Description

Bicycle driving safety warning system

This novel invention provides a bicycle travel safety warning system.

CN107839797A discloses a bicycle safety restricted zone system, including one or more projection and sensing devices and a processing unit. The projection and sensing device can detect vehicles near the bicycle and can project at least a portion of a visual safety restricted zone on the ground around the bicycle. The processing unit communicates with the projection and sensing device. When the projection and sensing device detects a vehicle near the bicycle, the processing unit generates an alarm that can be perceived by the bicycle user, and the projection and sensing device changes the visual appearance of the visual safety restricted zone.

Although the aforementioned visual safety restricted area can produce visual changes in appearance, the changes in the visual safety restricted area do not take into account the status of the oncoming vehicle, and cannot enable the rider to clearly understand the status of the oncoming vehicle. The aforementioned implementation method can actually only provide oncoming vehicle reminders. In addition, the aforementioned implementation scheme cannot be linked with other light equipment on the bicycle (such as turn signals).

The main purpose of this new model is to solve the problems existing in the implementation of the application.

To achieve the above-mentioned purpose, the present invention provides a bicycle travel safety warning system, which is implemented on a bicycle. The bicycle travel safety warning system includes an approaching vehicle sensing unit, a direction prompting unit, a projection warning unit and a control unit. The approaching vehicle sensing unit is configured on the bicycle. When the approaching vehicle sensing unit is activated, it provides an approaching vehicle signal, and the approaching vehicle signal includes the position relationship between the own vehicle and a neighboring vehicle and the speed of the neighboring vehicle. The direction prompting unit is configured on the bicycle and is controlled to generate a direction light. The projection warning unit includes at least two projection lamps facing different positions. When the at least two projection lamps are activated, a projection image is generated around the bicycle. The control unit is connected to the vehicle sensing unit, the direction prompting unit and the projection warning unit. The control unit has a first state for controlling the projection warning unit based on the vehicle signal, and a second state for controlling the projection warning unit based on the vehicle signal and the operation of the direction prompting unit. The control unit determines the speed of the neighboring vehicle in the vehicle signal based on a speed condition, and the control unit enters the first state when the speed condition is met.

In one embodiment, the control unit determines the warning state of the projection warning unit based on the speed of the neighboring vehicle in the oncoming vehicle signal.

In one embodiment, the bicycle travel safety warning system includes a wireless communication unit connected to the control unit.

In one embodiment, the control unit is connected to a controller that controls the direction prompt unit.

In one embodiment, the vehicle sensing unit includes the radar components, and the control unit determines the activation of at least one of the radar components based on the controller's control of the direction prompt unit.

In one embodiment, the bicycle travel safety warning system includes a front light unit connected to the control unit, and the front light unit performs light filling in the corresponding direction based on a direction light control signal issued by the controller.

Through the above implementation of the new model, compared with the conventional one, the following features are provided: the bicycle safety warning system of the new model not only generates the projection image according to the neighboring vehicle, but also provides the projection image according to the turning status of the bicycle. The new model uses the projection image to warn the rider, solving the accident caused by the rider needing to look back to confirm the oncoming vehicle, effectively reducing the accidental collision with the rear vehicle, and greatly increasing the safety of bicycle sports. In addition to reminding the rider of the oncoming vehicle, the projection image of the new model can also remind the driver of the neighboring vehicle to pay attention.

The detailed description and technical content of this new model are now described as follows with accompanying diagrams:

Please refer to FIG. 1 and FIG. 2 . The present invention provides a bicycle travel safety warning system 20, which is implemented on a bicycle 30. The bicycle travel safety warning system 20 includes an oncoming vehicle sensing unit 21, a direction prompting unit 22, a projection warning unit 23 and a control unit 24. The oncoming vehicle sensing unit 21 can be at least one radar component 211 or an ultrasonic sensing device or a camera module. The oncoming vehicle sensing unit 21 is configured on the bicycle 30. The oncoming vehicle sensing unit 21 senses at the rear of the bicycle 30. The oncoming vehicle sensing unit 21 can be combined with a taillight or a direction light 33, or independently set on a cargo rack or a rear wheel frame, but the present invention is not limited to this. When the oncoming vehicle sensing unit 21 is activated, it senses whether there is an oncoming vehicle approaching from behind the vehicle. When the vehicle sensing unit 21 is activated, it provides a vehicle signal 212, which includes the position relationship between the vehicle and a neighboring vehicle 40 and the speed of the neighboring vehicle 40. The aforementioned position relationship describes whether the neighboring vehicle 40 (i.e., the vehicle coming from behind) is approaching from the left or right side of the bicycle 30. The aforementioned speed of the neighboring vehicle 40 can be estimated by a calculation program in a calculation element included in the vehicle sensing unit 21, or estimated by the control unit 24 from the data provided by the vehicle sensing unit 21.

