[0027] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

The terms “first,” “second,” and similar terms used in this disclosure do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Similarly, the terms “an,” “a,” or “the,” and similar terms do not indicate a quantity limitation, but rather indicate the presence of at least one. The terms “including,” “comprising,” or “containing,” and similar terms mean that the element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects. The terms “connected,” “linked,” or similar terms are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. The terms “upper,” “lower,” “left,” and “right,” etc., are used only to indicate relative positional relationships, and these relative positional relationships may change accordingly when the absolute position of the described objects changes.

[0029] With the development of intelligence, electrification, and connectivity, smart cockpit technology has become a major component of driving equipment (e.g., automobiles). A crucial part of the smart cockpit is glass, including front and rear windshields, sunroofs, side windows, and sun visors. As technology advances and user demands increase, automotive glass needs to possess more and more functions. For example, in addition to the conventional function of light transmission, automotive glass also needs to display images and interact with the user. Automotive glass with display and interactive functions requires the integrated use of technologies such as thin-film transistor arrays, display control, and multi-color pixels. For instance, using dimming glass in vehicles, in addition to the conventional function of light transmission, also enables image display and user interaction.

[0030] Technologies used in smart glass include polymer-dispersed liquid crystal (PDLC), electrochromic (EC), and suspended particle (SPD) technology. PDLC smart glass entered mass production earlier and is relatively inexpensive, achieving both transparent and frosted effects. When powered on, the polymer-dispersed liquid crystal molecules are ordered, allowing light to pass directly through the glass; when powered off, the molecules are disordered, scattering light and creating a frosted effect. PDLC smart glass is typically whitish in color, and when frosted, it presents a soft, natural light. SPD smart glass uses suspended particles that absorb over 99% of visible light. When powered off, the glass is frosted; when powered on, the suspended particles align (orderly), allowing light to pass through. SPD smart glass enables continuously adjustable light. However, due to the characteristics of the suspended particles, SPD smart glass requires 110V and necessitates more robust safety measures, directly increasing costs. SPD smart glass is generally blue, giving it a different appearance from PDLC glass. In EC (electrochromic) dimming glass, the light transmittance is adjusted by utilizing color changes produced by materials and an electric field. EC dimming glass consists of three parts: an ion storage layer, a solid electrolyte, and an electrochromic layer, and features low voltage, low haze, and power-off memory. Under the influence of an electric field, the reflectivity, transmittance, and absorptivity of the electrochromic layer change, thereby altering the light passing through the glass. EC dimming glass primarily comes in gray and blue. The dimming glass mentioned in the embodiments of this disclosure can be any of the aforementioned types of glass.

[0031] In the realm of driving, there are usually bicycle lanes or pedestrian lanes alongside the motor vehicle lanes, with motor vehicles, bicycles, and pedestrians each using their own designated routes. When the motor vehicle lane becomes congested, or when a motor vehicle needs to stop temporarily, it often temporarily occupies the bicycle lane or pedestrian lane. Motor vehicles occupying bicycle lanes or pedestrian lanes severely impact the experience of cyclists and pedestrians, and may even endanger their safety.

[0032] To address this, this disclosure provides an information prompting method applied to a driving device, which includes a dimming glass. The method uses the dimming glass to alert pedestrians or cyclists to the device's actions, thereby reducing the impact of the device's actions on safety and preventing accidents. The method includes: acquiring environmental information of the driving device; determining, based on the environmental information, whether a first target object within an interference range exists in the environment where the driving device is located; acquiring sensor data of the driving device; in response to a change in the sensor data, determining, based on the sensor data, whether the device's action is a preset action; and in response to the presence of a first target object in the environment and the device action being a preset action, displaying a warning message through the first dimming glass. The warning message is used to alert the first target object that the driving device is about to perform or is currently performing a device action.

[0033] Figure 1 illustrates an application scenario of the information prompting method provided by at least one embodiment of this disclosure.

[0034] As shown in Figure 1, vehicle A is traveling in the motor vehicle lane, and bicycle B is traveling in the bicycle lane. Congestion in the motor vehicle lane causes vehicle A to turn right into the bicycle lane. If vehicle A fails to notice bicycle B while turning right, or if bicycle B fails to notice vehicle A turning right, an accident is likely to occur between vehicle A and bicycle B.

[0035] The information prompting method provided by the embodiments of this disclosure can at least partially prevent the occurrence of this accident.

[0036] Figure 2 shows a flowchart of an information prompting method provided by at least one embodiment of the present disclosure.

[0037] As shown in Figure 2, the method includes steps S10 to S50. This method is applied to a driving device, which includes a first dimming glass. This first dimming glass can be a type of dimming glass in the driving device that facilitates viewing by pedestrians. For example, the first dimming glass is a rear windshield, to alert pedestrians located behind the driving device to the operation of the device.

