  • Patent number: 7431132
    Abstract: A disc brake comprises a brake carrier, which is fastenable to the vehicle and is provided with bolts at the leading side and at the trailing side of the brake, which during braking take up the forces acting upon the brake linings. The relative dimensions and arrangements of the bolts and of the brake lining are such that, upon introduction of a brake force that is capable of decelerating the vehicle up to a maximum value in the region of 0.1 g, only tensile forces act upon the brake lining.

  • Patent number: 7407463
    Abstract: In a method and system for controlling a braking system, equipped with an electric parking brake, for a motor vehicle, the electric parking brake is released in response to an identification of a moving-off operation. A release instant of the electric parking brake is defined in dependence on at least one measured parameter of a clutch engagement operation. In comparison with a method and system in which, for example, the electric parking brake is released in dependence on the actuation of the accelerator by a driver, the method and system permit a more precise coordination of the deactivation of the electric parking brake with the clutch engagement operation, and thus with the moving-off operation of the vehicle, particularly in the case of a vehicle equipped with a manual transmission.

  • Patent number: 7401872
    Abstract: The present invention provides a method and a system for controlling a braking equipment of a motor vehicle in order to activate the braking equipment at a standstill of the motor vehicle such that braking forces are built up which are necessary to keep the motor vehicle in a state of standstill. To this end it is established on the basis of vehicle movements whether the vehicle is at a standstill. If vehicle movements are detected that cannot occur during driving modes of the motor vehicle, the motor vehicle is in a state of standstill. Subsequently, the braking equipment, and in particular a holding brake mechanism included in the braking equipment, are activated. In order to provide braking forces keeping the motor vehicle at a standstill also when it is on a slope, the braking equipment, and in particular the holding brake mechanism, are controlled in response of the vehicle inclination present in the state of standstill.

  • Patent number: 7338137
    Abstract: The present invention provides driveaway assistance for a motor vehicle having braking equipment which, in the standstill condition of the motor vehicle, automatically or under the control of a vehicle driver summons up braking forces needed for the standstill condition. To assist start-up (driveaway) of the motor vehicle through a reduction of the braking forces generated in the standstill condition, a driveaway request or a vehicle driver is determined when defined conditions, which are to be met for driveaway of the motor vehicle, exist in the standstill condition. Once a driveaway request has been recognized, the operating state of the motor vehicle is checked until an operating condition required for driveaway exists. Once such an operating condition is reached, the braking equipment of the motor vehicle is controlled in such a way that its braking forces generated in the standstill condition are reduced to allow driveaway of the vehicle.
