Display control device, and display control method
First Claim
1. A display control device for controlling a display of a display unit mounted in a vehicle, including a dedicated middleware that executes a program prepared on a vehicle side, a general purpose middleware that executes a plurality of general purpose application programs delivered from an external of the vehicle, and an interface that exchanges necessary information between the dedicate middleware and the general purpose middleware, the display control device comprising:
- an acquisition device that acquires vehicle information associated with the vehicle on a dedicated middleware side;
a notification device that notifies a general purpose middleware side through the interface of a vehicle status based on the vehicle information acquired by the acquisition device;
an activation device that activates, on the general purpose middleware side, a target application program for realizing the display corresponding to the vehicle status among the general purpose application programs based on the vehicle status notified by the notification device; and
a general operating system, the dedicated middleware and the general purpose middleware being located on the general operating system, the dedicated middleware and the general purpose middleware being independent from each other, and the general operating system being a software operating system;
wherein;
exchange of the necessary information between the dedicated middleware and the general purpose middleware is performed through only the interface when an amount of the necessary information is lower than a predetermined threshold; and
the exchange is performed through both the general operating system and the interface when the amount of the necessary information is equal to or higher than the predetermined threshold.

Abstract
A display control device for controlling a display unit in a vehicle, including a dedicated middleware that executes a program on a vehicle side, a general purpose middleware that executes general purpose application programs from an external of the vehicle, and an interface that exchanges necessary information between the dedicate middleware and the general purpose middleware, includes: an acquisition device that acquires vehicle information on a dedicated middleware side; a notification device that notifies a general purpose middleware side through the interface of a vehicle status based on the vehicle information; and an activation device that activates, on the general purpose middleware side, a target application program for realizing the display corresponding to the vehicle status among the general purpose application programs based on the vehicle status.

7. A display control method for controlling a display of a display unit mounted on a vehicle, comprising:
-
acquiring vehicle information associated with a vehicle by a dedicated middleware that executes a program prepared on a vehicle side; notifying a general purpose middleware, which executes a plurality of general purpose application programs delivered from an external of the vehicle, of a vehicle status based on the vehicle information through an interface; exchanging necessary information between the dedicated middleware and the general purpose middleware through the interface; and activating a target application program, by the general purpose middleware, for realizing the display corresponding to the vehicle status among the general purpose application programs based on the vehicle status; wherein the dedicated middleware and the general purpose middleware are located on a general operating system, the dedicated middleware and the general purpose middleware are independent from each other, and the general operating system is a software operating system; and wherein; exchange of the necessary information between the dedicated middleware and the general purpose middleware is performed through only the interface when an amount of the necessary information is lower than a predetermined threshold; and the exchange is performed through both the general operating system and the interface when the amount of the necessary information is equal to or higher than the predetermined threshold.
