Description

TECHNICAL FIELD

[0001] The present application relates to the field of intelligent control of vehicles, and in particular to a vehicle maintenance reminding method, device, equipment and storage medium. BACKGROUND

[0002] With the rapid development of intelligent technology of automobiles, the penetration rate in urban residents is close to 100%. Due to the high frequency of use of vehicles (such as daily commuting, travel, tourism, etc.), the running time is long, and various component wear and tear and potential safety hazards are easy to accumulate. Therefore, timely maintenance of the vehicle is particularly important. However, the main maintenance reminding methods on the market usually send maintenance reminders to users in the form of icons on the instrument panel, or push maintenance reminders to users through user mobile terminals, for example, when the vehicle travels to a set mileage, the corresponding maintenance reminder icon on the vehicle instrument panel lights up, prompting the user to maintain the vehicle. However, the above reminding methods have the problem that the maintenance reminding information is too general, and the maintenance reminding presentation method cannot really let the user understand the urgency of the vehicle maintenance needs, resulting in that the vehicle cannot be maintained in time, thereby affecting the service life of the vehicle and the driving safety of the vehicle.

[0067] To make the purpose, technical solutions and advantages of the present application clearer, the embodiments of the present application will be further described in detail below with reference to the drawings.

[0068] The present application provides a vehicle maintenance reminding method, as shown in the following formula (I): Figure 1 In some embodiments, the method is executed by a vehicle machine of the vehicle, and the vehicle machine is an in-vehicle infotainment device installed in the vehicle. As shown in the following formula (II): Figure 1 The vehicle machine includes a processor 110, a memory 120 and a communication component 130, etc., and each part will be described below:

[0069] The processor 110 can be a central processing unit (CPU), and the processor can be used to execute the vehicle maintenance reminding method described above.

[0070] The memory 120 can be various volatile memories or non-volatile memories, such as a solid state disk (SSD), a dynamic random access memory (DRAM) memory, etc. The memory can be used to store pre-stored data, intermediate data and result data in the processing process of the vehicle control.

[0071] The communication component 130 can be a wired network connector, a wireless fidelity (WiFi) module, a Bluetooth module, a cellular communication module, etc. The communication component can be used for data transmission with other devices.

[0072] The present application provides a vehicle maintenance reminding method, as shown in the following formula (I): Figure 2 In some embodiments, the method includes:

[0073] S101, based on the state information corresponding to at least one maintenance item of the vehicle, determining a target maintenance item of the vehicle that needs to be maintained.

[0074] In specific implementation, the maintenance items include, but are not limited to, oil and oil filter replacement, air filter replacement, fuel filter replacement, coolant replacement, air conditioning system inspection and maintenance, etc. The state information corresponding to the maintenance items includes at least one of the following: the driving time of the vehicle after the last maintenance on the maintenance item; and the driving mileage of the vehicle. By obtaining the driving time corresponding to each maintenance item in at least one maintenance item of the vehicle and the time threshold (the time threshold corresponding to each maintenance item is usually different, for example, the time threshold can be set to 12 months), the maintenance item corresponding to the driving time greater than or equal to the time threshold is determined as the target maintenance item in the at least one maintenance item. Or by obtaining the driving mileage corresponding to each maintenance item in at least one maintenance item of the vehicle and the mileage threshold (the mileage threshold corresponding to each maintenance item is usually different, for example, the mileage threshold can be set to 5000 kilometers), the maintenance item corresponding to the driving mileage greater than or equal to the mileage threshold is determined as the target maintenance item in the at least one maintenance item.

[0075] In S102, a target prompt level of the target maintenance item is determined based on the state information corresponding to the target maintenance item.

[0076] In specific implementation, when the state information corresponding to the maintenance item includes the driving time of the vehicle, first, a first difference between the driving time corresponding to the target maintenance item and the time threshold corresponding to the target maintenance item is determined, the first difference ΔT=T1-T0, wherein T1 represents the driving time corresponding to the target maintenance item, and T0 represents the time threshold corresponding to the target maintenance item. Then, the target prompt level of the target maintenance item is determined based on the first difference. Generally, the greater the first difference, the higher the target prompt level of the target maintenance item (the higher the target prompt level indicates the higher the urgency of the maintenance of the target maintenance item), that is, the target prompt level is positively correlated with the first difference. The correspondence between the first difference and the target prompt level can be established, as shown in Table 1:

[0077] Table 1

[0078] First difference (unit: day) Target prompting level 10 1 20 2 30 3

[0079] Table 1 is used to illustrate the target prompt level corresponding to the first difference. In actual operation, the technician can set the correspondence between the first difference and the target prompt level according to the actual situation.

