Abstract

A vehicle operation input apparatus includes: a display having a screen; and a control unit configured to determine whether or not a hand of a driver has been removed from a steering wheel, and after determining that the hand of the driver has been removed from the steering wheel in a situation where an operation menu is not displayed on the screen, control the display such that the operation menu is displayed on the screen.

Claims

1. A vehicle operation input apparatus comprising:

a display having a screen;

a sensor configured to detect a hand position; and

a control unit configured to determine whether or not a hand of a driver has been removed from a steering wheel, and after determining that the hand of the driver has been removed from the steering wheel in a situation where an operation menu is not displayed on the screen, control the display such that the operation menu is displayed on the screen,

wherein the display is a touch panel display configured to detect touch, and

wherein the control unit is configured to determine whether or not a host vehicle is traveling on a straight road or whether or not a road ahead of the host vehicle in an advancement direction is a straight road, and after determining that the hand of the driver has been removed from the steering wheel and the host vehicle is traveling on a straight road in a situation where the operation menu is not displayed on the screen or determining that the hand of the driver has been removed from the steering wheel and the road ahead of the host vehicle in the advancement direction is a straight road in a situation where the operation menu is not displayed on the screen, control the display such that the operation menu is displayed on the screen.

2. The vehicle operation input apparatus according to claim 1, wherein, even if the hand of the driver is determined to have been removed from the steering wheel in a situation where the operation menu is not displayed on the screen, the control unit is configured to control the display such that display of the operation menu is suppressed after determining that the host vehicle is traveling on a curved road or a bend, or the road ahead of the host vehicle in the advancement direction is a curved road or a bend.

3. The vehicle operation input apparatus according to claim 1, wherein the control unit is configured to obtain map information and host vehicle position information, and determine whether or not the host vehicle is traveling on a straight road or whether or not the road ahead of the host vehicle in the advancement direction is a straight road on the basis of the obtained map information and host vehicle position information.

4. A vehicle operation input apparatus comprising:

a display having a screen;

a sensor configured to detect a hand position; and

a control unit configured to determine whether or not a hand of a driver has been removed from a steering wheel, and after determining that the hand of the driver has been removed from the steering wheel in a situation where an operation menu is not displayed on the screen, control the display such that the operation menu is displayed on the screen,

wherein the display is a touch panel display configured to detect touch, and

wherein the control unit is configured to determine whether or not a driving load on the driver is at or below a predetermined level, and after determining that the hand of the driver has been removed from the steering wheel and the driving load on the driver is at or below the predetermined level in a situation where the operation menu is not displayed on the screen, control the display such that the operation menu is displayed on the screen, wherein the control unit is configured to determine the driving load on the driver on the basis of vehicle speed information and steering angle information.

5. The vehicle operation input apparatus according to claim 4, wherein, even if the hand of the driver is determined to have been removed from the steering wheel in a situation where the operation menu is not displayed on the screen, the control unit is configured to control the display such that display of the operation menu is suppressed after determining that the driving load on the driver is larger than the predetermined level.

6. A control method for a vehicle operation input apparatus, comprising:

determining whether or not a hand of a driver has been removed from a steering wheel by detection of a hand position by a sensor; and

after determining that the hand of the driver has been removed from the steering wheel in a situation where an operation menu is not displayed on a screen of a display, controlling the display such that the operation menu is displayed on the screen,

determining whether or not a driving load determined on the basis of vehicle speed information and steering angle information on the driver is at or below a predetermined level, and after determining that the hand of the driver has been removed from the steering wheel and the driving load on the driver is at or below the predetermined level in a situation where the operation menu is not displayed on the screen, controlling the display such that the operation menu is displayed on the screen,

wherein the display is a touch panel display configured to detect touch.

7. The method according to claim 6, wherein even if the hand of the driver is determined to have been removed from the steering wheel in a situation where the operation menu is not displayed on the screen, controlling the display such that display of the operation menu is suppressed after determining that the driving load on the driver is larger than the predetermined level.
