[0022] The solutions provided in this application are specifically illustrated through the following embodiments. It should be noted that the order of description of the following embodiments is not intended to limit the preferred order of the embodiments.

[0023] This embodiment will be described from the perspective of a charge / discharge information prompting device, which can be integrated into an electronic device.

[0024] Please see Figure 2 , Figure 2 This is a flowchart illustrating the charging / discharging information prompting method provided in an embodiment of this application. The charging / discharging information prompting method includes: Step S101: Based on the vehicle's charging and discharging information, control the vehicle's light-emitting components to emit light using light-emitting parameters that characterize the charging and discharging information, and control the vehicle's projection components to project and display the projected content characterizing the charging and discharging information.

[0025] The charging and discharging information can describe the charging and discharging status of the vehicle. The light-emitting component can be a light-emitting element, such as a light-emitting diode (LED). Under different charging and discharging information, the light-emitting component is configured to display different lighting effects based on different lighting parameters, indicating the corresponding charging and discharging information based on the different lighting effects. The lighting parameters can be the parameters used by the light-emitting component to emit light. The projection component can be a component used for projection. The projected content can be the content projected by the projection component. The projection component can be configured to project different content based on different charging and discharging information, indicating the corresponding charging and discharging information based on the different projected content.

[0026] Optionally, the emission parameters may include emission frequency and / or emission color. The emission frequency can be the frequency at which the light-emitting component emits light. The emission color can be the color of the light emitted by the light-emitting component.

[0027] In one embodiment, the light-emitting component and the projection component can be deployed on the external components of the vehicle. For example, the light-emitting component can be on the first external component of the vehicle, and the projection component can be on the second external component of the vehicle.

[0028] The first external component can be an external component on the vehicle that has a light-emitting component deployed thereon. The second external component can be an external component on the vehicle that has a projection component deployed thereon.

[0029] In one embodiment, the first external component and the second external component can be external components of the vehicle, such as exterior rearview mirrors, doors, door handles, and other structural components deployed on the outside of the vehicle.

[0030] Optionally, the first external component and the second external component can be the same external component. For example, the first external component and the second external component can be the exterior rearview mirror of a vehicle.

[0031] In one embodiment, the light-emitting component can be an LED light on the exterior rearview mirror. The projection component can be a projection light on the exterior rearview mirror. For example, it can be a projection light on a vehicle used to project a logo or other signage.

[0032] For example, please refer to Figure 3 , Figure 3 This is a schematic diagram of an exterior rearview mirror for a charging and discharging information prompting method provided in an embodiment of this application. The first external component and the second external component can be the exterior rearview mirror of a vehicle. The light-emitting component can be the turn signal 11 on the exterior rearview mirror, and the projection component can be the logo projection light on the exterior rearview mirror.

[0033] Optionally, the charge / discharge information includes charge / discharge status and / or energy parameters.

[0034] The charging / discharging state can refer to the state in which the vehicle is charging or discharging. For example, this state can include at least one of the following: charging / discharging in progress, scheduled charging / discharging, abnormal charging / discharging (or charging / discharging malfunction), charging without charging, and charging without plugging in. Taking the charging state as an example, it can include states such as charging in progress, scheduled charging, abnormal charging, charging without charging, and charging without plugging in. Vehicle discharging can include the vehicle supplying power to external devices, such as other vehicles or mobile phones. The power parameter can indicate the vehicle's power level during charging or discharging, such as the percentage of power that can charge the vehicle, or the percentage of power supplied to other vehicles or mobile phones.

[0035] In one embodiment, the charge / discharge information can be determined by at least one of the following: Is the vehicle plugged in but not charging? Is the vehicle in a scheduled charging state? Is the vehicle charging or discharging? The vehicle's electrical parameters during charging and discharging; Is the vehicle in an abnormal charging / discharging state?

[0036] Optionally, the projection content may include at least one of a first character projection pattern, a second character projection pattern, and a light effect projection pattern. The first character projection pattern can be used to characterize the charging and discharging state of the vehicle, and the second character projection pattern can be used to characterize the vehicle's power parameters.

