[0068] The following describes the present application based on embodiments, but the present application is not limited to these embodiments. In the following detailed description of the present application, some specific details are described in detail. Those skilled in the art can fully understand the present application without the description of these detail parts. In order to avoid obscuring the essence of the present application, well-known methods, processes, procedures, elements, and circuits are not described in detail.

[0069] In addition, those of ordinary skill in the art should understand that the accompanying drawings provided herein are for illustrative purposes only, and the drawings are not necessarily drawn to scale.

[0070] Unless the context clearly requires otherwise, words such as "including" and "comprising" in the entire application document should be interpreted as having an inclusive meaning rather than an exclusive or exhaustive meaning; that is, it is the meaning of "including but not limited to".

[0071] In the description of the present application, it should be understood that terms such as "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance. In addition, in the description of the present application, unless otherwise specified, the meaning of "a plurality of" is two or more.

[0072] In the solutions described in this specification and the embodiments, if personal information processing is involved, it will be processed on the premise of having a legal basis (such as obtaining the consent of the personal information subject, or being necessary for performing a contract, etc.), and will only be processed within the specified or agreed scope. If a user refuses to process personal information other than the necessary information required for basic functions, it will not affect the user's use of basic functions.

[0073] Figure 1 is a schematic diagram of a vehicle braking information interaction system according to an embodiment of the present invention. As Figure 1 shown, the vehicle braking information interaction system includes a server 10 and a vehicle 11 connected through a network. During the process of a user using the vehicle, the vehicle 11 collects the vehicle position and the vehicle driving direction and sends them to the server 10. After receiving the vehicle position and the vehicle driving direction sent by the vehicle 11, the server 10 determines the target warning position information according to the vehicle position and the vehicle driving direction, and further determines the available resource amount based on the vehicle position and the target warning position. The server 10 sends the determined target warning position information and the available resource amount to the corresponding vehicle 11. The vehicle 11 receives the target warning position information and the available resource amount, and continuously updates the available resource amount according to the vehicle driving state. When the available resource amount reaches a predetermined threshold, the vehicle 11 controls the vehicle to brake. In this embodiment, the server 10 is a general processing device that can run an application program to execute data processing functions. It can be an independently set server, a set of servers arranged in a cluster manner, or a cloud server using cloud technology.

[0074] Figure 2 is a flowchart of a vehicle braking method according to an embodiment of the present invention. The vehicle can be a vehicle of categories such as an electric vehicle or a bicycle. This embodiment mainly takes the vehicle category as an electric vehicle for illustration. The vehicle braking method of this embodiment can be applied to a vehicle terminal, where the vehicle terminal can be a central control device in the vehicle or a general data processing terminal that is separately set and can run a computer program and has a communication function. This embodiment does not limit this. As Figure 2 shown, the vehicle braking method according to an embodiment of the present invention includes the following steps:

[0075] Step S210, receiving the target warning position information and the available resource amount.

[0076] Specifically, the vehicle terminal receives the target warning position and available resource quantity information sent by the server. Among them, the target warning position information includes the target warning position, which is determined according to the vehicle position and the vehicle driving direction. The target warning position is the warning position closest to the current vehicle position in the vehicle's forward direction. The warning position refers to an area where the vehicle often needs to stop or slow down and avoid during driving, such as intersections, school gates, road construction sites, and other areas. In some implementation manners, the vehicle obtains the vehicle position and the vehicle driving direction and uploads them to the server. The server determines the target warning position according to the warning position information database, the vehicle position, and the vehicle driving direction and sends it to the vehicle. Multiple warning position information determined according to historical data is stored in the warning position information database. Optionally, the vehicle can obtain the vehicle position and the vehicle driving direction through the vehicle terminal installed on the vehicle and upload them to the server, and receive the target warning position information and the initial value of the available resource quantity sent by the server. For example, a positioning device and a gyroscope communicable with the vehicle terminal can also be set on the vehicle to collect the vehicle position and the vehicle driving direction and send the vehicle position and the vehicle driving direction to the vehicle terminal. Optionally, the vehicle terminal can be communicably connected to the positioning device and the gyroscope by wired or wireless means.

