Autonomous Vehicle Lane Position Planning with Dual Control Logic
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle control systems for autonomous vehicles often fail to accurately designate appropriate lateral lane driving positions, leading to potential collisions and user anxiety, especially when service providers lack knowledge and experience in vehicle control.
Innovation Solution
A vehicle control system that integrates a first control device from the service provider and a second control device from the automaker, where the second device generates a target driving plan based on the first plan and sensor information to ensure accurate lateral lane driving positions and speeds, reflecting automaker knowledge for improved control accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If service providers use their own programs to generate driving plans, then service-specific driving requirements can be met, but control accuracy and safety deteriorate due to lack of vehicle control expertise
Solution Approach 1:
The patent introduces a collaboration mechanism where service providers' driving plan generation programs communicate with automaker-provided vehicle control programs. The automaker's program acts as an intermediary that receives service-specific requirements and translates them into accurate control commands based on professional vehicle control algorithms, thus maintaining both customization and accuracy.
Solution Approach 2:
The patent merges two previously separate systems: service providers' driving plan generation capabilities and automakers' vehicle control expertise. By combining these systems into a cooperative architecture, the patent enables service-specific customization while leveraging professional vehicle control algorithms to maintain high accuracy in lateral lane positioning.
2Device complexity
If autonomous vehicles use basic route designation, then system complexity is reduced, but service quality deteriorates due to inability to control lateral lane positions
Solution Approach 1:
The patent segments the autonomous vehicle control system into two functional modules: driving plan generation (service-specific requirements) and vehicle control execution (professional algorithms). This segmentation allows basic route designation to handle high-level planning while a specialized control module handles detailed lateral positioning, thus maintaining simplicity at the service level while achieving high service quality through dedicated control functions.
3Power
If calculation accuracy for obstacle avoidance is low, then computational requirements are reduced, but safety deteriorates due to inability to control lateral lane positions
Solution Approach 1:
The patent introduces a professional vehicle control program as an intermediary between service providers' driving plans and actual vehicle control. This intermediary contains pre-optimized algorithms for obstacle avoidance and lateral positioning that achieve high safety standards without requiring service providers to implement complex computational models from scratch.
