Abstract
Description
Technical Field
[0001] This application relates to the field of vehicle technology, and in particular to a method, device and vehicle for illuminating brake lights. Background Technology
[0002] With the increasing popularity of electric and hybrid vehicles, energy recovery has become a crucial technology for improving energy efficiency and reducing emissions. This technology achieves efficient energy utilization by converting some of the kinetic energy of a vehicle during deceleration into electrical energy stored in a battery.
[0003] In actual operation, when the driver releases the accelerator pedal, the vehicle enters a coasting state. If equipped with an energy recovery system, the system will activate at this time, slowing the vehicle down while recovering energy. Because this deceleration does not rely on the traditional braking system, it will not trigger the brake lights. This may confuse drivers behind, making it impossible for them to determine from the brake lights that the vehicle ahead is decelerating, posing a safety risk. Summary of the Invention
[0004] This application provides a method, device, and vehicle for illuminating brake lights. The method provides different illumination modes for different energy recovery levels and driving scenarios, making the brake light illumination more consistent with the current energy recovery level and driving scenario. This allows for accurate reminders of the actual deceleration level to following vehicles, effectively improving the deceleration warning effect of the brake lights, reducing the risk of rear-end collisions caused by speed changes due to energy recovery, and thus improving overall road traffic safety.
[0005] In a first aspect, a method for illuminating brake lights is provided, the method comprising: acquiring the energy recovery level when the energy recovery system is activated and the current driving scenario; determining a target illumination mode for the brake lights based on the energy recovery level and the current driving scenario; determining target illumination parameters for the brake lights based on the target illumination mode, wherein different illumination modes correspond to different illumination parameters; and controlling the brake lights to illuminate based on the target illumination parameters.
[0006] Through the above technical solution, the embodiments of this application can determine the target illumination mode of the brake lights according to the energy recovery level and the current driving scenario, and provide different illumination parameters according to different illumination modes to realize brake light illumination control under different energy recovery scenarios. Since the deceleration degree caused by the vehicle triggering different energy recovery levels under different driving scenarios is different, different illumination modes are provided under different energy recovery levels and driving scenarios, so that the brake light illumination is more in line with the current energy recovery level and the current driving scenario. This can accurately convey the actual deceleration level to the following vehicles, effectively improve the deceleration warning effect of the brake lights, reduce the risk of rear-end collisions caused by changes in vehicle speed due to energy recovery, and thus improve the overall road traffic safety.
[0007] In conjunction with the first aspect, in some possible implementations, the target illumination mode of the brake lights is determined based on the energy recovery level and the current driving scenario, including: if the energy recovery level is less than a preset recovery level, then the target illumination mode of the brake lights is determined based on the current driving scenario; if the energy recovery level is greater than or equal to the preset recovery level, then the target illumination mode of the brake lights is determined based on the energy recovery level.
[0008] Through the above technical solution, since a lower energy recovery level results in a lower degree of vehicle braking deceleration, this embodiment of the application primarily considers the impact of the current driving scenario on deceleration when the energy recovery level is low, and determines the target lighting mode based on the current driving scenario. When the energy recovery level is high, energy recovery has a greater impact on vehicle deceleration, so the target lighting mode is determined based on the energy recovery level. Thus, this embodiment of the application accurately determines the target lighting mode of the brake lights by comprehensively considering the energy recovery level and the degree of impact of the current driving scenario on deceleration, thereby accurately conveying the actual degree of deceleration to following vehicles, effectively improving the deceleration warning effect of the brake lights, and ensuring driving safety.
[0009] Combining the first aspect and the above implementation methods, in some possible implementation methods, determining the target illumination mode of the brake light based on the current driving scenario includes: obtaining a first correspondence table between driving scenarios and illumination modes; and determining the target illumination mode corresponding to the current driving scenario based on the first correspondence table.
[0010] Through the above technical solution, the embodiments of this application can pre-establish a first correspondence table between driving scenarios and lighting modes. The first correspondence table can accurately represent the correspondence between driving scenarios and lighting modes. Thus, by searching the first correspondence table, the target lighting mode matching the current driving scenario can be quickly and accurately determined.
[0011] Combining the first aspect and the above implementation methods, in some possible implementation methods, the target lighting mode determined according to the first correspondence table is the first lighting mode. After determining the target lighting mode corresponding to the current driving scenario according to the first correspondence table, the method further includes: obtaining the current slope of the road where the vehicle is located; if the current slope is greater than the preset slope, then the target lighting mode is modified from the first lighting mode to the second lighting mode.
