摘　　要：采用电控增压控制技术可以实时精确地控制GDI汽油机增压压力的设定值,克服机械气动增压控制方案中的诸多弊端。论文利用ETAS公司的ASCET软件开发设计了增压控制模块、生成C代码并进行硬件仿真试验。试验结果验证了增压建模的正确性,并说明增压调节的闭环控制使发动机系统更加可靠稳定。The electric boost control technology can real -time and precisely control the set points of boost pressure for GDI gasoline, overcoming these pitfalls following the mechanical pneu- matic boost method. The software ASCET of ETAS Company is used to design the boost control mod- ule, generating C codes and carrying out the experiment of hardware simulation. The test results show that the boost modeling is correct and explains that the close -loop boost control enables the engine system more reliable and stable.
