1, patent sharing time is different: Ford began to study hybrid technology as early as the 1990s, and the patent for hybrid power system jointly developed with Aisin has come into effect; The core PSD technology of Toyota Hybrid was not patented until 1997.
2. The patented technology is different: the drive motor and reduction gear of Ford hybrid system are coaxial, while the drive motor of Toyota hybrid system is coaxial with the engine and generator, while the reduction gear is arranged on different shafts, so there are certain differences in hybrid technology between them.
