Description
Technical field
The present invention relates to a kind of CAN Bus in Electric node general purpose controller, it is mainly used in replacing the biography of electric automobile
System wire harness, realizes that On-board LAN network is controlled nearby with the integrated distribution formula of vehicle mounted electrical apparatus.
Background technology
Traditional automotive wire bundle is all a pretty troublesome thing from installation is fabricated into.First, the system of automotive wire bundle
Make process major part need of work to make by hand, it is impossible to all replaced with machine；Second, connecting institute on a current sedan limousine
The holding wire of some electronic installations and equipment will be numerous equivalent to more than 20 times of past automotive wire bundle more than more than 1000
Wire harness be inherently a problem with its reliability that is coupled of vehicle mounted electrical apparatus equipment, not only cause safeguard on difficulty, it is prior
It is to turn into the further lightweight of automobile and the maximum obstacle of electronization.Therefore, from late 1980s, German Bosch
(Bosch) company takes the lead in proposing a kind of many console controller localized network agreement CAN (Controller Area Network),
And hot technology in the ascendant is quickly formed, and it is perfect by exploitation for many years, it is total as automobile full digital scene at present
The control instrument of line and the interconnection specification of equipment, are international bus standards that International Organization for standardization uniquely adopts and recognizes.
From network physically, CAN belongs to bus type communication network, this be one have very high reliability, protect
Close property, error detecing capability, can effectively support the how main serial communication link of distributed AC servo system or real-time control, i.e., substantial amounts of automobile
Internal on-site signal connection cable, is replaced by single succinct fieldbus networks, so as to mitigate on-site signal connection significantly
Cumbersome and cost, improve signal transmission precision.CAN is both different from traditional simulation 4mA-20mA electric current loops, and not
It is same as BITBUS BITBUS networks and principal and subordinate's RS-485 agreements.In 4mA-20mA electric current loops, a signal can only be typically carried, generally
It is process variable, and CAN is while transmission variables process, the identifier and diagnosis execution information of instrument can also be passed in the lump
Send.The accuracy of data signal than 4mA-20mA analog signal high resolutions, therefore, make automobile field intelligent instrument turn into can
Energy.On the other hand, it is a kind of one kind dedicated for industrial automation that CAN is embodied in it with general network-critical difference
Network, but used different from Information Processing Network, such as Ethernet, Internet etc., its physical characteristic and procotol characteristic
Unique hardware design, especially with non-destructive arbitration technique, when two nodes simultaneously to data are transmitted on network when,
The low node of priority actively stops data is activation, and priority node high unaffected can continue to transmit data, effectively keep away
Bus collision is exempted from；When node is in the case where occurring gross error, with automatically cutting off the function that the node and bus are contacted,
So that other operations are unaffected in bus, its reliability is far above outmoded on-scene communication technology.Therefore, China " 863
Plan " clearly proposes that the electric motor car exploration project newly declared must be logical using CAN in the explanation on electric automobile
News pattern, i.e., realize the data communication between automotive interior control system and each detection and executing agency with CAN.
The content of the invention

CAN Bus in Electric node general purpose controller be fixed on vehicle frame.
About gone up in control plan, the maximum characteristic of the present invention is that not only had more main parallel reciprocity control model but also had distribution
The control model of formula architecture.Embedded-type ARM chip based on CAN2.0B kernels（60）The built-in parallel control of many masters is soft
Part, thus each CAN node general purpose controller can autonomous call peer, realize the redundancy cooperation of system；In distribution
Under architecture molding formula, then it is responsible for controlling electric vehicle system nearby by each CAN node general purpose controller
Task.
The basic ideas of inventive network design of the management software are as follows, and CAN core telecommunications module is assisted according to CAN first
Discuss sending and receiving for control data frame；Interface management logic module then provides the connection of ARM and VMOS driving chips, and ARM leads to
Cross all of CAN registers of Read-write Catrol logical access；Sending buffering area can store 1 complete amplifying message, when ARM will
When seeking transmission message, be sent to the message sent in buffering area in CAN by interface management logic manipulation CAN nucleus modules；
When a message is received, the serial bitstream data in bus is changed bit parallel data by CAN nucleus modules first, is then given
Receive filtering module to be identified, whether the message that receives of decision is message classification required by CPU, and the message of all receptions can
First in first out round-robin queue is received to be stored in, according to different mode of operation and data length, the round-robin queue can deposit
Most 64 messages.
After network node learns that a packet is reached, can select to receive or abandon, this selection course is using CAN's
Acceptance filtenng function is realized.The selection of packet is realized in the logical link control sublayer of data link layer, is only met
The packet of certain condition can just be received by the node, and other packets are to be abandoned in bottom, therefore, as long as in sending node
For packet sets correct identifier, you can send it to one or more control nodes specified.It is specific to receive filtering
Operating process is as follows, ARM chips（60）Reception code registers inside indicating are supported to message with mask register is received
Filtering, unconcerned message is kept outside of the door.Filtering module is received by the most-significant byte of 11 bit identifiers of CAN message in this 2
The value deposited in register compares, and be made whether the judgement for receiving, the order for having received or data then according to message not
Same priority and command type are acted upon.
In sum, CAN Bus in Electric node general purpose controller proposed by the invention, is a kind of and automotive wire bundle
The CAN node control device being combined, embedded-type ARM chip and contactless Power Control skill based on CAN2.0B kernels
Art integrally combines, and CAN and Power Control are combined together, has substantial improvements to existing CAN node modules, is to passing
The optimal renewal product of system CAN node control module, this is a kind of brand-new vehicle mounted electrical apparatus work(based on CAN
Rate controller.
Part of the invention novel is to change over CAN module to divide the way of main control module and various functions module,
CAN Bus in Electric node general purpose controller passes through input side CAN socket and outlet side CAN socket series connection mould
Formula, directly instead of relay box, reduce cabling back and forth so that the overall wire sheaves of electric automobile are most saved.
The present invention also dexterously proposes what how a kind of vehicle-mounted private jack was connected with flange-cooled socket insertion
Novel structure, so that power control signal has easily been drawn, while significantly improving the radiating matter of power device VMOS again
Amount.
