Solution Overview
Problem
Current vehicle control systems separate the use of video images for lateral control and other technologies for longitudinal control, limiting their integration and efficiency.
Innovation Solution
A single camera system that performs both lateral and longitudinal vehicle control by detecting driving lanes and vehicles in real-time, using image processing and vehicle dynamics to maintain a safe distance and lane position, with a human-machine interface for driver confirmation or autonomous operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate systems are used for lateral control (video) and longitudinal control (radar/range finder), then each control function can be optimized independently, but system complexity increases and cost increases
Solution Approach 1:
The patent merges lateral control and longitudinal control functions into a single integrated system that uses video imaging technology for both control dimensions. The controller processes video images to simultaneously determine lateral lane position and longitudinal distance to target vehicles, eliminating the need for separate radar or range finder systems while maintaining optimization of both control functions through unified image processing algorithms
Solution Approach 2:
The video camera system is designed to perform multiple functions: it captures images for both lateral lane keeping control and longitudinal following control. The same imaging device and processing platform serve dual purposes, making the system universal and multi-functional while reducing overall system complexity and component count
2Reliability
If separate systems are used for lateral control (video) and longitudinal control (radar/range finder), then each sensor technology can be optimized for its specific function, but manufacturing cost increases
Solution Approach 1:
The patent combines multiple control functions into a single video-based system, merging what would traditionally require separate video cameras and radar/range finder systems. This consolidation reduces the total number of sensors and processing units needed, thereby lowering manufacturing costs while maintaining optimized performance for both lateral and longitudinal control through sophisticated image processing algorithms
Solution Approach 2:
The imaging system is designed as a universal platform that performs both lateral and longitudinal control tasks. By making the video system multi-functional, the patent eliminates the need to manufacture and integrate separate specialized sensors, reducing overall system cost while preserving the optimized control capabilities through software-based processing
3Ease of manufacture
If separate systems are used for lateral control and longitudinal control, then each system can be independently tested and calibrated, but system integration complexity increases
Solution Approach 1:
The patent merges lateral and longitudinal control into a single integrated video processing system, which consolidates what would otherwise be two separate systems requiring integration. While the processing is unified, the system maintains modularity in its control algorithms, allowing the lateral control module and longitudinal control module to be independently developed, tested, and calibrated before being combined in the final integrated system

AI summary
A system for longitudinal and lateral control of a vehicle. The system includes a camera generating a plurality of images representative of a field of view in front of the vehicle, and a controller receiving the plurality of images. The controller detects an object in the plurality of images, extracts a plurality of features from the plurality of images, generates a reference feature depiction based on the plurality of features from one or more of the plurality of images, generates a comparison feature depiction based on the plurality of features from one of the plurality of images, compares the reference feature depiction and the comparison feature depiction, and determines a longitudinal position of the vehicle relative to the object based on differences between the reference feature depiction and the comparison feature depiction.
