Embodiment Construction

[0039] see Figure 1 to Figure 5 As shown, a kind of vehicle bus control system management method of the present invention realizes direct network management through CAN bus network 11 and LIN bus network 12 structure that both are electrically connected; comprises the following steps:

[0040] Step 10, the CAN bus network 11 includes a first node 1111 and a second node respectively connected to the body control module 111 (ie BCM), the one-key start system module 112 (ie PEPS) and the instrument control module 113 (ie METER) 1121 and the third node 1131; the LIN bus network 12 includes a master node 121 connected with the body control module 111 and a slave node 122 connected with the combination switch control module 114 (ie COLUMN SW ECU);

[0041] Step 20,

[0042] a1. When the electric door lock (i.e. IG SW) is turned on (i.e. the key is in the IG on state), the master node 121 wakes up the slave node 122;

[0043] a2. When the small light or high beam in the combinatio...

Abstract

The invention provides a management method for a bus-mastering system of a finished automobile. According to the management method, network management is realized through a CAN (controller area network) bus network structure and an LIN (linear) bus network structure which are electrically connected with each other. The management method has the advantages that requirements on a novel automobile type are met, network management is adopted, the recovery time of network from sleep to awaken is fast, and power saving can be realized.

Description

【Technical field】 [0001] The invention relates to the field of automobile electronics, in particular to a method for managing a bus control system of an automobile. 【Background technique】 [0002] The existing CAN and LIN bus management systems cannot fully match the actual needs of new models, and the old CAN and LIN network management methods consume more power. The nodes in the network need better management methods from sleep to wake-up state to achieve energy saving. purpose of electrical efficiency. 【Content of invention】 [0003] The technical problem to be solved by the present invention is to provide a method for managing the bus control system of an automobile. Let the vehicle bus control system meet the needs of new vehicles, respond faster and save power. [0004] The present invention is achieved like this: a kind of automobile whole vehicle bus control system management method realizes direct network management through the CAN bus network and the LIN bus ne...
