Brake regulating system for stabilizing the motion of a commercial vehicle
First Claim
1. A brake regulating system for stabilizing the motion of a commercial vehicle, comprising:
- a control unit configured to output, as a function of a number of input variables, at least one of;
i) a predefined manipulated variable for a brake pressure of each wheel of the commercial vehicle, and ii) a predefined manipulated variable for an output variable of a drive engine;
a steering angle sensor configured to detect a steering angle predetermined by a driver, the steering angle sensor coupled to an input of the control unit and configured to provide the steering angle to the control unit for use as one of the input variables;
a first acceleration sensor configured to detect a transverse acceleration of the commercial vehicle, the first acceleration sensor coupled to the input of the control unit and configured to provide the transverse acceleration to the control unit for use as one of the input variables;
a sensor system configured to determine a yaw rate of the commercial vehicle, the sensor system coupled to the input of the control unit and configured to provide the yaw rate to the control unit for use as one of the input variables, wherein the sensor system includes a second acceleration sensor configured to detect the transverse acceleration of the commercial vehicle, the second acceleration sensor being situated at an offset to the first acceleration sensor viewed in a longitudinal direction of the commercial vehicle;
a second sensor system configured to determine a yaw rate of at least one trailer connected to the commercial vehicle, the second sensor system coupled to the input of the control unit and configured to provide the yaw rate of the trailer to the control unit for use as one of the input variables; and
a buckling articulation angle sensor configured to determine a buckling articulation angle between the longitudinal direction of the commercial vehicle and a longitudinal axis of one of the at least one trailer connected to the commercial vehicle from the yaw rate values provided by the sensor systems, the buckling articulation angle sensor being coupled to an input of the control unit and configured to provide the buckling articulation angle to the control unit for use as one of the input variables.

Abstract
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.
