[0002] As a convenient means of transportation, cars greatly facilitate people's travel, but the number of casualties and property losses caused by traffic accidents during vehicle driving increases year by year. In traffic accident statistics, traffic accidents and casualties caused by speeding account for a large proportion of all traffic accident types.

[0003] Currently, the transportation department usually detects vehicle speeds through various detection equipment. However, it is impossible to monitor vehicle speeding on roads without detection equipment. In addition, if a vehicle fails to slow down, it is very likely that the vehicle will continue to exceed the speed limit. At this time, the detection equipment installed by the transportation department can only detect that the vehicle is speeding, and often cannot provide timely rescue for the faulty vehicle. If the rescue of the faulty vehicle is not timely, it is very likely to cause serious traffic accidents. Summary of the invention

[0126] Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein.

[0127] Figure 1 The flowchart of the first embodiment of a vehicle overspeed detection and rescue method provided by an embodiment of the present invention is shown. The vehicle overspeed detection and rescue method is executed by a vehicle overspeed detection and rescue device, wherein the vehicle overspeed detection and rescue device can be a software and hardware system set on the vehicle side, or a software system set on the cloud. Figure 1 As shown, the vehicle speeding detection and rescue method includes the following steps:

[0128] Step 110: Obtain the vehicle's driving speed at multiple moments.

[0129] Among them, the driving speeds at multiple moments need to be obtained within a continuous period of time when the vehicle is traveling. Based on the time sequence, the driving speeds at multiple moments are recorded. It should be noted that the formal speed at a specific moment can be the average speed within a driving distance, or it can be the instantaneous speed of the vehicle obtained based on time.

[0130] Step 120: When the driving speeds at the multiple moments meet the overspeed, the brake pedal openings corresponding to the multiple moments are obtained.

[0131] Among them, the speeding speed can be the maximum speed limit of the vehicle pre-set by the user or the vehicle service system, or it can be determined based on pre-set rules and the location of the vehicle. For example, the real-time location of the vehicle is obtained, and based on the real-time location of the vehicle, if the vehicle is on a highway section, the speeding speed is 120km / h; if the vehicle is on an urban road, the maximum speed limit corresponding to the urban road is obtained as the speeding speed.

[0132] It should be noted that, in some embodiments of the present invention, when judging whether the driving speeds at the multiple moments meet the speeding speed, a simple numerical comparison can be performed to judge whether the vehicle is speeding, that is, at a certain moment, if the driving speed is greater than the speeding speed, the vehicle is considered to be speeding; or the duration can be combined to judge whether the vehicle is speeding, that is, the vehicle is considered to be speeding only when the driving speed is greater than the speeding speed for a certain period of time.

[0133] Step 130: Based on the brake pedal openings corresponding to the multiple moments and the driving speeds at the multiple moments, generate first prompt information indicating that the vehicle is continuously speeding, or generate second prompt information indicating that the vehicle has a brake failure.

[0134] Among them, the purpose of obtaining the brake pedal opening corresponding to the multiple moments is to detect whether the user has a braking action, and to determine whether the vehicle has a braking fault based on the braking action and the driving speeds at multiple moments; specifically, first, the rate of change of the driving speed corresponding to the brake pedal opening in the driving speeds at multiple moments is obtained. It should be noted that obtaining the driving speed corresponding to the brake pedal opening in the driving speeds at multiple moments refers to the driving speed in the time period before and after detecting the brake pedal opening.

[0135] It should be noted that the technical solution of step 130 of the embodiment of the present invention can be applied to a normally traveling vehicle, and the driving speed of the vehicle can be obtained in real time, and the brake pedal opening of the vehicle can be recorded. In addition, it can also be applied to the data analysis level of the vehicle, for example, after a vehicle accident occurs, the control data recorded in the vehicle control system is obtained, and the brake pedal opening corresponding to the multiple moments and the driving speed at the multiple moments are extracted from the control data.

[0136] The interval corresponding to the time period before and after the detection of the brake pedal opening needs to be determined according to the type of the vehicle. For example, if the vehicle includes a brake energy recovery system, the time period before and after the detection of the brake pedal opening needs to be set to a longer time period, such as setting the time period from the moment the brake pedal opening is detected to 60 seconds after the brake pedal opening is 0. For another example, if the vehicle does not have a brake energy recovery system, the time period before and after the detection of the brake pedal opening needs to be set to a shorter time period, such as setting the time period from the moment the brake pedal opening is detected to 10 seconds after the brake pedal opening is 0.

