1. A drive assist device comprising:
- an approach degree calculator configured to calculate a first approach degree of a vehicle to an object in a vehicle travel direction and to calculate a second approach degree of the vehicle to the object in a direction that intersects the vehicle travel direction based on a relative velocity between the vehicle and the object; and
a drive assist control unit configured to control execution of drive assist based on the first approach degree and the second approach degreewherein the second approach degree is a value obtained by dividing a relative distance between the vehicle and the object in the direction that intersects the vehicle travel direction by the relative velocity between the vehicle and the object.
