Electronic enthusiasts eight o'clock: Beijing time on August 10 morning news, according to Reuters, Tesla and the Nevada Motor Vehicle Administration (DMV) communication test for road test shows that the company is developing a Unmanned long-distance electric semi-trailers can be arranged into a formation to automatically follow the head car. The company is about to complete the development of the prototype.

At the same time, California DMV spokeswoman Jessica Gonzalez said California officials met with Tesla on Wednesday to discuss Tesla's plans for driverless trucks.

This series of communication and meeting shows that Tesla will apply its own driverless technology to the truck program, and is currently conducting field tests, which may be applied to the commercial transportation field that both Uber and Waymo have targeted.

After announcing the intention to produce heavy-duty electric trucks a year ago, Musk announced in April that he would release a semi-trailer in September and reiterated the plan at the shareholders meeting in June this year. But he never mentioned the driverless function.

Tesla has always been a leader in the driverless field and has applied the technology to its various models.

There are several Silicon Valley driverless technology developers who are looking at long-haul trucks. They believe that the technology has a clear prospect in this market, mainly because the long-distance trucks are relatively stable, with relatively little crossover traffic and allowing the driver to rest during transportation.

Some companies are also developing "team formation" technology to allow trucks to follow each other up close. If the vehicle behind this mode can follow the head car, the need for the driver can be reduced.

For example, Silicon Valley startup Peloton Technology is developing a "team formation" system with a number of truck manufacturers, including Volvo.

Tesla shares have risen nearly 70% this year. The stock fell 0.5% on the Nasdaq market to close at $363.53 on Tuesday, but the after-hours trading rose slightly.

Prototype test

The Tesla and Nevada DMV representatives agreed to meet on June 16th during the mailings between May and June this year. The Nevada Department of Transportation will also participate to discuss the testing of two prototype trucks in the state. .

“To ensure our consensus, our primary goal is to test our prototype truck formation and/or autonomous driving mode in a continuous manner without drivers, across state boundaries and within Nevada and California.” Nasser Zamani, head of Tesla's regulatory affairs, wrote in an email to Nevada's DMV official, April Sanborn. But he did not mention the specific test date.

No company currently tests unmanned trucks in Nevada without a driver. Zamani continued to send an email to Nevada DMV on July 10 to inquire about the terms of the test license.

California DMV spokesperson Gonzalez said Tesla asked to meet new employees on Wednesday and discuss the company's plans for driverless trucks. She said that the department did not understand the level of automation of the truck.

Tesla declined to comment, just let the reporter see the comments made by Musk before. Musk discussed the matter at the tweet and annual shareholders meeting.

Nevada officials confirmed that they had met with Tesla and said Tesla had not yet applied for a license. They declined to comment further.

Outside question

Musk once said that potential customers are eager to use Tesla's electric long-distance trucks, but their ability to deliver has been questioned.

Although existing truck companies and truck manufacturing startups have invested heavily in the electrification of local parcel delivery fleets, it is difficult to achieve nationwide long-distance transportation due to battery life limitations.

Venkat Viswannathan, a lithium-ion battery expert at Carnegie Mellon University, said electric long-distance trucks are not economically viable.

"Your truck will completely become a battery." Viswanasan said that a huge battery is needed to make the electric truck's endurance comparable to that of a long-distance diesel.

Scott Phillippi, head of UPS maintenance, engineering and internal operations, said the company's long-haul diesel trucks can run 500 miles (800 kilometers) per tank. In comparison, the company's electric parcel delivery trucks travel up to 80 miles on a single charge.
