Highway Lane Guidance Controller with DAS Sensor Correction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current driving lane guidance systems for vehicles on highways lack continuous correction capabilities based on driver assistant system (DAS) sensor information and navigation data, which can lead to reduced reliability and stability during lane changes, especially when interacting with neighboring vehicles.
Innovation Solution
A driving lane guidance system that includes a navigation information receiver, DAS sensors, a controller, and a display unit, which continuously corrects the driving lane by determining the lane change and neighboring vehicle states using forward and surrounding sensor data, and outputs the corrected lane information to peripheral control devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a highway driving assist system uses basic navigation information to determine driving lane, then the system structure remains simple, but the reliability of lane determination deteriorates due to lack of continuous correction capabilities
Solution Approach 1:
The patent merges navigation information with DAS sensor information to determine and correct driving lane. The controller integrates data from multiple sources (navigation receiver and DAS sensors) to continuously correct the driving lane, improving reliability without requiring completely separate systems.
Solution Approach 2:
The system implements continuous feedback by using DAS sensors to detect actual vehicle position and lane changes, then feeding this information back to the controller to correct the driving lane determination. This closed-loop feedback mechanism maintains high reliability through continuous verification and correction.
2Reliability
If the system continuously corrects driving lane using DAS sensor information and navigation information, then the reliability of lane change improves, but the device complexity increases
Solution Approach 1:
The controller performs multiple functions: it determines driving lane from navigation information, detects lane changes using DAS sensors, identifies neighboring vehicles, and continuously corrects the driving lane. This multi-functionality is achieved within a single control unit, avoiding the need for separate dedicated systems for each function.
Solution Approach 2:
The controller acts as an intermediary that processes and integrates information from both the navigation receiver and DAS sensors. It mediates between these different information sources to produce the corrected driving lane determination, coordinating their inputs without requiring direct complex interactions between the sensor systems themselves.
3Reliability
If the system determines neighboring vehicle states and corrects driving lane dynamically, then the safety during lane change improves, but the processing time and system complexity increase
Solution Approach 1:
The system performs continuous detection and correction operations rather than periodic or discrete actions. The DAS sensors continuously monitor for lane changes and neighboring vehicles, and the controller continuously updates the driving lane determination, ensuring safety without interruption or delays.
Solution Approach 2:
The system detects lane changes and neighboring vehicles proactively before actual lane change maneuvers are executed. By continuously monitoring and predicting potential lane changes based on vehicle state and sensor data, the system prepares correction information in advance, reducing processing time during actual lane change events.
