Cars will be smart enough to save lives

Published

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.

Meet SAM

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.

LHI is coming to save your car from hazards

Local Hazard Information will give drivers advance warning of potential dangers lurking around the corner

Published

on

There are many times when knowing what is around the corner could be useful. But for drivers that knowledge could be critical. Now, thanks to Ford’s new connected car technology, it is also a reality.

Local Hazard Information (LHI) marks a significant step on the journey towards a connected transport infrastructure by helping drivers prepare for and potentially avoid dangers on the road. When drivers ahead encounter sudden tailbacks, accidents or spilled loads, the driver behind – and possibly out of sight – is given advance warning. This could also apply to everything from freak hailstorms, to sudden flooding, or even landslides.

The triggers for the system come from what is happening in the cars ahead. It could be that airbags have been activated, hazard warning lights are flashing, or windscreen wipers are in operation. Previous traffic incident alert systems have relied on drivers to input information in order to generate alerts. LHI works autonomously, without the need for any driver interaction, to generate information and issue warnings.

Hazards are only displayed – via the dashboard display – if the incident is likely to impact on the driver’s journey. LHI is designed to be more beneficial to drivers than hazard information from current radio broadcasting systems, which often deliver notifications not relevant to them.

Already featuring as standard and free of charge for the first year on the new Ford Puma, LHI technology is being rolled out across more than 80 per cent of Ford’s passenger vehicle line-up by the end of this year. Crucially, the benefit will not be limited only to those travelling in Ford vehicles. Information sent can be used to alert drivers of other manufacturers’ vehicles, and vice-versa.

“What makes Local Hazard Information different is that it is the cars that are connected – via the Internet of Things. There is no reliance on third party apps. This is a significant step forward. Warnings are specific, relevant and tailored to try to help improve your specific journey.” Joerg Beyer, executive director, Engineering, Ford of Europe

How it works

Sensors monitor activities including emergency braking, fog lights and traction control to detect adverse weather or road conditions. Data from these activities is then computed to determine the hazard location and whether a traffic incident has occurred.

The vehicle automatically provides updates through a secure connection to “the cloud” using the Ford Pass Connect modem. Ford’s technology partner HERE Technologies operates the central cloud-based platform that collates information from multiple vehicle brands, governed by a business-to-business agreement.

The more cars are connected to the network, the greater the efficiency of the system. When many vehicles generate the same warning, others in the vicinity receive incident information from the cloud via the cellular network, enabling drivers to reduce speed or take appropriate action.

Additional information is sourced from public authority incident databases and traffic reports to provide drivers with further advance warnings including approaching vehicles driving on the wrong side of the carriageway, animals or people in the road ahead, and roadworks.

The on-board modem will be connected at the time of vehicle delivery. Customers may choose to opt in/opt out of certain data sharing.

SA gets live EV charge map

Published

on

Drivers of fully electric and plug-in hybrid vehicles can now plan their journeys with ease using a live map to locate available public charging stations nationwide. 

The live map displays the entire network of Jaguar Powerway and GridCars supported public charging stations, and indicates the current status of each including if it’s online, offline or in use. The map also shows the time and date of the station’s last successful use, as well as a tally of that particular station’s total charge sessions to date.

Information about each charge station’s exact location with either map pin drops or GPS coordinates is also available.

Brian Hastie, Network Development Director, Jaguar Land Rover South Africa, says: “While the primary charging habit for the majority of EV drivers will be at home where it’s most convenient and cost-effective, we know that the future of electric mobility ultimately relies on a public charging network. As the rollout of public charging stations intensifies and the dots between existing locations are connected, it’s vital that EV drivers are able to view the status of chargers remotely. This live map makes that possible.”

Jaguar South Africa began the rollout of its Powerway network of public charging stations late in 2018. The Powerway includes public charging stations along frequently traveled holiday routes along the N1, N2 and N3, and at various points of convenience, such as shopping centres, in the country’s major hubs including Johannesburg, Pretoria, Durban, Cape Town, Port Elizabeth, East London and Bloemfontein. 

The Powerway network also includes publicly available chargers in customer parking areas at every Jaguar Land Rover retailer in South Africa. 

The majority of charging stations on the network are 60kWh fast chargers which also feature 22kWh AC fast charge ports to accommodate plug-in hybrid vehicles (PHEVs). The AC standard Type 2 socket will allow charging of all EVs currently available in South Africa, while the DC charger is fitted with the CCS DC type socket used by the vast majority of EVs in SA.

The R30-million Jaguar Powerway investment, combined with the network of GridCars-supported public chargers, makes day-to-day travel as well as longer day trips and even very long journeys possible for owners of electric vehicles.
