Germany invented bicycle power assist device, bicycle into electric vehicle, weighing 200 grams for 60 kilometers

A German team developed a device that fits on a bicycle and powers the bike when you are tired. It is called a bicycle booster called adde, which turns the bike into electric in a short time. car. The power supply for this unit can be hung directly on the bicycle. It has four small parts, connected in series with the battery, and connected to the motor and rear wheel. With only the pedal pedal, the power unit can work immediately. In addition, its waterproof function is very powerful, even if it is raining, don't worry. The maximum cruising time is 60 kilometers and the maximum speed is 45 kilometers per hour.

The whole set weighs less than 200 grams. It uses a lithium battery to charge, and it only takes one hour to last for 50 kilometers, and it is easy to install and disassemble. (China Electric Vehicle Network)

Uber Chief Scientist: Unmanned driving has to wait a long time

Uber chief scientist Raquel Urtasun said on Monday that the company believes that large-scale applications of driverless cars will take a long time, but new technologies can save lives.

Ultason is the chief scientist of the Uber Advanced Technologies group, leading the department in Toronto. Later this year, Uber is ready to go public, and its driverless car division has attracted everyone's attention. In 2018, Uber lost $1.8 billion without taxes, depreciation and other expenses, and driverlessness increased losses.

Still, some people still believe that the transition to driverless success is crucial for Uber in the long run.

In 2017, Uber established Uber Advanced Technologies in Toronto and appointed Ultason as the director. Uber released a message last year that it will invest more bonuses in the Toronto department to expand the driverless business. The industry has long believed that Uber is a leader in the driverless world until last March when the Uber unmanned SUV crashed a pedestrian.

Subsequently, the Uber driverless car was withdrawn from the road. It also cut hundreds of test drivers and closed the Arizona business, where Uber built a driverless test center. In December last year, Uber resumed road testing.

Investors led by Softbank and Toyota are negotiating with Uber to invest $1 billion or more in the Uber driverless car division.

In the private equity market, Uber's valuation is as high as $76 billion, and it is preparing for an IPO with a valuation of up to $120 billion. People familiar with the matter said that Uber might launch an investor roadshow before the end of April. (Reuters)

GM, Ford and Toyota allied to promote the standard of driverless cars

GM, Ford and Toyota said on the 3rd that they are forming an alliance to help autopilots develop safety standards and help to develop relevant industry regulations in the United States.

GM, Ford and Toyota said in a joint statement that they will team up with the automotive engineering group SAE International Society of Automated Engineers to establish safety guidelines for self-driving vehicles to help set standards. The three will also collaborate to safely advance vehicle testing and competition. Development and deployment."

The new alliance, titled "Automated Vehicle Safety Consortium," will begin with a decision-making priority, with a focus on data sharing, interaction of vehicles with other road users, and safety testing guidelines. Randy Visintainer, chief technology officer at Ford Motor Company's Automated Vehicles Division, said that our goal is to work with companies and governments to “accelerate industry standards and pave the way for legislation.”

US regulators have been working hard to address the issue of how to supervise autonomous vehicles, while other countries are paying close attention to the implementation of emerging technologies. Last year, US legislators who were unable to agree on the way forward gave up legislation to speed up the road to unmanned vehicles, but this may be reopened later this year.

Last month, the National Highway Safety and Transportation Administration (NHTSA) asked the American public whether it should allow unmanned cars without steering wheels or brake pedals to be used as a reference for making laws. It is reported that the current NHTSA regulations prohibit unmanned vehicles from officially entering the road. (Reuters)
