Example 1

FIG. 1 is a schematic flowchart of a method for regulating an air suspension according to Embodiment 1 of the present invention. The method can be applied to the situation of automatically adjusting the operating state of the air suspension, and is applied to a vehicle terminal. The method can be performed by an air suspension control device, which can be implemented in the form of hardware and/or software, and the air suspension control device can be configured on the vehicle end.

Automobile suspension is one of the important parts of the vehicle. As a force transmission part connecting the frame and the axle, the automobile suspension is not only an important part to ensure the riding comfort but also an important part to ensure the safety of the car, and the air suspension is a The best option to achieve this. The air suspension is mainly composed of a control computer, suction holes, exhaust holes, pneumatic front and rear shock absorbers and air distributors. When receiving the adjustment instruction, the control computer will control the air compressor and exhaust valve according to the adjustment instruction, so that the spring is automatically compressed or extended, thereby reducing or raising the ground clearance of the chassis to increase the stability of the high-speed vehicle body or complex road conditions passability.

For different road conditions, the air suspension can be set to the following operating states: normal mode, off-road mode and airflow mode. Among them, when the air suspension is adjusted to the normal mode, the body height is centered, which is more suitable for the vehicle to drive on urban roads; when the air suspension is adjusted to the off-road mode, the body height is higher, and the vehicle has good passability, which is more suitable for the vehicle to drive on the road. Driving on uneven roads such as off-road; when the air suspension is adjusted to the airflow mode, the body height is lower, which can reduce the wind resistance of the body and improve the fuel economy, which is more suitable for the vehicle to drive on the highway.

In the prior art, the user usually manually selects the operating state of the air suspension according to the driving road conditions. When there are complex and changeable road conditions during driving, in order to ensure the stability of the vehicle, the user will frequently adjust the operating state of the air suspension, which is easy to distract the user's attention during driving and affect the safety of public transportation. In addition, when it is impossible to find the problematic road ahead, and the complex situation of the user's blind spot occurs, it will lead to the problem of untimely adjustment, unstable driving, and affect the user's driving stability experience. Therefore, there is a need for a method that can solve the above problems.

As shown in FIG. 1 , the control method of the air suspension provided by the first embodiment may specifically include the following steps:

S110. Send the current driving feedback information of the vehicle to the cloud, so that the cloud can arbitrate and recommend the state of the air suspension according to the current driving feedback information.

The current driving feedback information includes: the current driving position, the current state of the air suspension, the current driving road image, and the current weather information. The arbitration recommendation can be understood as whether to adjust the operating state of the air suspension.

In this embodiment, the execution body is the vehicle terminal. During the running of the vehicle, the current driving position of the vehicle can be obtained from the positioning system of the vehicle, and the current state of the air suspension can be obtained from the air suspension system. The current driving road image is obtained in real time through a camera system such as a camera installed on the vehicle. Current weather information can be obtained from weather software installed on the vehicle.

Specifically, the acquired current driving position, the current state of the air suspension, the current driving road image, and the current weather information are uploaded to the cloud. After the cloud receives the current driving feedback information, it can arbitrate and recommend the status of the air suspension according to the current driving feedback information combined with the cloud suspension status recommendation algorithm. Exemplarily, the cloud can determine whether the current driving position is a bad road point according to the received current driving position and the pre-stored bad road point data, so as to further determine whether the current driving position is a bad road point and the current driving position of the air suspension. status to determine whether to adjust the operating status of the air suspension. The cloud can perform image recognition on the current driving road image to further determine whether to pass a bad road point, and determine whether to adjust the air suspension according to whether the vehicle is going to pass a bad road point and the current state of the air suspension. The cloud determines whether to adjust the air suspension according to the current weather information and the current state of the air suspension.

S120. After receiving the arbitration result sent by the cloud, if the arbitration result includes the first adjustment parameter for the air suspension, adjust the operating state of the air suspension according to the first adjustment parameter.