[0077] In some implementation manners, the available resource quantity characterizes the distance from the vehicle position to the target warning position or the time required to travel from the vehicle position to the target warning position.

[0078] Step S220, continuously update the available resource quantity according to the vehicle driving state.

[0079] In some implementation manners, when the available resource quantity characterizes the distance from the vehicle position to the target warning position, during the vehicle driving process, the vehicle terminal updates the distance from the vehicle position to the target warning position according to the latest obtained vehicle position and the target warning position, so as to control the vehicle braking when the distance is updated to a predetermined threshold.

[0080] In some other implementation manners, when the available resource quantity characterizes the time required to travel from the vehicle position to the target warning position, during the vehicle driving process, after determining the time required to travel from the vehicle position to the target warning position, the vehicle terminal controls a timing device, such as a timer, to continuously time, so as to update the time required to travel from the vehicle position to the target warning position. As long as the latest obtained vehicle driving direction does not indicate a change in the vehicle driving direction, it indicates that the target warning position that the vehicle may pass through has not changed. At this time, by continuously updating the timing value in the timer, the vehicle braking can be controlled when the required time is updated to a predetermined threshold. Among them, the timer can time the time required to travel from the vehicle position to the target warning position in a countdown manner.

[0081] Further, in response to a change in the vehicle driving direction, the update of the available resource amount is stopped.

[0082] When the vehicle driving direction changes, it indicates that the target warning position passed by the vehicle may change, that is, the vehicle may not pass through the currently determined target warning position. At this time, the vehicle can stop updating the available resource amount. Correspondingly, the server will re-determine the new target warning position and the available resource amount according to the vehicle position and the vehicle driving direction, and send them to the vehicle terminal. That is, when the vehicle driving direction changes, this embodiment returns to execute step S210.

[0083] In some embodiments, since updating the distance from the vehicle position to the target warning position needs to be achieved by continuously collecting and updating the vehicle position. And when calculating the time required to drive from the updated vehicle position to the target warning position, only obtain the vehicle position once and calculate the initial required time, and then the timing device can automatically update the timing to achieve it. Therefore, in the actual application scenario, it is possible to preferentially select to update the available resource amount corresponding to the time required to drive from the vehicle position to the target warning position.

[0084] Step S230, in response to the available resource amount reaching a predetermined threshold, control the vehicle to brake.

[0085] In some embodiments, when the distance from the vehicle position to the target warning position reaches a predetermined threshold, the vehicle terminal controls the vehicle to brake. The predetermined threshold can be set to 0 meters. That is, when the vehicle drives to the target warning position, the vehicle terminal controls the vehicle to brake, or the predetermined threshold can also be set to 10 meters, that is, when the vehicle has not yet driven to the target warning position, the vehicle is controlled to brake in advance.

[0086] In some other implementation manners, when the time required to drive from the vehicle position to the target warning position reaches a predetermined threshold, control the vehicle to brake. The predetermined threshold can be set to 0 seconds, that is, when the vehicle drives to the target warning position, control the vehicle to brake, or the predetermined threshold can also be set to 3 seconds, that is, when the vehicle has not yet driven to the target warning position, the vehicle is controlled to start braking in advance.

[0087] It should be understood that in the actual application scenario, the specific predetermined threshold can be set according to actual needs, and this embodiment does not limit this.

[0088] In some embodiments, the target warning position information further includes a warning level. Further, the predetermined threshold can be determined according to the warning level to control the vehicle to brake when the available resource amount reaches the predetermined threshold.

[0089] In some implementations, the warning level can be determined based on the deceleration amplitude of historical vehicles. Specifically, in this embodiment, the deceleration amplitude of historical vehicles at the warning position is collected, and the average deceleration amplitude of the vehicle at the corresponding position is calculated. The warning level corresponding to the warning position is determined based on the average deceleration amplitude. The greater the average deceleration amplitude, the higher the warning level. It should be understood that each warning level corresponds to a range of deceleration amplitudes. In some implementations, the highest warning level can be determined as level one, and the lowest warning level can be determined as level three. It should be understood that in actual application scenarios, the division method of the warning level and the number of warning levels can be determined according to actual needs, and this embodiment does not limit this.

