Detailed Description

Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with aspects of the present application.

At present, vehicles have become an important vehicle for human travel. In order to ensure the safety of the vehicle during driving, different roads are usually corresponding to different speed limit marks so as to remind a driver to control the vehicle to decelerate.

However, the speed limit marks on two sides of the road are easily ignored by the driver, and cannot play a role in effective prompt.

In one example, not only speed limit marks can be arranged at two sides of a road, but also a speed reduction belt can be arranged in the middle of the road, and when a user drives a vehicle to run through the speed reduction belt, vibration brought by the speed reduction belt can be used for playing a speed reduction reminding for a driver. However, the height of the deceleration strip arranged in the current road is usually a fixed value and cannot be adjusted, so that a driver driving for a long time is easy to get used to the vibration brought by the deceleration strip, and an effective vibration prompt effect cannot be achieved.

The deceleration prompt method, the deceleration prompt device and the deceleration prompt equipment based on the deceleration strip are used for solving the technical problems.

According to the deceleration prompt method, the deceleration prompt device and the deceleration prompt equipment based on the deceleration strip, through predicting the predicted running speed of the vehicle when passing through the deceleration strip, when the predicted running speed is larger than the preset threshold, at the moment, the height value which the deceleration strip should adjust can be determined based on the vehicle related information of the vehicle and the predicted running speed of the vehicle, and then the deceleration strip is controlled to be adjusted to the adjusted height value, so that effective deceleration prompt can be carried out on different vehicles.

The following describes the technical solutions of the present application and how the technical solutions of the present application solve the above technical problems in detail with specific embodiments. The following embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments. Embodiments of the present application will be described below with reference to the accompanying drawings.

Fig. 1 is a flow chart of a deceleration prompt method based on a deceleration strip according to an embodiment of the present application, as shown in fig. 1, the method includes the following steps:

s101, obtaining a predicted running speed of a vehicle passing through a deceleration strip; the predicted travel speed is a predicted speed at which the vehicle passes through the deceleration strip.

Illustratively, the speed bump height of the speed bump mentioned in the embodiments of the present application is adjustable. The execution body of the embodiment may be a controller of a deceleration strip, or may be an electronic device such as a remote server, which is not particularly limited herein. In this embodiment, an execution body is described as an example of an electronic device.

When it is determined that there is a vehicle to pass through the deceleration strip, the predicted travel speed at which the vehicle passes through the deceleration strip is predicted.

In one example, the vehicle has an automatic driving planning function, that is, the vehicle itself can plan a route in a future driving process of the vehicle and a vehicle speed in the future driving process, and the electronic device can request the vehicle to acquire the speed of the vehicle when the vehicle is driven to the deceleration strip when the vehicle is planned.

In one example, the vehicle may determine vehicle speed information of the vehicle based on a radar or other detection means mounted on the vehicle thereof, and the electronic device may directly take the vehicle speed at the current time of the vehicle that is about to pass through the deceleration strip as the predicted running speed at which the vehicle continues to run and passes through the deceleration strip.

S102, if the predicted running speed is determined to be greater than a preset threshold value, acquiring vehicle association information of the vehicle; wherein the vehicle-related information includes one or more of: current weight information, vehicle category information, weather information, shape information of the speed bump, current height of the speed bump.

For example, the preset threshold in the present embodiment may be determined based on the speed limit of the road on which the deceleration strip is located. When the electronic equipment determines that the preset running speed is greater than the preset threshold value by comparing the predicted running speed and the preset threshold value, the phenomenon that overspeed is possibly caused to the vehicle at the moment is indicated, and in order to effectively remind the deceleration of the vehicle, vehicle related information of the vehicle can be acquired.

Wherein the current weight information in the vehicle-related information is used to characterize the current weight value of the vehicle. When the current weight information is acquired, the current weight value of the vehicle may be determined by a gravity detection device provided in the road itself. Alternatively, the current weight information of the vehicle may be determined by analyzing an image of the vehicle to determine information such as a model of the vehicle, cargo carried by the vehicle, passengers in the vehicle, and the like, and the acquisition of the current weight information is not particularly limited herein.

