Abstract

In a vehicle onboard apparatus, a connection detection function expands a specific file and activates an SSH connection function when a USB memory storing a specific file is connected, and thereby enables access to an application function from a general-purpose OS function during a period in which the USB memory is connected. A disconnection detection function stops the SSH connection function and deletes the SSH connection function when the USB memory is disconnected, and thereby disables access to the application function from the general-purpose OS function during a period in which the USB memory is not connected.

Claims

1. A vehicle onboard apparatus comprising:

an analysis tool connection portion to which an analysis tool that analyzes logs and data is connectable;

a recording medium connection portion to which a recording medium is connectable; and

a microcomputer having a general-purpose operating system function capable of activating a data communication function that transfers the logs and the data stored in an application function to the analysis tool,

wherein;

the vehicle onboard apparatus comprises

a connection detection function that detects connection of the recording medium to the recording medium connection portion, and

a disconnection detection function that detects disconnection of the recording medium from the recording medium connection portion;

when the connection detection function detects the connection of the recording medium to the recording medium connection portion and determines that a specific file protected by a password is stored in the recording medium, the connection detection function expands the specific file by using a predefined password, copies the data communication function included in the expanded specific file to a specific area of the general-purpose operating system function, and activates the data communication function; and

when the disconnection detection function detects the disconnection of the recording medium from the recording medium connection portion and determines that the data communication function is activated, the disconnection detection function stops the data communication function activated and deletes the data communication function from the general-purpose operating system function.
