A method for controlling a chassis of a vehicle includes the steps of: detecting a vertical wheel acceleration of a wheel of the vehicle, detecting a vertical body acceleration of a body of the vehicle, determining a crest-dip indication by comparing the vertical wheel acceleration and the vertical body acceleration, and controlling the chassis on the basis of the crest-dip indication. The crest-dip indication indicates whether or not the vehicle is currently driving over a crest (K) or a dip (S). A system for controlling a chassis of a vehicle includes a wheel acceleration sensor for detecting a vertical wheel acceleration of a wheel of the vehicle, a body acceleration sensor for detecting a vertical body acceleration of a body of the vehicle, and a control unit.

Method and system for controlling a chassis of a vehicle

A method for compensating sensor tolerances of accelerometers of a vehicle. The method includes following steps: recording of measurement signals of at least three similarly oriented accelerometers, calculation of an acceleration (a) at a reference position in the spatial direction, which corresponds to the orientation of the accelerometers, low-pass filtering of the measurement signals, determination of tolerance parameters (c, c, c) of each sensor via an optimization method with the aid of the calculated acceleration (a) at the reference position, and calculation of the adjusted measurement signals from the recorded measurement signals and the tolerance parameters (c, c, c).

Method of compensating for sensor tolerances

A damping module for two damping devices on two wheel carriers of an axle of a vehicle, having a first damping circuit with a first upper damping connection to an upper damping chamber of a first damping device and a first lower damping connection to a lower damping chamber of the first damping device. A first pump device is arranged in a first pumping connection between the first upper damping connection and the first lower damping connection. Two valve combinations are oriented in opposite directions and include, in each case, a nonreturn valve (RV) and an adjustable throttle valve (DV) arranged in a first compensating connection. A second damping circuit with a second upper damping connection to an upper damping chamber of a second damping device and a second lower damping connection to a lower damping chamber of the second damping device are provided.

A device for the compensation of body movements in a motor vehicle, having an arrangement of four first piston-cylinder units which are assigned to in each case one wheel of the motor vehicle, wherein a compensation unit is provided which has a fifth piston-cylinder unit and a sixth piston-cylinder unit, wherein the pistons of the fifth piston-cylinder unit and of the sixth piston-cylinder unit are connected to one another via a coupling element, wherein at least a first number of the first piston-cylinder units and the fifth piston-cylinder unit are in fluid communication with one another and at least a second number of the first piston-cylinder units and the sixth piston-cylinder unit are in fluid communication with one another, and the compensation unit has means for compensating body movements.
