There was a time when sophisticated driver assist systems were the realm of luxury cars. The reason is simple, really. The cost of any new tech innovation is high, and it’s easiest to bury this cost in higher end vehicles offered at a premium price. It was thus with many innovations we now take for granted in our cars like air bags and anti-lock braking. These days, the most desired driver assist and advanced safety systems are pretty much standard fare in most new models.
We were impressed years ago when Honda launched its ‘Safety for Everyone’ program and made its latest safety innovations standard fare on all its vehicles. The auto industry as a whole has followed suit, and now even the most sophisticated systems can be found on entry-level models, increasingly as standard equipment or as available options. While drivers of premium vehicles may still be the first to experience the latest new twist operating silently behind the scenes as they drive, you can be assured the technology will filter down to all models over time.
There are reasons for that because safety is always on the minds of new car buyers. The availability of systems that keep drivers and their families safe on the road, or at least as safe as possible, are highly desired. Automakers know this. Active and passive safety offer a competitive advantage in new car sales, right alongside other traditional touchstones like value, style, dependability, efficiency, and performance. If a new and highly-desired feature is introduced by one brand’s vehicles, there’s no doubt you will be seeing it offered in competitive models soon enough. There’s too much at stake for automakers not to emphasize safety, just as they emphasize electrification, efficiency, and environmental performance in their new model vehicles.
These days, technology is an active participant in our driving experience, constantly looking to warn us of unsafe conditions and offer alerts, and sometimes even initiate last-minute control to avoid an imminent collision. Their importance can’t be overstated. In the early years of driver assist systems, there were claims and assumptions regarding their promise for preventing potential collisions and saving lives. Now there is actual data to support this.
Recently, GM partnered with the University of Michigan Transportation Research Institute to study the real-world effect its driver assist, active safety, and advanced headlight features were having in preventing or lessening various types of crashes. The study involved data from some 3.7 million GM vehicles across 20 models, making use of police crash report databases from 10 states. Comparisons were made involving vehicles equipped with advanced active safety features and others without this functionality.
The results showed that driver assist systems can make a dramatic difference in eliminating or mitigating crashes. Automatic emergency braking with forward collision alert was shown to reduce rear-end striking crashes by 46 percent. Lane keep assist with lane departure warning reduced lane departure crashes by 20 percent, with lane change alert and side blind zone alert bringing a reduction of 26 percent in lane change crashes.
Even advanced lighting made a difference in driving safety. Here, high-intensity discharge headlights brought a 21 percent reduction in nighttime crashes involving pedestrians, bicyclists, or animals. In addition, advanced headlight systems that automatically turn high beams on or off in response to surrounding conditions delivered a 35 percent reduction. When combined, the two lighting systems resulted in a 49 percent crash reduction.
Clearly, automobiles have become more complex over time. In their early years, an automobile’s electrical system was limited to fundamental functions like a starter, generator, headlights and taillights, instrumentation, and an audio system. Over the years this grew more extensive, including everything from navigation, electric-assist steering and braking, electronic transmission control, electronic ignition, anti-lock braking, an array of airbags, and advanced emissions controls.
Today’s more sophisticated automobile integrates all this and more, from active safety assist systems and real-time traffic navigation to semi-autonomous driving, all enabled by on-board computers. Industry experts point out that today’s vehicles are often equipped with hundreds of controllers and sensors, and dozens of on-board computers (electronic control units, or ECUs), generating tens of gigabytes of data every hour. It’s expected that the coming generation of fully autonomous vehicles could generate upwards of 30 terabytes every day.
Supporting the electronics that process, analyze, and activate, the array of cameras, radar, and LIDAR sensors strategically and discretely positioned around a connected car ‘see’ vehicles, objects, and people ahead, around, and behind. These feed information to on-board systems that enable everything from the view seen in a back-up camera to determining the speed of a car in front of you, allowing adaptive cruise control to adjust your speed to avoid overtaking the vehicle ahead.
These sensors are constantly evolving and improving, a necessity as we head toward fully-autonomous driving. While LIDAR continues to be a favored system by automakers, other innovations are in the works. One example is next-generation radar systems. Until now, vehicle radar has been limited to capturing just speed and direction, which is one of the reasons why vehicles use multiple sensor types for their driver assist and semi-autonomous driving features. Now, the newest long-range radar designs will determine an object’s speed, range, direction, and elevation, even at higher speeds and under challenging lighting or weather conditions.
Evolution is a hallmark of life, and it seems, of driving. Even as our cars are getting more complex in every sense as they adapt to modern life, they are also getting smarter…and safer. All that technology is delivering much more than the comfort, performance, entertainment, and driving pleasure we’ve come to expect from modern vehicles over time. We now benefit from a more confident driving experience and enhanced safety on the road as well, with technologies like those described below serving as our copilot.
