Custom Drift Control Using Driver Skill and Road Surface Input
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle control systems fail to account for a driver's skill level and road conditions during drifting, leading to unsatisfactory drifting experiences for both experienced and beginner drivers.
Innovation Solution
A custom drift control method and device that differentially performs drifting based on driver input, including accelerator reaction speed, attitude control assist level, and road surface information, allowing drivers to select their preferred level of drifting intensity and assistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional drift control is implemented without considering driver skill level, then drift control function is provided, but experienced drivers feel the control is intrusive while beginner drivers find it difficult to control
Solution Approach 1:
The system dynamically adjusts drift control intervention levels based on real-time detection of driver skill through accelerator reaction speed. The control system transitions from static to dynamic adaptation, modifying control assistance automatically as the driver's skill level is assessed and changes over time
Solution Approach 2:
The system changes key control parameters including attitude control assist level and accelerator reaction speed thresholds based on detected driver skill level. By modifying these parameters according to driver capability, the system resolves the contradiction between providing sufficient control for beginners and avoiding over-control for experienced drivers
2Reliability
If uniform drift control is applied regardless of road conditions, then drift control is simplified, but drifting performance deteriorates on different road surfaces
Solution Approach 1:
The system applies different drift control strategies tailored to specific road conditions detected through sensors. By adjusting control parameters locally according to the actual road surface characteristics (dry, wet, icy, etc.), the system optimizes drifting performance for each condition without requiring a completely different control system
Solution Approach 2:
The drift control system automatically detects road conditions and self-adjusts control parameters without requiring manual intervention from the driver. The system serves itself by autonomously adapting to environmental changes, maintaining reliable drifting performance across varying road surfaces
3Adaptability or versatility
If drift control does not consider accelerator reaction speed, then control system is simpler, but drifting experience is less satisfying for drivers with different reaction speeds
Solution Approach 1:
The system incorporates feedback from accelerator pedal reaction speed to continuously assess driver skill level and adjust drift control accordingly. By measuring the time delay between driver intent and accelerator actuation, the system personalizes the drifting experience while maintaining manageable system complexity through a single key metric

AI summary
A custom drift control method includes: determining whether to enter a drift mode based on a drift mode activation condition; when the drift mode activation condition is satisfied, entering the drift mode; based on the entering the drift mode, receiving input information including at least one of an accelerator reaction speed level, and an attitude control assist level from a user; and based on the input information, performing custom drift control.
