[0047] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0048] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0049] First, a method for detecting road bumps on the vehicle side will be described.

[0050] Figure 1 This is a flow chart of a method for detecting road bumps provided in an embodiment of the present disclosure. The method provided in an embodiment of the present disclosure can be executed by a device for detecting road bumps, which can be implemented in software and / or hardware and can be integrated on any electronic device with computing capabilities.

[0051] like Figure 1 As shown, the method for detecting road bumps provided by the embodiment of the present disclosure may include:

[0052] Step 101, obtaining vehicle bump detection data.

[0053] In this embodiment, the bump detection data is obtained at the vehicle end, and the bump detection data can be used to determine whether there is bump. Optionally, the vehicle is provided with a sensor, and the bump detection data of the vehicle during driving is obtained through the sensor, thereby obtaining the bump detection data of the vehicle at various times. The bump detection data includes but is not limited to the distance between the wheel guard and the tire of the vehicle, the gravity measurement value of the seat, the tension measurement value of the seat belt, the acceleration in the vertical direction, etc.

[0054] Step 102: When the bump detection data meets the preset bump determination condition, determine the target time for the bump detection data to meet the preset bump determination condition.

[0055] In this embodiment, the bump determination condition is set to determine that the road bump exists when the bump detection data satisfies the bump determination condition. The bump detection data of the vehicle at each time is matched with the preset bump determination condition. When the bump detection data satisfies the bump determination condition, the time corresponding to the bump detection data satisfying the bump determination condition is determined as the target time when the road bump exists.

[0056] Optionally, the bump detection data includes at least one of the distance between the vehicle wheel guard and the tire, the gravity measurement value of the seat, and the tension measurement value of the seat belt, and the vehicle is provided with a distance sensor, a seat weight sensor, and a seat belt tension sensor, such as Figure 2 shown.

[0057] The following is an example of satisfying the bump determination conditions in combination with the bump detection data.

[0058] As an example, the bump detection data satisfies the preset bump determination condition, including: if the first difference between the maximum distance value and the minimum distance value between the wheel guard and the tire of the vehicle within the first time range is greater than or equal to the first threshold, then it is determined that the preset bump determination condition is met. In this example, the distance between the wheel guard and the tire of the vehicle is detected by the distance sensor, and the distance is used to represent the gap size between the wheel guard and the tire, such as Figure 3 As shown, Figure 3 A schematic diagram of distance detection between a tire and a wheel guard is shown, in which the horizontal axis represents time and the vertical axis represents distance change. Figure 3 The above is the distance diagram under normal conditions. Under normal conditions, the turbulence determination condition is not met. Figure 3 The following is a distance diagram in a dynamic unbalanced state. The bump determination condition is met in a dynamic unbalanced state. In the distance diagram in a dynamic unbalanced state, frame 31 represents a first time range. The duration of the first time range is a preset duration. In the first time range, the distance between the vehicle wheel guard and the tire first decreases to the minimum distance value, then increases to the maximum distance value, and finally returns to the initial distance value. The first difference between the maximum distance value and the minimum distance value in the first time range is greater than or equal to the first threshold value, indicating that the gap between the wheel guard and the tire fluctuates abnormally within the first time range, and the distance between the two changes dramatically. Therefore, it is determined that there is road bumps, and it is determined that the bump determination condition is met at this time. Optionally, the first threshold value can be determined based on experimental data, and the target time can be the starting time of the first time range, or it can be any time within the first time range. Thus, the road bump condition at the location can be accurately determined by the gap between the tire and the wheel guard.

[0059] As another example, if the second difference between the maximum gravity measurement value and the minimum gravity measurement value within the second time range is greater than or equal to the second threshold, it is determined that the preset bump determination condition is met. In this example, the gravity measurement value of the seat subjected to the gravity of the object above the seat is detected by the seat weight sensor, and the duration of the second time range is a preset duration. Within a second time range, the initial gravity measurement value first decreases to the minimum gravity measurement value, which is, for example, about one-tenth of the initial gravity measurement value, and then increases to the maximum gravity measurement value, and finally returns to the initial gravity measurement value, indicating that the gravity of the object above the seat detected has changed dramatically, so it is determined that there is road bumps, and at this time it is determined that the bump determination condition is met. Optionally, the target time can be the starting time of the second time range, or it can be any time within the second time range. Thus, the road bump condition at the location can be accurately determined by the detected gravity change of the object above the seat.

[0060] As another example, if the tension measurement value is greater than or equal to the third threshold, it is determined that the preset bump determination condition is met. In this example, the tension on the seat belt is detected by a seat belt tension sensor.

