Portable VRU Class Switching for E-Bike Power Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems for lightweight vehicles, such as e-bikes, struggle to efficiently switch between pedestrian and vehicle modes, leading to inefficient power usage and limited functionality in different operational scenarios.
Innovation Solution
A method and apparatus that determine the coupling state with a vehicle-side control unit to switch between VRU classes, enabling power-saving modes and enhanced communication capabilities based on the coupling status, allowing for efficient power management and maneuver coordination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the apparatus continuously transmits status information and maintains full communication capabilities, then road safety and maneuver coordination are improved, but power consumption increases
Solution Approach 1:
The apparatus dynamically switches between two VRU classes (first VRU class for pedestrian mode, second VRU class for vehicle mode) based on coupling state with the lightweight vehicle. This dynamic classification allows the communication capabilities and power consumption to adapt to the actual operational mode, enabling full vehicle-to-vehicle communication when coupled and basic pedestrian communication when uncoupled.
2Adaptability or versatility
If the apparatus switches between different VRU classes, then adaptability to different operational scenarios is improved, but device complexity increases
Solution Approach 1:
The apparatus changes its VRU class parameter based on the coupling state with the lightweight vehicle. By modifying this classification parameter, the system adapts its communication behavior, transmission capabilities, and power management strategies to match the current operational scenario, whether the user is riding the vehicle or walking independently.
