Research on Intelligent ECU for Engine Based on CAN
As the core of automotive engine control system, carrying out intelligence research for ECU’s own intellectual property rights is necessary. In the foundation of combining domestic actual and analysis and summary to the existing system, we propose the design proposal of motor car engine intelligence electron controller based on CANBUS, and exposit how the factors of human, automobile, environment and so on to be coordinated to achieve optimal performance of overall system. By computer communication and network technology, seamlessly integration of GPS navigation system, radio telephone and bus distributed network can be realized, which enables the entire automobile electron system have the ability of data fusion, failure diagnosis and certain self-repair ability. ECU has huge potential commercial profit, because it uses field bus technology so that cable quantity in automobile was reduced greatly, and the field bus uses pure digital technique so that many measuring appliances and equipments can be connected on single electric cable to transmit more information, in addition, it has stronger interference immunity, lower cost of installment, running and maintenance. This system can coordinate with transportation automatic monitoring visual system, and it’s the key link to realize intelligence transportation system.
