Abstract

In a method for detecting and controlling of driving whilst under the influence of alcohol, breath alcohol concentrations of a user are received from an alcohol sensor at predetermined time periods. The breath alcohol concentrations are analyzed to construct a regression curve, and a target time when the user will have become sober can be predicted according to the regression curve. When a dangerous work is done before the target time, an audible warning can be outputted through an output device.

First claim

What is claimed is:

1 . A method for detecting and controlling driving under the influence, the method executable by at least one processor of an electronic device and comprising:
receiving breath alcohol concentrations of a user via an alcohol sensor at predetermined time periods; establishing a regression curve according to the breath alcohol concentrations; predicting a target time that the user is regarded as sober according to the regression curve; and outputting a warning via an output device when driving occurs prior to the target time.

2 . The method according to claim 1 , further comprising:
outputting the target time through the output device.

3 . The method according to claim 1 , wherein the target time is a time that the breath alcohol concentrations of the user has decreased to an amount which is equal to or less than a permitted value.

4 . The method according to claim 1 , further comprising:
sensing a movement speed of the user before the target time; and outputting a warning when the movement speed is greater than a predetermined threshold.

5 . An electronic device, comprising:
an output device; at least one processor; and a storage storing one or more programs which, when executed by the at least one processor, causes the at least one processor to: receive breath alcohol concentrations of a user via an alcohol sensor at predetermined time periods; establish a regression curve according to the breath alcohol concentrations; predict a target time that the user is regarded as sober according to the regression curve; and output a warning via an output device when driving occurs prior to the target time.

6 . The electronic device according to claim 5 , wherein the at least one processor further:
outputs the target time through the output device.

7 . The electronic device according to claim 5 , wherein the target time is a time that the breath alcohol concentrations of the user has decreased to an amount which is equal to or less than a permitted value.

8 . The electronic device according to claim 7 , wherein the electronic device further comprises a speed sensor which senses movements of the user; and when sensing that a movement speed of the user is greater than a predetermined threshold before the target time, it is determined that the user is doing a dangerous work.

9 . The electronic device according to claim 5 , wherein the alcohol sensor is located inside of the electronic device.

10 . The electronic device according to claim 9 , wherein the electronic device further comprises holes which are located above the alcohol sensor.

11 . A non-transitory storage medium having stored thereon instructions that, when executed by at least one processor of an electronic device, causes the at least one processor to perform a method for detecting and controlling of driving under the influence, the method comprising:
receiving breath alcohol concentrations of a user via an alcohol sensor at predetermined time periods; establishing a regression curve according to the breath alcohol concentrations; predicting a target time that the user is regarded as sober according to the regression curve; and outputting a warning via an output device when driving occurs prior to the target time.

12 . The non-transitory storage medium according to claim 11 , wherein the method further comprises:
outputting the target time through the output device.

13 . The non-transitory storage medium according to claim 11 , wherein the target time is a time that the breath alcohol concentrations of the user has decreased to an amount which is equal to or less than a permitted value.

14 . The non-transitory storage medium according to claim 11 , wherein the method further comprises:
sensing a movement speed of the user before the target time; and outputting a warning when the movement speed is greater than a predetermined threshold.