[0080] When the status information corresponding to the maintenance item includes the vehicle's mileage, a second difference between the mileage corresponding to the target maintenance item and the mileage threshold corresponding to the target maintenance item is first determined. The second difference ΔL = L1 - L0, where L1 represents the mileage corresponding to the target maintenance item and L0 represents the mileage threshold corresponding to the target maintenance item. A target prompt level for the target maintenance item is then determined based on the second difference. Generally, the larger the second difference, the higher the target prompt level for the target maintenance item (a higher target prompt level indicates a greater degree of maintenance urgency for the target maintenance item), i.e., the target prompt level is positively correlated with the second difference. A corresponding relationship between the second difference and the target prompt level can be established, as shown in Table 2:

[0081] Table 2

[0082] Second difference (unit: km) Target prompting level 100 1 200 2 300 3

[0083] Table 2 is used to illustrate the target prompt level corresponding to the second difference. In actual operation, technicians can set the corresponding relationship between the second difference and the target prompt level according to actual conditions.

[0084] S103: Issue maintenance reminder information based on the target maintenance item and the target reminder level.

[0085] During specific implementation, the corresponding maintenance reminder information can be determined based on the target maintenance items. The maintenance reminder information usually includes but is not limited to the next maintenance time or the remaining available mileage (for example: "The next maintenance must be completed in 30 days or within 5,000 kilometers"); or lists the target maintenance parts (such as "Replace the oil filter" and "Test the brake fluid"); or informs the time required for maintenance (such as "This maintenance will take about 1.5 hours"). At the same time, the reminder frequency of the maintenance reminder information can be determined based on the target reminder level. The higher the target reminder level, the higher the reminder frequency, that is, the reminder frequency is positively correlated with the target reminder level. The corresponding relationship between the target reminder level and the reminder frequency can be established, as shown in Table 3:

[0086] Table 3

[0087] Target prompting level Prompting frequency 1 Once every 60 minutes 2 Once every 30 minutes 3 Once every 5 minutes

[0088] Table 3 is used to illustrate the prompt frequency corresponding to the target prompt level. In actual operation, technicians can set the corresponding relationship between the target prompt level and the prompt frequency according to actual conditions.

[0089] After the reminder frequency is determined, the maintenance reminder information is sent based on the reminder frequency. The reminder period can be controlled by an onboard timer. The higher the target reminder level, the shorter the timer triggering interval.

[0090] In this embodiment, the user can clearly understand which specific items of the vehicle require maintenance, as well as the urgency of the maintenance. For example, by clearly prompting "The engine oil life is less than 10%, it is recommended to replace it immediately", the user can clearly know where the problem lies, instead of the traditional reminder that only knows that the vehicle needs maintenance, but is unclear about where specifically maintenance is needed. Different prompt frequencies can allow users to intuitively feel the urgency of maintenance. When the target prompt level is higher and the prompt frequency increases, the user will realize the seriousness of the problem and take action more promptly. Users can reasonably arrange maintenance time according to the suggestions in the maintenance prompt information to avoid vehicle failures due to untimely maintenance, help users discover potential hidden troubles in the early stages of the problem, and reduce the failure rate of the vehicle.

[0091] In some embodiments, the maintenance reminder information includes visual reminder information; and issuing the maintenance reminder information based on the reminder frequency includes: displaying the visual reminder information based on the reminder frequency.

[0092] In specific implementations, visual prompts include but are not limited to icon prompts, such as a yellow oil can icon, which indicates that the oil life is low or needs to be replaced. It can also be directly prompted by text, such as "Maintenance now" or "Please change the oil." Displaying visual prompts based on the prompt frequency can convey the urgency of vehicle maintenance to the user, such as once every 30 minutes. Visual prompts can be displayed on the instrument panel or projected onto the windshield through a head-up display (HUD). The driver can receive prompts without looking down, which is particularly suitable for scenarios that require concentration, such as high-speed driving. In addition, visual prompts can be displayed on the user's mobile terminal.

[0093] Optionally, the maintenance reminder information includes audio reminder information; and sending the maintenance reminder information based on the reminder frequency includes: playing the audio reminder information based on the reminder frequency.

