Lane change assist system
First Claim
1. A lane change assist system comprising:
- a host vehicle state detecting device that detects a traveling condition of a host vehicle;
a surrounding vehicle detecting device that detects other vehicle located around the host vehicle;
a lane detecting device that detects a lane around the host vehicle; and
a processing unit arranged to set a target lane to which the host vehicle change a traveling lane from the detected lane, to determine a start and an ending of a lane change assist, to set a predicted period for an evaluation of a lane change to the target lane, on the basis of a prediction, to obtain an appropriate speed range in which the host vehicle is capable of executing the lane change during the predicted period for each of gaps between other vehicles traveling on the target lane, and to select a target vehicle speed of the host vehicle from the appropriate speed range.

Abstract
A lane change assist system is comprised of a host vehicle state detecting device that detects a host vehicle traveling condition, a surrounding vehicle detecting device that detects other vehicle located around the host vehicle, a lane detecting device that detects a lane around the host vehicle, and a processing unit. The processing unit is arranged to set a target lane, to determine a period of a lane change assist, to set a predicted period for an evaluation of a lane change to the target lane based on a prediction, to obtain an appropriate speed range during the predicted period for each gap, and to select a target vehicle speed from the appropriate speed range.

15. A method of assisting a lane change of a host vehicle, comprising:
-
detecting a traveling condition of a host vehicle;
detecting other vehicle located around the host vehicle;
detecting a lane around the host vehicle;
executing a setting of a target lane to which the host vehicle moves and a determination of a start and an ending of a lane change assist;
setting a predicted period for an evaluation of a lane change to the target lane on the basis of a prediction;
obtaining an appropriate speed range in which the host vehicle is capable of executing the lane change during the predicted period for each of gaps between other vehicles traveling on the target lane; and
selecting a target vehicle speed of the host vehicle from the appropriate speed range.
