Anti-drunk driving device and method thereof

The present invention relates to an anti-drunk driving device and a method thereof, and more particularly to identifying a driving pupil change by a pupil image sensing module and/or sensing the driving body swing by the sensing offset module The offset and the device and method for controlling the automatic restriction driving of the automobile, limiting the driving of the red light control, and automatically correcting the vehicle offset.

At present, in the society, passers-by are generally on the road, and they tend to pay attention to their own driving safety. Generally, drinking driving often claims to be not drunk, and then driving on the road by themselves, but often causes irreparable damage, that is, drunk driving in recent years. As a result, cases of car accidents are on the rise, so further prevention and avoidance are needed.

In addition, the current case concerning the prevention of drunk driving, such as the Republic of China Invention Patent Notice No. I377140 "Method of Anti-drunk Driving", uses a touch-sensitive LCD or LED panel to display randomly arranged numbers or characters, and requires users (The testee) enters the password set by the touch panel on the display panel. After calculating the time required to input the correct password, the time can be converted into the clarity of the mind and compared with the time required for the correct input. The input is completed within the average of the time of the correct input of the password, and exceeds the standard deviation time of the average of the use time, that is, the vehicle is not activated to prevent the drunken or unconscious person from driving the vehicle, endangering himself and The safety of others.

In addition, avoiding driving and drinking, and insisting on driving on the road, the case is like the Republic of China Invention Patent Notice No. 582349 "Warning device that avoids driver's departure from the lane", which is mainly used in two vehicles. a vehicle warning device is disposed on each side; the vehicle warning device is provided with a voltage power supply, a light quantity sensor, a signal amplifier, a voltage comparison amplifier and a warning display; wherein the light quantity is The sensor senses the amount of light reflected by the road dividing line, and the amount of light reflected by the road dividing line is greater than the portion of the road without the dividing line, so that the light quantity sensor generates different current values by the difference of the amount of reflected light, and the current value passes the signal. The modulation of the amplifier changes the current value into a suitable voltage difference, and then compares the voltage with the voltage comparison amplifier to obtain a voltage output signal, and then sends the voltage output signal to the warning display, and the warning display is used to remind the driving The person is used to remind the driver that the vehicle he is driving has deviated from the driving lane, and the driver can improve the driving safety of the driver and increase the probability of accidents.

In addition, as disclosed in the Republic of China Invention Patent Publication No. 201330827 "Attention Detection Device and Method Based on Driving Reflection Action", it is used to monitor the reflection action at the moment of driving, and to determine the degree of concentration of driving, mainly by asking questions and driving The method of answering and determining the device includes an image capturing unit for obtaining driving images, the processing module performs image digital processing on the image, the safety detecting unit provides a safety detecting instruction, and the safety determining unit performs numerical comparison according to the characteristics of the image. It is determined that when the image does not meet the requirements of the safety detection instruction, a warning message is issued to prompt the driving.

However, the previous case still has the following shortcomings:

1. The method of "anti-drunk driving" requires the user (subject) to enter the password set on the touch panel of the display panel. If the user who is drinking (the person under test) enters the correct password clearly, You can drive on the road, but the user (subject) may be unconscious during driving, so it is quite dangerous.

2. It is known that the warning device that avoids the driver's deviation from the lane can warn the driver that the vehicle body has deviated from the driving lane. However, if the driver is still unconscious due to alcohol, it is impossible to correct the vehicle that has deviated from the driving lane. Body, it will still cause problems in driving safety.

3. The conventional "attention detection device and method based on driving reflection" is mainly used to monitor the reflection action at the moment of driving, but the driving may be able to concentrate instantly in the reaction, and if the image does not meet the safety detection When the instruction is required, a warning message is issued to remind the driver, but the above is still unable to ensure the safety of driving.
