. 9, 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 host vehicle reaches a percentage of the maximum power that the battery can store greater than 10% and less than or equal to 30%, it indicates that the current power, although low, can still support the host vehicle to travel a long distance, so the driver is prompted to pay attention to reducing the power consumption of the driving operation and to find a charging pile or charging station for charging within the long distance by the second color with low urgency, for example, the yellow color shown in the middle image of FIG. 9. When the current power of the host vehicle reaches a percentage of the maximum power that the battery can store greater than 30%, it indicates that the current power is sufficient, and there is no need to pay attention to the power consumption of the driving operation or to find a charging pile or charging station with higher charging efficiency for charging as the dynamic charging process proceeds, so the third color, such as green, which is not perceived by the human body to cause a sense of urgency, is displayed as shown in the right image of FIG. 9.

[0083] Based on the technical solution shown in FIG. 5, in addition to the display control of the fixed element, the display of the moving element also needs to be controlled. In some possible implementation manners, when the dynamic charging parameter includes the instantaneous power of the charging device of the host vehicle to the energy storage unit during the dynamic charging process, the playing parameter of the moving animation of the moving element moving from the edge of the target area to the fixed element according to the dynamic charging parameter includes:

[0084] determining the display size of the moving element according to the upper and lower limits of the size of the moving element and the instantaneous power;

[0085] taking the display size of the moving element as the playing parameter for controlling the display of the moving animation.

[0086] For the above implementation manners, in the present disclosure, the size of the moving 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 by a current value, and the larger the instantaneous power, the larger the moving element. In some examples, the upper and lower limits of the size of the moving element are set as S max and S min , respectively. Those skilled in the art should understand that S maxSmaller than the size of the aforementioned fixed element. During charging, the instantaneous power also falls within the upper and lower limits, respectively designated as P in this disclosure. max and P min Based on the instantaneous power P and the two upper and lower limits mentioned above, when the target area is the entire display screen, the size of the moving element is obtained according to the following formula. :

[0087] It should be noted that in some examples, when the target area is part of the display screen, the size of the moving element can be based on... The size of the moving element is reduced according to the proportion of the target area to the screen. The proportion of the target area to the screen is set to m. The size of the moving element is determined when the target area is part of the screen. It can be obtained through the following formula:

[0088] .

[0089] Those skilled in the art should understand that, Substitute the calculation formula It can still be seen that, regardless of whether the target area is the entirety 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.

[0090] Based on the above implementation, in addition to the size of the moving elements, 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 vehicle's charging equipment charging the energy storage unit during dynamic charging, the playback parameters for controlling the moving elements to move from the edge of the target area to the fixed element according to the dynamic charging parameter include:

[0091] Obtain the display scaling constant according to the display parameters of the target area of ​​the display screen;

[0092] The number of moving elements in the motion animation is determined based on the display scaling constant and instantaneous power.

[0093] The number of moving elements is used as a playback parameter to control the display of the moving animation.

[0094] In this disclosure, the display scaling constant is used to control the number of moving elements to achieve a better effect on the PHUD display screen. It is typically related to the width, length, and refresh rate of the target area on the display screen. Specifically, taking a moving bubble as an example, the scaling 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; proportionality constant. is inversely proportional to the height H of the target area, ensuring that the vertical distribution of the moving bubbles is reasonable; the proportional constant is associated with the refresh rate , which can affect the generation and smoothness of movement of the moving bubbles. A higher refresh rate allows more moving bubbles to move smoothly, thereby optimizing the dynamic display effect. In some examples, taking the entire display screen as the target area, the width of the target area is the width L of the display screen, the height of the target area is the height H of the display screen, and the refresh rate of the display screen is , based on the above display parameters, the display proportional constant can be obtained by the following formula

[0095]

[0096] wherein, and are adjustment coefficients for adjusting according to specific visual effect requirements. represents the influence adjustment coefficient of the aspect ratio on the number of bubbles; represents the influence adjustment coefficient of the refresh rate on the number of bubbles.

