Abstract

A hybrid vehicle has an internal combustion engine (10) and a hybrid drive (12) that has an electric machine (11) and a transmission (13) having a drive output. During driving under purely internal combustion engine (10) power, only the internal combustion engine provides a drive torque at the drive output. During driving under purely electric motor power, only the electric machine (11) provides a drive torque at the drive output. During hybrid driving, the internal combustion engine (10) and the electric machine (11) each provide a drive torque at the drive output. The hybrid vehicle also has a pump unit (16, 20). The pump unit (16, 20) can be driven by the electric machine (11) of the hybrid drive (12).
