What does ota mean?

The full name of Pacific Auto Network is "Over-The-Airtechnology", that is, over-the-air download technology, which realizes remote management of software through the interface of mobile communication. Traditionally, the software of the corresponding ECU is upgraded in the 4S shop through the OBD of the whole vehicle. OTA technology first appeared in Japan. At present, upgrading software through OTA is widely used in smart phones.

car OTA upgrade is just like the upgrade of computer windows system, and it can also be understood as the upgrade of mobile phone system. Every upgrade can improve, fix vulnerabilities or get more functions, performance or visual effects. This update is through online detection after networking, version matching, downloading new code to the local area, and then performing installation, verification and other procedures.

With the appearance of OTA, 4S stores are no longer necessary in the process of automobile upgrading, and the structure and process of the whole OTA are not complicated, which can be realized by generating update packages, transmitting update packages and installing updates.

both Tesla, many traditional car companies and even new energy car companies will pay more and more attention to OTA. Some are updates applied to maps, applications, infotainment systems, etc., and some have been extended to electronic control units. I believe that the future will also usher in a small peak of OTA.
