Abstract

The invention relates to a vehicle control system based on redundancy reconfiguration and a control method, belongs to the technical field of vehicle-mounted equipment communication and control, and solves the problems that the single-point failure risk exists in an existing vehicle control system, a control instruction and a query instruction sent by the comprehensive processor equipment of the system are outputted to the terminal controller equipment through gateway controller equipment and network bridge equipment; the comprehensive processor equipment comprises a first processor and a second processor which are mutually backed up; the gateway controller equipment comprises a first gateway controller and a second gateway controller which are mutually backed up; the network bridge equipment comprises a first network bridge and a second network bridge which are mutually backed up; the first processor, the second processor, the second gateway controller, the second network bridge, the first network bridge and the first gateway controller are respectively used as network nodes and are sequentially connected to form a bidirectional ring network. The system redundancy is increased, the overall reliability is improved, and the communication network rate and bandwidth of the whole vehicle are improved.

Description

technical field [0001] The invention relates to the technical field of vehicle equipment communication and control, in particular to a reconfigurable vehicle control system and control method based on redundancy. Background technique [0002] At present, new demands are constantly emerging for special vehicles in terms of informatization and intelligence. Information interaction between sub-systems and devices within the system is closer, communication and control are more complex, and higher requirements are placed on the usability and reliability of vehicles. Require. [0003] At present, most vehicle control systems still have single-point links. In order to avoid single-point failures, some systems directly implement dual-redundant or even triple-mode redundant configurations for all single-point links. Although this can solve the problem, it will also increase the hardware scale and cost exponentially. [0004] Reconfigurable is to reorganize the internal structure or...
