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.

NHTSA expands new Takata probe to 4 more automakers

DETROIT — The U.S. government's highway safety agency has launched an investigation into four additional automakers that have a potentially deadly type of Takata air bag inflator in their vehicles but have yet to recall them. The National Highway Traffic Safety Administration said in documents posted Thursday that it is investigating Audi, Toyota, Honda and Mitsubishi in connection with a Takata recall involving 1.4 million inflators. This brings the total number of manufacturers potentially impacted to five, as BMW was connected to the issue when it was brought to light earlier in December. The inflators made by the now-bankrupt Takata have a distinct and separate problem that can cause them to blow apart a metal canister and spew shrapnel into people's faces and bodies. The problem killed a driver in Australia who was in an older 3-Series BMW, which has already recalled more than 116,000 vehicles. The problem is so dangerous that in some cases BMW has told drivers to park their vehicles until repairs can be made. The safety agency says in documents that Takata didn't provide details on the affected makes, models or model years of vehicles with the defective inflators. So it is telling the companies to recall them promptly. The agency says that based on when the faulty inflators were produced, it's likely that the vehicles to be recalled came from the 1995 through 2000 model years. In letters to all four automakers, NHTSA says they have five business days to notify the agency after finding out about a safety defect. “If your company has not yet gathered enough evidence to make a determination that the subject air bag inflators present an unreasonable risk to motor vehicle safety, reply with a detailed work plan including the benchmark dates required to make the determination,” the agency wrote in letters to all four automakers dated Wednesday. A Honda spokesman said Thursday it hasn't determined yet whether its vehicles are affected, but a decision should be made soon. Audi, Mitsubishi and Toyota said they are still investigating. NHTSA has told the companies to respond by Jan. 17. On Dec. 4, NHTSA posted documents from Takata and BMW detailing the problems. The documents said the Australian driver was killed, while another Australian driver and a driver in Cyprus were injured. Unlike previous recalls, the Takata non-azide inflators do not use volatile ammonium nitrate to fill the air bags in a crash.

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.
