Abstract

A control unit (56) for a vehicle (10) with an electric drive (12) and an electromechanically actuated brake unit (14) includes a high-voltage DC link (20) disconnectably connected to a first energy store (24) of the electric drive (12), a converter (18) connected to the high-voltage DC link (20) and operable bidirectionally, and an electric motor (16) connected to the converter (18) for driving a wheel (50) of the vehicle (10). A brake drive circuit (36) is connected to the high-voltage DC link (20), and another electric motor (34), is connected to the brake drive circuit (36). A function block (55) has an input (69) for receiving a voltage signal (68) indicative of the voltage of the high-voltage DC link (20), a first output (63) for outputting a converter drive signal (60), and a first closed-loop controller unit (66) for generating the converter drive signal (60).