[0038] It should be noted that the terms "first" and "second" in the embodiments of this disclosure are only for distinguishing different concepts and have no limiting effect on this disclosure. The first dimming glass and the second dimming glass can be either dimming glass in the driving device.

[0039] Step S10: Obtain environmental information of the driving equipment.

[0040] Step S20: Based on environmental information, determine whether there is a first target object within the interference range in the environment where the driving equipment is located.

[0041] Step S30: Acquire sensor data from the driving equipment.

[0042] Step S40: In response to a change in sensor data, determine whether the device action of the driving equipment is a preset action based on the sensor data.

[0043] Step S50: In response to the presence of a first target object in the environment and the device action being a preset action, a warning message is displayed through the first dimming glass. The warning message is used to prompt the first target object that the driving device will perform or is performing a device action.

[0044] For step S10, environmental information may include, for example, vehicle information, pedestrian information, or other obstacles in the environment in which the driving device is located.

[0045] For example, if the driving device is a car, environmental information can be obtained through the car's electronic rearview mirror or through onboard radar. This environmental information can be images or videos. For instance, images of the left rear and / or right rear of the driving device can be captured through the electronic rearview mirror.

[0046] For step S20, for example, target detection is performed on the image captured by the electronic rearview mirror, and it is determined whether each detected target is within the interference range. The interference range is, for example, preset, such as the range within 30 meters of the driving device. In some embodiments of this disclosure, the interference range can be determined based on the speed of the driving device, the speed of the target, and the distance between the driving device and the target object. Please refer to the description of Figure 5A below for this embodiment.

[0047] For step S30, the driving equipment may include, for example, a steering sensor, a vehicle lock sensor, etc. Sensor data includes data collected by all sensors installed in the driving equipment. For example, sensor data includes steering data provided by the steering sensor, sensing data provided by the vehicle lock sensor, etc.

[0048] For step S40, preset actions include, for example, unlocking the vehicle lock, turning right, or turning left. For instance, the door lock includes a pressure sensor; if the pressure sensor detects that the pressure reaches a preset pressure, it indicates that the device is unlocking the vehicle lock. As another example, the steering wheel includes an angle sensor; if the angle sensor detects that the steering wheel of the driving device is turned right, it indicates that the device is turning right.

[0049] In some embodiments of this disclosure, the method can be executed by an onboard system installed in the driving device. Before executing the method, the onboard system receives registration requests from the dimming glass, electronic rearview mirror / radar, steering sensor, and vehicle lock sensor, and subscribes to data from the steering sensor / vehicle lock sensor. The onboard system can be a core component of the vehicle's electronic control system, and its main functions include, for example, providing power supply voltage to various sensors; processing input signals from sensors and other devices; storing, calculating, and analyzing processed information; outputting execution commands; outputting fault information; and performing control functions. The onboard system can acquire vehicle driving parameters, such as vehicle speed, and can also acquire sensor parameters of the vehicle itself, such as parameters from collision sensors, water sensors, temperature sensors, pressure sensors, angle sensors, and a range of other sensors. The onboard system needs to process registration requests from different sensors. Registration requests may involve operations such as device authentication, protocol negotiation, and resource allocation. The onboard system may use a central control unit (ECU) or domain controller to manage these sensors. The communication protocols between the vehicle system and various sensors can be, for example, CAN bus, LIN, MOST, or IP-based protocols such as AUTOSAR.

[0050] For step S50, for example, the preset action is to perform an unlocking operation on the vehicle lock. If it is determined from the data of the pressure sensor on the vehicle lock that the user has performed a pressing operation on the vehicle lock, then the device will perform an unlocking operation on the vehicle lock. If there is a first target object in the environment, then a door opening icon will be displayed on the rear windshield to remind the first target object that the door of the driving device is about to open.

[0051] It should be noted that the embodiments of this disclosure do not limit the order of steps S10-S40. For example, steps S10-S20 can be executed first and then steps S30-S40 can be executed, or steps S30-S40 can be executed first and then steps S10-S20 can be executed.

[0052] Figure 3 shows a schematic diagram of a dimming glass displaying warning information provided in at least one embodiment of the present disclosure.

[0053] The dimming glass is, for example, the rear windshield. Of course, the dimming glass can also be the front windshield or a side window, meaning the warning information can also be displayed on the front windshield or a side window. This disclosure does not limit the display location of the warning information.

[0054] As shown in Figure 3(a), the rear windshield displays an arrow indicating that the driving device is turning in the direction the arrow points. In the example in Figure 3(a), the driving device is turning right.

[0055] The icon shown in Figure 3(b) represents, for example, an open door.

[0056] Figure 3 is only an example of a warning message. The warning message can be an icon or text. This disclosure does not limit the form of the warning message.

