    摘要: To determine the transverse acceleration of a vehicle, in particular as an input quantity for an electronic vehicle control system such as ABS, TCS, EBV, etc., the output signals of wheel sensors representative of the rotational behavior of the individual vehicle wheels are evaluated. The correction factors representing the differences of the tire tread circumferences of the individual wheels are determined. A short-time correction factor and a long-time correction factor KZ and LZ are produced in each case for the non-driven vehicle wheels. A difference between the long-time correction factor and the short-time correction factor of the respective wheel is determined and evaluated in a filtering and adapting circuit. The quotient KZ/LZ of the short-time correction factor and the long-time correction factor of the respective wheel is calculated, and the difference is produced between the quotients of the left and right non-driven ##EQU1## wheels. The transverse acceleration of the vehicle Q.sub.FZ is the result of the relation

    摘要: The present invention describes a process for a vehicle including an electronic control system, which processes input signals representative of the rotational behavior of the individual wheels, and wherein the differences of the tire tread circumferences of the individual wheels are determined by way of short-time and long-time correction factors. The long-time correction factors LZ.sub.n. are determined from the differences D.sub.R1 between the short-time correction factors KZ.sub.R1 and the long-time correction factors LZ.sub.R1 of the respective wheel by averaging LM.sub.r1 the differences during a predetermined time interval and by evaluating and weighting the average value. For the quick identification of an emergency wheel, every time the vehicle engine is started, the long-time factor LZ.sub.R1 is equalled once to the short-time factor KZ.sub.R1 of the respective wheel, if simultaneously the short-time correction factors of three wheels are approximately equal and the short-time correction factor of the fourth wheel adopts a relatively high value, which is within a predetermined range, for a predetermined time interval or minimum time interval, and if the short-time correction factor of the fourth wheel remains approximately constant during this time interval.

    摘要: To improve the control behavior of a brake system with anti-lock control (ABS) on the occurrence of road irregularities, a brief braking pressure reduction phase with a major braking pressure reduction on a wheel, followed by a high re-acceleration of the wheel, is interpreted as a road irregularity if the quotient of the duration of the braking pressure reduction and of the total duration of the pressure reduction phase multiplied by the re-acceleration of the wheel or the maximum value of the re-acceleration or if the acceleration variation or the maximum value of the acceleration variation exceeds predetermined limit values, and a braking pressure rise that is increased compared to the standard ABS control is caused as a result of detection of the road irregularity.

    摘要: The present invention relates to a method of detecting the roll angle of a cornering vehicle which comprises at least one axle and at least two wheels, the vehicle being equipped with a transverse acceleration sensor means which senses the transverse acceleration that acts on the center of gravity of the automotive vehicle generally in the horizontal plane of the vehicle. To provide a method which does not require an additional sensor means and is virtually independent of given vehicle characteristics or dimensions, the component of the transverse acceleration which essentially acts in the horizontal plane of the vehicle is detected by the transverse acceleration sensor means during cornering. In addition, a condition variable which is correlated to the centrifugal acceleration acting on the center of gravity is detected, and the roll angle of the vehicle is calculated from the difference between the detected component of the transverse acceleration and the determined centrifugal acceleration, the said difference being weighted with a factor.

    摘要: A circuit arrangement for a brake system with electronic brake force distribution control includes circuits which determine the deceleration of the rear wheels and the deceleration of a vehicle or a corresponding reference quantity. The discrepancy of the filtered rear-wheel deceleration from the vehicle deceleration is evaluated for brake force distribution control. To this end, an output signal is produced by way of a differentiator and integrator comparing the rear-wheel deceleration and the vehicle deceleration, and the output signal is evaluated for the control of the braking pressure in the rear-wheel brakes.

    摘要: A control valve conditioning method in an electrohydraulic pressure control unit comprising at least one electrically triggered solenoid valve that is controlled in an analog manner. The solenoid valve is operated at a specific operating current according to a functional correlation or characteristic diagram between the valve current and the differential pressure characteristic curve when the pressure is controlled, said functional correlation or characteristic diagram being stored in the pressure control unit. The method comprises the following steps: a) temporarily applying at least one anti-hysteresis pulse to the solenoid valve during which a current is set far below or far above the operating current in the valve; b) applying the anti-hysteresis pulse at the desired operating current before or during controlled operation, and c) applying the anti-hysteresis pulse wherein the duration is limited in such a way that the anti-hysteresis pulse has largely no influence on the brake pressure.

    摘要: The present invention relates to a method for improving an anti-lock control system, in particular for improving driving stability during braking on laterally different coefficients of friction. According to the method, a desired yaw rate is determined using at least one steering angle signal of a steering angle sensor and an actual yaw rate is determined using at least one yaw rate sensor, and the instability is evaluated using a parameter that serves for a qualitative and quantitative judgment of a deviation between the actual yaw rate and the desired yaw rate. Both yaw rate deviation and the time derivative of the yaw rate deviation are used to determine the parameter.
