Abstract

A driving support system includes a first, a second, and a third imaging units capturing images of front view, right rear view, and left rear view from the vehicle, respectively, a turn signal indicator operation detection unit detecting an operation state of a turn signal indicator of the vehicle, a steering control unit controlling a steering operation of the vehicle, a lane keeping support unit performing driving support for lane keeping, and a lane change support unit performing a lane change by instructing the lane keeping support unit to cancel lane keeping based on the the image of the rear view from the vehicle when an operation of the turn signal indicator is detected, and withholding a lane change and wait until there is no obstructing vehicle and then cancelling withholding of the lane change when it is determined that there is no obstructing vehicle.

Claims

1. A driving support system comprising:

a first imaging unit configured to capture an image of a front view from a vehicle;

a second imaging unit configured to capture an image of a right rear view from the vehicle;

a third imaging unit configured to capture an image of a left rear view from the vehicle;

a turn signal indicator operation detection unit configured to detect an operation state of a turn signal indicator of the vehicle;

a steering control unit configured to control a steering operation of the vehicle;

a lane keeping support unit configured to recognize a lane, in which a host vehicle is to travel, from the image of the front view captured by the first imaging unit and performs driving support for lane keeping by controlling the steering operation using the steering control unit so that the vehicle travels while remaining in the lane; and

a lane change support unit configured to search for a vehicle as an obstacle to a lane change from the image of the rear view from the vehicle, which has been captured by the second or third imaging unit, corresponding to a direction detected by the turn signal indicator operation detection unit when an operation of the turn signal indicator is detected by the turn signal indicator operation detection unit during driving support for lane keeping, to perform a lane change by instructing the lane keeping support unit to change a lane being used to an adjacent lane in a direction detected by the turn signal indicator operation detection unit when it is determined that there is no obstructing vehicle, and to withhold a lane change and wait until there is no obstructing vehicle and then cancel withholding of the lane change when it is determined that there is no obstructing vehicle.

2. The driving support system according to claim 1, further comprising:

a speed detection unit configured to detect a speed of the vehicle,

wherein a driving support operation of the lane change support unit is executed when the speed detected by the speed detection unit is greater than or equal to a predetermined speed.

3. The driving support system according to claim 2, further comprising:

an alarm output unit configured to output an alarm indicating that a lane change is not possible when a waiting time until there is no obstructing vehicle exceeds a predetermined time.

4. The driving support system according to claim 1, further comprising:

an alarm output unit configured to output an alarm indicating that a lane change is not possible when a waiting time until there is no obstructing vehicle exceeds a predetermined time.