[0057] In some embodiments of this disclosure, the first dimming glass includes multiple areas. In response to the presence of a first target object in the environment and the device action being a preset action, warning information is displayed through the first dimming glass, including: in response to the presence of a first target object in the environment and the device action being a preset action, the multiple areas alternately display warning information.

[0058] For example, the rear windshield is divided into a left-side and a right-side section, which alternately displays warning information in an emergency. Another example is a rear windshield divided into an upper and a lower section, which also alternately displays warning information in an emergency.

[0059] In this embodiment, it can not only serve the purpose of reminding, but also indicate whether the current road conditions are urgent, thus enriching the function of the warning information and improving the user experience.

[0060] Figure 4A shows a schematic diagram of another dimming glass display warning information provided in at least one embodiment of the present disclosure.

[0061] As shown in Figure 4A, the rear windshield is divided into a first area 401 and a second area 402. Warning information is displayed alternately in the first area 401 and the second area 402.

[0062] For example, the icon in Figure 3(a) is displayed in the first area 401 of the first time period, and the icon in Figure 3(a) is displayed in the second area 402 of the second time period. The first time period and the second time period are two adjacent time periods.

[0063] For example, alternating display of warning messages across multiple zones can be used to indicate an emergency. That is, in an emergency, warning messages are displayed alternately across multiple zones; under normal circumstances (not an emergency), the dimming glass is not zoned, and the warning message is displayed only on the dimming glass itself.

[0064] In some embodiments of this disclosure, the first dimming glass is divided into a left region and a right region, and warning information is displayed through the first dimming glass, including: displaying warning information in the left region to remind the left side of the driving device; or displaying warning information in the right region to remind the right side of the driving device.

[0065] For example, in the example of Figure 4A, the rear windshield is divided into a first area 401 and a second area 402. If it is necessary to alert pedestrians or vehicles located on the right side of the driving device, a warning message is displayed in the first area 401; if it is necessary to alert pedestrians or vehicles located on the left side of the driving device, a warning message is displayed in the second area 402.

[0066] This embodiment can not only achieve the purpose of reminding, but also indicate the object that needs to be reminded, making the warning information more effective.

[0067] In some embodiments of this disclosure, the driving device includes a second dimming glass, and displaying warning information through the first dimming glass includes: displaying warning information by controlling the light transmittance of the first dimming glass and / or the second dimming glass.

[0068] Figure 4B shows a schematic diagram of another dimming glass display warning information provided in at least one embodiment of the present disclosure.

[0069] As shown in Figure 4B, the driving equipment may include a rear windshield (an example of a first dimming glass) and a sunroof (an example of a second dimming glass).

[0070] For example, if the brightness inside the driving equipment is low, the light transmittance of the sunroof can be increased (e.g., by opening the sunroof), thereby enhancing the brightness inside the driving equipment to increase the light entering the rear windshield, so that the rear windshield can clearly display warning information.

[0071] For example, if the high brightness inside the driving equipment dilutes the warning information displayed on the rear windshield, the light transmittance of the sunroof can be reduced so that the warning information can be clearly displayed on the rear windshield.

[0072] Figure 5A shows a flowchart of a method for step S20 in Figure 2 provided by at least one embodiment of the present disclosure.

[0073] As shown in Figure 5A, step S20 includes steps S21 to S23.

[0074] Step S21: Based on environmental information, determine whether the first target object exists in the environment where the driving equipment is located.

[0075] Step S22: In response to the presence of a first target object in the environment where the driving device is located, obtain the distance between the first target object and the driving device and the speed of the first target object.

[0076] Step S23: Based on distance and speed, determine whether the first target object is within the interference range.

[0077] For step S21, for example, target detection is performed on the image captured by the electronic rearview mirror to determine whether there are any objects other than the driving equipment in the image. These other objects can be moving objects (e.g., pedestrians or bicycles) or stationary objects (e.g., rocks, potholes, road signs).

[0078] For step S22, if there are other objects in the environment where the driving device is located, obtain the distance between the first target object and the driving device and the speed of the first target object.

[0079] For step S23, for example, the first speed of the first target object and the second speed of the driving device are obtained; based on the first speed and the second speed, the braking distance is determined; and the warning distance between the first target object and the driving device is obtained. The warning distance refers to the distance between the first target object and the driving device when a warning message is displayed through the dimming glass to serve as a warning. The warning distance can, for example, refer to the distance between the first target object and the driving device at the current moment. For example, if the warning distance is greater than 2.5 times the braking distance, the first target object is not within the interference range; if the warning distance is not greater than 2.5 times the braking distance, the first target object is within the interference range. For example, the braking distance S = (V1 - V2). 2 / 2gμ, V1 is the velocity of the target object, V2 is the velocity of the driving equipment, g = 9.8 m / s 2 μ is the coefficient of friction, with a general value of 10.

