Automotive OTA is one of the connected car services as a new technology to remotely update automotive software in wireless environment.
KONA MOBILITY is in possession of FOTA technology to reduce data traffic between OMA DM and wireless environment where OMA DM is the technology standard between automotive and update server as a core technology to update various software of automotive in wireless environment.
With generalization of the concept of connected car, there has been an increasing new request from drivers on the specifications for the convenience and the risk of hacking. With the distribution of remote software, there has been increasing needs for swift solution on various issues such as saving of costs in the field of automotive industry.
Global market investigating companies have expected that the proportion of full automotive parts will exceed 50% after 2020. Therefore, it is expected to be required to solve an issue of the recall related to S/W and explosively increasing problems of costs from them. At the same time, bug from automotive software or hacking will be directly related to the stability of passengers in the autonomous driving era. Therefore, automotive OTA technology is inevitable to maintain the up-to-date software for automotive through automotive OTA technology.
Therefore, KONA MOBILITY has been providing stable and reliable automotive OTA technologies to global automotive manufacturers and full part manufacturers with research and investment for multiple years.
System Architecture
Extracting differential data from DE (Differencing Engine) tool that operates in development PC or server, DM Server delivers differential data to the device through telecommunication network.
At this time, communication is made with DM Server through rules determining the DM Client that is installed in the device, and differential data delivered to the device are patched to original data through UA installed in the device while proceeding pre-determined update procedures.
FOTA (Firmware Over The Air)
FOTA is differential update technology to generate files by extracting only modified parts instead of downloading the entire firmware packet due to low bandwidth and high packet cost of telecommunications when modifying or upgrading F/W among OTA technologies while compressing and reducing the size of files before transmitting and updating them.
Use Case
IVI (In Vehicle Infotainment) Update
In the past, driver shall visit A/S center or download the software to USB memory or SD card and update them directly to the automotive when updating software of infotainment or map information of the automotive.
These procedures make drivers spend significant time with burden on the shoulder. Therefore, they are of an inconvenience to customers. Hereupon, automotive manufacturers are now able to provide convenient and safe update service to customers with background update or reservation update functions at any place from KONA MOBILITY OTA technology on their automotives.
ECU (Electronic Control Unit) Update
Automotives are equipped with about 30 to 70 controllers in general.
These controllers are equipped with software. Once bug occurs on such software with possibility of causing severe problems on the driving safety, recall or free repair is required for drivers. In such cases, manufacturers face a significant economic loss.
In addition, they need to have customers visit their business places receiving complaints from them that damage on the image of their brands and cause it to be devastated even further.
As these issues can be conveniently solved with OTA technology from KONA MOBILITY, it is available to provide high level of reliability to customers while resolving an issue of economic loss of automotive manufacturers but increasing loyalty to the brand.
In the upcoming autonomous driving era, such requests will become requirements instead of options.
Reference
KONA MOBILITY has developed automotive OTA technologies with global automotive manufacturers and automotive parts manufacturers in all over the world for multiple years through the development and verification procedures.
Automotives are required to stably receive large size data even while driving. Therefore, it is required for them to be ready for various issues such as battery drainage or errors in communication network along with the stability issues. Therefore, it has been difficult to easily update OTA on automotives so far.
Due to such difficulties, there are only a few companies in all over the world that are in possession of automotive OTA technologies. Under these circumstances, KONA MOBILITY has been acknowledged with technology power and stability by supplying technologies that can safely and swiftly update various types of software of automotives to global automotive manufacturers and automotive parts manufacturers.
