Toyota develops new pre-collision system with steering assist

A number of automakers are working on developing fully autonomous cars, but it looks like the groundwork for such technologies will likely show up first as semi-autonomous systems for both safety and convenience. Following recent announcements from Nissan and Ford in this area, Toyota has now released information for some of its advanced semi-autonomous technologies that could be offered in production cars over the next few years.
On the safety front, Toyota's new pre-collision system with pedestrian-avoidance steering assist is aimed at protecting the folks who aren't in the car. This system combines visual and audible alerts with automatic brake assist and automatic steering. If warnings don't get the driver to slow down, the brake assist kicks in if a collision is very likely, but if that is still not able to avoid the impending collision (and if there is enough room to do so), the car can automatically steer itself around the pedestrian. This sounds most beneficial for last-second dangers such as a person accidently stepping out into the road in front of a car. Toyota hopes to have this technology available to customers by 2015.
The Japanese automaker is also testing a suite of technologies called Automated Highway Driving Assist (AHDA). The key part of this is a new adaptive cruise control system that uses vehicle-to-vehicle (V2V) communications rather than a radar-based system. This cooperative-adaptive cruise control allows vehicles to communicate their acceleration and deceleration data with other cars, which Toyota says this helps to improve fuel efficiency and traffic flow. Also a part of AHDA is the Lane Trace Control feature, which sounds like a next-gen lane keep assist. This system uses cameras, radar and a computer to keep the vehicle in a "smooth driving line" by being able to change steering angle, engine torque and braking force. Toyota says this technology could be in place by the "mid-2010s."

Growing demand could bring more body-on-frame off-roaders to the Lexus range

Car-based crossovers are outselling truck-derived SUVs by a wide margin, but Lexus still sees a strong demand for models that offer true off-road capability. It hinted that it could soon increase its presence in this segment. Toyota's luxury division entered 2021 with two body-on-frame SUVs in its range: the Land Cruiser-based LX (pictured) and the smaller, more affordable GX. Neither is a high-volume model, but both fared shockingly well in 2020. LX sales in the United States fell by 4.4% to 4,512 units, which is a great result in a year when double-digit declines were common, and GX sales increased by 9.9% to 28,519 units. Clearly, off-roaders are in demand. "What we have seen at Toyota is that there's so much of an appetite for [off-roading] that I see that [moving into] the Lexus brand as well. There is an appetite, a customer desire, a customer push to see all brands giving them more options. I think it would be silly for Lexus not to travel down that path," explained Jack Hollis, the head of automotive operations for Toyota's North American division, in an interview with Automotive News. He added that his team has identified a "white space" in the Lexus range that could be filled with an additional body-on-frame off-roader. He didn't reveal precisely what he has in mind, but there are a few possibilities we can rule out. We know Toyota is wrapping up the development of the next-generation Land Cruiser, even if the SUV might not be sold in America, and seeing a next-generation LX seems like a given, but we don't think that's what Hollis was referring to. Moving into the space above the LX with an even bigger truck is highly unlikely. Similarly, the idea of a Lexus-badged SUV aimed at the Jeep Wrangler and the Ford Bronco is neat but unrealistic. Ford's hotly-anticipated born-again off-roader has captured the attention of executives, however. "Holy cow! They sold out that thing, and I think there's a strong market out there for authentic off-road chops and credibility. We're seeing that with [the Toyota] 4Runner as well. I don't think it's any secret that [the 4Runner] is not all that new, but it continues to set records, and it continues to grow volume," pointed out Lexus brand head Andrew Gilleland in a separate interview with Automotive News. Could we see a Lexus-specific version of the 4Runner? We certainly wouldn't rule it out, especially because making an upmarket variant of the SUV would help Toyota leverage the benefits of economies of scale.

Jaguar solution to keyless start could save lives

UPDATED: An earlier version of this story indicated the Jaguar keyless start function was meant as a safety feature, when in fact, it is meant as a convenience one and will not work as described if automatic stop/start is not engaged. Today, The New York Times published an article about more than two dozen deaths related to drivers accidentally leaving their cars running, closing their garages and later succumbing to carbon monoxide that flooded their homes. The reason has been identified as "keyless start" features, or proximity entry and push-button start, where owners don't need to physically handle a key or fob to gain entry into the vehicle or start it. It is the latest, and deadliest, issue raised with this system after those related to security and simple inconvenience (for instance, leaving the car at a valet or car wash with the fob in your pocket). From my personal perspective, The New York Times had a rather harsh "evil carmakers" tone throughout the article. This is not a matter of a known faulty component, as with the GM ignition switch recall. This has as much to do with user error where people leave their car without pressing the "off" button and without noticing the engine is still running. About half of the cars in question are produced by Toyota and Lexus, brands that have offered keyless start longer than most. They are also brands with high rates of elderly owners, who seemingly made up a majority of reported deaths and injuries. One fire department in Florida even started a campaign alerting those in the area of the dangers of leaving your car running when it noticed a correlation between an increase in cars equipped with keyless start and calls related to carbon monoxide poisoning. I see several contributing issues at play, most of which go well beyond this particular issue. First is insufficient training of owners by dealers and/or owners not paying close enough attention during this training. Cars are complicated, but you should at least know how basic functions work. Second, woefully inadequate driver training in this country. Third, and with apologies to the AARP, insufficient testing of elderly drivers and/or insufficiently low standards for elderly drivers. If you don't know you have to shut the car off or cannot hear that an engine is running, perhaps you shouldn't be driving. Fourth, re-examining keyless start systems.
