An antiskid controller for controlling braking operation of a wheel of a vehicle based on an output signal provided by a wheel speed sensor coupled to the wheel may comprise a delay toggle, a switch logic for switching between an initial rate and a running rate, and a linear control used for calculating an antiskid correction signal, wherein the linear control receives one of the initial rate and the running rate, depending on a state of the switch logic. The linear control receives the initial rate upon initialization of the antiskid controller. The linear control receives the running rate after a predetermined duration or after the linear control has converged on a desired solution.

A brake system for a two-axle vehicle having a master brake cylinder. The brake system includes at least one connected brake circuit, each having front and rear wheel brake cylinders, front wheel inlet and outlet valves, rear wheel inlet and outlet valves, an accumulator chamber, and a control device via which, by opening the at least one rear wheel outlet valve, a brake fluid pressed out of master brake cylinder is displaceable via the open rear wheel outlet valve into the respectively downstream disposed accumulator chamber. When the at least one front wheel outlet valve is kept closed or closed, the control device is configured to increase and limit a brake pressure prevailing in the respectively associated front wheel brake cylinder to an accumulator chamber pressure actively prevailing in the accumulator chamber of the same brake circuit by keeping open or opening the at least one front wheel inlet valve.

The invention relates to a method for carrying out a cleaning operation for at least one braking device of a braking system in a motor vehicle, said method having the following steps: setting a braking pressure by components of the braking device in accordance with a predefined braking pressure curve, wherein the braking pressure curve, during the cleaning operation, specifies braking pressures that vary over time for the braking device, correcting a setpoint motor torque that is to be provided by a drive motor of the motor vehicle and that is dependent on a braking effect brought about by the set braking pressure,
the predefined braking pressure curve being selected such that a longitudinal deceleration of the motor vehicle, which is brought about by the predefined braking pressure curve, can be compensated for by a corresponding additional motor torque.

A vehicle braking system includes a controller that receives signals from sensors associated with vehicle disc brakes, which allow detection of a parameter indicative of a degree of noise generated from each disc brake. When noise generation is detected, the controller activates a noise attenuation function of a first type if the vehicle is braking, and of a second type if the vehicle is not braking. The first type involves reducing actuating pressure of a fluid actuator associated with the disc brake for which noise generation is detected. The second type involves temporarily activating, while the vehicle is running and not braking, the fluid actuator associated with the disc brake which is generating noise. The controller also receives signals indicative of vehicle operating parameters which allow conditions to be defined in which priority is given to vehicle safety, and in which the noise attenuation function is excluded.

In a hybrid vehicle, brake force is divided between friction brakes and regenerative braking. When the friction brakes are wet, the delivered braking force may exceed the commanded braking force resulting in a poor transition from regenerative braking to friction braking. When wet friction brakes are detected, a controller allocates more of the total braking energy to friction brakes until a threshold quantity of energy has been dissipated in the friction brakes, thus drying the friction brakes over fewer braking events than otherwise.

Example methods and apparatus to perform brake sweeping procedures on vehicle brakes are described herein. An example apparatus includes a controller to determine when a vehicle has made a turn, compare an angle at which the vehicle has turned to an angle threshold, and schedule a brake sweeping procedure based on the comparison.
