Throttle Intake Control Module for Faster Pedal Response
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic throttle control (ETC) systems often override driver decisions, resulting in delayed acceleration and perceived power lag or 'flat spots' in the acceleration curve.
Innovation Solution
A throttle-controlled intake system that includes a control module coupled with an aircharger air intake, processing input signals from the throttle pedal and sending modified throttle position signals to the throttle body, thereby increasing throttle responsiveness and bypassing the electronic control unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the electronic control unit (ECU) processes throttle signals through calculations based on multiple sensor data, then the system provides comprehensive control and monitoring, but the throttle responsiveness is reduced and driver decisions are overruled
Solution Approach 1:
The system segments the throttle control function into two independent pathways: a direct signal pathway from the accelerator pedal to the throttle body that bypasses the ECU, and a separate ECU monitoring pathway that maintains diagnostic and safety functions. This segmentation allows the direct pathway to provide immediate throttle responsiveness while the ECU continues to provide comprehensive control and monitoring through its own calculations and sensor data processing.
2Manufacturing precision
If the ECU uses closed-loop control algorithms to determine throttle positions, then the system achieves precise throttle positioning, but the acceleration response is delayed and power lag occurs
Solution Approach 1:
The system implements preliminary action by establishing a direct signal pathway that immediately transmits accelerator pedal position signals to the throttle body without waiting for ECU processing. This preliminary direct action ensures immediate acceleration response, while the ECU's closed-loop control algorithm operates in parallel to maintain precise throttle positioning through its own feedback mechanisms and calculations.
3Adaptability or versatility
If the ECU centrally controls all throttle functions, then the system maintains unified control logic, but the driver loses direct control and experiences flat spots in acceleration
Solution Approach 1:
The system introduces an intermediary direct signal pathway that acts as a mediator between the accelerator pedal and throttle body, allowing driver input to directly influence throttle operation. This intermediary pathway preserves driver control and eliminates flat spots in acceleration, while the ECU maintains unified control logic through its separate monitoring and diagnostic functions, ensuring system-wide coordination.
Data Source
AI summary
A throttle-controlled intake system is disclosed that provides a driver of a vehicle with greater control over engine functions and vehicle performance. The throttle-controlled intake system includes a control module that is coupled with an aircharger air intake. The control module processes input signals from a throttle pedal of the vehicle and sends modified throttle position signals to a throttle body of the vehicle so as to increase throttle responsiveness of the vehicle. The throttle-controlled intake system further includes a wiring harness and a signal adjuster. The wiring harness electrically couples the control module with the throttle pedal and the throttle body. The control module sends signals directly to the throttle body of the engine, bypassing an electronic control unit of the vehicle. The signal adjuster includes a rheostat that enables manual adjustment of the throttle responsiveness of the vehicle.
