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."

Next Toyota Prius coming in 60-mpg 'Eco Grade' version?

There's some mystery surrounding the fuel economy level of the next-generation Toyota Prius. The closest we've had to an official number is 55 miles per gallon, which was hinted at by Toyota Motor Corporation's managing officer, Satoshi Ogiso, last year. That number wasn't an official target, but the company even provided a graphic (above) showing how each next generation Prius beat the previous one by four or five mpg. Since the current, third-gen model gets 50, well, we have been left to guess that 55 is the next logical target. But, according to a new report in Automotive News, the new, fourth-generation Prius that's due next year will come in two versions, with one having a bigger ego – sorry, eco – than the other. AN says that the model will arrive with a standard nickel-metal hydride battery pack in a version that gets "about 55 mpg" and then a new "eco grade" version with a li-ion battery that "will be rated at more than 60 mpg." AN says this information came from company executives who were speaking at an August meeting with Toyota dealers. Our sources within Toyota say that they haven't heard anything about two high-efficiency models, so we'll take this with the requisite grain of salt. The current version of the Prius Plug-In Hybrid does use lithium-ion batteries, but this is the non-plug model the dealers are talking about. We think. The dual-battery strategy is certainly a rumor we've heard before. We had thought that the li-ion pack would be for an extended EV range (the current Prius has a barely noticeable EV-only range), but such a pack would be lighter and could boost efficiency, too. In other words, we look forward to hearing more during the upcoming auto show season.

Automakers' sound systems: Crank it, don't yank it

Years ago, one of the first things most music lovers did after buying a new vehicle was drive to an aftermarket stereo shop to get the crappy stock components swapped for better gear. And you'd typically get not only better sound but also more bang (and boom) for your buck. But in the past decade or so, the overall quality of OEM audio has dramatically increased, while car electronics became more complex, removing the incentive for most new vehicle owners — and all but the most hardcore DIYer — to start from scratch. In 2010, I did a comparison of the average costs for OEM electronics vs. similar offerings from the aftermarket, and back then automakers' stock premium systems were by far the best bargain — and are probably an even better value now. The premium 14-speaker, 1,200-watt JBL system in the all-new 2019 Toyota Avalon is a prime example of this trend. It's standard on the top two Limited and Touring trims and is available as a $680 audio upgrade on the XLE and XSE. I doubt you can even buy 14 speakers and 1,200 watts of amplification from the aftermarket for 700 bucks, much less have it all installed. And because the system is bundled with Toyota's Entune infotainment system, Apple CarPlay and a surround-view camera, removing the head unit means you would likely lose these features. Another advantage of OEMs and their audio partners is they can design the car around the audio system. In the past, automakers would typically place speakers where convenient for packaging, not for optimal sound reproduction, and audio engineers were forced to compromise. But as with the Avalon's premium JBL audio system, this is starting to change. At a recent behind-the-scenes peek for media into the process of developing the system, Toyota and Harman engineers delved into the minutia of sealing the inner panel of the front doors to create an enclosure for 6x8-inch woofers, making space in the pillars for JBL horn tweeters and extensively measuring the acoustic properties of the interior to tune the sound to the space. I'm met some creative and skilled car stereo installers, but none with a degree in psychoacoustics. The system is also the first to feature Quantum Logic Surround that creates a multi-channel listening experience from two-channel sources. And it includes Harman's Clari-Fi processing that "rebuilds key details lost" in compressed audio formats used by streaming music services and MP3s.
