Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems fail to maintain high power transmission efficiency when vehicles deviate from the power feeding lane at night, leading to reduced charging efficiency.
Innovation Solution
A control device that includes a processor to detect reduced power transmission efficiency due to lateral deviation from the power feeding lane and activates an irradiation unit to adjust the light emission range based on steering operations, enhancing power transmission efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the vehicle travels laterally displaced from the power feeding lane at night, then the driver has better visibility and comfort, but the power transmission efficiency is reduced
Solution Approach 1:
The irradiation unit dynamically adjusts its light emission range based on the vehicle's lateral position relative to the power feeding lane. When displacement is detected, the system expands the illumination range to guide the driver back to the optimal charging position, thereby restoring power transmission efficiency while maintaining driver comfort.
Solution Approach 2:
The control device continuously monitors the vehicle's lateral position and provides feedback through adjusted light emission. When the vehicle is displaced, the system increases illumination intensity and range to signal the driver to correct the position, creating a closed-loop control system that maintains optimal power transmission efficiency.
2Loss of energy
If the irradiation unit is activated to guide the vehicle back to the power feeding lane, then the power transmission efficiency is improved, but the energy consumption increases
Solution Approach 1:
The irradiation unit operates at increased intensity only partially - specifically when lateral displacement from the power feeding lane is detected. The system applies excessive illumination action only during the corrective phase, rather than continuously, thereby improving power transmission efficiency when needed while minimizing overall energy consumption.
Solution Approach 2:
The control device changes the operational parameters of the irradiation unit based on detected lateral position. When displacement exceeds a threshold, the system increases light emission intensity and range; when the vehicle is properly aligned, the system reduces or stops irradiation, thus optimizing the balance between power transmission efficiency and energy consumption.

AI summary
A vehicle electronic control unit (ECU) determines whether the power transmission efficiency is decreasing due to the vehicle moving laterally from the power supply lane at night, and if the power transmission efficiency is decreasing, the ECU activates an adaptive front-lighting system (AFS), which can automatically change the range of light emitted in a traveling direction of the vehicle in response to a steering operation.
