Corporate History.
The company traces its origins to 1943, when was founded as a joint venture between the Toyota Motor Corporation and Kawasaki Aircraft Industries to produce aircraft engines for the Imperial Japanese Army Air Service. The company was quickly renamed after it was discovered that there was a pre-existing company with the same name.
After the war Tokai renamed itself , and shifted production from aircraft parts to sewing machines and automobile parts. In 1965 Aichi Kogyo merged with auto parts manufacturer Shinkawa Kogyo to form .
In October, 2019 Aisin Seiki announced they would merge with subsidiary Aisin AW, consolidating management and renaming the company. Effective April 1, 2021 the combined company was officially renamed "Aisin Corporation".
Aisin AW.
Aisin AW was Aisin Seiki's subsidiary building automatic transmissions. It was originally established in 1969 as "Aisin-Warner", a joint venture with BorgWarner. In 1981 BorgWarner reduced its equity in Aisin-Warner to 10%, and by 1987 had divested themselves of the remainder. Aisin-Warner was renamed Aisin AW in 1988, and merged with parent company Aisin Seiki in 2021.
It developed the Prius transmission and the world's first speaking navigation system.
Additionally, the two-axis Aisin AW hybrid design has been adapted to the 2016– Prius (excepting the Prius c), and has also been employed on "Gen 1" (2005-2007) and "Gen 2" (2008-2012) Ford Escape Hybrids (Aisin T-030 and T-031 eCVTs, respectively), both FWD and AWD models, with Ford providing the Atkinson Cycle engine, hybrid battery, and all software control systems, and with Ford developing the AWD functionality; and on 2017– Chrysler Pacifica Hybrid minivans (Aisin T-032 eCVT). The two-axis design eliminates the second planetary gearset ("motor speed reduction device") found in the 2010–2015 Prius and the Prius c, and which reduces the width and weight of the eCVT and improves its overall efficiency.
