Abstract
In a process and apparatus for braking a hybrid drive vehicle, kinetic vehicular energy is converted by the driving electric motor into electrical power, which alternatively can be absorbed by charging a traction battery or by driving a combustion engine via a generator coupled to the engine, which is functioning as a motor. According to the invention, engine braking is activated if the traction battery is fully charged, if its temperature lies outside a predetermined charging temperature range, or if the charging current due to the electrical power supplied by the driving electric motor exceeds a predetermined limit value.