[0037] The first and second character projection patterns can be text-based projection patterns. For example, when the vehicle is in a scheduled charging state, the first character projection pattern can be a character projection pattern including the text "Scheduled Charging". When the vehicle is in a charging / discharging abnormal state, the first character projection pattern can be a character projection pattern including the text "Charging / Discharging Failure". When the vehicle is in a charging state, assuming the vehicle's battery level is 90%, the second character projection pattern can be a character projection pattern including the text "90" or "90%". The light effect projection pattern can be a graphic projection pattern, such as a ring-shaped light spot or a circular light spot.

[0038] In one embodiment, when the vehicle is in a charging / discharging state (not in a charging / discharging state), the projection content may include a first character projection pattern representing the charging / discharging state; when the vehicle is in a charging / discharging state, the projection content may include a second character projection pattern representing the power parameters.

[0039] Optionally, there are several ways to determine the vehicle's battery parameters. For example, the vehicle's battery parameters can be determined by the connection confirmation signal voltage between the vehicle and the charging / discharging interface component when the vehicle is in a charging / discharging state.

[0040] The charging / discharging interface component can be a component for charging or discharging the vehicle, such as a charging gun, charging socket, or discharging gun. For example, when the vehicle is charging, the charging / discharging interface component can be a charging gun or a charging socket; when the vehicle is discharging, the charging / discharging interface component can be a discharging gun. The connection confirmation signal voltage can be the voltage of the vehicle's connection confirmation (CC) signal, which can be a real-time detected value. The CC signal can be a signal that determines the connection status by measuring the resistance value at the vehicle end or the charging gun end.

[0041] Optionally, the vehicle's connection confirmation signal voltage can be measured using a CC resistor sampling line. This CC resistor sampling line can refer to the CC signal line and the resistor network that works with it to form a voltage divider sampling circuit. For example, the CC resistor sampling line can be a wire connecting the sampling resistor to the voltage detection terminal of the on-board charger (OBC).

[0042] There are several ways to determine the vehicle's battery level parameters by using the connection confirmation signal voltage between the vehicle and the charging / discharging interface component. For example, the vehicle's battery level parameters can be calculated using the connection confirmation signal voltage between the vehicle and the charging / discharging interface component, the lower limit of the connection confirmation signal voltage of the charging / discharging interface component in standby mode, and the upper limit of the connection confirmation signal voltage in fully charged mode.

[0043] The lower limit of the connection confirmation signal voltage can be the connection confirmation signal voltage value of the charging / discharging interface component in standby mode, i.e., the minimum value of the connection confirmation signal voltage. The upper limit of the connection confirmation signal voltage can be the connection confirmation signal voltage value of the charging / discharging interface component in fully charged mode, i.e., the maximum value of the connection confirmation signal voltage.

[0044] There are several ways to calculate the vehicle's battery level parameters using the connection confirmation signal voltage between the vehicle and the charging / discharging interface component, the lower limit of the connection confirmation signal voltage in standby mode, and the upper limit of the connection confirmation signal voltage in fully charged mode. For example, the difference between the connection confirmation signal voltage and the lower limit of the connection confirmation signal voltage can be calculated to obtain a first difference, and the difference between the upper limit of the connection confirmation signal voltage and the lower limit of the connection confirmation signal voltage can be calculated to obtain a second difference. The ratio of the first difference and the second difference can be calculated and multiplied by 100% to obtain the vehicle's battery level parameters.

[0045] Optionally, there are several ways to control the projection component of the vehicle to project and display the projected content representing charging and discharging information. For example, the projection component can be controlled to display the projected content representing charging and discharging information with a target projection brightness, which is determined based on the ambient light brightness of the environment in which the vehicle is located.

[0046] The target projection brightness can be the brightness of the projection component. The ambient light brightness can be the brightness of the ambient light in the vehicle's environment.

[0047] In this way, by determining the target projection brightness of the projection component based on the ambient light brightness of the vehicle's environment, the viewing distance of the projected content can be effectively improved, achieving high visibility in strong light environments. At the same time, light pollution and resource waste can be avoided in low light environments.

