As the autonomous car gets closer to becoming a reality, MIKE WHITFIELD, MD at Nissan South Africa, believes that they will also be smart enough to make life saving decisions without human intervention.
Autonomous driving technology is developing at a rapid pace. Business Insider publication’s research platform has forecast that there will be around 10 million cars with various self-driving features on the road in the UK by 2020. But the closer we get to our ultimate goal of completely driverless cars, the more critical it becomes for manufacturers to ensure it’s safe for us to place these vehicles on the road.
It’s no secret that autonomous driving technology has the ability to change lives and to save them. Not only is this technology expected to reduce serious traffic incidents – the Society of Motor Manufacturers and Traders (SMMT) predicted that in the UK accidents would reduce by 25 000 a year by 2030 – but it will also make automotive transportation available to people who were previously unable to drive.
But as advances in autonomous driving technology continue, so important questions around the complexity of having these vehicles on the road continue to arise. For example, how can drivers learn to trust autonomous vehicles? How will vehicles communicate with drivers and alert them to the presence of other vehicles on the road? And, what actions will vehicles take after identifying objects, signs and other road infrastructure such as painted lanes?
Can driverless cars handle unpredictable situations?
One of the biggest questions around the safety of this technology is what would happen in an unpredictable situation? Would the system make the right decision and navigate the vehicle through the scenario safely?
At the moment the autonomous driving technology used on roads is not fully autonomous. Nissan’s ProPILOT, still requires a driver to be present and ready to take over the control of the vehicle at any moment.
The technology, which launched and went on sale in Japan last year, enables cars to drive autonomously is a single lane, including in heavy stop-and-go-traffic. It’s the first time that a combination of steering, acceleration and braking has been operated in fully automatic mode, easing the workload of the driver in heavy traffic.
However, ultimate control and responsibility remains with the driver.
In fact, should the driver remove their hands from the steering wheel, a warning light will come on and an alarm will sound. The system will literally deactivate until the driver places their hands back on the wheel.
The day is fast approaching, though, when completely driverless cars will become a reality.
When that day comes, the question of who takes control in an emergency situation will need to be answered.
Particularly a situation in which the technology would be required to make an ethical decision. For example, the decision to swerve and avoid hitting a pedestrian might endanger the passengers within the vehicle. How does the technology discern the right course of action in this instance?
Not surprisingly, the inability of autonomous vehicles to ‘handle’ these unpredictable situations is one of the major stumbling blocks to a future of fully autonomous driving.
The good news, however, is that SAM has the ability to solve this problem. Nissan’s Seamless Autonomous Mobility system (SAM) can navigate unforeseen situations such as accidents, road construction and other obstacles. Ultimately, SAM will help us realise a future in which autonomous cars can operate safely and smoothly.
How does SAM work?
Basically, SAM is smart enough to know when not to navigate a potentially dangerous situation by itself.
Let’s say while driving you encounter an accident scene at which police are using hand signals to direct traffic, possibly against the normal rules of the road. In this scenario SAM will bring your vehicle to a safe stop and request help from the command centre.
This request is passed on to a mobility manager – an actual person who is using vehicle images and sensor data (streamed via the wireless network) to assess the situation, decide on the correct action, and create a safe path around the obstruction.
The mobility manager paints a virtual lane for the vehicle to drive itself through. Then once it clears the accident scene, the vehicle again resumes full autonomy.
The great thing about SAM is that it’s able to learn from experience – and as autonomous technology improves, vehicles will require less assistance from the mobility managers.
This technology will literally speed up the introduction of autonomous vehicles to our roads by decades.
Auto rivals team up for connected car demo
Rivals BMW, Ford and Groupe PSA, maker of Peugeot and Opel cars, have teamed up with the 5G Automotive Association (5GAA), Qualcomm Technologies and Savari for Europe’s first live demonstration of C-V2X direct communication technology operating across vehicles from multiple auto manufacturers.
