Abstract
A lane change system that ensures safety is provided. This lane change system changes lanes by controlling steering in accordance with a path moving from a first lane in which the host vehicle is traveling to a second lane different from the lane in which the host vehicle is traveling, wherein the lane changing is stopped when there are any peripheral vehicles at high risk for collision in the second lane during a lane change from the first lane to the second lane.
Claims7
A lane change system for a host vehicle, comprising:
- a sensor;
- an actuator;
- and
- a vehicle control device configured to determine a command for the actuator, the vehicle control device further configured to:
- operate in a first mode for in-lane travel in which the vehicle control device controls steering to travel on a first path in a middle region of a first lane;
- operate in a second mode in which the vehicle control device determines a possibility of implementing a lane change from the first lane to a second lane adjacent to the first lane, and in which the vehicle control device controls steering to travel on a second path in a standby region of the first lane that is adjacent to the second lane;
- and
- operate in a third mode in which the vehicle control device changes lanes by controlling steering in accordance with a third path moving from the standby region of the first lane to the second lane, wherein
- when operating in the second mode, the vehicle control device determines not to shift to the third mode when the vehicle control device determines that there is a peripheral vehicle with a high collision risk in the second lane.