[0094] In specific implementations, audio prompt information includes but is not limited to basic beeps, such as a single short beep, which can be used for prompts with a low frequency, such as once every 30 minutes, with a volume of about 60dB; or a cyclic beep, which can be used for prompts with a high frequency, such as once every 2 minutes, to enhance the sense of urgency and increase the volume to above 75dB. Audio prompt information can also include voice broadcasts to clearly announce specific maintenance items and risks (such as "Please change the engine oil immediately, the remaining life is less than 10%) to avoid users confusing the meaning of icons.

[0095] In addition, the maintenance reminder information is issued based on the reminder frequency, the visual reminder information can be displayed based on the reminder frequency, and the audio reminder information can be played based on the reminder frequency, so as to achieve the effect of strengthening the maintenance reminder.

[0096] In this embodiment, the user can intuitively see the vehicle maintenance needs through visual prompt information. Visual prompts are particularly suitable for use during driving, as the user can quickly obtain information through the dashboard or a heads-up display system without having to look away to check other devices. Audio prompt information can also ensure that the user can obtain information without having to look away to check other devices. Adjusting the prompt frequency according to the target prompt level can more accurately convey the urgency of maintenance, effectively avoiding the user's neglect of the maintenance prompt information, and ensuring that the user takes timely action. When visual and audio prompts are used simultaneously, the prompting effect on the user can be enhanced. Through multi-dimensional prompting methods, the user can discover potential problems in the vehicle and perform maintenance in a timely manner, thereby reducing the failure rate of the vehicle. Accurate maintenance reminders can avoid over-maintenance and reduce unnecessary maintenance costs, and timely maintenance can extend the service life of vehicle components and reduce the cost of major repairs due to component damage.

[0097] Since the visual prompt for traditional vehicle maintenance is prone to being ignored. To solve this problem, a dynamic brightness adjustment mechanism is added, which forcibly enhances the warning effect by increasing the display brightness when the user does not respond to the prompt within a preset display duration, thereby avoiding delays in maintenance tasks due to environmental light interference or user distraction. Therefore, in some embodiments, after displaying the visual prompt information based on the prompt frequency, the method further comprises:

[0098] determining a display duration for displaying the visual prompt information based on the prompt frequency; and in response to the display duration being greater than or equal to a preset display duration, increasing the display brightness of the visual prompt information.

[0099] In specific implementation, when the display duration is greater than or equal to a preset display duration (for example, the preset display duration can be set to 60 minutes), there may be a problem of visual prompt information being ignored due to environmental light interference or user distraction, at which time increasing the display brightness of the visual prompt information can control the brightness by adjusting the pulse duty cycle of the backlight LED (light-emitting diode), for example, the duty cycle is increased from 30% to 60%, and the corresponding brightness is increased from 100 cd / ㎡ to 200 cd / ㎡.

[0100] After playing the audio prompt information based on the prompt frequency, the method further comprises:

[0101] determining a play duration for playing the audio prompt information based on the prompt frequency; and in response to the play duration being greater than or equal to a preset play duration, increasing the volume of the audio prompt information.

[0102] In specific implementation, when the playback duration is greater than or equal to the preset playback duration, there may be a problem that the ambient noise is loud and the user cannot hear the audio prompt information, which causes the user to fail to respond to the vehicle maintenance prompt information for a long time. Therefore, the volume of the audio prompt information is increased. For example, the volume is gradually increased from 60dB to 85dB to cover noisy environments such as high-speed driving.

[0103] In this embodiment, by increasing the display brightness when the user does not respond to the prompt, the interference of ambient light can be effectively overcome, ensuring that the visual prompt information is clearly visible under any lighting conditions. For example, in a strong light environment (such as direct sunlight), the initial brightness may not be enough to attract the user's attention, but by increasing the brightness from 100cd / ㎡ to 200cd / ㎡, the prominence of the prompt can be significantly enhanced, ensuring that the user can notice the maintenance prompt. Users may be distracted for various reasons while driving, such as checking the navigation, answering the phone, etc. By dynamically increasing the brightness, the user's attention can be re-attracted to avoid missing maintenance prompts due to distraction. In a noisy environment (such as wind noise, engine noise when driving at high speed, etc.), the initial volume may not be enough for the user to hear the prompt information. By gradually increasing the volume, for example, from 60dB to 85dB, it can be ensured that the audio prompt information can penetrate the ambient noise and be clearly heard by the user.

[0104] In some embodiments, the vehicle includes a head-up display system; and displaying the visual prompt information based on the prompt frequency includes:

[0105] The head-up display system is controlled to display the visual prompt information at the prompt frequency.

