Description

The present invention relates to a drunk driving detection device that detects a driver's drinking state.

Drunk driving misleads normal judgment when driving. In order to eradicate or reduce drunk driving, devices have been developed that detect alcohol components in the exhaled breath of drunk drivers and issue warnings.

For example, the "system and method for preventing a drunk person from driving a car" described in Patent Document 1 is a percutaneous alcohol detection device that always uses either the driver's left hand or the right hand when the driver touches the handle. It is prepared to come into contact with and measures the presence of ethyl alcohol in human skin so that no one can interfere with the system by wearing special gloves to avoid the detection of alcohol. In addition, a constant temperature measurement is made.

Further, in Patent Document 2, "a device for preventing driving by an unqualified person", a blood pressure / heart rate sensor, an alcohol detection sensor, and an eyeball measurement sensor are used to determine whether or not the driver of the own vehicle is in an unsuitable state for driving. Whether the driver has a serious illness such as heart disease by detecting the driver's blood pressure and heart rate with the blood pressure / heart rate sensor, or whether the driver is in an unsuitable state due to medication etc. It is described that it is determined whether or not it is.

Japanese Patent Publication No. 2008-539127 Japanese Unexamined Patent Publication No. 2010-6230

However, in Patent Document 1, "Systems and Methods for Preventing Drunk Humans from Driving a Car", whether or not the driver is holding the steering wheel is determined based on the body temperature, and the alcohol component is detected from the driver. It does not improve the accuracy.
Further, also in Patent Document 2, "a device for preventing driving by a driving invincible company", the driver's blood pressure and heart rate are detected by the blood pressure / heart rate sensor, and the driver is a seriously ill person such as a heart disease. This is for determining whether or not the patient is in an unsuitable state for driving due to medication or the like, and does not improve the accuracy of detecting an alcohol component from the driver.

When detecting alcohol components from the atmosphere of the driver's seat where the driver sits, for example, if a passenger car is located in the passenger seat, or if the bus is located near the driver's seat, another person who has consumed alcohol is located. , Alcohol components may be erroneously detected in the air, and the driver may mistakenly think that he / she is drinking.

Therefore, the present invention provides a drunk driving detection device capable of improving the detection accuracy of whether or not the driver is in a drunk driving state when the alcohol component is detected from the atmosphere of the driver's seat where the driver sits. The purpose.

The drunk driving detection device of the present invention measures the alcohol concentration in the atmosphere of the driver's seat where the driver sits, the second sensor for measuring the body temperature of the driver, and the heart rate of the driver. When the alcohol concentration from the third sensor and the first sensor is higher than the first threshold value and the body temperature from the second sensor is higher than the second threshold value, or the alcohol concentration from the first sensor is higher than the first threshold value. A control device for determining a drinking state when the heart rate from the third sensor is high and higher than the third threshold value is provided , and the control unit has a resting heart rate corresponding to age and gender. It is provided with a storage unit in which statistical data is stored, and is characterized in that the heart rate from the statistical data of the resting heart rate based on the age and gender of the driver is determined as the third threshold value .

With the alcohol concentration measured by the first sensor, the body temperature measured by the second sensor, and the heart rate measured by the third sensor, the control device controls the alcohol concentration to be higher than the first threshold and the body temperature to be the second. If it is higher than the 2nd threshold, or if the alcohol concentration is higher than the 1st threshold and the heart rate is higher than the 3rd threshold, it is judged that the person is drinking, so that someone other than the driver is drinking and the alcohol component. Even if is detected, if the driver's body temperature is normal and the heart rate is determined to be at rest, it is possible to avoid misidentifying it as a drinking state.

The third sensor may be installed on the handle.
Further, the first sensor, the second sensor, the third sensor, and a wireless device for transmitting sensor information from the first to third sensors to a telecommunication line are mounted on the vehicle on which the driver is boarded. The control device may input information from the wireless device via the telecommunication line.
The vehicle on which the driver is boarding is equipped with a wireless device, and the vehicle is traveling over a wide range in order to determine whether the control device is in a drunken state based on the information from the wireless device via a telecommunication line. However, the drinking state of the driver can be grasped by the control device installed in the remote place.

The wireless device identifies a relay device, which is an in-vehicle device that transmits sensor information from the first sensor, the second sensor, and the third sensor by a wireless signal, a positioning unit that outputs position information, and a driver. A smartphone carried by a driver having a storage unit for storing identification information is provided , and the smartphone is a radio indicating sensor information by the first sensor, the second sensor, and the third sensor from the relay device. It is possible to receive the signal and transmit the position information and the identification information together with the sensor information to the control device via the telecommunications line by a wireless signal.
Since the smartphone has a positioning unit that outputs position information and a storage unit that stores identification information that identifies the driver, even if the driver who owns the smartphone changes vehicles, the first to the first is to the vehicle. If a third sensor and a relay device are installed, drunk driving can be monitored by a control device installed at a remote location.

It is desirable to install a notification unit that notifies the vehicle when it is determined to be in a drinking state based on the alcohol concentration measured by the first sensor so as to be recognizable from the outside.
Since the notification unit is installed in the vehicle so that it can be recognized from the outside, the driver can recognize that he / she is drinking from the outside of the vehicle, so that even if the driver is not aware of the drinking state, an outsider can recognize it. You can be careful.

The notification unit is provided with an LED that notifies by light emission, and since the LED is installed inside the glass surface of the vehicle with the LED facing outward, the notification unit can be easily installed and can be operated even from the outside of the vehicle. It is possible to easily visually recognize that the person is in a drinking state.

According to the drunk driving detection device of the present invention, when the alcohol component is detected from the atmosphere of the driver's seat where the driver sits, a person other than the driver is drinking alcohol, and even if the alcohol component is detected, the driver If the body temperature is normal and the heart rate is judged to be at rest, it is possible to avoid misidentifying it as a drunk driving state, so the accuracy of detecting whether the driver is drinking or not is improved. Can be made to.
