AutoBeta(AutoBeta.net)08/30 Report--

What is OTA? OTA's full name is Over The Air, which translates to aerial download technology, that is, the system can be updated online. Because the upgrade of OTA system can bring more good and comfortable experience to car owners. In the past, many traditional cars have to go to 4S stores to update the system, but now many new energy vehicles can be realized through OTA, which is both convenient and fast. It has long been popular on mobile phones, but it is a novelty in cars.

However, recently, a NIO owner revealed on the Internet that when he was driving, the vehicle had a system upgrade. He originally thought that the upgrade would be successful, so he upgraded the ES8 system through OTA. What is not, the vehicle system shows "update failed, driving is prohibited, please contact NIO Commissioner", that is, the vehicle can not be used, and then contacted after-sale. Unexpectedly, NIO sent engineers from Lanzhou 700 kilometers away to come to the rescue.

This triggered many netizens to comment, some netizens even said: "feel that NIO car owners have joined the product testing team."

Although the car's OTA upgrade is convenient and fast, and the frequent upgrade system can make the vehicle appear "more advanced", frankly speaking, as a means of transportation, there is really nothing that needs to be upgraded repeatedly in the future. Because the most basic driving and control parts should be calibrated when the car leaves the factory. And for the current car OTA upgrade is not mature.

Even Tesla, the most mature OTA technology in the electric vehicle industry, was previously exposed that after upgrading to the latest version through OTA, he found that he could not get into gear when using the vehicle. As a result, all the keys of the configuration were deleted, which dumbfounded the owner. This is equivalent to a car without keys, which is neither gearing nor locking.

And at the beginning of this year, the owner of a NIO car received a push from the vehicle update software while driving on Changan Street in Beijing, so she stopped and upgraded to P gear. As a result, the car parked on Changan Street for more than an hour, and the same vehicle could not be operated.

In fact, in today's OTA is not mature, trying to use mobile phone upgrade analogy car upgrade is not desirable. The mobile phone is an electronic product, the car is a means of transportation, the mobile phone crashes at most, the car crashes with the system on, and the safety of the passengers on board will also be threatened.