[0106] In specific implementations, a HUD uses optical projection technology to project key driving information (such as vehicle speed, navigation, and warning alerts) onto a transparent medium (windshield or specialized resin panel) in the user's field of view. Its core goal is to reduce visual deviation and improve driving safety. Therefore, the head-up display system is controlled to display the visual prompt information at a specified prompt frequency, allowing the driver to receive prompts without lowering their head. Furthermore, compared to the instrument panel, the HUD can display more detailed information, such as vehicle maintenance parts, maintenance procedures, and navigation information to the nearest maintenance site. Users can perform maintenance according to the maintenance procedures or use navigation information to find the nearest maintenance site.

[0107] This embodiment is achieved by Figure 3The process of how to control the head-up display system to display the visual prompt information is described in detail: the user can operate the central control screen to determine whether to start the vehicle maintenance reminder function, when the user selects to start, the vehicle machine obtains at least one state information corresponding to the maintenance item through the vehicle sensor, and determines the target maintenance item of the vehicle that needs to be maintained; based on the state information corresponding to the target maintenance item, the target prompt level of the target maintenance item is determined; and the HUD light machine control system determines the visual prompt information based on the target maintenance item and the target prompt level, and controls the HUD light machine to project the visual prompt information on the front windshield.

[0108] In this embodiment, the core advantage of the HUD is to project key information onto a transparent medium in front of the user's field of view, allowing the user to obtain information without having to look down at the instrument panel or other devices. In the vehicle maintenance reminder scenario, the maintenance prompt information is displayed through the HUD, and the user can keep their eyes on the road, reducing the deviation of the line of sight caused by viewing information, thereby reducing the risk of driving. For example, when driving at high speed, the user may need a few seconds to look down at the instrument panel, and in this period of time, the vehicle may have traveled tens of meters or even hundreds of meters, which poses a high safety hazard. By displaying the maintenance prompt information through the HUD, the user can obtain the information without leaving the line of sight of the road, significantly improving driving safety. The HUD can display visual prompt information at a high prompt frequency to ensure that the user can promptly pay attention to the maintenance prompt. For example, when the prompt frequency is once every 30 minutes, the user can see the maintenance prompt multiple times in a short time interval, thereby responding more quickly to the maintenance needs. Through the dynamic brightness adjustment mechanism, the HUD can automatically increase the display brightness when the user does not respond to the prompt, further ensuring that the user can pay attention to the prompt information and avoiding delays in maintenance tasks due to environmental light interference or user distraction. The HUD can not only display simple icon or text prompts, but also display more detailed information, such as the maintenance components of the vehicle, the maintenance process, and the navigation information of the nearest maintenance location. This detailed information display method can help the user better understand the vehicle's maintenance needs, thereby making more informed decisions. For example, the HUD can display specific prompts such as "engine oil life is less than 10%, please replace immediately" and "please check the brake pad wear condition", and can also display detailed steps such as "maintenance process: 1. Park and turn off the engine; 2. Open the engine compartment cover; 3. Replace the engine oil filter" to help the user perform simple maintenance operations. In addition, the HUD can also display navigation information of the nearest maintenance location, such as "the nearest 4S store is 10 kilometers away from you, and the estimated driving time is 15 minutes", to facilitate the user to go to the maintenance location for maintenance.

[0109] Since the traditional vehicle maintenance prompt system has the problem that single-mode prompts are easily ignored, the maintenance prompt effect can be gradually strengthened by switching the prompt mode according to the user response delay. Therefore, in some embodiments, the maintenance prompt information includes visual prompt information and audio prompt information; the maintenance prompt information is issued based on the prompt frequency, including:

[0110] The visual prompt information is displayed based on the prompt frequency, and in response to the display duration of the visual prompt information being greater than or equal to a preset display duration, the audio prompt information is played based on the prompt frequency.

[0111] In specific implementation, a visual warning icon can be displayed on the instrument panel or HUD based on the prompt frequency (such as once every 15 minutes), and if the display duration is greater than or equal to a preset display duration (for example, the preset display duration can be set to 60 minutes) without user operation (such as clicking to confirm), an audio prompt (such as a beeping sound or voice broadcast) is activated.

[0112] The audio prompt information is played based on the prompt frequency, and in response to the play duration of the audio prompt information being greater than or equal to a preset play duration, the visual prompt information is displayed based on the prompt frequency.

[0113] In specific implementation, a short beeping sound can be played based on the prompt frequency (such as a single 0.5 second, once every 20 minutes), and if the play duration of the audio prompt information is greater than or equal to a preset play duration (for example, the preset play duration can be set to 30 minutes) without response, the visual prompt (such as a red wrench icon projected by the HUD + pulsing flashing animation) is activated, and its display brightness can be adapted to the ambient light (such as increased to 300 cd / m2 in strong light).

