Abstract

Disclosed is a vehicle travel safety device including: an object information detection unit that detects information regarding an object; a vehicle status information detection unit that detects information regarding the status of a vehicle; a collision probability determination unit that determines whether or not the vehicle may collide with the object, regarding which information is detected by the object information detection unit; and a collision avoidance assistance unit that performs collision avoidance assistance when the collision probability determination unit determines that the vehicle may collide with the object, and restricts collision avoidance assistance according to the status of steering performed by a driver of the vehicle.

Claims

1. A vehicle travel safety device comprising:

an object information detection unit that detects information regarding an object;

a vehicle status information detection unit that detects information regarding the status of a vehicle;

a collision probability determination unit that determines whether or not the vehicle may collide with the object, regarding which information is detected by the object information detection unit; and

a collision avoidance assistance unit that performs collision avoidance assistance when the collision probability determination unit determines that the vehicle may collide with the object, and restricts collision avoidance assistance according to the status of steering performed by a driver of the vehicle,

wherein when the driver of the vehicle turns the vehicle in a state where an object is detected in front of the vehicle, the collision avoidance assistance unit restricts collision avoidance assistance in response to an object different from the object in front of the vehicle.

2. The vehicle travel safety device according to claim 1,

wherein the collision avoidance assistance unit restricts collision avoidance assistance when there is an object in a steering direction depending on the status of steering performed by the driver of the vehicle.

4. The vehicle travel safety device according to claim 1,

wherein the collision avoidance assistance unit determines whether an object in a steering direction is a person or an object other than a person, and when it is determined that the object is a person, the collision avoidance assistance unit reduces the amount of restriction to collision avoidance assistance compared to when it is determined that the object is the object other than a person.

5. The vehicle travel safety device according to claim 1,

wherein the collision avoidance assistance unit reduces the amount of restriction to collision avoidance assistance to the extent that the amount of overlap between an object in the steering direction and the vehicle is large.

6. The vehicle travel safety device according to claim 1,

wherein the collision avoidance assistance unit restricts collision avoidance assistance when the driver turns the vehicle in a state where it is determined that there is an intersection.

7. The vehicle travel safety device according to claim 6,

wherein when the collision avoidance assistance unit detects any one of a crossing vehicle in front of the vehicle, right turn or left turn of a proceeding vehicle, a traffic signal, a crosswalk, and a roadside structure which is disposed such that two sides intersect each other, the collision avoidance assistance unit determines that there is an intersection.

3. (canceled)

8. A vehicle travel safety method comprising:

detecting information regarding an object using an object information detection unit;

detecting information regarding the status of a vehicle using a vehicle status information detection unit;

determining whether or not the vehicle may collide with the object, regarding which information is detected by the object information detection unit, using a collision probability determination unit; and

performing collision avoidance assistance when the collision probability determination unit determines that the vehicle may collide with the object, and restricting collision avoidance assistance according to the status of steering performed by a driver of the vehicle, using a collision avoidance assistance unit,

wherein when the driver of the vehicle turns the vehicle in a state where an object is detected in front of the vehicle, the collision avoidance assistance unit restricts collision avoidance assistance in response to an object different from the object in front of the vehicle.

9. A vehicle travel safety program causing a computer to execute:

a step of detecting information regarding an object using an object information detection unit;

a step of detecting information regarding the status of a vehicle using a vehicle status information detection unit;

a step of determining whether or not the vehicle may collide with the object, regarding which information is detected by the object information detection unit, using a collision probability determination unit; and

a step of performing collision avoidance assistance when the collision probability determination unit determines that the vehicle may collide with the object, and restricting collision avoidance assistance according to the status of steering performed by a driver of the vehicle, using a collision avoidance assistance unit,

wherein when the driver of the vehicle turns the vehicle in a state where an object is detected in front of the vehicle, the collision avoidance assistance unit restricts collision avoidance assistance in response to an object different from the object in front of the vehicle.
