Method For Changing From Electrical Operation To Hybrid Operation In A Vehicle Hybrid Drive And Vehicle Hybrid Drive
A method for changing from electrical operation to hybrid operation in a vehicle hybrid drive is provided. The method includes detecting an increase in a target traction power and starting the internal combustion engine. When the internal combustion engine starts, the method includes outputting a positive torque by generating an increasing generator power. The generator power is used together with an electrical power of a storage unit for generating electrical traction power. The generator power is generated while the internal combustion engine is not yet fully coupled to an output. The method includes fully coupling the internal combustion engine to the output after the generation of the increasing generator power has begun. After the internal combustion engine has been fully coupled, the method includes reducing the electrical power of the storage unit to a non-positive value and adjusting the generator power in accordance with a predetermined energy balance.

A high-voltage vehicle electrical system is equipped with a ground potential (M) and a high-voltage potential (HV) which is insulated from the ground potential (M) by means of a two-stage insulation. The two-stage insulation has a first insulation device (I1) which insulates the high-voltage potential (HV) from the potential island (PI). A second insulation device (I2) of the two-stage insulation insulates the potential island (PI) from the mass potential (M). The potential island (PI) is connected to the mass potential (M) by means of a dissipation element (R). For the event of an insulation fault in the two-stage insulation, the dissipation element (R) is designed to generate a current which is below a danger threshold and above a sensitivity threshold of an insulation monitor (IM).
