Autonomous care are evolving at a rapid pace, but the question many are asking themselves is will they be able to handle unpredictable situations and keep their occupants safe? Nissan MD, MIKE WHITFIELD, sheds some light on the situation.
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.

Volvo to use blockchain to trace battery cobalt
Volvo Cars will become the first carmaker to implement global traceability of cobalt used in its batteries by applying blockchain technology. The announcement follows the reveal last month of the company’s first fully electric car, the XC40 Recharge.
Traceability of raw materials used in the production of lithium-ion batteries, such as cobalt, is one of the main sustainability challenges faced by carmakers. Volvo says its committed to full traceability, ensuring that customers can drive electrified Volvos knowing the material for the batteries has been sourced responsibly.
“It is a mineral that is essential to the production of the lithium-ion batteries that power electric cars,” says Greg Maruszewski, Managing Director of Volvo Cars South Africa. “But, sadly, it has long been suspected that some of the cobalt comes from mines that don’t use ethical mining practices. Now, thanks to blockchain traceability, we will know that the cobalt has been sourced responsibly. We are the first and only vehicle manufacturer that can make this statement. Accordingly, South African motorists who buy a Volvo in our XC90 T8 range can do so with pride – with the guaranteed knowledge that only ethical mining practices have taken place in the cobalt supply chain.”
Blockchain technology, which establishes a transparent and reliable shared data network, significantly boosts transparency of the raw material supply chain as the information about the material’s origin cannot be changed undetected.
Volvo Cars has now reached an agreement with its two global battery suppliers, CATL of China and LG Chem of South Korea, and leading global blockchain technology firms to implement traceability of cobalt starting this year.
Technology firms Circulor and Oracle operate the blockchain technology across CATL’s supply chain following a successful pilot earlier this summer, while the Responsible Sourcing Blockchain Network (RSBN), together with responsible sourcing specialists RCS Global and IBM, is rolling out the technology in LG Chem’s supply chain.
“We have always been committed to an ethical supply chain for our raw materials,” says Martina Buchhauser, head of procurement at Volvo Cars. “With blockchain technology we can take the next step towards ensuring full traceability of our supply chain and minimising any related risks, in close collaboration with our suppliers.”
A blockchain is a digital ledger containing a list of records linked to each other via cryptography. Within supply chains, the technology creates records of transactions, which cannot be changed while also enforcing a common set of rules for what data can be recorded. This allows participants to verify and audit transactions independently.
In this particular case, data in the blockchain include the cobalt’s origin, attributes such as weight and size, the chain of custody and information establishing that participants’ behavior is consistent with OECD supply chain guidelines. This approach helps create trust between participants along a supply chain.
Volvo Cars last month launched the XC40 Recharge, the first of an upcoming family of fully electric cars under the Recharge banner. By 2025, it expects half of its global sales to consist of fully electric cars, with the rest hybrids.
Last month, Volvo Cars also launched an ambitious climate plan, which includes a radical reduction of carbon emissions by 40% per vehicle by 2025, as well as a continued commitment to ethical business across its entire operations and supply chain.
CATL and LG Chem are renowned battery manufacturers, both with long and successful track records supplying lithium-ion batteries to the global automotive industry. They fulfil Volvo Cars’ strict sourcing guidelines in terms of technology leadership, responsible supply chains, reduction of carbon emissions and competitive cost models.
The agreements between Volvo Cars, CATL and LG Chem cover the supply of batteries over the coming decade for next-generation Volvo and Polestar models, including the XC40 Recharge.
Jaguar tech delivers wake-up call for drivers
From long working hours to daily school runs and the potentially stressful commute, Jaguar understands life for many is busier than ever. We’re so busy that 1 in 8 UK drivers admit to having fallen asleep at the wheel* – and this causes up to 25% of fatal accidents**.
As part of a wider vision to enrich and improve the lives of its drivers and passengers, Jaguar has developed a piece of technology, Driver Condition Monitor, which alerts the driver if it detects the tell-tale signs of drowsiness. The system takes inputs from thousands of data points, some of which are measured every thousandth of a second, including the Electronic Power Assisted Steering system, pedal inputs and general driving behaviour. Complex algorithms analyse all this to accurately determine whether a driver is becoming fatigued.
Fitted as standard on E-PACE and across the Jaguar range, Driver Condition Monitor detects if the driver is starting to feel drowsy and when required, provides an early warning to take a break. E-PACE’s instrument cluster displays a coffee-cup icon and sounds an alert when a prompt is needed.
Edmund King, Director of the AA Charitable Trust, said: “The statistics around drowsy drivers are shocking, even more so when you realise it is an under-reported issue. Any measure that helps reduce the risk of tired drivers, such as Jaguar’s Driver Condition Monitor, is to be welcomed. The only real cure for tiredness is to rest – if drivers feel tired, or are alerted to possible tiredness by their car, they should pull over at the next safe place, drink a caffeinated drink and take a short nap.”
David Willey, Assisted and Automated Driving Attributes Senior Manager, Jaguar, said: “At Jaguar, we continuously review the latest advances in vehicle safety and develop innovative technologies to improve the driving experience, making it safer and more enjoyable. Driver Condition Monitor, along with a range of Advanced Driver Assistance Systems (ADAS) are offered as standard across the Jaguar range.”
The Jaguar E-PACE is also fitted with an array of other advanced driver assistance systems to help keep the driver and occupants safe. Standard features on all Jaguar models include Automated Emergency Braking, Lane Keep Assist, Cruise Control with Speed Limiter, front and rear parking aid and a rear facing camera.
The Jaguar E-PACE’s unique combination of sporty looks, dynamic driving and innovative safety features mean it’s fun to drive and safe, too. The SUV you’ll never tire of, is priced from R684,400 in South Africa and can be configured at www.jaguar.co.za.
