  • Method for electrohydraulically controlling a motor vehicle transmission and electrohydraulic controller for a motor vehicle transmission
    Publication number: 20020107108
    Abstract: A control current is converted into an activation pressure for a transmission actuator by a pressure regulating valve. Both a control current at a given time and the activation pressure at the given time are fed back to a regulator. A setpoint value for the activation pressure in a partial range of a torque to be transmitted is converted by the regulator into the control current in dependence on the control current at the given time and otherwise as a function of the activation pressure at a given time. The current measuring device for determining the control current at the given time is adjusted here in such a way that a high resolution is obtained in the partial range.
