A method for maintaining a brake system in a vehicle with a hydraulic vehicle brake and an electromechanical brake device with an electric brake motor includes preparing the brake system for maintenance operations by actuating the electric brake motor to displace a transmission member into a retracted position that is remote from a brake starting position in which a brake lining is located adjacent to a brake disk of the wheel brake device. The method further includes actuating the electric brake motor to displace the transmission member in the direction of the brake starting position after completion of the maintenance operations.

The present disclosure relates to a brake system which controls a piston through force control and position control of an electronic actuator to press a disk and provide braking force and is installed in a vehicle to determine whether a failure has occurred and output a safety mode through an indicator when a failure occurs. The brake system comprises a control unit that controls a position of the electronic actuator to provide braking force and compensates the braking force based on a deceleration of the vehicle when the safety mode is output through the indicator.

The braking system including a brake input device located in the operator cabin for providing an input from an operator, at least one braking sub-system associated with the drivetrain, and a controller having at least one advanced braking feature, the braking system applying an automatic braking force in response to the at least one advance braking feature, and applying an additional progressive braking force in response to the input from the operator.

A method for operating a braking system for a motor vehicle, which has a service brake device with at least one wheel brake and a brake pressure applied to the wheel brake for generating a braking force acting on a brake disc of the wheel brake is adjusted at least temporarily depending on a setting of an operating element. A condition of a coating of a brake disc of the wheel brake is determined based on the brake pressure applied to the wheel brake and a deceleration of the motor vehicle resulting therefrom.

Provided are a brake hydraulic pressure control device and a brake system capable of generating a desired brake pressure even in a state in which a brake fluid does not easily return from a stroke simulator device to a master cylinder.

In a brake system (1) including a reservoir (31), a master cylinder (10), a stroke simulator device (40), a fluid pressure control unit (60), and a brake hydraulic pressure control device (100), the brake hydraulic pressure control device (100) acquires an imaginary stroke amount (St_est) of an input rod (5) on the basis of a pressure value (P_MC) detected by a pressure sensor (41) and controls a brake pressure (P_WC) on the basis of the imaginary stroke amount (St_est).

The disclosure relates to an electro-mechanical brake system including: an electro-mechanical brake configured to generate a braking force in each wheel according to a pedal effect applied to a brake pedal; a brake control unit configured to determine whether a wheel slip has occurred based on a wheel speed sensor values received from wheel speed sensors installed in wheels of a vehicle to set activation or deactivation of Anti-lock Braking System (ABS) control, and activate the ABS control on the electro-mechanical brake according to occurrence of a wheel slip, wherein the brake control unit is configured to obtain a first target wheel torque based on a wheel slip value and a road surface condition upon activation of the ABS control, and obtain a second target wheel torque by recalculating the first target wheel torque based on a communication delay and a mechanical response of the electro-mechanical brake.

The main innovation in the braking system presented for patent protection is that it avoids the use of a main brake valve, as well as the other cocks and valves used presently in the air brakes. The pressure in the brake chambers is regulated hydraulically or electrically at the input of each brake chamber individually. This minimizes, to the extent possible, the delay in the execution of the brake commands given by the driver. ABS control will also be individual for each wheel and will work several times faster and more accurately. Overall, the system will use much fewer air ducts, will be simpler and more secure. The diagnostics will be much faster and easier. For reequipping the vehicles with the presented braking system, no changes in their design are required.

A method for operating an electromechanical vehicle brake system is provided. The method includes determining that an activation condition has been met, selecting a pre-charge pressure based at least in part on the activation condition, building up at least an initial portion of the pre-charge pressure in the brake system, and applying at least the initial portion of the pre-charge pressure to at least one wheel brake.

A braking system for a vehicle, having a brake pedal, a position sensor unit for determining position data regarding an actuation distance and/or a pivot angle of the brake pedal of the vehicle, a force sensor unit for determining force data regarding an operating force with which the brake pedal is operated, a control unit, and an additional control unit. The position sensor unit has a signal connection to the control unit and to the additional control unit for transmitting the position data to the control unit as well as to the additional control unit. The force sensor unit has a signal connection to the control unit and to the additional control unit for transmitting the force data to the control unit as well as to the additional control unit.

Provided is a braking control device configured to apply auxiliary braking force only as needed, for example, when a travel path of a vehicle includes a curve such as a blind corner, and configured to apply the auxiliary braking force without causing a driver of the vehicle to feel uneasy about operation. The braking control device calculates target braking force based on reference braking force and input braking force information (a driver-input braking force converted value), calculates, based on the target braking force, the auxiliary braking force for reducing uneasiness (performing a process to reduce uneasiness) felt by the driver about the braking operation, and then calculates final target braking force by using the auxiliary braking force (by adding the auxiliary braking force to the driver-input braking force converted value).
