Vehicle Information Server Priority Scheduling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems fail to determine an appropriate transmission schedule for multiple vehicles based on individual vehicle conditions, leading to potential wasteful communication and delayed real-time information transmission.
Innovation Solution
An information provision system that includes a receiver, controller, and transmitter, which sets priorities for information transmission based on the types of information and internal and external conditions of each vehicle, extending communication bandwidth in descending order of priorities to ensure timely delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a transmission schedule is determined using only the conditions of a single vehicle, then the transmission can be simplified, but when pieces of information are requested by in-vehicle devices mounted on multiple vehicles, an appropriate transmission schedule in accordance with the condition of each vehicle cannot be determined
Solution Approach 1:
The patent segments the transmission schedule determination by creating separate scheduling processes for each vehicle based on their individual conditions. The server divides the plurality of vehicles into different groups or handles each vehicle's information requests independently, allowing customized transmission schedules for each vehicle while managing multiple vehicles through systematic segmentation of the scheduling task.
Solution Approach 2:
The transmission schedule is made dynamic by continuously adjusting it based on real-time vehicle conditions such as location, speed, and communication environment. The server dynamically recalculates transmission schedules for each vehicle as their conditions change, ensuring that the scheduling adapts to the current state of each vehicle rather than using a fixed approach.
2Device complexity
If locations where vehicles are traveling are not used for scheduling, then the scheduling process is simpler, but wasteful communication may be performed on in-vehicle devices mounted on vehicles traveling through incommunicable regions
Solution Approach 1:
The server performs preliminary scheduling by determining transmission schedules in advance based on predicted vehicle locations and communication conditions. By using location information to pre-calculate which vehicles can receive information and when, the system avoids wasteful communication attempts with vehicles in incommunicable regions before they actually need the information.
Solution Approach 2:
The system uses feedback from vehicle location data and communication status to continuously optimize the transmission schedule. The server receives location information from each vehicle and adjusts the transmission schedule based on this feedback, ensuring that communication resources are not wasted on vehicles that cannot receive transmissions due to being in incommunicable regions.
3Device complexity
If the type of information requested for transmission is not used for scheduling, then the scheduling is simpler, but when information that needs to be provided in real time is presented on an in-vehicle device, the information may not be able to be transmitted at appropriate timing
Solution Approach 1:
The patent applies local quality by assigning different priorities to different types of information based on their specific requirements. Critical real-time information such as safety alerts or traffic conditions is given higher priority and scheduled for immediate transmission, while non-urgent information like map updates or entertainment content receives lower priority. This allows the scheduling system to treat different information types differently according to their specific needs.
Solution Approach 2:
The system changes the scheduling parameters dynamically based on the type of information being transmitted. By analyzing the information type and its urgency requirements, the server adjusts transmission timing, bandwidth allocation, and priority levels accordingly, ensuring that real-time information is transmitted at appropriate timing while maintaining efficient overall system operation.

AI summary
A receiving unit (20) receives pieces of request information indicating pieces of information requested by in-vehicle devices (3A to 3D) of vehicles (A to D) and pieces of condition information indicating the internal and external conditions of the vehicles (A to D). A delivery control unit (21) sets priorities for information transmission for types of respective pieces of information indicated by the pieces of request information and for the internal and external conditions of the vehicles (A to D) indicated by the pieces of condition information, and determines a transmission schedule for transmitting pieces of information to the in-vehicle devices (3A to3D), on the basis of the priorities. A transmitting unit (22) transmits the pieces of information to the in-vehicle devices (3A to 3D), according to the transmission schedule.
