Abstract

The invention provides an overall vehicle bus control system. The overall vehicle bus control system comprises a power CAN network, a vehicle body CAN network, a diagnosis CAN network, a BCM LIN network and a PEPS LIN network. By the adoption of the CAN/LIN bus system and the adoption of two network management methods and the unified diagnostic criteria in three CAN bus systems and two LIN bus systems, the overall vehicle cost can be reduced effectively, wire harness resources can be saved effectively, information transfer and resource sharing among nodes of all the buses can be realized, operation of power units and operation of vehicle body units can be coordinated, and a vehicle can be driven to travel normally.

Description

technical field [0001] The invention relates to the field of vehicle control equipment, in particular to a vehicle bus control system. Background technique [0002] The existing bus system cannot fully match the actual needs of new models, and cannot reduce costs more effectively. The bus system in this application is a bus system re-developed to match the new model, which has changed a lot compared with the existing bus system. For example, there are 3 CAN and 2 LIN buses. How to save the cost and cost of the whole vehicle more effectively? Harness resources, and accurate and reasonable control of these bus nodes and make them work normally are the main problems to be solved. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a vehicle bus control system. The present invention is re-developed for the purpose of effectively saving the cost of the vehicle and wiring harness resources, realizing information transmiss...
