The image acquisition device can be used for gathering image data, and the image acquisition device can be camera, camera and video recorder etc. and the image data that the image acquisition device gathered can be color image data also can be gray image data, and the image data that the image acquisition device gathered can be ordinary image data also can be wide-angle image data, and this application embodiment does not do the restriction to image acquisition device and image data. The ranging device may be used to measure range data, the ranging device may be a sensor and radar (e.g., microwave radar, millimeter wave radar, etc.), and the like. The distance measuring device and the distance data are not limited in the embodiment of the application. Since the tail light is disposed at the rear of the electric bicycle and is disposed to face rearward, the above image data may be used to represent an image of the rear of the electric bicycle, and the distance data may be used to indicate the distance of other traffic participants from the electric bicycle. Based on the image data and the distance data, the road condition data collected by the integrated tail lamp comprise the image data and the distance data. Of course, the road condition data may also include other data, such as the acquisition time, which is not limited in this embodiment of the present application.

In this embodiment of the present application, a communication line may be disposed between the integrated tail light and the ECU, and the communication manner may refer to the communication manner of the ECU and other components (such as a display screen, etc.) in the electric bicycle, which is not described herein.
The electronic control unit can be used for receiving road condition data; real-time processing is carried out on the road condition data to obtain a real-time processing result; and under the condition that the electric bicycle turns, sending prompt information according to the real-time processing result. Wherein, the real-time processing result can be used for representing that the turning is allowed currently or not allowed currently, and the prompt information can be used for informing the rider whether the turning can be performed. It can be appreciated that in the case where the real-time processing results characterize the current allowable turns, the prompt message can be used to inform the rider that the turn is possible; in the case where the real-time processing results indicate that turning is not currently allowed, the prompt message may be used to inform the rider that turning is not possible. The processing procedure of the electronic control unit for the road condition data will be described in detail later with reference to fig. 3, and will not be described again here.

It should be noted that, the frequency of collecting the road condition information, the frequency of reporting the road condition information, and the frequency of processing the road condition information by the electronic control unit may be set according to the needs, which is not limited in the embodiment of the present application. It can be understood that the higher the frequency is, the higher the real-time performance of the obtained real-time processing result is, the closer the real-time processing result is to the road condition when the electric bicycle turns, the higher the accuracy is, and therefore the higher the safety is.
Based on the electric bicycle turning auxiliary system, after the whole electric bicycle is electrified, the integrated tail lamp collects road condition data, and the road condition data are communicated with the electronic control unit in real time through the driving control unit, so that the road condition data are uploaded to the electronic control unit in real time.

