Throttle Valve Control for Simultaneous Gas and Brake Input
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle control units fail to accurately control the throttle valve when both the gas and brake pedals are operated simultaneously, as they do not consider the degree of brake pedal operation, leading to inefficiencies in reducing vehicle drive output.
Innovation Solution
An electronic control unit that continuously monitors and evaluates the positions, depression forces, and operating conditions of both the gas and brake pedals, using sensors and a processor to assess a combined factor of safety, which regulates the throttle valve's operation to effectively manage drive power.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the control unit only considers the degree of accelerator pedal operation to control the throttle valve, then the control system is simple, but the control precision and effectiveness are insufficient
Solution Approach 1:
The control unit merges the monitoring functions of both accelerator pedal and brake pedal into a single integrated control system. By combining the operational data from both pedals, the system achieves more precise throttle valve control without requiring separate independent control mechanisms, thus resolving the contradiction between system simplicity and control precision.
Solution Approach 2:
The control unit dynamically changes the throttle valve control parameters based on the combined operational state of both pedals. By adjusting the throttle closure degree according to the specific combination of accelerator and brake pedal positions, the system achieves precise control adaptability while maintaining a relatively simple control architecture.
2Measurement precision
If the control unit monitors both gas pedal and brake pedal operations, then the control precision improves, but the device complexity increases
Solution Approach 1:
The control unit is designed with multi-functionality to handle both accelerator pedal and brake pedal monitoring within a single device. This universal controller performs multiple functions including detecting both pedal operations, evaluating their combined effect, and controlling the throttle valve accordingly, thereby improving detection precision without proportionally increasing device complexity.
Solution Approach 2:
The control unit utilizes existing vehicle sensors and processing capabilities to monitor both pedals, making the system self-sufficient. By leveraging already-present computational resources and sensor infrastructure, the system achieves enhanced monitoring precision without requiring entirely new dedicated hardware for each pedal.
3Ease of operation
If the throttle valve is closed completely or partially based only on accelerator pedal position, then the response is simple, but the drive power reduction effectiveness is insufficient
Solution Approach 1:
The control system dynamically adjusts the throttle valve closure strategy based on the real-time operational state of both pedals. Rather than using a fixed closure rule, the system adaptively determines the appropriate throttle position by evaluating the combined input from accelerator and brake pedals, thereby achieving effective drive power reduction while maintaining operational simplicity.
Solution Approach 2:
The control unit implements feedback mechanisms that continuously evaluate the operational state of both pedals and adjust the throttle valve accordingly. By incorporating feedback from both accelerator and brake pedal positions, the system achieves reliable drive power reduction effectiveness while maintaining a straightforward control response mechanism.

AI summary
Embodiments of present invention provide an improved and more precise electronic control unit mechanism for a vehicle to effectively control operation of a throttle valve, based on operating conditions of a gas pedal and a brake pedal both, whenever a unintentional or accidental situation of simultaneous operations of the gas pedal and the brake pedal is detected. The electronic control unit regulates the functioning of the throttle valve, based on the positions of the gas pedal and the brake pedal both, and hence controls the output drive power of the vehicle.