[0137] It should be noted that, in actual application, there is a situation where the brake pedal opening is detected to be 0, that is, the brake pedal opening is not detected. In this case, the change rate of the driving speed is calculated based on the driving speed at all times.

[0138] After obtaining the rate of change of the driving speed corresponding to the brake pedal opening in the driving speed at multiple moments, the matching degree of the brake pedal opening and the rate of change is calculated; it should be noted that, when the brake pedal opening is the same, the driving speed of the vehicle is different, which causes a certain fluctuation in the rate of change of the driving speed, but when the braking function of the vehicle is normal, the rate of change of the driving speed is within a certain value. In actual application, the matching degree can be calculated directly based on the brake pedal opening and the rate of change, or on the basis of the brake pedal opening and the rate of change, a corresponding coefficient can be set according to the specific value of the current driving speed to calculate the matching degree of the brake pedal opening and the rate of change, so as to obtain a more accurate matching degree.

[0139] When the matching degree is within a preset interval, a first prompt message is generated indicating that the vehicle is continuously speeding. For example, the vehicle's speed at the first moment is 140 km / h, and after the user slightly steps on the brake pedal, the vehicle's speed at the second moment is 130 km / h. At this time, since the user only slightly steps on the brake pedal, the matching degree between the brake pedal opening and the change rate is within the preset interval, and the vehicle is judged to be in normal driving of the user, and is deemed to be speeding due to the user's active behavior, and a first prompt message is generated indicating that the vehicle is continuously speeding. It should be noted that the normal driving of the user mentioned here does not mean that speeding is a normal driving behavior, but only indicates that the vehicle is completely controlled by the user.

[0140] When the matching degree exceeds the preset interval, a second prompt message is generated indicating that the vehicle has a brake fault. For example, the vehicle's driving speed at the first moment is 140KM / H. After the user significantly steps on the brake pedal, the vehicle's driving speed at the second moment is 130KM / H. At this time, the matching degree between the brake pedal opening and the change rate exceeds the preset interval, and it is determined that the vehicle is not fully controlled by the user, and it is determined that the vehicle has a brake fault. At this time, a second prompt message indicating that the vehicle has a brake fault is generated.

[0141] It should be noted that when the vehicle is completely controlled by the user, if the vehicle is continuously speeding, in order to ensure traffic safety, the information that the vehicle has been speeding can also be pushed to the vehicle computer of the vehicle driven by the user, and the duration of the information that the vehicle has been speeding can be recorded at the same time; after the duration meets the preset duration, the vehicle's driving speed at multiple times is detected again; or within the preset duration, the vehicle's driving speed at multiple times is continuously detected, and if the vehicle's driving speed at multiple times detected again or continuously meets the speeding speed, a braking command for controlling the vehicle to decelerate is generated; the vehicle control system responds to the braking command to control the vehicle to decelerate until the vehicle's driving speed is within a safe speed range. In this way, the vehicle's driving safety is ensured as much as possible.

[0142] It should be noted that when pushing information to the user, the push information is pushed to the vehicle computer of the vehicle driven by the user. In the embodiment of the present invention, unless otherwise specified, when pushing information to the user, or pushing information to the user, the vehicle computer of the vehicle driven by the user is used as the receiving end of the push information. Of course, in actual application, it is not limited to using the vehicle computer as the receiving end of the push information, and other devices can also be used as the receiving end of the push information, for example, the user's handheld terminal is used as the receiving end of the push information.

[0143] Step 140: Send the first prompt information to a vehicle service system, or send the second prompt information to a roadside assistance system.

[0144] The vehicle service system may be a vehicle management backend or a customer service system of the manufacturer to which the vehicle belongs, which is used to remind the user that the vehicle has exceeded the speed limit, or as a normal driving data record of the vehicle, the road rescue system is used to provide rescue for the vehicle according to the second prompt information. The road rescue system may be a service platform maintained and operated by the manufacturer to which the vehicle belongs, such as a vehicle after-sales technical support team; or it may be a social public service platform, such as a traffic management department.

