Abstract

An electro-hydraulic control device for a motor vehicle automatic transmission is proposed, which is designed so that it functions reliably in all operating stages. This is achieved in that the operating stages D, R and N are selected by pressure actuation of individual gearshift elements (2, 3, 12), whilst the operating stage P is selected by depressurising all gearshift elements (2, 3, 12). It is furthermore proposed that in changing over between the operating stages D, R and N two solenoid valves (7, 8, 9) be switched in each case. In addition, the selector device (15) is coupled to the parking position (1) by a second control device so that engagement of the parking position (1) is prevented when the operating stage P is not selected on the selector device (15). <IMAGE>
