Parking Position Selection for Vehicle Charging and ECU Updates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In parking lots with both power supply facilities having and lacking data communication functions, vehicles requiring software updates face challenges in determining appropriate parking positions for efficient power supply and data communication.
Innovation Solution
A parking position determination device that includes a necessity determination unit to assess software update needs and a parking position determination unit to select between parking spaces with and without data communication functions, considering charging and update times, to optimize parking based on these requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the parking position determination device directs vehicles to parking spaces with data communication functions for software updates, then software update capability is improved, but parking space availability and flexibility deteriorate
Solution Approach 1:
The parking lot is segmented into two distinct types of parking spaces: first parking spaces equipped with data communication functions for software updates, and second parking spaces without data communication functions. This segmentation allows vehicles to be directed to appropriate parking spaces based on their specific needs, ensuring that vehicles requiring software updates utilize the specialized infrastructure while other vehicles can use standard parking spaces, thereby maintaining overall system flexibility and availability.
2Reliability
If the vehicle waits for software update completion during charging, then software update reliability is improved, but charging efficiency and time consumption deteriorate
Solution Approach 1:
The system dynamically adjusts the charging process based on software update status. When a vehicle parks in a first parking space with data communication function, the system determines whether software update is necessary and controls the power supply facility to prioritize either software update completion or charging efficiency based on real-time conditions. This dynamic control allows the system to flexibly switch between update-focused mode and charging-focused mode, optimizing overall productivity while ensuring updates are completed when resources are available.

AI summary
A parking position determination device determines a parking position of a vehicle parked for power supply in a parking lot including a first parking space provided with a first power supply facility having a data communication function that provides update data for software of an in-vehicle ECU to the vehicle, and a second parking space provided with a second power supply facility that does not have the data communication function. The parking position determination device includes a necessity determination unit that determines whether software update is necessary, and a parking position determination unit that determines the first parking space as the parking position of the vehicle when determination is made that the software needs to be updated, and determines the second parking space as the parking position of the vehicle when determination is made that the software does not need to be updated.
