Abstract
A transmission which allows for relative rotation between an input shaft in an output shaft while lowering fuel consumption. An electric motor/generator has one element fixed to a reaction-force element of a planetary gear unit in low gear. Consequently, when the vehicle is halted, the relative rotation between the input shaft and the output shaft in the transmission can be utilized as a reaction-force to drive the motor/generator as a generator. Since electric power is generated by means of the motor/generator, the generated energy is collected and fuel consumption by the engine is reduced. In other gear stages, the motor/generator is adapted to receive the energy produced when the vehicle is decelerated by means of regenerative braking.
