Solution Overview
Problem
Existing control units in lightweight vehicles, such as pedal electric cycles and electric kick scooters, require complex processing capabilities and radio interfaces for V2X communication, leading to increased costs and resource inefficiencies.
Innovation Solution
Shift the processing and determination of sensor information and reaction information from the control unit to a personal mobile terminal, reducing the control unit's complexity and eliminating the need for a radio interface, while enabling V2X communication through the mobile terminal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the control unit processes sensor information and handles V2X communication directly, then the vehicle has integrated control capability, but the control unit complexity and cost increase
Solution Approach 1:
The system divides functionality into two segments: the control unit handles vehicle control operations while the personal mobile terminal handles sensor information processing and V2X communication. This segmentation allows each component to be optimized independently, reducing overall system complexity while maintaining integrated control capability.
Solution Approach 2:
The personal mobile terminal acts as an intermediary between the control unit and external communication networks. It receives sensor information from the control unit, processes it, and handles V2X communication, thereby shielding the control unit from communication complexity while maintaining system integration.
2Adaptability or versatility
If the control unit includes radio interface for V2X communication, then direct vehicle-to-everything communication is enabled, but the cost and resource requirements increase
Solution Approach 1:
The personal mobile terminal, being a multi-functional device, is leveraged to handle V2X communication in addition to its primary functions. This eliminates the need for a dedicated radio interface in the control unit while maintaining full V2X communication capability through the mobile terminal's existing communication infrastructure.
Solution Approach 2:
The personal mobile terminal, which the user already possesses and operates, is utilized to provide V2X communication services to the vehicle. This self-service approach eliminates the need for additional dedicated communication hardware in the vehicle, reducing cost and complexity while maintaining communication functionality.
3Speed
If processing power is concentrated in the control unit, then real-time vehicle control is optimized, but the overall system resource utilization decreases
Solution Approach 1:
Processing tasks are segmented between the control unit and personal mobile terminal based on their respective strengths. The control unit focuses on time-critical vehicle control operations requiring real-time response, while the mobile terminal handles less time-critical tasks like sensor data processing and communication protocols, optimizing overall system resource utilization.
Solution Approach 2:
The control unit performs only the essential real-time control processing needed for safe vehicle operation, while delegating additional processing tasks to the mobile terminal. This partial action approach ensures real-time control requirements are met without over-provisioning the control unit's processing capabilities, improving overall system efficiency.
