Throttle Signal Bypass for Faster Vehicle Acceleration 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 control system that includes a control module, wiring harness, and signal adjuster, allowing direct communication between the throttle pedal and throttle body, bypassing the electronic control unit, and enabling manual adjustment of throttle responsiveness through a rheostat and control dial.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If the electronic control unit processes throttle signals, then the vehicle automation and control precision are improved, but the throttle responsiveness and driver control are reduced
Solution Approach 1:
The system segments the throttle control signal path into two independent channels: a direct signal path from the throttle pedal to the throttle body that bypasses the ECU, and a separate diagnostic/monitoring path that connects to the ECU. This segmentation allows the primary control function to respond immediately to driver input while the ECU retains ability to monitor and diagnose the system.
Solution Approach 2:
The patent introduces an intermediary device (such as a relay or signal router) that mediates between the throttle pedal and the throttle body. This intermediary creates a direct signal transmission path that does not require ECU processing, thereby improving response speed while still allowing the ECU to receive copies of throttle position data for monitoring purposes.
2Reliability
If the electronic control unit delays acceleration, then the vehicle stability and safety are improved, but the driver control and acceleration performance are reduced
Solution Approach 1:
The control system is segmented into an autonomous direct-control channel that responds immediately to driver input without ECU delay, and a separate ECU monitoring channel that can detect abnormal conditions. This allows normal acceleration to proceed with full driver control while maintaining safety through independent monitoring.
Solution Approach 2:
The throttle control system provides self-service by directly executing driver commands without requiring ECU authorization or processing delays. The system serves itself by having the throttle pedal signal directly actuate the throttle body, eliminating the need for ECU-mediated decision-making in normal operating conditions.
Data Source
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.
