Abstract: An installation for the automatic shifting of change-speed transmissions, especially for motor vehicles, in which actuating devices are provided for the engagement and disengagement of the speeds, which are controllable by way of control means by at least two influencing magnitudes, particularly output rotational speed and torque; an electronic control unit having a programmed, constant-value memory device is provided, in which is stored at least one set of output rotational speed limit values coordinated to the individual speeds and torque steps, while at least the influencing magnitudes of torque and engaged speed are adapted to be applied to the electronic control unit by way of corresponding inputs; and output of the constant value memory device is operatively connected with a rotational speed comparison unit, in which the output rotational speed limit values given out by the constant-value memory device are adapted to be compared with the prevailing output rotational speed, whereby in this rotational spe

Abstract: A brake force control system for vehicles, especially for motor vehicles in which one or several electrical signals dependent on the wheel acceleration are compared with predetermined threshold values and in which the resultant electrical signals are utilized for the control of actuating elements such as solenoid valves in the brake circuit, whereby the electrical acceleration signals are weighted in a manner known as such and this weighting is adapted to be influenced or even discontinued when exceeding the threshold value and/or in dependence on the polarity of the acceleration signal.
