As the safety of motor vehicle is taken more and more seriously, the real-time events in the automotive electronics is more important. The control of engine and power train is the core of automotive electronics, and also the domain which demand the real-time quite seriously. This paper proposes a method which can decode the engine position signal. This method is under AUTOSAR frame, based on the MPC5554...
The dynamic, comfort and emission performances of vehicle directly dependent on the control of engine. Engine electronic control unit (ECU) receives the signals from the sensors, and gets the current engine status. Then depending on the signals, the ECU calculates fuel injection rate, injection timing and quantity. Accordingly the actuators which are driven by ECU carry out the better fuel control...
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...
AUTOSAR(AUTomotiveOpen System ARchitecture) is an open and standardized automotive software architecture, jointly developed by automobile manufacturers, suppliers and tool developers. The AUTOSAR standard will serve as a platform upon which future vehicle applications will be implemented and will also serve to minimize the current barriers between functional domains. To improve cost-efficiency and...
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...
The dynamic performance of the integrated system matched by the tire and the vehicle are the main factors for the driving performance of the vehicle. In order to improve the accuracy of simulation on driving performance of off-road vehicle and match correctly between the tire and the vehicle, the finite element method was used to establish model of radial tire and analysis the characteristics of tire...
With the energy shortage and environmental problems in modern society, many developed countries pay attention to the research on the electric vehicle which can realize the energy-saving. The electric machine is a key part of the electric vehicle. And the switched reluctance motor takes a lot of merits comparing to the other motor so that it becomes the preferred machine. The switched reluctance motor...
In order to solve the problem of short continuous driving mileage and long charging time of electric vehicle (EV), the method of auto and rapid exchange system of EV battery cases is proposed. The exchange system deals with corresponding control of multi-components which are relatively moving each other. Based on single chip wireless transceiver nRF905 and MC68HC908GZ16, the wireless communication...
