Toyota develops new pre-collision system with steering assist

A number of automakers are working on developing fully autonomous cars, but it looks like the groundwork for such technologies will likely show up first as semi-autonomous systems for both safety and convenience. Following recent announcements from Nissan and Ford in this area, Toyota has now released information for some of its advanced semi-autonomous technologies that could be offered in production cars over the next few years.
On the safety front, Toyota's new pre-collision system with pedestrian-avoidance steering assist is aimed at protecting the folks who aren't in the car. This system combines visual and audible alerts with automatic brake assist and automatic steering. If warnings don't get the driver to slow down, the brake assist kicks in if a collision is very likely, but if that is still not able to avoid the impending collision (and if there is enough room to do so), the car can automatically steer itself around the pedestrian. This sounds most beneficial for last-second dangers such as a person accidently stepping out into the road in front of a car. Toyota hopes to have this technology available to customers by 2015.
The Japanese automaker is also testing a suite of technologies called Automated Highway Driving Assist (AHDA). The key part of this is a new adaptive cruise control system that uses vehicle-to-vehicle (V2V) communications rather than a radar-based system. This cooperative-adaptive cruise control allows vehicles to communicate their acceleration and deceleration data with other cars, which Toyota says this helps to improve fuel efficiency and traffic flow. Also a part of AHDA is the Lane Trace Control feature, which sounds like a next-gen lane keep assist. This system uses cameras, radar and a computer to keep the vehicle in a "smooth driving line" by being able to change steering angle, engine torque and braking force. Toyota says this technology could be in place by the "mid-2010s."

2019 Lexus UX 250h First Drive Review | Flashy looks and smart hybrid tech

STOCKHOLM, Sweden — Lexus admittedly is late to the subcompact crossover segment, but it hopes to make up ground with the 2019 UX by offering an intriguing combination of hybrid technology and flashy design. Longer than any premium subcompact SUV rival at 177 inches, the UX's 60.6-inch height is lower than all but the Infiniti QX30 and Mercedes GLA, and it sits in the middle on width at 72.4 inches — the BMW X1 and Subaru XV are narrower, the Audi Q3 and Jaguar E-Pace wider. Those dimensions give the UX a much more hatchback/crossover feeling, rather than a boxy and upright SUV. The inline four-cylinder 2.0-liter gasoline engine teams with two electric motors to produce 175 horsepower channeled through an electronically controlled continuously variable transmission. The hybrid offers electric all-wheel drive with a dedicated electric motor generator integrated into the rear differential. Despite the crossover looks, Lexus never suggests the UX is a proper off-roader. On-road it does feel a little more solid, and promises more traction on slippery surfaces off-road. The U.S. market gets a strictly gasoline-fed option too, in the UX 200. It's powered by a 2.0-liter 169-horsepower four-cylinder engine paired to Toyota's new direct-shift CVT transmission and front-wheel-drive only. Economy figures are still to be finalized, but Lexus estimates 33 combined mpg for the UX 200, with the all-wheel-drive 250h expected to achieve 38 mpg combined. Related: 2019 UX is the most affordable Lexus In Europe, the UX will be sold alongside the now-aging CT hatchback, despite rumors the CT is on its way out (it's already been axed in the U.S.). But the UX is by far the superior vehicle. The CVT in the Lexus UX is better and doesn't whine like the transmission in older versions of the CT. The UX also handles way better, even though for most customers its environmental credentials, keen running costs and distinctive design are more likely to factor into the buying-decision process. The UX's cabin is a welcoming space. It's smart, logical and less cluttered than the larger NX. Material quality is excellent and original in places too — the optional dashboard covering akin to textured Japanese washi paper is a good example — and Lexus is stressing the brand's superior craftsmanship, called Takumi, throughout its range. Unfortunately, the interior is hamstrung by the laptop-style touchpad for the infotainment screen (7-inch is standard, 10.25-inch on F-Sport trim).

Lexus planning a hydrogen fuel-cell LS by 2017

Toyota's Fuel Cell System will certainly migrate to other vehicles in the carmaker's lineup, but Australian car site Motoring reports that one of the models at the head of the queue is the Lexus LS. According to its sources, the executive barge powered by hydrogen will be released by 2017 and take the top spot in the range, rolling in above the LS Hybrid. We're told that Toyota engineers will find a way to slide two hydrogen tanks into its bodywork with the same general setup as on the Mirai – one under the rear seats and another under the rear parcel shelf. The 150-kW fuel cell stack will be placed under the front seats. Motoring says the resulting sedan and its 220-kW electric motor would come in "at around 2,100 kg," which is 4,620 pounds; that's a ginormous 539 pounds less than the listed curb weight of the current LS Hybrid, and 387 pounds more than the standard LS. Assuming all goes as planned, it would have a range of roughly 238 miles, a few dozens less than the Mirai's range of about 300 miles. It would look slightly different, too, the front end getting larger intakes to cool the power unit. It wouldn't surprise us if Lexus does have a hydrogen LS planned – it would be a statement car, and the company likes making statements, even if few heed them; it has stuck with its LS 600h for the past seven years, yet of the 7,539 LS models sold through the end of November this year, only 61 of them were hybrids. The timing would be intriguing, however; by the time the LS hybrid came out, Lexus had already worked over its filet-and-potatoes models. And if the hydrogen version is going to come in above the $120,440 hybrid, well, that will be a statement indeed.
