Technical Field

The present invention relates to a vehicle protection device that protects a protected object such as a pedestrian when a vehicle collides with the protected object, and a vehicle including the vehicle protection device.

Background

Conventionally, as a vehicle protection device that reduces an impact on a protection object (pedestrian) by deploying an airbag when a vehicle collides with the protection object, for example, vehicle pedestrian protection devices described in patent documents 1 and 2 are known.

The pedestrian protection apparatus for a vehicle described in patent document 1 prevents a pedestrian from sliding up rearward in the vehicle by deploying an airbag having a slide-up prevention mechanism upward from a front bumper at the time of a collision.

The injury reduction device described in patent document 2 prevents a pedestrian from falling down by detecting the movement of the pedestrian on the hood and performing acceleration/deceleration/steering using a camera after absorbing the impact of the pedestrian using an airbag deployed on a front windshield and the hood (bonnet).

Disclosure of Invention

The vehicle protection devices described in patent documents 1 and 2 can absorb an impact of a protection object (pedestrian) by an airbag or a hood at the time of a collision. However, in the vehicle protection device, when the object to be protected is protected by the airbag or the hood, the difference in the object to be protected by the hood or the airbag is not considered.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a vehicle protection device capable of protecting a protection object such as a pedestrian from a vehicle collision, and a vehicle including the vehicle protection device.

In order to solve the above problem, a vehicle protection device according to claim 1 includes: a protection device that protects a protection object that collides with a vehicle; a measuring device that measures an image of the protection object and a distance of the protection object from the vehicle; and a control device that causes the protection device to operate in different modes according to the size of the protected object.

The vehicle of the invention 2 is a vehicle provided with the vehicle protection device of the invention 1.

ADVANTAGEOUS EFFECTS OF INVENTION

According to the present invention, it is possible to realize a vehicle protection device capable of protecting a protection object such as a pedestrian in response to a collision with a vehicle, and a vehicle including the vehicle protection device.