[0080] For example, the difference between the first speed and the second speed is calculated; the response time is determined based on the warning distance between the first target object and the driving device; and the first target object is determined to be within the interference range based on the response time.

[0081] Response time T = warning distance / (V2 - V1). If the response time T is greater than 1 minute, the target object is not within the interference range. If the response time T is not greater than 1 minute, the target object is within the interference range.

[0082] Figure 5B shows a flowchart of another information prompting method provided by at least one embodiment of the present disclosure.

[0083] As shown in Figure 5B, the information prompting method includes steps S501 to S516.

[0084] Step S501: The vehicle system receives registration requests from the dimming glass, electronic rearview mirror, steering sensor, and vehicle lock sensor.

[0085] Step S502: The vehicle system subscribes to sensor data from the steering sensor and / or the vehicle lock sensor.

[0086] Step S503: When the data from the steering sensor and / or the vehicle lock sensor changes, the sensor data from the steering sensor and / or the vehicle lock sensor is sent to the vehicle system. For example, when a passenger performs an unlocking operation on the exit lock, the sensor data from the vehicle lock sensor changes; when the steering wheel is turned, the sensor data from the steering sensor changes.

[0087] Step S504: The vehicle system determines whether the lock being unlocked is located on the right side or the steering wheel is turned to the right.

[0088] If the vehicle lock being unlocked is located on the right side or the steering wheel is turned to the right, then step S505 is executed; otherwise, the left-side electronic rearview mirror is controlled to perform target detection.

[0089] Step S505: Control the right-side electronic rearview mirror to perform target detection.

[0090] Step S506: The vehicle system acquires environmental information provided by the electronic rearview mirror. This environmental information may be, for example, image data or video data.

[0091] Step S507: The vehicle system performs target object detection to determine whether a target object exists. If a target object is detected, proceed to the next step S508. If no target object is detected, the driving device performs a device action. Step S507 is similar to step S21 in Figure 5A.

[0092] Step S508: The vehicle system obtains the distance and speed of the target from the electronic rearview mirror.

[0093] Step S509: Determine whether the target object is within the interference range. Steps S508 and S509 are similar to steps S22 and S23 in Figure 5A. If the target object is within the interference range, proceed to step S510. If the target object is not within the interference range, the driving equipment performs the equipment action.

[0094] Step S510: The vehicle system sends a control command to the dimming glass (e.g., the rear windshield) to control the dimming glass.

[0095] Step S511: The dimming glass displays warning information according to the control command. The warning information may include turning, temporary parking, opening the door, etc.

[0096] The embodiments of steps S501 to S511 are similar to the embodiments described in FIG2.

[0097] In other embodiments of this disclosure, the information prompting method, in addition to steps S10 to S50 in FIG2, further includes: after displaying warning information through the first dimming glass, determining the current behavior of the first target object; in response to the current behavior being a preset behavior, prohibiting the driving equipment from performing equipment actions, and displaying passage information through the first dimming glass, the passage information being used to prompt the first target object that safe passage is permitted. The passage information may be, for example, text such as "Safe Passage" or an icon such as a checkmark ("√").

[0098] Displaying traffic information via the first dimming glass includes adjusting warning information to traffic information, or displaying traffic information while displaying warning information.

[0099] For example, after displaying the warning message, the system continues to acquire images from the electronic rearview mirror, and determines the current behavior of the first target object based on the images. Preset behaviors include, for example, turning on the high beams, alternating between high and low beams, and turning on the hazard lights. If the current behavior is one of the preset behaviors, the system controls the driving equipment not to perform any actions (e.g., steering or unlocking the doors). For example, if the current behavior is one of the preset behaviors, the system controls the steering controller to maintain straight driving or the doors to be locked. Furthermore, the system displays traffic information through the dimming glass to indicate that the first target object can pass safely. For details on this embodiment, please refer to steps S512 to S515 in Figure 5B.

[0100] Step S512: The electronic rearview mirror acquires environmental information and sends it to the vehicle system.

[0101] Step S513: The vehicle system determines whether the target object's current behavior is a preset behavior. These preset behaviors indicate that the target object is in a special situation and requires special handling. Preset behaviors include, for example, turning on the high beams, alternating between high and low beams, and turning on the hazard lights. If the target object's current behavior is a preset behavior, then step S514 is executed. If the target object's current behavior is not a preset behavior, then the driving device executes a device action.

[0102] Step S514: The vehicle system controls the steering controller to maintain straight driving or the vehicle locks to be closed.

[0103] Step S515: The vehicle system controls the dimming glass to display safe passage information.

[0104] In this example, steps S507 to S515 are repeated until the driving equipment is turned off.

