Embodiment Construction

[0042] figure 1 A schematic diagram of a module 10 for an air spring system is shown according to an embodiment. The module 10 includes a data interface 12 which can be connected to a bus, in particular a CAN bus. The data interface 12 is connected to a processing unit 14 , which is likewise connected to other components of the module 10 .

[0043] According to this embodiment, the processing unit 14 is connected to two sensor interfaces 16 to which displacement sensors can be connected. The displacement sensor coupled via the sensor interface 16 provides in particular sensor values ​​17 which preferably correspond to the displacement sensor values ​​15 and include, for example, the distance between the wheel suspension and the vehicle chassis. The sensor interface 16 thus serves to receive sensor values ​​by means of the processing unit 14 , wherein the processing unit 14 is able to convert these sensor values ​​into a bus protocol in order to send them via the interface 12...

Abstract

The invention relates to a module (10) for an air spring system (60) of a vehicle (70, 82), the module (10) having: a sensor interface (16) for connecting to a sensor (61), in particular a displacement sensor (62); a valve (18, 20, 22), in particular an electro-pneumatic valve (19, 21, 23); and a data interface (12). The sensor interface (16) is configured to receive a sensor value (17) from a sensor (62). The data interface (12) is designed to send the sensor value (17) received via the sensor interface (16) to the control device (58) and to receive a control command (64) for the control valve (18, 20, 22) from the control device (58). The invention further relates to a control device (58), to an air spring system (60), to a vehicle (70, 82), to a vehicle trailer (82), to a method for operating an air spring system, and to a computer program product.

Description

technical field [0001] The present invention relates to an air spring system for vehicles, in particular commercial or passenger vehicles. In particular, the invention here relates to one or more modules and a control device for an air spring system, an air spring system, a vehicle having such an air spring system, a vehicle trailer and a method for operating an air spring system. Background technique [0002] Vehicles with air spring systems are known from the prior art. Although the air spring system is more complex than the likewise known spring systems implemented with a combination of helical or leaf springs and shock absorbers, driving comfort and safety are improved. In the case of an air spring system, the helical or leaf spring is replaced by an air spring comprising a bladder filled or capable of being filled with a gas (eg air) to thus provide a spring action. As a result, air spring systems are generally capable of protecting the vehicle's occupants, structure ...