In one embodiment, fig. 3 is a schematic flow chart of an electric bicycle turning assistance method provided in an embodiment of the present application. As shown in fig. 3, the electronic control unit in fig. 2 is taken as an example to illustrate that the method includes the following steps:
step S301, receiving road condition data reported in real time by an integrated tail lamp of the electric bicycle.
The integrated tail lamp of electric bicycle sets up in the afterbody of electric bicycle and face backward. The integrated tail lamp can collect road condition data in real time and report the road condition data to the electronic control unit in real time. The road condition data can be used for indicating the road condition behind the electric bicycle. In one possible implementation, the integrated tail light includes an image acquisition device for acquiring image data representing an image behind the electric bicycle and a ranging device for measuring distance data indicating the distance of other traffic participants from the electric bicycle. Accordingly, the road condition data may include the image data and the distance data.
Step S302, the road condition data is processed in real time to obtain a real-time processing result.
Wherein the real-time processing results can be used to characterize a currently allowed turn or a currently not allowed turn.
In one possible implementation, step S302 may include: determining individual traffic participants behind the electric bicycle from the image data; determining the distance between each traffic participant and the electric bicycle according to the distance data; obtaining a real-time processing result for characterizing allowed turns in the case that the distance between each of the individual traffic participants and the electric bicycle is greater than or equal to a first threshold; in the case where the distance between any one of the individual traffic participants and the electric bicycle is smaller than the first threshold value, a real-time processing result representing that turning is not allowed is obtained.
After the electronic control unit receives the road condition data, it can determine which traffic participants exist behind according to the image data, and can determine the distance between the traffic participants and the electric bicycle according to the distance data. The electronic control unit may then traverse the determined individual traffic participants and determine a magnitude relationship between the distance of each traffic participant from the electric bicycle and the first threshold.
If the distances between all the traffic participants and the electric bicycle are greater than or equal to the first threshold value, the situation that the traffic participants behind the electric bicycle are far away is indicated, and the possibility of collision when the electric bicycle turns at the moment is low, so that the electronic control unit can obtain a real-time processing result representing the current allowable turning.
If the distance between one or more of the traffic participants and the electric bicycle is smaller than a first threshold value, the traffic participants behind the electric bicycle are indicated to be close to the electric bicycle, and the possibility of collision when the electric bicycle is converted at the moment is higher, so that the electronic control unit can obtain a real-time processing result representing that turning is not allowed currently.
The first threshold may be set as needed. The greater the first threshold, the greater the safety, and the lesser the first threshold, the greater the probability that the rider may turn. The safety and the cornering potential can be balanced by adjusting the first threshold. The first threshold may set a plurality of values. Optionally, different first thresholds are selected for different types of traffic participants to determine. For example, a smaller first threshold may be selected for pedestrians and a larger first threshold may be selected for automobiles. Optionally, for different scenes, different first thresholds may be selected for determining. For example, a smaller first threshold may be selected for congested road segments and a larger first threshold may be selected for high-speed travel road segments.
In one possible implementation, the electronic control unit is provided on a riser connected to a handlebar in the electric bicycle, the electronic control unit comprising a gyroscope. The electronic control unit can acquire the rotation angle of the handlebar in real time through the gyroscope; and determining that the electric bicycle turns when the rotation angle is greater than a second threshold.
Because the electronic control unit is arranged on the vertical pipe connected with the handlebar, the handlebar rotates to drive the electronic control unit to rotate. Based on this, when the gyroscope in the electronic control unit detects that the electronic control unit rotates, the handle bar is rotated, which indicates that the rider needs to turn.
The second threshold may be used to determine whether the handlebar rotation angle reaches the degree of turning. When the angle of rotation is greater than the second threshold, indicating that the rider wants to turn, the electric bicycle can be determined to turn. When the rotation angle is smaller than or equal to the second threshold value, the user is indicated to have no turning intention, and only the rotation of the handle bar in the normal riding process can determine that the electric bicycle does not turn. The second threshold may be set as desired. The second threshold is smaller, the sensitivity is higher, but errors may occur. Alternatively, the electronic control unit may collect historical habit data of the rider to determine the second threshold. For example, the rider is riding more stably, and the second threshold may be suitably adjusted down; conversely, the second threshold may be appropriately adjusted.
Step S303, sending prompt information according to the real-time processing result under the condition that the electric bicycle turns.
Wherein, the prompt message can be used for informing the rider whether the rider can turn. The prompt information can be voice prompt information, text prompt information or image prompt information, etc. It can be appreciated that in the case where the real-time processing results characterize the current allowable turns, the prompt message can be used to inform the rider that the turn is possible; in the case where the real-time processing results indicate that turning is not currently allowed, the prompt message may be used to inform the rider that turning is not possible.
According to the electric bicycle turning auxiliary method, whether the turning is allowed currently or not is determined through the road condition data reported by the integrated tail lamp, and then the rider is informed of whether the turning can be performed or not by sending the prompt information under the condition of turning of the electric bicycle, so that the effect of assisting the rider in knowing the surrounding road conditions is achieved, traffic accidents caused by turning are reduced, turning safety is improved, and potential safety hazards are reduced.
In one possible implementation, step S303 may include: under the condition that the electric bicycle turns, if the real-time processing result represents that turning is not allowed, first prompt information is sent to a loudspeaker of the electric bicycle, and the first prompt information is used for indicating that voice prompts that the road condition behind the electric bicycle does not allow turning. Reference may be made specifically to the above-mentioned electric single difference turning auxiliary system, and details are not repeated here.
In one possible implementation, step S303 may include: and under the condition that the electric bicycle turns, if the real-time processing result indicates that turning is not allowed, sending second prompt information to a display screen of the electric bicycle, wherein the second prompt information is used for indicating and highlighting that the road condition behind the electric bicycle does not allow turning. Reference may be made specifically to the above-mentioned electric single difference turning auxiliary system, and details are not repeated here.
In one possible implementation, step S303 may include: and under the condition that the electric bicycle turns, if the real-time processing result represents that turning is allowed, sending third prompt information to a display screen of the electric bicycle, wherein the third prompt information is used for indicating and highlighting the road condition behind to allow turning. Reference may be made specifically to the above-mentioned electric single difference turning auxiliary system, and details are not repeated here.
In this application embodiment, through pronunciation and image broadcast, remind the person of riding whether can turn, effectively promoted the security.

The steps are not strictly limited to the order of execution unless explicitly recited herein, and the steps may be executed in other orders.
