Abstract

The invention relates to a control system for a motor vehicle, especially for a commercial vehicle that has a box body supportable on a chassis, with at least one detection means generating detection data for detecting the road profile in front of the vehicle in the direction of travel and a control device for controlling at least one controllable spring and/or damper unit depending on the detected data, wherein the at least one spring and/or damper unit for suspension and damping of the box body in the direction of a vertical axis of the vehicle can be connected to the box body and the chassis.

Claims

1. A control system for a motor vehicle, especially for a commercial vehicle, that has a box body supportable on a chassis, with at least one detection means generating detection data for detecting the road profile in front of the vehicle in the direction of travel and a control device for controlling at least one controllable spring and/or damper unit depending on the detected data,

wherein

the at least one spring and/or damper unit for suspension and damping of the box body at least in the direction of a vertical axis of the vehicle is connected to the box body and the chassis.

2. The control system as claimed in claim 1, which comprises:

a multiplicity of controllable spring and/or damper devices, which can be controlled independently of each other.

3. The control system as claimed in claim 1, which comprises:

one or more sensors, which detect acceleration parameters describing the motion of the box body, in particular a box body acceleration in the direction of the vertical axis of the vehicle and/or a pitch angle acceleration of the box body and/or a roll angle acceleration of the box body.

4. The control system as claimed in claim 1 which comprises:

one or more sensors, which detect the position of the box body relative to a reference plane, wherein the reference plane is determined by the extension plane of the vehicle chassis.

5. A motor vehicle, especially a commercial vehicle with a box body supported on a chassis, which comprises:

a control system as claimed in claim 1, wherein the box body is connected to the chassis via the at least one spring and/or damper unit for suspension and damping, at least in the direction of a vertical axis of said vehicle.

6. The control system as claimed in claim 2, which comprises:

one or more sensors, which detect acceleration parameters describing the motion of the box body, in particular a box body acceleration in the direction of the vertical axis of the vehicle and/or a pitch angle acceleration of the box body and/or a roll angle acceleration of the box body.

7. The control system as claimed in claim 2 which comprises:

one or more sensors, which detect the position of the box body relative to a reference plane, wherein the reference plane is determined by the extension plane of the vehicle chassis.
