Transmission Driver Profiling for Personalized Shift Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for monitoring and analyzing vehicle condition data do not effectively utilize this information to provide personalized transmission settings for individual drivers, leading to suboptimal shifting characteristics based on their driving styles.
Innovation Solution
A system that gathers transmission data from vehicles with comparable transmissions, creates driver profiles based on shifting behavior, and standardizes vehicles by assigning them to specific profiles, allowing for customized parameterization of the transmission control unit to match individual driving styles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If transmission data is gathered from multiple vehicles to create driver profiles, then personalized transmission settings can be provided, but data processing complexity and time increase
Solution Approach 1:
The patent segments the transmission control system into modular components: a data gathering module that collects transmission data from multiple vehicles, a profile creation module that processes this data to create driver profiles, and a transmission control unit that applies the personalized settings. This segmentation allows each module to handle specific tasks independently, reducing overall system complexity while enabling personalized transmission settings for different driving styles.
2Loss of energy
If transmission parameters are customized for individual driving styles, then fuel efficiency and emissions are improved, but transmission control complexity increases
Solution Approach 1:
The patent implements parameter changes by adjusting transmission control parameters based on detected driving styles. The system monitors driving behavior patterns and modifies transmission parameters such as shift points, shift duration, and torque converter lockup timing to optimize fuel efficiency for each driver's preferred style. This approach reduces energy loss without requiring complete redesign of the transmission control system.
3Reliability
If driver profiles are created based on gathered transmission data, then transmission performance is optimized, but measurement and analysis difficulty increases
Solution Approach 1:
The patent employs feedback mechanisms where the transmission control unit continuously monitors driving behavior and compares it against stored driver profiles. The system provides feedback by adjusting transmission parameters in real-time based on the detected driving style, and this feedback loop allows the system to learn and adapt to each driver's preferences over time, improving transmission performance while simplifying the measurement process through iterative optimization.

AI summary
A method for standardizing a plurality of motor vehicles may include determining a characteristic value of an individual vehicle (50) based on transmission data for the individual vehicle from a data gathering device (6) associated with the individual vehicle. The transmission data for the individual vehicle may be associated with shifting characteristics of a transmission of the individual vehicle for at least one of an operation interval of the individual vehicle or a mileage of the individual vehicle. Additionally, the method may include assigning the individual vehicle to one of a plurality of profiles (10.1, 10.2, 10.3, 10.4, 10.5) of a classification (10) based at least in part on a magnitude of the characteristic value. The classification may be determined based at least in part on average values and a magnitude and frequency of deviations from the average values of transmission data gathered for a plurality of vehicles (5).