Furthermore, the direction prompting unit 22 is disposed on the bicycle 30, and the direction prompting unit 22 is the direction light 33 disposed on the bicycle 30. The direction prompting unit 22 is controlled to generate a direction light signal, and the direction prompting unit 22 can be controlled by a controller 31, and the controller 31 can be an independent electronic device, or a bicycle meter, or a smart phone. Furthermore, the projection warning unit 23 includes at least two projection lamps 231 facing different positions, and the at least two projection lamps 231 are both disposed on the bicycle 30. The at least two projection lamps 231 can be a laser lamp or other lamps that can generate obvious images on the ground. In one embodiment, the at least two projection lamps 231 are disposed on the two handlebars 301 of the bicycle 30, and the at least two projection lamps 231 can be designed to be disposed on the handlebars 301 in the shape of a handlebar plug 232. Each of the at least two projection lamps 231 will generate a projection image 50 around the bicycle 30 when it is activated. Each of the at least two projection lamps 231 provides the projection image 50 based on its own stored projection settings. The projection image 50 of each of the at least two projection lamps 231 is not limited to a single one, but can be adjusted according to the implementation. Furthermore, the projection image 50 can be adjusted in brightness and range according to the current environment. For example, during the day, the brightness of the projection image 50 increases and the projection range becomes smaller. At night, the brightness of the projection image 50 gradually decreases and the projection range becomes larger. Furthermore, the control unit 24 is connected to the vehicle sensing unit 21, the direction prompting unit 22 and the projection warning unit 23. The control unit 24 can be integrated with the aforementioned controller 31 into a single device, or implemented as a smart phone, or as an independent electronic device. In one embodiment, the control unit 24 is informationally connected to the controller 31 to obtain a signal for controlling the direction prompting unit 22 through the controller 31.

The new vehicle sensing unit 21, the direction prompting unit 22, the projection warning unit 23 and the control unit 24 can communicate wirelessly or wired, and are not limited to all wireless connections or all wired connections. The aforementioned wireless communication can be ANT+ wireless transmission protocol or Bluetooth wireless transmission protocol, and the aforementioned wired communication can be CAN wired communication protocol and UART wired communication protocol.

As mentioned above, the control unit 24 of the present invention has a first state for controlling the projection warning unit 23 based on the vehicle signal 212, and a second state for controlling the projection warning unit 23 based on the vehicle signal 212 and the operation of the direction prompt unit 22. The implementation environment of the control unit 24 in the first state is that the bicycle 30 is moving and there is an oncoming vehicle approaching from behind, as shown in FIG3 . In the aforementioned implementation environment, the oncoming vehicle sensing unit 21 is activated to sense whether there is an oncoming vehicle approaching the rear of the bicycle 30. When the neighboring vehicle 40 enters the sensing range of the oncoming vehicle sensing unit 21, the oncoming vehicle sensing unit 21 senses the speed of the neighboring vehicle 40 and further senses the position of the neighboring vehicle 40. The control unit 24 receives the vehicle signal 212 provided by the vehicle sensing unit 21, that is, adjusts the operation of the projection warning unit 23 based on the vehicle signal 212, and the generation of the projection image 50 assists the rider of the bicycle 30 to understand the surrounding vehicle conditions. Further, the control unit 24 determines the speed of the neighboring vehicle 40 in the vehicle signal 212 with a speed condition, and the control unit 24 enters the first state when the speed condition is met. In this embodiment, the first state is based on whether the neighboring vehicle 40 is approaching at a high speed. The high speed is based on the speed condition. When the speed of the neighboring vehicle 40 exceeds the speed condition, it is considered to be a high speed. The speed condition can be 40 or 50 per hour, but it is not the above example.

