FUJITSU TEN LIMITED(Headquarters:
Kobe, President: Keijiro Katsumaru, Capital: 5.3 billion yen) has
developed a high-speed simulation motor board “CORE-X”, with the
fastest processing capacity in the industry of 1μs and a motor model
specialized for equipping to this board, as a new option for the
automobile control ECU (Electronic Control Unit) development tool
“CRAMAS (Computer Aided Multi Analysis System)” real time simulator,
CORE-X aids in reducing time and development costs for motor control
ECU’s of hybrid vehicles and fuel battery-powered automobiles. Hereafter,
this product will be produced by special order.
Because of measures taken to lessen the harmful effects of automobiles
(exhaust gas, fuel consumption regulations) to the environment in
recent years, there is a growing trend to convert engines to electric
powered systems. Conversion of drive systems to electric drive in
hybrids and other vehicles involve large amounts of electric power,
and in their ECU development, evaluation by computer simulation
is becoming more and more important in avoiding the dangers of actual
test vehicles and having to build large scale facilities.
The real time simulator “CRAMAS,” a product which has been marketed
by FUJITSU TEN from the year 2000, has been well received since
its release for its capability to allow functional land performance
evaluations of control algorisms for engine control ECU and transmission
control ECU, as well as hybrid vehicle control ECU’s, under simulated
conditions identical to an actually installed condition.
In this developed motor board “CORE-X,” we installed a large capacity
FPGA (Field Programmable Gate Array) in order to enable faster,
high precision simulations. We have also integrated simulation processing
for inverters/permanent magnet synchronization motors/position sensors,
etc. into the FPGA, to create a unique motor model for enabling
ultra-high-speed processing. This allows reductions in both costs
and time for development and evaluation of algorisms and control
ECUs, for high speed, high precision control motors of hybrid vehicles
and fuel cell vehicles.
【Main features of the developed “CORE-X” motor board】
◆ 1μs simulation processing cycle (fastest in the industry)
◆ Variable settings during operation are enabled for parameters
of motor coefficients
◆ Equipped with Xilinx-manufactured Virtex II-Pro (built-in PowerPC405)
◆ Application also possible in motor control devices other than
for automobiles
