Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing all-terrain adaptive mode for vehicles is inadequate in adapting to different terrains, particularly when driving on urban roads, snow, mud, or sand, as it struggles to optimize engine power output effectively.
Innovation Solution
A vehicle power output control method and system that recognizes the current road surface through image analysis, determines the appropriate terrain mode, and adjusts engine torque using a power output curve based on the accelerator pedal's stepping depth to optimize power output for the terrain.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional all-terrain adaptive mode is used with preset gear settings, then the vehicle can operate on different terrains, but the adaptation to complex road conditions is unsatisfactory and engine power output cannot be optimized effectively
Solution Approach 1:
The patent implements dynamic terrain mode switching based on real-time road surface recognition. Instead of static preset modes, the system continuously captures road surface images, recognizes terrain types, and dynamically adjusts the terrain mode and engine power output accordingly. This dynamic adaptation resolves the contradiction by enabling reliable performance across complex terrains while maintaining versatility.
Solution Approach 2:
The system establishes a feedback loop where road surface images are continuously captured and analyzed, and the recognition results feed back to adjust the terrain mode and power output strategy. This closed-loop control ensures the vehicle adapts reliably to changing road conditions, resolving the performance reliability issue while maintaining adaptability.
2Adaptability or versatility
If multiple preset terrain modes are provided, then the vehicle can handle different terrain types, but the system cannot effectively optimize power output for complicated road conditions
Solution Approach 1:
The patent changes the parameter of power output by selecting different power output curves corresponding to different terrain modes. Based on road surface recognition results, the system adjusts engine output torque parameters in real-time, enabling effective power optimization for complicated road conditions while maintaining comprehensive terrain coverage.
Solution Approach 2:
The system pre-establishes multiple power output curves corresponding to different terrain modes. When a specific terrain is recognized, the appropriate pre-prepared power output curve is immediately selected and applied, enabling rapid power optimization without complex real-time calculations, thus improving productivity while maintaining adaptability.
3Device complexity
If manual terrain mode selection is used, then the system structure remains simple, but the responsiveness to changing road surfaces is delayed and power adaptation is not real-time
Solution Approach 1:
The system implements self-service terrain adaptation through automatic road surface recognition and autonomous terrain mode selection. The vehicle automatically captures road images, recognizes terrain types, and adjusts power output without driver intervention. This maintains relatively simple system structure while achieving real-time response to terrain changes, resolving the contradiction between complexity and response speed.
