Vehicle Power Management Optimizing Energy via Consumer Load Profiles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional driver assistance systems for motor-driven vehicles do not adequately optimize energy consumption by considering secondary consumers' power requirements, leading to suboptimal energy management and increased energy usage.
Innovation Solution
A method that integrates a driving data determination unit and a power management unit to determine driving curve data, taking into account predictive load profile data from secondary consumers, allowing for optimized energy distribution and reduced energy consumption by selecting the most energy-efficient driving curve data sets based on load profiles and energy availability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If driver assistance systems determine driving profiles without considering consumer load profiles, then system complexity is reduced, but energy optimization precision deteriorates
Solution Approach 1:
The patent segments the energy optimization task into two coordinated components: the drive unit control system and the consumer set power management system. Each segment processes its own data (drive parameters and consumer power requirements respectively) and contributes to the overall optimization, maintaining manageable system complexity while achieving precise energy optimization through their integration.
2Speed
If driving curve data is optimized without considering future consumer power requirements, then response time is improved, but total energy efficiency deteriorates
Solution Approach 1:
The system applies preliminary action by having the power management unit pre-determine consumer set power requirements and make this information available to the driving curve data determination before the actual driving decision is made. This allows the drive unit control to anticipate future power needs and optimize its operation accordingly, achieving both rapid response and high energy efficiency.

AI summary
The invention relates to a method for operating a vehicle, which has a drive unit (14), a driving-data determination unit (30), a consumer set (36), and a power management unit (46), which is provided for managing the consumer set (36), wherein: the driving-data determination unit (30) determines driving curve data (FK; FK3) and the drive unit (14) is controlled on the basis of the driving curve data (FK; FK3). The problem addressed by the invention is that of improving the method to the effect that an optimization can be achieved with regard to a defined quality criterion while taking also the consumer set into account. This problem is solved in that the power management unit (46) receives consumer data (VD) from the consumer set (36), the power management unit (46) determines anticipatory load profile data (LD) at least on the basis of the consumer data (VD), determination data (BD) are transmitted to the driving-data determination unit (30) in accordance with the load profile data (LD), the driving-data determination unit (30) determines the driving curve data (FK; FK3) in accordance with the determination data (BD).
