摘要： A method for operating a brake system of a motor vehicle. The brake system includes a master brake cylinder operable by a user and a pressure generator driven by an electric motor, for generating a hydraulic system pressure, and includes at least one hydraulically operable friction brake. On the inlet side, the at least one friction brake is assigned a proportioning valve acted upon by the system pressure, to adjust a hydraulic actuating pressure for the friction brake. The pressure generator is given a setpoint value for carrying out a testing operation. The setpoint value is selected so as to be smoothed by a logistical growth function.

摘要： A method for braking a vehicle. The method includes: sensing a braking request signal which represents a target deceleration of the vehicle; generating, using a first pressure generating device, a hydraulic brake pressure in a wheel-brake cylinder based on the sensed braking request signal; detecting a fault state of the first pressure generating device; ascertaining a replacement braking request signal if a fault state of the first pressure generating device is detected, the replacement braking request signal being ascertained based on a target deceleration known at a predetermined time point prior to the detection of the fault state; and generating, using a brake pressure control system, a replacement brake pressure in the wheel-brake cylinder based on the ascertained replacement braking request signal, which brake pressure control system has a second pressure generating device which is hydraulically coupled to the wheel-brake cylinder.

摘要： A vehicle braking device includes a first pressurizing unit including a cylinder, a piston slidable in the cylinder, an electric motor that drives the piston, and an output chamber partitioned by the cylinder and the piston. The first pressurizing unit is configured such that a connection state between the output chamber and a reservoir is switched between communication and cut-off states according to the piston position, and the first pressurizing unit is capable of pressurizing fluid by decreasing a volume of the output chamber by movement of the piston to one axial direction side; a pressure sensor that detects a pressure of the output chamber; and an estimation unit that executes a position estimation process of moving the piston and estimating a switching position of the piston at which the connection state of the output chamber and the reservoir is switched based on a detection value of the pressure sensor.

摘要： A brake system for actuating at least one wheel brake includes a reservoir and a master cylinder operable to provide a brake signal responsive to actuation of a brake pedal connected thereto. The master cylinder is selectively operable during a manual push-through mode to generate brake actuating pressure to at least one output for hydraulically actuating at least one wheel brake. A power transmission unit is configured for actuating at least one of the wheel brakes in a non-failure normal braking mode. A secondary braking module is configured for selectively providing hydraulic fluid to each of the wheel brakes in an enhanced braking mode. The secondary braking module includes a pump motor driving at least one pump unit. Each pump unit is operatively connected to a fluid accumulator associated with the correlated wheel brake for selectively varying an amount of hydraulic fluid provided to the wheel brake.

摘要： A brake system for actuating a pair of front wheel brakes and a pair of rear wheel brakes is selectively operable during a manual push-through mode. A primary power transmission unit actuates at least one of wheel brakes in a normal braking mode. A secondary power transmission unit actuates the front wheel brakes in a backup braking mode. A primary electronic control unit controls at least one of the primary power transmission unit and a pair of rear brake motors. A secondary electronic control unit controls at least one of the secondary power transmission unit and the rear brake motors. An ABS modulator arrangement is hydraulically interposed between at least one of first and second three-way valves and at least a selected wheel brake. A multiplex control valve arrangement is hydraulically interposed between the secondary power transmission unit and the front wheel brakes.