[0090] Specifically, at the warning position with a high warning level, a large predetermined threshold is set so that when the warning level of the target warning position is higher, the vehicle braking is controlled earlier, thereby ensuring that the vehicle can brake in time. For example, when the available resource amount represents the time required for the vehicle to travel to the target warning position, the predetermined threshold corresponding to the warning position with a warning level of level one can be set to 2 seconds, the predetermined threshold corresponding to the warning position with a warning level of level two can be set to 1 second, and the predetermined threshold corresponding to the warning position with a warning level of level three can be set to 0 seconds. It should be understood that the predetermined thresholds corresponding to the warning positions of each warning level can be set according to actual situations, and this embodiment does not limit this.

[0091] In some implementations, the deceleration amplitude can be determined based on the warning level, and the vehicle braking can be controlled according to the deceleration amplitude.

[0092] Specifically, the higher the warning level of the warning position, the greater the set deceleration amplitude, so that when the warning level of the target warning position is higher, the vehicle can complete braking in a shorter time, thereby ensuring that the vehicle can brake in time and avoiding traffic accidents. The specific deceleration amplitudes corresponding to the warning positions of each warning level can be set according to actual situations, and this embodiment does not limit this.

[0093] When controlling the vehicle braking, this embodiment can directly control the braking system to brake the vehicle, or can control the vehicle to cut off power, thereby controlling the vehicle braking.

[0094] In some embodiments, in response to the vehicle accelerating again, the braking of the vehicle is suspended. Specifically, during the process of controlling the vehicle to brake, if the user confirms that the current road condition is safe and there is no need to decelerate, the user can accelerate again by stepping on the accelerator pedal or other means. After the vehicle senses that the user accelerates again, the braking of the vehicle at the current target warning position is suspended, and the vehicle passes through the current target warning position at the corresponding speed according to the user's control.

[0095] In an embodiment of the present invention, by receiving target warning position information and available resources, the available resources are continuously updated according to the vehicle driving state, and in response to the available resources reaching a predetermined threshold, the vehicle is controlled to brake. Wherein, the target warning position information includes a target warning position, the target warning position is determined according to the vehicle position and the vehicle driving direction, and the available resources represent the distance from the vehicle position to the target warning position or the time required to drive from the vehicle position to the target warning position. Thus, it is realized to control the vehicle to brake when the vehicle reaches the target warning position, thereby avoiding traffic accidents caused by brake failure.

[0096] Figure 3 It is a flowchart of a vehicle data processing method according to an embodiment of the present invention. The method of this embodiment can be applied to the server side. As Figure 3 shown, the vehicle data processing method according to an embodiment of the present invention includes the following steps:

[0097] Step S310, obtain the vehicle position and the vehicle driving direction.

[0098] Specifically, in this embodiment, the vehicle position and the vehicle driving direction can be periodically collected by motion sensors such as a positioning device and a gyroscope provided on the vehicle, and uploaded to the server through the vehicle terminal, so that the server can correspondingly obtain the vehicle position and the vehicle driving direction.

[0099] Step S320, determine the target warning position information according to the vehicle position and the vehicle driving direction.

[0100] Wherein, the target warning position information includes a target warning position. The steps of determining the target warning position information in this embodiment are as Figure 4 shown, and specifically include:

[0101] Step S410, based on the vehicle position, determine the screening range of warning position information.

[0102] Specifically, the screening range of warning position information can be a circular range centered on the currently obtained vehicle position with a preset length as the radius. The value of the preset length can be set according to actual needs, and this embodiment does not limit this.

[0103] Step S420, determine the candidate warning position information according to the screening range of warning position information and the warning position information library.

