Circuit Mode Vehicle Limit Control for Performance and Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ordinary drivers have limited opportunities to engage in vehicle racing due to legal restrictions and safety concerns on public roads, and existing solutions do not adequately provide a controlled environment for them to experience high-speed driving and improve their understanding of vehicles and circuits.
Innovation Solution
A control method for vehicles that determines whether the vehicle is in a circuit mode and assesses the need for safe travel, releasing system limits to enhance performance when safe travel is unnecessary, allowing drivers to experience circuit travel with differentiated control and strategy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If system limits are released to enhance vehicle performance in circuit mode, then acceleration, braking, and turning performance are improved, but safety risks increase
Solution Approach 1:
The patent applies dynamics by making the system limit state adjustable based on driving conditions. The controller dynamically switches between limit release control (for performance) and limit maintenance control (for safety) based on whether the vehicle is in circuit mode and whether safe travel is required. This resolves the contradiction by making the system flexible rather than fixed, allowing performance enhancement when safe and maintaining safety when needed.
Solution Approach 2:
The patent changes the system parameter (limit state) based on driving mode and safety requirements. When circuit mode is activated and safe travel is not required, the controller releases system limits to improve performance. When safe travel is required, the controller maintains limits to ensure safety. This parameter change approach resolves the contradiction by adapting the system state to different operational contexts.
2Ease of operation
If vehicle systems are optimized for circuit mode performance, then driving experience and understanding of vehicles improve, but control complexity increases
Solution Approach 1:
The patent applies self-service by enabling the system to automatically determine whether it is in circuit mode and whether safe travel is required, then autonomously switch between limit release and limit maintenance controls. This eliminates the need for manual driver intervention or complex manual controls, improving driving experience while managing control complexity through automated decision-making.
Solution Approach 2:
The patent makes the control system multi-functional by integrating circuit mode detection, safety requirement assessment, and system limit control into a single unified system. The controller performs multiple functions (detecting circuit mode, evaluating safety needs, adjusting system limits) rather than requiring separate systems for each function, thereby improving driving experience without proportionally increasing control complexity.

AI summary
A method of controlling system limit of a vehicle performing a circuit mode includes determining, by a controller, whether the vehicle arrives at a circuit and enters the circuit mode. The method also includes determining, by the controller, whether safe travel is required based on racing situation information in the circuit upon determining that the vehicle enters the circuit mode. The method additionally includes performing, by the controller, system limit release control for releasing a limit state of a vehicle system for vehicle driving upon determining that safe travel is unnecessary. The disclosed method may limit a vehicle system interlocked with a circuit mode in a vehicle capable of performing a circuit mode in which a general driver may travel on and experience a circuit using a vehicle of the driver.
