[0024] Embodiment 1:

[0025] The inventors of the present application have found through analysis of bicycle accidents that even if a rider turns on the taillight of the bicycle, the taillight can only alert the vehicle behind the bicycle, but has no warning effect on the rider. In other words, the rider himself cannot feel whether there is danger behind the bicycle. Therefore, the solution of only installing a taillight on the bicycle still leads to a high probability of rear-end collision between the rider and the vehicle behind him.

[0026] In order to reduce the occurrence of rear-end collisions involving bicycles, an embodiment of the present application provides a reminder method, which is described below in conjunction with the accompanying drawings.

[0027] Figure 1 A flowchart of a reminder method provided by an embodiment of the present application is shown. The reminder method is applied to a bicycle. A controller is provided on the handlebar of the bicycle. The controller includes a reminder module and a first control module. A taillight device is provided on the body of the bicycle. The taillight device includes a sensor, a first reminder light and a second control module. The reminder method includes:

[0028] Step S11: The sensor detects the rear of the bicycle to obtain a corresponding sensing value.

[0029] The sensors of this embodiment include radar sensors and / or light sensors, and the detection direction of these sensors is the rear of the bicycle.

[0030] Step S12, the second control module obtains the sensing value, determines whether there is a vehicle behind the bicycle according to the sensing value, and sends a first turn-on command to the first prompt light and a first prompt message to the first control module when it is determined that there is a vehicle behind the bicycle.

[0031] The first warning light may be a light emitting diode (LED).

[0032] The first prompt information includes information for indicating that there is a vehicle behind the bicycle.

[0033] In some embodiments, the first control module and the second control module communicate wirelessly, such as by using a low-power wireless transmission protocol such as Bluetooth.

[0034] Step S13: After receiving the first start command, the first prompt light starts a flashing mode, where the flashing mode is used to indicate that the first prompt light flashes.

[0035] Specifically, the first indicator light flashes in a cyclic flashing manner of on, off, on, off, etc. It should be noted that each time the first indicator light is lit (i.e., the first indicator light is on), the corresponding color may be the same as or different from the color corresponding to the last time it was lit. For example, when the first indicator light is lit for the first time, the color displayed is red, then the first indicator light is off, and then the first indicator light is lit for the second time, and the color displayed is yellow, etc., and the flashing is repeated in this manner.

[0036] Step S14: the first control module sends a second opening command to the prompt module according to the first prompt information.

[0037] Step S15, the prompt module turns on a prompt mode after receiving the second start command, and the prompt mode instructs the prompt module to emit a sound and / or light prompt.

[0038] In the embodiment of the present application, when the second control module determines that there is a vehicle behind the bicycle, it notifies the first warning light in the taillight device to flash, and sends the first prompt information to the first control module, so that the first control module notifies the prompt module in the controller to issue a sound and / or light prompt. Since the taillight device is arranged on the body of the bicycle, the vehicle behind the bicycle can quickly know that there is a bicycle in front according to the flashing first warning light in the taillight device. At the same time, since the controller is located on the handlebar, the rider can quickly know that there is a vehicle behind according to the sound and / or light prompt issued by the prompt module in the controller. That is, the reminder method applied to the bicycle provided in the embodiment of the present application can not only remind the vehicle behind, but also remind the rider, thereby reducing the probability of the rider having a rear-end collision.

[0039] In some embodiments, the prompt module includes a second prompt light, and the prompt mode includes a flashing mode. Correspondingly, step S15 includes:

[0040] After receiving the second start command, the second warning light turns on the flashing mode, and the flashing mode is used to indicate that the second warning light flashes. Since the second warning light flashes, and the flashing mode is more attractive than the mode of only emitting light without flashing, therefore, the second warning light turns on the flashing mode to remind the rider, which is helpful for the rider to know more quickly that there is a vehicle behind.

[0041] In some embodiments, the prompt module includes a microphone, and the prompt mode includes a loop play mode. Correspondingly, step S15 includes:

[0042] The microphone starts a loop play mode after receiving the second start command, and the loop play mode is used to instruct the microphone to play the first prompt information in a loop.

[0043] Since the first prompt information includes information for indicating that there is a vehicle behind the bicycle, after the microphone plays the first prompt information in a loop, the rider can quickly know that there is a vehicle behind the bicycle without watching with the eyes.

