The invention is a MPC500 processor-type electric car multi-energy source power assembly control device, using 32-bit car special embedded microprocessor as kernel hardware, designing pair control bus, address / data bus extended interface, serial communication interface, BDM debugging port and various I / O signal interfaces to compose kernel mainboard, which is connected with the I / O extended board with dual-port RAM interface through board to board pin-type standard linker so as to compose the hardware platform, thus heightening system integrity, vehicle carrying reliability and system technical performance, and making the control device able to ECU of each component of electric car multi-energy source power system through the CAN bus interface and the dual-port RAM interface, heightening application flexibility and transplantability. It only need change necessary soft module, thus able to be applied to various electric cars.
Description
technical field [0001] The utility model relates to a microprocessor-type electric vehicle multi-energy powertrain control device, which belongs to the automotive electronic control technology, and particularly relates to the field of electric vehicle multi-energy powertrain control systems composed of fuel cells. Background technique [0002] As a new design concept, the powertrain control system has had a significant impact on the design and manufacture of automobiles. In June 2000, the Ford Motor Company of the United States pointed out in the start report of the MOBIES project that the development of the powertrain control system has become one of the core links in the automobile development process, and related research and development work has spread all over the world. However, "multi-energy powertrain control system" is a new system concept proposed by the national "Tenth Five-Year" 863 plan. This concept originates from the fact that traditional vehicles have only o...
