Disclosed herein an electric parking brake (EPB) system includes an EPB configured to provide a clamping force to a vehicle for parking; and a controller configured to engage the EPB; wherein the controller is configured to determine whether the vehicle is in an early stage of vehicle release or an early stage of brake pad replacement based on a driving distance and brake pad replacement information of the vehicle during a parking operation, and upon determining that the vehicle is in the early stages of vehicle release or brake pad replacement, compensate for a target clamping force of the EPB and perform the parking operation based on the compensated target clamping force.

A method for determining a state of a brake lining on a wheel brake of a brake system of a motor vehicle is disclosed. The wheel brake has an electromechanical brake actuator which is designed to build up a force, such as a braking force, acting on a brake disc of the brake system by pressing the brake lining against the brake disc, and which is assigned to a first axle of the motor vehicle. The method comprises the steps of: detecting a first wheel rotation rate and/or first wheel speed of the first motor-vehicle axle assigned to the electromechanical brake actuator; detecting a second wheel rotation rate and/or first wheel speed of the second motor-vehicle axle; and determining the state of the brake lining on the basis of the first and second wheel rotation rate and/or wheel speed. A method for operating a brake system of a motor vehicle, a computer program product, a control unit and a vehicle brake system are also disclosed.

A brake system for selectively actuating at least one wheel brake includes a reservoir and a power transmission unit for selectively providing pressurized hydraulic fluid for actuating at least a selected one of the wheel brakes during a braking event. A first electronic control unit at least partially controls at least one of the power transmission unit and a selected one of the pair of rear brake motors. A second electronic control unit at least partially controls at least one of the power transmission unit and an other one of the pair of rear brake motors. The first electronic control unit controls at least one SAP valve, an isolation valve, and a dump valve for a selected two of the wheel brakes, and the second electronic control unit controls at least one SAP valve, an isolation valve, and a dump valve for an other two of the wheel brakes.

Provided is a vehicle braking control device applicable to a vehicle equipped with an electric-powered parking braking device, a hydraulic braking device and a regenerative braking device. The braking control device comprises a first braking control unit and a second braking control unit. When a parking braking operation is performed while the vehicle is travelling, the first braking control unit implements a first braking process which increases the braking force to the vehicle by operating the hydraulic braking device. When the braking force to the vehicle needs to be increased in a situation where the first braking process is being implemented, the second braking control unit implements a second braking process which increases the braking force to the vehicle by operating the regenerative braking device.

The present disclosure is, for example, a braking control device for application in a vehicle. The braking control device includes: a hydraulic brake device that presses a braking member using hydraulic pressure toward a braked member that rotates integrally with a wheel to generate hydraulic braking force; and an electric brake device that presses the braking member using driving force of a motor toward the braked member to generate electric braking force. The braking control device adjusts the hydraulic braking force so that a vehicle speed falls within a target vehicle speed range while the vehicle is traveling on a downhill road, and replaces the hydraulic braking force with the electric braking force when at least one of the vehicle speed and the hydraulic pressure is stabilized.

A brake apparatus for a vehicle may include: a torque member having a pair of brake pads installed therein and spaced apart from each other, and configured to surround a brake disk; a caliper configured to cover the torque member, and having a gravitational center adjuster configured to adjust the position of a gravitational center toward the brake disk; a pair of guide rods configured to connect the torque member and the caliper, such that the caliper is slidably coupled to the torque member; and an actuator mounted on the caliper.

In order to determine a rotation angle signal of a DC machine precisely, reliably and in a simplified manner, a method is proposed, wherein combining of a current signal of the DC machine and a voltage signal of the DC machine is used to determine a combined signal; wherein conditioning of the combined signal is used to determine a conditioned signal; and wherein a rotation angle signal is determined by analysing signal oscillations of the conditioned signal.

The invention relates to a disc brake, comprising a brake carrier, a brake caliper, brake shoes, and an actuating piston. The brake carrier has at least one mounting point for mounting on a vehicle. The actuating piston is displaceably accommodated on the brake caliper and is actuatable for carrying out a service brake function of the disc brake. At least one further actuating piston is provided, which in the direction of its longitudinal axis is displaceably accommodated on the brake caliper. For carrying out the service brake function, the at least two actuating pistons are actuatable, and for carrying out a parking brake function, one of the actuating pistons is actuatable. The invention further relates to a disc brake system and a parking brake system.

An electro-mechanical brake includes: a brake disc; a friction pad; a pressing unit configured to press the friction pad toward the brake disc; a motor supplying power to the pressing unit; a current sensor; a position sensor configured to measure a position of the pressing unit; and an initial position calculating unit calculating at least one of a home position or a contact point of the pressing unit, wherein the pressing unit is configured to pass through a first check point at which a first current is measured, and a second check point at which a second current greater than the first current is measured, and wherein the initial position calculating unit calculates at least one of the home position or the contact point based on the first current, the first check point, the second current, and the second check point.
