The subject matter herein generally relates to road traffic safety.
A warning triangle raised at a distance from a broken-down car can warn other vehicles to slow down, change lanes. A current mobile warning triangle cannot adjust its own speed according to the slope of a road.
Implementations of the present technology will now be described, by way of example only, with reference to the attached figures.
It will be appreciated that for simplicity and clarity of illustration, where appropriate, reference numerals have been repeated among the different figures to indicate corresponding or analogous elements. In addition, numerous specific details are set forth in order to provide a thorough understanding of the embodiments described herein. However, it will be understood by those of ordinary skill in the art that the embodiments described herein can be practiced without these specific details. In other instances, methods, procedures, and components have not been described in detail so as not to obscure the related relevant feature being described. Also, the description is not to be considered as limiting the scope of the embodiments described herein. The drawings are not necessarily to scale and the proportions of certain parts may be exaggerated to better illustrate details and features of the present disclosure. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean “at least one”.
Several definitions that apply throughout this disclosure will now be presented.
The term “coupled” is defined as connected, whether directly or indirectly through intervening components, and is not necessarily limited to physical connections. The connection can be such that the objects are permanently connected or releasably connected. The term “comprising,” when utilized, means “including, but not necessarily limited to”; it specifically indicates open-ended inclusion or membership in the so-described combination, group, series, and the like.
The mobile warning triangle 200 comprises a warning triangle 10, a base 20, at least two wheels, and a control system 100 (shown in
For example, a car may break down on a expressway or in a tunnels, the mobile warning triangle 200 is raised at a first distance from the car to warn other vehicles to slow down or change lanes. The first distance can be 100 meters or 150 meters for example.
In one exemplary embodiment, the mobile warning triangle 200 can implement a route planning operation through connections to the Internet. For example, the mobile warning triangle 200 can connect to the Internet to use the global positioning system (GPS) technology to implement the route planning operation. The mobile warning triangle 200 also can connect to the Internet to receive the route planning operation, for example, from a cloud server.
Referring to
In one exemplary embodiment, the driver 1 can be a motor. The driving controller 2 can be a motor controller. The detector 3 can comprise an accelerometer to obtain road information. The processor 4 can be a micro-programmed control unit (MCU).
In one exemplary embodiment, the processor 4 can further determine whether the road 300 is an uphill road, a downhill road, or a leveled road according to the road information.
When the processor 4 determines that the road 300 is an uphill road, the processor 4 outputs a first control signal to the driving controller 2 to increase the rotation speed of the driver 1 to control the mobile warning triangle 200 to maintain the predetermined speed. The control system 100 can prevent the mobile warning triangle 200 from stalling.
When the processor 4 determines that the road 300 is a downhill road, the processor 4 outputs a second control signal to the driving controller 2 to decrease the rotation speed of the driver 1 to control the mobile warning triangle 200 to maintain the predetermined speed. The control system 100 can prevent the mobile warning triangle 200 from losing direction because of speeding down uncertain ground.
When the processor 4 determines that the road 300 is a leveled road, the processor 4 outputs a third control signal to the driving controller 2 to maintain a constant rotation speed of the driver 1 to control the mobile warning triangle 200 to maintain the predetermined speed.
In step 300, the driving controller 2 controls the driver 1 to drive the mobile warning triangle 200 to move on the road 300 at a predetermined speed.
In step 302, the detector 3 obtains road information of the road 300.
In step 304, the processor 4 outputs a corresponding control signal to the driving controller 2 according to the road information to control the mobile warning triangle 200 to maintain the predetermined speed while moving.
In one exemplary embodiment, the processor 4 further determines the road 300 to be an uphill road, a downhill road, or a leveled road according to the road information.
When the processor 4 determines that the road 300 is an uphill road, the processor 4 outputs a first control signal to the driving controller 2 to increase the rotation speed of the driver 1 to control the mobile warning triangle 200 to maintain the predetermined speed.
When the processor 4 determines that the road 300 is a downhill road, the processor 4 outputs a second control signal to the driving controller 2 to decrease the rotation speed of the driver 1 to control the mobile warning triangle 200 to maintain the predetermined speed.
When the processor 4 determines that the road 300 is a leveled road, the processor 4 outputs a third control signal to the driving controller 2 to maintain a constant rotation speed of the driver 1 to control the mobile warning triangle 200 to maintain the predetermined speed.
The exemplary embodiments shown and described above are only examples. Many such details are neither shown nor described. Even though numerous characteristics and advantages of the present technology have been set forth in the foregoing description, together with details of the structure and function of the present disclosure, the disclosure is illustrative only, and changes may be made in the detail, including in matters of shape, size, and arrangement of the parts within the principles of the present disclosure, up to and including the full extent established by the broad general meaning of the terms used in the claims. It will therefore be appreciated that the exemplary embodiments described above may be modified within the scope of the claims.
