The commercial value of the future of automotive intelligence is self-evident. In the process of intelligence, OTAs, as an important cloud technology in the iterative upgrading of automobiles, new energy vehicle manufacturers focus on research and development of technologies, are also trapped in the automotive OTA controversy, how can automotive OTAs better release value in the future?
Automotive OTAs are an inevitable trend
Model S first used a car OTA in 2012, which produced a certain subversiveness at that time, when Tesla could complete key card loopholes, increase mileage, increase top speed, and improve ride comfort through OTAs.
OTA is a kind of mobile communication through the air interface to achieve remote management of mobile terminal equipment and SIM card data technology, users can automatically download OTA upgrade packages through the network, automatic upgrade, so as to achieve the purpose of upgrade. Model S applies FOTA-Firmware OTA (firmware upgrade) and another SOFT-Firmware OTA (software upgrade).
As the name suggests, SOTA can only apply software updates to the vehicle layer, download the upgrade file from the cloud server to the vehicle through the wireless network, and upgrade the software, such as applications and map updates in the car screen.
FOTA is to upgrade the system layer of the vehicle controller, affecting the car's power system, battery management and other systems, you can download the ECU that controls a functional module of the vehicle, brush into a new firmware image online upgrade, such as the chassis, power, ADAS and other underlying systems for OS layer software updates.
At present, there are very few manufacturers with vehicle OTA upgrade technology, represented by Tesla, Ideal and Xiaopeng. Most car companies are gimmicks higher than substance, staying at the level of SOTA upgrades.
The pot OTA of the maker does not back
There is a process of technological development, and there is also a process of people's concept acceptance. New energy manufacturers should play a positive role in this, but WM, the ideal series of practices have caused new energy owners to question information safety, driving safety and driving experience.
Last year, Weima was deeply involved in the vortex of OTA upgrade locking. The so-called "lock power, manufacturers by re-setting the voltage range of the power battery to limit the upper limit of the battery charging and the total discharge of the power, to a certain extent, can reduce the probability of thermal runaway of the battery, reduce the incidence of spontaneous combustion accidents. The owner of the Wei carriage was "locked" without knowing the contents of the upgrade package, resulting in a shrinking endurance.
In addition, in response to the manufacturer's modification of the relevant legal information on the use of the vehicle, the owner of the wei carriage also added that "we may update or modify your vehicle system remotely without further notice to you or obtain your consent." Software updates or modifications may affect or even delete personal information stored in your vehicle's systems." The overlord clause once again aroused the dissatisfaction of the owners of the Wei carriage.
Coincidentally, there are ideal ONE car owners who reflect that when upgrading the OTA, they encounter the same overlord clause as the use of mobile phone software, only the option of consent, and are collected personal navigation, music playback history and other privacy data, and the various behaviors of the manufacturer lead to the dissatisfaction of the owner of the OTA upgrade.
Some car owners said that before using the OTA upgrade, the system did not inform the content and changes of the upgrade, after downloading the OTA upgrade package, the vehicle had a reduced mileage, slow charging speed, engine power is limited and so on.
So the car OTA itself has no shortcomings, the car OTA has certain problems in information security, can not avoid the danger of hacking, if the OTA data transmission process, there is a potential risk of being counterfeited, stolen, attacked, in the communication process will be malicious hackers hostage and tampered with, may lead to abnormal vehicle operation, privacy leakage, financial and even life safety threats. So users will worry about the security problems caused by the software if it is compromised.
Therefore, the policy regulatory upgrade is more conducive to the release of value by automotive OTAs and plays a crucial role. At present, the Ministry of Industry and Information Technology issued the "Opinions on Strengthening the Management of Intelligent And Connected Vehicle Manufacturers and Product Access", which stipulates that before enterprises implement online upgrade activities, they should file with the Ministry of Industry and Information Technology, and those involving changes in technical parameters such as safety, energy saving, environmental protection, and anti-theft should be declared to the Ministry of Industry and Information Technology in advance to ensure the consistency of automobile product production. In the future, there is a long way to go in terms of automotive OTA technology itself, policy regulation and user right to know.
