Months of mobile phone system update frequency is accustomed to, but the car system OTA is unusual? What is the purpose and meaning of automotive OTA, some people say this -
The source of OTA is divided into two types, one is extremism, that is, the function is continuously optimized to the extreme, which is a long-term investment; the other is to increase the function and require more "surprise effects", which will start from the attempt and then change from time to time.
The above view comes from The Automotive Engineer of Lando, after the first OTA of Lando FREE, combined with user experience and opinions, the R&D team understands the meaning of OTA in this way.
According to the statistics of Che Yun fungus, a total of 17 models have undergone OTA upgrades in the past two months, of which Lantu FREE is the most optimized function. It took two months from the first release of the OTA plan to the official launch of Lantu, and more than 60 functions were optimized, covering four major aspects: entertainment, interaction, experience and vision.
According to Lantu's OTA upgrade strategy, does Lantu FREE meet the user's expectations after the upgrade?
AI voice is the most discussed
After experiencing the voice interaction function of Lantu FREE on the spot, it was found that intelligent voice is like a bottomless hole, constantly probing, constantly experiencing problems, and constantly bursting demand.
Voice interaction is the most direct interactive means of automotive intelligence, and in-vehicle voice interaction is also an area that car companies continue to invest in research and development. This time, Lantu FREE has added a "visible can speak" voice assistant, as long as it is the content that appears on the screen, you can use voice dialogue. However, the experience of continuous dialogue function still has a caton phenomenon, it is reported that the voice assistant has a wake-up time of 20s, and it is necessary to shout out the wake-up words again after 20s. But engineers say they can talk to the voice assistant as long as they speak fast enough and have smooth semantic understanding. The reason why the current continuous dialogue is not sustainable is that the scope of semantic understanding is not large enough.
Lantu said that the semantic recognition is not accurate enough not only in Lantu FREE, which is also a problem for the entire industry, and the follow-up will follow the mainstream of the industry and continue to follow the optimization of AI technology. "At present, Lantu is jointly developed with partners in terms of voice and map, and with the third car entering development, Lantu is opening up the voice platform, and the access platform supports diversification, but the cloud is completed by Lantu itself." Zhang Guihai, head of the intelligent cockpit of Lantu Automobile, said.
In the process of experience, it was found that there are still some flaws in the upgraded voice interaction, such as the inability to wake up the voice assistant when opening the APP such as K song, the voice content cannot be customized, and the human tone and emotional color cannot be recognized.
Peng Shidi, head of functional development of Lantu Automobile, believes that the concepts of electric brands and technology companies incubated in traditional car companies are slightly different. Lantu is slightly conservative in the early planning of intelligent voice, and the primary concern is still driving safety. Driving-related voice commands are involved, and there is a possibility of danger due to misoperation. Therefore, the trend of transformation for automotive intelligence must be to meet personalized needs under the premise of safety.
For example, the sound source positioning of the voice cannot be 100% certain that it is the instruction issued by the main driver, so the degree of voice openness about driving safety will be reserved. When the technical limitations are broken, it can be clearly positioned as the voice of the main driver, and all the settings will be opened.
Compared with traditional car companies, many technology companies start from the Internet thinking, completely oriented to user needs, and pursue the ultimate experience of users. This is the difference in philosophy between the two.
Vehicle function update complete
The upgrades in the cockpit are more about entertainment functions and design experiences.
Lantu FREE provides a K-song stage in the car, users can enjoy the member song library tracks after logging in, and support double duet, using Danna audio, 10 speakers, and the second screen can also be connected to Bluetooth headphones to avoid affecting the main driver.
After the layout of the central control main screen media application of the car machine interface is adjusted, it is divided into different music types, which is clear at a glance. At the same time, the display music player is pinned to make it easier to open. In addition, the position of the card on the home page of the central control vice screen is also simplified to - music, film and television, radio, services, applications, etc., making it easier for the co-driver to operate.
The main and secondary screens have added some functional entrances: the main screen negative screen has added three energy mode switching functions of fuel priority, pure electricity priority and intelligent mode, added three kinds of seat comfort adjustment of ventilation, heating and massage, added convenient getting on/off, and convenient adjustment of the light and darkness of the sky. At the same time, the negative screen of the second screen has added three new seat comfort adjustments: ventilation, heating and massage.
In addition, there are some out-of-car feature upgrades.
The air suspension welcome logic is adjusted to the outside unlock, that is, from the current Bluetooth key into the welcome circle trigger, adjusted to the outside unlock trigger. When the user unlocks the vehicle, the vehicle suspension height is automatically reduced to the welcome height, and the minimum ground clearance is 125mm. At the same time, the suspension status icon has also been optimized, and when the suspension is not adjustable, it can also be fed back to the user.
The window closing scene is adjusted from away from the closed window to any form of closed window, and the situation of not being able to automatically close the window after leaving the car is closed is also optimized. In the latest OTA version of Ideal ONE, V3.0, the function of automatically closing the window of the locked car has also been added.
Remote control key opening tail door from long press adjustment to double-click, to avoid the key due to squeezing and the occurrence of false touch, but this function has a precedent, this time more like a few items; air conditioning temperature can retain the last set value; travel charging service optimization, in the car navigation map query nearby charging stations, will give priority to the list of free charging stations cooperated with Lantu, and also optimize the slow charging pile power failure and external discharge stop, need to pull the gun re-plug the situation; the user after parking to hang P gear, The machine automatically displays a prompt to open the fuel tank lid and the charging port cover.
In addition, Landu FREE has also added some new functions. Adaptive high beam speed reduction was introduced to low beam, adaptive adjustment of highway suspension, and the addition of "range extender mileage" and "vehicle health" sections.
Lantu said that the most direct source of demand for OTA upgrades is KOC and internal users, ranking first in the optimization items with the highest demand in the feedback. LanTu revealed that there are currently various needs, and its internal assessment will make a scheduling margin a quarter in advance.
Che Yun summary
Who should I listen to for OTA upgrades? There are a thousand Hamlets in the eyes of a thousand people, and the sense of experience and focus of personalized content varies from person to person. Through the OTA upgrade, the thinking of "software service optimization" and "user perspective" of new energy vehicle companies has changed, and the data dispute has also entered the OTA, and a large sample can be accumulated to give more perfect feedback.
At present, most of the functions of OTAs are still in the basic stage, and the show of car companies OTA has just begun.
