AI Technical Summary

Technical Problem

Conventional OTA vehicle software updates face delays in displaying HMI data due to increased data size, which can prevent timely updates, especially in vehicles with short usage periods, and adding a CAN bus to increase acquisition speed results in additional costs.

Method used

An electronic control device that includes a detection unit to detect the vehicle's power supply state, a receiving unit to receive data based on this state, and a display control unit to manage data display, optimizing data acquisition speed by being faster when the power supply is OFF than when it is ON.

Benefits of technology

Reduces data acquisition time and enables quicker software updates without the need for additional hardware, such as a CAN bus, thereby reducing costs and ensuring timely updates even in vehicles with brief usage periods.

Abstract

To provide an electronic control device capable of shortening data acquisition time.SOLUTION: An electronic control device according to the present invention includes a detection unit that detects the state of a vehicle's driving power supply, a receiving unit that receives data transmitted from the outside on the basis of the state of the driving power supply, a storage unit that stores the data received by the receiving unit, and a display control unit that displays screen information based on the data in the storage unit on the condition that predetermined data is all collected by adding the data received by the receiving unit. Data acquisition speed by the receiving unit is faster when the driving power supply is off than when the driving power supply is on.SELECTED DRAWING: Figure 2