The vehicle type information in the vehicle-related information may be used to indicate a vehicle model of the vehicle. Weather information, which may be used to indicate the weather in which the vehicle is currently located, such as: raining, snowing, sunny days and road icing. The weather information can be obtained in a networking mode, and can also be obtained by carrying out image processing analysis on an environment information image where the deceleration strip is currently located. Shape information of the deceleration strip, for example, a value of a dimensional parameter of the deceleration strip in each direction. The current height of the speed bump, i.e. the distance between the speed bump and the road surface on which the speed bump is located.

It is understood that the jerk felt by the driver of the vehicle when the vehicle is traveling through the speed bump is related to the traveling speed of the vehicle when the vehicle is traveling through the speed bump and the weight of the vehicle. In addition, because the effects of the shock absorbers configured by different vehicles are different, the shock absorbing effect corresponding to the model information of the vehicles can be obtained in a combined mode, so that the shock absorbing effect felt by the vehicles when the vehicles pass through the deceleration strip can be further determined.

In addition, the shock absorbing effect felt by the driver when the vehicle passes through the speed bump is related not only to the parameters of the vehicle itself but also to the shape of the speed bump in the road, that is, the shape of the speed bump affects the stress when the vehicle passes through the speed bump.

In addition, it is also conceivable to acquire weather information, for example, in the weather such as rain, snow, road ice, etc., the friction force generated between the vehicle and the deceleration strip is also different, and thus the vibration effect felt by the driver is also different when the vehicle passes through the deceleration strip.

In the present embodiment, when acquiring the vehicle-related information of the vehicle, any one or more of the above may be acquired, and the specific limitation is not made here.

S103, determining a first height value of the deceleration strip according to the predicted running speed and the vehicle associated information; the first height value is the height of the deceleration strip when the vehicle passes through the deceleration strip, and is larger than the initial height value of the deceleration strip.

For example, after the predicted running speed and the vehicle-related information are acquired, the height of the speed-reduction zone, that is, the first height value, when the vehicle runs through the speed-reduction zone may be determined based on the acquired vehicle-related information and the predicted running speed.

In one example, the electronic device may be preset with a plurality of trained models, where each trained model corresponds to a type selection of the vehicle-related information. After the vehicle-related information is acquired, first, the type of the selected model may be determined based on the type of information in the acquired vehicle-related information, and then the acquired vehicle-related information and the predicted travel speed are input into a preset model, and the determined first altitude value is output from the preset model.

S104, obtaining lifting height according to the first height value of the speed reducing belt and the second height value of the speed reducing belt; the second height value is the height value of the deceleration strip at the current time.

For example, after determining the first height value of the deceleration strip and the second height value representing the current height value of the deceleration strip, a height difference between the two, i.e. the lifting height of the deceleration strip, is determined. Here, the lifting height of the deceleration strip may be used to indicate the amount of change in the deceleration strip height,

S105, controlling the deceleration strip to reach a first height value according to the lifting height.

For example, after the electronic device determines the lifting height, the height of the deceleration strip may be further controlled to reach the first height value based on the lifting height. It should be noted that, the first height value of the present embodiment is greater than the initial height value of the deceleration strip. Wherein the initial height of the speed belt, i.e. the original height value of the speed belt, is not generated

It can be appreciated that in this embodiment, when it is determined that the predicted running speed of the vehicle is greater than the preset threshold, the height of the deceleration strip is raised to the first height value at this time, so as to enhance the shock feeling caused by the deceleration strip to the driver in the vehicle, so as to remind the user to decelerate. In addition, when determining the first height value corresponding to the deceleration strip when the vehicle passes through the deceleration strip, at this time, the first height value corresponding to the deceleration strip may be determined in combination with the vehicle-related information and the predicted running speed of the vehicle. The first height value determined by the method is more specific, and the deceleration reminding effect of the deceleration strip on the user can be more effective.

