Automobiles have been developed for more than 100 years, from Europe at the beginning, to America, and now to Asia. In more than a hundred years, from the era of Karl Benz's three-wheeled internal combustion engine to the era of electrification in the 21st century, automobiles have defined automobiles from mechanical engineering to electronic controllers. Where does automobile development go from here?
In the past 10 years, the trend of electrification of automobiles has risen. Domestically-produced cars have lagged behind foreign technology for decades. Domestically-made cars want to overtake cars through the electrification tide. Can we really surpass the three giants of European, American and Japanese automobiles? As an industry veteran who has been in the automotive industry for 5-6 years, he expresses his own views on the software of domestic automotive electronic components.
At present, under the alliance of industry giants, a complete set of automotive cut-in open system framework has been jointly formulated: AUTOSAR (AUTomotive Open System Architecture). Under the trend of electrification in recent years, electronic and electrical components account for Nearly 50% of automobiles cannot be produced. Domestic OEMs have higher and higher requirements for parts and components. Parts manufacturers are required to be able to adopt AUTOSAR standards to realize software functions, but does AUTOSAR really promote the development of automotive electronic parts in the industry? ?
AUTOSAR's requirements for component manufacturers:
1. To establish the ability of AUTOSAR, which requires high personnel ability
2. The AUTOSARization of the code requires high resource requirements for the chip and increases the cost of the chip.
3. To establish an AUTOSAR system, component manufacturers need to purchase SIP packages from AUTOSAR suppliers. Small factories have no purchasing power, and a large number of small factories will be eliminated.
Advantages of AUTOSAR:
1. Unified electronic controller architecture
2. Standardize the software hierarchy and modularization of automotive controllers
3. Quickly build the controller software system
4. Standardized interface to achieve universal and high portability of modules
Disadvantages of AUTOSAR:
1. High development cost. AUTOSAR code packages and tools
