Parking guidance method for vehicle
First Claim
1. A parking guidance method for a vehicle comprising:
- calculating an estimated backward track of the vehicle from a current steering angle detected by a steering angle sensor;
calculating an estimated parking space from the estimated backward track and a relative angle inputted by a driver through an input means;
converting coordinates of the calculated estimated backward track and estimated parking space into image coordinates;
synthesizing the converted image coordinates with an image acquired by a camera provided at the rear of the vehicle; and
displaying the synthesized image on a monitor of the vehicle,wherein the relative angle is an angle formed by a longitudinal axis of the vehicle which stops to park and a longitudinal axis of the vehicle which is placed in the estimated parking space,wherein as the driver adjusts the relative angle by the driver operating the input means the estimated parking space is rotationally moved so as to fit the estimated backward track with respect to the current steering angle and the estimated parking space after the rotational movement is further displayed on the monitor, andwherein when the driver adjusts a steering wheel angle by operation of the steering wheel the estimated parking space is moved in parallel so as to fit an estimated backward track with respect to an adjusted steering angle and the estimated parking space after the parallel movement is further displayed on the monitor.

Abstract
The present invention provides parking guidance methods for a vehicle, which comprises: calculating an estimated backward track of the vehicle from a current steering angle detected by a steering angle sensor; calculating an estimated parking space from the estimated backward track and a relative angle inputted by a driver through an input means; converting coordinates of the calculated estimated backward track and estimated parking space into image coordinates; synthesizing the converted image coordinates with an image acquired by a camera provided at the rear of the vehicle; and displaying the synthesized image on a monitor of the vehicle. The methods enhances driver'"'"'s convenience and safety in the event of back-in perpendicular parking.

18. A parking guidance method for a vehicle comprising:
-
calculating an estimated backward track of the vehicle from a current steering angle detected by a steering angle sensor; calculating an estimated parking space from the estimated backward track and a relative angle inputted by a driver through an input means; converting coordinates of the calculated estimated backward track and estimated parking space into image coordinates; synthesizing the converted image coordinates with an image acquired by a camera provided at the rear of the vehicle; and displaying the synthesized image on a monitor of the vehicle, wherein the relative angle is an angle formed by (i) a reference line which at a stop position before moving, connects a point, the first point a rotating center point of the vehicle as it is moved backward based on the angle of the steering wheel, to a current vehicle position and (ii) a straight line which at a position generated as a result of the backward movements, and wherein when the driver adjusts a steering wheel angle by operation of the steering wheel, the estimated parking space is moved in parallel so as to fit the estimated backward track with respect to an adjusted steering angle and the estimated parking space after the parallel movement is further displayed on the monitor.
