Vehicle dual-system compatible control method and system, storage medium and vehicle-mounted terminal

Abstract

The invention relates to the technical field of electronic information, in particular to a vehicle dual-system compatible control method, a vehicle-mounted host and a storage medium. The method comprises the following steps: respectively establishing a first system and a second system based on two independent processors; allocating a data interface connected to the first system to the second system; setting a microprocessor to communicate the first system and the second system, constructing a virtual screen program in the microprocessor to obtain touch coordinates in an application program ofthe second system from the first system, converting the format of the touch coordinates, and sending the converted touch coordinates to the second system to serve as touch input of the application program; the vehicle-mounted host comprises a display screen, a touch screen, an audio output assembly, a Linux processor, an Android processor and a microprocessor. The first system and the second system are integrated and applied to the vehicle-mounted host, the advantages of the two systems are considered at the same time, good stability and system independence are achieved, the vehicle-mounted host can be normally used under the condition that one hardware or software is damaged, and the performance of a processor does not need to be strictly required.

Description

Technical field[0001]The invention relates to the field of electronic information technology, in particular to a vehicle dual-system compatible control method, system, storage medium and vehicle-mounted terminal.Background technique[0002]At present, the system adopted by the vehicle-mounted host on the market is the Linux system or the Android system. Both products have corresponding advantages and disadvantages. The vehicle host using Linux system has the advantages of less hardware resources, low price and easy connection to Carplay and Android Auto, but its application software is less, especially map software; Android is adopted The vehicle-mounted host of the system has relatively rich application software, but has higher requirements for processor performance and memory. Neither of them can meet the needs of Carplay and Android Auto's mobile phone interconnection, the requirements for system stability and boot speed, and the need for a richer Android ecosystem.Summary of the i...

Problems solved by technology

Both products have corresponding advantages and disadvantages. The vehicle-mounted host using the Linux system has the advantages of less required hardware resources, low price, and easy connection to Carplay and Android Auto, but there are few application software, especially map software; The on-board host of the system has relatively rich application software, but has high requirements for processor performance and memory

Neither of them can meet the needs of Carplay and Android Auto for mobile phone interconnection, the requirements for system stability and boot speed, and the needs for a richer Android ecosystem.
