  The alcohol detection sensor 10 is for detecting the drinking state of the driver, and functions as a drinking detection unit described in the claims. As the alcohol detection sensor 10, one using a semiconductor, one using a fuel cell, or one using infrared rays can be applied.

  The alcohol detection sensor using a semiconductor utilizes the characteristic that the amount of electrons originally flowing in the semiconductor is absorbed and changed by the alcohol in the air in the passenger compartment. In the alcohol detection sensor of this principle, the electrical resistance in the sensor changes as the amount of electrons in the semiconductor changes, so the presence or absence of alcohol and the alcohol concentration in the breath of the driver are estimated from the strength of the electrical resistance. can do.

  An alcohol detection sensor using a fuel cell utilizes the characteristics of a fuel cell that can generate electrons from alcohol in the air in the passenger compartment. In the alcohol detection sensor based on this principle, the amount of electrons produced by alcohol becomes the strength of the flow of electricity, so the presence or absence of alcohol and the alcohol concentration in the breath of the driver are estimated from the strength of the current. be able to.

  The alcohol detection sensor using infrared rays utilizes the characteristic that infrared rays are absorbed by alcohol in the air in the passenger compartment. In the alcohol detection sensor based on this principle, infrared light absorbed by alcohol is converted into an electrical signal by a photodetector, and the electrical signal is analyzed by a microprocessor to estimate the presence of alcohol and the alcohol concentration in the driver's breath. can do.

  In addition, as the alcohol detection sensor 10 in a business vehicle, it is good also as what measures the alcohol density | concentration in a driver | operator's expiration or blood directly.

  The weather detection sensor 12 is for detecting stormy weather such as rainfall, snowfall or strong wind outside the vehicle. As the weather detection sensor 12, a radar rain gauge, an anemometer, and an anemometer can be applied. In particular, as the weather detection sensor 12, a Doppler radar type rain gauge can be applied. The Doppler radar rain gauge is capable of observing the moving speed of raindrops moving away from or approaching the radar using the Doppler effect of 1 to 50 GHz radar waves. It is preferable because a difference between rain and snow can be detected.

  The raindrop intensity measurement sensor 14 is installed on the outer surface of each of the sunroof 20 and the windows 24a to 24n of the vehicle, and detects the amount of rainfall and the amount of snowfall at each part. The weather detection sensor 12 and the raindrop strength measurement sensor 14 function as weather detection means described in the claims.

  The actuation determination unit 16 is for giving a command signal to the sunroof actuator 18 and the window actuators 22a to 22n based on information from the alcohol detection sensor 10, the weather detection sensor 12, and the raindrop strength measurement sensor 14, and is physically Is configured using microcomputer hardware and software such as an ECU (Electric Control Unit).

  The sunroof actuator 18 and the window actuators 22a to 22n are for opening and closing the sunroof 20 and the windows 24a to 24n, respectively, based on a command signal from the actuation determination unit 16, and function as opening and closing means according to the claims. To do.

  Next, the operation of the drunk driving suppression system of the present embodiment will be described with reference to FIG. The drinking prevention system 1 of this embodiment starts operation from a state where the driver has started the engine. FIG. 2 is a flowchart showing the operation of the drunk driving suppression system according to the first embodiment. As shown in FIG. 2, the weather detection sensor 12 and the raindrop intensity measurement sensor 14 detect whether or not the weather outside the vehicle is during stormy weather such as rain, snowfall, or strong wind (S11). In the case of stormy weather, the alcohol detection sensor 10 detects the drunk state of the driver (S12).

  When the alcohol detection sensor 10 detects that the alcohol concentration in the expiration of the driver is 15 mg / L or more, which is the prescribed value of the alcoholic state (S13), the sunroof actuator 18 opens the sunroof 20 (S14). If the alcohol detection sensor 10 detects the alcohol concentration in the driver's breath as 25 mg / L, which is the prescribed value for the drunk state (S15), the window actuators 22a to 22n open all the windows 24a to 24n ( S16). In this case, the opening degree of each of the sunroof 20 and the windows 24a to 24n may be increased according to the amount of alcohol consumed by the driver.

  According to the present embodiment, the sunroof actuator 18 and the window actuators 22 a to 22 n detect the driver's drinking state by the alcohol detection sensor 10, and the rain and snowfall outside the vehicle by the weather detection sensor 12 and the raindrop strength measurement sensor 14. When at least one of these is detected, one of the sunroof 20 and the windows 24a to 24n of the vehicle is opened. For this reason, it is possible to give a sense of discomfort due to rainfall or snowfall to drinkers whose judgment, reflex ability, etc. have decreased, and to raise concerns about the effect on the interior of the passenger compartment. Therefore, it can be expected that the driver who is concerned about the influence on the interior is less willing to continue the driving operation, and that the driving operation is stopped by voluntarily stopping the vehicle. Moreover, according to this structure, since it does not cause the change of the motor performance of a vehicle, the change of a driving characteristic, and a visual field defect, safety | security is also ensured.

  Further, according to the present embodiment, the sunroof actuator 18 and the window actuators 22a to 22n open the sunroof 20 and the windows 24a to 24n as the alcohol intake amount in the driver's drinking state detected by the alcohol detection sensor 10 increases. In order to increase the degree, the more drunk the driver is, the more he can give the driver discomfort due to rain or snow and the concern about the influence on the interior of the vehicle interior, and drunk driving can be suppressed. Furthermore, according to this configuration, there is an advantage that it is possible to prevent the interior of the vehicle interior from being adversely affected by rain and snow more than necessary.

  Hereinafter, a second embodiment of the present invention will be described. FIG. 3 is a flowchart showing the operation of the drunk driving suppression system according to the second embodiment. The present embodiment is different from the first embodiment in that a window with higher raindrop strength is preferentially opened. As shown in FIG. 3, in this embodiment, after judging whether it is a stormy weather (S21) and alcohol detection (S22, S23) as in the first embodiment, the raindrop intensity measuring sensor 14 The amount of rainfall and the amount of snowfall in each of the sunroof 20 and the windows 24a to 24n are detected (S24).

  The actuation determination unit 16 determines the priority of opening the raindrop strength from the raindrop strength measurement sensor 14 and the predetermined weight coefficients of the sunroof 20 and the windows 24a to 24n of the vehicle. The weighting coefficient of the sunroof 20 and the windows 24a to 24n can be set so that, for example, the sunroof 20 is the largest and decreases from the front window to the rear window. Thus, the priority for opening the sunroof 20 and the windows 24a to 24n can be determined by setting (raindrop intensity of each part × weighting coefficient of each part = priority). The sunroof actuator 18 and the window actuators 22a to 22n open the sunroof 20 and the windows 24a to 24n according to the priority determined in this way (S25).

  In this case, by measuring the direction of rainfall, snowfall, and wind direction with the weather detection sensor 12 and the raindrop strength measurement sensor 14, and by making the opening of the windward window larger than the opening of the windward window, It is possible to secure a passage and to promote the intake and passage of wind and rain.

  According to the present embodiment, the sunroof actuator 18 and the window actuators 22a to 22n open from the roof and the vehicle window having a large amount of rainfall, snowfall and airflow in any of the sunroof 20 and the windows 24a to 24n of the vehicle, and therefore, more efficiently. It is possible to give the driver discomfort due to rain or snow and concerns about the influence on the interior of the passenger compartment. Further, according to the present embodiment, the window actuators 22a to 22n secure the wind passage by increasing the opening degree of the windward window from the opening degree of the leeward window, and promote the suction and passage of wind and rain. can do.

  Although the embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and various modifications can be made.
