Toyota recalling 10k vehicles to fix wiper switches

Toyota has announced a voluntary recall covering approximately 10,000 cars in the United States. Affected models include the 2013-14 Camry and Camry Hybrid, 2013-14 Avalon and Avalon Hybrid, and the brand new 2014 Corolla.
The problem, as Toyota explains it, is that, "During manufacture of the wiper switch assembly in the involved vehicles, certain contacts on the switch terminal could have been manufactured incorrectly." This could lead to a short in the circuit when the wiper switch is moved between "off" and "mist," and thus, cause the windshield wipers to stop working. Not good.
Toyota will contact owners via first class mail, and the vehicles can be repaired at dealerships, free of charge. Have a look below for the automaker's official statement.

Toyota, Daimler Truck, Hino and Mitsubishi Fuso join forces

TOKYO — German truck maker Daimler, JapanÂ’s top automaker Toyota and two other automakers said Tuesday they will work together on new technologies, including using hydrogen fuel, to help fight climate change. The companies said Mitsubishi Fuso Truck and Bus Corp., whose top stakeholder is Daimler Truck, and Hino Motors, the truck maker in the Toyota group, will merge. Daimler Truck and Toyota Motor Corp. will equally invest in the holding company of the Mitsubishi-Hino merger, they said without giving a dollar amount for the deal. The companies plan to cooperate in reducing carbon emissions and developing other technologies such as autonomous driving, net-connected services and electric vehicles. “This collaboration among our four companies is a partnership for creating the future of commercial vehicles in Japan and the future of a ‘mobility society,Â’ said Toyota Motor Corp. Chief Executive Koji Sato. The two truck companies will work on commercial vehicle development, procurement and production to become globally competitive, the executives said. “We at Daimler Truck are very proud of our products, because trucks and buses keep the world moving. And soon they will even do so with zero emissions,” said Daimler Truck Chief Executive Martin Daum. “TodayÂ’s announcement is a crucial step in making that future work economically and in leading sustainable transportation.” Automakers are rushing to keep up with the global shift toward less polluting vehicles and to help in other ways to combat climate change. Commercial vehicles like trucks and buses are major contributors to auto emissions. In some cases rivals are joining forces to gain a a competitive edge and cut costs through “economies of scale” of by sharing knowledge and resources. “It is hard to go at it alone. Working together is crucial,” Sato said, Fuel cells power ToyotaÂ’s buses in Japan but its strength has been in hybrids, which have both electric motors like EVs and gasoline engines. Consumer acceptance of battery powered EVs has come faster than expected, Toyota officials say, and the company is hard at work on rolling out EVs in various markets. Details of the merger, including shareholding ratios, the company name and its structure will be worked out over the next 18 months, the companies said. They aim to sign a definitive agreement by early next year and close the transaction by the end of 2024. The deal still needs shareholdersÂ’ and regulatory approval.

Toyota finds 10% MPG improvement in hybrid PCU

Keeping up its from-all-angles approach to efficiency, Toyota has found yet another way to eke out up to ten percent more precious MPGs in its hybrid vehicles, this time electronically. The automaker has announced the development of new silicon carbide (SiC) power semiconductors for use in power control units, which it will begin testing on Japanese roads within the next year. The PCU using the silicon carbide compound offers less electrical resistance, which improves efficiency when passing current between the battery and electric motor. It also loses less power after shutting off, and can operate at a higher frequency. The net power loss of the new PCU is just one-tenth of the current silicone-only version (the latter accounting for 20 percent of total electrical power loss in today's hybrids). The result, so far, is a claimed five-percent improvement in fuel economy in test vehicles, with the potential of ten percent by the time the new SiC power semiconductor comes to market. Additionally, the carbide wafers allow for smaller a power module, coil and capacitor, thus allowing the entire PCU to be 80 percent smaller (see the side-by-side comparison in the accompanying photo, which you can click to enlarge). We've got a while to wait before we start to see the carbide technology to start making a real-world impact. Toyota aims to begin using the SiC units in 2020. By then, with improvements in the company's other key efficiency factors - engine technology and aerodynamics - cars like the Prius will likely see significant gains in fuel economy.

Toyota Develops 'Diamond-like' Computer Chips to Boost Hybrid Mileage May 20, 2014 Toyota City, Japan – Toyota is using one of the hardest materials in nature after diamonds to develop a semiconductor chip it hopes will improve the fuel efficiency of its hybrids, such as the Prius, by as much at 10 percent. The company and its partners announced today that they have developed a silicon carbide (SiC) power semiconductor for use in automotive power control units. Toyota plans to begin test-driving vehicles with the technology on public roads in Japan within a year. The chips, made from carbide - one of the hardest materials in nature, theoretically have superior characteristics such as one-tenth the electrical power loss and 10 times the drive frequency. Toyota said the chips would also allow it to reduce the size of current automotive power control units by 80 percent.