[0012] The above technical solution addresses the issue that different slopes affect vehicle speed when going downhill. For example, a steep slope increases the speed of a coasting vehicle, and the greater the slope, the greater the impact. If the vehicle decelerates through energy recovery, but a following vehicle continues to accelerate due to the slope, a rear-end collision is likely if the following vehicle fails to slow down. Therefore, this embodiment can modify the first illumination mode to a second illumination mode when the slope is steep. The second illumination mode better alerts following vehicles to slow down, preventing rear-end collisions caused by excessive speed due to steep slopes. This provides different braking illumination modes based on the slope, better adapting to the impact of slope on deceleration alerts and improving road safety.
[0013] Combining the first aspect and the above implementation methods, in some possible implementation methods, the target lighting mode determined according to the first correspondence table is the first lighting mode. After determining the target lighting mode corresponding to the current driving scenario according to the first correspondence table, the method further includes: obtaining the current rainfall of the vehicle's environment; if the current rainfall is greater than the first preset rainfall and less than or equal to the second preset rainfall, then the target lighting mode is modified from the first lighting mode to the third lighting mode; if the current rainfall is greater than the second preset rainfall, then the target lighting mode is modified from the first lighting mode to the fourth lighting mode.
[0014] Through the above technical solution, since the amount of rainfall affects the slipperiness of the road surface and the driver's visibility, and the greater the rainfall, the greater the impact, this application embodiment further determines the target lighting mode according to the amount of rainfall when the vehicle is driving in rainy weather. This better adapts to the impact of rainfall on the deceleration reminder effect. When the rainfall is heavy, the third or fourth lighting mode is used to better remind the following vehicles to slow down, avoiding rear-end collisions caused by slippery roads and poor driving visibility. Thus, different braking lighting modes are provided according to different rainfall amounts to better adapt to the impact of rainfall on deceleration reminders and improve road driving safety.
[0015] In combination with the first aspect and the above implementation methods, in some possible implementation methods, determining the target lighting mode of the brake light based on the energy recovery level includes: obtaining a second correspondence table between the energy recovery level and the lighting mode; and determining the target lighting mode corresponding to the current energy recovery level based on the second correspondence table.
[0016] Through the above technical solution, the embodiments of this application can pre-establish a second correspondence table between energy recovery level and lighting mode. The correspondence between energy recovery level and lighting mode can be accurately represented by the second correspondence table. Thus, by looking up the second correspondence table, the target lighting mode matching the current driving scenario can be quickly and accurately determined.
[0017] In combination with the first aspect and the above implementation methods, in some possible implementation methods, obtaining the energy recovery level when the energy recovery system is started includes: identifying the user's setting result for the energy recovery level; and determining the energy recovery level when the energy recovery system is started based on the setting result.
[0018] Through the above technical solution, the embodiments of this application can provide users with selection prompts for energy recovery levels, identify the energy recovery levels set by the user, and thus determine the energy recovery level according to the user's needs. For example, if the user has a high need for deceleration, a higher energy recovery level can be set; if the user has a high need for gliding, a lower energy recovery level can be set. Thus, the energy recovery level can be determined according to the user's needs, effectively improving the user experience.
[0019] In combination with the first aspect and the above implementation methods, in some possible implementation methods, after controlling the brake lights to illuminate according to the target illumination parameters, the method further includes: generating a brake light illumination prompt.
[0020] Through the above technical solution, the embodiments of this application can generate a brake light illumination prompt, which can make the driver more clearly aware that the brake light has been turned on, enhance the driver's perception of the vehicle status, and thus improve the overall driving experience.
[0021] Secondly, a brake light illuminating device is provided, comprising: an acquisition module for acquiring the energy recovery level when the energy recovery system is activated and the current driving scenario; a determination module for determining the target illumination mode of the brake light based on the energy recovery level and the current driving scenario, and determining the target illumination parameters of the brake light based on the target illumination mode, wherein different illumination modes correspond to different illumination parameters; and a control module for controlling the brake light to illuminate based on the target illumination parameters.
[0022] In conjunction with the second aspect, in some possible implementations, the determining module is further used to determine the target lighting mode of the brake lights based on the current driving scenario if the energy recovery level is less than the preset recovery level; and to determine the target lighting mode of the brake lights based on the energy recovery level if the energy recovery level is greater than or equal to the preset recovery level.
[0023] Combining the second aspect and the above implementation methods, in some possible implementation methods, the determining module is further used to obtain a first correspondence table between driving scenarios and lighting modes; and to determine the target lighting mode corresponding to the current driving scenario based on the first correspondence table.