[0104] Wherein, the generation steps of the warning position information library in this embodiment are as Figure 5 shown, and specifically include:

[0105] Step S510, obtain the time period, position and vehicle deceleration amplitude when the historical vehicle starts the manual brake system.

[0106] Step S520: Determine the warning positions corresponding to the time period as the positions where the frequency of starting the manual braking system is greater than a preset value.

[0107] Among them, the time period is a time period divided according to time characteristics. In some implementation manners, the time period can be divided with a day as the division object. For example, the time of a day can be evenly divided into four time periods: 00:00 - 5:59, 6:00 - 11:59, 12:00 - 17:59, and 18:00 - 23:59. Or, the time of a day can be divided into two types of time periods: peak periods and non-peak periods. Since the climate in different seasons has a great impact on road conditions, for example, some sections are prone to icing in winter, resulting in the need to brake at corresponding positions. Therefore, in some implementation manners, the time period can also be divided according to different seasons. For example, a year can be divided into four quarters: January - March, April - June, July - September, and October - December to determine four different time periods. In some implementation manners, the season can also be used as the first dimension and the time period in a day as the second dimension to divide the time period. It should be understood that the division method of the time period can be determined according to actual needs, and this embodiment does not limit this.

[0108] If the number of times of starting the manual brake at a certain position of the vehicle in a certain time period is greater than a preset value (for example, 50 times), it indicates that the probability of braking at this position is very high, and this position is determined as the warning position corresponding to the corresponding time period. Thus, this embodiment can determine all positions where the frequency of starting the manual braking system is greater than the preset value and determine them as the warning positions corresponding to the corresponding time period.

[0109] Step S530: Determine the warning level of the warning position according to the vehicle deceleration amplitude to determine the warning position information.

[0110] Specifically, the greater the vehicle deceleration amplitude, the higher the warning level of the corresponding warning position. This embodiment determines the warning position information based on the warning position and the warning level of the warning position.

[0111] Step S540: Generate the warning position information library based on the warning position information.

[0112] This embodiment stores all the determined warning position information in the corresponding storage location to generate a warning position information library. The warning position information library can be continuously updated as the vehicle driving data is updated during the vehicle operation process.

[0113] Furthermore, after determining the warning position information screening range and the corresponding time period, since each warning position in the current warning position information library is relatively determined, the warning positions in the warning position information screening range in the warning position information library, that is, the candidate warning positions, can be determined.

[0114] In some embodiments, the warning position information can also be directly determined based on existing map navigation software. After determining the screening range of the warning position information and the corresponding time period, the candidate warning positions are determined by identifying the warning positions within the screening range of the warning position information in the map navigation software.

[0115] Step S430: Determine the target warning position information based on the candidate warning position information and the vehicle driving direction.

[0116] The server determines the candidate warning position information that is in the vehicle's forward direction and closest to the vehicle position according to the vehicle driving direction, and determines it as the target warning position.

[0117] Step S330: Determine the available resource quantity based on the vehicle position and the target warning position.

[0118] Wherein, the available resource quantity represents the distance from the vehicle position to the target warning position or the time required to travel from the vehicle position to the target warning position.

[0119] In some implementation manners, the available resource quantity represents the distance from the vehicle position to the target warning position. The server calculates the distance from the vehicle position to the target warning position based on the acquired vehicle position and the target warning position, so as to determine the available resource quantity.

[0120] In some other implementation manners, the available resource quantity represents the time required to travel from the vehicle position to the target warning position. After the server calculates the distance from the vehicle position to the target warning position based on the acquired vehicle position and the target warning position, it then calculates the time required for the vehicle to travel to the target warning position according to the average speed of the vehicle and the distance from the vehicle position to the target warning position, so as to determine the available resource quantity. Wherein, the average speed of the vehicle can be the average driving speed corresponding to the road section where the vehicle is located, or the average speed of the vehicle from the start of the current driving to the current time.

[0121] Step S340: Send the target warning position information and the available resource quantity to the corresponding vehicle.

