    摘要: For regulating the driving dynamics of a road vehicle, setpoints for the yaw rate {dot over (&PSgr;)} and the float angle &bgr; of the vehicle are generated continuously by evaluating a simulation computer implemented vehicle model. The simulation computer generates control signals for activating at least one wheel brake of the vehicle based on a comparison of the reference values {dot over (&PSgr;)}SO as a setpoint, and the actual values {dot over (&PSgr;)}I of the yaw rate continuously recorded by a yaw rate sensor. The vehicle model is represented by a linear differential equation system of the form [P]·({overscore ({dot over (X)})})=[Q]·({overscore (X)})+({overscore (C)})·&dgr;(t). The driving-dynamic state values &bgr;Z(k−1) and {dot over (&PSgr;)}Z(k−1) are updated at a point in time t(k−1), followed by a point in time t(k) that is later by a clock time interval TK, by evaluation of the system of equations X ⁡ ( k ) = {   ⁢ T k ⁢ - [ Q ] } · {   ⁢ T k ⁢ · X ⁡ ( k - 1 ) + C · δ ⁡ ( k ) } with the values of the matrix elements pij and qij updated for that point in time TK.

    摘要: A method sets the braking effect of the retarder brake as a function of the absolute value of the difference between wheel speed values which are derived from wheel speeds at wheels which can be influenced by the retarder brake and from wheel speeds at wheels which cannot be influenced by the retarder brake. The braking effect is reduced if the absolute value of the difference exceeds a prescribed limit value which is lower than the absolute value of the difference when one of the wheels starts to tend to lock. The effect of the retarder brake can thus already be reduced significantly before the locking point is reached so that the risk of wheels locking which otherwise exists owing to the comparatively slow decrease in braking torque of retarder brakes and thus the associated swerving of the axle of the retarder brake are reliably avoided.

The projecting wall defines a cavity in the bottom surface of the sole, so that the sand becomes compacted when walked upon by the user. Suitable straps are secured to the top of the sole surface, for coupling to the user's foot.

    摘要: A method controls brake pressure for a motor vehicle pressure medium-actuated power brake system in which the adjustment of a proportionality factor (k) between deceleration and brake pressure starting from an initial value (ko) is limited to a range bounded by a lower limit value and an upper limit value in which range the initial value (ko) is contained. This produces a warning travel of the pedal when excessive deviation of the brake pressure from the expected value occurs. The warning travel informs the driver of the braking effect which is deviating excessively from the expected degree. Methods are known in which a specific travel (sp) of the brake pedal is interpreted as a setting of a specific desired deceleration (zs) of the vehicle and the required brake pressure is set automatically if appropriate by incrementally adjusting a variable proportionality factor (k).

    摘要: The gradient of a roadway in the direction of travel of the vehicle is identified from signals present in the vehicle without any additional sensor systems. A freely rolling state of the at least one driven axle of the vehicle is detected at least once. In this state, the wheels of the driven axle also roll free of slip. In order to balance out the wheel speeds between the driven axles and the non-driven axles, the difference speed between the wheel speed of a driven axle and the wheel speed of a non-driven axle is identified. At the same time, the value of the braking, that is to say the value of the deceleration of the vehicle, is measured. The value of a gradient constant is identified from the identified values of the difference speeds and the braking operations. The gradient of the roadway can be determined with the gradient constant from the values of the difference speed and the values of the braking then identified. The gradient information can then be used to control the vehicle.
