CRRC tested the world's first 12-meter pure electric intelligent driving bus with a maximum speed of 40 km/h in a straight line

That driverless car hasn't stopped yet, but this electric driverless bus has already arrived.
according toJinyang.comAccording to reports, today (July 18), after two months of closed testing, CRRC Electric Co., Ltd. independently developed an intelligent driving bus for public road testing in Zhuzhou, Hunan, and completed tests such as automatic cornering and automatic overtaking. According to the introduction, this model is a 12-meter-long pure electric bus that can accommodate 80 people. This is the first time that intelligent driving technology has been applied to this model in China.

Depending on the obstacles encountered in front, the bus will make corresponding judgments about overtaking or slowing down and stopping. If there is a moving vehicle ahead, the bus may choose to change lanes to overtake. If there is an emergency, Tang Guangdi, assistant general manager of CRRC Electric, told Jinyang.com that the smart driving bus will decelerate and brake accordingly according to the degree of emergency.

It is also different from ordinary buses. In the past, the dashboard became a digital display, and you could see data such as driving speed, roadblocks, and battery power.

The electric self-driving bus was tested for 5 kilometers, with a maximum speed of 40 kilometers/hour in a straight line and 15 kilometers/hour in turns.

Speaking of driverless buses, Yutong Bus took the lead in road testing in China two years ago. What Yutong tested was the smart bus iBus modified from the ZK6105 bus. Public information shows that the ZK6105 series bus is about 10 meters long. The total test mileage is 32.6 kilometers, from Zhengkai Avenue Urban Railway Jialuhe Station in Zhengzhou City to Kaiyuanmen Station in Kaifeng City. During the trip, it underwent tests such as lane changing and overtaking, and the top speed reached 68 kilometers per hour.

Using public information for comparison, CRRC’s electric smart driving buses may have slightly different sensor configurations than those tested by Yutong.

formerAccording to Jinyang.com, the car body is equipped with a total of 8 sensors, including cameras, lidar, millimeter wave radar, ultrasonic radar, high-precision combined inertial navigation, etc. The camera covers night vision cameras, which can theoretically realize intelligent driving during the day and night;Yutong IntelligentThe bus is equipped with 2 cameras, 4 lidars, 1 millimeter wave radar and an integrated navigation system.

In addition, the length of the vehicle will affect the difficulty of realizing intelligent driving, and the two are positively correlated. CRRC’s electric intelligent driving bus is 12 meters long, which is longer than the previous Yutong test vehicle.

YutongLatest new developmentsYes, it has launched a smart bus solution. It is reported that the solution realizes the integration of smart buses, smart operations, smart transportation, smart energy, etc. But it seems that it will take some time before the mass production of driverless buses is actually implemented.

Looking abroad, there are also some test cases for driverless buses.

Navya, which received 30 million pounds in financing last November, is a French developer of driverless electric buses. In January this year, the company launchedArma automatic busA two-week, eight-hour trial operation was conducted in Las Vegas, USA. No safety accidents occurred during the test, but the maximum speed limit was set at 19Km/h for safety reasons.

A friend from 36Kr experienced this automatic bus on site. According to her, the running speed is indeed slow. When encountering different obstacles, the bus can make its own judgment and deviate slightly from the original trajectory to dodge or stop slowly.

Arma automatic busAnother advantage is that you can call a bus through the mobile app. After getting on the bus, passengers enter their destination on the control panel, and the bus will calculate the optimal route by itself. This bus can carry up to 15 passengers and has a maximum speed of 45Km/h.

EasyMile, also a French company, also makes self-driving buses, andAlready commercially available. The self-driving bus EZ10 launched by EasyMile can carry up to 12 people, 6 people have seats and 6 people stand. It travels at a speed of 20km/h and reaches a maximum speed of 40km/h. Somewhat different from Arma's own determination of the optimal route, the EZ10 needs to set a GPS route before running. So far, EZ10 has been put into use in Finland and Switzerland. Last year EasyMile also partnered withJapan DeNA CorporationReached cooperation to trial operate EZ10 in Toyosa Park in Chiba City; in June this year,TaiwanThis bus was also introduced.

SingaporeThere are also trial operations of driverless buses, but this bus was modified by the Nanyang Technological University research team based on the Arma bus. It is equipped with 4 cameras and 8 laser radars, allowing it to monitor the surrounding environment 360 degrees. In addition, the car is also equipped with a GPS positioning system and a 3G communication system. At the same time, NTU has also reached an agreement with Singapore’s Land Transport Authority (LTA) to jointly develop driverless bus technology.

Looking at the situation at home and abroad, driverless passenger transportation is still in its infancy. It is more of a small-scale trial operation, so be careful when testing. Moreover, the capacity of passenger cars is still relatively limited, and the speed also needs to be improved.
