Abstract

A hybrid drive (52) of a motor vehicle (50). In the motor vehicle (50), an electric motor (58) acts as the driving force on a first axle (54) and an internal combustion engine (60) as a driving force on a second axle (56). In an operation, in which only the electric motor (58) acts on the first axle (54), a check is made to determine whether the internal combustion engine (60) is to be started to drive the second axle (56), wherein a first set of conditions for a road start, taking into account first criteria, and a second set of conditions for a starter motor start, taking into account second criteria, are defined and checks are made independently of one another to determine whether the first set of conditions for a road start or the second set of conditions for a starter motor start has been met.
