Based On Autosar Automotive Electronic Device Drivers And Abstract The Design And Implementation

In recent years, China’s automotive electronics industry is developing rapidly, butmainly in automotive affixation electronics, such as car navigation, reversing radar andso on. Backward abroad in this field due to the late start of the domestic automotiveelectronics industry and the field of automotive electronics control is for highreliability, security requirements, the technological level of the domestic automotiveelectronics industry can not meet the requirements of the requirements to control car’sdriving, and this kind of gap is growing continually.AUTOSAR (Automotive Open System Architecture) is the specification made byautomotive manufacturers, semiconductor manufacturers and software vendors in2003,due to its safe, reliable, configurable portability properties, and has gradually becomean international standard of the automotive electronics industry. BMW’s automotivewith AUTOSAR specification software launched; this is significant for AUTOSARspecification which has launched for almost10years. Although China has input somuch effort into automotive electronics industry, because of China’s automotiveelectronics industry’s research about AUTOSAR is still lagging behind the start offoreign, so as one of the automotive electronics industry, there’s a long way to go!The content of this thesis is mainly includes the following aspects:1）Firstly, analyses the automotive electronics control systems, considering thedemand of external devices’ safety, reliable and real-time from the automotiveelectronics, used the MISRA (The Motor Industry Software Reliability Association) tocode. MISRA specification is stricter and other specifications on coding, accordinglyavoid compiled execution code is inconsistent. At the end of the programming, checkthe code in accordance with the MISRA specification.2）Secondly, analyses the overall AUTOSAR specification, familiar with theAUTOSAR modules’ configuration during compile, link and run-time, and themodules’ coding specification. Learned to design the configurable, secure, and reliableproperties of AUTOSAR.3）With the characteristics of configurability, portability, after be familiar with the peripheral driver modules of the AUTOSAR specification, designed driver modulesof PORT, DIO, PWM, ICU and GPT external device. And after in-depth learning ofFreescale’s manual on MC9S12XEP100and DZ60platforms, implemented the driversin different chips by the development tools CodeWarrior. And according to the needs ofthe auto manufacturers, abstracted the driver of external device, designed andimplemented the I/O Hardware Abstraction Layer.4）Also according to the specific function of each external device, tested thefunction of all drivers. At last, tested the above modules referenced AUTOSARspecification in conformance, all passed the tests.