ADAPTIVE CRUISE CONTROL: As a stand-alone system or as part of semi-autonomous driving systems, ACC works like conventional cruise control with the addition of sensing technology that determines the speed and distance of the car ahead. It modifies your set cruise speed to avoid overtaking that vehicle. Many systems can bring your vehicle to a full stop if needed. Some advanced systems even reference map data to anticipate upcoming curves, roundabouts, toll booths, and more, then automatically reduce speed accordingly.
AUTOMATIC EMERGENCY BRAKING: Coupled with advance warning of unsafe closing speed or other immediate hazards, this system will automatically apply emergency braking to help avoid or mitigate a collision. Rear and pedestrian AEB is also offered as part of this system.
AUTONOMOUS DRIVING: Sometimes confused with fully ‘self-driving’ capabilities not yet here or approved, to degrees, today’s semi-autonomous systems can help keep a vehicle centered in its lane, pace a vehicle ahead at a safe distance, and often bring your vehicle to a full stop in gridlocked traffic, then resume driving when traffic in your lane is moving again. Some systems identify the pressure of hands on the steering wheel to allow continuing use of a semi-autonomous driving system, while others, like Cadillac, use a strategically-mounted camera that monitors a driver to confirm they are paying attention to the road ahead.
BLIND SPOT MONITORING: This system alerts a driver of vehicles in its blind spots to increase safety when changing lanes, passing, or being passed.
FORWARD COLLISION WARNING: Audible and visual warnings are provided to alert a driver of the potential of a forward collision. Some systems also provide brake pulsing as a further warning to gain a driver’s immediate attention.
HEAD-UP DISPLAY: A HUD projects driving information projected ahead of a driver’s view, sometimes as simple as mph but often providing info on various driver assist functions including turn-by-turn navigation.
LANE DEPARTURE WARNING: This system provides audible and visual warnings if your vehicle strays outside of its lane when a turn signal is not activated.
LANE KEEP ASSIST: Taking over after a lane departure warning, this function provides varying degrees of steering input to help maintain lane position.
NIGHT VISION: Using infrared sensing technology, night vision displays an enhanced view of the road ahead that helps identify pedestrians, animals, or other hazards that may be beyond the view of a car’s headlights.
PARK ASSIST: This system enables a driver to select automated parallel, and sometimes perpendicular, parking functionality. It uses sensors to identify an open parking space of suitable size and the position of parked vehicles, then controls steering angle to automatically guide your vehicle into the space. Many systems require a driver to control braking, acceleration, and gear position, while others handle all functions automatically.
REAL-TIME TRAFFIC: Navigation systems that integrate real-time traffic information are valuable in saving time, fuel, and maximizing driving range with their ability to reroute around traffic jams and construction projects.
REAR BACK-UP CAMERA: Now found on a wide range of vehicles, a view to the rear is shown in a dashboard display or rear-view mirror when a driver shifts into reverse, often including grid lines depicting a driver’s angle of approach and relative distance from nearby vehicles or objects. Audible warnings are provided when objects are too close or a potential collision with an object, vehicle, or pedestrian is detected.
REAR PARK ASSIST: At low speed while in reverse, sensors detect objects and a potential collision, providing a warning brake pulse and then bringing your vehicle to a stop.
SURROUND VIEW CAMERA: This technology uses multiple cameras strategically positioned on a vehicle to provide a ‘birds’-eye’ perspective of the vehicle and its immediate surroundings.
Crossover SUV buyers looking to drive exclusively on electric power have a single choice today, and that’s Tesla’s Model X. Following in the footsteps of the Tesla Roadster and Tesla Model S, and ahead of the just-debuted Model 3, the Model X provides a unique driving experience for high-end buyers with its attractive design, advanced tech features, and zero-emission operation. While the model’s price tag means it’s not for everyone, Tesla fans will appreciate that the price of entry for the base Model X 75D has recently dropped by $3,000, to an MSRP of $79,500.
Beyond this full-size luxury crossover’s all-electric range of 238 to 289 miles, the model’s most distinctive features are its ‘falcon wing‘ doors and the largest panoramic windshield in production today. Model X doors articulate upward to enable easy access to second and third row seats, with the third row seats folding flush for more cargo capacity. The interior is designed to accommodate seven passengers with luggage carried in a front trunk or behind the seats. A recent $3,000 option enables both second and third row seats to fold flat to provide an expansive load floor.
Powering the Model X is an all-wheel drive system using two electric motors, one up front and another at the rear. The three models offered include the 75D, 100D, and P100D, with the number referring to their battery capacity in kilowatt-hours. The P in P100D stands for ‘Performance,’ with the $145,000 top version’s Ludicrous mode enabling acceleration from 0 to 60 mph in 2.9 seconds and a top speed of 155 mph.