The arbitration result is determined by the cloud based on the current driving feedback information. The arbitration result may include tuning parameters for the air suspension, or it may not recommend suspension tuning. The first regulation parameter of the air suspension can be understood as a parameter that regulates the operating state of the air suspension to the off-road mode.

Specifically, after receiving the arbitration result sent by the cloud, if the arbitration result includes a control parameter for adjusting the operating state of the air suspension to an off-road state, the operating state of the air suspension is adjusted according to the control parameter.

An embodiment of the present invention provides a method for regulating and controlling an air suspension, which is applied to a vehicle-mounted terminal and includes: sending the current driving feedback information of the vehicle to the cloud, so that the cloud can adjust the status of the air suspension according to the current driving feedback information. Arbitration recommendation, where the current driving feedback information includes: current driving position, current state of the air suspension, current road image, and current weather information; after receiving the arbitration result sent by the cloud, if the arbitration result contains the first If the parameter is adjusted, the operating state of the air suspension is adjusted according to the first adjustment parameter; wherein, the arbitration result is determined by the cloud according to the current driving feedback information. Using this method, based on the current driving feedback information, the cloud makes an arbitration recommendation for the state of the air suspension, and the on-board terminal adjusts the operating state of the air suspension according to the arbitration result. Compared with the manual adjustment of the operation of the air suspension in the prior art state, the technical solution realizes the automatic adjustment of the operating state of the air suspension, and improves the safety and user experience.

As an optional embodiment of this embodiment, this optional embodiment further optimizes and defines, and the method further includes: if the air suspension is not recommended for suspension adjustment in the arbitration result, keeping the current operating state of the air suspension unchanged .

Specifically, if the cloud does not recommend adjusting the operating state of the air suspension, keep the current operating state of the air suspension unchanged.

Optionally, the received arbitration result is sent by the cloud after determining that the arbitration result meets the confidence condition.

In this embodiment, the arbitration result is determined according to the current weather information, the current driving position and the current driving road image, and the current weather information, the current driving position and the current driving road image can be used as influencing factors of the arbitration result. Different influencing factor settings account for different proportional weights. The confidence condition can be a preset weight ratio that needs to be satisfied for different influencing factors. Specifically, the arbitration result received by the vehicle terminal is sent by the cloud after determining that the arbitration result meets the confidence condition.

As an optional embodiment of this embodiment, this optional embodiment is further optimized and limited, and the method further includes: when the vehicle self-adjustment condition is satisfied, determining the second adjustment parameter of the air suspension according to the navigation data information of the vehicle, and according to The second adjustment parameter adjusts the operating state of the air suspension.

Among them, the vehicle self-adjustment condition is that it is detected that it is currently in a non-networked state; or, the arbitration result of the cloud feedback is not received within a set period of time after the current driving feedback information is sent.

This step can be understood as executing the local arbitration algorithm. When it is detected that it is currently in a non-networked state, or the arbitration result of the cloud feedback is not received within the set time period after sending the current driving feedback information, that is, the cloud does not recommend that the air suspension state needs to be adjusted within the set time period. Perform this step.

Wherein, the set duration may be set at the time of factory manufacture or set by the driver of the vehicle, which is not specifically limited here. The second adjustment parameter is distinguished from the first adjustment parameter, the first adjustment parameter refers to the adjustment parameter of the air suspension determined based on the cloud, and the second adjustment parameter refers to the adjustment parameter of the air suspension determined based on the self-adjustment of the vehicle. The second regulation parameter may be a parameter that regulates the operating state of the air suspension to be an off-road mode, a parameter that regulates the operating state of the air suspension to an airflow mode, or a parameter that regulates the operating state of the air suspension to a normal mode.

In this embodiment, the navigation data information of the vehicle may include information such as road segment gradient, road segment curvature, road segment congestion, and road type. The current driving road information can be obtained from the electronic map built in the vehicle. The vehicle self-adjustment is determined according to the road type and road condition information. Different road conditions or different road types are suitable for different air suspension operating modes. Exemplary, such as highways, it is suitable to adjust the air suspension to the airflow mode; when the road gradient is large, it is suitable to adjust the air suspension to the off-road mode. In this step, according to the road type and road condition information on which the vehicle travels, and based on the self-adjustment of the vehicle, it is determined which mode the air suspension operates in is more suitable. Among them, the operating state of the air suspension may be an off-road mode, an airflow mode or a normal mode.

