Assistant apparatus and method for a vehicle in reverse motion
First Claim
1. An assistant apparatus for a vehicle in reverse motion comprising:
- a camera for taking an image rearwardly of a vehicle during a parking operation;
an indication means for showing images from the camera as rearward images;
a vehicle condition detecting means for detecting the vehicle condition;
an estimated locus calculating means for calculating an estimated locus for a vehicle path based on information from the vehicle condition detecting means and the vehicle performance to indicate the estimated locus on the indication means superimposed on the rearward images;
a locus fixing means indicating a first estimated locus in accordance with a steering angle at the initial stage of parking and fixing the first estimated locus at a predetermined condition;
a target locus setting means setting the first estimated locust as a target locus for a vehicle path for parking in a parking space when the first estimated locus is fixed by the locus fixing means; and
a guiding means indicating a second estimated locus varied in accordance with changes of the steering angle during A the parking operation on the indication means, superimposed on the target locus and the rearward images, to guide the second estimated locus to the target locus.

Abstract
A parking assist apparatus which enables even an inexperienced driver to park with no difficulty or anxiety assists the parking operation by taking an image rearwardly of a vehicle during the parking operation by a camera, indicating an estimated locus of the vehicle overlapping with the rearward images on a display, indicating a first estimated locus in accordance with a steering angle of the vehicle at an initial stage of the parking operation on the display, fixing the first estimated locus at a predetermined condition to have the locus as an target locus, indicating the second estimated locus varied in accordance with the change of the steering angle during the parking operation on the display, and guiding the second estimated locus to be in accord with a fixed target locus.

4. An assistant apparatus for a vehicle in reverse motion comprising:
-
a camera for taking a rearward image of the vehicle during the reverse motion, a detecting means for detecting a vehicle condition for reverse motion, a calculating means for calculating an estimated reverse motion locus based on the vehicle condition and vehicle characteristics, and a display showing a latest estimated reverse motion locus as a present locus and one of the estimated reverse motion locus at a specific timing as a target locus for a vehicle path for parking in a parking space, with both the current and the target loci being superimposed onto the rearward image for guiding the current locus to the target locus. - View Dependent Claims (5, 6, 7, 8, 9, 10, 11)

12. An assistant apparatus for a vehicle in reverse motion comprising:
-
a camera for continuously taking a rearward image from the vehicle during the reverse motion, a detecting means for detecting a vehicle condition for reverse motion, a calculating means for calculating an estimated reverse motion locus based on the vehicle condition and vehicle characteristics, and a display showing the estimated reverse motion locus superimposed onto the rearward image, wherein one of the estimated reverse motion locus at a specific timing is fixed as a target locus for a vehicle path for parking in a parking space on the display, and the estimated reverse motion locus is continuously shown on the display while the target locus is shown on the display for guiding the current locus to the target locus even after the target locus is fixed. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)
