Braking system, method of operating a braking system and transportation vehicle with a braking system

A method for operating a brake system that includes a wheel brake device for braking a wheel of the transportation vehicle, an actuator device for targetedly actuating the wheel brake device, a control device for controlling the actuator device, and an emergency brake device for braking the wheel in response to a malfunction of the transportation vehicle wherein an on-board electrical system is rendered unable to provide an amount of electrical current required to actuate the actuator device of the brake system, the method comprising:

• holding a triggering device in a basic position in response to an on-board electrical system providing electrical current required to actuate the actuator device;
• using a determining device of the transportation vehicle to determine vehicle parameters and environmental parameters that have an influence on a braking input for reliably braking the transportation vehicle;
• using a configuration device to configure the actuation, providable using the emergency brake device, of the wheel brake device;
• using the triggering device to release the stored electrical energy in an energy store in response to the vehicle malfunction, wherein the on-board electrical system is no longer able to provide the electrical current required to actuate the actuator device;
• and
• using the electrical energy released from the energy store to actuate the wheel brake device,
• wherein the configuration device is configured to set the maximum electrical energy delivered by the energy store and/or to set a delivery rate of the electrical energy delivered by the energy store.
