    摘要: To improve the control behavior of an anti-lock control system, in a method wherein the rotational behavior of the wheels is measured and evaluated and a vehicle reference speed, wheel slip data and wheel acceleration data and other control parameters are determined, the lowest wheel speed (v.sub.min) is continuously compared with the highest wheel speed (v.sub.max) during a braking operation. In the event of an approximate correlation between the lowest (v.sub.min) and the highest (v.sub.max) wheel speed and if the correlation lasts longer than a predefined length of time (T1, T2), the pressure in the brakes of the front wheels is permitted to increase or caused to increase after this length of time. The duration of the predetermined length of time (T1, T2) can be varied as a function of the acceleration or deceleration (v.sub.3, v.sub.4) of the non-driven wheels.

    摘要: A method of improving the control behavior of a controlled brake system, wherein the rotational behavior of the individual vehicle wheels is measured and evaluated for determining control quantities, and wherein slip threshold values for the commencement of the control are predetermined, includes that the slip threshold of a wheel is increased for a predefined time interval as a function of the acceleration after preceding instability in order to suppress the effects of road surface irregularities. This increase may be carried out in two steps as a function of the exceeded acceleration limit values.

    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 method for increasing the maneuverability and driving stability of an automotive vehicle during cornering, the rotational behavior or the wheel slip of the individual vehicle wheels is monitored, and the distribution of the brake force to the curve-outward wheels compared to the brake force conducted to the curve-inward wheels is varied in dependence on the wheel rotational behavior and on the slip of the wheels. When cornering is detected, a total deceleration of the vehicle that corresponds to the driver's request is determined, and a vehicle deceleration that corresponds to the driver's request is achieved by increasing the brake force at the curve-outward wheels and decreasing or maintaining the brake force at the curve-inward wheels.

    摘要: The present invention relates to a method for electronically regulating brake force distribution to the front axle and the rear axle of a motor vehicle (EBV control), wherein the rotational behavior of the vehicle wheels is determined, compared with the vehicle speed or vehicle reference speed and/or with the changes of these variables, and evaluated to limit the slip on the rear-wheel brakes by modulating the braking pressure. The brake force distribution is controlled in dependence on the sum signals obtained by addition of acceleration values determined on each individual rear wheel and/or by addition of slip values determined on each individual rear wheel. It is particularly arranged for to weight the sum signals with variable sum factors and evaluate them as a criterion for triggering the EBV control (so-called EBV plus control).

    摘要: In a method of improving the control behavior of an anti-lock control system, criteria for identifying a cornering situation and the direction of curve are obtained from the rotating behavior of the vehicle wheels. For cornering identification, the wheel slip values (&lgr;i) are filtered by way of a first order, low pass and the filtered values are compared. The time constant (T) of the low pass filter is varied as a function of the acceleration (ai) of the respective wheel (i). The time constant (Ti) of the filter starting from a minimum value (Tmin), is increased according to the relation Ti=Tmin+(agrenz−ai)/k1 as soon as the acceleration (ai) of the respective wheel (i) drops below a predetermined limit value (agrenz).
