Abstract

A classification determining unit determines classification of a stationary object that is detected by a stationary object detecting unit. In a case where it is determined that the stationary object is another vehicle, a judgment condition easing unit enlarges a margin area that is used when determining the need for collision avoidance support. When the margin area is enlarged, the probability for a user's own vehicle to interfere with the margin area increases. Stated otherwise, it becomes easier for a collision avoidance determining unit to determine that the collision avoidance support is needed.

First claim

What is claimed is:

1. A collision avoidance support device, comprising:
a stationary object detecting unit configured to detect a stationary object; and
a collision avoidance determining unit configured to determine a need for collision avoidance support in relation to the stationary object based on a predetermined judgment condition;
wherein, in a case where the collision avoidance determining unit determines that there is a need for collision avoidance support, the collision avoidance support device performs the collision avoidance support, the collision avoidance support device further comprising:
a classification determining unit configured to determine a classification of the stationary object;
a rider determining unit configured to determine that there is an occupant inside the stationary object;
a judgment condition easing unit configured to, in a case where the classification determining unit determines that the stationary object is a vehicle, ease the judgment condition based on a judgment result made by the rider determining unit, and thereby make it easier for the collision avoidance determining unit to determine that the collision avoidance support is needed; and
a collision avoidance operating unit including an automatically operated braking device and an automatically operated steering device,
wherein, in a case where the rider determining unit determines that there is an occupant riding in the vehicle, the judgment condition easing unit eases the judgment condition, and thereby makes it easier for the collision avoidance determining unit to determine that the collision avoidance support is needed, and
wherein, in a case where the collision avoidance determining unit determines a need for collision avoidance support, the collision avoidance operating unit operates at least one of the automatically operated braking device and the automatically operated steering device to implement the collision avoidance support.

2. A collision avoidance support device, comprising:
a stationary object detecting unit configured to detect a stationary object; and
a collision avoidance determining unit configured to determine a need for collision avoidance support in relation to the stationary object based on a predetermined judgment condition:
wherein, in a case where the collision avoidance determining unit determines that there is a need for collision avoidance support, the collision avoidance support device performs the collision avoidance support, the collision avoidance support device further comprising:
a classification determining unit configured to determine a classification of the stationary object;
an engine operation determining unit configured to determine a state of an engine of the stationary object;
a judgment condition easing unit configured to, in a case where the classification determining unit determines that the stationary object is a vehicle, ease the judgment condition based on a judgment result made by the engine operation determining unit, and thereby make it easier for the collision avoidance determining unit to determine that the collision avoidance support is needed,

wherein the judgment condition easing unit eases the judgment condition depending on the state of the engine of the vehicle determined by the engine operation determining unit, and thereby makes it easier for the collision avoidance determining unit to determine that the collision avoidance support is needed.

3. The collision avoidance support device according to claim 2 , wherein, the engine operation determining unit determines whether the engine of the vehicle is stopped, and wherein, in a case where the engine operation determining unit judges the engine of the vehicle to be stopped, the judgment condition easing unit eases the judgment condition in a width direction of the vehicle, and thereby makes it easier for the collision avoidance determining unit to determine that the collision avoidance support is needed as a precaution for a possible opening of a door of the vehicle.

4. The collision avoidance support device according to claim 3 , wherein, in a case where the engine operation determining unit judges that an engine is within a predetermined time period since having been stopped, the judgment condition easing unit eases the judgment condition in the width direction of the vehicle, and thereby makes it easier for the collision avoidance determining unit to determine that the collision avoidance support is needed.

5. The collision avoidance support device according to claim 2 , wherein the engine operation determining unit determines whether the engine of the vehicle is being started, and wherein, in a case where the engine operation determining unit judges that the engine of the vehicle is being started, the judgment condition easing unit eases the judgment condition in a traveling direction of the vehicle, and thereby makes it easier for the collision avoidance determining unit to determine that the collision avoidance support is needed as a precaution for the possibility that the vehicle is about to move.

6. The collision avoidance support device according to claim 5 , wherein in a case where the engine operation determining unit judges that it is within a predetermined time period since the engine of the vehicle was started, the judgment condition easing unit eases the judgment condition in the traveling direction of the vehicle, and thereby makes it easier for the collision avoidance determining unit to determine that the collision avoidance support is needed.

7. A collision avoidance support device, comprising:
a stationary object detecting unit configured to detect a stationary object; and
a collision avoidance determining unit configured to determine a need for collision avoidance support in relation to the stationary object based on a predetermined judgment condition;
wherein, in a case where the collision avoidance determining unit determines that there is a need for collision avoidance support, the collision avoidance support device performs the collision avoidance support, the collision avoidance support device further comprising:
a classification determining unit configured to determine a classification of the stationary object;
a judgment condition easing unit configured to, in a case where the classification determining unit determines that the stationary object is a vehicle, ease the judgment condition, and thereby make it easier for the collision avoidance determining unit to determine that the collision avoidance support is needed; and

at least one of a vehicle type determining unit configured to determine a movement amount of a door of the vehicle, a gear range determining unit configured to determine whether a gear of the vehicle is in a driving range, and a steering input determining unit configured to determine whether a steering handle of the vehicle is currently being operated,
wherein the judgment condition easing unit eases the judgment condition, and thereby makes it easier for the collision avoidance determining unit to determine that the collision avoidance support is needed in at least one of the cases where the movement amount of the door of the vehicle determined by the vehicle type determining unit is large in a width direction of the vehicle, where the gear of the vehicle determined by the gear range determining unit is in a driving range, and where the steering input is judged by the steering input determining unit as being made with respect to the vehicle.
