Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a driving model is created based on past driving history, then the driving support can be provided, but the suitability of the selected allowable vehicle state may not accurately reflect the driver's unique driving state in complex environments
Solution Approach 1:
The patent applies dynamics by making the model contribution rate variable rather than fixed. The contribution rate of driving information to the driving model is dynamically adjusted based on road information characteristics (such as curve radius, gradient, and road type). This allows the system to adapt to complex driving environments by weighting driving information appropriately according to the specific road conditions, resolving the contradiction between model accuracy and environmental adaptability.
2Quantity of substance
If driving information from peculiar driving states is included in the driving model, then more comprehensive driving data is available, but the determination of driving support becomes inappropriate
Solution Approach 1:
The patent applies local quality by differentiating the treatment of driving information based on road conditions. Instead of uniformly including all driving information, the system assigns different contribution rates to driving information depending on the local characteristics of the road (e.g., curve radius, gradient, road type). This selective weighting ensures that driving information from peculiar or inappropriate driving states has reduced influence on the driving model, thereby maintaining determination reliability while still incorporating comprehensive driving data where appropriate.
3Device complexity
If the contribution rate of driving information is fixed, then the driving model creation is simple, but the driving model cannot be optimized for different driving environments
Solution Approach 1:
The patent implements dynamics by transitioning from a fixed contribution rate to a variable contribution rate system. The contribution rate of driving information is dynamically determined based on road information characteristics such as curve radius, gradient, and road type. This dynamic adjustment mechanism allows the driving model to be optimized for different driving environments without requiring completely different model structures, balancing complexity and adaptability.
4Ease of manufacture
If driving support is provided based on a standard driving model, then the support system is easy to implement, but the support may not be appropriate for individual driver characteristics
Solution Approach 1:
The patent applies local quality by customizing the driving model contribution rates according to individual driver characteristics and specific road conditions. Instead of using a uniform standard driving model for all drivers, the system adjusts the contribution rate of driving information based on the particular driver's behavior patterns and the local road environment. This approach maintains implementation feasibility while significantly improving the appropriateness of driving support for individual drivers.

AI summary
Provided is a driving model creating apparatus that can create a more desirable driving model for practical use, even when creating the driving model on the basis of driving track records, and a driving support apparatus that can execute a more appropriate driving support based on the driving model. The driving model creating apparatus creates a driving model for indicating the driving state of a vehicle (10). The driving model creating apparatus creates the driving model on the basis of road information that is information related to the driving environment of the vehicle (10), and driving information that is information related to the driving state of the vehicle, which will change as a result of a driver's driving operation. The driving model creating apparatus also makes the contribution ratio of the driving information with respect to the driving model to be created, to be variable in accordance with the road information.
