Abstract

A vehicular awakening detection device 10 includes pressure sensors 48 provided in a + side paddle shift 46R and/or a − side paddle shift 46L which is able to be operated by a driver in a vehicle. The pressure sensor 48 is used for determining the degrees of awakening of a driver by making the driver to operate the + side paddle shift 46R and/or the − side paddle shift 46L.

Claims

1. A vehicular awakening detection device comprising:

an awakening degree detection sensor provided in a movable member which is able to be operated by a driver in a vehicle and configured to determine degrees of awakening of the driver by making said driver to operate said movable member.

2. The vehicular awakening detection device according to claim 1, further comprising:

a device provided in the vehicle and configured to provide guidance to the driver regarding an operation of the movable member, wherein

the awakening degree detection sensor is configured to detect the operation of the movable member by the driver and to determine the degrees of awakening of the driver based on a detection result of the operation of the movable member in response to the guidance given to the driver.

3. The vehicular awakening detection device according to claim 1,

wherein said movable member is a paddle shift which is provided in a vicinity of a steering wheel of the vehicle for the driver to operate a gear shift, and

said awakening degree detection sensor is a pressure sensor provided in the paddle shift.

4. The vehicular awakening detection device according to claim 3,

wherein said pressure sensor comprises a variable resistor of which a resistance value is changed in accordance with said operation, and

said awakening degree detection sensor determines the degrees of awakening of said driver based on one or both of:

said operation speed detected from a difference between resistance values detected at an interval of a predetermined sampling period; and

an operating force detected from a maximum value or a minimum value of the resistance value during said operation.

5. The vehicular awakening detection device according to claim 3,

wherein said paddle shift comprises:

a first spring member which generates a first reaction force in response to an operation of the paddle shift in an operation range of a normal shift switch; and

a second spring member which generates a second reaction force in response to the operation of the paddle shi ft in an operation range which exceeds the operation range of said normal shift switch, the second spring member having a spring constant greater than that of said first spring member.

6. The vehicular awakening detection device according to claim 3,

wherein said paddle shift has:

a left side paddle shift provided on a left side of said steering wheel; and

a right side paddle shift provided on a right side of said steering wheel, and

said awakening degree detection sensor determines the degrees of awakening of said driver in a state where both said left side paddle shift and said right side paddle shift are operated at the same time.