[0044] In some embodiments, Figure 2 As shown, the taillight device is installed on the seat pillar. Since the seat pillar is close to the rear of the bicycle and is usually not removed maliciously (this is because after the seat pillar is removed, the bicycle will have no seat, which is inconvenient to ride), therefore, installing the taillight device on the seat pillar can not only effectively detect the rear of the bicycle, but also help to ensure the safety of the taillight device.

[0045] In some embodiments, the sensor includes a radar sensor, the sensing value includes point cloud data, and correspondingly, judging whether there is a vehicle behind the bicycle according to the sensing value includes:

[0046] A1. Determine whether the point cloud data includes an object. If an object is included, determine the attribute of the object according to the point cloud data. The attribute includes at least one of the following: shape, speed, and orientation.

[0047] A2. If the attribute of the object meets the preset radar attribute conditions, it is determined that there is a vehicle behind the bicycle; otherwise, it is determined that there is no vehicle behind the bicycle.

[0048] For example, when it is determined that the shape of the object is that of a vehicle, the speed of the object is greater than a preset speed threshold, and the direction is directly behind a bicycle, it is determined that the shape, speed, and direction of the object all meet the preset radar attribute conditions, that is, it is determined that there is a vehicle behind the bicycle.

[0049] In an embodiment of the present application, the second control module obtains point cloud data at multiple times from the radar sensor, and identifies the obtained point cloud data through a preset object recognition algorithm (such as the Second object recognition algorithm), and then can identify the shape of the object included in the point cloud data. At the same time, since the point cloud data itself contains position information, the relative position (i.e., orientation) of the object and the bicycle can be determined based on the point cloud data. In addition, after obtaining the position information of the object at different times from the point cloud data corresponding to the object, the speed of the object can be calculated based on the position information at different times. Since the shape, speed and / or orientation of the object may affect whether the bicycle has a rear-end collision, therefore, only when the attributes of the object meet the preset radar attribute conditions, it is determined that there is a vehicle behind the bicycle, which can improve the accuracy of the judgment result, and thus can improve the accuracy of the reminder.

[0050] In some embodiments, the taillight device further includes a buzzer.

[0051] When the second control module determines that there is a vehicle behind the bicycle, the second control module sends a third turn-on command to the buzzer, and the buzzer makes a sound after receiving the third turn-on command.

[0052] In the embodiment of the present application, since the second control module also notifies the buzzer in the taillight device to make a sound, it can further remind the vehicles and riders behind.

[0053] In some embodiments, if the third start command also includes information indicating the distance between the bicycle and the vehicle behind, the buzzer adjusts the volume value according to the distance information. When the distance value contained in the distance information is smaller, the corresponding volume value is larger, and vice versa, the corresponding volume value is smaller, and the sound is emitted according to the adjusted volume value. Since the volume value is inversely proportional to the distance value, the rider can judge the distance between the vehicle and the bicycle according to the volume of the sound emitted by the buzzer, thereby more effectively reducing the probability of rear-end collision accidents.

[0054] In some embodiments, considering that the relative position of the bicycle and the vehicle behind it may change, the reminder to the rider and the vehicle behind it also needs to change. That is, after sending the first turn-on command to the first warning light and sending the first warning information to the first control module, it also includes:

[0055] B1. If the second control module determines that there is no vehicle behind the bicycle according to the newly acquired sensing value, a first closing command is sent to the first warning light, and a second warning message is sent to the first control module.

[0056] B2. The first prompt light turns off the flashing mode after receiving the first turn-off command.

[0057] B3. The first control module sends a second closing command to the prompt module according to the second prompt information.

[0058] B4. The prompt module turns off the prompt mode after receiving the second turn-off command.

[0059] In an embodiment of the present application, when the first prompt light turns on the flashing mode and the prompt module turns on the prompt mode, if the second control module determines that there is no longer a vehicle behind the bicycle based on the newly acquired sensing value, it notifies the first prompt light to turn off the flashing mode, and notifies the prompt module to turn off the prompt module through the first control module, thereby avoiding interference of the first prompt light and the prompt module to the rider.

[0060] In some embodiments, the taillight device further includes a positioning module.

[0061] C1. The positioning module obtains the positioning information of the bicycle. Specifically, the positioning module may be a global positioning system (GPS) module, and the GPS module is used to continuously obtain the positioning information of the bicycle.