In one example, if the vehicle-related information includes current weight information and vehicle category information; in performing step S104, this may be achieved by:

In this embodiment, when the current weight information and the vehicle category information are included in the acquired vehicle-related information, at this time, the first altitude value corresponding to the currently acquired vehicle-related information and the predicted travel speed may be found based on the correspondence between the predicted travel speed, the current weight information, the vehicle category information, and the first altitude value stored in advance.

It can be appreciated that in this embodiment, when determining the first altitude value, the first altitude value may be found and determined based on the pre-stored correspondence among the predicted running speed, the current weight information, the vehicle category information, and the first altitude value, which is simpler. And the current weight information of the vehicle and the category information of the vehicle are also considered, so that the determined first height value can effectively remind a driver in the current vehicle, and the problem that effective reminding cannot be achieved for part of vehicles (such as vehicles with larger current weight or better damping effect of the vehicle) when the first height value is determined only based on the predicted running speed of the vehicle is avoided.

Fig. 2 is a flow chart of another deceleration prompt method based on deceleration strips according to an embodiment of the present application, as shown in fig. 2, the method includes the following steps:

s201, obtaining a predicted running speed of a vehicle passing through a deceleration strip; the predicted travel speed is a predicted speed at which the vehicle passes through the deceleration strip.

For example, this step may refer to step S101, which is not described herein. The execution body of the present embodiment will be described with reference to an electronic device as an example.

S202, if the predicted running speed is greater than a preset threshold value, acquiring current weight information of the vehicle, vehicle type information and shape information of a deceleration strip.

Illustratively, the vehicle-related information in the present embodiment includes current weight information of the vehicle, category information of the vehicle, and shape information of the deceleration strip.

The following steps S203 to S204 are repeated until a preset condition is reached: the preset condition is that a first stress value and a second stress value indicated by a stress analysis result are the same, the second stress value is a stress value determined based on a predicted running speed and a corresponding relation between the predicted running speed and the second stress value, and the predicted running speed and the second stress value are positively correlated.

S203, adjusting the value of the corresponding parameter of the current height value of the deceleration strip in the preset vehicle kinematic model to obtain the adjusted height value.

In this embodiment, a preset vehicle kinematic model may be pre-established in the electronic device, and the vehicle kinematic model may be used to analyze the stress situation of the vehicle during the driving process. In addition, the preset vehicle kinematic model in the embodiment includes the following input parameters: vehicle weight, vehicle category information, shape information of the speed bump, and height information of the speed bump. After the current weight information of the vehicle, the category information of the vehicle and the shape information of the deceleration strip are obtained in step S202, the parameters of the preset vehicle kinematic model can be modified through the above information, so that the vehicle driving scene simulated in the modified preset vehicle kinematic model is more similar to the real driving scene. And then, adjusting the value of a parameter corresponding to the current height of the deceleration strip in the preset vehicle kinematic model.

S204, taking the vehicle type information, the current weight information, the shape information of the deceleration strip, the adjusted height value and the predicted running speed as input of a preset vehicle kinematic model to obtain an output stress analysis result of the preset vehicle kinematic model, wherein the stress analysis result is used for indicating a first stress value of the vehicle in the longitudinal axis direction when the vehicle passes through the deceleration strip according to the predicted running speed, and the longitudinal axis direction is a direction perpendicular to a road surface where the deceleration strip is located.

Illustratively, the adjusted height value (i.e., the value of the parameter of the adjusted current height value of the deceleration strip), the current weight information of the vehicle, the vehicle type information, and the shape information of the deceleration strip obtained in step S202 are taken as input values of the preset vehicle kinematic model, and the stress condition (i.e., the first stress value) corresponding to the vehicle in the direction perpendicular to the road surface when the vehicle passes through the deceleration strip corresponding to the adjusted height value according to the predicted running speed is predicted by the model. It will be appreciated that the magnitude of the force applied by the vehicle in a direction perpendicular to the road surface is related to the shock experienced by the driver in the vehicle, the greater the magnitude of the force, the greater the shock experienced by the driver.

