Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle drive assistance systems struggle to accurately estimate the relationship between driving workload and driving skill, leading to inadequate drive assistance.
Innovation Solution
A vehicle drive assistance system that includes a control unit with a balance determining module to assess the balance state between the required driving ability and the current driving ability based on physical quantities related to the driving operation, such as the difference between a reference traveling route and the actual traveling route, and adjusts drive assistance accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If drive assistance is increased based on estimated driving skill and workload, then driver support is improved, but estimation accuracy of driving skill and workload deteriorates
Solution Approach 1:
The system continuously monitors the difference between reference traveling route and actual traveling route, using this feedback to dynamically adjust drive assistance levels. The balance determining module processes this feedback to assess whether the current drive assistance is appropriate, creating a closed-loop control system that improves estimation accuracy over time.
Solution Approach 2:
The patent replaces subjective estimation of driving skill with objective measurement of physical quantities. Instead of relying on expert judgment or surveys, the system uses sensors to measure actual driving behavior (steering angle, acceleration, route deviation) and automatically determines drive assistance needs based on these measurable parameters.
2Ease of operation
If drive assistance is provided without accurate balance determination, then driver support is maintained, but travel safety deteriorates
Solution Approach 1:
The system continuously monitors the difference between reference traveling route and actual traveling route, using this feedback to dynamically adjust drive assistance levels. The balance determining module processes this feedback to assess whether the current drive assistance is appropriate, creating a closed-loop control system that improves estimation accuracy over time.
Solution Approach 2:
The system proactively determines the balance state between required and current driving ability before safety issues arise. By continuously monitoring physical quantities and predicting when drive assistance levels need adjustment, the system prevents safety problems rather than reacting to them after they occur.
3Measurement precision
If physical quantities related to driving operation are monitored, then balance state determination accuracy is improved, but system complexity increases
Solution Approach 1:
The system uses existing vehicle sensors (steering angle sensor, acceleration sensor, position sensor) that serve multiple functions. These sensors are already part of the vehicle's standard instrumentation for other purposes, so utilizing them for balance determination does not significantly increase system complexity while still providing accurate measurements.
Solution Approach 2:
The balance determining module acts as an intermediary that processes physical quantity data from existing sensors and translates it into drive assistance control decisions. This modular approach allows the system to leverage existing sensor infrastructure without requiring complex new measurement systems.
