CONTROL SYSTEM FOR A HYBRID PROPULSION UNIT FOR RECHARGING A BATTERY

摘要

The invention relates to a control system for a hybrid propulsion group with power bypass for an automobile including at least two driving wheels, comprising a thermal engine (1), a battery (4), a braking system (11) for the driving wheels, means for detecting the condition of the braking system (11c) and an infinitely variable transmission (5) including at least two electric machines (2a, 2b) and at least two epicyclic gear chains (6a, 6b), the thermal engine (1) being mechanically connected with the infinitely variable transmission (5) via a first epicyclic gear chain (6a), the infinitely variable transmission (5) being mechanically connected to the driving wheels via a second epicyclic gear chain (6b), characterised in that the control system is capable of controlling the thermal engine and the two electric machines (2a, 2b) so that the torque supplied by the thermal engine (1) is converted into energy by the two electric machines (2a, 2b) used as generators for recharging the battery (4) after receiving a signal from the means for detecting the condition of the braking system (11c) indicating that the braking system (11) is activated.
