Abstract
The utility model provides a kind of CAN communication network, including main control module, CAN communication harness and it is multiple from control module, CAN communication harness includes CAN High and CAN Low, the main control module is connect with CAN High, the CAN Low respectively, it is described to be connect respectively with CAN High, the CAN Low from control module, it is described to be integrated with terminal resistance and external cabling mouth from control module.Compared with prior art, originally the terminal resistance being arranged on individual pcb board is integrated into from control module by the utility model, the design of pcb board is omitted, reduce the cost at entire CAN communication network, simultaneously, due to directly omitting entire pcb board, the space hold at entire CAN communication network is also further reduced, and light-weighted target is furthermore achieved.
Description
Technical field
The utility model belongs to electrical device of electric vehicle control field, more particularly, to a kind of CAN communication network.
Background technique
Higher and higher to the design requirement of vehicle with the continuous development of new-energy automobile, low cost, lightweight, which becomes, to be set
The target that meter scheme is pursued.CAN communication network because its strong real-time, anti-electromagnetic interference capability is strong, error detecing capability is strong the advantages that
It is widely used in new-energy automobile communication, and in the CAN communication Terminal Design at entire CAN communication network needs that end is arranged
Build-out resistor is held, the design scheme of current terminal coupling resistance redesigns an independent pcb board substantially to assemble terminal
Build-out resistor, then pcb board is connected in CAN communication network.Such design scheme will increase setting for an individual pcb board
Meter improves design cost, meanwhile, pcb board itself needs to occupy certain space, can cause to the spatial arrangement of entire battery case
It influences, is unfavorable for light-weighted realization.
Summary of the invention
In view of the deficiencies of the prior art, the utility model provides a kind of CAN communication network, can reduce CAN communication network
Design cost, while occupied space can be reduced, realize lightweight target.
The utility model provides a kind of CAN communication network, including main control module, CAN communication harness and multiple from control
Module, CAN communication harness include CAN High and CAN Low, the main control module respectively with CAN High, the CAN
Low connection, it is described to be connect respectively with CAN High, the CAN Low from control module, which is characterized in that described from control mould
Block is integrated with terminal resistance and external cabling mouth.
Further, the terminal resistance is connect with the CAN communication harness and the external cabling mouth respectively.
Further, the external cabling mouth is connect with the CAN communication harness.
Compared with prior art, the utility model by the terminal resistance being arranged on individual pcb board originally be integrated into from
It controls in module, the design of pcb board is omitted, reduces the cost at entire CAN communication network, simultaneously as directly omitting entire
The space hold of pcb board, entire CAN communication network is also further reduced, and light-weighted target is furthermore achieved.
