This paper designs a kind of BLDC sensor less control system for vehicle fuel pump. The control system uses 78F9222 of NEC as a core control unit, and uses the Back-EMF method to achieve the sensor less control for BLDC. The system can implement over-current protection, over voltage protection and over temperature protection. Loading test shows that the control system has high performance to meet...
The Complex Device Driver is a loosely coupled container, where specific software implementations can be placed. The only requirement to the software parts is that the interface to the AUTOSAR system has to be implemented according to the AUTOSAR port and interface specifications. The purpose of the Complex Device Drivers is to fulfill the special functional and timing requirements for handling complex...
With the rapid growth of automotive electronics, the application requirements increase greatly, the hardware abounds continuously, as a result, software system becomes more and more complex. For this reason, some major OEMs found Automotive Open System Architecture (AUTOSAR), now including a large number of automotive, electronics, semiconductor and software companies. AUTOSAR's objectives are to...
