    摘要: 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.

    摘要: The present invention provides a process for controlling the driving behavior of an automotive vehicle which determines from tire sensing signals at least the vehicle mass and the momentary location of the mass center of gravity of the automotive vehicle. According to another embodiment of the invention the use of a mass distribution model is suggested containing, as the basic data, the basic mass distribution of the vehicle, namely such masses that are always identical even if the loading is different. Moreover, variable masses, such as location and mass of passengers, luggage etc., are determined from the tire sensing signals and are incorporated into the mass distribution model to provide a variable mass distribution. With such such data being known, also details typical of the driving dynamics of the vehicle can be determined so that yawing angle speed and side slip angle of the vehicle can be computed accordingly with no need of relying on the signals of a yaw rate sensor or a transverse acceleration sensor.

    摘要: To improve the control behavior of an anti-lock brake system, which also permits active braking intervention when the brake pedal is not applied, braking pressure is introduced into the wheel brake of the bend-outward front wheel, or asymmetrically into the wheel brakes of both front wheels upon identification of a cornering situation and simultaneous deceleration of the vehicle if additionally the slip on the bend-outward rear wheel exceeds the slip on the bend-outward front wheel. ‘Veering’ or overspinning of the vehicle is this way counteracted.

    摘要: A microprocessor configuration for a control system of a vehicle comprises a plurality of microprocessor systems (4,5,6) which are interconnected by bus systems (1,2,3) and include an anti-lock and/or traction slip control system and further control systems, which require complex computing operations, as well as an input signal conditioning system (SC). For the purpose of error detection one part of the data processing is performed “symmetrically” redundantly in a plurality of microprocessor systems and another part of the data processing is additionally performed (“asymmetrically” redundantly) in accordance with simplified algorithms. Two like master microprocessor systems (5,6) are provided which serve the symmetrically redundant data processing. The input signal conditioning and the processing in accordance with simplified algorithms are installed in a third microprocessor system (4). The output and/or intermediate results are compared for redundancy; moreover, the data processing performed in these microprocessor systems is each time compared and checked for plausibility with the results of the simplified data processing.

    摘要: A circuit arrangement for conditioning and evaluating the signals emanating from wheel sensors in a first stage determines the sensor(s) supplying the highest useful signal at very low wheel speeds. The signal from the most sensitive sensor is delivered when the wheel speed is below the predetermined speed threshold. Above the speed threshold, however, the signal from a sensor arranged on a driven vehicle wheel is used as the vehicle speed signal. The circuit is especially suitable for anti-lock and traction slip control systems which supply speed signals which can also be evaluated for other vehicle control or regulating systems.

    摘要: 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.

    摘要: A circuit configuration for a brake system with anti-lock control and traction slip control comprising, wheel sensors for generating electric signals representing the wheel rotational behavior and circuits for the cornering identification is provided such that lateral reference speeds (13, 14) are formed by virtue of selection circuits (8, 9) which select leading wheel speed according to specific criteria, and by virtue of a filter means (10, 11) whose time constants (12) are variable. A difference signal (DVS) is formed of the lateral references speeds (SRG.sub.L, SRG.sub.R), the magnitude of which is variable by inverse feedback. This difference signal (DVS) serves to actuate an adaptation circuit (18) as a function of the vehicle reference speed (V.sub.REF). The adaptation circuit influences on the control thresholds of the anti-lock control and traction slip control to adapt the control to the particularities of cornering.
