Abstract

A temperature control system for a hybrid powertrain includes a first coolant circuit for temperature control of a first drive device of the hybrid powertrain and a second coolant circuit for temperature control of a second drive device. The second coolant circuit has a first subcircuit, connected for heat transfer to the second drive device, and a second subcircuit, connected at least temporarily for heat transfer to an energy store of the second drive device. The first and second subcircuits are operable separately from one another. A coolant duct is connected to the first drive device for heat transfer and is fluidly connected in a first operating mode with the first coolant circuit in the absence of a fluid communication with the second coolant circuit, and fluidly connected in a second operating mode with the second coolant circuit in the absence of a fluid communication with the first coolant circuit.
