Abstract

An object detection device can acquire information of an object in the vicinity of a host-vehicle for appropriate traveling assistance. An object detection device 1 includes a vehicle state detection section 2, an environmental situation acquisition section 3, a road information acquisition section 4, a detection control section 6, and a detection section 7. A host-vehicle state prediction section 61 acquires a target state of a host-vehicle 81. The detection section 7 detects an object. A parameter setting section 63 switches the detection characteristic of the object in the detection section 7 in accordance with the target state.

Claims

1. An object detection device which is mounted in a vehicle and detects an object in the vicinity of the host-vehicle, the object detection device comprising:

a host-vehicle state prediction unit that acquires a target state of the host-vehicle;

a detection unit that detects the object; and

a detection characteristic control unit that switches the detection characteristic of the object in the detection unit in accordance with the target state.

2. The object detection device according to claim 1, further comprising:

a road information acquisition unit that acquires information regarding a road; and

a determination unit that determines a possible collision form in the host-vehicle on the basis of the information regarding the road and the target state,

wherein the detection characteristic control unit switches the detection characteristic in accordance with the collision form.

3. The object detection device according to claim 1,

wherein the detection characteristic control unit switches the detection characteristic by adjusting a detection rate.

4. The object detection device according to claim 2,

wherein the detection characteristic control unit switches the detection characteristic by adjusting a detection rate.

5. The object detection device according to claim 3,

wherein, when a collision form is determined where the host-vehicle interferes with the route of another vehicle, the detection characteristic control unit switches the detection characteristic such that the detection rate in the detection unit increases.

6. The object detection device according to claim 4,

wherein, when a collision form is determined where the host-vehicle interferes with the route of another vehicle, the detection characteristic control unit switches the detection characteristic such that the detection rate in the detection unit increases.
