Parking assist system with image obtaining means and displaying means

A parking assist system comprising:

• image obtaining means for obtaining an image of a view from a vehicle;
• displaying means for displaying the image obtained by the image obtaining means in a monitor display provided in the vehicle;
• inputting means for inputting a target parking position, at which the vehicle is parked, on the monitor display;
• detecting means for detecting a relative relationship between the vehicle and the target parking position;
• and
• judging means for judging that the vehicle located at an original position can be parked at the target parking position based upon satisfaction of all of the following conditions:
• (1) a straight line extending from a coordinate (X0, Z0) at a parking angle (θ) relative to the Z axis intersects the X axis within a negative area of the X axis, wherein the coordinate (X0, Z0) represents the coordinate of the target parking position;
• (2) a distance D is substantially equal to or greater than a minimum turning radius Rmin of the vehicle, where the distance D represents the distance between a guiding center of a minimum turning operation of the vehicle at the original point (0, 0) and a coordinate (X1, Z1), and the coordinate (X1, Z1) represents a turning end point of an expected arched path of movement of the vehicle during parking;
• and (3) a vehicle angle φ generated in response to turning movement of the vehicle at the minimum turning radius Rmin is substantially equal to or greater than the parking angle (θ).

• and
• judging means for judging that the vehicle can be parked at the target parking position based upon satisfaction of the condition (2Rmin−X0)2+Z02≧(2Rmin)2, where Rmin is a minimum turning radius of the vehicle and X0, Z0 are coordinates of the target parking position.
