Vehicle Control Device Dynamic Fuel Conservation Mode
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle fuel conservation modes restrict acceleration, potentially causing inconvenience or increased risk in situations requiring rapid acceleration, such as merging or overtaking, while aiming to enhance fuel efficiency.
Innovation Solution
A vehicle control device that selectively activates or deactivates a fuel conservation mode based on sensed driving information and conditions, such as lane changes, traffic signals, and vehicle proximity, allowing for intelligent management of acceleration to balance fuel efficiency with driving needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the fuel conservation mode is activated to restrict acceleration, then fuel efficiency is improved, but driving convenience and safety are worsened in situations requiring rapid acceleration
Solution Approach 1:
The fuel conservation mode is made dynamically adjustable rather than fixed. The controller can modify the degree of acceleration restriction based on real-time driving conditions, vehicle state, and user preferences, allowing the system to adapt between fuel efficiency and driving performance as needed
Solution Approach 2:
The system changes operational parameters by offering multiple acceleration restriction levels (e.g., different throttle response curves, different maximum acceleration rates). This allows the vehicle to operate in a fuel-conserving manner during normal driving while capable of providing stronger acceleration when conditions warrant it
2Loss of energy
If the fuel conservation mode restricts acceleration, then fuel efficiency is improved, but driving safety is worsened in emergency or merging situations
Solution Approach 1:
The system continuously monitors driving conditions through sensors and user inputs, providing feedback to the controller. When emergency situations are detected (such as rapid steering input, brake release, or user activation of sport mode), the system receives feedback and automatically adjusts or deactivates the acceleration restriction to maintain safety
Solution Approach 2:
The system prepares for potential safety needs by pre-configuring multiple operation modes and being ready to switch between them. The driver can pre-select their preferred balance between fuel efficiency and performance, and the system has preliminary safeguards in place to detect and respond to emergency conditions before they become critical

AI summary
A vehicle control device includes a sensor configured to sense driving information of a vehicle, and a controller. The controller is configured to activate or deactivate a fuel conservation mode of the vehicle based on a user input, and restrict acceleration of an engine of the vehicle to be within a predetermined range based on an accelerator pedal of the vehicle being pressed with a force that is greater than a threshold force and based on the vehicle being in an activated state of the fuel conservation mode. The controller is also configured to, based on the driving information satisfying a first condition, release a restriction on the acceleration of the engine of the vehicle in the activated state of the fuel-conservation mode.
