Cabin area controller system based on X9 platform and Xen technology and application method

Abstract

The invention relates to a cockpit domain controller system based on an X9 platform and an Xen technology and an application method. The cockpit domain controller system comprises a hardware system and a cockpit domain controller, wherein the cabin area controller comprises a core processor, a DDR chip and an MCU chip. The hardware system, the DDR chip and the MCU chip are electrically connected with the core processor; a Xen Hypervisor and a plurality of operating systems are loaded in the core processor; the core processor carries out CAN communication, signal acquisition and preprocessing through the MCU chip, and the DDR chip controls the hardware system by operating an operating system in the core processor. A plurality of operating systems such as Linux and Android are operated at the same time through virtualization of Xen, information sharing between any screens and non-delay transmission of data and images are achieved, instruments, display screens and the like in a cabin form a whole, construction cost is reduced, and cost performance is improved; the cabin controller system is based on UWB technology digital key system integration, and a vehicle owner can complete vehicle unlocking without taking out a key or a mobile phone.

Description

technical field [0001] The invention relates to the technical field of vehicle intelligent cockpit, in particular to a cockpit domain controller system and application method based on X9 platform and Xen technology. Background technique [0002] With the development of the automobile industry, especially the rapid promotion of new energy vehicles, consumers have higher and higher requirements for the interior space of automobiles. The interior cockpit space of a car not only needs to meet the needs of driving, but also needs to be continuously improved to become a comprehensive platform with multiple functions of transportation, entertainment, office and communication. [0003] The automotive electronic architecture is changing from the past distributed discrete control to the centralized domain controller architecture. The vehicle cockpit domain controller divides the vehicle into different functional domains. The car cockpit domain is usually equipped with multiple electr...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a cockpit domain controller system and application method based on the X9 platform and Xen technology, so as to solve the problem that the existing traditional cockpit control system needs to use two sets of equipment to operate the instrument system and the central control system respectively. Each system is equipped with a processor, and the instrument system and the central control system run on different processor hardware. Using multiple processors limits some functions and effects, resulting in reduced scalability and increased difficulty in overall car design. Large size, substantial increase in construction costs, and insufficient use of smart cockpit applications
