Vehicle Recuperation Prediction via Speed Profile Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle operation methods do not effectively inform drivers about imminent kinetic energy recuperation, leading to suboptimal braking behavior and energy recovery, as they lack real-time data on speed profiles and braking paths based on varying recuperation intensities and environmental conditions.
Innovation Solution
A method that assesses imminent actuation of the recuperation unit, outputs driving information on probable speed and braking paths through a driver assistance system, considering factors like energy storage state, vehicle mass, tire pressure, road conditions, and traffic regulations, to enhance driver awareness and adjust driving behavior.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the driver is not informed about imminent recuperation actuation, then the driver assistance system remains simple, but energy recovery efficiency deteriorates due to suboptimal braking behavior
Solution Approach 1:
The system provides feedback to the driver about imminent recuperation actuation through the output apparatus, displaying information about speed profiles and braking paths. This feedback loop enables the driver to adjust behavior optimally for energy recovery while maintaining simple system architecture.
2Productivity
If real-time speed profile and braking path information is provided to the driver, then driving behavior optimization improves, but system complexity increases
Solution Approach 1:
The system performs preliminary calculations of speed profiles and braking paths based on prescribable recuperation intensities before the actual recuperation event. This allows the driver to be informed in advance about expected vehicle behavior, enabling optimization of energy recovery without requiring complex real-time control systems.
Solution Approach 2:
The system varies display parameters (speed profiles, braking paths) based on different prescribable recuperation intensities. By changing these informational parameters rather than physical system parameters, the system provides comprehensive information while maintaining simple hardware architecture.
3Reliability
If multiple parameters (speed profile, braking path, recuperation intensity) are displayed to the driver, then driving behavior adjustment improves, but information processing complexity increases
Solution Approach 1:
The information display is segmented into distinct components: first parameters indicating imminent actuation, second parameters showing speed profiles, and third parameters displaying braking paths. This segmentation allows the driver to process information in manageable stages while the system maintains comprehensive control accuracy through systematic parameter organization.

AI summary
A method for controlling operation of a vehicle with a recuperation unit may include determining at least one first parameter denoting possible imminent actuation of the recuperation unit, evaluating whether actuation of the recuperation unit is imminent, and if yes, calculating a probable profile for a speed of the vehicle during the actuation on the basis of a prescribable level of a recuperation intensity of the recuperation unit. The method may also include generating at least one second parameter denoting the ascertained probable profile of the speed of the vehicle during the ascertained imminent actuation of the recuperation unit and displaying the at least one second parameter with an output apparatus.