[0145] It should be noted that, in some embodiments of the present invention, the vehicle service system may also be associated with a traffic management department, and feed back the first prompt information to the traffic management department, so as to monitor whether the vehicle is speeding and urge users to drive safely.

[0146] It should be noted that after receiving the second prompt information, the road rescue system needs to carry out emergency rescue for the vehicle according to the responsibilities of the road rescue system to avoid traffic accidents caused by braking failure of the vehicle. Through this automatic detection method, after the vehicle has a braking safety hazard, it will be quickly fed back to the road rescue system to avoid the user being unable to deal with it calmly in an emergency, or even feeding back the fault information to the road rescue system.

[0147] It should be noted that, in actual application, the vehicle service system can also generate a second prompt message based on the vehicle information, and send the second prompt message to the road rescue system through the vehicle service system. Specifically, the vehicle side transmits the vehicle parameters to the vehicle service system, and the vehicle service system determines whether the vehicle's driving speed meets the speeding speed, and determines the brake pedal opening of the vehicle, and generates a first prompt message that the vehicle is continuously speeding, or generates a second prompt message that the vehicle has a brake failure, and after generating the second prompt message, sends the second prompt message to the road rescue system.

[0148] A vehicle speeding detection and rescue method provided by an embodiment of the present invention obtains the vehicle's driving speed at multiple times; when the driving speed at the multiple times meets the speeding speed, obtains the brake pedal opening corresponding to the multiple times; generates a first prompt message that the vehicle is continuously speeding, or generates a second prompt message that the vehicle has a brake failure, based on the brake pedal opening corresponding to the multiple times and the driving speed at the multiple times; sends the first prompt message to the vehicle service system, or sends the second prompt message to the road rescue system. The technical solution of the present invention can accurately monitor whether the vehicle is speeding, and when the vehicle is speeding due to a brake failure, the vehicle's brake failure information can be fed back to the road rescue system in a timely manner, so that the road rescue system can rescue the vehicle in a timely manner and avoid serious traffic accidents caused by the vehicle's brake failure as much as possible.

[0149] Figure 2 FIG. 2 is a flow chart showing another embodiment of a vehicle overspeed detection and rescue method provided by an embodiment of the present invention, wherein the vehicle overspeed detection and rescue method is performed by a vehicle overspeed detection and rescue device. Figure 2 As shown, the vehicle speeding detection and rescue method includes the following steps:

[0150] Step 210: Obtain the vehicle's driving speed at multiple times.

[0151] Step 220: When the driving speed at the first moment among the multiple moments is greater than the speeding speed, a speeding reminder message is generated, wherein the speeding reminder message is used to remind the user that the vehicle is speeding.

[0152] Step 230: When the driving speed at a second moment among the multiple moments is greater than the overspeed, the corresponding brake pedal opening in the time period from the first moment to the second moment is obtained.

[0153] The second moment is later than the first moment, and the time interval from the first moment to the second moment is in a preset time range.

[0154] The technical solution in the embodiment of the present invention is intended to detect vehicle speeding, especially speeding caused by vehicle failure. Therefore, in order to avoid the user's normal driving, if the user actively controls the vehicle to overspeed, the brake pedal opening of the vehicle is frequently detected; and there are some special circumstances in the normal driving of the vehicle. For example, when the vehicle is in emergency avoidance, it short-term overspeeds through a dangerous section. This will cause the vehicle's instantaneous speed to exceed the preset driving speed to a certain extent. If at this time, the brake pedal opening of the vehicle is directly detected, it is easy to cause the vehicle overspeed detection and rescue equipment to frequently start the brake pedal opening detection task, and it is easy to cause misjudgment. In some embodiments of the present invention, the driving speed at the first moment of multiple moments is obtained. When the driving speed at the first moment of multiple moments is greater than the speeding speed, an overspeed reminder message is generated, and the user is prompted with the information of the vehicle speeding by voice broadcast. At this time, the user can brake and control the vehicle according to the overspeed reminder message.

[0155] On this basis, the driving speed at the second moment among the multiple moments is obtained. When the driving speed at the second moment among the multiple moments is less than the speeding speed, it indicates that the vehicle is in the deceleration process, and there is no need to directly detect the brake pedal opening of the vehicle. When the second driving speed is greater than the preset driving speed, the corresponding brake pedal opening in the time period from the first moment to the second moment is obtained to determine whether the vehicle is completely under the control of the user.

