Driving assistance device
First Claim
1. A driving assistance device comprising:
- a first driving assistance controller that executes first driving assistance control of automatic lane change control so as to perform lane changing automatically when a driver'"'"'s intention to change lanes has been detected;
a second driving assistance controller that executes second driving assistance control of different driving assistance control from the automatic lane change control; and
a deactivation controller that controls so as to deactivate the automatic lane change control and the second driving assistance control,wherein the deactivation controller;
deactivates the automatic lane change control when a control amount by the driver of a steering wheel, a brake pedal, or an accelerator pedal has exceeded a first deactivation threshold value during automatic lane change control;
deactivates the second driving assistance control when the control amount has exceeded a second deactivation threshold value during the second driving assistance control;
sets the first deactivation threshold value and the second deactivation threshold value so as to differ from each other; and
adjusts the first deactivation threshold value to a lower value as a vehicle speed becomes higher.

Abstract
A driving assistance system includes a deactivation controller that controls deactivation of Automatic Lane Change (ALC) control and a second driving assistance control (such as lane keeping control). During the ALC control, the deactivation controller deactivates the ALC central when, for example, a control amount by a driver of a steering wheel or the like has exceeded a first deactivation threshold value. During the second driving assistance control, the deactivation controller deactivates the second driving assistance control when, for example, the control amount has exceeded a second deactivation threshold value. The first deactivation threshold value and the second deactivation threshold value are set to differ from each other.

7. A driving assistance method comprising steps of:
-
executing, by a computer, a first driving assistance control of automatic lane change control so as to perform lane changing automatically when a driver'"'"'s intention to change lanes has been detected; executing, by the computer, a second driving assistance control of different driving assistance control from the automatic lane change control; deactivating, by the computer, the automatic lane change control when a control amount by the driver of a steering wheel, a brake pedal, or an accelerator pedal has exceeded a first deactivation threshold value during automatic lane change control; and deactivating, by the computer, the second driving assistance control when the control amount has exceeded a second deactivation threshold value during the second driving assistance control; and wherein the first deactivation threshold value and the second deactivation threshold value are set to be different from each other; and adjusting, by the computer, the first deactivation threshold value to a lower value as a vehicle speed becomes higher.
