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 2):
The lane change assist device according to  claim 1 , wherein,\n the lane recognition device is a camera sensor, the lane change assist controller comprises:\n a target trajectory function calculator configured to calculate a target trajectory function representing a target lateral position which is a target position of the own vehicle in the lane width direction according to an elapsed time from the lane change start time; \n a target lateral position calculator configured to sequentially calculate the target lateral position during execution of the lane change assist control based on the target trajectory function and the elapsed time; \n a target state amount calculator configured to sequentially acquire vehicle speed of the own vehicle and to sequentially calculate target yaw state amount which is a target value relating to movement for changing a direction of the own vehicle based on the target trajectory function, the elapsed time and the vehicle speed during execution of the lane change assist control; and \n the lane change assist controller configured to control the actuator based on the target lateral position and the target yaw state amount, \n the yaw angle return controller is configured to:\n calculate a first integral value acquired by integrating a target curvature which is a curvature of a path of the own vehicle and is defined by the target trajectory function with respect to time from the lane change start time to the first start time, calculate a first target control amount which is a target control amount between the first start time and the first finish time based on a value corresponding to the first integral value, and control the actuator based on the first target control amount during execution of the first yaw angle return control; and \n calculate a second integral value acquired by integrating the target curvature with respect to time from the lane change start time to the second start time, calculate a second target control amount which is a target control amount between the second start time and the second finish time based on a value corresponding to the second integral value, and control the actuator based on the second target control amount during execution of the second yaw angle return control.