[0114] In this embodiment, for the switching from visual prompt to audio prompt, the user is first reminded through visual prompt (such as icon on instrument panel or HUD) at a certain frequency. If the user does not respond within the preset display duration, switch to audio prompt. This gradual prompting from visual to audio can gradually increase the urgency of the prompt, ensuring that the user will not ignore the maintenance prompt. For the switching from audio prompt to visual prompt, if the user still does not respond to the audio prompt within the preset play duration, switch to visual prompt. Different users have different sensitivities to visual and audio prompts. Some users may be more likely to notice visual prompts, while some users may be more sensitive to audio prompts. Multi-modal prompts can dynamically adjust the prompt mode according to the user's response, ensuring that all users can receive and notice the maintenance prompt in time.

[0115] In some embodiments, the state information corresponding to the maintenance item includes a tread depth of a tire of the vehicle; and determining the target maintenance item of the vehicle based on the state information corresponding to the at least one maintenance item of the vehicle includes: obtaining the tread depth of the tire of the vehicle corresponding to the tire maintenance item and a depth threshold value; and determining the tire maintenance item as the target maintenance item in response to the tread depth being less than or equal to the depth threshold value.

[0116] In specific implementation, the tread depth of the tire of the vehicle can be obtained by a 360-degree panoramic image system. Since the 360-degree panoramic image system mainly captures images through cameras around the vehicle, during turning of the vehicle, part of the front tire of the vehicle will be out of the range of the vehicle body. At this time, the 360-degree panoramic image system can capture images of the tire of the vehicle (in addition, a camera or an ultrasonic sensor can be arranged at a specific position of the vehicle to capture images of the tire of the vehicle). Then, the image recognition algorithm is used to detect and identify the images of the tire of the vehicle to obtain the tread depth of the tire of the vehicle. The tread depth of the tire of the vehicle corresponding to the tire maintenance item and a depth threshold value (the depth threshold value corresponding to different types of vehicles is usually different. For example, the depth threshold value of a sedan can be set to 3.5 mm, and the depth threshold value of a sport utility vehicle can be set to 5 mm) are determined. When the tread depth is less than or equal to the depth threshold value, the tire maintenance item is determined as the target maintenance item.

[0117] The target prompt level of the target maintenance item is determined based on the state information corresponding to the target maintenance item, which includes: determining a third difference between the tread depth of the tire of the vehicle and the depth threshold value; determining the target prompt level of the tire maintenance item based on the third difference, wherein the target prompt level is positively correlated with the third difference.

[0118] In specific implementation, when the state information corresponding to the maintenance item includes the tread depth of the tire of the vehicle, first, a third difference between the tread depth of the tire of the vehicle and the depth threshold value is determined, and the third difference AS = |S1-S0|, wherein S1 represents the tread depth, and S0 represents the depth threshold value. Then, the target prompt level of the tire maintenance item is determined based on the third difference. Generally, the larger the third difference, the higher the target prompt level of the target maintenance item (the higher the target prompt level indicates that the maintenance urgency of the target maintenance item is higher). That is, the target prompt level is positively correlated with the third difference. The corresponding relationship between the third difference and the target prompt level can be established, as shown in Table 4.

[0119] Table 4

[0120] Third difference (unit: mm) Target prompting level 0.5 1 1.0 2 1.5 3

[0121] Table 4 is used to illustrate the target prompt level corresponding to the third difference. In actual operation, the technical personnel can set the correspondence between the third difference and the target prompt level according to the actual situation.

[0122] In this embodiment, the tire image is collected by a 360-degree panoramic image system or a camera at a specific position and an ultrasonic sensor, and the image recognition algorithm is used to detect the tire pattern depth, so that the actual wear condition of the tire can be accurately determined. When the pattern depth is less than or equal to the depth threshold, the tire maintenance item is determined as the target maintenance item, and the user is reminded to check or replace the tire in time. The tire pattern depth is a key factor affecting the tire grip and drainage performance. When the pattern depth is too low, the tire grip will decrease significantly, especially on wet road surface, which can easily lead to increased braking distance, vehicle out of control and other dangerous situations. By reminding the user to replace the severely worn tire in time, traffic accidents caused by tire problems can be effectively prevented. Since the user does not need to manually check the tire pattern depth, the user's operation burden is reduced.