[0122] The server sends the target warning position information and the available resource quantity to the corresponding vehicle, so that the corresponding vehicle can determine the updated status of the available resource quantity based on the target warning position information, the vehicle position, and the vehicle driving direction, and then control the vehicle to brake when the available resource quantity reaches a predetermined threshold.

[0123] In some embodiments, the process of controlling the vehicle braking can be initiated throughout the entire current driving. In other embodiments, the process of controlling the vehicle braking can be initiated without confirming whether the manual braking system is normal, and after confirming that the manual braking system is normal, the process of controlling the vehicle braking is stopped during the current driving. Thus, in this embodiment, by controlling the vehicle braking, the vehicle can be braked in time in the case of a malfunction of the manual braking system, avoiding traffic accidents.

[0124] In some embodiments, subsequent vehicle use services are provided to the user based on the state of the vehicle's manual braking system. As Figure 6 shown, the specific steps include:

[0125] Step S610, obtaining the startup state of the manual braking system.

[0126] In some embodiments, a braking monitoring device communicable with the vehicle terminal can be provided on the vehicle. Through the braking monitoring device, the state of the manual braking system can be monitored, so that the vehicle can obtain the state of the manual braking system through the vehicle terminal installed on the vehicle and upload it to the server. If the braking monitoring device monitors that the user presses the manual braking system continuously for multiple times or the pressing time of the manual braking system exceeds the preset pressing time (for example, 1 second), it indicates that the user has actively started the manual braking system. Optionally, the vehicle terminal can be communicably connected to the braking monitoring device by wire or wirelessly.

[0127] Step S620, in response to the manual braking system being started and the vehicle deceleration amplitude remaining unchanged, determining that the manual braking system is in a faulty state.

[0128] It is not difficult to understand that when the manual braking is normal, after the user starts the manual braking system for the first time, the vehicle deceleration amplitude should be the superposition of the deceleration amplitude of controlling the vehicle to automatically brake based on the process of controlling the vehicle braking and the deceleration amplitude of the manual braking system. Therefore, the deceleration amplitude of the vehicle should increase. If the vehicle deceleration amplitude remains unchanged, it indicates that the manual braking system is in a faulty state.

[0129] Step S630, in response to the manual braking system being in a faulty state, sending a fault prompt message.

[0130] When the manual braking system is in a faulty state, the server sends a fault prompt message to the corresponding display device to prompt the user that the current vehicle has a fault and confirm with the user whether to report the fault for repair. Among them, the display device can be the user's handheld terminal or the display device configured on the vehicle.

[0131] Step S640, in response to receiving a fault repair request, marking the current vehicle as a faulty vehicle and sending a vehicle replacement confirmation message.

[0132] After the user confirms a fault repair request based on the display device, the server marks the current vehicle as a faulty vehicle and temporarily stops the operation of the current vehicle. At the same time, the server sends vehicle replacement confirmation information to the display device to ask the user whether a vehicle replacement is needed.

[0133] Step S650: In response to receiving a vehicle replacement request, search for available vehicles nearby.

[0134] When the user needs to replace the vehicle, send a vehicle replacement request by confirming the replacement confirmation information sent by the display device. Based on the received vehicle replacement request, the server searches for available vehicles nearby to guide the user to the location of the available vehicle to complete the vehicle replacement.

[0135] In an embodiment of the present invention, by receiving target warning position information and available resource quantity, continuously update the available resource quantity according to the vehicle driving state, and in response to the available resource quantity reaching a predetermined threshold, control the vehicle to brake. Wherein, the target warning position information includes a target warning position, the target warning position is determined according to the vehicle position and the vehicle driving direction, and the available resource quantity represents the distance from the vehicle position to the target warning position or the time required to drive from the vehicle position to the target warning position. Thereby, braking of the vehicle is controlled when the vehicle reaches the target warning position, thus avoiding traffic accidents caused by brake failure.

[0136] Figure 7 is a flowchart of another vehicle braking method according to an embodiment of the present invention. As Figure 7 shown, the vehicle braking method according to an embodiment of the present invention includes the following steps:

[0137] Step S701: Determine the vehicle position and the vehicle driving direction.