[0097] After obtaining the display proportional constant , the number of moving elements can be calculated according to the following formula , in combination with the instantaneous power P:

[0098] .

[0099] In some examples, when the target area is a part of the display screen, the number of moving elements can be reduced according to the proportion of the target area in the display screen. Assuming that the proportion of the target area in the display screen is n, when the target area is a part of the display screen, the number of moving elements can be obtained by the following formula:

[0100] .

[0101] Those skilled in the art should understand that substituting the calculation formula of into , it can be seen that, regardless of whether the target area is the entire display screen or a part of the display screen, the number of moving elements is still only related to the display proportional constant and the instantaneous power.

[0102] Based on the above two implementation manners, taking the moving bubbles as an example, when the number of moving bubbles is larger and the size is larger, the driver can have the perception that the charging power is larger during the process of watching the moving animation, so that the driver can intuitively perceive the charging power.

[0103] ​Based on the technical solution shown in FIG. 5, when the dynamic charging parameter includes the receiving power of the charging device of the host vehicle receiving the electric energy from the transmitting end under the road surface during the dynamic charging process and the transmission power of the transmitting end under the road surface transmitting the electric energy to the charging device, the playing parameter of the moving animation of the moving element moving from the edge of the target area to the fixed element according to the dynamic charging parameter includes:

[0104] The charging efficiency is obtained according to the receiving power and the transmission power;

[0105] The moving speed of the moving element is obtained according to the charging efficiency and the reference speed of the moving element;

[0106] The display size of the moving element is taken as the playing parameter of controlling the display of the moving animation.

[0107] For the above implementation, during the dynamic charging process, the charging efficiency is the ratio of the receiving power to the transmission power , that is . The reference speed of the moving element can be the moving speed set when the charging efficiency is 100%. Based on the charging efficiency and the reference speed, the moving speed of the moving element can be obtained. Therefore, when the charging efficiency is higher, the moving speed of the moving element is faster, and the driver can intuitively perceive the charging efficiency by the moving speed of the moving element during the viewing of the moving animation.

[0108] In some examples, taking the moving bubble 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 bubble is associated with the width of the target area, so that the moving speed of the moving bubble can not only reflect the efficiency of wireless charging, but also show natural and easy-to-read dynamic effects in the target area. Taking the entire display screen as the target area, the width of the display screen is (unit: pixel), the moving bubble needs to move from one end of the screen to the fixed element (i.e., the center position of the display screen) within a certain time in the high-efficiency charging (100% efficiency) state, and the reference speed can be defined as:

[0109]

[0110] In the specific implementation process, the time T can be optimized according to user experience and display effect, and is usually between a few seconds. In the high-efficiency charging (i.e., the charging efficiency is 100%), the dynamic bubble speed is the reference speed When the charging efficiency changes, the moving speed of the moving bubble is proportional to the charging efficiency, that is:

[0111] .

[0112] In the implementation process, the base time may be appropriately shortened to avoid slow movement of the bubble.

[0113] In some examples, when the target area is a part of the display screen, in addition to being able to reduce V1 according to the proportion of the target area to the display screen according to the foregoing implementation manner, since the width of the target area occupies fewer pixels at this time, the moving speed of the bubble can also be set to a fixed constant value, which can be determined according to actual conditions.

[0114] In addition to the above implementation manners and examples, in some examples, the remaining charging time can also be estimated according to the current power and dynamic charging parameters, and the remaining charging time is displayed in the fixed element. Specifically, the representation of the current power is the remaining mileage, the remaining mileage is 356km, and the remaining charging time is 21 minutes, as shown in FIG. 10, based on the above example, “356km” and “21min” can be displayed in the fixed bubble.

[0115] It should be noted that when the target area is a 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 comprises: displaying the specific value of the representation of the current power of the vehicle and / or the remaining charging time in an area outside the moving animation. Specifically, still taking the remaining mileage as 356km and the remaining charging time as 21 minutes as an example, as shown in FIG. 11, “356km” and “21min” are not displayed in the fixed bubble, nor in the playing area of the moving animation shown in the dashed box, but outside the target area shown in the dashed box.
