The keywords for the future powertrain technologies are high efficiency and low emissions. The hybrid powertrain system has achieved superior power performance as well as higher system efficiency and is expected to be a core powertrain technology because it is compatible with various power sources including fuel cells. However, the penetration of new powertrains depends on the compatibility with the environmental technologies, the infrastructure and the attraction with reasonable price. Toyota's approach towards the ultimate powertrain varies widely from current mainstream to future technology. Gasoline and diesel engines will be the mainstream power sources for the next 20 - 30 years. Model based control is one of the essential technologies for managing the rapidly increasing powertrain control complexity. It is also useful to efficiently develop coordinated control systems that integrate powertrain control and other automotive control systems. Model based development of control software including automatic embedded code generation is about to be deployed in production development to improve the control system development productivity. Model based verification and validation is highly required to further improve the development process. The hybrid vehicle system is promising as one of the systems capable of realising compatibility between fuel economy and emissions. Toyota believes that the hybrid system with a sophisticated control system is the core technology in the coming future.