[0048] Optionally, the target projection brightness can be determined based on the ambient light brightness of the vehicle's environment and the reference brightness.

[0049] For example, the difference between ambient light brightness and a preset ambient light brightness threshold can be calculated, multiplied by a preset scaling factor, and then added to a reference brightness to obtain the target projection brightness.

[0050] The specific values ​​of the reference brightness, ambient light brightness threshold, and preset proportional coefficient can be set according to actual conditions, and are not limited in this embodiment.

[0051] In one embodiment, taking a charging scenario as an example, to address the technical problems of discontinuous power indication, poor external visibility, and lack of multi-state feedback in related technologies, this application provides a multi-scenario dynamic charging status indication system based on an exterior rearview mirror. By integrating an LED array based on RGB color mode, an ambient light sensor, and multi-protocol communication technology, it achieves dynamic indication of charging percentage, differentiation of multiple scenario states, and high visibility charging status feedback in strong light environments. Please refer to... Figure 3 The charging indicator light 11 (i.e., the light-emitting component) on the exterior rearview mirror can be composed of an array of three RGB LEDs packaged in a 5050 package, achieving a dynamic light effect of battery percentage (0-100% continuous gradient). The logo projection light 12 (i.e., the projection component) integrates a 5-watt (W) LED light source packaged in a chip-on-board (COB) manner, projecting a light spot onto the ground, achieving visibility up to 5 meters in strong light and providing scene-based text prompts. For example, please refer to... Figure 4a , Figure 4aThis is a schematic flowchart illustrating a charging / discharging information prompting method provided in this application embodiment. After the system is powered on, it undergoes power-on initialization. The Vehicle Control Unit (VCU) and Body Control Module (BCM) first establish communication and calibrate the ambient light sensor. Subsequently, during the charging detection phase, the CC resistor sampling line detects voltage changes. The vehicle's charging system reflects the charging progress in real time through changes in the CC signal voltage (i.e., the connection confirmation signal voltage), triggering the OBC to send a plug-in signal. Next, the VCU receives voltage / current data from the OBC via the Controller Area Network (CAN) bus, based on the CC resistor sampling line voltage (… Calculate the percentage of battery charge (i.e., battery charge parameter):

[0052] Among them, the CC signal voltage of the charging socket (real-time detection value) The lower limit of the CC voltage in the standby state of the plug-in device. The upper limit of CC voltage when fully charged .

[0053] Thus, based on the SOC (State of Charge) parameter, the BCM (Bright Module Control) uses Pulse Width Modulation (PWM) technology to control the duty cycle of the RGB LEDs, driving the charging indicator on the exterior rearview mirror to execute dynamic lighting effect logic. For example, please refer to Table 1 below: Table 1

[0054] The BCM (Brightness Control Center) can simultaneously collect ambient light intensity (0-100,000 lux) in real time from an ambient light sensor. Lux is a unit of illuminance. It then dynamically adjusts the LED brightness to control the logo projection light's brightness using an adaptive brightness adjustment algorithm (PID algorithm). (Target projection brightness) It can be determined by the reference brightness. Preset proportional coefficient Real-time ambient light With preset ambient light threshold The formula for calculating the target projection brightness, as jointly determined, is:

[0055] in, This is a preset scaling factor (typically 0.1~1.0). With a fixed ambient light threshold (typically 1000 lux), this formula can dynamically adjust screen brightness by compensating for changes in ambient light in real time, with a response time ≤200 milliseconds (ms).

[0056] Optionally, the dynamic projection lighting effect logic of the projector lamp can be referenced in Table 2 below: Table 2

[0057] The light spot effect refers to the effect obtained by projecting a pattern using the projector lamp. This brightness can be the target projection brightness used by the projector lamp, and can be roughly calculated directly based on the ambient light sensor value and the corresponding scaling factor (e.g., 0.2, 0.15, 0.25). This scaling factor can be set according to actual conditions or empirical values, and is not limited in this embodiment. 50-200 lumens, 100-150 lumens, etc., can represent the brightness range.

