Adaptive Drive Mode System for Off-Road Vehicle Settings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle drive mode systems lack user personalization and adaptability, particularly in off-road conditions, where settings such as throttle mapping, suspension stiffness, and shift points do not automatically adjust to optimize vehicle performance.
Innovation Solution
An adaptive drive mode system that allows users to pre-program a drive mode button and includes sensors and a processor to detect vehicle settings and environmental conditions, modifying vehicle system settings accordingly, such as throttle mapping, suspension stiffness, shift points, and ride height, to tailor the drive mode for specific operations like low-range off-road mode.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If drive mode settings are fixed for specific driving conditions, then vehicle performance is optimized for those conditions, but the system lacks adaptability to different operating environments
Solution Approach 1:
The drive mode system dynamically adapts settings based on detected operating conditions (low-range mode, environmental sensors) rather than using fixed predetermined settings. The processor automatically modifies vehicle system settings based on real-time sensor data, making the system flexible and adaptive to different driving conditions without requiring multiple separate mode selections
Solution Approach 2:
Sensors detect vehicle settings and environmental conditions, providing feedback to the processor which then automatically modifies drive mode parameters. This closed-loop feedback system enables the drive mode to adapt to actual operating conditions, resolving the contradiction between fixed optimization and environmental adaptability
2Adaptability or versatility
If multiple drive modes are provided for different conditions, then vehicle performance is optimized for various situations, but user operation becomes more complex
Solution Approach 1:
The drive mode system automatically detects operating conditions through sensors and self-adjusts vehicle settings without requiring manual mode selection by the user. The processor monitors sensor data and autonomously modifies drive mode parameters, eliminating the need for users to navigate complex mode selection menus while still providing optimized performance for different conditions
3Extent of automation
If drive mode settings are manually adjusted, then user personalization is achieved, but the system lacks automatic adaptation to environmental conditions
Solution Approach 1:
The system pre-programs drive mode buttons with user-selected preferences and automatically applies appropriate settings based on detected conditions. User preferences are stored and automatically retrieved when specific conditions are detected, combining automated environmental adaptation with preserved user personalization choices
Solution Approach 2:
Sensors provide continuous feedback about environmental conditions and vehicle state to the processor, which automatically adjusts drive mode settings while respecting user-preferred configurations. The system learns from sensor feedback and automatically applies user preferences to appropriate conditions, achieving both automation and personalization

AI summary
Systems and methods are provided for applying an adaptive drive mode to a vehicle, including: the vehicle detecting selection of a drive mode and setting vehicle systems to correspond to the selected drive mode to place the vehicle in the selected drive mode; an adaptive drive mode circuit using vehicle sensor data to determine whether the vehicle is in a low-range mode of operation; and modifying the vehicle system settings that correspond to the selected drive mode if the vehicle is in low-range mode to adapt the vehicle system settings that correspond to the selected drive mode for the low-range mode of operation.