Specifically, when it is detected that the current state of being disconnected from the Internet is detected; or, the arbitration result of the cloud feedback is not received within the set period of time after the current driving feedback information is sent, then the road segment gradient, road segment curvature and road congestion in the current driving road information are extracted. Happening. If the slope of the current road section reaches the set gradient threshold, or the curvature of the current road section reaches the set curvature threshold, or the congestion of the road section reaches the set congestion threshold, you need to adjust the air suspension to the off-road mode, and adjust the air suspension to enter the off-road mode. The parameter is determined as the second regulation parameter. If the slope of the current road segment does not reach the set gradient threshold, and the curvature of the current road segment does not reach the set curvature threshold, and the congestion of the road segment does not reach the set congestion threshold, it is necessary to further determine the current road type.

If the current road section is a high-speed road, the air suspension needs to be adjusted to the airflow mode, and the parameter for adjusting the air suspension to enter the airflow mode is determined as the second regulation parameter. Among them, the airflow mode is the operating state of the air suspension suitable for high-speed roads.

In order to describe the execution steps of vehicle self-regulation more clearly, FIG. 1a is a schematic flowchart of the execution steps of vehicle self-regulation provided by an embodiment of the present invention. As shown in Figure 1a, it specifically includes the following steps:

S11. If it is detected that it is currently in a non-networked state; or, the arbitration result of the cloud feedback is not received within the set time period after sending the current driving feedback information, then go to step S12;

S12, determine whether the slope of the current road section reaches the set gradient threshold, or whether the curvature of the current road section reaches the set curvature threshold, or whether the road section congestion has reached the set congestion threshold, if not, then go to step S13, if yes, go to step S14;

S13, determine whether the current road section is a high-speed road, if so, go to step S15, if not, go to step S16;

S14. It is recommended to switch the air suspension to off-road mode;

S15. It is recommended to switch the air suspension to airflow mode;

S16. It is recommended to switch the air suspension to normal mode.

As an optional embodiment of this embodiment, this optional embodiment is further optimized and limited, and the step of sending the current driving feedback information of the vehicle to the cloud can be specifically expressed as:

a1) Obtain the current state of the air suspension from the air suspension system of the vehicle, and obtain the current weather information, the current driving position, and the current driving road image captured by the camera in the vehicle.

Specifically, the current state of the air suspension and the current driving position can be obtained from the air suspension system of the vehicle. During the driving process of the vehicle, the position of the vehicle itself is constantly changing. The current driving position of the vehicle may be obtained through a vehicle positioning system built into the vehicle, such as a global positioning system (Global Positioning System, GPS) and a geographic information system (Geographic Information System, GIS). And capture the current driving road image through the camera in the vehicle. The current driving feedback information is composed of the current state of the air suspension, the current weather information, the current driving position and the current driving road image.

b1) When the information feedback conditions are met, the current state of the air suspension, the current weather information, the current driving position and the current driving road image are sent to the cloud as the current driving feedback information.

Wherein, the information feedback condition is receiving the information feedback triggering instruction; or, reaching the sending time of the information feedback.

Specifically, when the vehicle terminal receives the information feedback triggering instruction or reaches the sending time of the information feedback, the current state of the air suspension, the current weather information, the current driving position and the current driving road image are sent to the cloud as the current driving feedback information to the cloud. It enables the cloud to arbitrate and recommend the status of the air suspension according to the current driving feedback information.

This optional embodiment embodies the step of sending the current driving feedback information of the vehicle to the cloud. This optional embodiment sends the current status of the air suspension, the current weather information, the current driving position, and the current driving road image captured by the camera in the vehicle to the cloud. to the cloud, so that the cloud can automatically determine whether the operating status of the air suspension needs to be adjusted according to the current driving feedback information.

