A driving force transmission control system includes: an electric motor; a multi-disc clutch; a cam mechanism that converts rotation output from the electric motor into cam thrust force that is axial force in the axial direction of the multi-disc clutch; a pressure-conversion mechanism that converts reaction force against the cam thrust force into pressure of a fluid; a pressure sensor that detects the pressure; and a control unit that computes a command value of a current supplied to the electric motor. The control unit stores the pressure of the fluid during disengagement of the multi-disc clutch, and computes the current command value based on the pressure of the fluid to which the reaction force against the cam thrust force has been applied, and the stored pressure of the fluid..

Method for calibrating analog-controlled hydraulic valves and brake system comprising an electronic control and regulating unit in which the method is carried out


A method for determining a driving characteristic of an analogized or analog-controlled hydraulic valve of a motor vehicle hydraulic brake system in which a brake pressure generated with the aid of an electrically controllable, electric-motor-driven pressure supply device, is conducted to a wheel brake via an inlet valve and can be conducted via an outlet valve from the wheel brake into a pressure medium container. The pressure supply device and the inlet valves, and outlet valves, can be controlled by an electronic control unit.
