User-Defined Drive Mode Automation via Sensor Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle systems lack convenient methods for drivers to change drive modes in response to changing road conditions or desired driving experiences, as current methods require manual intervention and can be distracting or inconvenient.
Innovation Solution
A processor-based system that allows users to define parameters for engaging specific driving modes, automatically activating the selected mode when predefined conditions such as geographic coordinates, speed, or other conditions are met, enabling hands-free and context-aware mode changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual button pressing is used to change drive modes, then the driver can control drive mode changes, but the operation becomes inconvenient and distracting when hands are occupied
Solution Approach 1:
The system automatically detects driving conditions and applies appropriate drive modes without requiring manual driver input. The processor monitors parameters such as speed, steering angle, and brake pedal position to determine when to switch between drive modes, making the system self-serve the driver's needs.
Solution Approach 2:
The patent replaces the mechanical button-pressing system with an electronic automated system. Instead of requiring physical interaction with a button behind the shifter, the system uses electronic sensors and processors to detect driving conditions and automatically engage appropriate drive modes through electronic control of vehicle systems.
2Ease of operation
If automatic drive mode engagement is implemented, then driver distraction is reduced, but the system complexity increases
Solution Approach 1:
The processor-based system serves multiple functions: it monitors various driving conditions (speed, steering angle, brake position), determines appropriate drive modes, and controls multiple vehicle systems (traction, steering, handling, suspension, powertrain, exhaust). This multi-functionality justifies the system complexity by consolidating numerous control tasks into a single integrated system.
Solution Approach 2:
The system continuously monitors driving conditions through sensors that detect parameters such as vehicle speed, steering wheel angle, and brake pedal position. This feedback loop allows the processor to automatically adjust drive modes based on real-time driving conditions, reducing driver distraction while maintaining appropriate vehicle control.
3Adaptability or versatility
If multiple drive modes are available, then driving experience can be customized, but the difficulty of changing modes increases
Solution Approach 1:
The system pre-configures multiple drive modes with specific parameter settings for different driving conditions. Instead of requiring the driver to manually select from multiple modes, the system has drive modes pre-prepared and automatically selects the appropriate one based on detected conditions, making versatility accessible without operational complexity.
Data Source
AI summary
A system includes a processor configured to receive a first set of user-selected parameters, including first user-defined parameter values, the first set defining a condition for engaging a specific user-selected vehicle driving mode. The processor is also configured to receive data indicating current parameter values and automatically engage the user-selected vehicle driving mode responsive to the current parameter values matching first user-defined parameter values.
