UC.GS.1

Utilization of current location information

The driver uses the navigation application and sets the destination. The user starts the application, enters the destination, and the time required and route are displayed.

UC.GS.2

Acquisition of GPS time

IVI system obtains the GPS time and corrects the display of the time on the IVI display screen. It can also be used for other way as "expiration date" for credentials by openssl or abs time of linux, etc. as examples.

UC.GS.3

DeadReckoning

A driver drives a car to a destination. If the driver enters a tunnel or other place where it is difficult to receive a signal and GPS information cannot be obtained, the driver can use the Sensor information obtained to position the car.

UC.GS.4

Utilization Retention of retained GPS information

When the driver presses the button for ACC-OFF, the IVI system retains the GPS information. When the driver presses the button for ACC-ON, the current location information will be displayed based on the retained information.

RQ.GS.1

GPS and Sensor data distribution registration

UC.GS.1, UC.GS.2, US.GS.3

GPS and Sensor communication module shall be able to register the delivery of GPS(including time) and Sensor data to the application that wants to receive them.

RQ.GS.2

Utilization of the function from the application

UC.GS.1, UC.GS.2, US.GS.3

GPS and Sensor communication module shall send the necessary GPS(including time) and Sensor data to the registered applications.

RQ.GS.3

Acquisition of GPS data and Sensor data

UC.GS.1, UC.GS.2, US.GS.3

GPS and Sensor communication module shall receive GPS and Sensor data transmission requests from applications.

Dead Reckoning function is not provided by this system, and needs to be implemented separately. Since acquired GPS and Sensor data, etc. are required, the data will be provided when the request is sent from the system owning Dead Reckoning function. 

RQ.GS.4

Provision of GPS data and Sensor data

UC.GS.43

GPS and Sensor communication module shall receive the GPS and Sensor data transmission request from the application and provide the necessary data.

GPS and Sensor communication module retains GPS information when the ACC is turned OFF from ON, and provides GPS information when the ACC is turned ON.
