Lane change assist device for a vehicle
First Claim
1. A lane change assist device for a vehicle, comprising:
- an operator configured to be operated by a driver when the driver when the driver requests a lane change assist;
a surrounding monitor for monitoring a surrounding of an own vehicle; and
a controller configured to;
detect the lane change assist request from the driver when the operator is operated by the driver;
accept the lane change assist request to start lane change assist control for changing lanes, when the controller determines that the own vehicle can safely change lanes in which the own vehicle travels under a situation in which the controller has detected the lane change assist request; and
detect a non-operation state in which the operator is not operated by the driver;
accept the lane change assist request when a requisite condition is established, the requisite condition being a condition which is set to be established when the controller detects that the operator is operated under a situation in which the contoller has detected the non-operation state;
execute, when the controller accepts the lane change assist request, the lane change assist control to have the own vehicle change lanes from a current lane in which the own vehicle is currently travelling to a lane immediately adjacent to the current lane; and

Abstract
A driving support ECU detects a shallow pressing operation monitoring signal of the turn signal lever is turned off (S14: Yes). When a timer value Tx representing an ON duration time period in which the shallow pressing operation monitoring signal is continued to be turned on reaches an assist request confirmation time period Tref (S19: Yes) and an LCA start condition is established (S20: Yes) after the detection of the shallow pressing operation monitoring signal, the driving support ECU starts LCA. The driving support ECU does not determines, until the LCA is completed, whether or not the shallow pressing operation monitoring signal is turned off. The driving support ECU restarts processes from S11 after the LCA is completed. Therefore, even if the shallow pressing operation is continued to be performed, the LCA is not executed further.
