Abstract: A vehicle braking system includes a first wheel cylinder, a second wheel cylinder, a master cylinder including a first master cylinder chamber in fluid communication with the first wheel cylinder via a first circuit and a second master cylinder chamber in fluid communication with the second wheel cylinder via a second circuit, and an electronically controlled pressure generating unit separate from the master cylinder. The vehicle braking system is operable to provide braking in a first configuration in which the electronically controlled pressure generating unit pressurizes fluid, through the master cylinder, in the first circuit, to the first wheel cylinder. In the first configuration, the electronically controlled pressure generating unit pressurizes fluid in the second circuit to the second wheel cylinder, bypassing the master cylinder.

Abstract: A vehicle pedal stroke detection apparatus acquires a first value based on a physical amount regarding a magnetic flux of a magnet that is output from a stroke sensor. The first value is a physical amount regarding a magnitude of a magnetic flux density of the magnet with respect to a displacement of a push rod. Then, the vehicle pedal stroke detection apparatus compares the first value and a second value. The second value is a preset physical amount regarding the magnitude of the magnetic flux density of the magnet with respect to the displacement of the push rod.

Abstract: A method for optimizing the meterability of brake force in an ABS braking with a brake-by-wire brake system. The method includes various steps. First, a driver brake request is sensed by a pedal force simulator. In addition, a trigger point (A) of an ABS braking is recognized. In the case of a recognized ABS braking, there is a correction of the sensed driver brake request such that, upon recognizing the trigger point (A) during a reduction of the sensed driver brake request, the corrected driver brake request is reduced to the extent that ABS braking is no longer present. The corrected driver brake request is subsequently implemented by building up a corresponding brake pressure in a brake device of the brake system.

Abstract: A brake system (1) for braking a vehicle is disclosed. The brake system comprises a brake pedal control unit (4a1) configured to receive a brake pedal signal from a brake pedal sensor (21) and to respond with a primary deceleration intent signal onto a network, a brake actuator control unit (4b1) configured to activate a brake actuator (31) in response to a deceleration intent signal received from the network. The brake system (1) further comprises a central vehicle control unit (VCU) (6) that is configured to generate a secondary deceleration intent signal in response to the primary deceleration intent signal based on an overall state of the vehicle and a mode control unit (MCU) (8) to configure the brake system in an operational mode selected from at least a normal operational mode (N) and a degraded operational mode (D). The brake actuator control unit (4b1) is configured to activate the brake actuator (31) in response to a secondary deceleration intent signal in the normal operational mode and to activate the brake actuator (31) in response to the primary deceleration intent signal in the degraded operational mode (D) for applying degraded (emergency) braking to the vehicle.
