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.

Google shares more details on self-driving car accidents

Google has pledged to release monthly reports on the status of its self-driving car program, and says these updates will include information on accidents involving the vehicles. But the company won't release the actual accident reports, a sore point for activists who recently have clamored for the company to be more transparent in the way it tests this promising technology on public roads. "Google is dribbling out bits of information in the hope to silence legitimate calls for full transparency," said John Simpson, privacy director for Consumer Watchdog, a nonprofit that has asked Google to release reports from the 12 accidents the company says it has been involved in over the past six years. "They are testing on public roads, and the public has a right to know exactly what happened when something goes wrong." Under California law, the accident reports are not considered public records. Google has attributed all accidents to human error, and says drivers of the other cars involved caused 11 of the 12 accidents. In eight of those, the Google cars were rear-ended, and the autonomous vehicles were sideswiped in two other crashes. One of the accidents occurred at an intersection when a human driver failed to yield at a stop sign, and in one incident, a Google driver accidentally rear-ended another car while manually driving. Google had previously provided those details. The first monthly report installment sheds new light on which types of self-driving vehicles were involved, directions of travel, locations, and whether the cars were operating in autonomous or manual mode. Update: Google says this information comes directly from the OL 316 forms used to report accidents involving autonomous cars in California, though it has "edited the summaries lightly to protect other drivers' information." But Google still will not release the original OL 316 forms, nor the "traffic collision report" forms used in California to report accidents. Another company that has been involved in a single self-driving car accident, Delphi Automotive, has released this information, which verified its car was not at fault. Regarding Google, Simpson said, "We now know a few more details of what happened. The problem is that it's Google's version and they want us to take their word for it." The Google self-report adds information that goes beyond accidents, with further details on the company's overall program.

Lexus lets enthusiasts build their own LFA to celebrate model's 10th birthday

Lexus launched production of the LFA, a limited-edition supercar still venerated in 2020, in December 2010. While fans would undoubtedly love to see a second-generation model to mark the occasion, the Japanese firm is celebrating 10 years of LFA production by releasing a paper model that enthusiasts can print and build at home. 500 units of the life-sized LFA were made by hand in Japan between 2010 and 2012. The paper model will be hand-made, too, but builders need to arm themselves with scissors and glue instead of wrenches, and production isn't limited. Anyone can print out the templates (which are included in our gallery) and put the car together. Lexus released four templates: one is blue, one is orange, one is white and one wears the colors of the Gazoo Racing team. Building each car is fairly straight-forward, and basic instructions are shown in our gallery. Lexus estimates assembly takes about an hour and a half, and it suggests folding the paper against a ruler to create a perfectly straight edge. It also notes builders should print out each template on A3 paper to make a bigger car. Full building instructions are published on the Lexus United Kingdom media site. Folks who make their own LFA at home are encouraged to share their creation by tagging the brand on its social media channels. We'll award bonus points to anyone that manages to make a paper version of the naturally-aspirated 4.8-liter V10 engine. As for a second-generation model, our advice is not to hold your breath. Lexus is focusing on other projects, like developing electric powertrains, and it doesn't sound like a follow-up to the LFA is high on the company's list of priorities. It hasn't been ruled out, however. "I love it, but we need your help. We need strong requests for a new LFA from the media. This can help us proceed," vice president Koji Sato told British magazine Autocar in 2019. Related Video:
