Abstract

A setting unit dynamically sets a first area and a second area on a touch sensor mounted on a grip portion that a driver grips on a steering wheel. A first detector is configured to detect a state where a first area in a touch sensor mounted on a grip portion that a driver grips on a steering wheel is touched. A second detector is configured to detect a state where a particular input operation is performed on a second area located on the upper side of the first area in the touch sensor. A controller is configured to control an operation target device to be operated with the touch sensor according to the particular input operation when the first detector detects the state where the first area is touched and the second detector detects the state where the particular input operation is performed.

First claim

What is claimed is:

1. A control apparatus for controlling an operation target device in a vehicle, the vehicle including a touch sensor mounted on a grip portion that a driver grips on a steering wheel, comprising:
a detector configured to determine whether a predetermined area or greater of the touch sensor is touched, and determine that the touch sensor is touched by a palm of the driver when the predetermined area or greater of the touch sensor is touched; and
a setting unit configured to set dynamically a grip detection area on the touch sensor, depending on a position on the touch sensor where the driver grips, when the detector determines that the touch sensor is touched by the palm, the grip detection area being a first area in a circumferential direction of the touch sensor including a portion where the palm makes contact, and to set an operation detection area for detecting an input operation performed with a thumb or an index finger of the driver, the operation detection area being a second area on an upper side of the first area in the circumferential direction;
wherein the detector is configured to detect a state where a particular input operation for controlling an operation target device to be operated with the touch sensor is performed on the operation detection area; and
wherein the control apparatus further comprises a controller configured to control the operation target device according to the particular input operation when the detector detects a state where the grip detection area is touched by the palm and the particular input operation is performed on the operation detection area.

2. The control apparatus for controlling an operation target device in a vehicle according to claim 1 , wherein the operation detection area includes a front side facing the driver and a rear side, the detector detects a state where the particular input operation has been performed on the front side by the thumb and a state where the particular input operation has been performed on the rear side by the index finger.

3. A method for controlling an operation target device in a vehicle, the vehicle including a touch sensor mounted on a grip portion that a driver grips on a steering wheel comprising:
determining whether a predetermined area or greater of the touch sensor is touched;
determining that the touch sensor is touched by a palm of the driver when the predetermined area or greater of the touch sensor is touched;
setting dynamically a grip detection area on the touch sensor, depending on a position on the touch sensor where the driver grips, when it is determined that the touch sensor is touched by the palm, the grip detection area being a first area in a circumferential direction of the touch sensor including a portion where the palm makes contact;
setting an operation detection area for detecting an input operation performed with a thumb or an index finger of the driver, the operation detection area being a second area on an upper side of the first area in the circumferential direction;
determining whether a particular input operation for controlling an operation target device to be operated with the touch sensor is performed on the operation detection area; and
controlling the operation target device according to the particular input operation when it is determined that the first grip detection area is touched by the palm and the particular input operation is performed on the operation detection area.

4. The method for controlling an operation target device in a vehicle according to claim 3 , wherein the operation detection area includes a front side facing the driver and a rear side,
the determining whether the particular input operation for controlling the operation target device is performed includes determining whether the particular input operation by the thumb is performed on the front side and determining whether the particular input operation by the index finger is performed on the rear side.
