TW201537465A - Method for downloading and updating application program of in-vehicle device - Google Patents

Abstract

The present invention relates to a method for downloading and updating an application program of an in-vehicle device. The method allows a mobile device i to install a micro application program specifically for management. When a network server provides an update file for an in-vehicle device, the network server pushes an update message to the mobile device so that a user may use the mobile device to download the update file and transfers the update file from the mobile device to the in-vehicle device through connection between the mobile device and the in-vehicle device for updating of a program. As such, a vehicle owner may download and update, by himself or herself, the program of the in-vehicle device, thereby eliminating the hassles of maintenance at a workshop.

Description

Application downloading method for vehicle device

The present invention relates to a method for downloading and updating an application of a vehicle device, and more particularly to a method for downloading and updating a program on a vehicle device by a vehicle owner, thereby eliminating the procedure and inconvenience of returning to the factory for maintenance.

According to the general vehicle host (also known as the vehicle equipment truck) installed in the car, when the program is found to be defective in use or the function needs to be upgraded, and to update the installed vehicle host, usually by the depot Send the memory card (SD card, USB disc or CD) with the update program to the car repair shop or dealer, and then the repair shop or dealer will inform the owner to return to the factory for updates.

In another way, the depot sends the update program to the diagnostic device of the repair shop through the network, and then updates the car's car host through the car connection diagnostic device of the repair shop, but both methods require a recall (call Back) When the car is returned to the maintenance factory, the program can be updated, and the maintenance personnel need to be trained and pay attention to the update, so the time and cost of the loss are enormous, and the owner is quite inconvenient.

For the operation technology of the mobile device using the online update program, related technologies such as TW Publication No. 201315630, TW Publication No. 201323267, TW I270010, TW M449960, TW Publication No. 201117046, TW I306357, TW M434698, TW M437575, TW M434698, TW M461081 The patent case has been disclosed, wherein the operation of using the mobile device for online update is technically mainly through the network mode of the mobile device. The group performs the online update operation.
