Changan world record with self-driving 55-car parade

Changan has recently set a record for the largest parade of autonomous cars, according to Guinness World Records. A total of 55 vehicles were driven autonomously at the automaker’s test facility in Dianjiang, China on November 28, 2018.

The convoy of CS55 SUVs took nine minutes and seven seconds to complete the 3.2 km course, travelling at 30 km/h, with each vehicle leaving no more than a two-car gap. Certain changes were made to the cars’ systems, including improved sensors that better detect lane boundaries and the position of the car in front. The aforementioned two-car gap used was also narrower than when compared to normal road conditions.

This was achieved by reducing the cars’ systems’ event detection and response because of the controlled environment having fewer variables than public road conditions. The most important point in the preparatory stages was to detect risk factors in advance, said autonomous engineer Ren Chuanbing. These included field personnel walking the course, as well as the placement of photography equipment.

Initially 56 cars took part in the record attempt, with the final count confirmed as 55 because one driver ended up taking control during the parade course. “The drivers who participated in the test had no contact with the autopilot system at all, so we should also build up their confidence in our system in a short period of time to let go of the controls,” said Changan autonomous car engineer Yang Guo.

“The artificial intelligence and new energy of automobiles is a very important trend in the future development of automobiles. As the world’s first brand to break this record, we will make more efforts in the field of intelligence,” said the executive vice president of Changan automobile, Tan Benhong.

    The way it is presented, it sounds like drone cars rather than self driving with car having it’s own driving dynamics. All these car lining up in synchronous movement cannot be termed as self driving as they are following a single centralised programmed route.

    Autonomous cars are essentially drones. Electronic inputs from all the cars are shared by all autonomous vehicles in the same area. Therefore any deviation or input (eg breaking in the 32th car will be shared by all the cars, and those affected (33rd car onwards)will reacted instantly at the speed at which the signals are received.
    Imagine if all the cars talk to each other, eg at Junctions, their processors will talk to each other and decide which one to go first without compromising safety.

    Try cross junction la. Then we know safe or not.
