A method for operating an electromechanical braking system for a transportation vehicle having a brake pedal, a brake master cylinder, and an electromechanical brake booster. The electromechanical brake booster includes an actuator motor for increasing or decreasing the pedal force on the brake master cylinder to boost or reduce the braking power accordingly. A change in the boosting force of the electromechanical brake booster is limited to avoid uncontrolled changes of the brake boosting.

A method for operating a brake system of a vehicle. The brake system having: a first and a second actuator for generating a hydraulic pressure in the brake system; a first control device designed to control the first actuator; and a second control device designed to control the second actuator. In the method, the brake system is monitored for emergency braking, wherein the first actuator is controlled by the first control device to generate a first hydraulic pressure for achieving a pre-specified emergency deceleration of the vehicle if emergency braking is detected. The second control device is controlled by the first control device to control the second actuator to generate a second hydraulic pressure when the deceleration that can be or is achieved by means of the first actuator is less than the pre-specified emergency deceleration.

A control device is applied to a vehicle that has a braking device configured to be able to adjust the braking force applied to the vehicle. The control device has a stopping braking force imparting unit that controls the braking device in order to apply a stopping braking force to the vehicle, as a minimum value of the braking force required to keep the vehicle stopped. The control device also has a deviation quantity deriving unit that derives a deviation quantity between a state quantity of the vehicle obtained when the stopping braking force is applied to the vehicle by the stopping braking force imparting unit and an ideal value of the state quantity of the vehicle. The control device also has a stopping braking force updating unit that updates the stopping braking force on the basis of the deviation quantity derived by the deviation quantity deriving unit.

In a method for operating a brake system of a vehicle during autonomous driving of the vehicle, a presence of status information relating to a driving command unit which controls the autonomous driving is checked by a brake control unit of the brake system. If the brake control unit detects that the status information is missing or detects status information which indicates an error of the driving command unit, a control signal which controls the autonomous driving in the longitudinal and/or transverse direction is generated by the brake control unit from current environmental data and/or driving parameters.

A method for operating a vehicle brake system, including activation of a electrohydraulic brake booster device when there is an actuation of a brake actuating element, so a brake pressure increase is brought about in a wheel brake cylinder, and decoupling of the wheel brake cylinder from a master brake cylinder of the brake system by closing a separating valve, it being ascertained, before the closing of the separating valve, whether a first quantity relating to an actuation speed of the actuation of the brake actuating element and/or a second quantity relating to a master brake cylinder pressure increase is within at least one specified normal value range, and, if warranted, the separating valve being closed without a delay, whereas otherwise the closing of the separating valve is delayed taking into account the second quantity and/or a third quantity relating to the brake pressure increase.

A braking method is used for a vehicle that has at least one front wheel and at least one rear wheel. A hydraulically actuatable brake is provided at the front wheel and the rear wheel, and an automatic parking brake is provided at the rear wheel. The braking method enables an optimal brake pressure to be built up as rapidly as possible. In a first step of an initiation phase of the braking method, the front wheel is braked by the hydraulically actuatable brakes and the rear wheel is braked exclusively by the automatic parking brake.

A method for operating a brake system for motor vehicles comprises in a normal control mode of the system, a displacement of a piston for a pressure supply device is terminated, and inlet valves of the wheel brakes are closed in the event of a specified brake condition. The normal control mode is switched to a special control mode in the event of a specified condition for the pressure supply device. In the event of the specified brake condition in the special control mode, a displacement of the piston of the pressure supply device is terminated by outputting an actuation signal to the pressure supply device, and for at least one selected wheel brake, the corresponding inlet valve is kept open and the corresponding outlet valve is opened at least temporarily while the inlet valves of the remaining wheel brakes are closed.