The live demonstration also featured a live showcase of C-V2X direct communication technology operating between passenger cars, motorcycles, and roadside infrastructure. C-V2X is a global solution for vehicle-to-everything (V2X) communication in support of improved automotive safety, automated driving and traffic efficiency.
The demonstration exhibited the road safety and traffic efficiency benefits of using C-V2X for Vehicle-to-Vehicle (V2V) collision avoidance, as well as Vehicle-to-Infrastructure (V2I) connectivity to traffic signals and Traffic Management Centers (TMC). C-V2X was operated using real-time direct communications over ITS spectrum and demonstrated its ability to work without cellular network coverage, and underscores its commercial readiness for industry deployment as early as 2020. Superior performance and cost-effectiveness compared to other V2X technologies, along with forward-compatibility with 5G, make C-V2X direct communications a preferred solution for C-ITS applications.
Six demonstrations were shown including: Emergency Electronic Brake Light, Intersection Collision Warning, Across Traffic Turn Collision Risk Warning, Slow Vehicle Warning and Stationary Vehicle Warning, Signal Phase and Timing / Signal Violation Warning and Vulnerable Road User (pedestrian) Warning. The vehicles involved included two-wheel e-scooters provided by BMW Group, and automotive passenger vehicles provided by Ford, Groupe PSA, and BMW Group, all of which were equipped with C-V2X direct communication technology using the Qualcomm® 9150 C-V2X chipset solution. V2X software stack and application software, along with roadside infrastructure, were provided by industry leader, Savari.
C-V2X is globally supported by a broad automotive ecosystem, which includes the fast growing 5GAA organization. The 5GAA involves over 85 global members comprised of many leading automakers, Tier-1 suppliers, software developers, mobile operators, semiconductor companies, test equipment vendors, telecom suppliers, traffic signal suppliers and road operators.
Cellular modems will be key to the C-V2X deployment in vehicles to support telematics, eCall, connected infotainment and delivering useful driving/traffic/parking information. As C-V2X direct communication functionality is integrated into the cellular modem, C-V2X solutions are expected to be more cost-efficient and economical over competing technologies, and benefit from accelerated attach rates. C-V2X direct communication field validations are currently underway in Germany, France, Korea, China, Japan and the U.S.
C-V2X currently stands as the only V2X technology based on globally recognized 3rd Generation Partnership Project (3GPP) specifications, with ongoing evolution designed to offer forward compatibility with 5G. C-V2X also leverages and reuses the upper layer protocols defined by the automotive industry, including the European Telecommunications Standards Institute (ETSI) organization. C-V2X includes two complementary transmission modes:
- Direct communication as shown in this demonstration for V2V and V2I use cases
- V2N network communication, which leverages mobile operators for connectivity and delivers cloud-based services, including automated crash notification (ACN, as mandated by eCall), hazard warnings, weather conditions, green light optimal speed advisory (GLOSA), parking spot location, and remote tele-operation to support automated driving, to name a few.
“This demonstration builds on the successful C-V2X showcase we organised with our members Audi, Ford and Qualcomm in Washington DC in April, said Christoph Voigt, Chairman of 5GAA.
“We are excited to witness the growing momentum behind this life-saving technology and to see our members working together to deploy C-V2X, and to make it hit the road as soon as possible.”
“The BMW Group introduced the first C-ITS use cases already in 2013 with the market introduction of the BMW i3. Today most of envisaged C-ITS use-cases are already institutionalized. With the implementation of C-V2X, the BMW Group accomplishes the last set of the puzzle with a practical path to C-ITS showing quick benefits,” said Christoph Grote, Senior Vice President Electronics, BMW Group.
“With its ability to safely and securely connect vehicles, along with its evolution into 5G, C-V2X is integral to Ford’s vision for future transportation in which all cars and infrastructure talk to each other,” said Thomas Lukaszewicz, Manager Automated Driving, Ford of Europe. “We are very encouraged by preliminary test results in Europe and elsewhere which support our belief that C-V2X direct communications has superior V2X communication capabilities.”
