Abstract
An on-vehicle information processing unit includes a central processing unit; a first device connected to the central processing unit; a device-dependent driver for driving only the first device; an operating-system-standard (OS-standard) driver enabling an application to drive devices different from the first device; a device-dependent application using the first device through the device-dependent driver; and an OS-dependent application for using the first device through the OS-standard driver. The central processing unit can include a switch for enabling the OS-dependent application only when using an Internet function, and for operating the device-dependent application in a normal mode.
Claims9
An on-vehicle information processing unit comprising:
- a central processing unit;
- a first device connected to said central processing unit;
- a device-dependent driver for driving only said first device;
- an operating-system-standard (OS-standard) driver enabling an application to drive devices different from said first device;
- a device-dependent application using said first device through said device-dependent device;
- an operating-system-dependent (OS-dependent) application using said first device through said OS-standard driver, and
- driver switching means for switching between said device-dependent driver and said OS-standard driver, wherein said device-dependent application controls said driver switching means by carrying out inter-program communication with said OS-dependent application.
