Single-SOC multi-operation system device based on commercial vehicle cabin

Abstract

A single-SOC multi-operation system device based on a commercial vehicle cabin comprises a central control system and an instrument system. Hardware of the central control system adopts an MCU subsystem and an MPU subsystem, software adopts an Android subsystem, and the central control system is used for displaying and controlling the central control of the commercial vehicle; and hardware of the instrument system adopts an MCU subsystem and an MPU subsystem, software adopts a Linux subsystem, and the instrument system is used for displaying and controlling commercial vehicle instruments. According to the single-SOC multi-operation system device based on the commercial vehicle cabin, the software implementation mode that a single SOC operates multiple operation systems is achieved through the SOC core separation technology, the technology can be applied to various multi-core heterogeneous CPUs, the cross-platform capacity is achieved, meanwhile, the problems of data communication and data sharing between the two systems are solved, and the security problems of inter-system security access and system stability are improved.

Description

technical field [0001] The invention relates to the field of commercial vehicles, in particular to a single SOC multi-operating system device based on a commercial vehicle cockpit. Background technique [0002] At present, the intelligent virtual cockpit system in the automotive industry is a product in the process of developing from the traditional vehicle electronic and electrical architecture to the new generation architecture of the domain controller. [0003] This product will redefine the relationship between the user and the car. The layout of traditional car cockpit functional areas is fragmented, and information overload brings obstacles to human-vehicle interaction, making smartphones the entrance for human-vehicle interaction. With the improvement of the electronic degree of automobiles, a multi-product fusion smart cockpit domain controller integrating LCD instrumentation, central control screen and surrounding image functions. [0004] In the field of commerci...

Problems solved by technology

[0007] Using multiple SOCs to lay out boards on the same hardware design, each SOC drives an operating system and a corresponding LCD screen, and uses an illusion to realize the product of the smart cockpit; the defect is that it does not meet the concept of product definition, The superficial smart cockpit product realized by changing the concept is actually consistent with the traditional single instrument and single central control solution, and the increased product cost and system instability caused by the complexity of the single board design;

[0008] Adopt virtualization technology, use third-party software solutions, and configure software resources on the same SOC to realize virtual multiple operating systems and multiple LCD screens on one SOC; the disadvantage is that the core technology of third-party software solutions is mastered in foreign countries There are a few companies with a cost of several million. The support for customization needs is poor, and it is difficult to meet the flexible and changeable needs of customers. Innovation and service support are weak. industry, it is easy to be "stuck" by it;

[0009] Using the way of driving multiple display screens, drive multiple screens on the same SOC, and use the same operating system to realize the functions of smart cockpit products; the defect is that the main components of smart cockpit products are instruments and central control, and instruments are in the auto parts It belongs to the safety part, and the central control belongs to the entertainment part and has networking function and complex functions. It is realized by using the same operating system, which brings safety hazards to the safety part of the instrument.
