Abstract

A control system for maintaining a traffic warning triangle at a constant speed when deployed, notwithstanding rises and falls in the road surface, includes a driver, a driving controller, a detector, and a processor. The driving controller controls the driver to drive the mobile warning triangle to move on a road at a predetermined speed. The detector obtains information as to the road. The processor outputs control signals to the driving controller to control the mobile warning triangle to move at the constant predetermined speed when moving. A control method of the mobile warning triangle is also provided.

First claim

What is claimed is:

1. A control method of a mobile warning triangle comprising:
controlling a driver to drive the mobile warning triangle to move on a road at a constant speed;
obtaining road information of the road; and
regulating a rotation speed of the driver according to the road information to control the mobile warning triangle to maintain the constant speed while moving;
wherein the step of regulating a rotation speed of the driver according to the road information to control the mobile warning triangle to maintain the constant speed to move comprises:
increasing the rotation speed of the driver directly to control the mobile warning triangle to maintain the constant speed to move in response to the road being an uphill road; and
decreasing the rotation speed of the driver directly to control the mobile warning triangle to maintain the constant speed to move in response to the road being a downhill road.

2. The control method of claim, wherein the step of regulating a rotation speed of the driver according to the road information of the road to control the mobile warning triangle to maintain the constant speed to move further comprises:
maintaining a constant rotation speed of the driver to control the mobile warning triangle to maintain the constant speed to move in response to the road being a leveled road.

3. A control system of a mobile warning triangle, the control system comprising:
a driver;
a driving controller coupled to the driver, the driving controller controlling the driver to drive the mobile warning triangle to move on a road at a constant speed;
a detector obtaining road information of the road; and
a processor coupled to the driving controller and the detector, the processor outputting a corresponding control signal to the driving controller according to the road information to control the mobile warning triangle to maintain the constant speed while moving
wherein the processor further determines whether the road is an uphill road, a downhill road, or a leveled road according to the road information; when the processor determines the road to be the uphill road, the processor outputs a first control signal to the driving controller to directly increase the rotation speed of the driver to control the mobile warning triangle to maintain the constant speed while moving; and when the processor determines the road to be the downhill road, the processor outputs a second control signal to the driving controller to directly decrease the rotation speed of the driver to control the mobile warning triangle to maintain the constant speed while moving.

4. The control system of claim 3 , wherein the processor further implements a route planning operation through connections to the Internet.

5. The control system of claim 3 , wherein when the processor determines the road to be the leveled road, the processor outputs a third control signal to the driving controller to maintain a constant rotation speed of the driver to control the mobile warning triangle to maintain the constant speed while moving.

6. A mobile warning triangle comprising:
a warning triangle;
a base;
at least two wheels installing on two sides of the base; and
a control system comprising:
a driver;
a driving controller coupled to the driver, the driving controller controlling the driver to drive the mobile warning triangle to move on a road at a constant speed;
a detector obtaining road information of the road; and
a processor coupled to the driving controller and the detector, the processor outputting a corresponding control signal to the driving controller according to the road information to control the mobile warning triangle to maintain the constant speed while moving
wherein the processor further determines whether the road is an uphill road, a downhill road, or a leveled road according to the road information of the road; when the processor determines the road to be the uphill road, the processor outputs a first control signal to the driving controller to directly increase the rotation speed of the driver to control the mobile warning triangle to maintain the constant speed while moving; and when the processor determines the road to be the downhill road, the processor outputs a second control signal to the driving controller to directly decrease the rotation speed of the driver to control the mobile warning triangle to maintain the constant speed while moving.

7. The mobile warning triangle of claim 6 , wherein the processor further implements a route planning operation through connections to the Internet.

8. The mobile warning triangle of claim 6 , wherein when the processor determines the road to be the leveled road, the processor outputs a third control signal to the driving controller to maintain a constant rotation speed of the driver to control the mobile warning triangle to maintain the constant speed while moving.
