Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicular control systems rely on default operating parameters that may not align with the specific usage patterns of individual vehicles, leading to suboptimal performance and fuel efficiency, requiring manual adjustments by technicians and failing to account for actual operational characteristics.
Innovation Solution
A system that determines a vehicle's duty cycle based on operation data, compares it to a population of duty cycles, identifies a desired cycle, and selectively adjusts electronic control parameters to match the identified cycle, allowing for automatic optimization of operating parameters such as fuel consumption and performance without manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If default operating parameters are used in vehicular control systems, then the system is simple and easy to implement, but the fuel efficiency and performance are suboptimal
Solution Approach 1:
The control system automatically determines the vehicle's duty cycle based on operation data, compares it to a population of duty cycles, and selectively adjusts electronic control parameters without requiring manual intervention by technicians. This self-service approach optimizes fuel efficiency while managing system complexity through automated processes.
Solution Approach 2:
The system changes electronic control parameters (trim parameters) based on the determined duty cycle to optimize vehicle performance and fuel efficiency. By dynamically adjusting parameters such as fuel injection timing, ignition timing, and other operating parameters, the system achieves better fuel economy without requiring a complete redesign of the control system architecture.
2Productivity
If manual adjustments of operating parameters are required, then the system can be optimized for specific usage patterns, but the ease of operation decreases and requires technician intervention
Solution Approach 1:
The system performs automatic duty cycle determination and parameter adjustment without requiring technician intervention. The control system independently analyzes operation data, determines the vehicle's duty cycle, and adjusts parameters accordingly, eliminating the need for manual adjustments while maintaining operational optimization.
Solution Approach 2:
The system uses operation data as feedback to continuously monitor and determine the vehicle's actual duty cycle. This feedback mechanism enables the system to automatically adapt to specific usage patterns and adjust parameters in real-time, replacing manual adjustment processes with an automated closed-loop control system.
3Adaptability or versatility
If default operating parameters are used, then the control system is easy to implement, but it fails to account for actual operational characteristics of individual vehicles
Solution Approach 1:
The system changes electronic control parameters based on the determined duty cycle to match actual operational characteristics. By adjusting parameters such as fuel injection timing, ignition timing, and valve timing according to the vehicle's specific usage patterns, the system achieves adaptability without requiring complex hardware modifications.
Solution Approach 2:
The system pre-determines the vehicle's duty cycle by comparing operation data against a population of duty cycles before making parameter adjustments. This preliminary analysis allows the system to proactively adapt to the vehicle's operational characteristics and prepare optimal parameters in advance, rather than requiring complex real-time adjustments.

AI summary
A method includes: receiving, by a controller of a vehicle, operation data indicative of a duty cycle for the vehicle, wherein the duty cycle is a substantially repeatable set of vehicle or vehicle component operations for a particular event or for a predefined time period; identifying, by the controller, a desired vehicle duty cycle from a population of vehicle duty cycles based on the operation data indicative of the duty cycle for the vehicle and on a desired operating parameter of the vehicle; receiving, by the controller, a set of trim parameters that are electronic operational parameters associated with the desired vehicle duty cycle; and controlling, by the controller, one or more operating points of the vehicle based on the set of trim parameters.