[0024] In combination with the second aspect and the above implementation methods, some possible implementation methods also include: a first correction module, used to obtain the current slope of the road where the vehicle is located after determining the target lighting mode corresponding to the current driving scenario according to the first correspondence table; if the current slope is greater than the preset slope, the target lighting mode is corrected from the first lighting mode to the second lighting mode.
[0025] In conjunction with the second aspect and the above implementation methods, some possible implementation methods may further include: a second correction module, which, after determining the target lighting mode corresponding to the current driving scenario according to the first correspondence table, obtains the current rainfall of the vehicle's environment; if the current rainfall is greater than the first preset rainfall and less than or equal to the second preset rainfall, then the target lighting mode is corrected from the first lighting mode to the third lighting mode; if the current rainfall is greater than the second preset rainfall, then the target lighting mode is corrected from the first lighting mode to the fourth lighting mode.
[0026] Combining the second aspect and the above implementation methods, in some possible implementation methods, the determining module is further used to obtain a second correspondence table between energy recovery level and lighting mode; and to determine the target lighting mode corresponding to the current energy recovery level according to the second correspondence table.
[0027] In combination with the second aspect and the above implementation methods, in some possible implementation methods, the acquisition module is further used to identify the user's setting result for the energy recovery level; and to determine the energy recovery level when the energy recovery system is started based on the setting result.

[0035] The technical solutions in this application will be clearly and thoroughly described below with reference to the accompanying drawings. In the description of the embodiments of this application, unless otherwise stated, " / " means "or," for example, A / B can mean A or B. "And / or" in the text is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Furthermore, in the description of the embodiments of this application, "multiple" refers to two or more than two.
[0036] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as implying or suggesting relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.
[0037] Figure 1 This is a schematic flowchart of a brake light illuminating method provided in an embodiment of this application.
[0038] For example, such as Figure 1 As shown, the method for illuminating the brake light includes the following steps:
[0039] In step S101, the energy recovery level when the energy recovery system is activated and the current driving scenario are obtained.
[0040] The current driving scenario can be determined based on road conditions, weather conditions, surrounding environment, vehicle condition data, etc. For example, in this embodiment of the application, the road type (urban road, highway, etc.) and terrain features (uphill, downhill) of the vehicle's location can be determined by GPS / map data, and the vehicle's current speed, acceleration and other vehicle condition data and surrounding environment can be determined by the vehicle's built-in sensors.
[0041] Understandably, when a vehicle decelerates, its kinetic energy is typically dissipated as heat through friction. The energy recovery system in this embodiment converts this energy into electrical energy, which is stored in the battery for use during vehicle acceleration or other power demands. A higher energy recovery level means the system recovers more energy from vehicle deceleration, resulting in faster deceleration. In congested urban traffic, frequent starts and stops may lead drivers to choose a lower energy recovery level to maintain a smooth driving experience; while on highways or in emergency situations, a higher energy recovery level may be preferred for faster deceleration.
[0042] In one embodiment of this application, the embodiment can identify the user's setting result for the energy recovery level; and determine the energy recovery level when the energy recovery system is started based on the setting result.
[0043] Specifically, users can preset their preferred energy recovery levels via the vehicle's central control screen or a dedicated application. These settings are stored in the vehicle's control system. This embodiment of the application determines the energy recovery level when the energy recovery system is activated by recognizing the settings. For example, if the user has a high need for deceleration, a higher energy recovery level can be set; conversely, if the user has a high need for coasting, a lower energy recovery level can be set. This allows the energy recovery level to be determined based on the user's needs, effectively improving the user experience.
[0044] It should be noted that if the user does not customize the settings, this application can adopt the factory default energy recovery level.
[0045] In step S102, the target lighting mode of the brake lights is determined based on the energy recovery level and the current driving scenario, and the target lighting parameters of the brake lights are determined based on the target lighting mode.
[0046] The lighting parameters for different lighting modes are different. The target lighting parameters include at least one of the lighting color, flashing frequency, and flashing interval duration. These parameters can be set according to the actual situation. For example, setting the lighting color to yellow has a high priority, while setting the lighting color to red has a low priority. The faster the flashing frequency, the higher the priority. Those skilled in the art can also set these parameters according to the actual situation without making specific limitations.
[0047] In one embodiment of this application, determining the target lighting mode of the brake light based on the energy recovery level and the current driving scenario includes: if the energy recovery level is less than a preset recovery level, then determining the target lighting mode of the brake light based on the current driving scenario; if the energy recovery level is greater than or equal to the preset recovery level, then determining the target lighting mode of the brake light based on the energy recovery level.
