Vehicular Information Provision System for Circular Bus Advertisement Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing advertisement distribution systems for buses, which rely on satellite-positioning and acceleration sensors, are not cost-effective for circular buses as they require a highly functional on-board unit capable of displaying map images and selecting advertisements based on positional and time information, leading to increased costs.
Innovation Solution
A vehicular information provision system that includes a server associating output data with event identification information, an on-board unit specifying vehicle position using satellite-positioning and map information, and an information provision apparatus acquiring and outputting data from the server, with features like congestion determination and priority-based output control to reduce processing load and update information efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a highly functional on-board unit is mounted to enable advertisement selection based on positional and time information, then advertisement distribution capability is improved, but device complexity and cost increase
Solution Approach 1:
The patent extracts the complex advertisement selection and map display functions from the on-board unit and relocates them to an external server. The on-board unit retains only essential functions (position specification, time acquisition, and simple output), while the server handles advertisement data management, map image generation, and selection logic based on positional and temporal information.
Solution Approach 2:
The patent introduces an external server as an intermediary between the simple on-board unit and the advertisement distribution system. The server acts as a mediator that receives position and time data from the on-board unit, processes advertisement selection, generates map images, and returns appropriate advertisement data, thereby enabling complex functionality without complicating the on-board unit.
2Ease of manufacture
If a simple on-board unit is mounted in circular buses, then cost is reduced, but the ability to display map images and select advertisements based on position is lost
Solution Approach 1:
The patent creates a universal system where a simple on-board unit can be deployed across multiple circular buses at low cost, while the external server provides multi-functional capabilities including advertisement selection, map image generation, and position-based routing for different buses. The server adapts to serve multiple clients with diverse requirements without requiring each on-board unit to be complex.
3Loss of information
If advertisement data is updated frequently from a server, then information freshness is improved, but processing load and communication requirements increase
Solution Approach 1:
The patent implements preliminary action by having the server generate and store pre-processed advertisement data and map images in advance, organized by position and time parameters. When the on-board unit requests data based on current position and time, the server can quickly retrieve and return pre-prepared information without performing complex real-time processing, thereby reducing both processing load and communication overhead.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system reduces the processing load on the on-board unit, allows rapid updates, and provides cost-effective information provision by using a simple on-board unit, enabling efficient output of relevant advertisements and alerts to both drivers and passengers.
Implementation Method 1
specify a vehicle position based on positioning information acquired by a satellite-positioning system

AI summary
A vehicular information provision system for providing information to at least one of the inside and outside of a traveling vehicle includes a server configured to associate output data outputted from the vehicle with event identification information for identifying a predetermined event depending on a position on a map and hold the associated output data and event identification information, an on-board unit which is to be mounted on the vehicle and configured to specify a vehicle position based on positioning information acquired by a satellite-positioning system and pre-acquired map information and output the event identification information correlating with the specified vehicle position, and an information provision apparatus which is to be mounted on the vehicle and configured to acquire the output data correlating with the event identification information acquired from the on-board unit from the server and cause the output data to be outputted from an output unit.
