Abstract
An object is identified by an on-board camera and a relative speed of the vehicle and the object is acquired. If the object is a two-wheel vehicle and the relative speed is lower than the vehicle speed, the relative speed is set as a collision speed. If the object is an object other than a two-wheel vehicle, the vehicle speed is set as the collision speed. Using the set collision speed, an effective mass is computed and collision determination is executed.
Claims7
A collision detection device for a vehicle, comprising:
- a vehicle speed detection unit that detects a vehicle speed of the vehicle;
- a collision prediction unit that predicts a collision between the vehicle and an object, the object including a two-wheel vehicle being ridden by a two-wheel vehicle rider;
- an effective mass computation unit that,
- if a collision with a two-wheel vehicle is predicted by the collision prediction unit, computes an effective mass of the object on the basis of a speed that is lower than the vehicle speed detected by the vehicle speed detection unit, and
- if a collision with the object other than a two-wheel vehicle is predicted, computes the effective mass of the object on the basis of the vehicle speed detected by the vehicle speed detection unit;
- and
- a signal output unit that, if the effective mass of the object computed by the effective mass computation unit is at least a threshold value, outputs a signal that activates a protection device that protects people outside the vehicle including pedestrians and two-wheel vehicle riders.
