Abstract

PURPOSE: A DIS(Driver's Information System) having a downloadable HMI(Human Machine Interface) and its downloading method are provided to allow a driver to change HMI software to his/her taste through a user terminal. CONSTITUTION: A DIS is driven(S210). When a driver selects one of multiple devices, namely, an air-conditioner, a DIS control unit drives an air-conditioner HMI software to display an air-conditioner HMI on an input/output terminal, and an air-conditioner application is driven to control the air-conditioner(S220). The DIS control unit determines whether the driver wants to change the air-conditioner HMI(S230). If the drive wants to change the air-conditioner HMI, the DIS control unit requests a list of download HMI software from an HMI server(S240). The HMI server transmits the requested list of the download HMI software(S250). The DIS displays the received HMI list through the input/output terminal and transmits driver's selected HMI software to the HMI server(S260). The HMI server transmits the received HMI software to the DIS(S280).

The air conditioner HMI is displayed on the input / output terminal 1100 by driving, and the air conditioner application 1273 is driven based on data input by the driver to control the air conditioner 2300. If the driver wants to change, update, or have an HMI with a different design, the driver may operate the air conditioner HMI to input data requesting the download of the air conditioner HMI. The DIS control unit 1200 determines whether the driver wants to change the air conditioner HMI based on the data input from the input / output terminal 1100 (S230), and determines that the driver wants to change the air conditioner HMI. In the case of requesting a list of HMI software for download to the HMI server 3000 (S240). The HMI server 3000 transmits a list of the HMI software for the air conditioner 2300 (S250). The DIS 1000 displays the transmitted HMI list through the input / output terminal 1100 and transmits the HMI software list selected by the driver to the HMI server 3000 (S260). The HMI server 3000 transmits the selected HMI software to the DIS 1000 (S270), and the transferred HMI software is stored in the DIS control unit 1200 of the DIS 1000 (S280). The HMI software downloaded and stored in the DIS control unit 1200 replaces or is stored with the previous HMI software 1273 and is driven according to the driver's choice.

The user terminal 4000 and the HMI server 3000 are connected to a network, preferably the Internet, to exchange data.

The user terminal 4000 may be separately prepared for ease of editing. However, the user terminal 4000 may be integrally formed with the DIS 1000 to edit HMI software directly in a vehicle.

4 is a flowchart of the HMI software editing method.

The driver accesses the HMI server 3000 using the user terminal 4000 and inputs driver information. The driver information may include identification (ID), password, vehicle information, and the like. The input driver information is transmitted to the HMI server 1000 via a network. The HMI server 1000 compares the transmitted driver information with the stored driver information and determines that the authentication succeeds, and if it does not match, determines that the authentication fails.

If it is determined that authentication is successful, the HMI server 1000 transmits HMI software information classified for each driver to the user terminal 4000.

The HMI software information is information about HMI software for a plurality of devices provided in a vehicle, and is implemented by a data table including fields for button ID, button image, button size, button position, and button function.

Preferably, the user terminal 4000 is provided with an application program for displaying and editing the HMI software information. The transferred HMI software information is displayed on the user terminal 4000 using the application program.

The operator operates the user terminal 4000 to select a device and edit HMI software information for the selected device.

The edited HMI software information is transmitted to the HMI server 1000 via a network.

The HMI server 1000 inspects the edited and transmitted HMI software information based on the set criteria. The set criterion includes one or more of whether or not the image data of the button is damaged, the button size, whether the button position coordinates exist in the vehicle display unit, whether the buttons overlap, or whether the data table field is empty.

If the set criteria do not match, the HMI server 1000 transmits a failure message to the user terminal 4000.

If the set criteria are met, the HMI server 1000 changes and stores the HMI software based on the edited and transmitted HMI software information.

The changed and stored HMI software is transferred to the DIS of the vehicle by the aforementioned HMI software download method, and the HMI software stored in the vehicle is changed.
