Drunk Driving Prevention System and Method

Abstract

A drunk driving prevention system for a vehicle includes an eye symptom detector adapted for supporting in the vehicle at a position to detect eye symptoms of a driver, a control module operatively linked to the eye symptom detector for determining and analyzing whether the eye symptoms of the driver match with alcohol influenced eye symptoms, and a signal module operatively linked control module for generating a drunk driving signal in response to the alcohol influenced eye symptoms that suspect an alcohol concentration of the driver is above a predetermined threshold.

What is claimed is: 
     
         1 . A drunk driving prevention system for a vehicle, comprising:
 an eye symptom detector supporting at a position to detect eye symptoms of a driver of the vehicle;   a control module, operatively linked to said eye symptom detector, determining and analyzing whether said eye symptoms of said driver match with alcohol influenced eye symptoms; and   a signal module, operatively linked control module, generating a drunk driving signal in response to said eye symptoms of said driver that suspects an alcohol concentration of said driver is above a predetermined threshold.   
     
     
         2 . The drunk driving prevention system, as recited in  claim 1 , wherein said control module comprises a memory unit storing data of normal eye symptoms, and a comparison unit comparing detected eye symptoms by said eye symptom detector to said normal eye symptoms to determine whether said eye symptoms of said driver are alcohol influenced eye symptoms. 
     
     
         3 . The drunk driving prevention system, as recited in  claim 1 , wherein said eye symptom detector is activated in response to a start of said vehicle and is deactivated in response to said vehicle being turned off. 
     
     
         4 . The drunk driving prevention system, as recited in  claim 1 , wherein said control module comprises a sobriety test guidance operatively linked to said eye symptom detector for guiding said driver to perform a sobriety test when said eye symptom detector detects eye movements of said driver. 
     
     
         5 . The drunk driving prevention system, as recited in  claim 4 , wherein said control module comprises a sobriety test guidance operatively linked to said eye symptom detector for guiding said driver to perform a sobriety test when said eye symptom detector detects eye movements of said driver. 
     
     
         6 . The drunk driving prevention system, as recited in  claim 1 , wherein said eye symptom detector is selected from a group consisting of an eyeball movement sensor for detecting eyeball movements of said driver, an pupil sensor for detecting sizes of pupils of said driver, and an ocular conjunctival blood vessel capturer for detecting an ocular conjunctival blood vessel of said driver. 
     
     
         7 . The drunk driving prevention system, as recited in  claim 1 , wherein said signal module comprises an ignition deactivator for operatively linking to an igniter of said vehicle, wherein when said alcohol influenced eye symptoms are determined, said ignition deactivator is activated for preventing an ignition of said vehicle. 
     
     
         8 . The drunk driving prevention system, as recited in  claim 1 , further comprises a facial recognition module linked to said control module for capturing an image of the driver's face when said eye symptom detector detects said eye symptoms of said driver. 
     
     
         9 . The drunk driving prevention system, as recited in  claim 1 , wherein said signal module further comprises a communication unit for sending a suspected drunk driving signal to a police or a drunk driving control organization when said alcohol influenced eye symptoms are kept detecting for a predetermined control time period. 
     
     
         10 . A method for preventing drunk driving a vehicle, comprising the steps of:
 (a) detecting eye symptoms of a driver;   (b) analyzing whether said eye symptoms of said driver are alcohol influenced eye symptoms by a control module;   (c) enabling said driver to drive said vehicle if said eye movements of said driver detected are normal eye symptoms; and   (d) generating a drunk driving signal by a signal generator if said eye symptoms of said driver are detected as alcohol influenced eye symptoms that suspects an alcohol concentration of said driver is above a predetermined threshold.   
     
     
         11 . The method, as recited in  claim 10 , wherein an eye symptom detector is activated in response to a start of said vehicle to detect the eye symptoms of the driver in the step (a) and is deactivated in response to said vehicle being turned off 
     
     
         12 . The method, as recited in  claim 10 , wherein the step (a) further comprises a step of executing a sobriety test for said driver by said control module when said eye symptom detector detects eye movements of said driver. 
     
     
         13 . The method, as recited in  claim 11 , wherein the step (a) further comprises a step of executing a sobriety test for said driver by said control module when said eye symptom detector detects eye movements of said driver. 
     
     
         14 . The method, as recited in  claim 10 , wherein the step (a) further comprises at least one of the steps of detecting eyeball movements of said driver, detecting sizes of pupils of said driver, and detecting the ocular conjunctival blood vessel of said driver. 
     
     
         15 . The method, as recited in  claim 13 , wherein the step (a) further comprises at least one of the steps of detecting eyeball movements of said driver, detecting sizes of pupils of said driver, and detecting the ocular conjunctival blood vessel of said driver. 
     
     
         16 . The method, as recited in  claim 10 , wherein the step (c) further comprises a step of deceiving an igniter of said vehicle when said alcohol influenced eye symptoms are determined for preventing an ignition of said vehicle. 
     
     
         17 . The method, as recited in  claim 15 , wherein the step (c) further comprises a step of deceiving an igniter of said vehicle when said alcohol influenced eye symptoms are determined for preventing an ignition of said vehicle. 
     
     
         18 . The method, as recited in  claim 10 , further comprising a step of capturing an image of the driver's face by a facial recognition module when said eye symptom detector detects said eye symptoms of said driver. 
     
     
         19 . The method, as recited in  claim 17 , further comprising a step of capturing an image of the driver's face by a facial recognition module when said eye symptom detector detects said eye symptoms of said driver. 
     
     
         20 . The method, as recited in  claim 10 , further comprising a step of sending a suspected drunk driving signal to a police or a drunk driving control organization when said alcohol influenced eye symptoms are kept detecting for a predetermined control time period. 
     
     
         21 . The method, as recited in  claim 19 , further comprising a step of sending a suspected drunk driving signal to a police or a drunk driving control organization when said alcohol influenced eye symptoms are kept detecting for a predetermined control time period.
