The disclosure relates to a method for securing a vehicle, preferably a commercial vehicle, in an emergency braking situation, wherein the vehicle has a vehicle bus system and a braking system, the method having the following steps: monitoring signals on the vehicle bus system; detecting an emergency brake signal provided by a driver assistance system on the vehicle bus system; ascertaining whether the vehicle is at a standstill; bringing a braking device of the braking system into a braking position if a standstill of the vehicle is ascertained. The disclosure also relates to a control unit for a vehicle, a computer program, a braking system for a vehicle, and a vehicle.

Method for securing a vehicle

A relay valve module for an electronically controllable pneumatic brake system for actuating wheel brakes of a utility vehicle includes: a reservoir connection for receiving a reservoir pressure; a brake control pressure connection for receiving a brake control pressure; at least one first service brake connection for outputting a service brake pressure; a relay valve with a relay valve reservoir connection, which is connected to the reservoir connection, a relay valve working connection, which is connected to the first service brake connection, a relay valve ventilation connection, and a relay valve control connection; an electropneumatic pilot control unit, which is connected to the reservoir connection, the electropneumatic pilot control unit providing a pilot control pressure; and a shuttle valve with a first shuttle valve inlet, a second shuttle valve inlet, and a shuttle valve outlet. The first shuttle valve inlet is connected to the brake control pressure connection.

Relay valve module for use as an axle modulator and trailer control module

A brake device () includes a service brake valve () that produces an actuation-dependent pressure at a service brake valve outlet () when an operating means () is actuated. The brake device () includes a brake actuator () with a brake actuator inlet (). The service brake valve outlet () is connected to the brake actuator inlet () via a pressure connection (). The pressure connection () includes a directional control valve () and a check valve (). The check valve () is bypassed in a first valve position of the directional control valve () to allow a fluid flow from the brake actuator inlet () to the service brake valve outlet () and a fluid flow through the check valve () from the brake actuator inlet () to the service brake valve outlet () is largely prevented in a second valve position of the directional control valve ().

Brake device and use of a direction control valve in a brake device

The application discloses a method for controlling a pneumatic brake system of a vehicle. The method includes the step of modulating a pilot-control brake pressure by means of an electropneumatic pilot-control valve in venting phases and bleeding phases. The method also includes the step of feeding in the pilot-control pressure via a pilot-control line for outputting a brake pressure to wheel brakes of the vehicle.

Method for controlling a pneumatic brake system and a pneumatic brake system for a vehicle

A valve device for a pneumatically-operated vehicle brake system can adjust the pneumatic brake pressure that can be fed to a brake in a controlled manner. A first variant of the valve device is configured as a modulator for use in an electronically regulated embodiment of the brake system; and a second variant is configured for use in a pneumatically controlled embodiment of the brake system. However, both variants have pneumatic interfaces and mechanical fastening points that are configured substantially identically with respect to one another to facilitate conversion of the brake system from one such embodiment to another.

Valve device for a pneumatically operated brake system

A valve device for brake control of a different pressure medium-operated vehicle brake systems comprises a housing that has pressure medium ducts. A relay valve provides a pneumatic control pressure, which is fed to the relay valve via at least one of the pressure medium ducts at a higher flow rate. At least one insert is pneumatically connected to at least two of the pressure medium ducts, which can be pneumatically connected to each other by the insert. The two pressure medium ducts define a pressure medium path, the profile of which differs based on the housing that is in each case selected and/or switched based on the selected insert. The housing is selected from a set of housings having different pressure medium ducts, in particular bores, but which are otherwise essentially similar. The insert is selected from a set of different inserts.

Valve device adaptable for brake control of a variety of pressure medium-operated vehicle brake systems

An automatic deceleration control apparatus for a vehicle operates so as to secure appropriate tire grip performance, depending on the conditions of a road surface on which the vehicle runs turning, and restrain excessive rolling of the vehicle body, there by stabilizing the turning behavior of the vehicle at all times. While the vehicle is turning on a high-friction road surface without undergoing haw moment control, a safe vehicle speed is computed within the rollover limit of the vehicle. While the vehicle is turning on a low-friction road surface under haw moment control, on the other hand, a safe vehicle speed that ensures satisfactory tire grip performance is computed in accordance with an estimated road friction coefficient. When the vehicle is about to exceed its safe speed as it turns, it is automatically decelerated to the safe speed or below. Thus, the vehicle can be prevented from spinning, drifting out, or rolling over.
