A method for operating a brake system of a motor vehicle includes actuating at least one of a first actuation device and a second actuation device of the brake system, and, in the event of a fault in a hydraulic brake device of the brake system, producing an electromechanical braking force via an electromechanical brake device of the brake system for decelerating the motor vehicle, irrespective of which of the first actuation device and the second actuation device is actuated.

A driving support apparatus is provided with: a determinator configured to determine a collision probability; and a braking controller programmed to perform a braking control, and a preliminary braking control. The braking controller includes: a braking force increaser configured to increase the braking force applied in the preliminary braking control; and a braking force adjuster configured to perform adjustment, if the braking force applied at an end time point of the preliminary braking control is greater than the braking force applied at a start time point of the braking control in such a manner that a braking force applied in transferring from the preliminary braking control to the braking control has a small change amount, or in such a manner that it is greater than the braking force applied at the end time point of the preliminary braking control.

A brake assist system comprising an intermediate spring combined with a compression thrust bearing, limiting the compression to a force greater than the response of the brake pedal under normal operating conditions. The spring and its compression thrust bearing are placed between the plunger piston (2) and the helper piston so that the spring transmits the thrust from the helper piston to the plunger piston that pulls the pedal under normal braking conditions. The helper piston pushes the plunger piston by way of the compression thrust bearing when the response of the plunger piston exceeds the compression threshold. A contact detector detects the contact between the helper piston and the thrust bearing.

A method for activating a parking brake of a motor vehicle, wherein the parking brake is activated automatically if the motor vehicle is at a standstill or its ignition is switched off. The motor vehicle and/or the environment is detected subsequent to the automatic activation of the parking brake, and that said current situation is compared to stored situations of the motor vehicle and/or the environment, for which a rolling capability of the motor vehicle at a standstill and/or with its ignition switched off has been designated.

A brake system includes a piston configured to generate hydraulic pressure of brake fluid stored in a brake system, and an electronic control unit (ECU) configured to calculate hydraulic pressure to be generated in response to an amount of movement of the piston. The ECU estimates a current temperature of the brake fluid, calculates a maximum estimated hydraulic pressure of the piston based on the estimated current temperature, and determines a maximum hydraulic-pressure reference value for backward movement control of the piston based on the maximum estimated hydraulic pressure.

An electrohydraulic brake apparatus includes: a reservoir; a stroke sensor; a plurality of wheel brake assemblies; a main master cylinder; an electric booster; an electronic stability control system; and an electronic control unit configured to control the ESC system so that a fluid pressure supplied to the ESC system brakes only part of the plurality of wheel brake assemblies when the pedaling amount is less than or equal to a first reference, and to control the ESC system so that the fluid pressure supplied to the ESC system brakes all of the plurality of wheels brake assemblies when the pedaling amount is greater than the first reference.

A control device and a method for operating a hydraulic braking system of a vehicle, a volume supplementation in a motorized plunger device being effectuatable by moving a plunger of the motorized plunger device at a maximum movement speed by a maximum movement travel in a pressure reduction direction, at least one setpoint variable regarding the maximum movement speed and/or the maximum movement travel of the plunger during the subsequent volume supplementation being established, before the volume supplementation, with consideration of at least one provided variable regarding current driving situation information and/or surroundings information, and the motor of the motorized plunger device is activated during the subsequent volume supplementation with consideration of the at least one established setpoint variable.

A method for boosting a braking force in an electronically slip-controllable vehicle brake system, as well as an electronically slip-controllable vehicle brake system. Vehicle brake systems of this kind are at least equipped with a power brake unit and electronic slip-controllable vehicle brake system. In the case of a malfunction of the power brake unit, the traction-slip control device (92) takes over the boosting. A method for determining a composite signal which is adjusted by controlling a drive of a pressure generator of the slip-controllable vehicle brake system accordingly. To this end, an electronic control unit records two mutually independent input quantities, converts these input quantities into evaluation signals and sums the evaluation signals mathematically to yield a composite signal. The latter represents a setpoint brake pressure that the slip-controllable vehicle brake system supplies by controlling a pressure generator accordingly.

A driving support apparatus (10) executes collision prevention control for avoiding collision with the object when a possibility of a vehicle (VA) colliding with an object based on object information (e.g., distance, direction, and relative speed) acquired by a millimeter wave radar device (21) and a camera device (22) is high. Further, the driving support apparatus does not execute the collision prevention control when an accelerator pedal operation amount is equal to or larger than a stop threshold value. However, the driving support apparatus executes the collision prevention control even when the accelerator pedal operation amount is equal to or larger than the stop threshold value within a specific period of from a start point at which a predetermined erroneous operation condition is satisfied, to an end point, which is a time point after a predetermined consideration period has elapsed since the erroneous operation condition has no longer been satisfied.

A method for operating a braking system of a motor vehicle equipped with a wheel-slip control device, wherein the braking system includes an electrohydraulic service brake, set to generate braking forces independently of an actuation by an operator. The system having a mechanical or electromechanical parking brake actuated by an actuating element, and acting, in particular, on the rear wheels of the motor vehicle. An operator-side intent to actuate the parking brake is recognized and subsequently during the actuation of the parking brake a hydraulic pressure of the service brake is generated that acts on at least one rear wheel, of the motor vehicle capable of being braked by the parking brake. The hydraulic pressure sufficient to assist the parking brake and correspondingly lock the rear wheel of the motor vehicle braked by the parking brake during travel of the motor vehicle.
