In-Vehicle Task Management Device for Dynamic Priority Scheduling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In-vehicle multimedia devices face excessive processing loads due to frequent interruptions from traffic information, leading to potentially inappropriate task priority settings based on vehicle traveling situations, which can result in inefficient resource allocation and increased processing burdens.
Innovation Solution
A task management device and method that acquires vehicle information to generate and transmit instruction information for setting task priorities in in-vehicle multimedia devices, dynamically adjusting priorities based on vehicle location, road conditions, and usage history to optimize resource allocation and reduce processing loads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traffic information is frequently input to the in-vehicle device by interruption, then the traffic information can be notified to occupants timely, but the processing load of the in-vehicle device becomes excessively high
Solution Approach 1:
A task management device is introduced as an intermediary between the beacon device and the in-vehicle multimedia device. This mediator receives task information from the beacon device, determines appropriate execution priorities based on vehicle information, and transmits prioritized tasks to the multimedia device, thereby distributing the processing burden and preventing excessive load on the in-vehicle device
Solution Approach 2:
The task management device performs preliminary determination of task execution priorities before the tasks are executed by the in-vehicle multimedia device. By pre-processing and prioritizing tasks based on vehicle information in advance, the system avoids the need for real-time priority adjustments during execution, reducing the processing load on the in-vehicle device
2Ease of operation
If task priorities are determined based on predetermined rank and level, then task execution order can be managed, but the priority setting may be inappropriate depending on the traveling situation of the vehicle
Solution Approach 1:
The task execution priority is made dynamic rather than static. The task management device determines priorities based on current vehicle information such as vehicle speed, which changes with traveling situations. This dynamic adjustment allows the system to adapt priority settings to different driving conditions, making the system both easy to operate and highly adaptable
Solution Approach 2:
The system changes the parameter used for priority determination from fixed predetermined ranks to variable parameters based on actual vehicle information. By using vehicle speed and other dynamic parameters to determine priority, the system maintains simple operation while achieving high adaptability to different traveling situations
