Driving assist apparatus and method for vehicle

The apparatus has an electronic control unit (1) that sets a basic path that extends until a deflection angle is changed to a state 0 by steering a vehicle at a preset steering rate. A transforming unit determines if it is possible to set a path that reaches a target position through similarity transformation of the basic path based on a relationship between a present position and the target position of the vehicle. An independent claim is also included for a driving assist method.