[0105] This embodiment can avoid the target object when the target object is in a special situation, which improves the flexibility of controlling the driving equipment and further avoids the occurrence of accidents.

[0106] In the example of Figure 5B, the environmental information of the driving device is obtained after it is determined that the device action is a preset action. That is, the environmental information of the driving device is obtained after it is determined that the device action is a preset action. This embodiment does not require the electronic rearview mirror to obtain environmental information in real time; it only needs to obtain environmental information after it is determined that the driving device has performed the device action, thereby saving resources and avoiding waste.

[0107] In other embodiments of this disclosure, acquiring sensor data from the driving device includes: after determining that a first target object within the interference range exists in the environment where the driving device is located, acquiring sensor data from the driving device. In this example, the environmental information of the driving device can be continuously monitored first through an electronic rearview mirror. When the first target object is found in the environmental information, sensor data is acquired to determine whether the driving device should perform a device action. This embodiment can respond quickly, improving response speed.

[0108] Figure 5C shows a flowchart of another information prompting method provided by at least one embodiment of the present disclosure.

[0109] As shown in Figure 5C, the information prompting method includes steps S601 to S612.

[0110] Step S601: The vehicle system receives registration requests from the dimming glass, electronic rearview mirror, steering sensor, and vehicle lock sensor.

[0111] Step S602: The vehicle system subscribes to sensor data from the steering sensor and / or the vehicle lock sensor.

[0112] Step S603: The vehicle system acquires environmental information provided by the electronic rearview mirror. This environmental information may be, for example, image data or video data.

[0113] Step S604: The vehicle system performs target object detection to determine whether a target object exists. If a target object is detected, proceed to the next step S605. If no target object is detected, the driving device performs a device action.

[0114] Step S605: The vehicle system obtains the distance and speed of the target from the electronic rearview mirror.

[0115] Step S606: Determine whether the target object is within the interference range. If the target object is within the interference range, proceed to step S607. If the target object is not within the interference range, the driving equipment performs the equipment action.

[0116] Step S607: The vehicle system sends a control command to the dimming glass (e.g., the rear windshield) to control the dimming glass to display communication information.

[0117] Step S608: Control the dimming glass to display communication information.

[0118] Step S609: When the sensor data of the steering sensor / vehicle lock sensor changes, send the sensor data of the steering sensor / vehicle lock sensor to the vehicle system.

[0119] Step S610: The vehicle system determines whether the lock being unlocked is located on the right side or the steering wheel is turned to the right. If the lock being unlocked is located on the right side or the steering wheel is turned to the right, then proceed to step S611; otherwise, control the left-side electronic rearview mirror to perform target detection.

[0120] Step S611: The vehicle system sends a control command to the dimming glass (e.g., the rear windshield) to control the dimming glass.

[0121] Step S612: The dimming glass displays warning information according to the control command. The warning information may include turning, temporary parking, opening the door, etc.

[0122] The embodiment shown in Figure 5C involves acquiring the sensor data of the driving device after determining that a first target object within the interference range exists in the environment where the driving device is located. That is, the example in Figure 5B first determines whether the vehicle lock is on the right or the steering wheel is turned to the right before determining whether the target object is within the interference range; the example in Figure 5C first determines whether the target object is within the interference range before determining whether the vehicle lock is on the right or the steering wheel is turned to the right.

[0123] In some embodiments of this disclosure, the information prompting method may further include: after determining that a first target object within the interference range exists in the environment where the driving device is located, and before acquiring sensor data from the driving device, displaying passage information through a first dimming glass, the passage information being used to prompt the first target object that safe passage is permitted. As shown in FIG5C, step S608 may also be included between steps S606 and S609.

[0124] The embodiments of Figures 5B and 5C are executed in the same way as the above-mentioned judgment order and step S608.

[0125] Figure 6A shows a flowchart of a method for step S50 in Figure 2 provided by at least one embodiment of the present disclosure.

[0126] As shown in Figure 6A, the method includes steps S51 to S53.

[0127] Step S51: In response to the presence of a first target object in the environment and the device action being a preset action, obtain the first speed of the first target object and the second speed of the driving device.

[0128] Step S52: Determine the urgency level of the warning message based on the first speed and the second speed.

[0129] Step S53: Based on the level of urgency, display a warning message through the first dimming glass.

[0130] This embodiment not only displays warning information from the driving device through the dimming glass, but also expresses the degree of urgency through the display on the dimming glass, increasing the richness of the dimming glass's function and improving the user experience.

