Embodiment
[0036] Embodiment: A centralized 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 combination 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 acquisition unit, an execution unit and a CAN transceiver. The information acquisition unit and execution unit are both connected to the CAN The transceiver is connected, and the CAN transceiver is connected to the body CAN network.
[0037] In addition to the functions of ordinary instruments, the combination instrument also integrates logic control functions and body information processing functions. The combination meter can collect the information collected by each BCM module and send it to the body CAN network, and then aggregat...

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 body control system and an identity 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 devices that a single BCM module can drive. Therefore, centralized body control schemes are mostly used in commercial vehicles with more electrical loads (such as passenger cars, buses, tourist buses, etc.). [0003] The traditional centralized body control module (BCM, Body Control Module for short) mainly has functions such as signal acquisition, power drive, and logic control. [0004] The network topology of the commonly used centralized body control system for commercial vehicles is such as figure 1 Shown. Because the electrical equipment of commercial vehicles is mostly concentrated in the front...
