Throttle Intake Control Module With ECU-Bypass Signal Adjustment
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, limiting driver control over vehicle performance.
Innovation Solution
A throttle-controlled intake system that includes a control module integrated with an aircharger air intake, processing input signals from the throttle pedal and sending modified signals directly to the throttle body, bypassing the electronic control unit, and featuring a wiring harness and signal adjuster for manual adjustment of throttle responsiveness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the electronic control unit (ECU) processes throttle signals through calculations based on multiple sensor data, then the system provides comprehensive engine control and safety monitoring, but the throttle responsiveness is reduced and driver control is limited
Solution Approach 1:
The patent segments the throttle control function from the central ECU by introducing a dedicated throttle control module that receives pedal position signals directly and controls the throttle body independently. This segmentation allows the driver's direct input to be transmitted without ECU intervention, improving responsiveness while the ECU retains monitoring capabilities for safety and emissions.
Solution Approach 2:
The patent introduces a throttle control module as an intermediary device between the accelerator pedal and the throttle body. This intermediary processes the pedal position signal and directly actuates the throttle, serving as a mediator that bypasses the ECU's calculation-based control while maintaining system integration through electrical connections to the ECU for monitoring purposes.
2Speed
If the ECU uses closed-loop control algorithms to determine throttle positions, then the system achieves precise engine management, but acceleration response is delayed and power lag occurs
Solution Approach 1:
The throttle control module is pre-programmed with throttle response maps that correlate accelerator pedal position directly to throttle opening positions. This preliminary preparation of control data allows the system to execute throttle adjustments immediately based on driver input without requiring real-time calculations, achieving rapid acceleration response while maintaining reliable engine control through pre-validated control strategies.
3Ease of operation
If the ECU overrides driver decisions through calculated throttle positions, then the system maintains optimal engine performance, but the driver experiences reduced control and perceived power lag
Solution Approach 1:
The patent inverts the traditional control architecture by placing the throttle control function in a dedicated module that responds directly to driver input rather than having the ECU impose calculated positions on the throttle. This inversion prioritizes driver intent and direct response, allowing the driver to maintain control while the system achieves improved acceleration performance.

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.
