A method for initializing an electronically slip-controllable power braking system after a startup and an electronically slip-controllable power braking system. Power braking systems are equipped with a pressure generator for conveying pressure medium in a pressure medium circuit. The pressure generator includes a plunger unit made up of a plunger cylinder, a plunger piston, and a plunger work chamber enclosed by plunger cylinder and plunger piston. A characteristic, using which an actuation of the plunger piston is carried out by the motor during the initialization of the power braking system, is selected by the electronic control unit as a function of a piece of information present about the position of plunger piston at the start of the initialization and implemented by corresponding electronic activation of the motor.

A braking controller and method in a towing vehicle towing one or more towed vehicles as a combination vehicle provides brake control of the one or more towed vehicles based on a level of braking force applied to the towing vehicle. A non-enhanced braking mode applies a first level of braking force to the towed vehicles in a predetermined reduced proportion relative to the level of braking force applied to the towing vehicle, and an enhanced braking mode applies a second level of braking force to the towed vehicles greater than the first level of braking force. A controller deceleration command input receives a deceleration command signal which is compared against predetermined threshold deceleration rate value or against a current deceleration value being executed by the combination vehicle and, based on a result of the comparisons, either the enhanced or the non-enhanced braking modes are implemented by the controller.
