Driver-Selectable Electrical Load Control for Vehicle Energy Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle energy management systems primarily focus on energy production loss, neglecting driver convenience by arbitrarily controlling electrical loads, which can degrade fuel efficiency and increase CO2 emissions without considering driver preferences.
Innovation Solution
A driver-friendly electrical load control method and apparatus that allows drivers to select and prioritize electrical loads for energy consumption reduction, using a user interface to manage and control electrical loads through a communication module and control module connected via CAN or hardwire, enabling real-time state information collection and customizable control modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the electrical load is controlled actively to decrease electric energy used for ESA, then fuel efficiency is improved, but driver convenience is degraded
Solution Approach 1:
The system dynamically adjusts electrical load control based on driver selection. The control strategy changes from arbitrary automatic control to driver-selectable modes, allowing the system to adapt between energy efficiency and convenience based on real-time driver preference, thus resolving the contradiction between reducing energy consumption and maintaining driver convenience
Solution Approach 2:
The system incorporates driver feedback through the selection of control modes. By allowing drivers to choose their preferred control level, the system receives continuous feedback about driver convenience requirements, enabling it to adjust control strategies accordingly and avoid degrading driver satisfaction while still managing energy consumption
2Loss of energy
If arbitrary control of electrical loads is implemented, then energy consumption is reduced, but driver satisfaction decreases
Solution Approach 1:
The system enables drivers to self-determine their own control preferences through the user interface. Instead of the system imposing arbitrary control decisions, drivers serve themselves by selecting control modes that match their preferences, ensuring driver satisfaction is maintained while still achieving energy consumption reduction through voluntary participation
3Device complexity
If control of electrical loads is implemented without user interface, then system complexity is reduced, but adaptability to driver preferences is lost
Solution Approach 1:
The control system is segmented into distinct functional modules: a user interface module for receiving driver preferences, a control strategy module for processing selections, and execution modules for implementing control. This segmentation allows the addition of user interaction capabilities without overwhelming system complexity, as each module handles a specific aspect of the control function independently

AI summary
An electrical load control method includes: collecting, by an electrical load control apparatus, state information of one or more electrical loads; receiving, by an output device, the state information of the one or more electrical loads from the electrical load control apparatus; outputting, by the output device, the state information; receiving, by an input device, one or more control objects among the one or more electrical loads and control methods for the one or more control objects; and receiving, by the electrical load control apparatus, a signal corresponding to the received one or more control objects and the received control methods for the one or more control objects from the input device to deliver a signal corresponding to a respective control method for each of the one or more control objects.
