Toyota R&D shows off free piston engine linear generator for future EVs

We often hear how an electric vehicle powertrain architecture allows vehicle designers much more freedom than a traditional ICE powertrain does. With differently shaped battery modules and small electric motors, there are lots of way to put the pieces together. With today's plug-in hybrid technology, engineers still need to put a decent-sized ICE somewhere, but new technology from Toyota could free up the gas-electric vehicle designers of the future. Presented at the recent SAE World Congress in Detroit, the idea from Toyota Central R&D Labs Inc. and involves what is called a Free Piston Engine Linear Generator (FPEG). Think of it as a sort of one-cylinder, two-stroke mini-engine that can work either as a generator (thank to magnets and a linear coil) or to directly drive a vehicle. The current prototype is a 10-kW unit that Toyota say would provide enough power to get a B- or C-segment electric vehicle up to highway speeds (75 miles per hour) when paired up to offer 20 kW. Pairing the FPEGs is also important to minimize vibrations. One system tested by Toyota had a 42 percent thermal efficiency, but the engineers are working to improve the overall efficiency even further.

Local production could improve Toyota Prius' fortunes in China

The Toyota Prius is the world's most popular hybrid vehicle, but it may take domestic production capabilities for the model to achieve a high level of popularity in China. Japan-based Toyota is aiming to produce an increasing percentage of Prius components in China in order to bring down its price there, Bloomberg News reports. Eventually, the goal is to make all Priuses sold in China in that country in order to avoid the steep 25-percent import tariff. As it is, Toyota sold just 1,400 Prius vehicles in China last year, compared to about 234,000 in the US and 315,000 worldwide. Hindering sales is the fact that the Prius costs about as much as an entry-level Audi in China, where Volkswagen is the country's best-selling automaker. Toyota has been selling the Prius in China for almost a decade but may soon find local sources for the batteries and other hybrid parts for the Prius and Camry Hybrid, Bloomberg says, citing comment from Hiroji Onishi, Toyota's China chief, at the Beijing Auto Show. Part of the problem is that the Chinese government provides less than $500 worth of subsidies for each hybrid sold, compared to about $9,600 for an electric vehicle. While that subsidy may rise as China municipalities take on the country's growing pollution problems, there's lingering concern over spurring sales of a car that's made by competing Japan. Toyota starting making some of its Prius vehicles in China in 2005 but halted production on the second-generation version of the hybrid four years later.

US expands probe into ZF-TRW airbag failure-to-deploy to 12.3 million vehicles

DETROIT — U.S. auto safety regulators have expanded an investigation into malfunctioning airbag controls to include 12.3 million vehicles because the bags may not inflate in a crash. The problem could be responsible for as many as eight deaths. Vehicles made by Toyota, Honda, Kia, Hyundai, Mitsubishi and Fiat Chrysler from the 2010 through 2019 model years are included in the probe, which was revealed Tuesday in documents posted by the National Highway Traffic Safety Administration. It involves airbag control units made by ZF-TRW that were installed in the vehicles. The control units can fail in a crash, possibly because of unwanted electrical signals produced by the crash itself that can disable an air bag control circuit housed in the passenger compartment, according to NHTSA documents. The electrical signals can damage the control circuit, the documents say. ZF, a German auto parts maker which acquired TRW Automotive in 2015, said in a statement that it's committed to safety and is cooperating with NHTSA and automakers in the investigation. The case is another in a long list of problems with auto industry airbags, including faulty and potentially deadly Takata airbag inflators. At least 24 people have been killed worldwide and more than 200 injured by the inflators, which can explode with too much force and hurl dangerous shrapnel into the passenger cabin. The inflators touched off the largest series of automotive recalls in U.S. history involving with as many as 70 million inflators to be recalled by the end of next year. About 100 million inflators are to be recalled worldwide. On April 19, NHTSA upgraded the ZF-TRW probe from a preliminary evaluation to an engineering analysis, which is a step closer toward seeking recalls. So far, only Hyundai and Kia and Fiat Chrysler have issued recalls in the case. Four deaths that may have been caused by the problem were reported in Hyundai-Kia vehicles and three in Fiat Chrysler automobiles. NHTSA opened an investigation in March of 2017 involving the TRW parts in Hyundais and Kias. The upgrade came after investigators found two recent serious crashes involving 2018 and 2019 Toyota Corollas in which the airbags did not inflate. One person was killed. Jason Levine, executive director of the Center for Auto Safety, a nonprofit consumer group, said the ZF-TRW case shows the auto industry thus far has learned very little from Takata.
