  • Device and method for controlling a current collector for a vehicle
    Patent number: 11845343
    Abstract: A device and method for controlling a pneumatically actuated current collector for a vehicle, wherein the device includes a controlled system having a first pressure controller, a second pressure controller, and an actuation device, where at least one sensor, which is connected for signal conduction to a contact force controller of the controlled system, can be advantageously arranged on the current collector, the first pressure controller is coupled to the contact force controller, the second pressure controller and a pressure supply for signal conduction, the second pressure controller having a connection point for an actual pilot pressure from the first pressure controller, and signal-conducting connections are provided between the second pressure controller and the pressure supply and between the second pressure controller and the actuation device such that rapid adaptation of a contact force to variable operating conditions is enabled.
