Problems solved by technology

However, if the volatilization amount of cedrol continues to increase, it will exceed the relaxed state, and it can be seen that there is a case of causing drowsiness instead.

no. 1 Embodiment approach

[0027] use Figure 1 to Figure 6 The vehicle fatigue relief device 100A in the first embodiment will be described. The vehicle fatigue relief device (hereinafter, fatigue relief device) 100A is a device for alleviating the driving fatigue of a vehicle occupant (driver) and suppressing drowsiness when drowsiness is induced by cedrol.

[0028] like figure 1 , figure 2 As shown, fatigue relief device 100A is mounted in instrument panel 50A of a vehicle equipped with an air conditioner, and includes supply unit 101 (bottle 110 , pump 120 ), detection unit 130 , control unit 140 and the like.

[0029] The supply unit 101 sprays and volatilizes cedrol into the vehicle interior, and includes a bottle body 110, a pump 120, and the like.

[0030] The bottle body 110 is a container body that accommodates cedrol alcohol therein. Cedrol becomes a mixed solvent described later. A mixed solvent of cedrol is accommodated up to an intermediate level in the bottle body 110 , and the uppe...

no. 2 Embodiment approach

[0066] Figure 8 A fatigue relief device 100B of the second embodiment is shown. In the second embodiment, an input unit 150 is added to the first embodiment described above.

[0067] The input unit 150 is, for example, an input switch provided on the instrument panel 50A near the driver's seat, and used for input by the driver. The input unit 150 is a switch capable of inputting a signal indicating that the driver feels anxious to the control unit 140 by performing an input operation when the driver feels anxious.

[0068] When receiving a signal from the input unit 150 , the control unit 140 operates the supply unit 101 to volatilize cedrol into the vehicle interior regardless of a detection signal such as a biometric signal from the detection unit 130 . That is, in the present embodiment, cedrol is also volatilized at the driver's request.

[0069] Furthermore, the control unit 140 learns and updates the criterion for determining the driver's anxiety level obtained from ...

no. 3 Embodiment approach

[0072] Figure 9 A fatigue relief device 100C of the third embodiment is shown. In the third embodiment, a heating unit 160 is added to the first embodiment described above.

[0073] The heating part 160 is operated and controlled by the control part 140, and heats the cedrol in the supply part 101, for example, using an electric heater or the like.

[0074] Thus, heating cedrol by the heating unit 160 can increase the volatilization rate of cedrol and increase the volatilization amount, which is effective when it is desired to increase the volatilization amount of cedrol into the vehicle interior.

Abstract

A stress relieving device for a vehicle comprises: a supply unit (101) for spraying and vaporizing cedrol inside a vehicle cabin; a detection unit (130) for detecting the degree of irritation and thedegree of sleepiness of an occupant inside the vehicle cabin; and a control unit (140) for causing the supply unit to operate and vaporize the cedrol inside the vehicle cabin on the basis of the degree of irritation detected by the detection unit, and controlling the supply unit to reduce the amount of the cedrol to be vaporized if a degree of sleepiness is detected by the detection unit. When thecedrol is vaporized in order to suppress the irritation of the occupant, a relaxation effect can be obtained, and when the passenger becomes too relaxed and feels sleepy, the amount of the cedrol tobe vaporized is reduced, making it possible to control sleepiness.

Description

[0001] Cross-reference of related applications [0002] This application is based on the JP Patent application 2015-222318 for which it applied on November 12, 2015, The content of this indication is taken in in this application by reference. technical field [0003] The present invention relates to a vehicle fatigue relief device capable of relieving fatigue and suppressing drowsiness of a driver during vehicle driving. Background technique [0004] As a conventional mixed solvent, for example, the solvent described in Patent Document 1 is known. In the mixed solvent (liquid composition) of Patent Document 1, sesquiterpene alcohol as a low volatile component is contained in a solvent of fluoroether oil which is a perfluoroalkyl ether or a perfluoropolyether, and (fluoroether The value of (dissolution parameter of oil) - (dissolution parameter of sesquiterpene alcohol) is -8 to 0. As the sesquiterpene alcohol, it is described that cedrol is preferable. [0005] The above-...