[0048] The preset safety level can be set in advance as needed, without specific restrictions. When the energy recovery level is lower than the preset level, this embodiment can determine how the brake lights should illuminate based on the current driving scenario. When the energy recovery level is greater than or equal to the preset level, the brake lights will be activated in a manner matching the energy recovery level. Therefore, this embodiment accurately determines the target illumination mode of the brake lights by comprehensively considering the impact of the energy recovery level and the current driving scenario on deceleration. This allows for accurate communication of the actual deceleration level to following vehicles, effectively improving the deceleration warning effect of the brake lights and ensuring driving safety.
[0049] For example, in this embodiment of the application, the preset safety level can be set to level 3 (out of a total of 5 levels), while the current energy recovery level is set to level 2. In this case, if the vehicle is driving smoothly on urban roads without significant deceleration, the brake light illumination will be determined based on the current driving scenario to determine the target illumination mode of the brake lights, such as based on traditional braking operations (e.g., whether the brake pedal is pressed).
[0050] If the current energy recovery level is set to level 4, which exceeds the preset value of level 3, it means that the vehicle is undergoing relatively strong energy recovery. The brake lights will illuminate in the manner corresponding to level 4, further enhancing the vehicle's driving safety.
[0051] Furthermore, in this embodiment of the application, the target lighting parameters of the brake lights can be determined according to the target lighting mode. For example, when driving on urban roads, there is a large volume of traffic and many pedestrians, and the traffic environment is complex, requiring frequent starts and stops. At this time, the energy recovery system is activated to decelerate, and the target lighting parameter is to keep the lights on in red until the accelerator is pressed again to accelerate, at which point the brake lights will turn off.
[0052] As one possible way to achieve this, such as Figure 2 As shown, when the highest level of energy recovery is used, the corresponding lighting parameters in this embodiment can be rapid flashing, uninterrupted, and the light color is yellow.
[0053] In one embodiment of this application, the target illumination mode of the brake light is determined according to the current driving scenario, and a first correspondence table between the driving scenario and the illumination mode is obtained; the target illumination mode corresponding to the current driving scenario is determined according to the first correspondence table.
[0054] In this embodiment, the first correspondence table between driving scenarios and illumination modes can be pre-calibrated. This first correspondence table is based on extensive experimental data and safety considerations, ensuring that the brake light illumination mode effectively alerts following vehicles under different driving conditions, preventing rear-end collisions and other traffic accidents. Once the current driving scenario is determined, this embodiment can accurately determine the target illumination mode matching the current driving scenario based on the first correspondence table.
[0055] In one embodiment of this application, the target lighting mode determined according to the first correspondence table is the first lighting mode. After determining the target lighting mode corresponding to the current driving scenario according to the first correspondence table, the method further includes: obtaining the current slope of the road where the vehicle is located; if the current slope is greater than the preset slope, then the target lighting mode is modified from the first lighting mode to the second lighting mode.
[0056] The preset slope can be set according to actual conditions and safety standards, and is used to determine whether the braking light illumination mode needs to be adjusted.
[0057] It is understood that the embodiments of this application can detect the road slope using sensors or by combining data from the positioning system and other sensors to calculate the current road slope. If the current slope is less than or equal to a preset slope, the target illumination mode of the brake lights in this embodiment will be determined according to the original logic based on the energy recovery level and the current driving scenario. If the current slope is greater than the preset slope, the embodiments of this application will modify the target illumination mode of the brake lights from the first illumination mode to the second illumination mode. The second illumination mode better reminds following vehicles to slow down, avoiding rear-end collisions caused by excessive speed due to a large slope. The second illumination mode has a higher safety level than the first illumination mode, for example, by activating the brake lights earlier, increasing brightness, or using a flashing mode, thereby better alerting following vehicles to the current vehicle status and improving road safety.
[0058] For example, such as Figure 3 As shown, if the current driving scenario determines the first illumination mode of the brake lights (the corresponding target illumination parameter can be a solid red light), and the vehicle enters a downhill section, under normal circumstances, releasing the accelerator activates the energy recovery system to convert excess kinetic energy generated by gravity into electrical energy. However, due to gravity, the vehicle may accelerate even without active braking. In this case, if the current slope is detected to be greater than a preset slope, the illumination mode of the brake lights in this embodiment needs to be corrected to the second illumination mode (the corresponding target illumination parameter can be a yellow light) until the vehicle leaves the section or accelerates again, at which point the brake lights turn off.
