1. A driving assistance device comprising:
- a recognition controller configured to recognize lane markings and objects nearby a vehicle;
a lane change determination controller configured to determine whether or not a lane changing is possible based on a recognition result of the recognition controller;
an automatic lane change controller configured to, when the lane changing has been determined to be possible by the lane change determination controller and an operation to a direction indicator has been detected, execute an automatic lane change control of the vehicle in a direction indicated by the operation;
a torque sensor configured to detect a steering torque and a steering direction; and
a steering suppression controller configured to execute a steering suppression control,wherein the steering suppression controller does not execute the steering suppression control when the lane changing has been determined to be possible by the lane change determination controller and the torque sensor has detected a predetermined steering input torque or greater,wherein the automatic lane change controller switches the automatic lane change control in an enabled state when the lane changing has been determined to be possible by the lane change determination controller and a steering input torque that is detected by the torque sensor has been detected to be greater than or equal to a first torque based on a detection result of the torque sensor, andwherein, after detection of the steering input torque, the automatic lane change controller starts the automatic lane change control of the vehicle along the steering direction at a time when the steering torque has been detected to be a value less than or equal to a second torque which is less than the first torque.

Abstract
An Road Departure Mitigation (RDM) controller executes RDM control (steering suppression control). However, the RDM controller does not execute RDM control in cases in which lane changing has been determined to be possible by a Lane Change (LC) determination section and a torque sensor has detected a steering input of a predetermined amount or greater.
