摘要:
An apparatus for stabilizing a vehicle combination made up of a tractor vehicle and a trailer or semitrailer. For this purpose, the apparatus contains a first determination arrangement used to determine an inflection angle variable that describes the angle between the longitudinal axis of the tractor vehicle and the longitudinal axis of the trailer or semitrailer. The apparatus also contains a processing arrangement with which a comparison is performed as a function of the inflection angle variable and a comparison variable. The apparatus contains a first actuator arrangement associated with the trailer or semitrailer and with which a brake pressure can be established at at least one wheel of the trailer or semitrailer. The first actuator arrangement is actuated at least as a function of the comparison performed with the processing arrangement. The apparatus furthermore contains a second determination arrangement with which the comparison variable is determined as a function of the velocity of the tractor vehicle and/or as a function of whether stability interventions are being performed for the tractor vehicle.

摘要:
A device for stabilizing a vehicle is described. For this purpose, the device includes first determination device with which at least two vehicle motion quantities describing the vehicle motion, in particular in the direction transverse to the vehicle, are determined. Furthermore, the device includes second determination device with which a characteristic quantity is determined for each of the vehicle motion quantities. The second determination includes an adjustment device with the help of which the variation over time of the characteristic quantities is adjusted to the vehicle's behavior. In addition, the device device includes a control device with which intervention quantities are determined at least as a function of the vehicle motion quantities and the characteristic quantities, which are supplied to an actuator system for performing at least brake interventions and/or engine interventions with which the vehicle is stabilized.
摘要:
A method of stabilizing a motor vehicle, preferably to prevent a vehicle from rolling over about a vehicle axis oriented in a longitudinal direction of the vehicle. To do so, a quantity describing the transverse dynamics of the vehicle is determined. This quantity is compared with at least one characteristic value, in particular a threshold value, for this quantity. For the case when the quantity describing the transverse dynamics of the vehicle is greater than or equal to the characteristic value, a speed of the vehicle is reduced to or maintained at a preselectable speed value at least by braking measures on at least one wheel and/or by engine measures and/or by retarder measures (SR).

A system for determining quantities which influence the operating dynamics of a motor vehicle, the system containing at least two different control and/or regulating systems by which, independently of one another and independently of the driver, intervention measures which influence the vehicle dynamics may be performed with the help of suitable actuators, in response to one of these at least two different control and/or regulating systems carrying out an intervention influencing the operating dynamics of the vehicle, in each case the same quantity which describes the vehicle dynamics being altered by this intervention, at least two of the intervention measures influencing the vehicle dynamics being implemented in such a way that the same quantity which describes the vehicle dynamics is altered as little as possible by the intervention measures, and in the ideal case is not altered at all.

A quantity describing the wheel rpm is determined for at least one wheel in this method of determining a quantity describing the height of the center of gravity of a vehicle. A quantity describing wheel performance is determined for at least one wheel at least as a function of the quantity describing the wheel rpm of the corresponding wheel. A quantity describing the height of the center of gravity of the vehicle is determined at least as a function of the quantity that is determined for at least one wheel and describes wheel performance of this wheel. This method of determining the quantity describing the height of the center of gravity of a vehicle is used as part of a method of stabilizing the vehicle.
摘要:
A method and an apparatus relate to the detection of a tilt tendency of a vehicle about a vehicle axis oriented in the longitudinal direction of the vehicle. For this purpose, for at least one wheel, a variable describing the wheel rotation speed and at least one variable representing the transverse dynamics of the vehicle are ascertained. As a function of one of the variables representing the transverse dynamics of the vehicle, braking torques and/or drive torques are briefly generated and/or modified at at least one wheel. While the braking torques and/or drive torques at the at least one wheel are being briefly generated and/or modified, and/or after they have been briefly generated and/or modified, a variable which quantitatively describes the wheel behavior is determined for that at least one wheel, as a function of the variable describing the wheel rotation speed of that wheel. As a function of that variable quantitatively describing the wheel behavior of that wheel, a determination is made as to whether there is a tilt tendency of the vehicle about a vehicle axis oriented in the longitudinal direction of the vehicle.

A method and apparatus for stabilizing a vehicle in the presence of a tilt tendency are described. For this purpose, for at least one wheel, a variable quantitatively describing a wheel behavior of at least one wheel is determined. At least as a function of the variable that quantitatively describes the wheel behavior determined for the at least one wheel, a determination is made as to whether a tendency to tilt about a vehicle axis oriented in the longitudinal direction of the vehicle exists.
