Vehicle Drift Control Adapting to Driver Intent
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle body drifting restraining devices interfere with driver operation, worsening steering feel when the driver wishes to operate the vehicle proactively.
Innovation Solution
A vehicle body drifting restraining device that prohibits or performs drifting control based on the state of the brake control device operation prohibition switch and cruise control device, using sensors and control units to determine driver intent and adjust the level of intervention accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If vehicle body drifting restraining control is performed continuously, then vehicle safety is improved, but steering feel deteriorates when driver operates vehicle proactively
Solution Approach 1:
The system dynamically adjusts the level of drifting restraining control based on detected driver intent. When proactive driving is detected, the control is reduced or suspended; when passive driving is detected, normal control is maintained. This dynamic adaptation resolves the contradiction by making the system flexible rather than fixed.
Solution Approach 2:
The system uses feedback from steering torque sensors and other sensors to continuously monitor driver behavior and adjust control intensity accordingly. This closed-loop feedback mechanism allows the system to respond to driver intentions in real-time, preventing interference when proactive driving is detected while maintaining safety when appropriate.
2Stability of the object's composition
If drifting restraining control is activated, then vehicle body stability is improved, but driver's proactive operation is interfered with
Solution Approach 1:
The control system transitions from a static on/off state to a dynamic multi-level state that adapts to driver intentions. The system can operate in different modes (full control, reduced control, suspended control) based on real-time detection of driver proactive behavior, thereby maintaining stability when needed while preserving driver flexibility when desired.
Solution Approach 2:
The system introduces an intermediary detection mechanism (steering torque sensor, control unit) that mediates between the driver's proactive operations and the drifting restraining control. This intermediary detects driver intent and acts as a bridge to appropriately modulate the control intensity, preventing direct interference with proactive driver operations.
3Reliability
If brake control device is always available for drifting restraint, then vehicle safety is improved, but driver's proactive driving intent is restricted
Solution Approach 1:
The availability of brake control for drifting restraint is made dynamic rather than constant. The system automatically adjusts control availability based on detected driver intent, suspending or reducing automated brake intervention when proactive driving is detected, thereby preserving driver control autonomy while maintaining safety when appropriate.
Solution Approach 2:
The system performs self-assessment of driver intent through sensor data and automatically adjusts its own control availability without requiring explicit driver input. This self-service capability allows the system to autonomously determine when to prioritize safety intervention and when to defer to driver autonomy, resolving the contradiction internally.
