Vehicle Driving Mode Prioritization for Dynamic Safety Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High-performance electric vehicles face critical situations due to the intrinsic separation between dynamic safety systems and driving mode selection, leading to potential failures from overheating or loss of control, as the selected driving mode is fixed and incompatible with system feedback.
Innovation Solution
A driving modes prioritization system integrated into the vehicle, with management and control means that can autonomously recognize and prioritize driving modes based on dynamic parameters, overriding user selections if they pose safety risks, and dynamically adjusting vehicle configurations to maintain safety and performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed driving mode is selected by the user, then the vehicle configuration is stable and easy to control, but the system cannot adapt to changing dynamic conditions leading to safety risks
Solution Approach 1:
The patent implements dynamic driving mode selection where the control system continuously monitors dynamic parameters (acceleration, deceleration, temperature, vehicle speed) and automatically switches between driving modes based on real-time conditions. This resolves the contradiction by making the previously static driving mode selection dynamic and adaptive, ensuring both safety through automatic protection and adaptability through condition-based mode switching.
Solution Approach 2:
The system incorporates feedback mechanisms by continuously monitoring dynamic parameters from sensors and using this information to automatically adjust driving mode selections. The control system receives feedback about battery temperature, motor temperature, acceleration rates, and vehicle speed, then uses this feedback to determine the appropriate driving mode, resolving the contradiction between fixed configuration and adaptive response.
2Device complexity
If the driving mode configuration is kept fixed during operation, then system complexity is reduced, but critical failures can occur due to incompatibility with dynamic system feedback
Solution Approach 1:
The patent introduces dynamic reconfiguration capabilities that allow the control system to adjust driving modes based on real-time dynamic parameters without requiring complex manual intervention. The system automatically adapts configurations for powertrain, suspension, braking, and steering systems based on monitored conditions, resolving the contradiction by implementing automated dynamic adjustment that maintains reliability while managing complexity through intelligent control algorithms.
Solution Approach 2:
The control system performs self-service by automatically monitoring its own operational state and making independent decisions about driving mode selections without requiring continuous user input. The system self-adjusts configurations based on internal sensor data and pre-programmed safety criteria, resolving the contradiction between simplicity and reliability by enabling the system to manage its own complexity through autonomous decision-making.
3Productivity
If dynamic safety systems operate independently from driving mode selection, then system modularity is maintained, but critical situations develop quickly leading to loss of control
Solution Approach 1:
The patent merges the previously separate driving mode selection system with dynamic safety control systems into an integrated control architecture. The control system now simultaneously manages driving mode selections and safety interventions, coordinating powertrain, suspension, braking, and steering systems in unison. This integration resolves the contradiction by eliminating the time delay between independent system operations while maintaining the modular benefits through standardized communication protocols.
Solution Approach 2:
The system performs preliminary actions by proactively adjusting driving modes before critical situations fully develop. By continuously monitoring dynamic parameters and predicting potential safety issues, the control system preemptively modifies vehicle configurations to prevent loss of control scenarios. This resolves the contradiction by providing advance response time while maintaining coordinated control across all vehicle systems.
