A new differential configuration of hybrid electric vehicle with torque regulationloop

الملخص EN

The most significant weakness of hybrid electric vehicles (HEV) is the high construction cost and the complicated control strategies due to multiple power sources [1], [2] .In this paper a new developed configuration of hybrid vehicle is presented.

The new configuration is simple, cost-effective and easy to implement.

The differential unit, which acts as mechanical torque-overflow keeps engine torque within a predefined value.

This is achieved by the aid of torque loop attached to one terminal of the differential.

The new configuration proved to act continuously varying transmission (CVT) and also can perform efficient control strategies.

Minimum emissions can be assured by running the IC-engine within best engine performance zone which is characterized by engine torque and engine speed.
