Abstract
The utility model relates to a local interconnect network (LIN) bus central electric box, which is arranged between a vehicle body controller and loads. The central electric box comprises an LIN transceiver, a relay driving module and at least one relay, wherein the input end of the LIN transceiver is connected with the vehicle body controller through an LIN bus; the output end of the LIN transceiver is connected with the relays through the relay driving module; and the relays are connected with the loads. Compared with the prior art, the central electric box has the advantages of reducing the number of wire harnesses of the whole vehicle, saving cost of the whole vehicle, more flexibly controlling the relays and the like.
Description
Technical field
The utility model relates to auto parts and components, especially relates to the central electrical box of a kind of LIN bus.
Background technology
Central authorities' electrical box is the vitals of automotive control system.Traditional central electrical box is owing to be connected with car body controller through rigid line; Increased the car load wire harness greatly; Thereby cause the increase of integral vehicle cost, simultaneously because traditional central electrical box is not carried out signal to output relay and returned inspection, so precise control property reduces greatly.And traditional central electrical box system compatibility is poor, is only applicable to identical or close vehicle among a small circle.
The utility model content
The purpose of the utility model is exactly for the defective that overcomes above-mentioned prior art existence a kind of reduction car load wire harness quantity, saving integral vehicle cost, relay control LIN bus central authorities electrical box more flexibly to be provided.
The purpose of the utility model can realize through following technical scheme: the central electrical box of a kind of LIN bus; Be arranged between car body controller and the load; It is characterized in that this central authorities' electrical box comprises LIN transceiver, relay driving module and at least one relay, the input end of described LIN transceiver is connected with car body controller through the LIN bus; The mouth of LIN transceiver is connected with relay through relay driving module, and relay is connected with load.
Described load comprises car light, air-conditioning and motor.
Described at least one relay comprises 1～200.
Compared with prior art, the utlity model has following advantage:
1, system compatibility is strong, is suitable for multi-platform vehicle;
2, reduce the BEC IO interface, thereby reduce car load wire harness quantity, practice thrift integral vehicle cost;
3, can carry out signal to output relay and return inspection, more reliable;
4, relay control is more flexible.
Description of drawings
Fig. 1 is traditional central electrical box system architecture scheme drawing;
Fig. 2 is the structural representation of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is elaborated.
Embodiment
As shown in Figure 2, the central electrical box of a kind of LIN bus is arranged between car body controller 1 and the load 5, and this central authorities' electrical box comprises LIN transceiver 2, relay driving module 3 and at least one relay 4.The input end of LIN transceiver 2 is connected with car body controller 1 through the LIN bus, and the mouth of LIN transceiver 2 is connected with relay 4 through relay driving module 3, and relay 4 is connected with load 5.Load comprises current consumers such as car light, air-conditioning, motor.Relay comprises 100.
The utility model is through increasing the Based Intelligent Control function on the basis of the automobile central electrical box of traditional scheme, can realize more flexibly, reliable, reduces the target of integral vehicle cost.LIN bus central authorities electrical box increases micro controller module on the conventional central electrical box; Carry out the information transmission with car body controller through the form of LIN bus; Replace and used the rigid line ways of connecting in the past, significantly reduced the car load wire harness, the reduction integral vehicle cost; Simultaneously can carry out signal and return inspection output relay, more reliable.
