Abstract

The object of the invention is to provide a vehicle key capable of preventing the drunken driving. The vehicle key comprises a key portion with the forward end portion thereof insertable into the key hole of the vehicle such as a train, a motor bike and an automobile, a holder portion arranged at the base end portion of the key portion, a projection member projected from the holder portion along the key portion, a spring for urging the projection member in the direction of projection, a breath component detection means for detecting the alcohol contained in the breath of the user, and a lock mechanism for locking the projection member in a projected state in accordance with the detection result of the breath component detection means.

Claims

1. A vehicle key capable of being inserted into a key hole of a vehicle including a train, a motorbike and an automobile, and used for starting a prime mover of the vehicle, the key comprising:

a key portion having a forward end portion insertable into the key hole of the vehicle;

a holder portion for holding a base end portion of the key portion;

a breath component detection means for detecting at least one of alcohol and drug contained in a breath of a user; and

an insert prevention means comprising a projection member projectable from the holder portion so as to prevent insertion of the key portion into the key hole of the vehicle, the insert prevention means being adapted to accommodate the projection member in the holder portion in accordance with a detection result of the breath component detection means.

2. The vehicle key according to claim 1, wherein

the insert prevention means includes:

a the projection member projectable from the holder portion along the key portion;

a spring for urging the projection member in a direction of the projection; and

a lock mechanism for locking and maintaining the projection member in a projected state, and

the lock mechanism is adapted to unlock the projection member in accordance with the detection result of the breath component detection means.

3. The vehicle key according to claim 2, wherein

the lock mechanism includes:

a plunger configured as a member engageable with a depression on a side surface of the projection member, and disposed on the holder portion linearly movably from an engaging position, at which the plunger engages with the depression of the projection member, to an evacuation position, at which the plunger fails to engage with the depression of the projection member, and

a drive means for moving the plunger from the engaging position to the evacuation position in accordance with the detection result of the breath component detection means.

4. The vehicle key according to claim 3, wherein

the breath component detection means includes:

at least one of an alcohol sensor and a drug sensor, and

a control unit for controlling an on/off operation of the drive means in accordance with an output signal of the at least one of the alcohol sensor and the drug sensor.

5. The vehicle key according to claim 1, wherein the projection member is disposed on the key portion.

12. The vehicle key according to claim 3, further comprising:

a sensing means for reading a physical feature of the user, wherein

the breath component detection means includes;

at least one of an alcohol sensor and a drug sensor, and

a control unit for authenticating the user based on sensing data of the sensing means, and for performing at least one of alcohol determination and drug determination to determine whether at least one of alcohol and drug is contained in the breath of the user in accordance with an output signal of the at least one of the alcohol sensor and the drug sensor, and

the control unit has a function of controlling an on/off operation of one of the drive means, the pressure means, and the signal output means, either in a case where the user is not authenticated as a result of the authentication, or in a case where at least one of alcohol and drug is determined to be contained in the breath of the user as a result of the at least one of alcohol determination and drug determination.

13. The vehicle key according to claim 12, wherein

the control unit has a function of performing the at least one of alcohol determination and drug determination within a predetermined period of time before and after the authentication.

14. The vehicle key according to claim 13, wherein

the sensing means is one of a voice detection means for detecting voice of the user, and an image pickup means for picking up an image of an iris of an eye of the user.

15. The vehicle key according to claim 2, further comprising:

a position detection means for detecting that the projection member is accommodated in the holder portion; and

a memory unit for recording a detection result of the position detection means.

16. The vehicle key according to claim 1, further comprising a GPS (Global Positioning System) transmitter.

6-8. -8. (canceled)

9. A vehicle key for outputting a start permit signal to a vehicle including a train, a motorbike, and an automobile, and for either starting a prime mover of the vehicle or setting the prime mover in a ready state for starting, the key comprising:

a signal output means for outputting the start permit signal;

a breath component detection means for detecting at least one of alcohol and drug contained in a breath of a user, and

a prevention means for preventing the start permit signal outputted by the signal output means from arriving at the vehicle in accordance with a detection result of the breath component detection means.

10. The vehicle key according to claim 9, wherein

the prevention means includes:

a shield means for shielding the start permit signal output from the signal output means; and

a drive means for moving the shield means from a shield position, at which the start permit signal of the signal output means is shielded, to an evacuation position, at which the start permit signal fails to be shielded, in accordance with the detection result of the breath component detection means.

11. The vehicle key according to claim 9, wherein

the breath component detection means includes:

at least one of an alcohol sensor and a drug sensor; and

a control unit for controlling an on/off operation of one of the signal output means and the drive means, in accordance with an output signal of the at least one of the alcohol sensor and the drug sensor, thereby functioning as the prevention means.

27. The vehicle key according to claim 9, further comprising:

a sensing means for reading a physical feature of the user, wherein

the breath component detection means includes;

at least one of an alcohol sensor and a drug sensor; and

a control unit for authenticating the user based on sensing data of the sensing means, and for performing at least one of alcohol determination and drug determination to determine whether at least one of alcohol and drug is contained in the breath of the user in accordance with an output signal of the at least one of the alcohol sensor and the drug sensor, and

the control unit has a function of controlling an on/off operation of one of the drive means, the pressure means, and the signal output means, either in a case where the user is not authenticated as a result of the authentication, or in a case where at least one of alcohol and drug is determined to be contained in the breath of the user as a result of the at least one of alcohol determination and drug determination.

29. The vehicle key according to claim 9, further comprising a GPS (Global Positioning System) transmitter.
