Abstract

A warning system applied to a vehicle includes a control module, a detecting module, a warning module, and a pressure sensor module. The pressure sensor module is assembled to a seat, and configured to measure a pressure value of the seat and transmit the pressure value to the control module. The detecting module is configured to obtain information of the environment around the vehicle and transmit the information to the control module. The control module is configured to determine whether there is at least one person sitting on the seat based on the pressure value on the seat, and to determine whether there is a passing vehicle based on the information of the environment surrounding the vehicle, and warn the passing vehicle when there is someone sitting on the seat and there is a passing vehicle.

Claims

1. A warning system applied for a vehicle, the vehicle comprising a seat, the system comprising:

a control module,

a detecting module assembled to the vehicle and electrically coupled to the control module;

a warning module assembled to the vehicle and electrically coupled to the control module; and

a pressure sensor module assembled to a seat of the vehicle and electrically coupled to the control module;

wherein the pressure sensor module is configured to measure a pressure value of the seat and transmit the pressure value to the control module, the control module is configured to calculate a pressure difference between the pressure value and a predetermined value to determine whether there is at least one person sitting on the seat; and

wherein the detecting module is configured to obtain information of the environment around the vehicle and transmit the information to the control module, and the control module is further configured to determine whether there is a passing vehicle based on the information and control the warning module to warn the passing vehicle when there is someone sitting on the seat and there is a passing vehicle.

2. The warning system of claim 1, wherein the detecting module comprises an ultrasonic detecting unit, the ultrasonic detecting unit is configured to transmit and receive ultrasonic signals, and is capable of measuring a distance module between the vehicle and another vehicle based on the ultrasonic signals and transmitting the distance value to the control module, the control module is configured to analyze the distance value to determine whether there is a passing vehicle.

3. The warning system of claim 1, wherein the detecting module comprises a camera unit, the camera unit is configured to take images around the vehicle and transmit the images to the control module, the control module is configured to analyze the images to determine whether there a passing vehicle.

4. The warning system of claim 1, wherein the warning module comprises a lamp warning unit, the control module control the lamp warning unit to warn the passing vehicle.

5. The warning system of claim 1, wherein the warning module comprises a voice warning unit, the control module control the voice warning unit to warn the passing vehicle.

6. The warning system of claim 1, wherein the warning system further comprises a power source module, the control module, the pressure sensor module, the detecting module, and the warning module are electrically coupled to the power source module respectively.

7. The warning system of claim 1, wherein the detecting module is configured to obtain the information within an area around the vehicle less then predetermined distance.

8. The warning system of claim 1, wherein the detecting module is assemble to a side of the vehicle.

9. The warning system of claim 1, wherein the warning module is assembled to a top surface of the vehicle.

10. A warning method applied to a vehicle, the vehicle comprising a seat, the method comprising:

measuring a pressure value of the seat;

calculating a pressure difference between the pressure value and a predetermined value to determine whether there is at least one person sitting on the seat;

obtaining information of the environment around the vehicle;

determining whether there is a passing vehicle based on the information; and

warning the passing vehicle when there is at least one person sitting on the seat and there is a passing vehicle.

11. The warning method of claim 10, wherein the method further comprises:

transmitting and receiving ultrasonic signals to obtaining the information of the environment around the vehicle.

12. The warning method of claim 10, wherein the method further comprises:

taking images around the vehicle to obtain the information of the environment around the vehicle.

13. The warning method of claim 10, wherein the vehicle comprises a warning module comprising a lamp warning unit, the method further comprises:

controlling the lamp warning unit to warn the passing vehicle when there is at least one person sitting on the seat and there is a passing vehicle.

14. The warning method of claim 10, wherein the vehicle comprises a warning module comprising a voice warning unit, the method further comprises:

controlling the voice warning unit to warn the passing vehicle when there is at least one person sitting on the seat and there is a passing vehicle.
