Abstract:
The first yaw angle return control is started at a first start time when the first interruption condition is established. The actuator is controlled under the first yaw angle return control so that yaw angle at a first finish time becomes a value closer to yaw angle at the lane change start time compared with yaw angle at the first start time. The first finish time comes when a first control execution time passes from the first start time. The actuator is controlled under the second yaw angle return control so that yaw angle at a second finish time becomes a value closer to yaw angle at the lane change start time compared with yaw angle at the second start time. The second finish time comes when a second control execution time longer than the first control execution time passes from the second start time.

Claim (Index 1):
A lane change assist device comprising:\n a surrounding monitor configured to monitor a surrounding of a own vehicle; a lane recognition device configured to recognize a compartment line defining a side edge portion of a lane on which the own vehicle is traveling, and to detect a relative position of the own vehicle in a lane width direction with respect to the lane on which the own vehicle is traveling and detect a yaw angle with respect to an extension direction of the lane on which the own vehicle is traveling based on a positional relationship between the compartment line and the own vehicle; an actuator configured to be capable of generating a driving force for changing a steered angle of a steered wheel of the own vehicle; a lane change assist controller configured to start lane change assist control at a predetermined lane change start time, wherein the actuator is controlled under the lane change assist control so that the own vehicle makes a lane change from an original lane on which the own vehicle is traveling to a target lane which is adjacent to the original lane based on the relative position detected by the lane recognition device; a first interruption condition determiner configured to make the lane change assist controller interrupt the lane change assist control when a predetermined first interruption condition is established after the lane change assist control is started, the first interruption condition being established when it is determined that a probability of the own vehicle colliding with another vehicle travelling on the target lane is high based on a monitoring result of the surrounding monitor; a second interruption condition determiner configured to make the lane change assist controller interrupt the lane change assist control when a predetermined second interruption condition is established after the lane change assist control is started, the second interruption condition being established when the lane recognition device cannot detect the relative position; and a yaw angle return controller configured to execute first yaw angle return control and second yaw angle return control, wherein, the first yaw angle return control is started at a predetermined first start time when the first interruption condition is established, the actuator is controlled under the first yaw angle return control so that the yaw angle at a first finish time becomes a value closer to the yaw angle at the lane change start time compared with the yaw angle at the first start time, the first finish time coming when a predetermined first control execution time passes from the first start time, the second yaw angle return control is started at a predetermined second start time when the second interruption condition is established, the actuator is controlled under the second yaw angle return control so that the yaw angle at a second finish time becomes a value closer to the yaw angle at the lane change start time compared with the yaw angle at the second start time, the second finish time corning when a predetermined second control execution time longer than the first control execution time passes from the second start time.
