Abstract: For evaluating the wheel speed signals (V(n)) required by an anti-locking or traction slip control system, a basic speed (VBas(n)) is derived from the speed signals of the individual wheels, and a wheel factor (Ki(n)) is formed for each wheel which, when multiplied by the wheel speed, forms the basic speed. For further signal processing, the wheel speed multiplied by the appertaining wheel factor is used in lieu of the actual wheel speed to form the reference speed, and the control signals.

Abstract: A sensor for measurement of yawing motion, pitching or rolling motion, particularly as suited for use in motor vehicle control systems, contains an annular hollow object (1, 2, 4) in which a magnetic fluid (MF) is located. The magnetic fluid is set into rotation by an electromagnetic field and serves as the rotating mass of the sensor. The measuring signal is obtained by measuring the forces (F) acting on the rotating mass or by generating compensation fields.

Abstract: A circuit configuration for detecting wheel sensor malfunctions includes circuits which process and analyze the sensor signals (s.sub.1 to s.sub.4), which ascertain the speed (v.sub.Rmax, v.sub.Rmin), deceleration and acceleration (a.sub.R) of the individual wheels and which compare these values with one another and compare them with predetermined threshold values (a.sub.0, v.sub.0, v.sub.1, -a.sub.1). Upon the detection of signals or combinations of signals typical of a sensor malfunction, the control will be disconnected after a predetermined period of time (T, T1+T2). When the measured acceleration values (a.sub.R) are below an overspeed threshold (a.sub.0) and the speed at any one of the remaining wheels is below a bottom speed threshold (v.sub.0), the control will be disconnected as soon as the speed of a wheel (v.sub.Rmax) exceeds a top speed threshold (v.sub.1). A time monitoring function is started in the presence of a measured acceleration value (a.sub.R) which is above the overspeed threshold (a.sub.0) and in the presence of a measured speed value (v.sub.Rmin) which is below the bottom speed threshold (v.sub.0) as soon as a measured speed value (v.sub.Rmax) exceeds a top speed threshold (v.sub.1). Anti-lock and traction slip control will be disconnected upon lapse of the predetermined time period.

Abstract: Taking into account the signals of tire sensors to adjust the driving performance of a vehicle is known. For example, the signals of contact sensors can be used to indicate the forces which act on the individual vehicle tires. According to this new method, to permit a control intervention in the shortest possible real time, especially those forces are used as a control quantity which are determined by the signals from tire sensors. This means that nominal conditions of the vehicle are converted into nominal forces Fi,Soll which are compared to the actually applied forces Fi,Ist. The so produced differences in forces &Dgr;Fi are then converted by a wheel force controller (2), for example, into brake pressure variations or variations of the engine drive torque which then influence the vehicle (3) as a controlled system. Because the forces (Fi,Ist) which act on the vehicle tires are quantities describing the driving condition of the vehicle which can be determined most quickly, the reaction time of the system is extremely short, and therefore driving performance can be better controlled.

Abstract: The present invention relates to a method of error detection of a microprocessor in a control unit of an automotive vehicle, wherein a control unit can send and receive data by way of a data bus, wherein the output of the microprocessor is monitored by a watchdog circuit, wherein the watchdog circuit compares the signals output by the microprocessor with predetermined signal patterns, and an error is detected when the signals output by the microprocessor are not concurrent with one of the predetermined signal patterns. Further, the present invention relates to a method of error detection of microprocessors in control units of an automotive vehicle, wherein a first control unit can exchange data with at least one further control unit by way of a data bus, wherein the data necessary for performing at least part of the controlling or regulating task of the first control unit are sent from this first control unit to the at least one further control unit by way of the data bus, so that corresponding to the controlling or regulating method in the first control unit, the data to be determined and, if necessary, output by the first control unit are reproduced by the at least one further control unit, and an error is detected when the data determined in the first control unit differ from the data determined in the at least one further control unit. Instead of the transmission by way of the data bus, sending the data necessary for performing the controlling or regulating task of the first control unit directly to the further control unit is also possible.