In addition, a correspondence relationship between the vehicle running speed and a second stress value is preset in the electronic device, wherein the second stress value is a stress value of the vehicle in a direction perpendicular to the road surface when the vehicle passes through the speed reduction zone according to the corresponding vehicle running speed. In addition, in the preset corresponding relation, the larger the running speed of the vehicle is, the larger the value of the second stress value corresponding to the vehicle-associated running speed is, so that a driver can be effectively reminded to control the vehicle to decelerate.

Therefore, after the preset vehicle kinematic model predicts the first stress value, the first stress value is further compared with the second stress value corresponding to the predicted vehicle running speed determined based on the preset relationship, and when the first stress value is different from the second stress value, the steps S202-S203 may be continuously repeated until the preset vehicle kinematic model outputs the first stress value identical to the second stress value. It should be noted that, the first stress value and the second stress value are the same, and the difference between the first stress value and the second stress value may be less than a preset threshold, which is not limited herein. In addition, when the height value corresponding to the parameter corresponding to the current height value of the deceleration strip in the preset vehicle kinematic model is adjusted, the value of the parameter can be adjusted according to the preset fixed variation each time, and the variation is not limited specifically.

S205, determining a first height value of the deceleration strip according to the adjusted height value, wherein the first height value is the height of the deceleration strip when the vehicle passes through the deceleration strip, and the first height value is larger than the initial height value of the deceleration strip.

For example, when the first stress value and the second stress value output by the preset vehicle kinematic model are the same, at this time, the first height value of the deceleration strip may be determined according to the adjusted height value input in the current preset vehicle kinematic model, for example, the adjusted height value input in the current preset vehicle kinematic model may be directly determined as the first height value of the deceleration strip, so as to achieve effective reminding for the vehicle driver.

It is understood that, in the present embodiment, a correspondence relationship between the vehicle running speed and the second stress value when the vehicle passes through the deceleration strip is preset in the electronic device, and in the correspondence relationship, the larger the running speed of the vehicle, the larger the corresponding second stress value. Further, when the vehicle speed is higher when the vehicle passes through the deceleration strip, the vibration felt by the driver in the vehicle is stronger, so that the driver can be effectively reminded of the reduction of the vehicle speed. In addition, in the embodiment, the preset vehicle kinematic model in the electronic device is related to the vehicle weight, the vehicle category, the shape information of the deceleration strip and the height of the deceleration strip, the stress value of the vehicle in the direction perpendicular to the road surface can be analyzed through the preset vehicle kinematic model, the first height value of the deceleration strip is further determined, the analysis result of the vehicle stress value obtained through the preset vehicle kinematic model is more accurate, and the determined first height value of the deceleration strip is further more accurate, so that the effectiveness of reminding the driver of deceleration is achieved.

In one example, the vehicle-associated information further includes: weather information; in performing step S205, this may be achieved by: determining a weight coefficient according to weather information; multiplying based on the weight coefficient and the adjusted height value to obtain a processed height; and determining the processed height as a first height value of the deceleration strip.

In this embodiment, the vehicle-related information in this embodiment further includes weather information based on the steps S202 to S205, where the weather information is used to indicate weather information corresponding to the environment where the deceleration strip is located. When the first height information of the deceleration strip is determined through the adjusted height value, at the moment, the weight coefficient corresponding to the weather information can be determined according to the weather information currently corresponding to the deceleration strip. It can be understood that in this embodiment, the correspondence relationship between the weather information and the weight coefficient may be preset in the electronic device, for example, when the weather information is raining, the weight coefficient is set to 0.9 in consideration of the influence factor of the road wet skid on the driving of the vehicle and ensuring the normal running of the vehicle. When the weather information is snowing, the weight coefficient may be set to 0.8 at this time. When weather information is sunny, the weight coefficient may be set to 1 at this time. And then, after determining the weight coefficient corresponding to the weather information of the current deceleration strip, multiplying the weight coefficient by the adjusted height value, and taking the multiplied result as the first height value of the deceleration strip. That is, the first height value corresponding to the adjusted height value in the case of rainy and snowy weather is smaller than the first height value corresponding to the adjusted height value in the case of sunny days.