[0138] In this embodiment, the vehicle position and the vehicle driving direction can be periodically determined by a positioning device and motion sensors such as a gyroscope provided on the vehicle, and the vehicle position and the vehicle driving direction are sent to the vehicle terminal.

[0139] Step S702: Send the vehicle position and the vehicle driving direction.

[0140] The vehicle terminal sends the determined vehicle position and vehicle driving direction to the server.

[0141] Step S703: Receive the vehicle position and the vehicle driving direction.

[0142] The server receives the vehicle position and vehicle driving direction sent by the vehicle terminal.

[0143] Step S704: Determine target warning position information according to the vehicle position and the vehicle driving direction.

[0144] The server filters the warning position information from the warning position information database according to the vehicle position and the vehicle driving direction, so as to determine the target warning position information.

[0145] Step S705, determine the available resource quantity based on the vehicle position and the target warning position.

[0146] The server calculates the distance from the vehicle position to the target warning position or the time required to drive from the vehicle position to the target warning position based on the vehicle position and the target warning position, so as to determine the available resource quantity.

[0147] Step S706, send the target warning position information and the available resource quantity.

[0148] The server sends the target warning position information and the available resource quantity to the vehicle.

[0149] Step S707, receive the target warning position information and the available resource quantity.

[0150] The vehicle receives the target warning position information and the available resource quantity sent by the server.

[0151] Step S708, continuously update the available resource quantity according to the vehicle driving state.

[0152] The vehicle updates the available resource quantity according to the vehicle position, the target warning position and the vehicle driving direction.

[0153] Step S709, control the vehicle to brake in response to the available resource quantity reaching a predetermined threshold.

[0154] In some embodiments, the warning position information database can be generated by the server in advance and sent to the vehicle. Thus, the vehicle can determine the target warning position information based on the warning position information database. Since the vehicle can obtain the vehicle position and the vehicle driving direction by itself, therefore, based on the target warning position information and the vehicle position, the vehicle can also determine the available resource quantity. Thus, the vehicle can perform the above data processing process of the server. Therefore, when the vehicle obtains the warning position information database in advance, the process of controlling the vehicle to brake can be realized only by the vehicle.

[0155] In an embodiment of the present invention, by receiving target warning position information and available resource amount, continuously updating the available resource amount according to the vehicle driving state, and in response to the available resource amount reaching a predetermined threshold, controlling the vehicle to brake. Wherein, the target warning position information includes a target warning position, and the target warning position is determined according to the vehicle position and the vehicle driving direction, and the available resource amount represents the distance from the vehicle position to the target warning position or the time required to drive from the vehicle position to the target warning position. Thus, braking of the vehicle is controlled when the vehicle reaches the target warning position, thereby avoiding traffic accidents caused by brake failure.

The brake monitoring device 84 is used to monitor the state of the manual brake system to determine whether the manual brake system is activated and whether the manual brake system is normal. The speed sensor 85 is used to detect the vehicle driving speed or acceleration to determine the vehicle deceleration amplitude. In some implementation manners, the average driving speed or acceleration of the vehicle can be calculated based on the vehicle driving speed detected by the speed sensor in this embodiment. In some implementation manners, the vehicle deceleration amplitude is determined based on the acceleration detected by the speed sensor. When the acceleration is negative, the greater the absolute value of the acceleration, the greater the deceleration amplitude.

[0157] In some embodiments, the central control device 81 is also communicatively connected to the server to send the vehicle position and the vehicle driving direction to the server, and receive the target warning position information and the available resource amount information sent by the server. The available resource amount represents the distance from the vehicle position to the target warning position or the time required to drive from the vehicle position to the target warning position, and the available resource amount is calculated and determined by the server based on the vehicle position, the vehicle driving direction, and the target warning position information. Further, the central control device 81 continuously updates the available resource amount according to the vehicle driving state, and in response to the available resource amount reaching a predetermined threshold, the central control device 81 controls the vehicle to brake.