The implementation environment of the control unit 24 in the second state is when the direction prompt unit 22 is activated while the bicycle 30 is traveling, and a vehicle is approaching from behind, as shown in Figures 4 and 5. In the aforementioned implementation environment, after the vehicle sensing unit 21 is activated, the rider of the bicycle 30 wants to change lanes or change the traveling position, which triggers the direction prompt unit 22 to generate the direction light. The vehicle sensing unit 21 senses the approach of the neighboring vehicle 40, and the control unit 24 controls the projection warning unit 23 to generate the projection image 50 based on the sensing result of the vehicle sensing unit 21 and the operation of the direction prompt unit 22, and the projection image 50 generated here may be different from the projection image 50 generated when the control unit 24 is in the first state.

The new invention uses the projected image to warn the rider, solving the problem of the rider having to look back to confirm the oncoming vehicle, and can effectively reduce the possibility of accidents such as rear-end collisions, greatly increasing the safety of cycling. In addition to reminding the rider of the oncoming vehicle, the projected image 50 can also remind the driver of the nearby vehicle 40 to pay attention.

In one embodiment, the control unit 24 can also determine the warning state of the projection warning unit 23 based on the speed of the neighboring vehicle 40 in the approaching vehicle signal 212. For example, the control unit 24 determines the flickering frequency of the projected image based on the speed of the neighboring vehicle 40. When the speed of the neighboring vehicle 40 is slower, the projected image is presented with a slower flickering frequency, and when the speed of the neighboring vehicle 40 is faster, the projected image is presented with a faster flickering frequency. In addition to the aforementioned flickering frequency, the brightness of the projected image or the image content of the projected image can also be adjusted.

Referring again to FIG. 1 , in one embodiment, the vehicle sensing unit 21 includes a plurality of radar components 211, and the radar components 211 are used to sense vehicles coming from different directions, and the different directions refer to the right side and the left side of the rear of the bicycle 30. When the sensing ranges of the radar components 211 overlap, the electronic design of the vehicle sensing unit 21 will perform weight analysis based on the signals generated by the radar components 211 to determine the position of the neighboring vehicle 40. In one embodiment, the control unit 24 determines the activation of at least one of the radar components 211 based on the control of the direction prompt unit 22 by the controller 31. To further explain, when the direction indicator signal generated by the direction prompt unit 22 indicates a left turn, the control unit 24 controls one of the radar components 211 located on the left side. Similarly, when the direction indicator signal generated by the direction prompt unit 22 indicates a right turn, the control unit 24 controls one of the radar components 211 located on the right side.

Referring again to FIGS. 4 to 6 , in one embodiment, the bicycle travel safety warning system 20 includes a front fill light unit 25 connected to the control unit 24. The front fill light unit 25 may be two fill lights 251 mounted on the front of the bicycle 30, and the two fill lights 251 are respectively directed to the left and right sides of the bicycle 30. It should be understood that the two fill lights 251 are different from the one front light 32 of the bicycle 30, and each of the two fill lights 251 of the front fill light unit 25 is activated only when the bicycle 30 is turning. Furthermore, the front fill light unit 25 performs fill light in the corresponding direction based on a direction light control signal 311 sent by the controller 31 to the direction prompt unit 22. Specifically, when the direction light is a right turn, the right side of the two fill lights 251 is activated to perform fill light. Similarly, when the direction light is a left turn, the left side of the two fill lights 251 is activated to perform fill light.

Please refer to Figures 7 and 8 again. In one embodiment, the bicycle travel safety warning system 20 includes a wireless communication unit 26 connected to the control unit 24. The wireless communication unit 26 links the bicycle travel safety warning system 20 with at least one light device on another bicycle 34 to increase the safety of the convoy. The aforementioned light device can be a direction light 341 or a projection light 342. Furthermore, the bicycle 34 can also be equipped with the bicycle travel safety warning system 20, and the two bicycle travel safety warning systems 20 of the two bicycles 30 and 34 can be implemented in a linked manner.