Like Tesla’s Model S, the Model X uses AT&T to provide 3G and LTE Internet access to its onboard navigation and music services via Slacker. It also provides connectivity to the vehicle through Tesla’s iOS and the Android app, allowing remote adjustment of climate control settings along with other control features. Regular over-the-air updates add safety and navigation features, enhance performance, and improve the driving experience. Like other Teslas, the Model X can also be quick-charged at several hundred Supercharger locations along key transportation corridors in the U.S., which allows capturing an 80 percent charge in about 30 minutes.
Driver information is presented in a digital display in front of the steering wheel and a center-mounted, 17-inch touchscreen. Active safety technologies include side collision avoidance, parking sensors, and blind spot warning. Model X camera, radar, and sonar systems continually scan the surrounding roadway, providing the driver with real-time feedback to help avoid collisions. Model X is designed to automatically apply brakes in an emergency.
A sophisticated Autopilot system allows the Model X to match its speed to traffic conditions, stay within its lane, and steer around curves within a lane. It also enables automatically changing lanes with a tap of the turn signal. Our time behind the wheel of a Model X has shown Autopilot to provide a seamless, near-autonomous driving experience. For safety reasons and because this system is still 'learning,' Autopilot requires a driver's attention and hands are required on the steering wheel at set intervals. A ‘Summon’ feature allows the Model X to automatically park and unpark itself, plus open and close a garage door automatically. It can scan for parking spaces, alert a driver when one is available, and parallel park on command.
An available towing package with a high strength tow bar and two-inch hitch receiver allows the Model X to tow up to 5,000 pounds, although driving range will be diminished with the additional load. Software actively monitors trailer sway and applies braking as needed.
Tesla’s plug-in crossover aspirations don’t end with the Model X. In fact, the company has announced plans to produce the Model Y – a compact crossover – by 2020. The new model is expected to make use of much of the technology and architecture of the Model 3 and come at a more approachable price point than the Model X.
We are heading toward self-driving cars quicker than anyone could have imagined just a few years ago. While it will clearly be some time before our highways are packed with driverless cars making their way to work, home, and parts beyond, there are glimpses of the future driving alongside us now.
It may be the Honda Civic self-aligned in the fast lane beside you, or the Ford Fusion Energi in your rear view mirror that stopped without driver assistance as traffic ground to a halt, then automatically paced your car as your lane began moving again. Or maybe the driver of the nearby Subaru Crosstrek Hybrid who misjudged how quickly traffic would stop, but escaped incident because of on-board systems that sensed a collision and automatically initiated emergency braking. And what about that Tesla Model S ahead that signaled and changed lanes seemingly on its own as its driver focused on something else?
These are real capabilities of vehicles on the road today. Not all models with autonomous technologies are ‘green’ cars, but assuredly many of them will be since there’s a natural convergence of autonomous driving technology and more efficient cars unfolding before us. This is only gathering momentum as a growing number of vehicles begin to feature systems like these.
Already, cars are increasingly equipped with an array of sensors, radar, and cameras to facilitate driver assistance systems that help deal with mundane chores like backing up safely and parallel parking. These same sensors and systems provide a foundation for even more sophisticated autonomous driving capabilities.
Several automakers are striving mightily to lead the field. Tesla is one of these, not only with the ability for its Model S to autonomously stay in its lane and with traffic flow, but automatically and safely change lanes with the flick of a turn signal when Autosteer is engaged. Cadillac is another with its upcoming Super Cruise.
Volvo is also at the forefront of this race to an autonomous driving future, in part because autonomous cars are considered much safer ‘drivers’ than humans and this aligns well with Volvo’s ambitious goal to eliminate traffic fatalities in its vehicles by 2020. Its XC90 plug-in hybrid already features some of the most advanced autonomous systems out there including Sensus Connect, Intersection Auto Brake, and Pilot Assist. Volvo has also created its Concept 26 autonomous driving interior for the XC90, the first such autonomous-focused concept interior built on a vehicle platform sold today. Volvo is taking a lead role in the world’s first large-scale autonomous driving pilot project that will find 100 self-driving Volvos negotiating everyday driving tasks on 30 miles of public roads around Gothenburg, Sweden.
The specter of life with self-driving cars presents its challenges, not the least of which is consumer distrust of such systems and the concern we will lose the driving enjoyment and sense of freedom that automobiles have brought us since their invention. While we may be in a new era that finds technology impacting most facets of daily life – with this technology increasingly making its way to our cars – the love of driving remains a priority for many.
This is supported by a recent Volvo survey in which a vast majority of those asked said autonomous car technology should respect the love of driving and, in fact, autonomous cars should include a steering wheel even if they are capable of driving themselves. At the same time, most felt that technology in autonomous cars would make their travel time more productive. In other words, we want these worlds to coexist. There’s a lot to read into that …perhaps from the driver’s seat at 65 mph, no?
