Throttle Control Module Stabilizing Valve Position
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle control systems face challenges in accurately and reliably controlling the throttle valve position, particularly in scenarios where primary and redundant control signals differ, leading to potential unexpected torque increases due to calculation imprecision or service input signals.
Innovation Solution
A throttle control module comprising a primary throttle position module, a redundant throttle position module, and a remedial action module, which transforms desired throttle area signals into corresponding throttle position signals and generates a remedial action signal when differences exceed a predetermined percentage, ensuring the throttle valve is actuated to a stable position, such as high-idle, to prevent torque fluctuations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If primary and redundant throttle position modules are used to improve reliability, then system reliability is improved, but device complexity increases
Solution Approach 1:
The throttle control system is divided into separate functional modules: a primary throttle position module, a redundant throttle position module, and a remedial action module. Each module independently processes throttle position signals, allowing the system to maintain reliability through modular redundancy while managing complexity through functional separation.
Solution Approach 2:
Different modules perform specific localized functions within the overall control system. The primary module handles normal operation, the redundant module provides backup capability, and the remedial action module handles error conditions. This localization of functions allows each component to be optimized for its specific purpose while contributing to overall system reliability.
2Stability of the object's composition
If remedial action is taken when throttle position signals differ to prevent torque fluctuations, then torque stability is improved, but response time increases
Solution Approach 1:
The system continuously monitors and compares primary and redundant throttle position signals in advance, preparing remedial actions before actual discrepancies cause torque fluctuations. This preliminary detection and preparation allows the system to respond proactively to potential issues rather than reactively to actual problems, minimizing overall response time.
Solution Approach 2:
The remedial action module receives feedback from the comparison of primary and redundant throttle position signals and adjusts throttle operation accordingly. This closed-loop feedback mechanism ensures that torque stability is maintained by continuously adapting throttle position based on signal consistency, while the feedback itself is optimized to minimize delays in correction.

AI summary
A throttle control module comprises a primary throttle position module, a redundant throttle position module, and a remedial action module. The primary throttle position module transforms a primary throttle area signal indicating desired throttle area into a primary throttle position signal indicating a first desired throttle position of a throttle valve. The throttle valve is actuated based upon the primary throttle position signal. The redundant throttle position module transforms a redundant throttle area signal indicating desired throttle area into a redundant throttle position signal indicating a second desired throttle position of the throttle valve. The remedial action module selectively generates a remedial action signal based upon a comparison of the first and second desired throttle positions.
