Abstract
A method for monitoring an oil flow, generated by an oil pump, in an oil cooling circuit of a thermal management system, includes: arranging a first pressure sensor at a first point in the cooling circuit; arranging a second pressure sensor at a second point in the oil cooling circuit; determining pressure difference values based on recorded pressures; and comparing the pressure difference values with a predeterminable comparison value for the pressure difference so as to check for a fault.
