Toyota aims to build autonomous car around 2020 [w/videos]

The race is on to get increasingly sophisticated forms of autonomous driving technology on the road, and brands like Tesla are bringing these solutions to some drivers now. But as one of the world's largest automakers, it's no surprise to see Toyota competing in the field, as well. By 2020, the company thinks a person could be largely unnecessary for freeway trips. With a suite of tech called the Highway Teammate, a modified Lexus GS is already showing what's possible. Using a combination of millimeter wave radar, LIDAR, and cameras, the GS gets a full view of the road, and software processes all of the info to make decisions. The result is a ride on the freeway without human interaction. The system can merge, change lanes, make passes, take curves, and maintain a safe distance from other vehicles. Accurate map data is a necessity to make this work, so the system currently only being tested on Tokyo's Shuto Expressway. While Highway Teammate might not be the best name, it accurately communicates the way Toyota thinks of the tech. The company is making big investments in artificial intelligence to assist drivers, not completely replace them. You can see the system in action in the video below, and the second clip's gravely serious narrator explains the company's idea of having a fully connected road someday.

New Toyota Test Vehicle Paves the Way for Commercialization of Automated Highway Driving Technologies Toyota City, Japan, October 6, 2015-Toyota has been testing a new automated driving test vehicle called Highway Teammate, with the aim of launching related products by around 2020. In addition to demonstrating the capabilities of next-generation safety technologies, the vehicle represents Toyota's view of the evolving driver-car relationship in the age of artificial intelligence. Toyota believes that interactions between drivers and cars should mirror those between close friends who share a common purpose, sometimes watching over each other and sometimes helping each other out. Toyota refers to this approach as the Mobility Teammate Concept, and Highway Teammate represents an important first effort to give form to this concept.

Lexus RC F is a predatory sport coupe with a 450-horsepower beating heart

Take a look at that face. We can't be the only ones who see an automotive Predator staring back, right? Certainly, the Lexus RC F Coupe boasts a visually striking design that some are going to love and others are going to hate, but we can at least appreciate that it's aggressive, especially compared to the standard RC Coupe that we saw at the Tokyo Motor Show. And with good reason - there's a 5.0-liter V8 engine sitting under that massively domed hood with "more than 450 horsepower," along with a newly calibrated eight-speed automatic gearbox.
Interestingly, Lexus has tuned the RC F's engine to run on an Atkinson cycle under most circumstances, while it switches to the more typical Otto cycle when more power is required, presumably using some sort of advanced variable valve timing technology. Helping put that power to the ground with all those ponies wreaking havoc underhood is a torque vectoring differential, a first from Lexus.
Also involved in keeping the RC F planted is an aero package that includes wings and ducts galore. The headline bit is an active rear wing that deploys at 50 miles per hour and retracts back into the deck when the car drops back to 25 mph. A clear-coated carbon fiber roof can optionally join that carbon rear wing. There are apparently going to be three 19-inch wheel options, including the ones you see in our live image gallery above.

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."
