Operating hybrid vehicle with first electrical machine revolution rate regulated and second torque regulated, at least some of the tim, involves operating internal combustion engine by regulating its revolution rate

摘要

The vehicle has at least first and second electrical machines (30,36) coupled by a gearbox (18) and an internal combustion engine (10) that interact, whereby, at least for some of the time., the first electrical machine is revolution rate regulated and the second torque regulated. The method involves operating the internal combustion engine by regulating it revolution rate.
