The move includes patents awarded during more than 20 years of hybrid electric vehicle technology development as well as some pending applications for the latest technologies Toyota are working on.
As a second measure, Toyota will offer to provide fee-based technical support to other manufacturers developing and selling electrified vehicles when they use their motors, batteries, power and electronic control units, and other vehicle electrification system technologies as part of their powertrain systems.
At face value, offering some of their secrets to potential competitors in the car industry might seem like an unusual move.
However, by granting royalty-free patents and providing technical support on Toyota vehicle electrification systems, they hope to further promote the widespread use of electrified vehicles. In so doing, they hope to help governments, automakers and society at large accomplish goals related to climate change.
Toyota has their own Environmental Challenge 2050, a set of long-term action targets for sustainability, aiming to reduce CO2 emissions from vehicles and plants.
The royalty-free patents are advanced technologies found in electrified vehicles, particularly those used in hybrid electric vehicles (HEV) that have helped Toyota realise enhanced performance, reduced size, and cost reductions.
More specifically, the patents included are for parts and systems, such as electric motors, power control units (PCU – as shown below), and system controls. These are core technologies that can be applied to the development of various types of electrified vehicles including HEVs, plug-in hybrid electric vehicles (PHEV), and fuel cell electric vehicles (FCEV).
The grant period starts immediately and lasts through to the end of 2030. Toyota has already been offering 5,680 patents related to its FCEVs since January 2015.
Now, Toyota is adding approximately 2,590 patents related to electric motors, 2,020 patents related to PCUs, 7,550 patents related to system controls, 1,320 engine transaxle patents, 2,200 charger patents, and 2,380 fuel cell patents (bringing the total fuel cell related patents to 8,060).
Toyota are aware that considerable time, money and resources are required to develop sustainable mobility to help combat rising emissions. Toyota receives a high volume of inquiries about its vehicle electrification systems from companies that recognise a need to popularise hybrid and other electrified vehicle technologies.
With that in mind, car manufacturers will be offered overviews of Toyota’s vehicle electrification systems, control guides, and detailed explanations of tuning guides for vehicles that will utilise its systems.
The guidance that Toyota will provide, for example, includes helping other car-makers to achieve high-level product performance in terms of fuel efficiency, output, and quietness fit for the vehicles they are working to develop. The services will be contract-based and more details will be provided to interested parties.
