Description

technical field

[0001] The present invention relates to hybrid-drive vehicles. Background technique

[0002] A hybrid vehicle is a vehicle that has at least one combustion engine (usually an internal combustion engine) and at least one electric motor, and can usually be driven with only the electric motor (low performance and range, but zero pollutant emissions) and only with the combustion engine (high performance) and range), but with significant pollutant emissions), or both.

[0003] Known hybrid vehicles operate in a "parallel" mode in which the internal combustion engine is mechanically connected to a reversible electric machine and to the drive wheels so as to transmit drive torque directly to the drive wheels. When the internal combustion engine transmits drive torque directly to the drive wheels, the reversible electric motor can be switched off and can be operated as a generator to charge a storage device, or can be operated (for short periods of time) as a motor ...
