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."

2016 Lexus GS F First Drive [w/video]

Performance cars used to be about horsepower and chassis tuning. Lately the question isn't so much what's under the hood, but how many buttons are on the console. We're overwhelmed with individual settings for engine response, transmission, exhaust, steering, and ride. When did these cars turn into a choose your own tuning adventure? The Lexus GS F represents an attempt to step back from this over-adjustable madness and return to more bygone sports car values. It has a special engine, unique bodywork, and a chassis tuned for high performance. There are only two settings you need to play with. The first setting is the Drive Mode Select dial on the center console, which mainly controls the response of 5.0-liter V8 engine and the shift behavior of the eight-speed automatic. The engine is the same V8 found in the RC F, making the same 467 horsepower and 389 pound-feet of torque. New this year are small balancing weights on the crankshaft pulley that cut down on internal vibration. Drive Mode Select also changes the electronic power steering, air conditioning, and stability control (you can also turn it all the way off via a separate button). The engine is the same V8 found in the RC F, making the same 467 horsepower and 389 pound-feet of torque. You will use two settings in the GS F: Eco when you want to get somewhere, Sport S+ when you want to get somewhere fast. Normal and Sport S modes offer intermediate steps you don't really need. Eco mode softens the throttle and reduces the use of air conditioning for slightly better fuel economy. It also makes the center-mounted tachometer switch into an eco-driving gauge. S+ puts everything into sport mode, including a heavier steering weight and a higher stability control threshold. While Sport S mode shifts the noon position of the tachometer to just below the horsepower peak of 7,000 rpm, S+ goes a step further and turns the rev indicator into a solid bar that grows around the edge of the display. It also adds oil and coolant temperature to the readout. And how could we fail to mention G-Force Artificial Intelligence (or grin at such an overwrought name)? That's the shift logic the transmission uses in Sport S+. It's designed to hold revs in corners and downshift during hard braking. "Our goal with F is to make a driver's car, not a drag race winner." The other button in the Lexus GS F that you need to pay attention to is next to the Drive Mode Select knob, labeled TVD for Torque Vectoring Differential.

Toyota, Lexus will offer low-cost automated braking system

First, a technology gets better, then it gets a lot better, then it gets less expensive, then it gets a lot less expensive. Advanced driver safety and convenience systems are about to make that last step thanks to Toyota. Centered around a pre-collision braking system, there will be three suites of driver aids known as Toyota Safety Sense C (TSS C) for compact cars, Toyota Safety Sense P (TSS P) for midsized and premium cars, and Lexus Safety System+ (LSS+) for the luxury brand. TSS C pairs a camera with laser radar to provide a pre-collision system that prompts the driver to brake if it detects an impending accident, and can supply additional braking force and automatically brake between seven and fifty miles per hour. There are also Lane Departure Alert and Automatic High Beam. TSS P pairs a camera with more precise millimeter-wave radar. Starting with the three functions in TSS C, it adds pedestrian pre-collision capability and adaptive cruise control. This one will be available first, coming on the new RAV4 Hybrid and Avalon. TSS - either C or P - will expand to three more vehicles by the end of the year. The wallop is in the price: TSS C will be a $300 option, TSS P will cost $500. Compare the Ford Fusion SE, for instance - it's Driver Assistance Package comes with Lane Departure Warning, Automatic High Beams, it has Lane Keep Assist, Blind Spot and Cross Traffic Detection that neither TSS has, but doesn't have any autonomous braking feature. It costs $1,200, but requires you to add the Technology and Luxury Packages for a total price of $3,165. If you want Autonomous Cruise Control, that's another $995, for $4,160 in total. Instead of $300 or $500 on the Toyota. Lexus' LSS+ will come first on the new RX then spread to four more models by the end of this year, and cost between $500 and $635 to add as an option. It also uses a camera and millimeter-wave radar for its vehicle and pedestrian pre-collision system, lane departure warning and lane keep assist, automatic high beam, and auto cruise control. The similar package on a BMW X5, with no pedestrian component, is $1,200. Toyota says both safety suites will eventually be on "nearly all" of it products and all trim levels by the end of 2017.
