摘要:
A method for limiting transversal acceleration (aq) in a travelling motor vehicle (210), consisting of the following steps: recognition of a driving condition with critical transversal acceleration (akr), influencing brake pressure on at least one wheel and/or influencing driving torque when the driving condition has been recognized as having critical transversal acceleration (akr). A device (130) for limiting transversal acceleration in a travelling motor vehicle has a recognition device (310) for a driving condition with critical transversal acceleration (akr), an influencing device (320) for influencing brake pressure on at least one wheel and/or for influencing driving torque when the recognition device has recognized a driving condition with critical transversal acceleration (akr).

Es wird ein Verfahren zur Abschätzung einer Querbeschleunigung eines Fahrzeugaufliegers, insbesondere zur Verwendung bei Sattelzügen, innerhalb einer elektronischen Stabilitätsregelung (ESC) oder einer Umkippverhinderung (RSC) angegeben. Hierzu wird eine gefilterte Querbeschleunigung aq_gef für den Sattelauflieger aus wenigstens den Größen für eine in der Sattelzugmaschine gemessene Querbeschleunigung aqZug und für eine gemessene Fahrzeuggeschwindigkeit V mit Hilfe einer Berechnung bestimmt. Diese kann vorteilhaft anstelle einer gemessenen Querbeschleunigung aqAufl des Sattelaufliegers verwendet werden. Hierdurch wird ein besonderer Querbeschleunigungssensor im Sattelauflieger eingespart.

The invention relates to a motor vehicle comprising a compressed-air braking system. Said vehicle has two braking cylinders (7), which can be impinged by compressed air from a compressed-air reserve by means of a manually actuated brake valve (8). The braking cylinders (7) have ABS pressure-control valves (6), which can be selectively impinged by compressed air from the compressed-air reserve, using a slip control valve (9). A stability sensor detects a motor vehicle position and a control device selectively supplies the slip control valve (9) and the ABS pressure-control valves (6) with compressed air, in accordance with the signals of the stability sensor.

The invention relates to a method for stabilizing a vehicle, preferably for preventing a vehicle from tipping over about a vehicle axis oriented in the longitudinal direction of said vehicle. To this end, a variable describing the transversal dynamics of the vehicle is determined. This is compared with at least one characteristic value for the same variable, especially a threshold value. If the variable describing the transversal dynamics of the vehicle is greater than or equal to the characteristic value, the speed of the vehicle is reduced to a predetermined speed or maintained at a predetermined speed by means of at least braking interventions on at least one wheel and/or engine interventions and/or retarder interventions.

Proposed is a method of controlling the handling of a vehicle, the method calling for at least the vehicle weight (G) and the instantaneous location of the centre of gravity (SP) to be determined from tyre-sensor signals. In a further embodiment, the invention calls for the use of a weight-distribution model which includes as its basic data the basic weight distribution of the vehicle, i.e. weights which are always the same, even at different loads. In addition, variable weights, such as those of the passengers, the luggage, etc., and their location are determined by means of the tyre-sensor signals and incorporated in the weight-distribution model as a variable weight distribution. Knowing all such data, parameters characteristic of the dynamics of the vehicle's motion can be determined, thus enabling vehicle yaw rate and slip angle to be determined by suitable calculations without being dependent on the signals from a yaw-rate sensor or a lateral-acceleration sensor.

摘要:
A vehicle behavior control apparatus is provided which is designed to estimate the state of behavior of a vehicle body and to apply the brakes to wheels for suppressing an unwanted change in behavior of the vehicle body. The apparatus determines a lateral momentum of the vehicle body during traveling to estimate the state of behavior of the vehicle body based on the speeds of the wheels and the lateral momentum and calculates a target braking effort to be produced by each of brake actuators based on the state of behavior of the vehicle.
