Toyota will bring Lexus-based Platform 3.0 autonomous vehicle to CES

The Toyota Research Institute says it will bring its next-generation Platform 3.0 automated driving vehicle to CES next week, an autonomous test car that is notable for incorporating the sensors and cameras into the body, rather than as ungainly attachments, and with the spinning LIDAR rooftop sensor replaced by a more sleek panel of sensors. Platform 3.0 is built on a Lexus LS600hL. Toyota Research Institute says it enlisted CALTY Design Research in Ann Arbor, Mich. and engineers at Toyota's nearby North America R&D center to conceal the equipment. As a result, Platform 3.0 gets a new rooftop weather and temperature proof panel, which it says was inspired by off-road motorcycle helmets, integrated into the available space in the sunroof compartment to minimize height. It's also embellished with chrome trim along the side, where it meets the roofline, and the rear swoops down to integrate with the LS's contour lines. The team also managed to consolidate computational electronics and wiring into a small box in the trunk. Toyota says the Platform 3.0 is one of the most perceptive autonomous test vehicles on the road today, with a design makes the test vehicle easy to build at scale. It gets a Luminar LIDAR system boasting a 200-meter, 360-degree range (the previous version only tracked the forward direction), enabled by four high-res LIDAR scanning heads that help it better see dark objects. Shorter-range LIDAR sensors feature low on all four sides of the vehicle, one on each front quarter panel and on the front and rear bumpers, to detect low-level and smaller objects, like children or road debris. Production begins this spring at the Toyota Motor North America R&D headquarters at low volumes to allow for flexibility, given the rapid rate of development of Toyota's autonomous test platforms. Some will be assembled using Toyota's Guardian dual-cockpit control layout to allow for transferring control between a human test driver and the automated system while keeping the driver as a backup, while the single-cockpit, fully autonomous Chauffeur mode will be shown at CES starting Jan. 9.Related Video: This content is hosted by a third party.

Lexus might introduce an all-electric successor to the CT hatchback

Despite sales of the Lexus CT hybrid hatchback ending last year in the U.S., Lexus isn't planning to abandon the hatchback segment in favor of the new compact crossover, the UX. The CT remains on sale in some countries, and Lexus's European boss is adamant the brand has to keep offering hatchbacks. Talking to the British AutoExpress, Lexus's Pascal Ruch says the CT has an important purpose, which is introducing new customers to the Lexus brand. Ruch told AutoExpress that the CT has a high "conquest ratio" of 70-75 percent, and that a CT customer is different from the envisioned UX customer. "I believe that all the segments we are now in, it's important to stay there," added Ruch. AutoExpress says the CT could be replaced in 2020 with a model that would be offered both as a hybrid and as all-electric, built on Toyota's new TNGA global platform. The hybrid is likely to be the 177-horsepower 2.0-liter unit seen in the new European Auris, which corresponds to the new U.S. market Corolla Hatchback. The CT's successor could be sold as both a conventional hatchback and a more crossover-like version, much like the new Ford Focus and its Active trim level; Ruch says Lexus is thinking through a new approach for the CT. The CT was introduced way back in 2011, selling some 15,000-17,000 examples per year in the U.S. until its first really weak year, 2016, which saw less than 9,000 cars sold. The following year, which proved to be its last model year in the United States, sales dropped under 4,700. In Europe, it's different for Lexus: The brand overall sells only some 45,000 cars per year, and the CT's steady sales of more than 8,000 cars per year are quite important for it.

8 things you should know about the Lexus LC 500h powertrain

Lexus unveiled the LC 500h today in The Netherlands, and I got to take a look inside its new hybrid system. On one hand it seems like a box of magic – it combines two seemingly incompatible transmission types into one package. But that's also the ingenious simplicity of the thing. We don't have all of the details on how it all works yet, but here's a rundown of the high points.Efficient business in front, low-key party in the back. What makes it all work is the mullet of transmissions. For the new hybrid transmission, Lexus used the Toyota Hybrid Synergy Drive/Lexus Hybrid System – which consists of an e-CVT with a planetary gearset and two electric motors (one for charging the battery, the other for motivation and regen) – and grafted a conventional four-speed automatic onto the back. The two units actually coexist in one package, with the e-CVT making things efficient and the automatic expanding the capabilities. So at the low end, the system can deliver more torque, and the engine can also run at lower rpm on the highway. It's all thanks to those fixed gear ratios, and it's surprisingly simple.Except it's not that simple. This is where the virtual gear ratios come in. Like current Lexus hybrids, the system has ratios it can call up with the e-CVT. In this case, there are six virtual ratios to complement the four real physical ratios, for a total of 10 "gears" at the transmission's disposal. (Not coincidentally, the V8 LC 500 coupe has a 10-speed automatic.) One of the four fixed gears is always engaged when the car is moving, so the 10 ratios come about from combinations of what the e-CVT in front and the automatic in the back are doing. In other words, all 10 ratios are variations on the four fixed gear ratios, which means that all 10 gears could be considered virtual.It won't use all the gears all the time. In Eco mode, the car will start off on electric power and skip the first couple of "gears." When it's set to Sport or Sport +, the engine will be engaged from a stop and the transmission will select the lowest ratio. The sportier modes will also ignore the top couple of gear ratios.It can drive faster with the engine off. In a Lexus GS 450h with the Lexus Hybrid System, for example, at speeds above 62 mph or so the engine has to start up. This is because something needs to take up some slack from the battery-charging motor-generator or else it will start spinning too quickly.