[0058] In one embodiment, a multi-scenario dynamic charging status indication system based on an exterior rearview mirror comprises a charging socket, a CC resistor sampling line, an on-board charger (OBC), a vehicle control unit (VCU), a body control unit (BCM), an exterior rearview mirror charging indicator light, and a logo projection light. For example, please refer to... Figure 4b , Figure 4b This is a hardware interaction diagram of a charging and discharging information prompting method provided in this application embodiment. In this method, the charging socket can be connected to the voltage detection terminal of the OBC via the CC resistor sampling line. The OBC transmits charging voltage and current signals to the VCU via the CAN bus at a baud rate of 500 kilobits per second (kbps). The VCU calculates the power percentage based on the voltage of the CC resistor sampling line and sends a status command to the BCM via the Serial Communication Interface (SCI) at a baud rate of 9600 bits per second (bps). When the vehicle is powered on, the BCM receives the status command sent by the VCU and drives the RGB LED array of the exterior rearview mirror charging indicator (e.g., turn signal) to achieve the corresponding light effect. At the same time, it controls the logo projection light to synchronously project light spots and project text indicating the charging status.

[0059] When the Body Controller (BCM) detects that the vehicle is charging, it can set the charging indicator light to be solid red when the battery percentage is 0-10%, output an orange pulsating command (frequency 2Hz±0.2Hz) when the battery percentage is 10-50%, output a yellow breathing command (cycle 3 seconds±0.5 seconds) when the battery percentage is 50-90%, and output a solid green command when the battery percentage is 90-100%. Simultaneously, the logo projection light can project a ring-shaped light spot and display the real-time battery percentage. The brightness of the light spot can automatically adjust within the range of 50-200 lumens based on the ambient light sensor value, ensuring clear identification of the charging status at a distance of 5 meters in strong light conditions. When the BCM detects that the charging gun is not plugged in, it can set the charging indicator light on the exterior rearview mirror to turn off and the logo projection light to shut down. When the BCM detects a charging / discharging fault, it can set the charging indicator light on the exterior rearview mirror to flash red (frequency 4Hz±0.3Hz), and the logo projection light to project a red light spot and project the word "Fault" while flashing. When the BCM detects a scheduled charging scenario, it can output a slow blue flashing command (frequency 0.5Hz±0.1Hz), project a blue light spot onto the logo, and project the text "Scheduled". When the BCM detects a scenario where the charging gun is plugged in but not charging, it can output a white breathing command (cycle 3 seconds±0.5 seconds).

[0060] The following technical defects exist in relevant electric vehicle charging status indication solutions: First, the power level indication is discontinuous. Traditional solutions often use a single-color LED (red / green dual-color) integrated into the charging socket, which can only distinguish between charging and fully charged states, and cannot reflect changes in the power percentage (such as 30%, 70%, etc.), making it impossible for users to intuitively grasp the charging progress. Second, external visibility is poor. Existing LED indicator lights have a visibility distance of less than 3 meters in strong light environments (such as direct sunlight), making it difficult for users to identify the charging status from a distance. Moreover, the light effect is monotonous and cannot convey information through changes in light color (such as gradual change, breathing, pulsation). The traditional solution suffers from several drawbacks. First, it presents complex information, increasing the user's understanding cost. Second, it lacks multi-state feedback, failing to cover various sub-scenarios such as scheduled charging, charging not started, and charging / discharging malfunctions, leading to blind spots in user judgment of charging status. Third, the placement of charging indicator lights is limited. While some solutions place them at the charging port, requiring users to approach to obtain information, placing them on the D-pillar only covers a few high-end models. Projecting charging information onto the windshield significantly increases costs. Adding indicator light components to the rearview mirror itself requires new molding, further increasing hardware costs. Therefore, in traditional solutions, users rely on the charging progress bar displayed on the vehicle's dashboard for charging / discharging information, lacking real-time external feedback. This forces users to enter the vehicle to check, and makes it impossible to distinguish between scheduled charging and malfunctions, further exacerbating user uncertainty about the charging status.