[0061] It should be noted that in actual applications, any one of the above examples can be used to determine whether the bump determination condition is met, or a combination of the above examples can be used to determine whether the bump determination condition is met. For example, when the first difference between the maximum distance value and the minimum distance value of the distance between the vehicle wheel guard and the tire within the first time range is greater than or equal to the first threshold, and the second difference between the maximum gravity measurement value and the minimum gravity measurement value within the second time range is greater than or equal to the second threshold, and the tension measurement value is greater than or equal to the third threshold, it is determined that the bump determination condition is met, thereby accurately identifying road bumps.

[0062] Step 103, obtaining first bump position information and a first vehicle speed at a target time.

[0063] The first bump position information is the position information of the vehicle at the target time.

[0064] Step 104: If the first vehicle speed is greater than or equal to a preset vehicle speed threshold, the first vehicle speed and the first bump position information are sent to the cloud.

[0065] In this embodiment, the position information and speed of the vehicle during the driving process are obtained, and after determining the target time when the bump detection data meets the preset bump determination condition, the speed of the vehicle at the target time is obtained as the first vehicle speed, and the position information of the vehicle at the target time is obtained as the first bump position information. Then, the first vehicle speed is compared with the preset vehicle speed threshold, and if the first vehicle speed is greater than or equal to the preset vehicle speed threshold, the first vehicle speed and the first bump position information are sent to the cloud as a combination information, so that the cloud generates the final road bump detection result according to the multiple combination information sent by each vehicle, and if the first vehicle speed is less than the preset vehicle speed threshold, the first vehicle speed and the first bump position information are not sent.

[0066] The preset vehicle speed threshold may be set according to actual conditions. For example, the preset vehicle speed threshold is 60 km / h. For another example, the preset vehicle speed threshold is any value whose difference from 60 km / h is less than the threshold.

[0067] In a vehicle driving scenario, when a vehicle passes through a road with poor road conditions or a speed-limited road, the vehicle's driving speed is low and the driver is more focused on the road conditions. When the driver finds that there may be bumps on the road, he will reduce the speed to reduce bumps. At this time, if bump prompts or even frequent prompts are given, it will affect the driving experience. According to the bump prompt method in the relevant technology, prompt information is generated when road bumps are detected. For example, when a vehicle passes through a country road, it will cause continuous prompts when the vehicle passes through the road section, or frequent unnecessary prompts will be generated, affecting the driver's driving experience.

[0068] According to the technical solution of the embodiment of the present disclosure, at the target time when the vehicle's bump detection data meets the preset bump determination condition, the first vehicle speed of the vehicle at the target time is obtained, and when the first vehicle speed of the vehicle is greater than or equal to the preset speed threshold, the vehicle sends the first vehicle speed and the first bump position information to the cloud. Therefore, when the cloud determines the road bump position, it will not record the bump position where the vehicle speed is less than the preset speed threshold when the bump occurs. The road bump position determined in the above manner is used for bump prompts, thereby reducing unnecessary prompts. In addition, when determining the road bump position, the vehicle speed that will cause the bump is also determined, and a more accurate bump prompt can be made based on the vehicle speed, thereby reducing unnecessary prompts and improving the driver's driving experience.

[0069] The following is an explanation of the method for detecting road bumps in the cloud.

[0070] Based on the above embodiments, Figure 4 A flow chart of another method for detecting road bumps provided by an embodiment of the present disclosure is shown as follows: Figure 4 As shown, the method includes:

[0071] Step 401, receiving first vehicle speed and first bump position information sent by a vehicle.

[0072] The first vehicle speed and the first bump position information are determined when the bump detection data of the vehicle meets a preset bump determination condition.

[0073] In this embodiment, for each vehicle, when the vehicle detects road bumps, the first vehicle speed and the first bump position are determined through the steps of the aforementioned embodiments, and when the first vehicle speed is greater than or equal to a preset vehicle speed threshold, the first vehicle speed and the first bump position information are sent to the cloud as a combined message. Each vehicle can send multiple combined messages to the cloud during driving, and the cloud receives multiple combined messages sent by each of the multiple vehicles, thereby obtaining the first vehicle speed and the first bump position information sent by the vehicle.

[0074] Step 402 , performing deduplication processing on all first bump position information to obtain at least one second bump position information, and determining at least one first vehicle speed corresponding to each second bump position information.

[0075] In this embodiment, there may be duplications in all the first bump position information received by the cloud, for example, the same vehicle passes the same bumpy road surface multiple times, or different vehicles pass the same bumpy road surface. Therefore, the cloud performs deduplication processing on all the first bump position information to obtain at least one non-repetitive second bump position information, and determines the first vehicle speed corresponding to the second bump position information based on the first vehicle speed corresponding to the repeated first bump position information.

