Abstract
A brake system for a transportation vehicle and a transportation vehicle having such a brake system. The brake system includes two brake circuits which each have a control unit and a battery, wherein the respective control unit actuates two of a total of four service brakes and at least one of at least two electric parking brakes. The brake system also has an electronic circuit element. The brake system forms a defect signal in response to a double fault affecting the two brake circuits and when a defect in at least one of the control units is detected, and/or in which a respective supply voltage of at least one of the control units drops below a predefined limiting value. The at least one electronic circuit element actuates the electric parking brakes when a defect signal is formed.