S220. Determine whether to adjust the state of the air suspension of the vehicle according to the current driving feedback information.

In this embodiment, historical record data about each bad road point in the road section is stored in the cloud. The historical record data contains information about bad road points. Bad road points can be understood as potholes where the road surface is damaged. Bad road points have a certain impact on vehicle driving. The historical record data includes the received bad road point information, and the driving bad road point information may include the specific location of the bad road point, the width and depth of the pothole, the name of the road section it belongs to, and the collection time. The construction method of the bad road point database may be to collect the driving bad road point information reported by the user.

Among them, the historical record data includes all the collected bad road point information. Specifically, after receiving the current driving position of the vehicle, the historical record data includes the bad road point information, traverses the bad road point information in the bad road point database, and extracts the bad road point position from the bad road point information, Match the current driving position of the vehicle with the position of each bad road point. If the matching is successful, it is determined that there is a bad road point in the current driving position. If the matching is unsuccessful, it is determined that there is no bad road point at the current driving position. In order to further determine whether the bad road point is a real bad road point, the source of the historical record data corresponding to the determined bad road point can be determined to determine the authenticity of the historical record data, so as to determine that the determined bad road point is a real bad road point .

In this embodiment, if the determination result is that there are bad road points in the current driving section, it indicates that the vehicle will encounter bad road points in the current driving section. Adjusts the operating state of the air suspension to off-road mode, allowing the vehicle to smoothly pass through bad road spots. When the vehicle has passed the bad road point and entered the normal road section, the operating state of the air suspension needs to be adjusted to the normal mode. Specifically, if the determination result is that there is a bad road point in the current driving road section, it is determined that the state adjustment of the air suspension is performed, and the adjustment parameters are determined; otherwise, it is determined that the state adjustment of the air suspension is not performed.

Compare the current air suspension state with the determined air suspension state to be adjusted. If the current air suspension is the air suspension state to be adjusted, the air suspension state does not need to be adjusted. If the current air suspension is not For the air suspension state to be adjusted, the air suspension state needs to be adjusted, and the adjustment parameters can be determined, so that the vehicle end can adjust the air suspension operation state according to the adjustment parameters.

Further, whether there is an abnormal road condition is identified in the current driving road image based on the current driving feedback information, and whether to adjust the air suspension state is determined according to the abnormal road condition.

Further, if the weather in the current area is bad and meets the set weather conditions, it is considered that the bad road point will affect the driving of the vehicle, and the air suspension needs to be adjusted to the off-road mode when passing through the bad road point. The weather conditions can be haze, heavy fog, heavy rain, icing or typhoon. For such bad weather, the air suspension needs to be adjusted to off-road mode, and the air suspension adjustment parameters are determined. Otherwise, there is no need to adjust the air suspension to off-road mode.

S230. If yes, obtain the first adjustment parameter for the air suspension and use it as the arbitration result.

Specifically, if it is necessary to adjust the state of the air suspension of the vehicle, the first adjustment parameter for the air suspension is obtained and used as the arbitration result.

S240. If no, suspension adjustment is not recommended as the arbitration result for the air suspension.

Specifically, if it is determined that the state adjustment of the air suspension of the vehicle is not required, the suspension adjustment is not recommended as the arbitration result for the air suspension.

S250. Perform confidence condition judgment on the arbitration result, and feed back the arbitration result satisfying the confidence condition to the vehicle terminal.

In this embodiment, the arbitration result is determined according to the current weather information, the current driving position and the current driving road image, and the current weather information, the current driving position and the current driving road image can be used as influencing factors of the arbitration result. Different influencing factor settings account for different proportional weights. The confidence condition can be a preset weight ratio that needs to be satisfied for different influencing factors. Specifically, a confidence condition judgment is performed on the arbitration result, and the arbitration result satisfying the execution condition is fed back to the vehicle terminal.

