[ What is claimed is:] [1.] An actuation unit for an electronically controlled hydraulic vehicle braking system, comprising:a brake booster which can be actuated by a brake pedal and which comprises a master cylinder and a reservoir for hydraulic fluid;a first brake means which is coupled with at least a first vehicle wheel and which is connectable with the master cylinder via an electronically controlled valve arrangement in a basic position or, in an actuation position, is disconnectable from same;a means for the simulation of the brake pedal behavior which is connectable with the master cylinder and comprises a spring arrangement adapted to act against the hydraulic pressure from the master cylinder, characterized in that a characteristics modeling means is associated with the simulation means which influences the behavior of the simulation means as a function of the direction of movement, the actuation force, and the actuation speed of the brake pedal, and which comprises at least one throttle forwarding hydraulic fluid upon actuation of the brake pedal and a second throttle forwarding hydraulic fluid upon release of the brake pedal.
