| 20080196983 | Brake Actuating Unit For Actuating A Motor Vehicle Brake System - Disclosed is a brake actuating unit for actuating a motor vehicle brake system of the ‘brake-by-wire’ type. The system includes a brake booster which is operable in response to the driver's wish both by a brake pedal and by an electronic control unit. A device is provided to decouple a force-transmitting connection between the brake pedal and the brake booster in the ‘brake-by-wire’ operating mode. A master brake cylinder connected downstream of the brake booster, a device to detect a deceleration request of the driver, and a pedal travel simulator which interacts with the brake pedal and due to which a resetting force acting on the brake pedal can be simulated in the ‘brake-by-wire’ operating mode independently of an actuation of the brake booster, and which can be enabled in the ‘brake-by-wire’ operating mode when the force-transmitting connection between the brake pedal and the brake booster is decoupled and can be disabled outside the ‘brake-by-wire’ operating mode. The pedal travel simulator ( | 08-21-2008 |

| 20080224805 | PROPORTIONAL MAGNET - The invention relates to a proportional magnet, including a winding carried by a coil body, two pole shoes which project into the coil body from opposite sides and which are spaced apart axially from one another, and a gap provided between the pole shoes. The invention further includes a magnet armature, which is arranged within the winding in an axially displaceable manner substantially parallel to the longitudinal axis thereof. The axial movement of the magnet armature can be transmitted to a valve member. The invention still further includes an electrically conductive element, wherein the magnet armature can be moved through the element, wherein the element is formed from a basic body having an electrically conductive layer, and wherein the electrically conductive layer is applied separately to the basic body. | 09-18-2008 |
| 20090210124 | Method and device for controlling a motor vehicle comprising an electronically controlled brake system with driving dynamics control - A motor vehicle includes an electrohydraulic brake system with driving dynamics control, a master brake cylinder ( | 08-20-2009 |
| 20100005796 | Method for Creating Low Pressure In A Brake Activation Device of a Motor Vehicle Brake System - A method for creating low pressure in a brake activation device of a motor vehicle brake system, comprising a pneumatic brake force booster the interior of which is divided into at least one low-pressure chamber and one working chamber, a brake master cylinder and a pneumatic motor pump unit for creating the low pressure in the low-pressure chamber, which motor pump unit comprises a low-pressure pump and a motor driving the low-pressure pump, a low-pressure level in the low-pressure chamber or a pressure difference between the low-pressure chamber and the working chamber being detected by a sensor and the motor pump unit being activated by an electronic control unit if the pressure falls below a first predefined, lower low-pressure level Pe in the low-pressure chamber and being deactivated if a second predetermined, upper low-pressure level Pa is reached. | 01-14-2010 |
| 20100045096 | Motor/Pump Assembly - A motor and pump assembly for providing pressure to a brake actuating device of a motor vehicle brake system is described herein. The assembly comprises an electric motor and a double diaphragm pump. The pump includes a pump housing, two opposed working diaphragms, and crank drives each being coupled between the electric motor and a respective diaphragm for moving the diaphragm. A working chamber is defined between the pump housing and a working chamber cover. Each working chamber including an inlet channel, an inlet valve associated with the inlet channel, an outlet channel, and an outlet valve associated with the outlet channel, wherein the outlet channels are defined in the covers of the working chamber and in the pump housing to direct air displaced from the working chambers into an inside space of the pump housing. An air outlet unit is provided for exhausting the air from the inside space. | 02-25-2010 |
| 20100133897 | Actuating Unit for a Motor Vehicle Brake System - In order to increase the operational safety of a device which is used in a brake system of the “brake-by-wire” type and has the purpose of activating and deactivating a pedal travel simulator, an articulated connection which permits an all around pivoting movement of a piston rod is provided between a piston and the piston rod which activates the latter. | 06-03-2010 |
| 20100164277 | Servo Brake - A brake booster for a motor vehicle brake system of the brake-by-wire type, which can be activated both by means of a brake pedal and as a function of a driver's request, as well as independently of the driver's wish by means of an electronic control unit, wherein the coupling of the brake pedal, or of a force transmitting part which is permanently connected to the brake pedal, to an input member of the brake booster is embodied in such a way that the brake pedal or the force transmitting part can carry out a limited relative movement with respect to the input member. In order to minimize the friction which occurs between the force transmitting part and the input member when the brake booster is activated, the force transmitting part, and/or the input member of the brake booster are/is provided in the region of the relative movement of the two parts with respect to one another with means which reduce friction which occurs during the relative movement of the parts with respect to one another. | 07-01-2010 |
