Abstract:
A first limiter limits a first target steering angle correspondence value by a first steering angle correspondence value guard which defines the upper limit value of the steering angle correspondence value and is larger than a steering angle correspondence value guard at lane change time and limits a first target steering angular velocity correspondence value by a first steering angular velocity correspondence value guard which defines the upper limit value of the steering angular velocity correspondence value and is larger than a steering angular velocity correspondence value guard at lane change time. An actuator controller for first yaw angle return control which is configured to control an actuator to operate a steering wheel so that steering angle correspondence value becomes a first target steering angle correspondence value and a steering angular velocity correspondence value becomes a first target steering angular velocity correspondence value.

Claim (Index 2):
The lane change assist device according to  claim 1 , further comprising:\n 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; a second target value calculator configured to calculate a second target steering angle which is a target value of the steering angle and a second target steering angular velocity which is a target value of the steering angular velocity, both the second target steering angle and the second target steering angular velocity being used for executing second yaw angle return control, the second yaw angle return control being started at a predetermined second start time when the second interruption condition is established, wherein 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 coming when a predetermined second control execution time which is longer than the first control execution time passes from the second start time; a second limiter configured to limit the second target steering angle by a second steering angle guard which defines an upper limit value of the steering angle and is smaller than the first steering angle correspondence value guard and to limit the second target steering angular velocity by a second steering angular velocity guard which defines an upper limit value of the steering angular velocity and is smaller than the first steering angular velocity correspondence value guard; and an actuator controller for second yaw angle return control configured to control the actuator to operate the steering wheel so that the steering angle becomes the second target steering angle and the steering angular velocity becomes the second target steering angular velocity, wherein the second target steering angle and the second target steering angular velocity are limited by the second limiter.
