Vehicle instrument interface theme display system and method, central controller and instrument terminal device

Abstract

The embodiment of the invention discloses a vehicle instrument interface theme display system and method, a central controller and an instrument terminal device, and relates to the technical field ofvehicles. The method comprises the following steps that: a vehicle-mounted central control device downloads instrument interface theme and skin resources from a server; and a vehicle-mounted instrument terminal receives and stores the instrument interface theme and skin resources transmitted by the vehicle-mounted central control device, and loads the instrument interface theme and skin resourcescorresponding to a display control instruction sent by the vehicle-mounted control device to display. According to the method, the system and the terminal disclosed by the invention, themes and skinsare stored through the vehicle-mounted instrument terminal, and a theme and skins displayed by the vehicle-mounted instrument terminal are switched with the central control device, so that a user canselect a favorite theme interface conveniently, and a switching operation is more intuitive and convenient. Through adoption of a plug-in architecture, the themes can be switched rapidly and dynamically; extension is facilitated; and an instrument does not need to be restarted. Hackers can be prevented from attacking a vehicle to directly control the instrument, thereby making network architecturemore secure.

Description

technical field [0001] The present invention relates to the technical field of vehicles, in particular to a vehicle instrument interface theme display system, method, and central control and instrument terminal devices. Background technique [0002] With the development of LCD screens, more and more car instrument screens are replaced by LCD screens. The interface themes of the LCD screen are solidified and stored in the meter when the meter leaves the factory. However, users may not like the instrument interface theme stored in the factory, and hope to update it to their favorite interface theme. When the theme of the vehicle instrument interface is updated, it is necessary to remove the instrument and return it to the factory for update or the engineer will update it through a professional update tool, which is inconvenient for users to update by themselves and cannot meet user needs. Or, store a set of theme interface locally on the instrument terminal. When updating th...

When the theme of the vehicle instrument interface is updated, the instrument needs to be removed and returned to the factory for update or the engineer can update it through a professional update tool, which is inconvenient for users to update by themselves and cannot meet user needs

Or, store a set of theme interface locally on the instrument terminal. When updating the vehicle instrument interface theme, the instrument directly establishes a network connection with the server, and downloads the pre-downloaded instrument interface theme on the instrument terminal. After the update is completed, the instrument terminal automatically Restart, and the updated theme will be displayed after restarting; if the user wants to change another favorite theme, he can only update from the server again, which is inconvenient to operate, and the instrument is directly connected to the server to obtain the theme, which has network security problems and is more vulnerable to hacker attack