An embodiment of the present invention provides a control method for an air suspension. The method is applied to the cloud and includes: receiving current driving feedback information of a vehicle uploaded by a vehicle terminal; and determining whether to adjust the air suspension of the vehicle according to the current driving feedback information. state adjustment; if so, obtain the first adjustment parameter for the air suspension and use it as the arbitration result; if not, take the suspension adjustment not recommended as the arbitration result for the air suspension; perform a confidence condition judgment on the arbitration result, which will satisfy the The arbitration result of the confidence condition is fed back to the vehicle terminal. Using this method, based on the current driving feedback information, it is determined whether to adjust the state of the air suspension of the vehicle, and the arbitration result is determined, the confidence condition of the arbitration result is judged, and the arbitration result satisfying the confidence condition is fed back to the vehicle terminal. Compared with the manual adjustment of the operating state of the air suspension in the prior art, the technical solution realizes the automatic adjustment of the operating state of the air suspension, thereby improving safety and user experience.

As an optional embodiment of this embodiment, this optional embodiment further optimizes and limits, and determines whether to adjust the state of the air suspension of the vehicle according to the current driving feedback information, including:

a2) According to the current driving position in the current driving feedback information, determine the current driving section where the vehicle is located.

Wherein, the current driving section refers to a small area determined with the current driving position as the center. Specifically, the current driving section where the vehicle is located is determined according to the current driving position in the current driving feedback information.

b2) Searching for pre-stored historical record data, wherein the abnormal road condition information included in the historical record data is reported by the driving user.

Among them, the historical record data refers to the data used to provide the saved driving bad road point information. Only through the bad road point information and the current driving section of the vehicle can it be determined whether there is a bad road point in the current driving section, so as to perform the subsequent steps. Therefore, the construction step of the history data is a step performed in advance in this embodiment.

The construction steps of historical record data can be expressed as: when the user encounters a bad road point, the user determines the road surface condition corresponding to the bad road point, and through the human-computer interaction interface provided by the vehicle terminal, the road surface condition is input into the vehicle and submitted to form a driving Bad road point information, the vehicle sends the bad road point information to the cloud. The driving bad road point information includes, but is not limited to: the bad road point location, the width and depth of the bad road point pothole, the source of collection, the time of information submission, etc. The cloud receives the bad road point information submitted by each user through each vehicle, and aggregates the bad road point information received during the historical time period as historical record data. In practical application scenarios, the person reporting the bad road point information may be an ordinary user or a professional user.

If the collection source is an ordinary user, it is necessary to determine whether the storage condition is satisfied according to the driving bad road point information, and determine whether the bad road point corresponding to the driving bad road point information is a real bad road point. When the driving bad road point information is uploaded by a common user, it is judged whether the user has provided a picture of the current area captured by the vehicle camera, and if there is a relevant picture, it is identified whether the picture contains bad road points such as potholes, if it contains bad road points , then it is determined that the bad road point corresponding to the driving bad road point information is a real bad road point, and the driving bad road point information is stored as the historical record data as the real data.

If the vehicle is not equipped with an on-board camera or the photos taken by the on-board camera are blurry, fail to provide a clear picture of the current area, or no potholes are identified, continue to determine whether the current user's credit rating exceeds the set credit threshold. The credibility of the current user represents the reliability of the information provided by the current user. The user's credit can be determined based on the vehicle's acquisition of the user's credit from a third-party system, such as whether the user has violated traffic rules, whether there is any overdue repayment behavior, etc., to determine the user's credit rating. The credit threshold can be set according to practical experience. For example, if the credit is divided into 0-100, a credit of 0 means completely unreliable, and a credit of 100 means completely reliable, then 80 can be set as the set credit threshold. If the current user credit is greater than the set credit threshold, the information provided by the current user is considered to be credible, the bad road point corresponding to the provided driving bad road point information is a real bad road point, and the driving bad road point information is stored as real data to the historical data.

If the current user credit is less than the set credit threshold, it is necessary to continue to judge whether the current user drives the vehicle to adjust the operation mode of the air suspension to the off-road mode in the current area, and if so, determine that the bad road corresponding to the bad road point information is true. Bad road points, and store the driving bad road point information as real data as historical record data.
