摘要： A brake system includes a reservoir and a master cylinder operable to provide a brake signal responsive to actuation of a brake pedal connected thereto. A power transmission unit is configured for selectively providing pressurized hydraulic fluid for actuating at least one of the pair of front wheel brakes and the pair of rear wheel brakes in a normal non-failure braking mode. A plurality of iso/dump valve arrangements are each hydraulically interposed between the power transmission unit and a corresponding one of the wheel brakes. A plurality of two-position three-way valves are each hydraulically connected with the master cylinder, the power transmission unit, and at least a selected wheel brake of the pair of front wheel brakes. The three-way valves selectively control hydraulic fluid flow from a chosen one of the master cylinder and the power transmission unit to the corresponding one of the front wheel brakes.

摘要： A vehicle includes a brake pedal, a master cylinder, a braking circuit with a wheel cylinder, and a brake pressure generator with strokable piston. A pedal feel simulator is coupled to the master cylinder through a switchable valve, the simulator providing a reaction force. An isolation valve closes to isolate the braking circuit from the master cylinder and the simulator circuit. A controller is programmed to place the simulator in fluid communication with an output of the brake pressure generator, and to stroke the piston at a designated diagnostic time. The resulting pressure increase is observed, and the controller checks whether the pressure-increase to piston-stroke relationship is within a predetermined acceptable range for continued operation of a brake-by-wire mode in which the master cylinder is coupled to the simulator circuit and decoupled from the braking circuit.

摘要： A method of performing a pump check for a brake system comprises determining a first position of a pump with a pump position sensor upon ignition of a vehicle. A pump motor is powered based upon a preselected operating condition. A second position of the pump is determined with the pump position sensor. The first position of the pump and the second position of the pump are compared. The pump motor is confirmed as operational when the second position of the pump is different from the first position of the pump.

摘要： An operation quantity detector detects an operation quantity. Hydraulic passage systems provide connection between hydraulic chambers of a tandem type master cylinder and wheel cylinders. A hydraulic pressure source in the hydraulic passages can pressurize the hydraulic passages based on the operation quantity. Cutoff valves each is installed in each of the hydraulic passages, between the master cylinder and the hydraulic pressure source. The hydraulic pressure detectors detect hydraulic pressures of the hydraulic passages. In the opening command state, a first mutual diagnosis based on the hydraulic pressures and the operation quantity and a second mutual diagnosis based on the hydraulic pressures are performed. In the closing command state, the first and second mutual diagnoses are performed. A failure is detected in the cutoff valves and the hydraulic pressure detecting units based on results of the first and second mutual diagnoses in the opening closing command states.

摘要： A method is described in which the wheel pressure in an electronically controlled motor vehicle brake system is determined. The brake system includes inlet valves and outlet valves in the wheel circuits. At least one of the valves allows adjusting the valve current. The basis for this are previously determined calibration values which describe the opening current behavior of the outlet valve. A verification of the wheel pressure is performed during a wheel pressure control operation by briefly opening the outlet valve of one brake circuit. The current prevailing in this case can be taken into account as an indicator for determining the wheel pressure.

摘要： A brake-by-wire system uses a time sequence type that determines road conditions before initialization, initializes EWBs (Electro Wedge Brake) at the left/right front wheels and EMBs (Electro Mechanical Brake) at the left/right rear wheels with time differences on the basis of the determined road conditions. Therefore, the clamping force in at least any one of the EWBs and the EMBs is maintained in any circumstances, thereby avoiding a situation that all the braking force of a vehicle is removed.
