Driver Intention Lane Assistant System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lane assistant systems for autonomous driving vehicles fail to accurately determine a driver's intention when drifting out of a lane, leading to potential uncomfortable or unsafe situations by incorrectly interpreting the driver's actions.
Innovation Solution
A lane assistant system that captures and analyzes user actions and the driving environment to determine the driver's intention, allowing the vehicle to change lanes intentionally or providing warnings and corrections to stay within the lane based on sensor data and route information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the lane assistant system automatically corrects the vehicle moving direction based on lane markings, then the vehicle can maintain lane position, but it may cause uncomfortable or unsafe situations when the driver intends to change lane
Solution Approach 1:
The system continuously monitors driver actions (steering wheel angle, turn signal status) and vehicle state (drifting direction) to dynamically adjust lane assistance. When driver intention to change lane is detected through feedback from multiple sensors, the system suspends automatic correction, allowing the vehicle to follow the driver's intended maneuver while maintaining safety monitoring.
2Measurement precision
If the system monitors multiple user actions and environmental factors to determine driver intention, then the accuracy of intention recognition improves, but the system complexity increases
Solution Approach 1:
The system integrates multiple detection functions into a unified lane assistant system that combines steering angle sensing, turn signal detection, drift direction monitoring, and lane marking recognition. By merging these functions into a single coordinated system with centralized processing, the patent reduces overall system complexity while maintaining high intention recognition accuracy through multi-parameter analysis.

AI summary
In one embodiment, a lane assistant system is configured to provide lane assistance to a driver of an autonomous driving vehicle (ADV) based on the driver's intention determined at the point in time by capturing and analyzing user actions and driving environment surrounding the ADV. By analyzing the user actions and the driving environment surrounding the vehicle, the driver's intention can be determined. The driver's intention can be utilized to interpret whether the driver indeed intends to change lane. Based on the driver's intention, the lane assistance can be provided, either allowing the vehicle change or exit the current lane, or automatically providing warning or correction of the moving direction of the vehicle.
