| 20090309414 | HILLHOLD BRAKING FUNCTION HAVING INTEGRATED SLIDING TEST - A method for securing a stationary vehicle against unintended rolling, in which the braking pressure occurring in a braking operation is automatically locked in at a plurality of wheel brakes in order to keep the vehicle at standstill, and in which a sliding test is implemented in addition in order to detect sliding of the vehicle. The running time of a pump for reducing the braking pressure at the wheel brake of a test wheel may be shortened considerably if the generation of braking pressure at the wheel brake of the remaining wheel is restricted or completely prevented since less or no brake fluid has to be pumped out in this case. | 12-17-2009 |
| 20100033009 | Method and Device for Tightening a Hydraulic Parking Brake - A method and a device for tightening a hydraulic parking brake are disclosed. In the method, a tightening force is generated in a first step by creating a hydraulic pressure in a parking brake circuit. To this end, a pressure generating unit driven by an electric motor is used. In a subsequent step, at least one motor-related parameter which permits a conclusion about the hydraulic pressure prevailing in the parking brake circuit is detected. Subsequently, an activation of a tightening force assistance device takes place depending on the detected motor-related parameter and without the necessity of providing a pressure sensor. | 02-11-2010 |
| 20100045101 | DEACTIVATING A SAFETY FUNCTION BY BRAKING - A method for deactivating a safety function, in which the deactivation is implemented as a function of a braking operation implemented by the driver. | 02-25-2010 |
| 20100066164 | BRAKING CONTROL DEVICE - There is provided a braking control device whereby operating noise caused by the drive frequency of the proportional electromagnetic valve can be reduced without reducing the performance of fluid pressure control. A braking control device ( | 03-18-2010 |
| 20110148186 | METHOD AND DEVICE FOR ACTIVATING A SWITHCHOVER VALVE IN THE CONTEXT OF A HILL-HOLDING FUNCTION - A method for activating the switchover valve of a brake circuit which is configured to build up brake pressure independently of the driver within the context of a vehicle standstill-holding function, is described, in which: the vehicle standstill is detected and, as long as the driver operates the brake during the standstill, the switchover valve is activated via a first current intensity other than zero (iUSV1) during a first phase; and the switchover valve is activated via a second current intensity other than zero (iUSV2) during a subsequent second phase; the first current intensity being selected in such a way that the switchover valve just closes at this current intensity; and the second current intensity being selected in such a way that the switchover valve is securely closed at this current intensity. | 06-23-2011 |
| 20110169323 | Vehicle Launch Startup Clutch Protection on a Grade - A method for controlling a vehicle powertrain includes holding the vehicle stopped on a grade by automatically producing wheel brake torque while driver demand torque is less than wheel brake torque, automatically releasing wheel brake torque when driver demand torque equals or exceeds wheel brake torque, and launching the vehicle using engine torque. | 07-14-2011 |
| 20120161508 | BRAKE CONTROL - A brake control system for a motor vehicle having wheels, service brakes for supplying a service braking effort to a plurality of the wheels, sensing means for detecting standstill of the vehicle, and a parking brake engageable to supply a park braking effort to a subset of the plurality of wheels. The system comprises brake actuation means for actuating the service brakes to supply the service braking effort; and brake control means for controlling the brake actuation means to supply an automatic component of the service braking effort. The brake control means is arranged, when standstill of the vehicle is detected and before the parking brake is engaged, to cause the brake actuation means to supply the automatic component of the service braking effort only to the subset of the plurality of wheels. | 06-28-2012 |
| 20120200148 | BRAKE CONTROL DEVICE - A brake control device for a brake system. The control device can perform both an interlocking brake control and an antilock brake control. The brake system includes a front-wheel hydraulic circuit, a front-wheel-side braking part; a rear-wheel hydraulic circuit, a rear-wheel-side braking part; and an electrically-operated pump which pressurizes the brake fluid. The brake control device includes a usual voltage mode where the interlocking brake control or the anti-lock brake control is performed when the supply voltage is a first voltage or more, and a low voltage mode where at least one of the interlocking brake control and the anti-lock brake control is performed in a limited manner when the supplied voltage is a second, lower voltage. An operation mode is changed from the usual voltage mode to the low voltage mode when it is determined that the supply voltage becomes lower than the first voltage. | 08-09-2012 |

| 20090273232 | Electronic braking system and method for drawbar trailers - A system and method for braking a drawbar trailer having a front axle and one or more further axles, each axle having at least two wheels, includes first sensors which sense the axle load of at least one axle, and second sensors which sense the rotational wheel speeds. Brakes actuatable with a pneumatic brake pressure brake the trailer. Brake signals generated in the towing vehicle are transmitted between the towing vehicle and the trailer. A control unit receives these brake signals and the sensor signals, and determines the axle load. The operating pressure is adapted to the brake pressure which is fed to the brakes. The control unit detects the brake pressure value as a function of (i) the specific axle loads of the front axle and the other axles and (ii) the received brake signals, and actuates the brakes such that the detected brake pressure is made available. | 11-05-2009 |
