Embodiment
[0036] Embodiment: a kind of centralized vehicle body control system of this embodiment, such as figure 2 As shown, it includes a body CAN network 1, a combination meter 10 and several BCM modules 11, and the BCM modules are all connected to the combination meter through the body CAN network. The combined meter includes a controller for processing vehicle body information and a memory storing a logic control program. The BCM module is composed of an information collection unit, an execution unit and a CAN transceiver, and the information collection unit and the execution unit are connected to the CAN Transceiver connection, the CAN transceiver is connected to the body CAN network.
[0037] In addition to the functions of ordinary instruments, the combination meter also integrates logic control functions and vehicle body information processing functions. The combined instrument can collect the information collected by each BCM module and sent to the CAN network of the vehicle...

The invention discloses a centralized body control system and an identity early warning method thereof. The system comprises a body CAN network, a combined meter and a plurality of BCMs (body control module), wherein the BCMs are all connected onto the combined meter via the body CAN network; the combined meter comprises a controller for processing body information and a storage device for storing a logic control program; each BCM is composed of an information acquisition unit, an execution unit and a CAN transceiver, the information acquisition unit and the execution unit are both connected with the CAN transceiver, and the CAN transceiver is connected onto the body CAN network; apart from functions of the existing combined meter, a logic control function and a body information processing function are also integrated in the combined meter; and the execution unit of the BCM outputs power for driving power consumption equipment of the vehicle. The control core is all transferred to the combined meter, all BCMs and BCMs on different vehicle types can be fully consistent, and the cost is reduced. The system and the method can be applied to all vehicles.
Description
technical field [0001] The invention relates to an automobile control circuit, in particular to a centralized vehicle body control system and an identity early warning method thereof. Background technique [0002] Compared with the distributed body control system, the centralized body control system has the characteristics of low cost, a small number of BCM modules, and a large number of electrical equipment that can be driven by a single BCM module. Therefore, centralized body control schemes are mostly used on commercial vehicles (such as passenger cars, buses, tourist buses, etc.) with a lot of electrical loads. [0003] The traditional centralized body control module (BCM, BodyControlModule for short), mainly has the functions of signal acquisition, power drive, logic control and so on. [0004] The network topology of the commercial vehicle centralized body control system commonly used at present is as follows: figure 1 shown. Since the electrical equipment of commer...
