CONTROL SYSTEM FOR A HYBRID PROPULSION UNIT FOR RECHARGING A BATTERY

摘要

A control system for a hybrid propulsion group with power bypass for an automobile including at least two driving wheels. The system includes a thermal engine, a battery, a braking system for the driving wheels, a mechanism detecting a condition of the braking system, and an infinitely variable transmission including at least two electric machines and at least two epicyclic gear chains. The thermal engine is mechanically connected with the infinitely variable transmission via a first epicyclic gear chain, the infinitely variable transmission being mechanically connected to the driving wheels via a second epicyclic gear chain. The control system is capable of controlling the thermal engine and the two electric machines so that torque supplied by the thermal engine is converted into energy by the two electric machines used as generators for recharging the battery after receiving a signal from the mechanism detecting the condition of the braking system indicating the braking system is activated.