It can be appreciated that in this embodiment, when the first height value corresponding to the deceleration strip is determined based on the adjusted height value, different weight coefficients may be set for different weather information, so as to ensure the running safety of the vehicle when passing through the deceleration strip in rainy and snowy weather.

S206, obtaining lifting height according to the first height value of the speed bump and the second height value of the speed bump; the second height value is the height value of the deceleration strip at the current time.

S207, controlling the deceleration strip to reach a first height value according to the lifting height.

For example, step S206 and step S207 may refer to step S104 and step S105, which are not described herein.

S208, acquiring a gravity value detected by a gravity sensor in the deceleration strip.

And S209, if the vehicle passes through the deceleration strip based on the gravity value detected by the gravity sensor, controlling the height of the deceleration strip to be reduced to the initial height.

In this embodiment, a gravity sensor is provided in the deceleration strip, and after the electronic device controls the deceleration strip to reach the first height value, it is possible to determine whether the vehicle passes through the deceleration strip by acquiring the gravity value detected by the gravity sensor in the deceleration strip. After determining that the vehicle passes the deceleration strip, the deceleration strip may be controlled to descend to an initial height value.

In one example, when determining whether the vehicle passes through the deceleration strip based on the gravity value detected by the gravity sensor, it may be determined by analyzing a change curve of the gravity value detected by the gravity sensor with time, and after a time point when the height of the deceleration strip is controlled to reach the first height value, if the gravity value detected by the gravity sensor is found to have a phenomenon of rising in value twice after the time point, the vehicle is considered to pass through the deceleration strip.

In one example, when the gravity sensors are provided in the deceleration strip, it is conceivable to provide a plurality of gravity sensors uniformly distributed in the deceleration strip.

It can be appreciated that in this embodiment, after the vehicle passes through the deceleration strip, the height value of the deceleration strip is also restored to the initial height of the deceleration strip, so as to reduce the power consumption of the device for adjusting the height of the deceleration strip in the deceleration strip.

In one example, in performing step S209, this may be achieved by: if it is determined that the gravity value detected by the gravity sensor has at least two maximum points in a preset time interval, determining that the vehicle passes through the deceleration strip, and controlling the height of the deceleration strip to be reduced to an initial height, wherein the preset time interval is determined based on the length of the vehicle and a preset threshold value.

In the present embodiment, it is possible to determine whether or not at least two maximum points have occurred within a preset time interval through the gravity value monitored by the gravity sensor when determining whether or not the vehicle passes through the deceleration strip. And, the preset time interval may be determined by the length of the vehicle and a preset threshold. It is understood that, since the predicted traveling speed of the vehicle is greater than the preset threshold value, the preset time interval determined based on the vehicle length of the vehicle and the preset threshold value at this time may be regarded as the maximum duration that the vehicle spends while passing through the deceleration strip. Therefore, when the first maximum point appears in the value of the gravity sensor, if at least two maximum points appear in a preset time interval including the moment corresponding to the first maximum point appear, the vehicle is considered to pass through the deceleration strip at the moment.

It can be appreciated that in this embodiment, by determining the preset time interval based on the vehicle length of the vehicle and the preset threshold value, and by determining whether there are two maximum points in the time interval, it is possible to more accurately determine whether the vehicle passes through the deceleration strip.

In this embodiment, a correspondence relationship between the vehicle travel speed and the second stress value when the vehicle passes through the deceleration strip is preset in the electronic device in this embodiment, and in this correspondence relationship, the larger the vehicle travel speed, the larger the second stress value. Further, when the vehicle speed is higher when the vehicle passes through the deceleration strip, the vibration felt by the driver in the vehicle is stronger, so that the driver can be effectively reminded of the reduction of the vehicle speed. In addition, in the embodiment, the vehicle kinematic model is preset in the electronic device and is related to the vehicle weight, the vehicle type, the shape information of the deceleration strip and the height of the deceleration strip, so that the analysis result of the vehicle stress value obtained through the preset vehicle kinematic model is more accurate, and the determined first height value of the deceleration strip is also more accurate, so that the effectiveness of reminding the driver of deceleration is achieved.

