Sway detection device, sway detection method, and program

Abstract

To properly determine whether or not an own vehicle is staggering while traveling.SOLUTION: A stagger determination system 18 includes a stagger determination unit C6 that determines whether or not an own vehicle 1 is staggering while traveling. When a target TG exists around the own vehicle 1 which is traveling, if a face or line of sight of a driver of the own vehicle 1 is oriented to the target TG, a threshold alteration unit C5 alters a stagger determination threshold, which is employed in determining whether or not the own vehicle 1 is staggering while traveling, according to a positional relationship between the own vehicle 1 and target TG, or the stagger determination unit C6 suspends determination on whether or not the own vehicle 1 is staggering while traveling.SELECTED DRAWING: Figure 4

Claims

1. It is equipped with a sway detection unit that determines whether or not the vehicle is swaying while in motion, If a target exists around the vehicle while it is in motion, and the driver's face or line of sight is directed towards the target, the threshold changing unit changes the sway determination threshold used to determine whether the vehicle is swaying while in motion, according to the positional relationship between the vehicle and the target, or the sway determination unit stops determining whether the vehicle is swaying while in motion. The threshold changing unit is a sway detection device that changes the sway detection threshold according to the overlap amount, which is the amount of intrusion of the object into the planned driving area of ​​the vehicle, when the object exists around the vehicle while it is in motion and the driver's face or line of sight is directed towards the object.

2. The wobble determination device according to Claim 1, wherein the threshold changing unit changes the wobble determination threshold so that when the target exists around the vehicle in motion and the driver's face or line of sight is directed towards the target, the larger the overlap amount, the easier it is for the wobble determination unit to determine that there is no wobble while the vehicle is in motion.

3. A sway detection device comprising the step of determining whether or not the vehicle is swaying while in motion, When a target exists around the moving vehicle and the driver's face or line of sight is directed towards the target, the sway detection device includes the steps of changing the sway detection threshold used to determine whether the vehicle is swaying while moving, according to the positional relationship between the vehicle and the target, or stopping the determination of whether the vehicle is swaying while moving. A method for determining sway, wherein when the object exists around the vehicle while it is in motion, and the driver's face or line of sight is directed towards the object, the threshold for determining sway is changed according to the overlap amount, which is the amount of intrusion of the object into the vehicle's intended driving area.

4. The processor includes: A step to determine whether or not the vehicle is swaying while in motion, A program for performing the steps of changing a threshold for determining whether or not the vehicle is swaying while in motion, or stopping the determination of whether or not the vehicle is swaying while in motion, depending on the positional relationship between the vehicle and the target, when a target exists around the vehicle while it is in motion and the driver's face or line of sight is directed toward the target, A program that, when the object is present around the vehicle while it is in motion and the driver's face or line of sight is directed towards the object, changes the threshold for determining sway according to the overlap amount, which is the amount of intrusion of the object into the vehicle's intended driving area.