[0062] C2. The second control module obtains the positioning information, and determines whether the bicycle moves according to the positioning information. If it is determined that the bicycle moves, a movement prompt is sent to a designated user terminal device, where the movement prompt is used to indicate that the bicycle moves.

[0063] In the embodiment of the present application, the positioning module sends the positioning information it obtains to the second control module, and the second control module compares the two positioning information obtained at adjacent times. If it is determined that the two positioning information are different, it is determined that the bicycle has moved, and a movement prompt is sent to the designated user terminal device. Since the movement prompt is used to indicate that the bicycle has moved, the user can quickly know whether the bicycle has moved through the designated user terminal device.

[0064] In some embodiments, if the taillight device includes a buzzer, the reminder method further includes:

[0065] D1. If the second control module determines that the bicycle moves, a third opening command is sent to the buzzer.

[0066] D2. The buzzer makes a sound after receiving the third opening command.

[0067] D3. If the second control module receives the alarm cancellation instruction sent by the designated user terminal device, it sends a third closing command to the buzzer.

[0068] Specifically, the taillight device can communicate with the controller and the designated user terminal device respectively, and the communication method is as follows: Figure 3 shown.

[0069] When the designated user terminal device receives the movement prompt, a button for cancelling the alarm may be displayed on the interface of the designated user terminal device. When the user clicks the button for cancelling the alarm, the designated user terminal device will send an alarm canceling instruction to the second control module.

[0070] D4. The buzzer stops making sound after receiving the third closing command.

[0071] In the embodiment of the present application, since the sound propagation distance is relatively long, after the second control module determines that the bicycle has moved, the buzzer is notified to sound an alarm, so that the user can know that the bicycle has been moved even at a relatively long distance. In addition, since the user can cancel the alarm through the designated user terminal device, when the user moves the bicycle by himself, the buzzer can be notified to stop sounding, so that the user will not be disturbed by the buzzer.

[0072] In some embodiments, the taillight device further includes an anti-tampering sensor. The reminder method further includes:

[0073] E1. The anti-disassembly sensor is used to detect whether the tail light device is displaced, and after detecting that the tail light device is displaced, sends displacement information to the second control module.

[0074] Specifically, the anti-tampering sensor can determine whether the taillight device is displaced by comparing its position on the taillight device at different times.

[0075] E2. After receiving the displacement information, the second control module determines whether an anti-dismantling release instruction sent by a designated user-end device is received. If the anti-dismantling release instruction is not received, a first turn-on command is sent to the first prompt light, and abnormal information is sent to the designated user-end device, wherein the anti-dismantling release instruction includes information agreeing to dismantle the taillight device, and the abnormal information includes information indicating that the taillight device has been dismantled.

[0076] Specifically, after the designated user terminal device receives the displacement information, a prompt may be displayed on the interface of the designated user terminal device asking whether to agree to remove the taillight device, and an agree button and a reject button may be displayed. When the user clicks the agree button, the designated user terminal device will receive the anti-removal instruction and send the anti-removal instruction to the second control module.

[0077] E3. The first prompt light turns on the flashing mode after receiving the first turn-on command.

[0078] In the embodiment of the present application, since the second control module can select whether to notify the first prompt light to turn on the flashing mode according to the displacement information sent by the anti-disassembly sensor and the judgment result of whether the anti-disassembly release command sent by the designated user terminal device is received, the accuracy of the notification can be improved. For example, if the tail light device is dismantled without the user's knowledge, a timely reminder can be issued.

[0079] In some embodiments, the taillight device further includes an axis sensor, which may be a six-axis sensor. At this time, the reminder method further includes:

[0080] F1. The shaft sensor is used to detect change information, and the change information is used to indicate the change of the movement speed of the bicycle.

[0081] Specifically, when the bicycle is in motion, the axle sensor will be able to detect the changing information of the bicycle.

[0082] F2. The second control module obtains the change information, determines the change range of the bicycle according to the change information, and sends a first turn-on command to the first prompt light if the change range is greater than a preset range threshold.

[0083] Specifically, the second control module calculates the change amplitude of the bicycle according to the change information within a unit time, and compares the change amplitude with a preset amplitude threshold. If the change amplitude is greater than the preset amplitude threshold, a first turn-on command is sent to the first prompt light.

[0084] F3. The first prompt light turns on the flashing mode after receiving the first turn-on command.

