Motor vehicle hybrid drive has controller that regulates charging pressure depending on operating conditions, limits charging pressure by regulating electrical power of electrical machine

摘要

The drive has an internal combustion engine and at least one electrical machine as a drive source, at least one electrical accumulator and an electronic controller that regulates the engine charging pressure depending on defined operating conditions and limits the charging pressure produced by an exhaust gas turbocharger by regulating the electrical power of a second electrical machine(s). The drive has an internal combustion engine (6) and at least one electrical machine (8) as a drive source, at least one electrical accumulator (14) and an electronic controller (10) for automatically operating the machine as a motor or generator. At least one exhaust gas turbocharger (16) feeds fresh gas to the engine for combustion. At least one second machine (32) operable as a generator has a drive connection to the turbocharger's shaft (22), is electrically coupled to the accumulator to supply current and has a control connection to the controller. The controller regulates the engine charging pressure depending on defined operating conditions and limits the charging pressure produced by the turbocharger by regulating the electrical power of the second electrical machine(s).
