Abstract: A brake system for a transportation vehicle having a brake device for braking a wheel of the transportation vehicle, an actuator device for targetedly actuating the 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. The emergency brake device has an energy store for storing energy for actuating the brake device and a triggering device for releasing the stored energy in the energy store to actuate the brake device, the triggering device releases the energy store in response to a failure of an on-board electrical system of the transportation vehicle. Also disclosed is a method for operating a brake system and to a transportation vehicle having such a brake system.

Abstract: A method for triggering self-braking in a motor vehicle, in which following a first collision during an accident a self-braking request signal is transmitted to a brake controller by a collision sensor unit by a communications device of the motor vehicle. The multi-collision braking requested should be initiated in the event of damage to the brake controller that is caused by the first collision. The request signal is received by a control device of the motor vehicle that is disposed at a distance from the brake controller. The control device then determines whether the brake controller responds to the request signal. If no response of the brake controller is detected, the self-braking is initiated by the control device.