[0059] In one embodiment of this application, the target lighting mode determined according to the first correspondence table is the first lighting mode. After determining the target lighting mode corresponding to the current driving scenario according to the first correspondence table, the method further includes: obtaining the current rainfall of the environment in which the vehicle is located; if the current rainfall is greater than a first preset rainfall and less than or equal to a second preset rainfall, then the target lighting mode is modified from the first lighting mode to the third lighting mode; if the current rainfall is greater than the second preset rainfall, then the target lighting mode is modified from the first lighting mode to the fourth lighting mode.
[0060] It is understandable that roads are slippery and visibility is low in rainy weather. The amount of rainfall affects road surface slipperiness and driving visibility, with heavier rainfall generally having a greater impact. Therefore, in this embodiment, after the energy recovery system is activated in a rainy driving scenario, different lighting designs need to be implemented based on the rainfall value monitored by the rain sensor to better adapt to the impact of rainfall on the deceleration warning effect. The first preset rainfall can be set to 10 mm, and the second preset rainfall can be set to 25 mm. For example, if the cumulative rainfall in 24 hours is greater than 25 mm to 50 mm, or the hourly rainfall reaches 16 mm or more, the brake lights will flash rapidly and continuously, with a yellow light color. If the 24-hour rainfall reaches 10.0 mm to 25 mm, the brake lights will flash intermittently, with a yellow light color. The flashing frequency of the warning lights should ideally be high enough to attract attention without causing visual fatigue or misunderstanding. According to relevant research and standards, a flashing frequency of 1Hz (once per second) to 2Hz (twice per second) is appropriate for light warning signals. That is, each flash should last between 0.5 seconds and 1 second, which can effectively attract attention while ensuring the clarity of information transmission.
[0061] In actual implementation, the vehicle is first equipped with one or more rain sensors to detect the current rainfall. These sensors are typically installed in appropriate locations on the vehicle and can accurately measure the amount of precipitation per unit time. If the current rainfall is greater than a first preset rainfall and less than or equal to a second preset rainfall (i.e., 10.0 mm to 25 mm), this embodiment can modify the first illumination mode (the corresponding target illumination parameter can be a solid red light) to a third illumination mode (the corresponding target illumination parameter is that the brake lights will flash intermittently, and the light color is yellow). If the current rainfall is greater than the second preset rainfall, it indicates that the rainfall is very heavy. To further ensure vehicle safety, this embodiment can modify the first illumination mode (the corresponding target illumination parameter can be a solid red light) to a fourth illumination mode (the corresponding target illumination parameter is that the brake lights will flash rapidly without interruption, and the light color is yellow). In this way, even in special weather conditions, the lights can be illuminated in the most appropriate manner to enhance the alertness of vehicles behind, thereby improving road safety.
[0062] It should be noted that different regions or countries may have their own standards for classifying rainfall levels, and the classification should be based on local standards rather than being specifically limited.
[0063] In one embodiment of this application, determining the target lighting mode of the brake light based on the energy recovery level includes: obtaining a second correspondence table between the energy recovery level and the lighting mode; and determining the target lighting mode corresponding to the current energy recovery level based on the second correspondence table.
[0064] In this application embodiment, the second correspondence table between energy recovery level and illumination mode can be pre-calibrated. This second correspondence table is based on extensive experimental data and safety considerations, ensuring that the brake light illumination mode effectively alerts following vehicles under different driving conditions, preventing rear-end collisions and other traffic accidents. Once the energy recovery level is determined, this application embodiment can accurately determine the target illumination mode matching the energy recovery level based on the second correspondence table.
[0065] In step S103, the brake lights are controlled to illuminate according to the target illumination parameters.
[0066] It is understood that the embodiments of this application can control the illumination mode of the brake lights according to the illumination parameters determined above, so that the brake lights will illuminate in a specific way under specific conditions, thereby warning vehicles behind of the current vehicle status and improving driving safety.
[0067] Furthermore, after controlling the brake lights to illuminate according to the target illumination parameters, the method also includes generating a brake light illumination prompt.
[0068] In this embodiment, the control system needs to determine which type of prompt should be generated based on the specific mode of the brake light illumination (e.g., constant illumination, flashing, etc.). After the prompt information is generated, the control system will send it to the relevant display or prompt device of the vehicle so that the driver or other road users can receive this information. There are many ways to illuminate the prompt, such as sound alarm, visual indication on the dashboard, information notification on the in-vehicle display screen, etc.
[0069] In summary, the brake light illumination method of this application provides different illumination modes under different energy recovery levels and driving scenarios, making the brake light illumination more consistent with the current energy recovery level and driving scenario. This allows for accurate reminders of the actual deceleration level to following vehicles, effectively improving the deceleration warning effect of the brake lights, reducing the risk of rear-end collisions caused by speed changes due to energy recovery, and thus improving overall road traffic safety.