[0085] In the embodiment of the present application, since the change range of the bicycle is usually large when the bicycle brakes or stops suddenly, when the second control module determines that the change range of the bicycle is large, it notifies the first prompt light to turn on the flashing mode, so as to timely warn the vehicles behind the bicycle.

[0086] In some embodiments, the controller further includes a left button and a right button, and the first prompt light includes a left light and a right light. Then the reminder method of the embodiment of the present application further includes:

[0087] G1. After detecting that the left key or the right key is pressed, the first control module sends steering information to the second control module, where the steering information indicates that the left key is pressed or indicates that the right key is pressed.

[0088] Specifically, if the left key is pressed, the turn information indicates that the left key is pressed.

[0089] G2. The second control module sends a fourth turn-on command to the first warning light module according to the turn information, and the fourth turn-on command is used to instruct the first warning light to turn on the left light or the right light.

[0090] Specifically, when the turn information indicates that the left key is pressed, the fourth turn-on command is used to instruct the first prompt light to turn on the left light.

[0091] G3. If the fourth turn-on command instructs the first prompt light to turn on the left light, the first prompt light turns on the left light after receiving the fourth turn-on command; if the fourth turn-on command instructs the first prompt light to turn on the right light, the first prompt light turns on the right light after receiving the fourth turn-on command.

[0092] In the embodiment of the present application, when the left button is pressed, the first prompt light turns on the left light, that is, the light on the left side lights up, and when the right button is pressed, the first prompt light turns on the right light, that is, the light on the right side lights up. Since when the user presses the left button (or the right button), it indicates that the rider will ride to the left, therefore, the light on the left (or right) side is helpful for the vehicle behind the bicycle to predict the riding direction of the bicycle in advance, thereby further reducing the probability of rear-end collision accidents.

[0093] In some embodiments, the controller further includes a help button, and the reminder method of the embodiment of the present application further includes:

[0094] H1. After the first control module detects that the help button is pressed, it sends a help message to the second control module.

[0095] The help button can be set between the left button and the right button.

[0096] H2. After receiving the distress message, the second control module sends a first turn-on command to the first prompt light, and sends a distress message to the target terminal, where the distress message includes the positioning information of the bicycle.

[0097] In some embodiments, after receiving the distress message, the second control module may also send a third turn-on command to the buzzer, and the buzzer emits a sound after receiving the third turn-on command.

[0098] H3. The first prompt light turns on the flashing mode after receiving the first turn-on command.

[0099] In some embodiments, after receiving the distress message, the second control module also sends a flashing frequency to the first warning light so that the first warning light flashes according to the flashing frequency. For example, the first warning light flashes in a cycle according to the frequency of three short, three long, three short, three long..., that is, flashes according to international conventions, so that others can more easily determine that the signal sent by the rider is a distress signal.

[0100] In the embodiment of the present application, since the rider may encounter an emergency during riding, and the help button is set in the controller, it is convenient for the rider to quickly send a help message. In addition, after the help message is sent, the first prompt light turns on the flashing mode and the user can also receive the help message through the target terminal (such as the terminal corresponding to the rescue platform), and the help message includes the location information of the bicycle. Therefore, on the one hand, it can timely remind the vehicle behind, and on the other hand, it can also notify the user that the rider wants to notify, so as to help the rider in time.

[0101] In some embodiments, Figure 4 As shown, the controller further includes a gyroscope, which is used to obtain the orientation change information of the bicycle. At this time, the first control module can judge whether the rider will ride to the left or the right according to the orientation change information obtained by the gyroscope, generate steering information according to the judgment result, and send the steering information to the second control module, so that the second controller module sends the fourth turn-on command to the first prompt light module according to the steering information.

[0102] In some embodiments, Figure 5 As shown, the sensor of the taillight device includes a light sensor. The light sensor is used to detect the brightness of the position where the light sensor is located, and the reminder method also includes:

[0103] The second control module obtains the brightness value detected by the light sensor, and sends a fifth turn-on command to the first prompt light if it is determined that the brightness value is less than a preset brightness threshold.

[0104] The first prompt light turns on a normal mode after receiving the fifth turn-on command, and the normal mode is used to indicate that the first prompt light only emits light but does not flash.

[0105] In the embodiment of the present application, when the brightness value is small, it indicates that the bicycle may be ridden at night. At this time, the first prompt light is notified to light up, which is helpful for vehicles behind the bicycle to detect the bicycle, thereby reducing the probability of rear-end collision accidents.
