Abstract

A steering device, a method for authenticating a driver, and a vehicle are disclosed. The steering device is equipped with an identification information acquisition unit. When a driver takes a position for operating the steering device, namely, a home position to the steering device, the identification information acquisition unit acquires a venous pattern of the driver as identification information. The steering device then outputs the identification information.

Claims

1. A steering device operated by a driver when the driver drives a vehicle, comprising:

an identification information acquisition unit, which automatically acquires identification information of the driver when the driver takes a home position for operating the steering device without need for a particular action of the driver for authorizing acquisition of identification information, mounted in a position at which an inside of a forearm of the driver, leading to the palm of a hand of the driver, faces when the driver assumes the home position to operate the steering device so that the identification acquisition unit detects the venous pattern of the inside of the forearm of the hand and acquires the venous pattern as the identification information, movable means shaped to receive the palm of the hand of the driver for gripping means so that the displacement of the movable means so that said steering device converts a displacement of said steering device to an electrical signal representative of said identification information;

and an identification information output unit for outputting the identification information.

2. A steering device according to claim 1, wherein the identification information acquisition unit detects the running pattern of blood vessels and acquires the blood vessel running pattern as the identification information.

3. A steering device according to claim 2, wherein the identification information acquisition unit comprises an infrared emitter for emitting an infrared light beam, and an infrared detector for detecting infrared light reflected in response to the infrared light beam emitted from the infrared emitter.

4. A steering device according to claim 1, wherein the identification information acquisition unit is mounted in a position toward which the wrist or the palm of the hand of the driver faces when the driver assumes the home position to operate the steering device.

5. A steering device according to claim 1, wherein the identification information acquisition unit automatically acquires the identification information in a non-contact state thereof with the driver without need for a particular action of the driver for authorizing acquisition of said identification information.

6. A method of authenticating a driver, comprising the steps of:

automatically acquiring, as identification information of the driver, the running pattern of a venous pattern of blood vessels of the inside of a forearm of the hand of the driver based on infrared light that is reflected from the inside of the forearm of the driver when an infrared light beam is directed to the inside of the forearm of the driver who assumes a home position to operate an operation device of a vehicle, without need for a particular action of the driver for authorizing acquisition of identification information;

providing movable means shaped to receive the palm of the hand of the driver for gripping means so that the displacement of the movable means is an operational amount for producing an electrical signal related to said identification information, and authenticating the driver based on the identification information.

7. A method according to claim 6, further comprising the step of performing a particular process on a per driver basis in response to the result of the authentication.

8. A vehicle comprising:

a steering device which receives an operation input by a driver to convert an operation amount into an electrical signal,

identification information acquisition means which is mounted on the steering device, at a position at which an inside of a forearm of the driver, leading to the palm of a hand of the driver, faces when the driver assumes a home position to provide the operation input to said steering device, and, as identification information of the driver, detects a venous pattern of blood vessels of the inside of a forearm of the hand of the driver based on infrared light that is reflected from the forearm of the hand of the driver when an infrared light beam is directed thereto, without a need for a particular action of the driver for authorizing obtaining said identification information,

movable means shaped to receive the palm of the hand of the driver for gripping means so that the displacement of the movable means is operational amount, and

authenticating means for authenticating the driver based on the identification information.

9. A vehicle according to claim 8, further comprising processor means for performing a particular process on a per driver basis in response to the result of the authentication provided by the authenticating means.

10. A vehicle according to claim 8, wherein the operation means is a steering device which converts the operational amount into an electrical signal, further including fixed means mounted close to the position of operation,

and movable means shaped to receive the palm of the hand of the driver for gripping means so that the displacement of the movable means is the operational amount.
