AN ELECTRIC VEHICLE WITH CONTROLLABLE GENERATOR

摘要

The present invention relates to a drive system wherein a typically chain power transmission system is replaced by an electric motor and where the electric motor is powered by a generator, and where the generator is connected to a dynamic naturally powered source through a transmission mechanism, the dynamic naturally powered source being, such as, but not limited to, a biologically driven source like the pedals of a bike operated by a human being. This may be directly linked or there may be energy storage means in-between. The present invention introduces such a vehicle where the generator is capable of adding a controllable counter torque, or more generally a counter force, to the operation of the transmission mechanism and where the energy generation in the generator is related to the counter torque.

1. A device operating a dynamic device speed related to conditions external to the device where the device at least partly is powered by a dynamic source operating a generator at a generator speed where the energy generated in the generator depend on a counter torque, Tcounter, and where the generator is controlled with an input reference R depending on the generator angular speed and the device speed.