[0076] As an example, for N first bump position information, if M of the first bump position information are at the same position, second bump position information representing the position will be generated, and the M first vehicle speeds corresponding to the M first bump position information will be used as the M first vehicle speeds corresponding to the second bump position information.

[0077] Step 403: for each second bump position information, determine a second vehicle speed with the minimum vehicle speed from at least one first vehicle speed corresponding to each second bump position information.

[0078] In this embodiment, for a second bump position information, if the second bump position information corresponds to a first vehicle speed, the first vehicle speed is used as the second vehicle speed corresponding to the second bump position information; if the second bump position information corresponds to multiple first vehicle speeds, the minimum vehicle speed is determined from the multiple first vehicle speeds, and the minimum vehicle speed is used as the second vehicle speed corresponding to the second bump position information.

[0079] The second vehicle speed is used to indicate the minimum vehicle speed at which the vehicle will bump when passing the second bump position information.

[0080] Step 404: Send each second bump position information and the second vehicle speed corresponding to each second bump position information to the vehicle.

[0081] In this embodiment, for each second bump position information, the second bump position information and the corresponding second vehicle speed are sent to all vehicles as one feedback message, so that each vehicle provides a road bump prompt according to the multiple feedback messages sent from the cloud.

[0082] According to the technical solution of the embodiment of the present disclosure, by determining the target time when the vehicle's bump detection data meets the preset bump determination condition, the first vehicle speed of the vehicle at the target time is obtained. When the first vehicle speed of the vehicle is greater than or equal to the preset speed threshold, the vehicle sends the first vehicle speed and the first bump position information to the cloud. Then, the cloud determines the minimum vehicle speed at which the vehicle bumps when passing the second bump position information as the second vehicle speed based on the first vehicle speed, and uses the second vehicle speed and the second bump position information for bump prompts. Therefore, when determining the road bump position, the cloud will not record the bump position where the vehicle speed is less than the preset speed threshold when the bump occurs. The road bump position determined in the above manner is used for bump prompts, thereby reducing unnecessary prompts. In addition, when determining the road bump position, the speed that will cause bumps is also determined, and more accurate bump prompts can be made based on the speed, which can reduce unnecessary prompts and improve the driver's driving experience.

[0083] Based on the above embodiments, Figure 5 A flow chart of another method for detecting road bumps provided by an embodiment of the present disclosure is shown as follows: Figure 5 As shown, the method includes:

[0084] Step 501: The cloud sends the second bump position information to the vehicle.

[0085] In this embodiment, the cloud sends each second bump position information and the second vehicle speed corresponding to each second bump position information to all vehicles, and the vehicles receive multiple feedback information, each feedback information includes a second bump position information and the second vehicle speed corresponding to the second bump position information.

[0086] Step 502: The vehicle receives the second bump position information sent by the cloud, and obtains the bump detection data when the vehicle passes the second bump position information.

[0087] In this embodiment, for each second bump position information, when the vehicle passes through the second bump position information, the bump detection data when the vehicle passes through the second bump position information is obtained. The bump detection data includes but is not limited to the distance between the wheel guard and the tire of the vehicle, the gravity measurement value of the seat, the tension measurement value of the seat belt, the acceleration in the vertical direction, etc.

[0088] Step 503: The vehicle determines update information of the second bump position information and sends the update information to the cloud.

[0089] In this embodiment, if the bump detection data when the vehicle passes the second bump position information does not meet the preset bump determination condition, then update information of the second bump position information is generated and sent to the cloud. For example, taking the distance between the wheel guard and the tire of the vehicle as an example, if the distance between the wheel guard and the tire of the vehicle does not meet the preset bump determination condition when the vehicle passes the second bump position information, then update information is generated. Optionally, if the bump detection data when the vehicle passes the second bump position information does not meet the preset bump determination condition, and the vehicle speed when the vehicle passes the second bump position information is greater than or equal to the second vehicle speed corresponding to the second bump position information, then update information of the second bump position information is generated, and the update information is used to indicate that there is no road bump in the second bump position information.

[0090] Step 504: The cloud updates the second bump position information according to the update information sent by the vehicle.

[0091] In this embodiment, the cloud receives update information of the second bump position information sent by the vehicle. For example, the cloud receives multiple update information sent by multiple vehicles. The multiple update information may correspond to the same second bump position information or may correspond to different second bump position information. The update information is generated when the bump detection data when the vehicle passes the second bump position information does not meet the preset bump determination condition. Then, the cloud determines the number of update information of each second bump position information. For any target position information in the second bump position information, if the number of update information of the target position information is greater than the preset number, the target position information is deleted in the second bump position information. Thus, for the determined second bump position information, if multiple vehicles subsequently pass the position, if it is detected that there is no road bump at the position, the bump state of the position in the cloud is updated. By deleting the second bump position information, the road bump prompt for the position is cancelled, and the accuracy of the road bump prompt is further improved.

