Vehicle Ad Display Control for Power-Aware Cruising Range
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicular advertisement display systems do not consider power consumption, which limits the cruising distance of vehicles displaying advertisements on their outer surfaces.
Innovation Solution
A processor-controlled vehicular advertisement display device that reduces power consumption based on vehicle state, including speed, fuel level, and destination distance, by temporarily stopping or reducing the luminance of advertisement displays on outer surface units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If advertisement information is displayed continuously on the display unit, then the advertisement effect is improved, but the power consumption increases and cruising distance decreases
Solution Approach 1:
The patent applies dynamics by making the advertisement display state changeable based on vehicle conditions. The display unit transitions between displaying advertisement information and not displaying it, depending on vehicle speed and remaining distance to destination. This dynamic adjustment resolves the contradiction by optimizing the balance between advertisement effect and power consumption according to real-time vehicle state.
Solution Approach 2:
The patent changes the display parameter (whether to display advertisement information) based on vehicle speed and remaining distance parameters. When vehicle speed exceeds a threshold or remaining distance is insufficient, the display parameter is changed to stop advertising, thereby reducing power consumption while maintaining advertisement effectiveness under suitable conditions.
2Illumination intensity
If advertisement information is displayed at high vehicle speed, then the advertisement visibility is improved, but the power consumption increases unnecessarily
Solution Approach 1:
The patent changes the display parameter based on vehicle speed parameter. When vehicle speed exceeds a predetermined threshold, the system determines that advertisement visibility is insufficient due to high speed motion, and consequently stops displaying advertisement information to avoid unnecessary power consumption while maintaining adequate advertisement effect.
3Duration of action of moving object
If advertisement information is displayed when distance to destination is long, then the advertisement exposure time is improved, but the power consumption reduces the cruising distance
Solution Approach 1:
The patent changes the display parameter based on the remaining distance parameter to destination. When the remaining distance is greater than a predetermined distance, the system stops displaying advertisement information to conserve power and ensure the vehicle can reach its destination, thereby balancing advertisement exposure time with cruising distance requirements.

AI summary
The vehicular advertisement display device includes a processor. The processor is configured to display advertisement information on a display unit provided on an outer surface of the vehicle main body. The processor is also configured to reduce power consumption of the vehicle based on the vehicle state.
