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 brake regulating system particularly suitable for stabilizing the motion of a commercial vehicle is described, in which a control unit outputs, as a function of a number of input variables, a predefined manipulated variable for the brake pressure of each wheel of a commercial vehicle and/or a predefined manipulated variable for an output variable of the drive engine. For detecting the input variables, the input of the control unit is connected to a steering angle sensor for detecting a steering angle predetermined by the driver, to a sensor system for determining the yaw rate of the commercial vehicle, and to a first acceleration sensor for detecting the transverse acceleration of the commercial vehicle.
摘要:
A method for stabilizing a vehicle in particular to prevent overturning, in which a strategy is selected from at least two different strategies as a function of a quantity describing or corresponding to whether an overturn tendency about a vehicle axis oriented in the longitudinal direction of the vehicle exists, and which may be determined at least as a function of a quantity describing or corresponding to the wheel behavior of at least one wheel, and which may also be determined a function of a comparison which is carried out as a function of a quantity describing or corresponding to the lateral dynamics of the vehicle and of a characteristic value that is determined as a function of a quantity describing or corresponding to the instantaneous friction conditions.
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.

A steering device for vehicles having a pair of wheels which can be steered freely as a function of the current driving state of the vehicle or whose steered position can be locked by an electronically actuable locking device, having an electronic control device and having sensors which are connected to the electronic control device and have the purpose of monitoring current driving state values, with the electronic control device actuating the locking device when a minimum velocity of the vehicle is exceeded, in such a way that the steered position of the pair of wheels is locked, characterized in that driving state values which characterize critical driving situations are additionally stored in the electronic control device, in which the steered position of the pair of wheels is locked in critical driving situations, and in which, after a critical driving situation, the locking device does not release the pair of wheels again until predefined critical driving state values are undershot at least for a predefined period of time.
摘要:
A method for recognizing a trailer or semitrailer of a motor vehicle which includes activating at least one brake light of the trailer or semitrailer, independently of the driver, measuring a current flowing in a line assigned to the brake light of the trailer or semitrailer and ascertaining the presence or the absence of a trailer or semitrailer on the basis of the measured current.
摘要:
A method for increasing the driving stability of a vehicle, particularly of a commercial vehicle, which counteracts a vehicle instability by a control intervention in a control system operating the drive and/or the brakes of the vehicle, in which the control intervention occurs as a function of the ratio between the height of the center of gravity of the vehicle and a spring constant of the vehicle suspension.