Fig. 3 is a flow chart of another deceleration prompt method based on deceleration strips according to an embodiment of the present application, as shown in fig. 3, the method includes the following steps:

s301, if the fact that the vehicle enters a preset range is determined, controlling a motor in a deceleration strip to rotate according to a preset rotating speed; wherein the preset range is positioned on the side of a preset direction of the speed bump, and the preset direction is opposite to the running direction of the vehicle; the deceleration strip includes: the speed reducing belt comprises a speed reducing belt body, a motor and a hydraulic mechanism.

Illustratively, in the present embodiment, a speed-reducing belt body, a motor, and a hydraulic mechanism are provided in the speed-reducing belt. Under the drive of energy generated by the rotation of the motor, the hydraulic mechanism can improve the height of the speed bump main body, and further the speed bump height is adjusted. In this step, in order to avoid that the height of the deceleration strip is not adjusted when the vehicle passes through the deceleration strip, in this embodiment, when the vehicle is detected to travel to the preset range, the motor in the deceleration strip may be controlled to rotate at the preset rotation speed in advance. The preset range is positioned on one side of the speed bump in a preset direction, and the preset direction is the opposite direction of the vehicle running. It should be noted that when the motor rotates at a predetermined rotational speed, the energy output by the motor rotation is insufficient to drive the hydraulic mechanism to change the current height of the speed-reducing belt.

S302, acquiring image information of a vehicle in a preset range and radar signals of the vehicle in the preset range; wherein the preset range is located on a predetermined direction side of the speed bump, the predetermined direction being a direction opposite to a traveling direction of the vehicle.

For example, in the present embodiment, in order to predict the predicted travel speed when the vehicle passes through the deceleration strip, the predicted travel speed when the vehicle passes through the deceleration strip may be predicted by acquiring image information of the vehicle in a preset range and a radar signal of the vehicle in the preset range.

In one example, the image signal and the radar signal may be acquired by providing a camera and a radar detection device in a road on which the vehicle is traveling. In addition, the preset range may be an intersection range of respective sensing ranges of the camera and the radar detection apparatus. For example, as shown in fig. 4, fig. 4 is a schematic view of an application scenario provided in the embodiment of the present application. In the figure, a camera and a radar detection device (for example, a laser radar) are provided on a road. The image information and the radar signal detected by the camera and the radar detection device can be sent to the electronic equipment, and then the electronic equipment further controls the height of the deceleration strip in the road after analyzing and processing based on the acquired image signal and radar signal.

S303, determining the acceleration of the vehicle in a preset range and the first vehicle speed when the vehicle leaves the preset range based on the image information and the radar signal.

In this embodiment, after acquiring the image information and the radar signal monitored when the vehicle travels within the preset range, the first vehicle speed corresponding to the vehicle when the vehicle leaves the preset range and the acceleration corresponding to the vehicle when the vehicle travels within the preset range are determined further based on the image information and the radar signal.

In one example, when the first vehicle speed is determined based on the image information and the radar signal, the vehicle position may be located in the image information based on the acquired radar signal at this time, and the first vehicle when the vehicle leaves the preset range and the acceleration when the vehicle travels within the preset range may be determined based on the vehicle position in the plurality of frames of image information in which the vehicle travels within the preset range.

In one example, when "determining acceleration of the vehicle within a preset range based on the image information and the radar signal" in step S303 is performed, this may be achieved by:

and a first step of determining second vehicle speeds corresponding to the moments one by one when the vehicle runs in a preset range based on the image information.

And a second step of determining a third vehicle speed corresponding to the moments one by one when the vehicle runs in a preset range based on the radar signal.

And thirdly, carrying out weighted summation processing on the second vehicle speed and the third vehicle speed at the same moment to obtain a fourth vehicle speed corresponding to the moments one by one.

And a fourth step of determining acceleration of the vehicle in a preset range based on a plurality of fourth vehicle speeds.

