Toyota reveals latest autonomous tech test bed

Toyota revealed its latest autonomous technology effort Friday, a sophisticated Lexus LS 600hL prototype that showcases its plans to advance in the emerging field. The Lexus is the first developed entirely by the company's in-house Toyota Research Institute and it will focus on the car's ability to learn and see behavior on the road. Toyota is showing the car at the Prius Challenge event at Sonoma Raceway. The Lexus uses Lidar, radar, and sensors, which potentially reduce reliance on mapping. The prototype advances Toyota's last concept vehicle shown at the Consumer Electronics Show in 2013. This one is said to be more flexible and it will focus on Toyota's two autonomous tech pillars, called Guardian and Chauffeur. Guardian is meant to improve safety features, while Chauffeur moves toward full autonomy. "We believe Guardian can probably be deployed sooner and more widely than Chauffeur, providing high-level driver-assist features capable of helping mitigate collisions and save lives, sooner rather than later," Toyota Research Institute Gill Pratt said in a statement.

Toyota Land Cruiser vs Lexus LX 570 Suspension Flex Test

There’s no need to explain the Toyota Land Cruiser, one of ToyotaÂ’s earliest successful products. The 2020 Toyota Land Cruiser Heritage Edition celebrates some 60 years of popularity of a vehicle that has survived the segmentÂ’s “mall wagon” phase and the rise of crossovers. Its already-sterling reputation has received an additional recent push from the rise of overlanding — an outdoor pastime that has always existed but only recently got a press agent. By comparison, the Lexus LX is a more recent development. Debuting in 1996, the LX 450 was little more than an 80-series Land Cruiser with cladding, a Lexus badge and a higher price. The amount of styling differentiation and luxury specialization has increased over the years to the point that the newest LX 570 actually seems like a completely different vehicle. In truth, the 2020 Lexus LX 570 and the 2020 Toyota Land Cruiser are both 200-series Land Cruisers under the skin. They share the same thirsty 5.7-liter V8 engine and the same frame that features a double-wishbone suspension at the front, a five-link coil spring suspension at the rear and a 112.2-inch wheelbase in the middle. The styling is strikingly different, of course, but so are the hidden details of their suspensions. The Land Cruiser employs a simple set of coil springs and shock absorbers, but with an interconnected pair of automatically disconnecting stabilizer bars called KDSS (Kinetic Dynamic Suspension System). The Lexus, on the other hand, has fixed stabilizer bars and coil springs, but its “shocks” are really hydraulic cylinders that perform height adjustments and transmit suspension movements via piping to remote electronically-adjustable damper valves mounted along the frame rails. All of the above begs a question: Which of them will go farther up my RTI ramp and, by extension, offer better suspension articulation in an authentic off-road situation? Right away, the very approach to the ramp demonstrates a huge difference and a serious issue for the LX. Its normal cruising height (there is a lower height, but this isnÂ’t that) doesnÂ’t provide enough approach clearance to attempt the ramp. The front spoiler contacts the nasty grating before the tire does. ItÂ’s a close-run thing, but from this point on, clearance gets SMALLER as the left front suspension compresses on the way up. If it's touching now, itÂ’s only going to get worse if I go forward.

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.
