Systems and methods are provided for an automation system. The systems and methods calculate a motion trajectory of a manipulator and an end-effector. The end-effector is configured to grasp a target object. The motion trajectory defines successive positions of the manipulator and the end-effector along a plurality of via-points toward the target object. The systems and methods further acquire force/torque (F/T) data from an F/T sensor associated with the end-effector, and adjusts the motion trajectory based on the F/T data.

The present disclosure relates to a method for operating a vehicle brake. The vehicle brake includes a hydraulic service brake having an actuating piston, which for generating a first braking force component is movable, under the action of a hydraulic pressure, into an actuating position in which the actuating piston presses a friction lining against a rotatingly supported brake disc, and an electric parking brake, with an actuating element, that is designed to build up a second braking force component that acts on the brake disc. The method includes ascertaining the hydraulic pressure, determining a first braking force component, establishing a second braking force component to be set by means of the parking brake, based on the first braking force component and a desired total braking force, and establishing a position of the actuating element of the parking brake to be set.

An electric-parking-brake for a utility-vehicle, including: a feed-line for brake-pressure air; a discharge-line for brake-pressure air for a pneumatic-brake-device; a first-valve and a second-valve, each being switchable between a stable-state and an activated-state in response to electrical control-signals; and a valve-device which is connected between the feed-line and the discharge-line and exhibits a control-input, the valve device being switchable between a stable-state and an activated-state in response to control signals at the control-input, the feed-line being connected to the discharge-line in the activated-state, in which the first-valve in the stable-state or in the activated-state connects the control-input of the valve-device to the discharge-line, to retain a current-state of the valve-device when the brake-pressure air is applied to the discharge-line, and in the activated or stable state connects the control-input to the second-valve. Also described are an electric parking brake system, a utility vehicle, and a related method.

The pressure sensor functions as a first detection portion for detecting hydraulic pressure set according to operation of a brake pedal. The control unit detects the hydraulic pressure acting on the second piston portion through the pipe. The control unit controls differential pressure in the detected hydraulic pressure to a target value set according to vehicle speed.

A brake system, method for controlling the brake system and a mine vehicle having the same are provided. The brake system of the mine vehicle includes spring activated and hydraulically released brake assemblies in connection with wheels of the vehicle. The brake assemblies have hydraulic release actuators, which are pressurized for releasing the brakes. During normal operation, the release actuators are pressurized by a main brake circuit and are controlled by a brake controller. A separate release circuit and pressure source may be activated for releasing the brakes when the vehicle is disabled. The system further includes an override device for selectively depressurizing the release actuators during towing.

A motor vehicle includes at least one hydraulically actuatable wheel braking device and at least one electric drive motor. A method for operating the vehicle includes monitoring a driver behavior upon an emergency braking operation, and activating the hydraulic wheel braking device for generating a hydraulic emergency braking torque when an emergency braking operation is detected. When the emergency braking torque is detected, the drive motor is also operated as a generator in order to generate an additional electrical emergency braking torque.

A vehicle spring brake having a parking brake housing that defines a parking brake chamber and a service brake housing that defines a service brake chamber. A flexible membrane separates the parking brake chamber from the service brake chamber and flexes into and out of the service brake chamber based upon a pressure differential between an air pressure in the parking brake chamber and an air pressure in the service brake chamber. A pushrod extends out of the service brake housing when the flexible membrane flexes into the service brake chamber and retracts into the service brake housing when the flexible membrane flexes back out of the service brake chamber. A control valve controls the pressure differential to thereby control movement of the flexible membrane and the pushrod.

A hydraulic brake system for a motor vehicle with redundant braking pressure regulation is presented. The brake system comprises a first functional unit having at least one first electrical braking pressure generator which is designed to generate a braking pressure at each of a plurality of wheel brakes, and further having a valve assembly per wheel brake. The valve assembly can be actuated for braking pressure regulation at the corresponding wheel brake in order to couple a first wheel brake associated with the valve assembly either to the first braking pressure generator or to an unpressurized reservoir for hydraulic fluid. The brake system also comprises a second functional unit having at least one second electrical braking pressure generator which is designed to generate a braking pressure at each of a subset of the wheel brakes. The output of the second braking pressure generator is arranged downstream, as seen from the first braking pressure generator, of the valve assembly associated with the corresponding wheel brake. The second functional unit is also designed to perform braking pressure regulation at each wheel brake of the subset redundantly in relation to the first functional unit.
