Device for open-loop and closed-loop control of an electro-pneumatic parking brake circuit, electro-pneumatic handbrake system, vehicle and method for open-loop and closed-loop control of a electro-pneumatic parking brake circuit

A device designed for controlling and regulating an electro-pneumatic parking brake circuit, the device comprising:

• a manual controller configured to actuate a parking brake via the electro-pneumatic parking brake circuit, the manual controller having a first circuit arrangement and a second circuit arrangement, the first circuit arrangement being a digital, bidirectional circuit arrangement and the second circuit arrangement being an analog circuit arrangement;
• and
• control electronics electrically connected to the manual controller,
• wherein the first circuit arrangement is connected to the control electronics via a first connection cable and the second circuit arrangement is connected to the control electronics via a second connection cable,
• wherein the first connection cable is a digital data transmission channel configured to enable a digital data transmission between the digital circuit arrangement and the control electronics,
• wherein the second connection cable is an analog data transmission channel configured to enable an analog data transmission from the analog circuit arrangement to the control electronics,
• wherein the digital circuit arrangement and the analog circuit arrangement are redundantly and simultaneously actuatable,
• wherein the analog circuit arrangement has a first redundant switching contact connected in series with a first resistor and a second redundant switching contact connected in series with a second resistor,
• wherein the second redundant switching contact and the second resistor are arranged in parallel with the first redundant switching contact and the first resistor, and
• wherein a capacitor is connected in parallel with the second redundant switching contact and the second resistor.