[0131] For steps S51 and S52, for example, based on the first speed and the second speed, a braking distance is determined; a warning distance between the first target object and the driving device is obtained. The urgency level for displaying a warning message is determined based on the warning distance and the braking distance. For example, the braking distance S = (V1 - V2). 2 / 2gμ, V1 is the velocity of the target object, V2 is the velocity of the driving equipment, g = 9.8 m / s 2 μ is the coefficient of friction, typically set to 10. For example, the difference between the first speed and the second speed is calculated; the response time is determined based on the warning distance between the first target object and the driving device; and the urgency level is determined based on the response time.

[0132] For example, urgency levels include Level 1 and Level 2. If the warning distance is less than the braking distance, it is Level 1; if the warning distance is less than 1.5 times the braking distance but greater than 1.2 times the braking distance, the urgency level is Level 2. As another example, in addition to Levels 1 and 2, urgency levels also include Level 3. If the warning distance is greater than 2 times the braking distance, the urgency level is Level 3. As yet another example, if the response time is less than 20 seconds, it is Level 1; if the response time is greater than or equal to 20 seconds but less than 30 seconds, it is Level 2.

[0133] For step S53, for example, in response to an urgency level of 1, the first dimming glass flashes a warning message at a first frequency, or flashes a warning message for a first time period; in response to an urgency level of 2, the first dimming glass flashes a warning message at a second frequency, or flashes a warning message for a second time period. The urgency level of 1 is higher than that of 2, and the first frequency is higher than the second frequency. That is, the higher the urgency level, the higher the flashing frequency of the dimming glass, and the first time period is longer than the second time period.

[0134] For example, when the warning distance S1 > 2S, the indication information of the dimmable glass is normally turned on or remains off; this distance is a safe parking distance and does not affect safety; when 1.5S > S1 > 1.2S, the dimmable glass blinks (for example, switches on and off three times consecutively) to display warning information; or the dimmable glass blinks to display warning information at a frequency of once every 2 seconds. When S1 < S, the warning information on the dimmable glass keeps blinking or the dimmable glass blinks to display warning information at a frequency of once every 5 seconds. The above three methods increase the attention degree of indication and reminder by means of case-based division, thereby improving safety.

[0135] In some embodiments of the present disclosure, the information prompting method further comprises: in response to the emergency degree reaching a preset degree, restricting the driving device from performing a device action; and releasing the restriction on the driving device after a preset time.

[0136] For example, the preset degree includes, for example, that the response time is less than 10s. If the response time is less than 10S, the on-board system does not respond to the unlocking system of the alighting lock (that is, the door is locked), and the door is in an unopenable state. For example, after an interval of 5S, the locked state of the door of the on-board system is released; when door opening detection is performed, the dimmable glass on the corresponding side is synchronously adjusted to a transparent state.

[0137] Different reminder levels and different warning modes are set according to the specific situation between pedestrians or vehicles behind and the vehicle, so that the vehicles or pedestrians behind can be effectively prompted, and driving safety is improved.

[0138] Figure 6B shows a flowchart of another information prompting method provided by at least one embodiment of the present disclosure.

[0139] As shown in Figure 6B, the information prompting method comprises steps S701 to S711.

[0140] In this information prompting method, except that step S711 is different from step S511 in Figure 5B, other steps are the same as the corresponding steps in Figure 5B.

[0141] For step S711, the dimmable glass displays warning information in a strobing manner.

[0142] For example, as described above, if the emergency degree is a first level, the warning information is displayed according to a first frequency; if the emergency degree is a second level, the warning information is displayed according to a second frequency.

[0143] In some embodiments of the present disclosure, the information prompting method further comprises: the driving device further comprises a non-driving seat and a second dimmable glass located on a corresponding side of the non-driving seat, the preset action comprises performing an unlocking operation on a door lock of the non-driving seat, and the method further comprises: increasing the light transmittance of the second dimmable glass.

[0144] The driving equipment includes, for example, a non-driving seat and a driving seat. The non-driving seat carries passengers, and the driving seat carries the driver. For instance, in a five-seat vehicle, the driving seat is one seat near the front of the vehicle (e.g., on the left side), the non-driving seats include three seats near the rear of the vehicle and one seat near the front of the vehicle (e.g., on the right side), and the dimming glass includes a windshield, a rear windshield, and four side windows. These four side windows are: a side window on the driver's side, a side window on the non-driving side near the front of the vehicle (referred to as the "right front side"), and two side windows on either side of the non-driving side near the rear of the vehicle (referred to as the "left rear side" and "right rear side"). A second dimming glass corresponding to the non-driving side includes, for example, a left rear side dimming glass, a right rear side dimming glass, and a right front side dimming glass. For example, if the right front side door lock is opened, the light transmittance of the right front side dimming glass is increased, allowing the passenger in the right front seat to clearly see the environment outside the driving equipment.

[0145] For example, the driving device is a segmented unlocking device, which performs unlocking operations on the vehicle lock, such as opening the door by pressing twice or unlocking by pressing continuously.

