Abstract:
A yaw angle return controller is configured to end first yaw angle return control at a predetermined time when a value which is calculated by adding yaw angle detected by a lane recognition device at a predetermined time and an estimated yaw angle change amount is the same as yaw angle at lane change start time under a state where the first yaw angle return control is being executed. The predetermined time comes after the first start time and before the first finish time. The estimated yaw angle change amount is calculated by multiplying the yaw rate detected by a yaw rate sensor at the predetermined time by a predetermined time period for foreseeing.

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, the lane recognition device being a camera sensor; a yaw rate sensor configured to detect a yaw rate of 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 brought 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; and a yaw angle return controller configured to execute first 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 yaw angle return controller executes the first yaw angle return control to bring the actuator under a feed forward 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 yaw angle return controller is configured to end the first yaw angle return control at a predetermined time when a value which is calculated by adding the yaw angle detected by the lane recognition device at the predetermined time and an estimated yaw angle change amount is the same as the yaw angle at the lane change start time under a state where the first yaw angle return control is being executed, the predetermined time coming after the first start time and before the first finish time, the estimated yaw angle change amount being calculated by multiplying the yaw rate detected by the yaw rate sensor at the predetermined time by a predetermined time period for foreseeing.
