Toyota shows a smoother autonomous Lexus for CES

Toyota is bringing a new research vehicle to CES. The TRI-P4 autonomous driving test vehicle, based on the Lexus LS500h, is a major step ahead, according to Toyota, as it has improved computing power and additional cameras for better reaction times. Earlier test mules have also used the LS as a basis, and the shift to the new, fifth generation LS brings chassis and steering-control benefits, so the vehicle's movements are smoother in automated mode. The camera tech has also been better integrated into the vehicle design, courtesy of CALTY in Ann Arbor, Michigan. Development has been swift, as the TRI's P2.1 car was unveiled in 2017. The P4 car will be used for Toyota Research Institute's Guardian and Chauffeur mode development. The two tiers differ somewhat, as TRI's Ryan Eustice explains: "Our Chauffeur development is focused on full autonomy, where the human is essentially removed from the driving equation, either completely in all environments, or within a restricted driving domain. Guardian, on the other hand, is being designed to amplify human performance behind the wheel, not replace it. The introduction of the new P4 platform will help us accelerate the development of both tracks when it joins our fleet this spring." The vehicle's situational awareness is boosted by two extra cameras facing on the sides, and a new imaging sensor both forward and rearward. Toyota says the P4's lidar setup is a carryover from the previous platform, but that its machine learning is much improved by its more powerful computer setup. The electricity required by the P4's computing power also comes from the hybrid battery, and as the computer "brain" is now housed vertically against the rear seat's backing, actual trunk space has been freed. More LS500hs will begin to be modified into TRI-P4 vehicles during spring 2019. This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings.

Xcar gets Lexus LFA serviced at TMG

Toyota has made all manner of vehicles, from sedans and hatchbacks to crossovers and pickup trucks. It's even done a handful of sports cars over the years. But it's only ever done one real supercar, and that was the Lexus LFA. The ten-cylinder supercar was built at the dedicated, purpose-built LFA Works, a facility within Toyota City in Japan that's since moved on to making everything from bicycles to hydrogen fuel cell vehicles. But if you were lucky enough to be among the 500 customers to get your hands on an LFA, you may not be inclined to send it back to the factory every time it needs servicing. Especially not if you live in, say, Europe. That's why Toyota Motorsport GmbH was tasked with handling service for the LFA for Europe. The facility in Cologne, Germany, was once home to the automaker's F1 team, now runs its championship-winning endurance racing team and will soon again serve as the home base for its renewed assault on the World Rally Championship. So it's just the type of facility that could handle whatever comes up with Lexus' high-strung exotic, from servicing the V10 engine to repairing the carbon-fiber chassis if need be. After checking out the underground collection in its last episode, the guys at Xcar popped their heads in at the LFA service center. There they spoke with TMG VP Rob Leupen, who seems convinced that Toyota should make a new hybrid supercar. We hope he turns out to be right.

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."
