Parking Assist Apparatus with Dynamic Visual Course Marks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional parking assist systems fail to effectively help drivers recognize the longitudinal movement of a vehicle during backing operations, especially when the image displayed is of an asphalt road surface.
Innovation Solution
A parking assist apparatus that includes a camera, a display unit, a movement distance detecting unit, a steering angle detecting unit, and an anticipated-course calculation unit, which superimposes a discontinuous line with marks on the camera image to represent the vehicle's anticipated course, allowing the marks to shift with vehicle movement, and optionally uses different colors or shapes for enhanced visibility.

Engineering Contradiction Analysis
1Device complexity
If only a camera image of asphalt road surface is displayed, then the system is simple, but longitudinal vehicle movement cannot be easily recognized by the driver
Solution Approach 1:
The system introduces an intermediary visual element (the series of marks representing the anticipated course) between the camera image and the driver's perception. These marks serve as a mediator that translates vehicle movement into visible displacement on the display, enabling the driver to recognize longitudinal movement without adding complex hardware

AI summary
A parking assist apparatus characterized by including: a camera (1) for taking an image of a backside of a vehicle; a display unit (6); a movement distance detecting unit (2) for detecting a distance of vehicle movement; a steering angle detecting unit (3) for detecting a steering rudder angle; and an anticipated-course calculation unit (5) for calculating an anticipated course of the vehicle in backing movement according to the steering rudder angle, wherein the parking assist apparatus further includes a display control unit (4) configured to superimpose on the image taken by the camera a discontinuous line including successive marks (PA1, PA2 . . . / PB1, PB2 . . . ) as the anticipated course and display the superimposed image on the display unit (6), and when the vehicle moves the display control unit (4) is configured to shift the marks according to the distance of the vehicle movement.