[0156] Among them, the second moment is later than the first moment, and the time interval from the first moment to the second moment is in a preset time interval. For example, 15 seconds after obtaining the driving speed at the first moment among the multiple moments, the driving speed at the second moment among the multiple moments is obtained. It should be noted that the time interval between the first moment and the second moment may not be a fixed value, but is determined according to the specific value of the driving speed at the first moment among the multiple moments. For example, when the driving speed at the first moment is low, the time interval between the first moment and the second moment can be appropriately extended. When the driving speed at the first moment is high, the time interval between the first moment and the second moment can be appropriately shortened.

[0157] Step 240: Based on the brake pedal openings corresponding to the multiple moments and the driving speeds at the multiple moments, generate a first prompt message indicating that the vehicle is continuously speeding, or generate a second prompt message indicating that the vehicle has a brake failure.

[0158] Step 250: Send the first prompt information to a vehicle service system, or send the second prompt information to a roadside assistance system.

[0159] In some embodiments of the present invention, by judging whether the driving speed at the first moment among the multiple moments and the driving speed at the second moment among the multiple moments are greater than the speeding speed, it is judged whether the vehicle is fully controlled by the user. When the vehicle is fully controlled by the user, the user can be effectively urged to reduce the driving speed, and the brake pedal opening detection task is avoided to be frequently activated for vehicle speeding detection and rescue, and the occurrence of false alarms can be avoided to a certain extent.

[0160] It should be noted that after sending the second prompt information to the road rescue system, in order for the road rescue system to rescue the faulty vehicle quickly and accurately, the real-time position and real-time speed of the vehicle can also be obtained, and the obtained real-time position and real-time speed can be sent to the road rescue system.

[0161] In addition, the location information and driving direction of the vehicle can also be obtained; and based on the location information and driving direction of the vehicle, a safe area suitable for emergency avoidance of the vehicle can be determined; then the location information and navigation path of the safe area are pushed to the vehicle computer of the vehicle driven by the user, so that the user can be guided to drive the vehicle to a relatively safe area, for example, an avoidance lane set on the road, or for example, to a section of road with fewer vehicles.

[0162] In addition, due to a braking failure in the vehicle, personal injury may occur, or, in order to more accurately obtain vehicle information to serve rescue operations, after sending the second prompt information to the road rescue system, the vehicle's identity information and / or driver's identity information can also be obtained, and the vehicle's identity information and / or driver's identity information can be sent to the road rescue system.

[0163] Among them, after a brake failure occurs in a vehicle, in order to analyze the cause of the vehicle failure, after sending the second prompt information to the road rescue system, the vehicle's rescue work order can be obtained, and the rescue work order can be sent to the vehicle service system, wherein the time for obtaining the rescue work order can be to obtain a complete rescue work order after the vehicle is rescued, or to obtain the rescue status in real time during the rescue process of the vehicle. It should be noted that the rescue work order includes the vehicle's own data and also includes the interaction data with the road rescue system. In addition, the vehicle's operating status can be obtained in real time and sent to the vehicle service system, so that the vehicle service system can accurately obtain relevant data on the vehicle failure, and, based on the obtained operating status, analyze the solution to the vehicle failure, and to a certain extent, provide technical services on the vehicle to the road rescue system to improve the success rate of vehicle rescue.

[0164] A vehicle speeding detection and rescue method provided by an embodiment of the present invention obtains the vehicle's driving speed at multiple times; when the driving speed at the multiple times meets the speeding speed, obtains the brake pedal opening corresponding to the multiple times; generates a first prompt message that the vehicle is continuously speeding, or generates a second prompt message that the vehicle has a brake failure, based on the brake pedal opening corresponding to the multiple times and the driving speed at the multiple times; sends the first prompt message to the vehicle service system, or sends the second prompt message to the road rescue system. The technical solution of the present invention can accurately monitor whether the vehicle is speeding, and when the vehicle is speeding due to a brake failure, the vehicle's brake failure information can be fed back to the road rescue system in a timely manner, so that the road rescue system can rescue the vehicle in a timely manner and avoid serious traffic accidents caused by the vehicle's brake failure as much as possible.