[0092] Based on the above embodiments, Figure 6 A flowchart of another method for indicating road bumps provided by an embodiment of the present disclosure is shown in FIG. Figure 6 As shown, the method includes:

[0093] Step 601: Receive second bump position information and a second vehicle speed corresponding to the second bump position information.

[0094] The second bump position information and the second vehicle speed are obtained by using the road bump detection method as described in the above-mentioned embodiment.

[0095] In this embodiment, the cloud sends each second bump position information and the second vehicle speed corresponding to each second bump position information to all vehicles. As an example, after determining the second bump position information, the cloud updates the navigation system according to the second bump position information to provide bump prompts to the vehicle through the navigation system.

[0096] Step 602, in response to the current position information of the vehicle satisfying the bump prompt condition for the second bump position information, obtaining the current speed of the vehicle.

[0097] In this embodiment, it is determined whether the bump prompt condition for the second bump position information is met based on the current position information of the vehicle. When the bump prompt condition for the second bump position information is met, it is determined that the vehicle is about to pass the second bump position information, and the current vehicle speed of the vehicle is obtained. Alternatively, it can be determined based on a navigation system whether the vehicle is about to pass the second bump position information.

[0098] In one embodiment of the present disclosure, the current position information of the vehicle satisfies the bump prompt condition for the second bump position information, including: determining a prompt range of the second bump position information according to the second vehicle speed, and when the current position information of the vehicle is within the prompt range of the second bump position information, determining that the bump prompt condition for the second bump position information is satisfied. The second vehicle speed is proportional to the size of the prompt range.

[0099] As an example, the second vehicle speed corresponding to the second bump position information is 120km / h, and the navigation system gives a bump prompt at a distance of 500 meters from the bump position by default. Alternatively, the preset corresponding relationship is queried based on the second vehicle speed 120km / h, and it is determined that a bump prompt is given when the vehicle is 1km away from the bump position. In this way, the range of the bump prompt can be dynamically adjusted according to the vehicle speed at which bumps will occur corresponding to different bump positions, thereby improving the driving experience.

[0100] Step 603: If the current vehicle speed is greater than or equal to the second vehicle speed, then generate bump prompt information to provide a road bump prompt for the second bump position information.

[0101] In this embodiment, when the vehicle position meets the bump prompt condition for the second bump position information, it is further determined whether the current vehicle speed is greater than or equal to the second speed. If the current vehicle speed is less than the second speed, that is, the current vehicle speed is less than the minimum speed at which the vehicle bumps when passing the second bump position information, it is determined that the vehicle will not bump when passing the second bump position information at the current speed. At this time, no bump prompt is required, which reduces unnecessary prompt information and improves the driving experience. When the current vehicle speed is greater than or equal to the second speed, bump prompt information is generated to provide a road bump prompt for the second bump position information, so that the driver can understand that there are road bumps ahead. The driver can slow down by notifying him in advance, thereby reducing bumps and improving passenger comfort.

[0102] Optionally, generating the bump warning information includes: determining a third vehicle speed based on the second vehicle speed, wherein the third vehicle speed is less than the second vehicle speed; and then generating the bump warning information based on the third vehicle speed to prompt the vehicle speed to be reduced to below the third vehicle speed.

[0103] As an example, the second vehicle speed is 85km / h, and the third vehicle speed can be 80km / h, that is, the bump prompt information is used to prompt the driver that there are bumps on the road ahead, and to prompt the driver to pass through the bumps at a speed below 80km / h. For another example, if 65km / h ≥ the second vehicle speed ≥ 60km / h, the speed is prompted to be reduced to below 60km / h; if 70km / h ≥ the second vehicle speed > 65km / h, the speed is prompted to be reduced to below 65km / h, etc., and no specific restrictions are made here. Therefore, the bump prompt information is determined by the specific speed, so that the driver can more clearly understand the speed that needs to be reduced, further improving the driving experience.

[0104] According to the technical solution of the disclosed embodiment, when the cloud determines the position of road bumps, it will not record the bump position where the vehicle speed is less than the preset speed threshold when the bump occurs. The road bump position determined in the above manner is used for bump prompts, thereby reducing unnecessary prompts. Moreover, when determining the road bump position, the vehicle speed that will cause the bump is also determined, and more accurate bump prompts can be made based on the vehicle speed. While meeting the need for bump prompts for high-speed driving scenarios to reduce bumps, unnecessary prompts can be reduced, thereby improving the driver's driving experience.

[0105] Based on the above embodiments, the present disclosure also proposes a road bump detection system, which includes a cloud and multiple vehicles, wherein the cloud and multiple vehicles can implement the methods of the above embodiments, which will not be repeated here.
