Throttle Signal Bypass Control for Faster Vehicle Acceleration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic throttle control (ETC) systems often override driver decisions, leading to undesirable power lag or flat spots in acceleration curves, limiting driver control over vehicle performance.
Innovation Solution
A throttle control system that processes input signals from the throttle pedal and sends modified signals directly to the throttle body, bypassing the electronic control unit, using a control module, wiring harness, and a signal adjuster with a rheostat for manual adjustment, enhancing throttle responsiveness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the electronic control unit processes throttle signals, then the vehicle acceleration is delayed to prevent abrupt changes, but the throttle responsiveness is reduced causing power lag
Solution Approach 1:
The system segments the throttle control signal processing into two independent paths: the original ECU path that maintains reliability through delay, and the new control module path that provides direct responsiveness. The control module receives pedal position signals and sends throttle control signals independently of the ECU, allowing drivers to choose between delayed (reliable) acceleration and immediate (responsive) acceleration by adjusting the rheostat.
Solution Approach 2:
The control module acts as an intermediary device between the accelerator pedal and the throttle body. It receives signals from the pedal position sensor and directly controls the throttle body through a dedicated wiring harness, bypassing the ECU's delayed processing. The rheostat serves as an adjustable intermediary that allows drivers to blend between the direct control path and the ECU-controlled path.
2Reliability
If the electronic control unit overrides driver decisions, then vehicle performance is protected from abrupt changes, but driver control is reduced
Solution Approach 1:
The system dynamically allows drivers to switch between two control modes: ECU-controlled delayed acceleration (for protected vehicle performance) and direct control module acceleration (for immediate driver response). The rheostat provides continuous adjustability, allowing drivers to blend between these modes based on their immediate needs, making the system adaptable to different driving situations and driver preferences.

AI summary
A throttle control system and methods are disclosed that provide a driver of a vehicle with greater control over engine functions and vehicle performance. The throttle control system 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 control system includes a control module, 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. A control dial coupled with the rheostat facilitates hand operation of the rheostat.
