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."

2021 Lexus ES 250 AWD First Drive | Pick your first-world problem

ANN ARBOR, Mich. — Looking at the 2021 Lexus ES sedan, one couldnÂ’t be faulted for thinking it unchanged from the previous model year. There is a significant new element, however, with Lexus offering an all-wheel-drive ES for the first time. The ES 250 AWD is a bone tossed to customers living in the Snow Belt, many of whom find the confidence of all-wheel drive an easier investment than a set of snow tires for their front-drive vehicle. With our first drive of the new AWD model, weÂ’d have the opportunity to take it on a long trip to Northern Michigan and, as luck would have it, a terrific storm was headed our way complete with snow and bone-chilling temperatures. Aside from pushing lateral grip and balance to its limits on a race track — and, really, who tracks their ES? — it seemed the perfect opportunity to test the ES lineupÂ’s newest improvement. The new feature comes with a caveat, though, which could be a deal-breaker for fans of the ES 350Â’s 3.5-liter V6: All-wheel drive can only be had in the also-new-for-2021 ES 250 designation, which indicates the sedanÂ’s naturally aspirated, 2.5-liter four-cylinder engine. Unlike the I-4 in the ES 300h — ‘hÂ’ standing for ‘hybridÂ’ — the 250Â’s mill doesnÂ’t come linked to any electric motors. The engine and drivetrain go hand in hand. You can only get all-wheel drive with the I-4, and you can only get the non-hybrid four with all-wheel drive. Interestingly enough, the ES 250 AWD costs exactly as much as the V6-powered ES 350 in each of its trim levels. Both start at $41,025, and go up from there. If all that sounds familiar, perhaps it's because the mechanically related Toyota Avalon has the same price and drivetrain situation going on. It too is locked into the combinations of FWD/V6 and AWD/I-4, with equal price tags for both and for ultimately the same reason: the also-related Toyota Camry AWD. Because of the minuscule numbers the V6-powered Camry sells in, Toyota saw no need to invest in engineering the all-wheel-drive system to work with a V6. And since the lower-volume Avalon and Lexus ES are really only getting AWD because it can be essentially pulled off a shelf and plugged into the TNGA platform shared by all three, well, that's how you end up with this unusual ES 350 and ES 250 AWD situation.

Lexus RX gets Top Safety Pick award from IIHS

Lexus’ newly refreshed 2020 RX crossover has received a Top Safety Pick award from the Insurance Institute for Highway Safety. And as with many vehicles that pass IIHSÂ’s increasingly tough muster these days, thereÂ’s a caveat: It applies only to versions equipped with certain headlights. That metric was also what caused the RX to narrowly miss out on notching a Top Safety Pick+ designation, the highest possible. IIHS rated the base headlights and one of the premium headlight options — both static LED projectors — as acceptable, but it gave a poor rating to the available curve-adaptive LED headlamps, saying they created too much glare. Elsewhere, the RX aced crash testing, earning good ratings across the board. IIHS says this was the first time it put the luxury crossover through its passenger-side small overlap crash test, noting that Lexus made changes to the bumper and front-end structure to improve protection for front-seat passengers. It also gave a superior rating to the RXÂ’s vehicle-to-vehicle front crash prevention system, which avoided collisions in track tests at both 12 and 25 mph. Both the RX350 and 450h hybrid version received light refreshes for 2020, including the latest version of Lexus Safety System +. It includes new features such as daytime bicyclist detection and low-light pedestrian detection, adding to the existing pre-collision warning and adaptive cruise control. This is the fourth IIHS safety award for the brand in 2019, following Top Safety Pick+ awards for the ES, UX and NX.
