Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle control systems lack dynamic control over driving dynamics, limiting precise control and performance, especially in high-performance driving scenarios, due to static distribution of force and traction.
Innovation Solution
A system comprising a user input device and computing system that dynamically controls driving dynamics by altering power output balance between vehicle portions, such as front and rear wheels, and brake bias, allowing real-time manual input to adjust power distribution and braking force proportionately.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If static drivetrain controls are used with preset drive modes, then the system complexity is reduced and ease of operation is improved, but the adaptability and precision of vehicle control in high-performance driving is limited
Solution Approach 1:
The patent implements dynamic control of drivetrain parameters by allowing the driver to continuously adjust power distribution between front and rear wheels, brake bias, and throttle response in real-time during driving operations, transforming static preset modes into dynamically adjustable controls that adapt to immediate driving conditions and driver intent
Solution Approach 2:
The system enables real-time modification of key drivetrain parameters including power output balance, brake force distribution, and throttle response characteristics through driver input devices, allowing continuous parameter adjustment rather than discrete preset selections, thereby enhancing adaptability while maintaining operational simplicity
2Device complexity
If static power distribution in drivetrain is used, then the device complexity is reduced, but the precision control and performance in high-performance driving is limited
Solution Approach 1:
The patent introduces dynamic adjustment capabilities that allow real-time modification of power distribution and braking characteristics during vehicle operation, enabling precise control adaptation to high-performance driving scenarios without requiring overly complex static systems
Solution Approach 2:
The control system integrates multiple functions into a unified drivetrain control architecture that simultaneously manages power distribution, brake bias, and throttle response through coordinated operation of existing drivetrain components, achieving precision control without proportionally increasing device complexity
3Ease of operation
If preset drive modes are implemented, then ease of operation is improved, but the real-time control capability and driving enjoyment are reduced
Solution Approach 1:
The system transitions from static preset modes to dynamic real-time control by enabling continuous adjustment of drivetrain parameters during operation, allowing drivers to modify power distribution, brake bias, and throttle response on-the-fly to match changing driving conditions and maintain optimal performance