In the present embodiment, when determining the acceleration of the vehicle when traveling in the preset range based on the image information and the radar signal, first, the second vehicle speed at a plurality of times when the vehicle travels in the preset range may be determined based on the multi-frame image in the acquired image information when the vehicle travels in the preset range.

And, the third vehicle speed at a plurality of times when the vehicle is traveling in the preset range may be determined based on a plurality of signals among the acquired radar signals when the vehicle is traveling in the preset range.

And then, carrying out weighted summation processing on the second vehicle speed and the third vehicle speed at the same moment, and further obtaining a fourth vehicle speed at the same moment. The fourth vehicle speed at a plurality of times can be obtained by performing the above-described weighted sum processing for the vehicle speeds at each same time. In a possible case, when the weighted sum processing is performed on the second vehicle speed and the third vehicle speed at the same time, respective weight values of the second vehicle speed and the third vehicle speed at the weighted sum processing may be determined based on the current weather information, for example, when the photographed image information is blurred due to the weather influence, the weight value corresponding to the third vehicle speed may be set to be larger than the weight value corresponding to the second vehicle speed.

After determining the fourth vehicle speeds at a plurality of moments, the acceleration of the vehicle when traveling in the preset range can be further determined based on the plurality of fourth vehicle speeds and the moment corresponding to each fourth vehicle speed.

It can be appreciated that in this embodiment, when determining the acceleration, the second vehicle speed determined based on the image information and the third vehicle speed corresponding to the radar information may be weighted and summed, so as to improve the accuracy of the obtained acceleration and the accuracy of the finally predicted speed, so as to effectively slow down the vehicle.

S304, acquiring first position information of a preset range and second position information of a deceleration strip.

S305, determining a predicted running speed of the vehicle that is about to pass through the deceleration strip based on the acceleration, the first vehicle speed, the first position information, and the second position information.

For example, after the acceleration and the first speed of the vehicle are determined in step S303, the distance between the preset range and the deceleration strip may be determined by acquiring the first position information corresponding to the preset range and the second position information where the deceleration strip is located. Then, a predicted travel vehicle speed at which the predicted vehicle passes through the deceleration strip is estimated based on the determined distance, acceleration, and first vehicle speed.

It can be appreciated that in the present embodiment, when determining the predicted running speed of the vehicle, the acceleration of the vehicle in the preset range and the first vehicle speed corresponding to the vehicle leaving the preset range may be further determined based on the acquired image information and the radar signal, so as to avoid the problem that the determined predicted running speed is inaccurate if the acquired image information is unclear when determining the vehicle speed based on the image information only.

S306, if the predicted running speed is greater than a preset threshold value, acquiring vehicle-related information of the vehicle, and determining a first height value of the deceleration strip according to the predicted running speed and the vehicle-related information; the first height value is the height of the deceleration strip when the vehicle passes through the deceleration strip; the vehicle-related information includes one or more of the following: current weight information, vehicle category information, weather information, shape information of the speed bump, current height of the speed bump.

For example, the present step may refer to steps S102 and S103, which are not described herein.

S307, obtaining lifting height according to the first height value of the speed reducing belt and the second height value of the speed reducing belt; the second height value is the height value of the deceleration strip at the current time.

For example, this step may refer to step S104, which is not described herein.

And S308, adjusting the rotating speed of the motor according to the lifting height so that the hydraulic mechanism reaches the height of the speed reduction belt main body to a first height value under the control of the motor.

It can be understood that when the motor is controlled in advance to rotate according to the preset rotation speed and the height of the speed reduction belt is further required to be adjusted, the rotation speed of the motor can be adjusted through the determined lifting height at the moment, so that the hydraulic mechanism can adjust the height of the speed reduction belt main body by a first height value under the control of the motor. By the method for controlling the rotation of the motor in advance, the phenomenon that the motor is required to be started by additionally consuming time when the height reached by the speed reducing belt is required to be adjusted can be avoided, and the control efficiency of the height adjustment of the speed reducing belt is improved.
