Abstract: A brake controller system includes a trailer mounted brake controller and a towing vehicle mounted brake controller, where the controllers exchange signals and data via a communication network so that braking actions of each of the trailer and the towing vehicle can be coordinated based on current driving statuses of the other, and where the trailer mounted brake controller includes a first interface receiving trailer status signals from sensors of the trailer; a second interface for receiving towing vehicle status signals, relating to a status of the towing vehicle and/or its mounted controller, from sensors and/or controllers in the towing vehicle; a third interface for transmitting brake control signals to brakes of the trailer; and a signal processor for generating the brake control signals based on the trailer and towing vehicle status signals.

Abstract: A method is described for stabilizing a vehicle during a braking maneuver, in which the vehicle is steered at the same time. In order to bring the vehicle back again into a controlled state as rapidly as possible, the driving state is monitored with respect to a driving situation in which the wheel slip of the front wheels is greater than a specified threshold value, and besides that, a steering requirement is present. If such a driving situation has been detected, the brake pressure is first reduced at a first front wheel and after that at a second front wheel on the other side of the vehicle, until the wheel start-up pressure is reached. Because of that, the first wheel starts up substantially faster than in response to a simultaneous pressure reduction.

Abstract: A method for braking a vehicle in a driving situation, in which an automatic braking function is active. The hydraulic pump of the brake control system may be sized to be relatively small and cost-effective, if, in critical driving situations, an additional braking device is automatically switched on or its braking capacity is increased, in order to assist the service brake and further decelerate the vehicle.

Abstract: A vehicle brake system has a plurality of hydraulic brake circuits via which wheel brake units are supplied with brake pressure. At least one wheel brake unit is connected to at least two brake circuits and supplied with brake pressure via these two brake circuits.

Abstract: A method for improving the driving stability of a vehicle, including ascertaining a trajectory to be followed by the vehicle in a situation-specific manner, an active steering system and/or a braking device being set in the vehicle in such a way that at least one transverse dynamic state variable is within an associated limiting value.

Abstract: A vehicle hydraulic brake system with wheel slip control includes two brake circuits and brake pressurization valves and brake pressure-reduction valves for each wheel brake. The two brake circuits are connected by a connecting valve in the form of a non-return valve on a side of the wheel brakes remote from the brake pressure valves. The connecting valve permits a more rapid build-up of the wheel brake pressure in the wheel brakes of the one brake circuit when a brake pressure in the other brake circuit is lower.

Abstract: A method for braking a motor vehicle in critical driving situations in which the risk exists that the transverse forces acting on the vehicle will become so great in the continued progression of its movement that it rolls over laterally. In order to reduce the risk of a lateral rollover, the vehicle operation is monitored with regard to such critical driving situations and a parking brake is activated automatically if a critical driving situation is detected.

Abstract: For improving the braking performance of a vehicle, the method is designed for brake systems that, for the wheel brakes of the front and real axle, each have a separate brake circuit each having a return pump, a plurality of the return pumps being driven by a common motor. In order to reduce the wheel standstill time of at least one wheel during an ABS control, it is provided at least partially to open a valve situated between the master brake cylinder and the inlet side of the return pump of the rear-axle brake circuit, so that the differential pressure present at the return pump of the rear-axle brake circuit becomes reduced.

Abstract: The invention relates to a vehicle brake system, having at least one supply container for delivering brake fluid to a master cylinder and/or to at least one wheel brake of the vehicle brake system. A precharging apparatus for increasing the effective pressure in the supply container is provided, in which the precharging apparatus generates compressed air for increasing the pressure. According to the invention, the precharging apparatus includes a first precharging device, which generates the compressed air from exhaust gases of an exhaust system of the vehicle, and/or a second precharging device, which generates the compressed air from the relative wind.
