From September 14 onwards, Uber will launch a trial of driverless car service in Pittsburgh. A selected group of passengers will find that their own Uber software has an additional choice of driverless vehicles.
Uber announced the project as early as a year and a half ago, and employed dozens of researchers from Carnegie Mellon University (CMU) to work on the project's research and development.
On Tuesday, Uber disclosed to the media the Ford sedans that will be tested. These cars are equipped with radar, cameras, and other sensing devices. The test vehicle was placed at the Uber Advanced Technology Campus (ATC) located northeast of downtown Pittsburgh.
TechCrunch's reporter Signe Brewster was fortunate enough to be selected for the trial of driverless car service. Here is the sharing of her entire driving experience. Compile this article with the door to share with you.
The following is the text content:
Throughout the 45-minute drive, I gradually realized that this was just a research test and it was not the official release of the developed driverless vehicle. Uber hopes to test the performance of unmanned vehicles on the actual road from this trial, which can help the company improve technical defects. It also includes the interaction between the test vehicle and the passenger.
“We wanted to know what kind of reaction the driver sitting in the side would have and what the passengers in the back seat had about the software and hardware for the first driverless experience,†said Raffi Krikorian, director of the ATC.
| Driving ExperienceInitially, Uber's staff handed me a mobile phone and let me use the Uber software installed on the phone to call the car. One minute later, a Ford Fusion appeared and the Uber engineers sat in the front row of the car, so I took a seat in the back row.
After sitting down, I picked up the button on the tablet placed in the back of the car to remind the vehicle that everything was ready and ready to go. The scope of vision of the car will also be displayed on the flat panel. Blue represents the road and red represents the surrounding objects. Our drive began with the ATC, passing through downtown Pittsburgh, past the Ninth Street Bridge, and finally reaching the North Shore of Pittsburgh. Suddenly, this steel machine started on its own, as if it were controlled by a ghost.
The engineer sitting in the driver's seat is staring at the situation on the highway. His hand has been around the steering wheel, his feet have stayed on the brakes. When there is a car on the road that completely blocks the way, the engineer will turn the car into manual mode and change lanes manually. At present, Uber driverless technology has not yet developed this skill. Another engineer sitting in the co-pilot room holds a computer all the way to record the situation during the driving.
Shortly after departure, a reversing SUV suddenly appeared in front of the road. The first time we encountered an obstacle, my heart could not help but panic. When you are riding a manned vehicle, you never notice that there are so many accidents on the road. As we crossed the bridge, at the beginning, the car could not find the lane that it was driving. In the end, the lane we drove was blocked by a parked large truck. Engineers can only control humans and drive the car to another lane. At about the same time, a sanitation worker appeared in front of the truck and put a warning sign in the lane.
I do not know what kind of reaction will be made if a person or a warning sign is encountered on the road if the vehicle is in the automatic driving situation, but there are also many examples of automatic driving modes responding to the surrounding emergency situations during driving. . In the vehicle's autopilot mode, when the current bus stops on or off the passenger, or prepares for a right turn, it will stop behind. In addition, it can read the traffic light, but for the yellow light, it chose to stop waiting for one of them. It strictly abides by traffic rules, and everything in the driving process is almost the same as the normal driving experience, and even normal gradually becomes a little uninteresting. I was swept away at the start of the fluster.
Later, when preparing to start the return journey, the engineer asked me to get in the driving seat. When the indicator light turns blue, I just click on the silver button on the control panel and the car will start autopilot mode. Whether it is a brake, a gas pedal, or a red button, the car will return to the manual driving mode. When I found a truck in the middle of the road, I turned on the only manual driving mode.
When you sit in the driver's seat and pay close attention to the surrounding road conditions you don't need to do anything. This is a very peculiar experience.
It is easy for people to feel lazy, feel comfortable, and then start a divine journey. They may even unknowingly put their hands on their laps and move away from the steering wheel. I also finally understand why the boundaries between automatic parking and fully automatic driving are so blurred.
In the middle, I once again exchanged my position with the engineer and returned to the back seat. We took another round in the city. This time we passed the Strip, the most bustling area in Pittsburgh. There were cars all over the road. From time to time some trucks suddenly stop, and then someone will get off the bus to the roadside markets and restaurants. When we find that some vehicles are parked a bit outside, our car will automatically fine-tune the direction to the left. Under normal circumstances, it will simply go straight.
After we were seated, we encountered a traffic jam while crossing the bridge. In the process of slow movement, our car has been constantly starting and braking. It's as if people are driving in the traffic jam. Now, when I look at the Uber map again, we are already at our destination.
This time, Uber chose the Autopilot Test Vehicle as Ford's Fusions series, which is itself a very ordinary car. What is special is the additional row of sensors installed around the roof and body.
Judging from this driving experience, I trust this technology. Self-driving cars can identify obstacles, pedestrians, and even potholes on the road, and will respond intelligently accordingly. It was no surprise that the public had expected what they had before. The bigger challenge for Uber today is to plan unexpected surprises.
Uber will start an autonomous driving car service in parts of Pittsburgh. In a few weeks, the service will extend to the airport and the northern suburbs. The reason why the pace of development was unpleasant was that Uber needed to allow autonomous vehicles to receive maps in advance. This was a project that CMU thought the researcher Aaron Steinfeld was doing. Vehicles will receive and analyze a series of maps that contain important information such as speed limits during the development and testing phase. This will increase the ability of vehicles to automatically recognize various elements such as pedestrians in practical applications.
Uber recorded every road test and made full use of each data to improve the ability of self-driving vehicles to respond appropriately to specific situations. For example, vehicles will learn to wait at the crossroads and follow the order of arrival. However, if other normal vehicles do not follow the rules, then autopilot technology should also allow the vehicle to learn to avoid the first vehicle, as well as ignore the vehicles that stay too long.
Humans inevitably involve some potential social factors when driving. When the vehicles meet on the road, there will be eye contact between the drivers. The driver will also have subtle eye contact with the pedestrians who will cross the road so that they can understand each other's next actions. Although Uber's self-driving vehicles can also predict the possibility of pedestrians crossing the road to some extent, it is still a big goal to understand potential social factors .
In the next six months, Uber plans to arrange only one engineer to monitor the car. The ultimate goal is to completely replace the role of an engineer by a remote help center. When the vehicle encounters an unexperienced situation in the automatic driving mode, it will automatically contact the remote help center for human assistance. Uber is currently mainly investigating how vehicles respond to severe traffic jams and how to deal with excessive pedestrian traffic on the road.
