Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems for lightweight vehicles, such as e-bikes, lack efficient methods to dynamically switch between pedestrian and vehicle modes based on coupling status with a vehicle-side control unit, leading to inefficient power usage and limited functionality in maneuver coordination.
Innovation Solution
A method and apparatus that determine the coupling state with a vehicle-side control unit to switch between first and second VRU classes, enabling power-saving modes and enhanced functionalities like maneuver coordination by selectively transmitting and receiving data based on the coupling state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the apparatus continuously transmits data in vehicle mode, then maneuver coordination functionality is improved, but power consumption increases
Solution Approach 1:
The apparatus dynamically switches between first and second VRU classes based on coupling state with a lightweight vehicle, allowing transmission behavior and functionality to adapt to current operational conditions. This dynamic classification enables the system to optimize power consumption by activating full vehicle-mode transmission only when coupled with a vehicle, rather than continuously
Solution Approach 2:
The system changes the VRU class parameter based on coupling state, which triggers different transmission behaviors. When coupled with a lightweight vehicle, the apparatus adopts the second VRU class with enhanced transmission capabilities for maneuver coordination. When uncoupled, it switches to the first VRU class with reduced transmission activity, thereby controlling power consumption through parameter adjustment
2Adaptability or versatility
If the apparatus switches between VRU classes based on coupling state, then adaptability is improved, but device complexity increases
Solution Approach 1:
The apparatus uses feedback from the coupling state detection to automatically determine the appropriate VRU class. The system monitors whether it is coupled with a lightweight vehicle and automatically selects the corresponding VRU class (first or second), reducing the need for complex manual control logic while improving adaptability to different operational modes
3Reliability
If the apparatus transmits status information in pedestrian mode, then road safety awareness is improved, but power efficiency deteriorates
Solution Approach 1:
The apparatus applies partial action by transmitting status information selectively based on VRU class. In the first VRU class (pedestrian mode without full vehicle coupling), the transmission of status information is limited or disabled. In the second VRU class (coupled vehicle mode), full transmission capabilities are activated. This partial action approach ensures that power-intensive transmission occurs only when the apparatus has full vehicle integration and control capabilities
