Patent ID: 8651238

Claim:
A device for dynamic oil filling of a transmission ( 1 ) of a motor vehicle comprising an oil overflow bore and oil cooler connections ( 2 , 3 ), the oil cooler connections communicate with an oil circuit via which the transmission ( 1 ) is filled with an initial basic oil quantity; the oil circuit, by way of the oil cooler connections, drawing off excess oil and at the same time topping off with fresh oil; the oil circuit directing a single after-dose of oil to the transmission to adjust oil in the transmission to a final oil level; the oil overflow bore is closable after the oil in the transmission has been adjusted to the final oil level; a calculating device comprising a measurement-cylinder/piston unit which communicates with the oil circuit for calculating a compensation quantity and topping off the oil in the transmission with the compensation quantity for vehicle-specific components and, a first of the oil cooler connections is a connected to a feed line of the oil circuit such that, if a result of the calculation is a negative value for the compensation quantity, the calculated compensation quantity of oil already filled in the transmission is extracted with the transmission running, and the measurement-cylinder/piston unit ( 5 ) defines a working volume ( 6 a) that corresponds to the compensation quantity.