“We’re moving forward with seamless communication between cars and their environment for enhancing road safety, as well as our customers’ safety,” said Carla Gohin, Group PSA’s Vice President for Research and Advanced Engineering. “Following the first European C-V2X direct communications demonstration we hosted with Qualcomm Technologies last March, we’re pleased to work with leading automotive and technology companies today to highlight that C-V2X interoperability is a reality.”
“This demonstration of interoperability between multiple automakers is not only another milestone achieved towards C-V2X deployment, but also further validates the commercial viability and global compatibility of C-V2X direct communications for connected vehicles,” said Enrico Salvatori, senior vice president & president, Qualcomm Europe and MEA. “We look forward in continuing to work alongside leaders in the automotive industry, like the 5GAA, BMW Group, Ford, Groupe PSA and Savari, to help advance the automotive industry’s shift towards a safer, connected and more autonomous future.”
“As one of the V2X pioneers, our company is extremely pleased to continue to help enable the next step in the V2X revolution that we helped start back in 2008,” said Ravi Puvvala, CEO of Savari. “For the last year and a half, the Savari team has worked diligently alongside the dedicated C-V2X engineers in the 5GAA partnership. The resulting string of increasingly impressive demonstrations is continuing to convince the world that C-V2X will soon be deployed around the world.”
Fleet management in 360
An on-board dual camera system from global fleet management vehicle recovery and insurance telematics provider, Cartrack, reduces the costs of managing vehicle fleets, while creating new ways to motivate drivers and improve their on-the-road performance.
Historically, commercial drivers within fleets have been far removed from active management and oversight, with limited tools available in helping fleet owners understand how their drivers actually behave on the road. This lack of visual tracking ability has seen fleet managers struggle to achieve meaningful driver skills development, while also leaving companies vulnerable to poor operational performance and financial losses resulting from accidents.
Cartrack’s Drive Vision system is dramatically changing this status quo.
Drive Vision is an on-board dual camera system that records video footage with a 120-degree exterior view of the road ahead, and a 160-degree view inside the vehicle cab. Not only can fleet managers actively monitor all the footage that they wish, the system also records specific events such as speeding, harsh braking or an unforeseen action from a third-party.
Drive Vision’s video is continuously captured and then made available to users in two ways. The footage is either buffered in the unit’s memory card for up to five days, and selected time slots can be downloaded by the user via a web interface. Alternatively, footage is also automatically downloaded to the system when specific events occur, such as speeding or a collision. The captured footage is stored at a web address and is immediately accessible to the client at any time. In addition, the data centre’s driver exception reporting mechanism can review the footage against a client’s pre-determined driver behaviour stipulations, creating a balanced and flexible driver performance assessment tool.
Cartrack CEO, Andre Ittmann, notes why Drive Vision is so useful for companies.
“There are two key strategic benefits to the technology. Firstly, the company has a clear visual record of events in the case of an accident or legal dispute. Achieving this kind of detailed view hasn’t been possible before, and it can dramatically reduce the costs around incidents and accidents, on an ongoing basis. Secondly, Drive Vision is a highly functional, event-based coaching system. It therefore allows fleet managers to develop a culture that rewards excellent or improved performance, while also giving them the power to actively close skills gaps. “
Ittmann also notes that fleet video footage allows the company to monitor and manage aspects of its service and market performance, including the driver’s ability to access a work site, thereby ensuring timeous arrivals at designated locations and the ability to oversee passenger count and conduct.
Ittmann concludes that Drive Vision offers untold long-term advantages for companies.
“Beyond simply gaining a more efficient means to discipline errant drivers, Drive Vision also empowers fleet managers to proactively implement measures that will result in long-term benefits for their company. Ultimately, the company can also reduce costs related to driver mismanagement while simultaneously improving a driver’s skills and their performance on the road.”
