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.

Lexus apologizes for anti-EV ad, Plug In America calls it 'outdated'

Anyone who's spent any time learning about the alternatives to the standard fossil fuel-burning internal combustion engine knows that there are arguments to be made for and against all of the main options. They also know that there is barely any refueling infrastructure for hydrogen fuel cell cars in the US, aside form a handful of H2 stations in California and one in South Carolina. Somehow, though Lexus, recently said there was an "established infrastructure" in 20 states in an online video ad on the company's official site. Another part of that site also made unfair negative comments about battery-powered electric vehicles, saying that it takes too long to charge the cars. Read our original post on the matter here. In the ongoing discussion about how the US moves away from inefficient gas and diesel engines, this was seen as a real muck up of the facts. Upon seeing the videos, pro-electric vehicle group Plug In America released a statement to AutoblogGreen (Lexus is owned by Toyota): Hey, Toyota, the 1990s called. They want their outdated anti-EV attack ad back. Plug-in electric vehicles charge while you're sleeping at home, far more convenient than making a trip to a gas station and coming away smelling like carcinogens. Driving on electricity costs about one fifth what it costs to drive the average gas car and about a third what it costs to drive the most efficient hybrid. An electric drive has smooth, instant acceleration which can't be matched by any gasoline engine. If you don't believe me, just ask anyone driving a Toyota RAV4 EV. The videos were produced by Team One, Lexus' ad agency. Exactly where the information came from and how it made it to the website is unclear, but Lexus spokesman Moe Durand said that Lexus apologizes for offending anyone and has taken the incorrect videos down. The company will review all the materials and alter and adjust the campaign as necessary, he said.