[0146] In some embodiments of this disclosure, the information notification method further includes: after increasing the light transmittance of the second dimming glass, detecting whether the light transmittance of the second dimming glass meets a requirement; and outputting a notification message in response to the light transmittance of the second dimming glass meeting the requirement. For example, the requirement is that the light transmittance reaches 80%. If the light transmittance of the dimming glass does not reach 80%, the notification message will only be displayed on the driver's seat or non-driver's seat, for example, on a display screen.

[0147] This embodiment performs a self-inspection on the dimming glass to ensure that the light transmittance of the dimming glass is improved.

[0148] In some embodiments of this disclosure, the information prompting method further includes: in response to the device performing an unlocking operation on the vehicle lock in the non-driver's seat, and the presence of a first target object or a second target object in the environment, adjusting the position of the driving device, and then having the control device at the driver's seat unlock the vehicle lock in the non-driver's seat, wherein the first target object is a moving object and the second target object is a non-moving object; or in response to the device performing an unlocking operation on the vehicle lock in the non-driver's seat, and the absence of a first target object or a second target object in the environment, having the control device at the driver's seat unlock the vehicle lock in the non-driver's seat.

[0149] The first target object is, for example, a moving object, such as a pedestrian, cyclist, or other person using a driving device. The second target object includes obstacles such as puddles, pits, rocks, and road signs. For instance, if the device operates to unlock the door of a vehicle outside the driver's seat and there are obstacles in the environment, the driver is notified. The driver then adjusts the position of the driving device and controls the device to unlock the door outside the driver's seat. If the device operates to unlock the door of a vehicle outside the driver's seat and there are no obstacles or moving objects in the environment, the driver directly controls the device to unlock the door outside the driver's seat.

[0150] In some embodiments of this disclosure, the information prompting method further includes: analyzing environmental information to determine the location information of the first target object or the second target object when the device performs an unlocking operation on the vehicle lock in the non-driver's seat and a first target object or a second target object exists in the environment; and displaying the location information to the non-driver's seat.

[0151] For example, if there are puddles in the environment, the image provided by the electronic rearview mirror is analyzed to determine the location of the puddles, and the location of the puddles is displayed on the display screen of the driving device.

[0152] Figure 7A shows a flowchart of a method for unlocking a vehicle from a non-driver's seat according to at least one embodiment of the present disclosure.

[0153] As shown in Figure 7A, the method includes steps S801 to S808.

[0154] Step S801: The non-driver performs the exit lock unlocking operation.

[0155] Step S802: Adjust the corresponding side dimming glass to transparent.

[0156] Step S803: The sensors on both sides of the corresponding side dimming glass detect whether it is transparent. If it is detected as non-transparent, the corresponding head-up display or passenger screen at the driver's or passenger's position is notified.

[0157] Step S804: The vehicle starts the corresponding environmental detection and notifies the driver's seat of the exit side position.

[0158] Step S805: If the environmental detection on the corresponding side is normal, the driver unlocks the door on the corresponding side.

[0159] Step S806: If an abnormality is detected in the corresponding side of the environment, the driver adjusts the vehicle position and actively unlocks the door on the corresponding side (without requiring the corresponding side to request to exit the vehicle and unlock).

[0160] Step S807: If an abnormality is detected in the corresponding side environment, the driver notifies the corresponding person (if there is an obstacle at the corresponding test position, the electronic rearview mirror is adjusted to detect and the position of the obstacle is determined by combining image recognition, and the image of the corresponding position is directly transmitted to the driver's seat or to the passenger screen / to the head-up display screen on the rear seat), and the corresponding door is unlocked.

[0161] In some embodiments of this disclosure, to prevent collisions caused by abnormal exiting the vehicle from the non-driver's seat and improve exiting safety, a dimming glass transparency switch is mainly used, controlled by the driver. This is combined with vehicle sensor detection, using information provided by the vehicle's own sensors for alerts and judgments. The driver makes anomaly judgments and controls the exit to ensure safety. In some embodiments of this disclosure, to prevent collisions when exiting the vehicle from the driver's seat and improve exiting safety, a dimming glass transparency switch is mainly used, combined with vehicle sensor detection. Information provided by the vehicle's own sensors is used for alerts / judgments, including door obstacle and door opening rotation collision signals, detection and speed judgment of moving targets behind the vehicle, and ground elevation / flatness / deep pits / puddles outside the door. For exiting the vehicle from the driver's seat, the core requirement is to detect moving targets and their speed from behind or in front of the vehicle. In some embodiments of this disclosure, environmental judgment, dimming glass, ultra-wideband (UWB) (used to determine precise distance and positioning), and ambient lighting can be combined to achieve the warning purpose. For example, if the vehicle is in a dark environment, the driver gradually approaches the vehicle (e.g., at a distance of 50 meters) to assess the environment and turns on the corresponding side of the dimming glass to the transparent state. If there is abnormal information inside the vehicle (e.g., someone is inside the vehicle), the ambient light will turn yellow and flash as a reminder.

[0162] Figure 7B shows a flowchart of another information prompting method provided by at least one embodiment of the present disclosure.

[0163] As shown in Figure 7B, the information prompting method includes steps S810 to S850.

[0164] Step S810: Obtain environmental information of the driving equipment.

[0165] Step S820: Based on environmental information, determine whether there is a first target object within the interference range in the environment where the driving equipment is located.

[0166] Step S830: Acquire sensor data from the driving equipment.

[0167] Step S840: In response to a change in sensor data, determine whether the device action of the driving device includes a first preset action based on the sensor data.

[0168] Step S850: In response to the presence of a first target object in the environment and the device action not including a first preset action, display passage information through the first dimming glass.

[0169] This method can alert pedestrians or vehicles to the operation of the driving device through the dimming glass. Without including the first preset action, it can promptly notify pedestrians or vehicles other than the driving device that they can drive safely, thereby reducing the impact on the passage of pedestrians or vehicles other than the driving device.

[0170] For steps S810 to S840, please refer to the description above.

[0171] For step S840, the first preset action is, for example, an action that affects the passage of pedestrians or vehicles other than the driving equipment, such as opening a car door or making a U-turn. For example, sensor data includes data provided by the pressure sensor of the car door lock. If the pressure sensor detects a pressure change, the equipment action includes the first preset action (opening the car door); if the pressure sensor does not detect a pressure change, the equipment action does not include the first preset action.

[0172] For step S850, for example, if the device action does not include opening the door, then traffic information is displayed on the dimming glass to indicate to pedestrians or vehicles other than the driving device that they can pass safely.

[0173] The driving equipment also includes an access point, and the first preset action includes opening the access point. The access point is, for example, a vehicle door.

[0174] In some embodiments of this disclosure, step S50 includes displaying warning information and then displaying passage information in response to the presence of a first target object in the environment and the device action including a second preset action but not the first preset action.

[0175] In some embodiments of this disclosure, warning information is used to inform the first target object that the driving device will perform or is performing an action. Warning information can be any information that serves as a prompt, such as text or icons. Passage information is used to inform the first target object that it is safe to pass. Passage information and warning information are different types of information; for example, warning information may be presented in a more prominent manner.

[0176] For example, the device action can be a series of continuous actions, such as turning right and then turning off the engine (i.e., pulling over) or turning right and then opening the door.

[0177] The second preset action includes, for example, turning right or left. For instance, if the device's action is to turn right without opening the side door (i.e., simply pull over to the side without opening the door), then a warning message indicating a right turn will be displayed, followed by traffic information.

[0178] In response to the presence of a first target object in the environment and the device action including both a second preset action and a first preset action, a warning message is displayed.

[0179] If the device's action is to turn right and open the side door (i.e., only park on the side of the road without opening the door), a warning message will be continuously displayed. Figure 8 shows a schematic block diagram of an information prompting device 900 provided in at least one embodiment of this disclosure.

[0180] For example, as shown in Figure 8, the information prompting device 900 includes a first acquisition unit 910, a first determination unit 920, a second acquisition unit 930, a second determination unit 940, and a display unit 950.

[0181] The first acquisition unit 910 is configured to acquire environmental information of the driving device. The first acquisition unit 910 may, for example, execute step S10 as described in FIG2.

[0182] The first determining unit 920 is configured to determine, based on the environmental information, whether a first target object located within the interference range exists in the environment where the driving device is located. The first determining unit 920 may, for example, execute step S20 as described in FIG2.

[0183] The second acquisition unit 930 acquires sensor data from the driving device. The second acquisition unit 930 may, for example, execute step S30 as described in FIG2.

[0184] The second determining unit 940, in response to a change in the sensor data, determines whether the device action of the driving device is a preset action based on the sensor data. The second determining unit 940 may, for example, execute step S40 as described in FIG2.

[0185] Display unit 950 is configured to display a warning message through the first dimming glass in response to the presence of the first target object in the environment and the device action being the preset action. The warning message is used to prompt the first target object that the driving device will perform or is performing the device action. Display unit 950 may, for example, execute step S50 as described in FIG2.

[0186] For example, the first acquisition unit 910, the first determination unit 920, the second acquisition unit 930, the second determination unit 940, and the display unit 950 can be hardware, software, firmware, or any feasible combination thereof. For example, the first acquisition unit 910, the first determination unit 920, the second acquisition unit 930, the second determination unit 940, and the display unit 950 can be dedicated or general-purpose circuits, chips, or devices, or they can be a combination of a processor and a memory.
