Lane change assist device for a vehicle
First Claim
1. A lane change assist device for a vehicle, comprising:
- a meter electronic control unit (ECU) programmed to intermittently flash a turn signal;
a driving support electronic control unit (ECU) programmed to;
detect a lane change assist request in response to an operation performed on a turn signal lever by a driver;
start a lane change assist control to change lanes in which an own vehicle is traveling in response to the detection of the lane change assist request,wherein,the turn signal lever is configured to be able to be operated selectively between a first operation position which is a position at which the turn signal lever is rotated by a first stroke from a neutral position and at which the turn signal is intermittently flashed, and a second operation position which is a position at which the turn signal lever is rotated by a second stroke larger than the first operation position from the neutral position and at which the turn signal is intermittently flashed, in each of a right turn operation direction and a left turn operation direction, and to return to the neutral position when an operation force is released under a situation in which the turn signal lever positions at the first operation position,the driving support ECU is further programmed to;
measure a time period for which the turn signal lever is held at the first operation position and to detect the lane change assist request when the measured time period is equal to or longer than an assist request confirmation time period set in advance, andstop the lane change assist control when the turn signal lever is operated to the second operation position while the lane change assist control is being executed.

Abstract
When a duration time period in which a turn signal lever is held at a first operation position P1L (P1R) is equal to or larger than an assist request confirmation time period, a driving support ECU starts a lane change assist control. When an operation force is released under a situation in which the turn signal lever positions at the first operation position, the turn signal lever returns to a neutral position PN. When the driving support ECU starts the lane change assist control, the driving support ECU continues flashing a turn signal until a turn signal turning-off condition depending on a state of the lane change assist control is established. When the turn signal lever is performed at a second operation position P2L (P2R) while the lane change assist control is being executed, the lane change assist control is stopped.
