1. A driving assist apparatus for a vehicle comprising:

  • a detecting portion that detects a deflection angle that is an angle formed between a direction of the vehicle at a present position and a direction of the vehicle at a target position;

    a setting portion that sets a basic path that extends until the deflection angle is changed to a state of 0 by steering the vehicle at a predetermined steering rate;

    a computing portion that computes a target path that extends from the present position to the target position based on the basic path;

    a driving assist portion that performs a driving assist by using the target path; and

    a transforming portion that re-calculates a basic path during the driving assist, and that determines whether it is possible to set a path that reaches the target position through similarity transformation of the basic path based on a relationship between the present position of the vehicle and the target position of the vehicle, and that, if it is possible to set a path, re-sets a path that reaches the target position through similarity transformation.
