Solution Overview
Problem
Existing wireless charging technologies for autonomous driving vehicles face challenges in efficiently charging vehicles while driving, as they need to consider factors such as transmitter specifications, driving speed, and location.
Innovation Solution
A vehicle system that includes a wireless power receiver, a transceiver for communication with the wireless power transmitter, and a controller that manages the wireless charging process. The controller determines whether wireless charging is needed based on the battery state and driving route, searches for an optimal driving speed for efficient charging, and performs wireless charging at that speed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless charging is performed while the vehicle is driving, then charging convenience is improved, but charging efficiency deteriorates due to variable driving speed and location
Solution Approach 1:
The system dynamically adjusts the driving speed to optimize wireless charging efficiency. The controller receives information about transmitter specifications and determines an optimal driving speed that maximizes power reception while maintaining charging convenience during motion.
Solution Approach 2:
The system changes the driving speed parameter based on transmitter specifications and charging requirements. By adjusting the vehicle's speed to match optimal charging conditions, the system resolves the contradiction between maintaining motion (convenience) and achieving efficient power transfer.
2Adaptability or versatility
If the vehicle detours to reach a wireless charging road, then charging availability is improved, but loss of time increases
Solution Approach 1:
The system performs preliminary routing calculations to identify wireless charging roads and determine optimal detour paths before the vehicle reaches decision points. By pre-planning routes that incorporate charging opportunities, the system minimizes time loss while maximizing charging availability.
