Abstract

A human-transporting vehicle has a chamber, a gas collector, a detection circuit and a determination circuit for improving driving safety. The gas collector collects a gas sampling and the determination circuit determines whether a concentration of a certain composition in the gas sampling exceeds a predetermined value. If the determination result is positive, the determination circuit disables the vehicle so that the vehicle cannot start. An audio device and a display are utilized for providing the driver with information to know whether it is safe to drive the vehicle.

Claims

1. A human-transporting vehicle for improving driving safety, comprising:

a chamber for containing a driver to sit inside to drive the vehicle;

a gas collector for extracting a gas sampling from the chamber;

a detection circuit for detecting a concentration of at least one certain composition in the gas sampling; and

a determination circuit coupled to the detection circuit for preventing the vehicle from being started if the concentration of the at least one preventing certain composition in the gas sampling exceeds a predetermined value.

2. The human-transporting vehicle of claim 1, further comprising a starter device coupled to the determination circuit for starting the vehicle.

3. The human-transporting vehicle of claim 2, wherein the gas collector, the detection circuit and the determination circuit are triggered for extracting the gas sampling and determining the concentration of the certain composition in the gas sampling when the driver activates the starter device.

4. The human-transporting vehicle of claim 1, further comprising a safety belt device, wherein the gas collector, the detection circuit and the determination circuit are triggered for extracting the gas sampling and determining the concentration of the certain composition in the gas sampling when the driver uses the safety belt device.

5. The human-transporting vehicle of claim 1, wherein the chamber has a seat sensor and the gas collector, the detection circuit and the determination circuit are triggered for extracting the gas sampling and determining the concentration of the certain composition in the gas sampling when the seat sensor detects the driver sitting in the chamber.

6. The human-transporting vehicle of claim 1, wherein the gas collector is placed in the chamber for collecting gas inside the chamber as the sampling gas.

7. The human-transporting vehicle of claim 1, wherein the gas collector has a blow entrance for the driver to blow so as to obtain the gas sampling.

8. The human-transporting vehicle of claim 7, further comprising an audio device installed in the chamber to inform the driver to blow the blow entrance.

9. The human-transporting vehicle of claim 8, wherein the audio device reminds the driver about whether it is suitable for driving.

10. The human-transporting vehicle of claim 8, further comprising a display coupled to the determination circuit for showing a determination result of the determination circuit.

11. The human-transporting vehicle of claim 1, wherein the chamber has at least one window and the window is closed until the determination circuit finishes the determination.

12. The human-transporting vehicle of claim 1, wherein the determination circuit checks whether the chamber is airtight to ensure the correctness of the determination of the determination circuit.

13. The human-transporting vehicle of claim 1, wherein the chamber contains a steering wheel and the gas collector is installed on the steering wheel.

14. The human-transporting vehicle of claim 1, wherein the certain composition comprises alcohol.

15. The human-transporting vehicle of claim 1, wherein the certain composition comprises human-harming gas.

16. The human-carrying vehicle of claim 1, wherein the vehicle is a car.

17. An auxiliary device for installed in a vehicle for improving driving safety, the vehicle having a chamber, the device comprising:

a gas collector for extracting a gas sampling of the chamber;

a detection circuit for detecting a concentration of at least one certain composition in the gas sampling; and

a determination circuit coupled to the detection circuit for stopping the vehicle to start if the concentration of the certain composition exceeds a predetermined value.

18. The auxiliary device of claim 17, wherein the vehicle further comprises a starter device coupled to the determination circuit for starting the vehicle and the determination circuit are triggered for extracting the gas sampling and determining the concentration of the certain composition in the gas sampling when the driver activates the starter device.

19. The auxiliary device of claim 17, wherein gas collector is installed in the chamber for sucking gas in the chamber as the sampling gas.

20. The auxiliary device of claim 17, wherein the gas collector comprises a blow entrance for the driver to blow to obtain the gas sampling.