[0061] To address this, this application provides a method for displaying charging and discharging information based on an exterior rearview mirror. This method dynamically indicates the battery percentage, differentiates between multiple scenarios, and provides high visibility outside the vehicle in bright light conditions. It utilizes an RGB LED array to achieve continuous 0-100% illumination (0-10% red constant, 10-50% orange pulsating, 50-90% yellow breathing, 90-100% green constant) and dynamically projects scene text (such as "31%", "Reservation in Progress", "Fault") using a logo projection light, covering various charging and discharging states. Through the dual-modal collaborative logic of the RGB LED illumination on the exterior rearview mirror and the logo projection text, the information dimension is enhanced: expanding from one dimension (battery status) to two dimensions (illumination + text). Users no longer need to guess the vehicle's charging and discharging status; the logo projection text is immediately visible. Users also do not need to be near the charging port; they can obtain real-time charging information from outside the vehicle, thus intuitively understanding the vehicle's charging and discharging status and effectively reducing the misjudgment rate of charging and discharging status.

[0062] Optionally, in this embodiment, the turn signal of the exterior rearview mirror is used as a charging indicator light, eliminating the need for re-molding and effectively avoiding increased hardware costs.

[0063] Furthermore, in the charging and discharging information prompting method provided in this application embodiment, the brightness of the projection lamp can be adjusted in real time by the ambient light sensor through a proportional-integral-differential (PID) control algorithm, thereby enabling the projection brightness to automatically match the ambient light and achieve full-scene adaptation. At the same time, no additional sensors or communication modules are required, and the data of the ambient light sensor can be directly reused, avoiding increased hardware costs and thus effectively improving the efficiency of vehicle charging and discharging information prompting.

[0064] As can be seen from the above, the embodiments of this application control the vehicle's light-emitting components based on the vehicle's charging and discharging information, causing them to emit light using light-emitting parameters that characterize the charging and discharging information, and control the vehicle's projection components to project and display the projected content characterizing the charging and discharging information. Therefore, by driving the light-emitting and projection components on the vehicle's external components to display information based on the vehicle's charging and discharging information, users can conveniently and intuitively obtain the vehicle's charging and discharging information, thereby effectively improving the efficiency of vehicle charging and discharging information prompts.

[0065] In one embodiment, this application provides a controller that stores a computer program. When the computer program is executed by a processor, it can implement the steps of the charging and discharging information prompting method provided in this application.

[0072] Optionally, the light-emitting component may include a turn signal deployed on the exterior rearview mirror.

[0073] Optionally, the projection component may include a projection lamp deployed on the exterior rearview mirror.

The meanings of the terms used are the same as in the charging and discharging information prompting method described above, and specific implementation details can be found in the descriptions in the method embodiments.

[0075] For example, such as Figure 5 The diagram shown is a structural schematic of the charging and discharging information prompting device provided in this application embodiment. The charging and discharging information prompting device may include a prompting module 201, as detailed below: The prompt module 201 is used to control the vehicle's light-emitting components to emit light using light-emitting parameters that characterize the charging and discharging information, and to control the vehicle's projection components to project and display the projected content that characterizes the charging and discharging information.

[0076] In one embodiment, the emission parameters include emission frequency and / or emission color.

[0077] In one embodiment, the projection component of the vehicle control unit projects and displays projection content representing charging and discharging information, specifically for: The control projection component displays the projected content representing charging and discharging information at a target projection brightness, which is determined based on the ambient light brightness of the vehicle's environment.

[0078] In one embodiment, the target projection brightness is determined based on the ambient light brightness of the vehicle's environment and a reference brightness.

Conversely, the microphone converts collected sound signals into electrical signals, which are then received by audio circuitry 305, converted back into audio data, and then processed by processor 301 before being transmitted via radio frequency circuitry 304 to, for example, another electronic device, or output to memory 302 for further processing. Audio circuitry 305 may also include an earphone jack to facilitate communication between peripheral headphones and electronic devices.
