A method a speed controller includes reading in an actual angular acceleration value of a motor, comparing the actual angular acceleration value to a setpoint angular acceleration value, determining a controller output torque of an integrating I-component of the speed controller based on the comparison, and controlling the rotational speed of the motor based on the determined controller output torque.

A method of monitoring proper operation of an internal combustion engine by analyzing an engine speed includes the following steps: determination of an acceleration characteristic for each cylinder, which is a function of the engine acceleration between preferably directly successive working cycles of a specifiable number of examined cylinders; selection of the acceleration characteristics of one or a plurality of cylinders on the basis of specifiable criteria; and modification of an error characteristic provided for each examined cylinder as a function of the acceleration characteristic assigned to the cylinder, if an acceleration characteristic assigned to the cylinder has been selected.

A method for regulating the drive torque following a load change in hybrid vehicles, in which the drive torque is influenced in a load change in that a brake slip at the driven wheel of the hybrid vehicle as a result of the load change is already counteracted in the beginning phase, in such a way that any effect on the lateral stability and thus the stability of the hybrid vehicle during driving is excluded. When brake slip occurs at the driven wheels because of a load change, the drive torque is applied via the electromotor(s) of the hybrid vehicle.

A method of controlling the braking force in a vehicle has the following steps: determining actual values of controlled variables; determining setpoint values of controlled variables; comparing the actual values with the setpoint values, thereby obtaining comparison results; and influencing wheel forces on the basis of the comparison results, wheel forces being used as controlled variables, the actual values of the wheel forces being determined by a sensor system which measures the wheel force, torques having a modulation frequency being generated at the wheels, whereby the slip of the wheels and the wheel force of the wheels are modifiable, the slip of the wheels and the wheel forces of the wheels are analyzed, and the setpoint values of the wheel forces are determined from the analysis of the slip of the wheels and the wheel forces of the wheels. A system for controlling the braking force in a vehicle is also described.

A method and device setting a driving torque in a motor vehicle, in particular setting the torque as a part of an anti-slip regulation. At least two triggerable actuators are available for influencing the driving torque, where the actuators have different dynamic responses with regard to the setting of a driving torque. The core of the invention consists of the fact that first a component of the driving torque to be set is determined, and this component thus determined is used for triggering the actuator with the lower dynamics. In addition, the change in the driving torque produced by this triggering of the actuator with the lower dynamics is estimated. The difference between the driving torque to be set and the estimated driving torque is then used for triggering at least one actuator with higher dynamics.
